We're asked to multiply 65 times 1. So literally, we just need to multiply 65, and we could write it as a times sign like that or we could write it as a dot like that but this means 65 times 1. And there's two ways to interpret this.
We need to evaluate the limit, as x approaches infinity, of 4x squared minus 5x, all of that over 1 minus 3x squared. So infinity is kind of a strange number. You can't just plug in infinity and see what happens.
And you're probably saying, hey, Sal, why are we even using L'Hopital's Rule? I know how to do this without L'Hopital's Rule. And you probably do, or you should.
limit's going to be equal to the limit as x approaches infinity of-- arbitrarily switch colors-- derivative of 8x minus 5 is just 8. Derivative of negative 6x is negative 6. And this is just going to be-- this is just a constant here.
So this limit exists. This was an indeterminate form. And the limit of this function's derivative over this function's derivative exists, so this limit must also equal negative 4/3.
L'Hopital's Rule is not the only game in town. And frankly, for this type of problem, my first reaction probably wouldn't have been to use L'Hopital's Rule first. You could have said that that first limit-- so the limit as x approaches infinity of 4x squared minus 5x over 1 minus 3x squared is equal to the limit as x approaches infinity.
Right? x squared times 5 over x is going to be 5x. Divided by-- let's factor out an x out of the numerator. So x squared times 1 over x squared minus 3.
As we begin our journey into the world of economics, I thought I would begin with a quote from one of the most famous economists of all time, the Scottish philosopher Adam Smith. And he really is kind of the first real economist in the way that we view it now.
'He intends only his own gain'.
And he is in this, as in many other cases, led by an invisible hand to promote an end which was no part of his intention. And this term "the invisible hand" is famous. Led by an invisible hand to promote an end which was no part of his intention.
So, it's policy, top-down .. 'top-down' questions. And in both macro- and micro-economics, there is especially in the modern sense of it, there is an attempt to make them rigorous, to make them mathematical. So, in either case you could start with some of the ideas, some of the philosophical ideas, so of the logical ideas, to say someone like Adam Smith might have.
"all people are gonna act in their own self-interest, or all people are going to maximize their gain", which isn't true -- human beings are motivated by a whole bunch of things. We simplify things, so we can start to deal with it kind of a mathematical way. SO you simplify it, so you can start dealing with it in a mathematical sense.
"An economist is a man who states the obvious in terms of the incomprehensible." And I'm assuming what he is talking about as the incomprehensible, he is referring to some of the 'mathy' stuff that you see in economics, and hopefully we're going to make this as comprehensible as possible. You'll see there is value in this.
"An economist is an expert know will know tomorrow why the things he predicted yesterday didn't happen today." And once again -- important to keep in the back of one's mind, because especially relevant to macro-economics, because in macro-economics there is always all sorts of prediction about the state of the economy: about what need to be done, about how long the recession will last, what will be the economic growth next year, what will inflation do ... and they often prove to be wrong. In fact, few economists even tend to agree on many of these things.

Simplify the rate of cans of soda compared to people. So this ratio here says that we have 92 cans of soda for every 28 people. What we want to do is simplify this, and really just putting this ratio, or this fraction, in simplest form.
Human beings have always observed that is you have an object that is moving, so this is a moving object, traveling to the right here, that it seems to stop on it's own. That if you do nothing to this moving object, on it's own, this object is going to come to a stop. It is going to come to rest.
And this is why, for most of human history, probably pre-history, but we definitely know the ancient Greeks all the way until the early 1600s, so for at least 2000 years, the assumption was "objects have a natural tendency to stop." Objects ... have ... tendency ... to come to rest or to stop. And if you want to keep them moving,
you have to apply some type of a net force to it. And once again, this is completly consistent with everyday human experience, this is what we've all experienced our entire lives. But then these gentlemen show up in the 1600s, and you might be surprised to see three gentlemen here, because this is about Newton's first law of motion.
So the completly opposite way of thinking. For over 2000 years, objects tend to stop on their own, if you want to keep the movement, apply a force. These guys say,
I think you're going to find that multiplying and dividing negative numbers are a lot easier than it might
So the basic rules are when you multiply two negative numbers, so let's say I had negative 2 times negative 2. First you just look at each of the numbers as if there was no negative sign. Well you say well, 2 times 2 that equals 4.
So that would be either, let's say a 1 times 1 is equal to 1, or if I said negative 1 times negative 1 is equal to positive 1 as well. Or if I said 1 times negative 1 is equal to negative 1, or negative 1 times 1 is equal to negative 1. You see how on the bottom two problems I had two different signs, positive 1 and negative 1?
So if I said negative 4 times positive 3, well 4 times 3 is 12, and we have a negative and a positive. So different signs mean negative. So negative 4 times 3 is a negative 12.
Let's do one more. Obviously, 0 divided by anything is still 0. That's pretty straightforward.

So it's pretty clear that if you were raising around to capital, going to friends and family or crowdfunding like Kickstarter or angel capital or venture capital or corporate partners, all kind of make sense for financing. Also, going to the small business administration or getting SBlR grants also fit into the financing column. But for operating capital that is money you need when your company is an ongoing concern in generating revenue--well, lease lines make sense, factoring, vendor financing.

In the last video we did a couple of lattice multiplication problems and we saw it was pretty straightforward. You got to do all your multiplication first and then do all of your addition. Well, let's try to understand why exactly it worked.
Forty-eight can be rewritten as forty plus eight. This four right here actually represents a forty. So right here we're not really multiplying seven times four, we're actually multiplying seven times forty.
Seven times forty is two hundreds. We wrote a two in the hundreds diagonal. And eight tens.
Fifty-six is just five tens and one six. So it's five tens in the tens diagonal and one six. Fifty-six.
Twenty times eight is equal to one hundred sixty. Or you could say it's one hundred-- notice the one in the one hundreds diagonal-- and six tens. That's what one hundred sixty is.
Eight plus five plus six is what?
Eight plus five is thirteen. Plus six is nineteen. But notice, we're in the tens place.
One thousand two hundred. So you write two in the hundreds place.
One thousand two hundred is the same thing as two hundreds plus one thousand. And now you only have one thousand in your thousands diagonal. And so you write that one right there.
Nine times eighty is seven hundred twenty. Seven hundreds-- this is the hundreds place. Seven hundreds and twenty-- two tens just right there.
We now have the general tools to really tackle any multiplication problems. So in this video I'm just going to do a ton of examples. So let's start off with-- and I'll start in yellow.
Twenty-four plus one is twenty-five. So eight times thirty-two was two hundred fifty-six. Now we're going to have to multiply this one, which is really a ten, times thirty-two.
Four plus six is ten. It's seventeen. And then we have one plus four is five.
Which whole numbers will make this statement true? We have the statement here where we have some brackets are less than 7. So we just have to figure out which whole numbers, if we put them here, are really less than 7.
8 is greater than 7.
Add and simplify the answer and write as a mixed number. So we have two mixed numbers here. We have a whole number part and a fraction part.
A farmer grows 531 tomatoes and is able to sell 176 of them in three days.
Given that his supply of tomatoes decreases by 176, how many tomatoes does he have remaining at the end of three days? So he starts with 531 tomatoes let me give myself a little more space to work with
-- he starts with 531 tomatoes and he is able to sell 176. He is essentially going to subtract the 176 that he is selling. If we want to figure out how many he is left with, we are going to subtract 176.
-oh- you took one away from the four and you stick that one in front on the two but you're really taking a 100 from the 500, making it 400 and then adding that 100 to the 20 here and making it 120 but your writing here is a 12 because it is 12 tens you're at the tens place so let me write it down this is the ones place this is tens place and this is the hundreds place so now that our numbers on top in the tens place is bigger than the numbers on the bottom we can subtract so we get 120-70 that is 50 or 12 minus 7 is 5 5 is in the tens place so it's really representing 50 let me circle it with the same colour so you recognise that this 5 is representing 50 then finally we're in the hundreds place so 400 -100 is 300 4-1 is 3 but this 3 represents 300 this 5 represents 50 this 5 represents 5 so we're done we get 355 the farmer is left with 355 tomatoes at the end of 3 days or 300+50+5 tomatoes.
Control
Haas Control New Graphical User Interface My name is John Nelson with Haas Automation
Notice the "Tool Offset" box is white and the rest of the boxes are colored This signals that the focus is on the "Tool Offsets" box Pressing the arrow keys immediately begins moving the cursor around this box
In previous versions of the Haas control, if I wanted to go to the work zero offsets, I would press the [OFFSET] key It's the same with the new control Now when I press the [OFFSET] key
The focus changes to the "Work Zero Offset" box And I scroll around this box to set my offsets Both offset boxes look very much the same as before
The final change to the tool offset display is the addition of the "Pocket-Tool" table here in the "Tool Offset" box Before we move on to the next screen, note that I can jog the machine axis without leaving the display Well, I've got my offsets set now so I need to load my program
The "List Program" screen now has tabs to navigate the different devices connected to the machine The program I want is on my USB memory stick So I connect it to the machine
"Cycle start to simulate"
In "Edit", I can press [CYCLE START] to go directly to graphics mode and run a program And now we have the ability to speed up and slow down the graphics processing speed with the [F3] and [F4] keys I press [RESET] to go back to "Edit" mode
The third function under the "Edit" mode is MDI When I press the [MDl] key, I get the same manual data input screen as before One press of the [PRGRM CONVRS] key toggles me between this box and the Visual Quick Code Programming system and the Intuitive Programming System if they are activated on this machine
In "Operation" mode, we have all the information needed to run the machine organized and available for access Again, the upper-left corner is the "Program" display box While executing programs that run sub-programs both the main program and the sub program will be displayed in a split-screen box
The "Remaining" timer uses the information from the "Last Cycle" timer to display the time remaining in a program In a production environment, this will allow the operator to know how much time is remaining in the cycle and make better time-management decisions when leaving the machine Now, let's go back to the keypad
Every button on the left side of the keypad performs the exact same function in the exact same way with the exception of [F3] and [F4]
[F3] now slows down the speed of the graphics and [F4] speeds up the graphics Obviously, there has been no change to the function of the letter keys and the number keys as well as the cursor navigation keys So that leaves displays
More presses toggle through the four position displays just like previous versions of the Haas control Pressing the [OFFSET] key changes the focus to the "Offset" box And successive presses toggles between the "Tool Offsets" and the "Work Zero Offsets"
Pressing the [CURNT COMDS] key displays the "Macro Variables" page And pressing [PAGE UP] or [PAGE DOWN] from here toggles through the same pages as before The new user settable "Operation Timers and Set-Up" page has been added to current commands
Under "Help", we have sub-tabs for "G-Code" and "M-Code" lists "Features", which is a quick overview of the topics covered in this video and "Index"
The "Index" sub-tab is a wealth of information on the Haas control and should be read before operating the machine
Along with the "Help" tab, there is the "Drill Table" tab, which is a tap/drill chart, and the "Calculator" tab As you can see, the look of the Haas control has changed quite a bit In reality, the operation of the machine and how the user performs functions on the machine has not changed much at all
Alright, so I've redrawn the graph from the previous examples just to make a little bit more room and what we've got so far is the original graph and the - a tree version of the graph that we built by search, some kind of data depth-first, breadth-first - any kind of search actually will do, as long as we now have these green edges pointing downward and these red no-tree edges connecting nodes that need to be connected if the edge wasn't actually part of this tree. Then we post ordered the nodes and now what do we do next.We now compute the number of descendents for each node in the graph and the number of descendents is the number of nodes that are either the node or reachable from the node by following green edges only. So this is easiest to start at the bottom here, F has just the node itself and no descendants, so it's got a number of descendant of one, same thing with G.E has one descendant, one descendent plus itself for three.
F and G and itself that it can reach no other nodes by non-tree edges and the smallest of those numbers is two. D can reach all of these nodes in itself but also by a non-tree edge it can reach this node and the smallest of those numbers is one. C can reach all of these nodes and through one of those nodes one tree edge gets it to one.
L, we want to know the largest value. For G between F and G the largest value is three.
With this algorithm in hand, we can actually do some useful analysis beyond just discovering things about the size of the components. So what I'm going to ask you to do is to take the code that I wrote and see if you can call it in a way that will answer this question. We're given a graph G that includes a node v1 and a node v2.

The heavy water reactor will use about 0.7 percent of the uranium's energy value, and the light water reactor will use about half of one percent. They both do terrible. At normal pressures, water will boil at 100 degrees Celsius.
In 2007 we used 5 billion tons of coal, 31 billion barrels of oil, and 5 trillion cubic meters of natural gas, along with 65,000 tons of uranium to produce the world's energy. I have a friend who's trying to start a rare earth mine in Missouri. "Jim, how much thorium do you think you'll be pawing up a year?" And he goes, "I think about 5,000 tons." 5,000 tons of thorium would supply the planet with all of its energy for a year.
"And there's like a zillion other places on earth that are just like my mine. It's a nice mine, but it's not unique, it's not like this is the one place on earth where this is found." Every time mankind has been able to access a new source of energy, it has led to profound societal implications.
"That's OK, Chelsea, you need to have six cars." Energy is all about reliability. Can we address those concerns by using batteries which are making great advances with nothing more than a laptop? It's a very, very expensive proposition to use battery backup for the grid.
Superconducting? Intermittent power from multiple sources. If you want to make a power transmission line, you want to make the economic case pay off for you.
Go on Oprah. Oh! How could I get in her book club?
He used to work at Oak Ridge National Labs in Tennessee and he said "Yeah, way back when, they were doing some stuff on this at Oak Ridge," he goes
"I just went to the library and I got this old book." It was written in 1958 and he said
"I've been meaning to look through it. I knew a little bit about it but not very much." So I took the book home, a big old thick book, it was about 1,000 pages, struggling really hard to try to grasp the nuclear concepts in the book but it was intriguing enough to me and it seemed really different than the kind of nuclear energy that we have now.
"It's a war right now, isn't it, sir, right? I could be on the front lines."
"Yes, you could." "OK. Yes sir.
Seaborg said, "Yes, absolutely. OK! Now, let's take the next step, poor little grad student!
"OK. Yes sir." Goes off, does the experiment, comes back and says, "Yep, you were right.
Seaborg looks at his grad student. This is December 1942, and he said, "You've just made a $50 quadrillion discovery." Grad student was like "Uhh!"
Seaborg was absolutely right. He had figured out that thorium could serve as an essentially unlimited nuclear fuel. And he knew how abundant thorium was in the crust of the Earth.
U-238 has a 5 billion year half-life, that's pretty old, that's how old the earth is, that's how old the Universe is. Uranium-235 on the other hand has a much shorter half-life, seven hundred million years. OK.
And that's how they made the first nuclear weapon, the Trinity blast in New Mexico, and that's also how they made the Nagasaki bomb, Fat Man. Seaborg says, "OK, well, maybe we can do the same thing with Thorium. Maybe we can expose it to neutrons, and we can make it into uranium-233.
Wigner was not successful in convincing the bulk of the nuclear community to take the thorium approach. They by and large said, "We're going to go the plutonium route." One of the reasons why was they had developed a great deal of understanding about plutonium from the weapons program. They had made the stuff.
I'm just teasing.
[laughter]
It's not my mom's basement so I feel better. So he goes to Oak Ridge and Wigner said, "Alvin, you've got to go there because you've got to go see if you can make this thorium work. It's that important." Alvin got it.
[laughter]
It was just absolutely nuts.
Weinberg was a practical man and he said, "Hah, nuclear powered bomber? That is probably a really dumb idea." It was rather this was the only avenue open for ORNL for continuing in reactor development.
"A high temperature reactor could be useful for other purposes even if it never propelled an airplane." He knew that to make the nuclear airplane work, they couldn't use water cooled reactors. They couldn't use high pressure reactors. They couldn't use complicated solid fuel reactors.
ICBMs were going great. The Air Force was going, "Oh, man, you know, I don't think we really need that nuclear bomber anymore."
LFTR is a molten salt reactor. All LFTRs are molten salt reactors but not all molten salt reactors are LFTRs. You've got this core fluid, a lithium beryilium salt, with uranium tetrafluoride in there.
UF6 gets stuck up at the gas station, has to give up two fluorines you know and drops from UF6 back to UF4. Whoop!
It's in solution now. So now, you've just refueled your core salt with uranium tetrafluoride. Cool trick, huh?
First into U233, and then into energy through fission. Now of course you're using up some thorium doing this. So you need to have a little feed of thorium fluoride, you need to feed some new thorium into the blanket to make up for the thorium you are consuming.
150 atmospheres, solid nuclear fuel. Fission is going on. Water is being pumped through.
Japanese representative here about TEPCO's management getting kicked out years ago for fraud and other things. They've had a history. Let me talk about today's nuclear fuel, because that is common to both boiling water reactors, pressurized water reactors and CANDUs.
Wigner didn't like solid fuel. He was a chemical engineer by training and he thought, "What kind of industrial process do we run chemically based on solids?" He goes "We don't. Everything we do, we use as liquids or gasses because we can mix them completely." You can take a liquid, you can fully mix it.
You can imagine going to your boss saying "I developed a new system", "Well how efficient is it?", "It's less than 1 percent", "Excuse me, what did you build? I think you need to go work on that again," you know. We just simply wouldn't accept this.
LFTR and make power out of it? I think that's a whole lot smarter thing to do. The other day I was debating some anti-nukes, and they were getting on LFTR because they said, "Oh, this is going to use uranium.
They want to achieve that level of prosperity and they're being supported by Peabody Coal. The National Academy of Sciences said that every freshwater fish in the United States of America now has dangerous levels of mercury in its flesh. And that mercury is coming from coal burning power plants.
Plutonium 239, for instance, has a 24,000 year half-life. That's a long time you're going to be waiting for that to decay. On the other hand, you can fission it and then those fission products will decay very rapidly and you also get an energy release and a neutron release, both of which are good.
A thousand kilograms of U-233 is roughly what we've got. Ninety percent of that'll fission. We can make about 500 to $600 million in electricity and another 50 or $60 million on the fission of the uranium-235.
Almost all of it will ultimately end up fissioning. Out of about a thousand kilograms, about 15 kilograms of plutonium-238 will be left over. This is good stuff.
's gone. We've used it all up. The Russians used to sell us some.
If you've heard sometimes about us saying "We burn up 99 percent of the fuel and there's one percent left", the one percent left is that stuff and it's worth almost as much as the stuff we burn up.
"Well, there's a possibility several things could happen. A very low probability event is that this might happen, but it's much more likely that --" "Oh, wait. Let's get back to that low probability event.
"You know, I guess it's possible that - but this is really unlikely, and the wind would have to blow this way and --" "Well, let's go that way." The poor engineer, he's thinking we're up 10^-12 now, or something like that.
And they're going, "Does Godzilla form?" "Well, you know, a double ended DNA break, I suppose in the right gene, could actually trigger an increased growth rate of hormone, which could actually lead to mild gigantism." They only wanted to know about the risks from the nuclear incident. And what they particularly wanted to know, and asked many times was what is the worst case scenario.
Godzilla is coming tomorrow. It's like "Oh man, we're like 10^-32 at this point. The proton is going to decay before this happens."
Which leads to a theory that does have substantiation in the data and that's called hormesis. Hormesis is simply a little bit is good for you and radiation appears to be one of these things where a little bit more is actually good for you and suppresses your development of cancer. And I say, well why would a little bit of radiation be good for me?
So maybe we'll look back in the future and it's meetings and gatherings like this we'll go "Man, that was where it got started. It didn't get started at Westinghouse or Atomic Energy of Canada, or GE," there's a ton we could do in this reactor that would even involve the radioactive materials.
like "Yeah, long time ago we did a really, really cool thing and everybody that did it is either retired or dead now." I'm like "Oh, well, that's not good. What can we do?" and they said "Well, they wrote a lot of papers and they wrote a lot of reports." I said "Oh, OK.
PhD in Electrical Engineer from Drexel University; very, very bright guy. They were under a non-disclosure agreement between RGOE and the Chinese government. So they get to the end of the meeting and I'm told by Oak Ridge people "You know we had this great trip.
So consequently the only operating rare earth mine that just opened up this year, according to their own filings in the USGS, produces essentially the lighter half of the lanthanide scale and in fact does have some monazites, which are a thorium rare earth enriched mineralization, which they dispose of. So what happens all across America, Canada, and South America, there are beautiful monazite deposits that have heavy rare earths which could be very commercial except for the thorium content. Mountain Pass was originally closed, according to CEO Mark Smith, because of the EPA and the state of California and some thorium that came out of a ruptured tailing site.
Well, when those got mined, there was probably some thorium that came up with it that's probably sitting in some barrels over in China right now, waiting for Dr. Jhang to finish his experiments with thorium molten salt reactors and to start putting them to use. This is the most important thing that's going to happen in the next 24 months, and whoever gets that is essentially going to control the destiny and the roll out of energy for the foreseeable future. They need to be able to realize the promise of thorium.
lot of folks' wealth and power rides on the business of moving large amounts of hydro-carbon from one place to another. You're on a billion, million dollar idea here. And to switch over from fuels like oil, gas, uranium, do you worry that might be a possible problem?
May of 1961, Congress funded Camp Century in Greenland. The assembly is still subcritical.
"Star Trek". You don't see any coal mines. We live much better lives today because we have learned how to use carbon.
We're asked to compute 3,060 divided by 36. We want to figure out how many times does 36-- I don't need to write it that big. We need to figure out how many times does 36 go into 3,060.
3 is smaller than 36, so it won't go into 3. Does 36 go into 30? No, 30 is still smaller than 36, so it won't go into that.
306 is larger than 36, and if we were to estimate it, 30 would go into 300 ten times, but this is larger than 30, so it's going to go fewer times. Maybe it's 9. I'm not sure.
What is 36 times 9? And this is kind of the art of doing these problems when you're dividing a two-digit number into something. So 6 times 9 is 54.
3 times 9 is 27, plus 5.
27 plus 5 is 32. So 36 times 9 is 324. That's still larger than 306, so we're going to have to go 36 less than that, so we're going to have to do eight times.
Eight times should work, because if you take 36 away, if you only do 8 times 36, that's going to take us below 300.
342, 136 away from that, or another way, 324 minus 36 is going to get us below 300. So let's try this out and just make sure.
8 times 6 is 48.
Put the 8 there; carry the 4. 8 times 3 is 24 plus 4 is 28. So 8 times 36 is 288 and it fits.
9 would've been too much. It would've been greater than 306, so now we can just subtract. So we have 6 minus 8.
1 is really taken from it, and then this 6 becomes a 16. Because if you think about it, this 10 was really 10 tens. It's in the tens place, so when you put a 10 there, it really means 10 tens.
So how many times does 36 go into 180? And once again, this is going to be estimation. It's not going to be six times.
6 times 30 would be 180.
6 times 36 would be too big, because 36 is bigger than 30, so let's try 5. Let's see if 5 works. So let's see.
5 times 6-- and there's a little trial and error here sometimes. 5 times 6 is 30.
Put the 0; carry the 3. We don't need that. That's from last time.
5 times 3 is 15 plus 3 is 18. It looks like it works out.
You subtract 180 from 180, your get zero, so we have no remainder. So we're left with 36 goes in 3,060 eighty-five times.
Ten of us have been abducted by aliens because they view us as being representative of the human race. And what they're going to do is they're going to test us to see if the human race is worthy of joining the intergalactic council of planets. And if we're not, they're going to kill us all and and turn Earth into a mushroom farm, because that's their oil.
Oh that's good enough. There's ten of us, and we're essentially lined up front to back, so that this guy, all he sees is the back of this guy's head. And he can also see the back of this guy's head.
There's a new reality television program, and it's called the Blue-- I should probably write it in blue-- but it's called the Blue Forehead Room.
And what they do in this reality television program-- and you'll have to bear with me, because the show probably wouldn't be that interesting to watch-- but it's interesting to predict what happens.
Today's lecture is what have we learned in entrepreneurship for the last 40 years. One of the interesting questions is why are you here? I hope you're here to find out what does it take to go from an idea to a business.
Welcome back.
Now that we hopefully have a little bit of an intuition of what a limit is, or finding the limit of a function is, let's do some problems. Some of these you might actually see on your exams or when you're actually trying to solve a general limit problem.
What is the limit as x approaches-- let's say negative 1. And let me see, what's a good-- let's say my expression is-- I'll put it in parentheses so it's cleaner.
Well, what's 2x plus 2 when x is equal to negative 1?
2 times negative 1. 2 times negative 1 plus 2 over negative 1 plus 1. Well, the numerator is negative 2 plus 2-- that equals 0-- over-- what's the denominator?
Negative 1 plus 1. Over 0. And do we know what 0 over 0 is?
Let's get started with some problems. Let's see. First problem: what is fifteen percent of forty?
So a lot of people's reflex might just be, oh, let me take twenty percent. It becomes 0.20. And multiply it times four.
And this problem says that twenty percent of x is equal to four. I think now it's in a form that you might recognize. So how do we write twenty percent as a decimal?
I'm picking numbers randomly. Let's say three is nine percent of what?
Once again, let's let x equal the number that three is nine percent of. You didn't have to write all that. Well, in that case we know that 0.09x-- 0.09, that's the same thing as nine percent of x-- is equal to three.
I'll now show you how to convert a fraction into a decimal. And if we have time, maybe we'll learn how to do a decimal into a fraction. So let's start with, what I would say, is a fairly straightforward example.
2 goes into 10, so we go 2 goes into 10 five times.
5 times 2 is 10. Remainder of 0. We're done.
So 1/2 is equal to 0.5. Let's do a slightly harder one. Let's figure out 1/3.
3 goes into-- well, 3 doesn't go into 1.
3 goes into 10 three times.
3 times 3 is 9. Let's subtract, get a 1, bring down the 0.
3 goes into 10 three times. Actually, this decimal point is right here.
3 times 3 is 9. Do you see a pattern here? We keep getting the same thing.
So 1/3 is equal to 0.33333 and it goes on forever. Another way of writing that is 0.33 repeating. Let's do a couple of, maybe a little bit harder, but they all follow the same pattern.
1 times 9 is 9.
17 minus 9 is 8. Bring down a 0.
9 goes into 80-- well, we know that 9 times 9 is 81, so it has to go into it only eight times because it can't go into it nine times.
8 times 9 is 72. 80 minus 72 is 8. Bring down another 0.
9 goes into 80 eight times.
8 times 9 is 72. And clearly, I could keep doing this forever and we'd keep getting 8's. So we see 17 divided by 9 is equal to 1.88 where the 0.88 actually repeats forever.
17/9 is equal to 1.88. I actually might do a separate module, but how would we write this as a mixed number? Well actually, I'm going to do that in a separate.
93 goes into-- I make a really long line up here because I don't know how many decimal places we'll do. And remember, it's always the denominator being divided into the numerator.
So 93 goes into 17 zero times. There's a decimal.
93 goes into 170? Goes into it one time.
1 times 93 is 93.
170 minus 93 is 77. Bring down the 0.
93 goes into 770? Let's see. It will go into it, I think, roughly eight times.
8 times 9 is 72. Plus 2 is 74. And then we subtract.
10 and 6. It's equal to 26. Then we bring down another 0.
93 goes into 26-- about two times.
2 times 3 is 6.
18. This is 74. 0.
35/1,000. But if we wanted to simplify it even more looks like we could divide both the numerator and the denominator by 5. And then, just to get it into simplest form, that equals 7/200.
(Applause) Yes, that's me on the day of my marriage. I got married when I was 24 years old.
And it's not less than a miracle that I have both my eyes and I think that is fantastic. It is. I mean when I saw those flowery Gulmohar [Flamboyant] outside my hospital window,
"Oh poor thing." There's always awkwardness. People don't know how to come and approach me.
"Hmm, what must be her story really?" "Look away!" Awkwardness, staring, and the staring is so intense sometimes that people stare and stare and stare.
"Oh god, what if it has impact on the baby?" Because I have heard that pregnant women are not supposed be seeing ugly things, things that disturb them. I myself, conform to the idea that
"Oh what a cute cuddly baby!" and maybe the dark child would be just wondering, "Ah, okay, I don't fit in."
Portrayals of media, portrayals of our own perceptions of beauty. Somebody, somewhere, said that a symmetrical face is beautiful. So, what happens to people like us then?
'So do you take your son out, and do you go out to play or do you fetch water?' She said
'I did try that, but as soon as I step out of the house, my neighbors shut the doors and go inside.' And she said
'I don't want to go out, because I don't want to scare them.' And she prefers to stay isolated in her home because that becomes a comfort, her safety. What Palash does is educate people like her.
"Is this the way one should behave?" "Is this how you want to kind of" -- because this is an accident! Accidents can happen to anyone at any given point of time!
(Applause)

We're told that Jared is twice the age of his brother, Peter. So, Jared is twice the age of his brother, Peter.
Peter is four years old.
Peter is four years old, and Jared is twice the age of his brother, Peter. So, Jared is twice Peter's age of four. And then they tell us Talia's age is 3 times Jared's age.
How old are Talia and Jared? So Talia's age is 3 times Jared's age. So let's write this down.
We have Peter is four years old.
So Peter- Peter's age- Peter's age,he's four years old.
Jared is twice the age of his brother, Peter. So Jared-Let me do that in yellow-So Jared- That's not yellow.
Jared- Jared is twice the age of his brother. So twice- twice is the same thing as two times, two times the age of his brother. We could-though- You could say Jared is twice the age of his brother.
Good morning. I'm here today to talk about autonomous flying beach balls. (Laughter)
And so we retrofit these with sensors and processors, and these robots can fly indoors. Without GPS. The robot I'm holding in my hand is this one, and it's been created by two students,
This is a picture of a recent experiment we did -- actually not so recent anymore -- in Sendai, shortly after the earthquake. So robots like this could be sent into collapsed buildings, to assess the damage after natural disasters, or sent into reactor buildings, to map radiation levels. So one fundamental problem that the robots have to solve if they are to be autonomous, is essentially figuring out how to get from point A to point B.
So the robot is obviously capable of executing any curve trajectory. So these are circular trajectories, where the robot pulls about two G's. Here you have overhead motion capture cameras on the top that tell the robot where it is 100 times a second.
(Music)
What I thought I would do is I would start with a simple request. I'd like all of you to pause for a moment, you wretched weaklings, and take stock of your miserable existence. (Laughter)
(Laughter) We need to be realistic. You can't do it all in one day.
We need to elongate the time frame upon which we judge the balance in our life, but we need to elongate it without falling into the trap of the "I'll have a life when I retire, when my kids have left home, when my wife has divorced me, my health is failing, I've got no mates or interests left." (Laughter)
Today, we're going to talk about resources, activities, and costs, and congratulations, this is your last lecture. By now, you're intimately familiar with the business model canvass. We've talked about value props, customer segments, channels, customer relationships, revenue streams.
Let me talk about India through the evolution of ideas. Now I believe this is an interesting way of looking at it because in every society, especially an open democratic society, it's only when ideas take root that things change. Slowly ideas lead to ideology,
In 1930 this country went through a Great Depression, which led to all the ideas of the state and social security, and all the other things that happened in Roosevelt's time.
In the 1980s we had the Reagan revolution, which lead to deregulation. And today, after the global economic crisis, there was a whole new set of rules about how the state should intervene. So ideas change states.
In the '60s and '70s we thought of people as a burden. We thought of people as a liability. Today we talk of people as an asset.
Again, after having lived for more than 200 years under the East India Company and under imperial rule, Indians had a very natural reaction towards globalization believing it was a form of imperialism. But today, as Indian companies go abroad, as Indians come and work all over the world,
20 years back the political slogan was, "Roti, kapada, makaan," which meant, "Food, clothing and shelter." And today's political slogan is, "Bijli, sadak, pani," which means "Electricity, water and roads." And that is a change in the mindset where infrastructure is now accepted.
So we're saying: income growing at 16 times and no growth in carbon. Therefore we will fundamentally rethink the way we look at the environment, the way we look at energy, the way we create whole new paradigms of development. Now why does this matter to you?
(Applause)
So this lecture is for facilitators and coaches, sometimes called the instructors or mentors. Why you're here is I'm just going to go through a brief explanation of what it is you're doing while the students are watching the lectures and working on their presentations and getting out of the building and presenting. What do you do?
THE ADVENTURES OF SHERLOCK HOLMES by SlR ARTHUR CONAN DOYLE ADVENTURE I.
I. To Sherlock Holmes she is always THE woman. I have seldom heard him mention her under any other name.
love for Irene Adler. All emotions, and that one particularly, were abhorrent to his cold, precise but admirably balanced mind. He was, I take it, the most perfect reasoning and observing machine that the world has seen, but as a lover he would have placed himself in a false position.
And yet there was but one woman to him, and that woman was the late Irene Adler, of dubious and questionable memory. I had seen little of Holmes lately. My marriage had drifted us away from each other.
He was still, as ever, deeply attracted by the study of crime, and occupied his immense faculties and extraordinary powers of observation in following out those clues, and clearing up those mysteries which had been abandoned as hopeless by the official police.
From time to time I heard some vague account of his doings: of his summons to
Odessa in the case of the Trepoff murder, of his clearing up of the singular tragedy of the Atkinson brothers at Trincomalee, and finally of the mission which he had accomplished so delicately and successfully for the reigning family of Holland. Beyond these signs of his activity, however, which I merely shared with all the readers of the daily press, I knew little of my former friend and companion.
One night--it was on the twentieth of March, 1888--I was returning from a journey to a patient (for I had now returned to civil practice), when my way led me through Baker Street.
"Seven!" I answered. "Indeed, I should have thought a little more.
"Then, how do you know?"
"I see it, I deduce it. How do I know that you have been getting yourself very wet lately, and that you have a most clumsy and careless servant girl?"
"My dear Holmes," said I, "this is too much. You would certainly have been burned, had you lived a few centuries ago.
It is true that I had a country walk on Thursday and came home in a dreadful mess, but as I have changed my clothes I can't imagine how you deduce it. As to Mary Jane, she is incorrigible, and my wife has given her notice, but there, again, I fail to see how you work it out."
As to your practice, if a gentleman walks into my rooms smelling of iodoform, with a black mark of nitrate of silver upon his right forefinger, and a bulge on the right side of his top-hat to show where he has secreted his stethoscope, I must be dull, indeed, if I do not pronounce him to be an active member of the medical profession." I could not help laughing at the ease with which he explained his process of deduction. "When I hear you give your reasons," I remarked, "the thing always appears to me to be so ridiculously simple that I could easily do it myself, though at each successive instance of your reasoning I am baffled until you explain your process.
"Frequently." "How often?" "Well, some hundreds of times."
"Quite so! You have not observed. And yet you have seen.
By-the-way, since you are interested in these little problems, and since you are good enough to chronicle one or two of my trifling experiences, you may be interested in this." He threw over a sheet of thick, pink-tinted note-paper which had been lying open upon the table. "It came by the last post," said he.
"There will call upon you to-night, at a quarter to eight o'clock," it said, "a gentleman who desires to consult you upon a matter of the very deepest moment. Your recent services to one of the royal houses of Europe have shown that you are one who may safely be trusted with matters which are of an importance which can hardly be exaggerated. This account of you we have from all quarters received.
"This is indeed a mystery," I remarked. "What do you imagine that it means?" "I have no data yet.
"Peculiar--that is the very word," said Holmes. "It is not an English paper at all.
"g," a "P," and a large "G" with a small "t" woven into the texture of the paper. "What do you make of that?" asked Holmes.
"Not at all. The 'G' with the small 't' stands for
'Gesellschaft,' which is the German for
'Company.' It is a customary contraction like our
'Co.'
'P,' of course, stands for 'Papier.' Now for the 'Eg.' Let us glance at our Continental
"Eglow, Eglonitz--here we are, Egria. It is in a German-speaking country--in Bohemia, not far from Carlsbad.
'Remarkable as being the scene of the death of Wallenstein, and for its numerous glass- factories and paper-mills.' Ha, ha, my boy, what do you make of that?" His eyes sparkled, and he sent up a great blue triumphant cloud from his cigarette.
As he spoke there was the sharp sound of horses' hoofs and grating wheels against the curb, followed by a sharp pull at the bell. Holmes whistled. "A pair, by the sound," said he.
"I think that I had better go, Holmes." "Not a bit, Doctor. Stay where you are.
"But your client--"
"Never mind him. I may want your help, and so may he. Here he comes.
Heavy bands of astrakhan were slashed across the sleeves and fronts of his double-breasted coat, while the deep blue cloak which was thrown over his shoulders was lined with flame-coloured silk and secured at the neck with a brooch which consisted of a single flaming beryl.
Boots which extended halfway up his calves, and which were trimmed at the tops with rich brown fur, completed the impression of barbaric opulence which was suggested by his whole appearance. He carried a broad-brimmed hat in his hand, while he wore across the upper part of his face, extending down past the cheekbones, a black vizard mask, which he had apparently adjusted that very moment, for his hand was still raised to it as he entered. From the lower part of the face he appeared to be a man of strong character, with a thick, hanging lip, and a long, straight chin suggestive of resolution pushed to the
He looked from one to the other of us, as if uncertain which to address. "Pray take a seat," said Holmes. "This is my friend and colleague, Dr.
"I promise," said Holmes. "And I."
"You will excuse this mask," continued our strange visitor. "The august person who employs me wishes his agent to be unknown to you, and I may confess at once that the title by which I have just called myself is not exactly my own."
"I was aware of it," said Holmes dryly. "The circumstances are of great delicacy, and every precaution has to be taken to quench what might grow to be an immense scandal and seriously compromise one of the reigning families of Europe.
To speak plainly, the matter implicates the great House of Ormstein, hereditary kings of Bohemia." "I was also aware of that," murmured Holmes, settling himself down in his armchair and closing his eyes.
Our visitor glanced with some apparent surprise at the languid, lounging figure of the man who had been no doubt depicted to him as the most incisive reasoner and most energetic agent in Europe. Holmes slowly reopened his eyes and looked impatiently at his gigantic client. "If your Majesty would condescend to state your case," he remarked, "I should be better able to advise you."
"Why, indeed?" murmured Holmes. "Your Majesty had not spoken before I was aware that I was addressing Wilhelm
Gottsreich Sigismond von Ormstein, Grand
Duke of Cassel-Felstein, and hereditary King of Bohemia."
"But you can understand," said our strange visitor, sitting down once more and passing his hand over his high white forehead, "you can understand that I am not accustomed to doing such business in my own person. Yet the matter was so delicate that I could not confide it to an agent without putting myself in his power. I have come incognito from Prague for the purpose of consulting you."
"Then, pray consult," said Holmes, shutting his eyes once more.
"The facts are briefly these: Some five years ago, during a lengthy visit to Warsaw, I made the acquaintance of the well-known adventuress, Irene Adler.
"Kindly look her up in my index, Doctor," murmured Holmes without opening his eyes. For many years he had adopted a system of docketing all paragraphs concerning men and things, so that it was difficult to name a subject or a person on which he could not at once furnish information. In this case I found her biography sandwiched in between that of a Hebrew rabbi and that of a staff-commander who had written a monograph upon the deep-sea fishes.
"Precisely so. But how--"
"Was there a secret marriage?" "None." "No legal papers or certificates?"
"There is the writing." "Pooh, pooh! Forgery."
"My private note-paper." "Stolen." "My own seal."
"I was mad--insane."
"You have compromised yourself seriously." "I was only Crown Prince then. I was young.
"It must be recovered."
"We have tried and failed." "Your Majesty must pay. It must be bought."
"She will not sell."
"Stolen, then." "Five attempts have been made. Twice burglars in my pay ransacked her house.
"No sign of it?" "Absolutely none." Holmes laughed.
"It is quite a pretty little problem," said he. "But a very serious one to me," returned the King reproachfully. "Very, indeed.
"To ruin me." "But how?" "I am about to be married."
"To Clotilde Lothman von Saxe-Meningen, second daughter of the King of Scandinavia. You may know the strict principles of her family. She is herself the very soul of delicacy.
"And Irene Adler?" "Threatens to send them the photograph. And she will do it.
"You are sure that she has not sent it yet?"
"I am sure." "And why?" "Because she has said that she would send it on the day when the betrothal was publicly proclaimed.
"Oh, then we have three days yet," said Holmes with a yawn. "That is very fortunate, as I have one or two matters of importance to look into just at present.
"Certainly. You will find me at the Langham under the name of the Count Von Kramm."
"Then I shall drop you a line to let you know how we progress."
"Pray do so. I shall be all anxiety."
"Then, as to money?" "You have carte blanche." "Absolutely?"
"And for present expenses?"
The King took a heavy chamois leather bag from under his cloak and laid it on the table. "There are three hundred pounds in gold and seven hundred in notes," he said. Holmes scribbled a receipt upon a sheet of his note-book and handed it to him.
The landlady informed me that he had left the house shortly after eight o'clock in the morning. I sat down beside the fire, however, with the intention of awaiting him, however long he might be. I was already deeply interested in his inquiry, for, though it was surrounded by none of the grim and strange features which were associated with the two crimes which I have already recorded, still, the nature of the case and the exalted station of his client gave it a character of its own.
With a nod he vanished into the bedroom, whence he emerged in five minutes tweed- suited and respectable, as of old.
Putting his hands into his pockets, he stretched out his legs in front of the fire and laughed heartily for some minutes.
"Well, really!" he cried, and then he choked and laughed again until he was obliged to lie back, limp and helpless, in the chair. "What is it?" "It's quite too funny.
"I can't imagine. I suppose that you have been watching the habits, and perhaps the house, of Miss Irene Adler."
"Quite so; but the sequel was rather unusual. I will tell you, however. I left the house a little after eight o'clock this morning in the character of a groom out of work.
Chubb lock to the door. Large sitting-room on the right side, well furnished, with long windows almost to the floor, and those preposterous English window fasteners which a child could open. Behind there was nothing remarkable, save that the passage window could be reached from the top of the coach-house.
"And what of Irene Adler?" I asked. "Oh, she has turned all the men's heads down in that part.
Briony Lodge once more, and to think over my plan of campaign. "This Godfrey Norton was evidently an important factor in the matter. He was a lawyer.
If the former, she had probably transferred the photograph to his keeping. If the latter, it was less likely. On the issue of this question depended whether I should continue my work at Briony
"I am following you closely," I answered. "I was still balancing the matter in my mind when a hansom cab drove up to Briony Lodge, and a gentleman sprang out.
"He was in the house about half an hour, and I could catch glimpses of him in the windows of the sitting-room, pacing up and down, talking excitedly, and waving his arms. Of her I could see nothing. Presently he emerged, looking even more flurried than before.
As he stepped up to the cab, he pulled a gold watch from his pocket and looked at it earnestly, 'Drive like the devil,' he shouted, 'first to Gross & Hankey's in Regent Street, and then to the Church of
St. Monica in the Edgeware Road. Half a guinea if you do it in twenty minutes!'
"Away they went, and I was just wondering whether I should not do well to follow them when up the lane came a neat little landau, the coachman with his coat only half- buttoned, and his tie under his ear, while all the tags of his harness were sticking out of the buckles. It hadn't pulled up before she shot out of the hall door and into it. I only caught a glimpse of her at the moment, but she was a lovely woman, with a face that a man might die for. "'The Church of St. Monica, John,' she cried, 'and half a sovereign if you reach it in twenty minutes.'
"This was quite too good to lose, Watson. I was just balancing whether I should run for it, or whether I should perch behind her landau when a cab came through the street. The driver looked twice at such a shabby fare, but I jumped in before he could object.
Come!' "'What then?' I asked. "'Come, man, come, only three minutes, or it won't be legal.'
"I was half-dragged up to the altar, and before I knew where I was I found myself mumbling responses which were whispered in my ear, and vouching for things of which I knew nothing, and generally assisting in the secure tying up of Irene Adler, spinster, to Godfrey Norton, bachelor.
It was all done in an instant, and there was the gentleman thanking me on the one side and the lady on the other, while the clergyman beamed on me in front. It was the most preposterous position in which I ever found myself in my life, and it was the thought of it that started me laughing just now.
It seems that there had been some informality about their license, that the clergyman absolutely refused to marry them without a witness of some sort, and that my lucky appearance saved the bridegroom from having to sally out into the streets in search of a best man. The bride gave me a sovereign, and I mean to wear it on my watch-chain in memory of the occasion."
"This is a very unexpected turn of affairs," said I; "and what then?"
"Well, I found my plans very seriously menaced. It looked as if the pair might take an immediate departure, and so necessitate very prompt and energetic measures on my part. At the church door, however, they separated, he driving back to the Temple, and she to her own house.
"Which are?" "Some cold beef and a glass of beer," he answered, ringing the bell. "I have been too busy to think of food, and
"I shall be delighted." "You don't mind breaking the law?" "Not in the least."
"I must discuss it while I eat, for I have not much time. It is nearly five now. In two hours we must be on the scene of action.
"And what then?" "You must leave that to me. I have already arranged what is to occur.
"I am to be neutral?" "To do nothing whatever. There will probably be some small unpleasantness.
"Yes." "You are to watch me, for I will be visible to you."
"Yes."
"And when I raise my hand--so--you will throw into the room what I give you to throw, and will, at the same time, raise the cry of fire. You quite follow me?"
"Entirely." "It is nothing very formidable," he said, taking a long cigar-shaped roll from his pocket. "It is an ordinary plumber's smoke-rocket, fitted with a cap at either end to make it self-lighting.
"I am to remain neutral, to get near the window, to watch you, and at the signal to throw in this object, then to raise the cry of fire, and to wait you at the corner of the street."
"Precisely." "Then you may entirely rely on me." "That is excellent.
It was already dusk, and the lamps were just being lighted as we paced up and down in front of Briony Lodge, waiting for the coming of its occupant.
The house was just such as I had pictured it from Sherlock Holmes' succinct description, but the locality appeared to be less private than I expected. On the contrary, for a small street in a quiet neighbourhood, it was remarkably animated. There was a group of shabbily dressed men smoking and laughing in a corner, a scissors-grinder with his wheel, two guardsmen who were flirting with a nurse- girl, and several well-dressed young men who were lounging up and down with cigars in their mouths.
"Where, indeed?" "It is most unlikely that she carries it about with her. It is cabinet size.
"Where, then?" "Her banker or her lawyer. There is that double possibility.
"But it has twice been burgled."
"Pshaw! They did not know how to look."
"But how will you look?"
"I will not look."
"What then?" "I will get her to show me." "But she will refuse."
At his fall the guardsmen took to their heels in one direction and the loungers in the other, while a number of better-dressed people, who had watched the scuffle without taking part in it, crowded in to help the lady and to attend to the injured man.
Irene Adler, as I will still call her, had hurried up the steps; but she stood at the top with her superb figure outlined against the lights of the hall, looking back into the street. "Is the poor gentleman much hurt?" she asked. "He is dead," cried several voices.
"He's a brave fellow," said a woman. "They would have had the lady's purse and watch if it hadn't been for him. They were a gang, and a rough one, too.
"He can't lie in the street. May we bring him in, marm?"
"Surely. Bring him into the sitting-room. There is a comfortable sofa.
Briony Lodge and laid out in the principal room, while I still observed the proceedings from my post by the window. The lamps had been lit, but the blinds had not been drawn, so that I could see Holmes as he lay upon the couch. I do not know whether he was seized with compunction at that moment for the part he was playing, but I know that I never felt more heartily ashamed of myself in my life than when I saw the beautiful creature against whom I was conspiring, or the grace and kindliness with which she waited upon the injured man.
And yet it would be the blackest treachery to Holmes to draw back now from the part which he had intrusted to me. I hardened my heart, and took the smoke- rocket from under my ulster. After all, I thought, we are not injuring her.
Holmes had sat up upon the couch, and I saw him motion like a man who is in need of air. A maid rushed across and threw open the window. At the same instant I saw him raise his hand and at the signal I tossed my rocket into the room with a cry of "Fire!"
"Fire!" Thick clouds of smoke curled through the room and out at the open window. I caught a glimpse of rushing figures, and a moment later the voice of Holmes from within assuring them that it was a false alarm.
"You have the photograph?" "I know where it is." "And how did you find out?"
"I guessed as much." "Then, when the row broke out, I had a little moist red paint in the palm of my hand.
"That also I could fathom." "Then they carried me in. She was bound to have me in.
"How did that help you?" "It was all-important. When a woman thinks that her house is on fire, her instinct is at once to rush to the thing which she values most.
In the case of the Darlington substitution scandal it was of use to me, and also in the Arnsworth Castle business.
A married woman grabs at her baby; an unmarried one reaches for her jewel-box. Now it was clear to me that our lady of to- day had nothing in the house more precious to her than what we are in quest of. She would rush to secure it.
"And now?" I asked. "Our quest is practically finished.
"And when will you call?"
"At eight in the morning. She will not be up, so that we shall have a clear field. Besides, we must be prompt, for this marriage may mean a complete change in her
IIl. I slept at Baker Street that night, and we were engaged upon our toast and coffee in the morning when the King of Bohemia rushed into the room. "You have really got it!" he cried, grasping Sherlock Holmes by either shoulder and looking eagerly into his face.
"But you have hopes?" "I have hopes." "Then, come.
"We must have a cab." "No, my brougham is waiting." "Then that will simplify matters."
Briony Lodge. "Irene Adler is married," remarked Holmes. "Married!
"Yesterday." "But to whom?" "To an English lawyer named Norton."
"It is true. And yet--Well! I wish she had been of my own station!
The door of Briony Lodge was open, and an elderly woman stood upon the steps. She watched us with a sardonic eye as we stepped from the brougham. "Mr. Sherlock Holmes, I believe?" said she.
"What!" Sherlock Holmes staggered back, white with chagrin and surprise. "Do you mean that she has left England?"
"And the papers?" asked the King hoarsely. "All is lost." "We shall see."
The photograph was of Irene Adler herself in evening dress, the letter was superscribed to "Sherlock Holmes, Esq. To be left till called for." My friend tore it open and we all three read it together.
"MY DEAR MR. SHERLOCK HOLMES,--You really did it very well. You took me in completely. Until after the alarm of fire, I had not a suspicion.
"Well, I followed you to your door, and so made sure that I was really an object of interest to the celebrated Mr. Sherlock Holmes. Then I, rather imprudently, wished you good-night, and started for the Temple to see my husband.
"Very truly yours, "IRENE NORTON, née ADLER."
"What a woman--oh, what a woman!" cried the King of Bohemia, when we had all three read this epistle. "Did I not tell you how quick and resolute she was?
"On the contrary, my dear sir," cried the King; "nothing could be more successful. I know that her word is inviolate.
"I am glad to hear your Majesty say so." "I am immensely indebted to you. Pray tell me in what way I can reward you.
He used to make merry over the cleverness of women, but I have not heard him do it of late. And when he speaks of Irene Adler, or when he refers to her photograph, it is always under the honourable title of the woman.
Great job. Now that we've got the fundamentals down, we're going to build on that in the later units to create fun interactive games.

[Anderson Cooper] Thank you so much for being here. The legacy of your father, I mean, there are so many people in this room who have been inspired by your father.
Yes, actually, it's true that he has touched so many lives that we receive lots of messages from people who were inspired by his work.
No, I don't think so, because there is a lot of people in need around the world, and they are most of them voiceless.
Journalists get killed, but still they have to go onsite and report what's happening. [Cooper] Yeah.
[Cooper] So nice to see you.
First of all, just, World Humanitarian Day: why do you think this is so important? What do you hope to accomplish this year?
[Valerie Amos] Well, I think it's important for several reasons. One, it's about really honoring and remembering our colleagues who have given their lives.

Hello, and welcome. This will be the first in the series of lectures on physics. My goal is really to give you an intuitive feeling of what physics is all about, because especially on the mechanics side of things-- projectile motion, force, and momentum-- it's actually pretty intuitive.
Technically, there's a difference: velocity is a vector of measurement, and speed is a scalar. I probably have already confused you, but all you have to know is a vector has a magnitude and a direction. If I were to give a velocity, I really shouldn't just say five miles per hour.
You're going 30 meters per second, you're always going the 30 meters per second, and you'll stay going 30 meters per second. But we know from moving, generally, that your velocity isn't-- sometimes, you're stationary, then sometimes you're moving, and in order to start stationary, and then get moving, your velocity has to change. How could we describe a change in velocity?
Where I left off, we were just essentially chugging through this fairly hairy derivative-- this definite integral-- this antiderivative. It takes my brain a little while to come up with the next term. So we evaluated at 2 and now we have to subtract this evaluated at 1.
The 16 pi minus 8 pi, that equals 8 pi. And then that's a plus. The 32 plus 8 pi.
32 pi plus 8 pi, that equals 40 pi. So let's see, I've simplified it to 40 pi, and what's minus 8 times 4 is 32 pi over 3.
And then all of that, let's see if I can simplify this.
And then, let's see. Minus 4 pi over 3 minus pi over 2. So let's get a common denominator for this part right here.
120 minus 32, let's see, we get 90-- 88? Right. 88 pi over 3.
Everything is interconnected. As a Shinnecock Indian, I was raised to know this. We are a small fishing tribe situated on the southeastern tip of Long Island near the town of Southampton in New York.
"Look, do you see that? That's part of you up there. That's your water that helps to make the cloud that becomes the rain that feeds the plants that feeds the animals."
(Laughter) I'm just kidding. (Laughter)

The basic HTML for grabbing the canvas object is pretty straightforward. We've seen this before. The interesting thing that we haven't yet covered is grabbing the context of the canvas.
And the second question asks what is the maximum number of edges B can have?
CHAPTER 12 Brute Neighbors Sometimes I had a companion in my fishing, who came through the village to my house from the other side of the town, and the catching of the dinner was as much a social exercise as the eating of it. Hermit.
Angleworms are rarely to be met with in these parts, where the soil was never fattened with manure; the race is nearly extinct. The sport of digging the bait is nearly equal to that of catching the fish, when one's appetite is not too keen; and this you may have all to yourself today. I would advise you to set in the spade down yonder among the ground-nuts, where you see the johnswort waving.
Confut-see; they may fetch that state about again. There never is but one opportunity of a kind.
Mem. Poet. How now, Hermit, is it too soon?
lunch, and read a little by a spring which was the source of a swamp and of a brook, oozing from under Brister's Hill, half a mile from my field. The approach to this was through a succession of descending grassy hollows, full of young pitch pines, into a larger wood about the swamp. There, in a very secluded and shaded spot, under a spreading white pine, there was yet a clean, firm sward to sit on.
Concord Fight! Two killed on the patriots' side, and Luther Blanchard wounded! Why here every ant was a Buttrick--"Fire! for God's sake fire!"--and thousands shared the fate of Davis and Hosmer.
Hotel des Invalides, I do not know; but I thought that his industry would not be worth much thereafter. I never learned which party was victorious, nor the cause of the war; but I felt for the rest of that day as if I had had my feelings excited and harrowed by witnessing the struggle, the ferocity and carnage, of a human battle before my door.
Kirby and Spence tell us that the battles of ants have long been celebrated and the date of them recorded, though they say that Huber is the only modern author who appears to have witnessed them.
"Aeneas Sylvius," say they, "after giving a very circumstantial account of one contested with great obstinacy by a great and small species on the trunk of a pear tree," adds that "this action was fought in the pontificate of Eugenius the Fourth, in the presence of Nicholas Pistoriensis, an eminent lawyer, who related the whole history of the battle with the greatest fidelity." A similar engagement between great and small ants is recorded by Olaus Magnus, in which the small ones, being victorious, are said to have buried the bodies of their own soldiers, but left those of their giant enemies a prey to the birds. This event happened previous to the expulsion of the tyrant Christiern the
At length having come up fifty rods off, he uttered one of those prolonged howls, as if calling on the god of loons to aid him, and immediately there came a wind from the east and rippled the surface, and filled the whole air with misty rain, and I was impressed as if it were the prayer of the loon answered, and his god was angry with me; and so I left him disappearing far away on the tumultuous surface. For hours, in fall days, I watched the ducks cunningly tack and veer and hold the middle of the pond, far from the sportsman; tricks which they will have less need to practise in Louisiana bayous.
In these days of fatted cattle and waving grain-fields this humble root, which was once the totem of an Indian tribe, is quite forgotten, or known only by its flowering vine; but let wild Nature reign here once more, and the tender and luxurious English grains will probably disappear before a myriad of foes, and without the care of man the crow may carry back even the last seed of corn to the great cornfield of the Indian's God in the southwest, whence he is said to have brought it; but the now almost exterminated ground-nut will perhaps revive and flourish in spite of frosts and wildness, prove itself indigenous, and resume its ancient importance and dignity as the diet of the hunter tribe. Some Indian Ceres or Minerva must have been the inventor and bestower of it; and when the reign of poetry commences here, its leaves and string of nuts may be represented on our works of art.
Like the wasps, before I finally went into winter quarters in November, I used to resort to the northeast side of Walden, which the sun, reflected from the pitch pine woods and the stony shore, made the fireside of the pond; it is so much pleasanter and wholesomer to be warmed by the sun while you can be, than by an artificial fire.
I thus warmed myself by the still glowing embers which the summer, like a departed hunter, had left. When I came to build my chimney I studied masonry. My bricks, being second-hand ones, required to be cleaned with a trowel, so that I
"an oil and wine cellar, many casks, so that it may be pleasant to expect hard times; it will be for his advantage, and virtue, and glory." I had in my cellar a firkin of potatoes, about two quarts of peas with the weevil in them, and on my shelf a little rice, a jug of molasses, and of rye and Indian meal a peck each. I sometimes dream of a larger and more populous house, standing in a golden age, of enduring materials, and without gingerbread work, which shall still consist of only one room, a vast, rude, substantial, primitive hall, without ceiling or plastering, with bare rafters and purlins supporting a sort of lower heaven over one's head--useful to keep off rain and snow, where the king and queen posts stand out to receive your homage, when you have done reverence to the prostrate Saturn of an older dynasty on stepping over the sill; a cavernous house, wherein you must reach up a torch upon a pole to see the roof; where some may live in the fireplace, some in the recess of a window, and some on settles, some at one end of the hall, some at another, and some aloft on rafters with the spiders, if they choose; a house which you have got into when you have opened the outside door, and the ceremony is over; where the weary traveller may wash, and eat, and converse, and sleep, without further journey; such a shelter as you would be glad to reach in a tempestuous night, containing all the essentials of a house, and nothing for house-keeping; where you can see all the treasures of the house at one view, and everything hangs upon its peg, that a man should use; at once kitchen, pantry, parlor, chamber, storehouse, and garret; where you can see so necessary a thing, as a barrel or a ladder, so convenient a thing as a cupboard, and hear the pot boil, and pay your respects to the fire that cooks your dinner, and the oven that bakes your bread, and the necessary furniture and utensils are the chief ornaments; where the washing is not put out, nor the fire, nor the mistress, and perhaps you are sometimes requested to move from off the trap-door, when the cook would descend into the cellar, and so learn whether the ground is solid or hollow beneath you without stamping.
I had the previous winter made a small quantity of lime by burning the shells of the Unio fluviatilis, which our river affords, for the sake of the experiment; so that I knew where my materials came from. I might have got good limestone within a mile or two and burned it myself, if I had cared to do so. The pond had in the meanwhile skimmed over in the shadiest and shallowest coves, some days or even weeks before the general freezing.
Night after night the geese came lumbering in the dark with a clangor and a whistling of wings, even after the ground was covered with snow, some to alight in Walden, and some flying low over the woods toward Fair Haven, bound for Mexico. Several times, when returning from the village at ten or eleven o'clock at night, I heard the tread of a flock of geese, or else ducks, on the dry leaves in the woods by a pond-hole behind my dwelling, where they had come up to feed, and the faint honk or quack of their leader as they hurried off.
In 1845 Walden froze entirely over for the first time on the night of the 22d of December, Flint's and other shallower ponds and the river having been frozen ten days or more; in '46, the 16th; in '49, about the 31st; and in '50, about the 27th of December; in '52, the 5th of January; in
'53, the 31st of December. The snow had already covered the ground since the 25th of November, and surrounded me suddenly with the scenery of winter. I withdrew yet farther into my shell, and endeavored to keep a bright fire both within my house and within my breast.
Gilpin, in his account of the forest borderers of England, says that "the encroachments of trespassers, and the houses and fences thus raised on the borders of the forest," were "considered as great nuisances by the old forest law, and were severely punished under the name of purprestures, as tending ad terrorem ferarum--ad nocumentum forestae, etc.," to the frightening of the game and the detriment of the forest. But I was interested in the preservation of the venison and the vert more than the hunters or woodchoppers, and as much as though I had been the Lord Warden himself; and if any part was burned, though I burned it myself by accident, I grieved with a grief that lasted longer and was more inconsolable than that of the proprietors; nay, I grieved when it was cut down by the proprietors themselves. I would that our farmers when they cut down a forest felt some of that awe which the old Romans did when they came to thin, or let in the light to, a consecrated grove (lucum conlucare), that is, would believe that it is sacred to some god.
Michaux, more than thirty years ago, says that the price of wood for fuel in New York and Philadelphia "nearly equals, and sometimes exceeds, that of the best wood in Paris, though this immense capital annually requires more than three hundred thousand cords, and is surrounded to the distance of three hundred miles by cultivated plains." In this town the price of wood rises almost steadily, and the only question is, how much higher it is to be this year than it was the last.
When the villagers were lighting their fires beyond the horizon, I too gave notice to the various wild inhabitants of Walden vale, by a smoky streamer from my chimney, that I was awake.-- Light-winged Smoke, Icarian bird, Melting thy pinions in thy upward flight, Lark without song, and messenger of dawn, Circling above the hamlets as thy nest;
"Never, bright flame, may be denied to me Thy dear, life imaging, close sympathy. What but my hopes shot upward e'er so bright? What but my fortunes sunk so low in night?

Ingraham, Esquire, gentleman, of Concord village, who built his slave a house, and gave him permission to live in Walden Woods;--Cato, not Uticensis, but Concordiensis. Some say that he was a Guinea Negro.
Cato's half-obliterated cellar-hole still remains, though known to few, being concealed from the traveller by a fringe of pines. It is now filled with the smooth sumach (Rhus glabra), and one of the earliest species of goldenrod (Solidago stricta) grows there luxuriantly. Here, by the very corner of my field, still nearer to town, Zilpha, a colored woman, had her little house, where she spun linen for the townsfolk, making the Walden Woods ring with her shrill singing, for she had a loud and notable voice.
One old frequenter of these woods remembers, that as he passed her house one noon he heard her muttering to herself over her gurgling pot--"Ye are all bones, bones!" I have seen bricks amid the oak copse there. Down the road, on the right hand, on Brister's Hill, lived Brister Freeman, "a handy Negro," slave of Squire Cummings once--there where grow still the apple trees which Brister planted and tended;
Not long since I read his epitaph in the old Lincoln burying-ground, a little on one side, near the unmarked graves of some British grenadiers who fell in the retreat from Concord--where he is styled "Sippio
Brister"--Scipio Africanus he had some title to be called--"a man of color," as if he were discolored. It also told me, with staring emphasis, when he died; which was but an indirect way of informing me that he ever lived. With him dwelt Fenda, his hospitable wife, who told fortunes, yet pleasantly--large, round, and black, blacker than any of the children of night, such a dusky orb as never rose on Concord before or since.
Brister's Hill, but was long since killed out by pitch pines, excepting a few stumps, whose old roots furnish still the wild stocks of many a thrifty village tree. Nearer yet to town, you come to Breed's location, on the other side of the way, just on the edge of the wood; ground famous for the pranks of a demon not distinctly named in old mythology, who has acted a prominent and astounding part in our New England life, and deserves, as much as any mythological character, to have his biography written one day; who first comes in the guise of a friend or hired man, and then robs and murders the whole family-- New-England Rum. But history must not yet tell the tragedies enacted here; let time intervene in some measure to assuage and lend an azure tint to them.
"Gondibert," that winter that I labored with a lethargy--which, by the way, I never knew whether to regard as a family complaint, having an uncle who goes to sleep shaving himself, and is obliged to sprout potatoes in a cellar Sundays, in order to keep awake and keep the Sabbath, or as the consequence of my attempt to read Chalmers' collection of English poetry without skipping. It fairly overcame my Nervii.
"tub," and a full frog-pond by, we could turn that threatened last and universal one into another flood. We finally retreated without doing any mischief--returned to sleep and
"Gondibert." But as for "Gondibert," I would except that passage in the preface about wit being the soul's powder--"but most of mankind are strangers to wit, as Indians are to powder." It chanced that I walked that way across the fields the following night, about the same hour, and hearing a low moaning at this spot, I drew near in the dark, and discovered the only survivor of the family that I know, the heir of both its virtues and its vices, who alone was interested in this burning, lying on his stomach and looking over the cellar wall at the still smouldering cinders beneath, muttering to himself, as is his wont.
Quoil, he was called. Rumor said that he had been a soldier at Waterloo. If he had lived I should have made him fight his battles over again.
Brister pulled wool"; which is about as edifying as the history of more famous schools of philosophy. Still grows the vivacious lilac a generation after the door and lintel and the sill are gone, unfolding its sweet- scented flowers each spring, to be plucked by the musing traveller; planted and tended once by children's hands, in front-yard plots--now standing by wallsides in retired pastures, and giving place to new-rising forests;--the last of that stirp, sole survivor of that family. Little did the dusky children think that the puny slip with its two eyes only, which they stuck in the ground in the shadow of the house and daily watered, would root itself so, and outlive them, and house itself in the rear that shaded it, and grown man's garden and orchard, and tell their story faintly to the lone wanderer a half-century after they had grown up and died--blossoming as fair, and smelling as sweet, as in that first spring.
In Goose Pond, which lay in my way, a colony of muskrats dwelt, and raised their cabins high above the ice, though none could be seen abroad when I crossed it.
Walden, being like the rest usually bare of snow, or with only shallow and interrupted drifts on it, was my yard where I could walk freely when the snow was nearly two feet deep on a level elsewhere and the villagers were confined to their streets. There, far from the village street, and except at very long intervals, from the jingle of sleigh-bells, I slid and skated, as in a vast moose-yard well trodden, overhung by oak woods and solemn pines bent down with snow or bristling with icicles. For sounds in winter nights, and often in winter days, I heard the forlorn but melodious note of a hooting owl indefinitely far; such a sound as the frozen earth would yield if struck with a suitable plectrum, the very lingua vernacula of Walden Wood, and quite familiar to me at last, though I never saw the bird while it was making it.
Concord, as if it were restless in its bed and would fain turn over, were troubled with flatulency and had dreams; or I was waked by the cracking of the ground by the frost, as if some one had driven a team against my door, and in the morning would find a crack in the earth a quarter of a mile long and a third of an inch wide. Sometimes I heard the foxes as they ranged over the snow-crust, in moonlight nights, in search of a partridge or other game, barking raggedly and demoniacally like forest dogs, as if laboring with some anxiety, or seeking expression, struggling for light and to be dogs outright and run freely in the streets; for if we take the ages into our account, may there not be a civilization going on among brutes as well as men? They seemed to me to be rudimental, burrowing men, still standing on their defence, awaiting their transformation.
One would approach at first warily through the shrub oaks, running over the snow-crust by fits and starts like a leaf blown by the wind, now a few paces this way, with wonderful speed and waste of energy, making inconceivable haste with his "trotters," as if it were for a wager, and now as many paces that way, but never getting on more than half a rod at a time; and then suddenly pausing with a ludicrous expression and a gratuitous somerset, as if all the eyes in the universe were eyed on him--for all the motions of a squirrel, even in the most solitary recesses of the forest, imply spectators as much as those of a dancing girl--wasting more time in delay and circumspection than would have sufficed to walk the whole distance--I never saw one walk--and then suddenly, before you could say Jack Robinson, he would be in the top of a young pitch pine, winding up his clock and chiding all imaginary spectators, soliloquizing and talking to all the universe at the same time--for no reason that I could ever detect, or he himself was aware of, I suspect. At length he would reach the corn, and selecting a suitable ear, frisk about in the same uncertain trigonometrical way to the topmost stick of my wood-pile, before my window, where he looked me in the face, and there sit for hours, supplying himself with a new ear from time to time, nibbling at first voraciously and throwing the half- naked cobs about; till at length he grew more dainty still and played with his food, tasting only the inside of the kernel, and the ear, which was held balanced over the stick by one paw, slipped from his careless grasp and fell to the ground, when he would look over at it with a ludicrous expression of uncertainty, as if suspecting that it had life, with a mind not made up whether to get it again, or a new one, or be off; now thinking of corn, then listening to hear what was in the wind.
A little flock of these titmice came daily to pick a dinner out of my woodpile, or the crumbs at my door, with faint flitting lisping notes, like the tinkling of icicles in the grass, or else with sprightly day day day, or more rarely, in spring-like days, a wiry summery phe-be from the woodside. They were so familiar that at length one alighted on an armful of wood which I was carrying in, and pecked at the sticks without fear. I once had a sparrow alight upon my shoulder for a moment while I was hoeing in a village garden, and I felt that I was more distinguished by that circumstance than I should have been by any epaulet I could have worn.
I used to start them in the open land also, where they had come out of the woods at sunset to "bud" the wild apple trees. They will come regularly every evening to particular trees, where the cunning sportsman lies in wait for them, and the distant orchards next the woods suffer thus not a little. I am glad that the partridge gets fed, at any rate.
Late in the afternoon, as he was resting in the thick woods south of Walden, he heard the voice of the hounds far over toward Fair Haven still pursuing the fox; and on they came, their hounding cry which made all the woods ring sounding nearer and nearer, now from Well Meadow, now from the Baker Farm. For a long time he stood still and listened to their music, so sweet to a hunter's ear, when suddenly the fox appeared, threading the solemn aisles with an easy coursing pace, whose sound was concealed by a sympathetic rustle of the leaves, swift and still, keeping the round, leaving his pursuers far behind; and, leaping upon a rock amid the woods, he sat erect and
The Concord hunter told him what he knew and offered him the skin; but the other declined it and departed. He did not find his hounds that night, but the next day learned that they had crossed the river and put up at a farmhouse for the night, whence, having been well fed, they took their departure early in the morning. The hunter who told me this could remember one Sam Nutting, who used to hunt bears on
Fair Haven Ledges, and exchange their skins for rum in Concord village; who told him, even, that he had seen a moose there. Nutting had a famous foxhound named Burgoyne--he pronounced it Bugine--which my informant used to borrow. In the "Wast Book" of an old trader of this town, who was also a captain, town-clerk, and representative, I find the following entry.
18th, 1742-3, "John Melven Cr. by 1 Grey Fox 0--2--3"; they are not now found here; and in his ledger, Feb, 7th, 1743, Hezekiah Stratton has credit "by 1/2 a Catt skin 0-- 1--4-1/2"; of course, a wild-cat, for Stratton was a sergeant in the old French war, and would not have got credit for hunting less noble game. Credit is given for deerskins also, and they were daily sold.
(Lepus, levipes, light-foot, some think.) What is a country without rabbits and partridges? They are among the most simple and indigenous animal products; ancient and venerable families known to antiquity as to modern times; of the very hue and substance of Nature, nearest allied to leaves and to the ground--and to one another; it is either winged or it is legged. It is hardly as if you had seen a wild creature when a rabbit or a partridge bursts away, only a natural one, as much to be expected as rustling leaves.
Right, what I have right in front of me is the Khan Academy measuring angles, measuring angles exercise. I have a small part of it in this screen right over here. And it's a pretty cool exercise cause it has this little virtual protracter that we can use to actually measure angles.
lets rotate it that way, its keep rotating it i can keep it press thats better alright ,thats looks about right so, one side, is that zero mark and then my angle my other side are if there is a way points 2 looks like pretty cause to the 20˚ mark so i would type the range of the screen you are seeing that and that is the right answer and we can get the other angle so lets,try the measure this one right over here so,once again place the center of the protractor at the center at the vertex of an angle we can place the zero degree the base of the protractor at this side of the angle so we should rotate it a little bit we want to do one more time that , looks about right and the angle is now opening up this is the other side of point to 110 degrees is this larger than 90 degree its also an obtuse angle. the last one is an acute angle,this is obtuse angle 110 degrees more than 90 degrees,we typed in i got the right answer just do couple of more than these so,once again put the center the protractor at the vertex of an angle now i want to rotate it ,there we go, and this looks liking roughly an 80 degree angle but,if i am really precise 81 or 82 degrees and 80 is my best guess lets do one more of these. Vertex of my angle at the center of my protractor.and I want to put one side of my angle at 0 degrees. here are two ways to do this, you could do just this, this is not too helpful as the angle is outside the protractor.
The answer is when you're planning an initial product, the most important is finding sufficient features to solve the problem for a known group of customers. Matching competitive features is what we used to do and actually is a going out of business strategy. And unless you're in an existing market and you happen to know which features the customers have told you are more important.
Round 24,259 to the nearest hundred. You're going to find that doing these problems are pretty straightforward, but what I want to do is just think about what it means to round to the nearest hundred. So what I'm going to do is I'm going to draw a number line.
So maybe we have 24,100, and then we go to 24,200, then we go to 24,300, and then we go to 24,400. I think you see what I mean when I'm only marking off the hundreds. I'm going up by increments of 100.
So when someone asks you to round to the nearest hundred, they're literally saying round to one of these increments of 100 or round to whichever increment of 100 that it is closest to. And if you look at it right like this, if you just eyeball it, you'll actually see that it is closer to 24,300 than it is to 24,200. So when you round it, you round to 24,300.
And so rounding up in this situation, it is 5. It is 5 or greater, so rounding up means that we go to 24,000, and since we're rounding up, we make the 2 into a 3. We increment it by one, so rounding up, so 24,300.
And when you round down, be careful. It doesn't mean you decreases this 2. It literally means you just only have the 2.
24,249 is going to be sitting right over here someplace, so it's going to be closer to 24,200. 24,200 would be the nearest hundred when we round down in this case. For the case of the problem, 24,259, the nearest hundred is 24,300.

Google Search is incredibly powerful. You can search for text across the Internet most of human knowledge, images, books, videos. But, we realized there was an important part of the Search experience that we'd overlooked.
-We're excited to announce Google NoseBeta our flagship olfactory knowledge feature enabling users to search for smells. Our mobile aroma indexing program has been able to amass a 15 million scentibite database of smells from around the world.
-With an elegant integration into our existing knowledge panels, the Google Nose Beta Smell button seamlessly connects scent to search. By intersecting photons with infrasound waves,
Google Nose Beta temporarily aligns molecules to emulate a particular scent.
Google Nose Beta works on nearly all desktops, laptops, and quite a few mobile devices. In the fast paced world that we live in, we don't always have time to stop and smell the roses.
"what does a new car smell like?", who knows the answer?
Google Nose. -What does a ghost smell like?
Google Nose. What does the inside of an Egyptian tomb smell like?
Google Nose.
Google Nose.
Google Nose...Beta.
And 17 is a prime number so it's not going to share any common factors with 40, or at least 40 isn't divisible by 17 either, so this is as simplified as we can get.
So this part, the [integer] part, is 3 and the fraction part is 17/40. And we're done And this worked.
Hello. We are now gonna do some slope and y intercept problems as well. y-intercept problems as well. Let's get started.
OK. And then let me graph negative three, negative three. So it's one, two, three.
That's my new technique. I draw it in two pieces. I think that's good enough.
So change in y could be five-- remember, y is the second coordinate-- five minus negative three. And that's this one. Over-- now you do the change in x-- two minus, this is also negative three.
And let's count how far that is. Well, it's one, two, three, four, five units. So we can say delta x is equal to five.
OK. There you go. Good line.
Change in y over change in x. Let's take this y as the first point now. So we'll say five minus this y, negative three.
And actually what we'll do is we'll leave off here, and I'm going to solve for b-- and you could try to do it on your own-- in the next installment of this presentation.
Could you speculate a little bit about how a company like Facebook could use information about things like users clicking on a like button on something to suggest possibly people to be friends with?
[Tina] Right. A simple way is this idea that --
The egonet is the network that connects the ego to the alters and that connects the alters together. You can have egonets that look like a star where you have the ego and the alters, but none of the alters know each other. Or you can have a clique where everybody knows each other in this egonet.
Let's talk about exactly how oxygen and carbon dioxide come into and out of the lung.
So you know this is our alveolus in the lungs. This is the last little chamber of air where the lungs are going to interface with blood vessels.
So this is our blood vessel down here. Oxygen is going to make its way from this alveolus into the blood vessel.
It's going to from from the blood vessel into a little red blood cell. This is my red blood cell here.
They lived in a world where image had become everything So you're saying this season, purple is the new yellow? How fabulous!
Contagious is a good word.
Even in the times of H1N1, I like the word. Laughter is contagious. Passion is contagious.
"I Can" bug. So, the question is, why only them? In a country of a billion people and some, why so few?
And look at Ragav, that moment when his face changes because he's been able to understand that he has shifted that man's mindset. And that can't happen in a classroom.
So, when Ragav experienced that he went from "teacher told me," to "I am doing it." And that's the "I Can" mindshift.
And it is a process that can be energized and nurtured. But we had parents who said,
"Okay, making our children good human beings is all very well, but what about math and science and English? Show us the grades." And we did.
Since 2007 every other month the city closes down the busiest streets for traffic and converts it into a playground for children and childhood. Here was a city telling its child, "You can." A glimpse of infection in Ahmedabad.
[Unclear] So, the busiest streets closed down. We have the traffic police and municipal corporation helping us.
(Music)
(Music) Kiran Bir Sethi: And the city will give free time.
(Music)
KBS: And because of that, Ahmedabad is known as India's first child-friendly city.
First time, a rally and a street play in a rural school -- unheard of -- to tell their parents why literacy is important.
Look at what their parents says. Man: This program is wonderful.
KBS: An inner city school in Hyderabad. Girl:
581. This house is 581 ... We have to start collecting from 555.
Girls and boys in Hyderabad, going out, pretty difficult, but they did it.
Woman: Even though they are so young, they have done such good work. First they have cleaned the society, then it will be Hyderabad, and soon India.
KBS: So, the charter of compassion starts right here. Street plays, auctions, petitions.
70 years ago, it took one man to infect an entire nation with the power of "We can."
So, today who is it going to take to spread the infection from 100,000 children to the 200 million children in India? Last I heard, the preamble still said, "We, the people of India," right? So, if not us, then who?
(Applause)
Where the product goes and see the box labeled value proposition. As was simulated, the value proposition includes all the features of your product but also the pains and gains you're solving for the customer segment and that's where the market goes. The market includes where your customers are and what problems you're solving for them.
The next piece is who are your key partners and suppliers. Partnerships are kind of interesting is we need to ask ourselves before what's the deal is what exactly are we acquiring from partners, and also what activities are they going to perform and when. And this is where a start up sometimes make a mistake of thinking while large companies do partnerships, I guess I need those two on day 1.
I'm Michael Shermer, director of the Skeptics Society, publisher of "Skeptic" magazine.
We investigate claims of the paranormal, pseudo-science, fringe groups and cults, and claims of all kinds between, science and pseudo-science and non-science and junk science, voodoo science, pathological science, bad science, non-science, and plain old non-sense. And unless you've been on Mars recently, you know there's a lot of that out there. Some people call us debunkers, which is kind of a negative term.
We are like the bunko squads of the police departments out there -- well, we're sort of like the Ralph Naders of bad ideas, (Laughter) trying to replace bad ideas with good ideas. I'll show you an example of a bad idea. I brought this with me, this was given to us by NBC Dateline to test.
(Laughter) Well, it has kind of a right-leaning bias. Well, this is science, so we'll do a controlled experiment.
Sir, do you want to empty your pockets, please, sir? (Laughter) So the question was, can it actually find marijuana in students' lockers?
So that's just a fun little example here of the sorts of things we do. "Skeptic" is the quarterly publication. Each one has a particular theme.
What's the more likely explanation? Before we say something is out of this world, we should first make sure that it's not in this world. What's more likely: that Arnold had extraterrestrial help in his run for the governorship, or that the "World Weekly News" makes stuff up?
(Laughter) The same theme is expressed nicely here in this Sidney Harris cartoon. For those of you in the back, it says here:
So again, we can ask this: what's more likely? Are UFOs alien spaceships, or perceptual cognitive mistakes, or even fakes? This is a UFO shot from my house in Altadena, California,
"I have observed that the furthest planet has three bodies." And this is what he ended up concluding that he saw. So without a theory of planetary rings and with only grainy data, you can't have a good theory.
The Virgin Mary? (Laughter) It has that sort of puckered lips, 1940s-era look.
So is it really a miracle of Mary, or is it a miracle of Marge? (Laughter) And now I'm going to finish up with another example of this, with auditory illusions.
(Music ends) Couldn't you just listen to that all day?
All right, here it is backwards, and see if you can hear the hidden messages that are supposedly in there.
What did you get? Audience: Satan!
(Music ends) (Laughter) (Applause) You can't miss it when I tell you what's there. (Laughter)
I'm going to just end with a positive, nice little story. The Skeptics is a nonprofit educational organization. We're always looking for little good things that people do.
In America it'd be, "We're 6,000 light years from the edge." (Laughter) But my friend, Simon Singh, the particle physicist now turned science educator, who wrote the book "The Big Bang," and so on, uses every chance he gets to promote good science.
How cool is that?
The mistakes that occurred because one wants others to do the way he wills Let's do [a samayik] on this - making others do the way we want (dharyu karavanu). We already did some analysis on this, just now. ... are we hurting others because we want them to do the way we will?
What is the reason for wanting to get our way (dharyu)? From our viewpoint we believe that ours is the truth and we want to force this truth onto others. And if the other person doesn't accept it, we use pressure and overt insistence (aagraha) to make that person do what we want.
And then what is the problem with the inferior and superior [complexities]? When the superior get's his way all the time and the inferior [complexity] can't have his way, then he becomes suppressed. And when the time comes he overturns the other person [with the superior complexity] and struggles to get his own way.

My topic is economic growth in China and India. And the question I want to explore with you is whether or not democracy has helped or has hindered economic growth. You may say this is not fair, because I'm selecting two countries to make a case against democracy.
"Which is China and which is India, and which country has grown faster?" if you believe in the infrastructure view, then you will say, "Country 1 must be China. They must have done better, in terms of economic growth. And Country 2 is possibly India."
"Which are the two Asian countries? And which one is a democracy?" you may argue,
"Well, maybe Country A is China and Country B is India." In fact, Country A is democratic India, and Country B is Pakistan -- the country that has a long period of military rule. And it's very common that we compare India with China.
"Have you won the lottery?" And they all tell you, "Yes, we have won the lottery." And then you draw the conclusion the odds of winning the lottery are 100 percent.
Life expectancies: as early as 1965, China had a huge advantage in life expectancy. On average, as a Chinese in 1965, you lived 10 years more than an average Indian.
OSHO OSHO TALKS: silence shared in words OSHO International Foundation presents
Let's take a look at the answer about which intellectual property matched what is protectable in examples. For trademark, what is protectable is branding. Examples are marks and logos and slogans.
Paulo wants to earn $1500 by mowing lawns. He will charge $35 for each lawn he mows. What is the minimum number of lawns the Paulo needs to mow to reach his goal of $1500?
Now 35 does not go into 1, so we have to add another digit.
35 does not go into 15.
35 goes into 150. Well, 30 goes into 150 five times.
35 is bigger so it won't go into it five times.
Let's try out 4. Let's see if it goes into it four times.
4 times 5 is 20. Let's regroup the 2, or carry the 2. Four times 3 is 12.
12 plus 2 is 14. Now we subtract.
0 minus 0 is 0.
5 minus 4 is 1. The ones cancel out, and then we bring down this zero right here.
35 goes into 100. Well, 35 times 2 is 70, and if you add another-- 35 times 3 is 105, so that's too big, so it goes into it two times. 2 times 5 is 10.
2 times 3 is 6 plus 1 is 7, or 35 times 2 is 70. You subtract.
0 minus 0 is 0.
0 minus 7, you can't do it. You could already view it as 10 minus 7, or if you want to go in the traditional way, this 0 can take or borrow 1 from this 1, so that becomes a 0. This becomes a 10.
10 minus 7 is 30. And so there's nothing left to bring down. so we now know that 35 goes into 1,500 forty-two times, but there's a remainder of 30. If he mowed 42 lawns, he'd be 30 short of 1,500.
35 times 42 is 30 less than 1,500. What would it be?
1,470. So in order to make 1,500, he's going to have to go over it, so he's going to have to do one more lawn than this. So just to remind ourselves, if we just divide-- let me write it here.
1,500 divided by 35 is equal to 42, remainder 30, so 42 won't be enough lawns. We're going to have more to-- we have 30 more bucks to earn, so he's going to have to mow one more lawn to get another $35, so he's going to have $5 left over after he makes up this 30. So he's going to have to mow 43 lawns if he really wants to cross this threshold of $1500.
Let me just remind you the reason why I love this lecture is that there is a series of common mistakes that first time an even experienced entrepreneurs make in thinking about revenue and pricing. And the first one is that this whole idea about revenue stream, Steve, I get it. You know, revenue stream.
- no one would pay any more than the existing incumbents. And we're going to see that's another going out of business strategy. And all this depends on your knowledge that you've just learned about the customers, their reaction to the value proposition and all the work you've been doing outside the building.

Swapping out my pre-burned SlM cards everyday at 6pm is a small price to pay.
I don't care about privacy. or social status or accumulating stuff.
I don't care about the law or who makes it.
I live by one rule: information should be free.
And everything can be simplified, encoded and understood as information.
We call this the information age for a reason.
Companies and governments don't get it, so they are powerless against me.
You think there are rules?
You treat computers like you do everything else... ...like it's an immutable fact of life and because of that... ...your worldview is antiquated.

The interesting thing about the customer development process ties back into agile engineering and agile development hand and glove. Basically it's this notion of the minimum viable product. Back in the old days what we used to do is specify the entire feature set of the product from beginning to end.
"Steve Jobs didn't build the iPhone by asking customers." And we really doubt Henry Ford asked customers do they want a car before one existed. In fact, in his case if you would have asked people about what they wanted they would have said a faster horse or one with 6 legs.
Carving candles is an old German craft still practiced by artisans. It involves layering different colored wax Then carving designs to expose those luminous colors.
I wrote a letter last week talking about the work of the foundation, sharing some of the problems. And Warren Buffet had recommended I do that -- being honest about what was going well, what wasn't, and making it kind of an annual thing. A goal I had there was to draw more people in to work on those problems, because I think there are some very important problems that don't get worked on naturally.
So we can see: 1900, it's everywhere. 1945, it's still most places.

In the last video we went over the multiplication tables for one through nine and I ran out of time, and actually, it was a good thing because one through nine are kind of the core multiplication tables. And you'll see that if you know all your multiplication tables from one to nine, so you know any number between one and nine times any other number between one and nine, you can actually do any multiplication problem out there. But what I want to do now is I want to complete the multiplication tables for ten, eleven, and twelve.
Ten times zero. Anything times zero is zero. Ten zeros are zero.
Zero plus zero plus zero ten times is still zero. What's ten times one? Ten times one.
What's ten times two?
Ten times two. I meant to switch colors, but I didn't.
Ten times two? That's ten plus ten, which is twenty. Fair enough.
What's ten times three?
Well, that's ten plus ten plus ten, or we could view it as ten times two plus another ten, which is equal to thirty. What's ten times four? I think you start to see a pattern.
Ten times four is equal to forty. Notice, ten times four is equal to forty. If I were to ask you what is ten times--
Ten times anything is that anything with a zero behind it. So the ten times tables, you almost don't have to remember it. So let's just keep going.
What's ten times six? It's equal to sixty.
Six zero.
What's ten times seven?
Seventy. Ten times eight? This is almost ridiculous.
Ten times eight is eighty.
Ten times nine?
Ninety.
Ten times ten? Now this is interesting.
Ten times ten, so it'll be a ten-- let's see me write this. Let me do it in this orange color.
Ten times ten. So it'll be ten tens or a ten with a zero behind it. There you go.
Notice, whatever number times ten, I just add a zero, then I get the next number. So it's one hundred. And I think you understand why that is.
Thirty is just three tens or ten times three.
Ninety is just nine tens or nine times ten. Let's keep going. So ten times eleven is equal to eleven with a zero behind it.
One hundred and ten. Finally, ten times twelve is equal to one hundred and twenty. Now, just for fun, these are kind of your ten times tables.
Five seven three two with a zero behind it. And just so you know, this little comma that I wrote in the number there, that's just to make it easier for me to read that number. So, you put the comma-- you start over here and every third number you put the comma.
So, eleven times zero. This is easy, this is zero!
Eleven times one. This is also easy! It's eleven!
Eleven times two. We're going to start seeing a pattern here. It's eleven plus eleven or we could've added two to itself eleven times, but that is equal to twenty-two.
Eleven times four is equal to forty-four. I think this is becoming obvious to you.
What's eleven times five?
Eleven times five is fifty-five! Notice I put the five twice.
What's eleven times six? It's sixty-six!
Eleven times seven is eighty-four-- no! I'm kidding! I didn't want to mess with you like that.
Seventy-seven. You just repeat the number twice.
Seventy-seven. Let me switch colors.
Eleven times eight is equal to eighty-eight.
Eleven times nine is equal to ninety-nine!
Eleven times twelve. Oh sorry, I skipped ten.
Eleven times ten. You might want to say it's "tenty-ten!" No!
Eleven times ten-- well, we could think about it a couple of ways. We can add eleven to ninety-nine. So we can say it's ninety-nine plus eleven.
Eleven times twelve. No easy way to remember this, you just kind of should remember it. Or you could say look, it's going to be eleven more than eleven times-- sorry.
Eleven plus one hundred ten is one hundred twenty-one. And actually, as you'll see, there actually is an order as we get to higher multiples of eleven, but I'll leave that to a future video. And then finally, we're at eleven times twelve.
Eleven times twelve. And we could add eleven to itself twelve times. We could add twelve to itself eleven times.
Ten times twelve, we already knew that. That was one hundred twenty. So eleven times twelve, because we're multiplying twelve by one more should be twelve more than that.
Twelve times tables. And once you know this you are ready to tackle any type of multiplication problem. But we'll do that in future videos.
Zero.
Twelve times one. Also super easy!
Is twelve. Now it gets interesting. We're going to increase by twelve every time.
Twelve times-- not twenty-two. Let me rewrite that.
Twelve times three is going to be twelve plus twelve plus twelve. Or we could write that as twelve times two. I see my brain is doing the wrong things.
Twelve times four.
Twelve times four is equal to forty-eight. There's a lot of ways you could think about it. You could say eleven times four is forty-four.
Twelve times five is equal to sixty.
Ten times five is fifty, eleven times five is fifty-five, so twelve times five is sixty!
Twelve times six is equal to what? It's going to be twelve more than this. It's going to be equal to seventy-two.
Twelve times seven. Twelve more than this again.
Twelve more than seventy-two is eighty-four. And I'm serious, you know, I'm probably a lot older than you are, and I still, in my head to confirm, I go to some twelve times tables that I remember as definitely right.
Twelve times six is seventy-two. All right. Then you go to twelve times eight.
Add twelve to the twelve times seven.
Ninety-six.
Twelve times nine. Well you add twelve to this, so it's one hundred eight.
One hundred eight. And then twelve times ten. This is an easy one!
We just add a zero to the twelve to get one hundred twenty. Or we could've added twelve to one hundred eight. Either way.
Twelve times eleven. We just did this. You add twelve to this to get one hundred thirty-two.
What is eleven times eleven? And you should quiz each other, because it'll pay huge rewards to you later on in life. See you in the next video!
So let's take a quick moment and talk about something else that's very important to game development: what format your images are in? Now typically on the internet when you find photos or pictures of cats just floating around on random web pages, it's actually in a JPEG format. JPEG was developed some time ago by a joint efforts group from some of the industry's largest contributors.
JPEG itself gives you better compression formats but doesn't allow you to use transparent pixels in your scene, which means the general rule of thumb is if you have an image on the internet that doesn't require it to be transparent you should probably be using JPEG. If it requires alpha you need to be using PNG. Now the cool thing about the internet is that it's always moving forward and new technologies are being developed every day to make the experience for end users better.
Besides JPEG and PNG, there's a new image format coming down the pipe called
WebP.
WebP offers and interesting ground. First off, it has compression ratios similar if not better in some cases than JPEG but also allows you to have alpha transparency supported by PNG. Therefore we have with this new image format the ability to get good compression and alpha transparency where we need it.
For emotions, we should not move quickly to the desert. So, first, a small housekeeping announcement: please switch off your proper English check programs installed in your brain. (Applause)

One day, she takes the train an hour early and arrives at 5:00. Her husband leaves home to meet her at the same usual time. Husband leaves home to meet her at the usual time.
If t is 30 minutes, it would be 5:30. If t is one hour, it would be 5 o'clock. So leaves at 6 o'clock minus t.
This time she started walking because she got there early, and he gets there 10 minutes-- he reaches her 10 minutes earlier than he normally would have reached her, right? t minus 10. Normally, he reaches her at 6 o'clock. Today he reaches her 10 minutes earlier.
So he reaches her at 5:50. Now, the question is, how many minutes did Bev walk? How many minutes did Bev walk?
She arrives at 5:00, 5 o'clock, and just starts walking. And when does he pick her up? He picks her up at 5:50.
So she walked for 50 minutes. That's a neat problem. Because on some level, it's very easy, but on a lot of other levels, they give you all of this other information that's not necessary.
Hi. This is ajay This is Aneesh
Use the commutative law of multiplication to write 2 times 34 in a different way. Simplify both expressions to show that they have identical results. So once again, this commutative law just means that order doesn't matter.
But let's do it this way. 4 times 2 is 8, and then we'll put a 0.
3 times 2 is 6, or you can view it as 30 times 2 is 60.
Add them together. 8 plus 0 is 8.
6, bring it down. It's not being added to anything. You get 68.
So we have this rectangle right over here, we call it, the length of AB is equal to 1 So that's labeled right over there, AB is equal to 1 And they tell us that BE and BD trisect angle ABC
What they want us to figure out is, what is the perimeter of triangle BED, triangle BED So it's kinda this middle triangle and the rectangle right over here So at first it seems like a pretty hard problem, because you're like, what is the width of this rectangle how can I start on this, they've given only one side here
And so one thing we do know that, the opposite sides of a rectangle are the same length This side is 1, then this side over there is 1 The other thing we know is that this angle is trisected
Rewrite the expression five times 9 minus 4-- that's in parentheses-- using the distributive law of multiplication over subtraction. Then simplify. So let me just rewrite it.
Let's just take a look at the last piece which is why you're here. How do we teach entrepreneurship? Well, in the past, entrepreneurial education was about execution.
Well, if you look at the Amazon website and now that you can go AWS but just a traditional bookselling website, you'll find that all of these things are part of their product. The website for allowing users to find and buy products, a review system and rating system for products, protection against fraud for marketplace sellers, and the content itself--movies, books, music, etc. The sum of all these are what makes up Amazon's complete product.
For painters, a tint is a color plus white.
A shade is a color plus black

What I want to do in this video is establish a reasonably powerful condition in which we can establish that at vector field, or that a line integral of a vector field is path independent. And when I say that, I mean that let's say I were to take this line integral along the path c of f dot d r, and let's say my path looks like this.
That's my x and y axis, and let's say my path looks something like this: I start there and I go over there to point c. My end point, the curve here is c.
And I'm not going to prove it in this video, but I think it'll be pretty intuitive for you. So maybe it doesn't need to have a proof, or I'll prove it eventually, but I really just want to give you the intuition. And all that says is that if I have some function-- let's say

CHAPTER I. One morning, as Gregor Samsa was waking up from anxious dreams, he discovered that in bed he had been changed into a monstrous verminous bug. He lay on his armour-hard back and saw, as he lifted his head up a little, his brown, arched abdomen divided up into rigid bow- like sections.
Above the table, on which an unpacked collection of sample cloth goods was spread out--Samsa was a travelling salesman--hung the picture which he had cut out of an illustrated magazine a little while ago and set in a pretty gilt frame. It was a picture of a woman with a fur hat and a fur boa. She sat erect there, lifting up in the direction of the viewer a solid fur muff into which her entire forearm had disappeared.
But that would be extremely embarrassing and suspicious, because during his five years' service Gregor hadn't been sick even once. The boss would certainly come with the doctor from the health insurance company and would reproach his parents for their lazy son and cut short all objections with the insurance doctor's comments; for him everyone was completely healthy but really lazy about work. And besides, would the doctor in this case be totally wrong?
"I'm coming right away," said Gregor slowly and deliberately and didn't move, so as not to lose one word of the conversation. "My dear lady, I cannot explain it to myself in any other way," said the manager;
"I hope it is nothing serious. On the other hand, I must also say that we business people, luckily or unluckily, however one looks at it, very often simply have to overcome a slight indisposition for business reasons." "So can Mr. Manager come in to see you now?" asked his father impatiently and knocked once again on the door.
"But Mr. Manager," called Gregor, beside himself and, in his agitation, forgetting everything else, "I'm opening the door immediately, this very moment. A slight indisposition, a dizzy spell, has prevented me from getting up. I'm still lying in bed right now.
"For God's sake," cried the mother already in tears, "perhaps he's very ill and we're upsetting him.
Grete!" she yelled at that point. "Mother?" called the sister from the other side. They were making themselves understood through Gregor's room.
"fetch a locksmith right away!" The two young women were already running through the hall with swishing skirts--how had his sister dressed herself so quickly?- -and yanked open the doors of the apartment. They probably had left them open, as is customary in an apartment where a huge misfortune has taken place.
In addition to all this, she put down a bowl--probably designated once and for all as Gregor's--into which she had poured some water. And out of her delicacy of feeling, since she knew that Gregor would not eat in front of her, she went away very quickly and even turned the key in the lock, so that Gregor would now observe that he could make himself as comfortable as he wished. Gregor's small limbs buzzed now that the time for eating had come.
In the midst of minor attacks of asphyxiation, he looked at her with somewhat protruding eyes, as his unsuspecting sister swept up with a broom, not just the remnants, but even the foods which Gregor had not touched at all, as if these were also now useless, and as she dumped everything quickly into a bucket, which she closed with a wooden lid, and then carried all of it out of the room. She had hardly turned around before Gregor had already dragged himself out from the couch, stretched out, and let his body expand. In this way Gregor got his food every day, once in the morning, when his parents and the servant girl were still asleep, and a second time after the common noon meal, for his parents were, as before, asleep then for a little while, and the servant girl was sent off by his sister on some errand or other.
Grete had placed her arm around her mother and held her tightly. "So what shall we take now?" said Grete and looked around her. Then her glance met Gregor's from the wall.
Grete's purpose was clear to Gregor: she wanted to bring his mother to a safe place and then chase him down from the wall. Well, let her just try! He squatted on his picture and did not hand it over.
Grete's appearance had told him everything. Grete replied with a dull voice; evidently she was pressing her face into her father's chest: "Mother fainted, but she's getting better now.
From the fruit bowl on the sideboard his father had filled his pockets. And now, without for the moment taking accurate aim, he was throwing apple after apple. These small red apples rolled around on the floor, as if electrified, and collided with each other.
Grete," and when Gregor was again in the darkness, while close by the women mingled their tears or, quite dry eyed, stared at the table. Gregor spent his nights and days with hardly any sleep. Sometimes he thought that the next time the door opened he would take over the family arrangements just as he had earlier.
"Perhaps the gentlemen don't like the playing? It can be stopped at once."
"On the contrary," stated the lodger in the middle, "might the young woman not come into us and play in the room here, where it is really much more comfortable and cheerful?"
"Oh, thank you," cried out the father, as if he were the one playing the violin. The men stepped back into the room and waited. Soon the father came with the music stand, the mother with the sheet music, and the sister with the violin.
"She is right in a thousand ways," said the father to himself. The mother, who was still incapable of breathing properly, began to cough numbly with her hand held up over her mouth and a manic expression in her eyes. The sister hurried over to her mother and held her forehead.
"he's already starting up again." With a fright which was totally incomprehensible to Gregor, the sister even left the mother, pushed herself away from her chair, as if she would sooner sacrifice her mother than remain in Gregor's vicinity, and rushed behind her father who, excited merely by her behaviour, also stood up and half raised his arms in front of the sister as though to protect her.
"Come and look. It's kicked the bucket. It's lying there, totally snuffed!"
The Samsa married couple sat upright in their marriage bed and had to get over their fright at the cleaning woman before they managed to grasp her message. But then Mr. and Mrs. Samsa climbed very quickly out of bed, one on either side. Mr. Samsa threw the bedspread over his shoulders, Mrs. Samsa came out only in her night-shirt, and like this they stepped into Gregor's room.
Grete, who did not take her eyes off the corpse, said, "Look how thin he was. He had eaten nothing for such a long time. The meals which came in here came out again exactly the same."
Grete went, not without looking back at the corpse, behind her parents into the bed room. The cleaning woman shut the door and opened the window wide. In spite of the early morning, the fresh air was partly tinged with warmth.
Now that we know what an angle is, let's think about how we can measure them--and we already hinted at one way to think about the measure of an angle in the last video when we said: "Look, this angle XYZ seems more open than angle BAC so maybe the measure of angle XYZ should be larger than the angle of BAC", and that is exactly the way we think about the measures of angles, but what I want to do in this video is come up with an exact way to measure an angle. So what I've drawn over here is a little bit of a half circle, and it looks very similar to a tool that you can buy at your local school supply store to measure angles.
We have three different addition problems right over here... and what I want you to do (so you get the hang of things), is to pause the video and try them on your own. But as you do them, I want you to really keep in mind and think about what the carrying actually means. So I assume you've tried on your own, Now I'll work through them with you.
There are lots of important issues. But, the most important is, probably, repealing Obamacare. Erm, I think that's . . .it's not, not good.
Yes and. . . and no.
Erm,we just need change and better change. Not the kind of change that Obama brought. That's all.
Yes. It's been broken for a couple of years, now. Only a few, erm, remain that still actually have the country in mind and not their own selves.
So we're told that Minli has $5.00 more than James. Minli has $33.00.
How much does James have? So let's use some letters to represent the amount of money Minli has and the amount of money James has.
Recognizing Prime Numbers Determine whether the following numbers are prime, composite, or neither. Just as a bit of a review, a prime number is a natural number, so one of the counting numbers 1, 2, 3, 4, 5, 6, and so on, that has exactly two factors.
1 and 3. Another way to think about it is the only way to get 3 as a product of other natural numbers is 1 × 3. So it only has 1 and itself.
A composite number is a natural number that has more than just 1 and itself as factors and we'll see examples of that. And neither, we'll see an interesting case of that in this problem. First let's think about 24.
The non-zero whole numbers that are divisible into 2 1 × 2 definitely works, 1 and 2, but there really aren't any others that are divisible into 2. So it has only 2 factors, 1 and itself. That's a definition of a prime number.
So 2 is prime; every other even number other than 2 is composite. Here is an interesting case: 1.
In order to be composite you have to have more than two factors: 1, yourself, and some other things. So it's not composite.
I collaborate with bacteria. And I'm about to show you some stop-motion footage that I made recently where you'll see bacteria accumulating minerals from their environment over the period of an hour. So what you're seeing here is the bacteria metabolizing, and as they do so they create an electrical charge.
(Applause)
We've got a scale here, and as you see, the scale is balanced. And we have a question to answer. We have this mystery mass over here.
To figure out what this mystery mass is, we essentially just want this on one side of this scale But that by itself is not enough. We could just remove these three, but that won't do the job, because if we just remove these three, then the left side of this scale is clearly going to have less mass, and it will go up, and the right side will go down.
- and if we're assuming they are kilograms - we'll know that the question mark mass question mark is equal to 7 kilograms. So this is a seven kilogram mass.
The Worldly Life Is Perpetuated By illusionary Attachments Jai Sat Chit Anand Today, our subject for satsang - samayik is that of illusionary attachment (moha).
one has so much moha there... for one's own-self, for what one says one has a lot of moha for what one says [one believes] what one says is true, one holds on to one's own version of what he says, what one believes in, is right everything else besides that is wrong
So much [moha] for one's own speech There is a lot [of moha] for one's beliefs
And not only that, but that it [the belief] is correct one believes strongly that, "I am right" but not just that, when someone says that, "no, this is not right" then one will lose his coolness He will go out of his way to prove he is right he will not give up, [do whatever it takes] to prove he is right
one is right, what one believes in is right and one will not let anyone prove otherwise this [trait] is moha, moha for oneself Women hold on to their belief that "what they say is right", because of moha Moha for their own-self
if there is even a little bit of disturbance to their being, they make a mountain out of the molehill some have it [this behavior] in excess they pay too much attention to their own-self and even if they have endured a slight bit of suffering, they go on about it all day long "I have pain in my hips, this is happening to me, that is happening to me", They keep repeating this and intensifying the psychological effects persons with a mind-body complex of a Kshatriya (warrior caste) do not even remember anything
they do not care about any of that [the suffering they are feeling] they get up however they can, and just go about doing what needs to be done in the other case one will just keep soothing themselves, taking care of themselves this is the moha for one's own-self so now, one needs to give up all this [type of moha] all this is moha, everyone now needs to come out of this moha, there is so much excessive moha for one-self they argue, quarrels, abuse each other daily yet she cannot do without him if he is not there, she is does not like it it will not let non-attachment (vairaag) come about in some cases they are beaten up so badly, the husband is physically violent, consumes alcoholic, does not earn the wife earns and he takes her money and goes and gets drunk yet she cannot get detached from him the moha, makes her hold on it does not let vairaag come about it does not even let the thought that, "I want to go to moksha" arise It is no different for men moha for their wives no matter how much they may be harassed by them [their wives] But if she makes him a gourmet meal, then they are happy
It is because of this moha, that the worldly cycle of birth-rebirth is perpetuated Get married, expand the family, then die, then marry again, then die again, and repeat the same process again How much moha should one have for one's children?

Thanks very much. Good evening.
Good evening everyone.
Thanks so much.
So, is this what happens at the UN every Friday night? 'Cause... I gotta tell you...
If you're lucky maybe next friday they can book me again for this. [I Was Here - World Humanitarian Day August 19 whd-iwashere.org]
A few years ago, I felt like I was stuck in a rut, so I decided to follow in the footsteps of the great American philosopher, Morgan Spurlock, and try something new for 30 days. The idea is actually pretty simple. Think about something you've always wanted to add to your life and try it for the next 30 days.
"I'm a computer scientist." No, no, if I want to, I can say, "I'm a novelist." (Laughter)
CHAPTER I THERE IS NO ONE LEFT When Mary Lennox was sent to Misselthwaite Manor to live with her uncle everybody said she was the most disagreeable-looking child ever seen. It was true, too.
The Mem Sahib wrung her hands. "Oh, I know I ought!" she cried. "I only stayed to go to that silly dinner party.
"It is the child no one ever saw!" exclaimed the man, turning to his companions. "She has actually been forgotten!"
"Why was I forgotten?" Mary said, stamping her foot. "Why does nobody come?"
"I don't know anything about him," snapped Mary. "I know you don't," Basil answered. "You don't know anything.
Misselthwaite Manor, she looked so stony and stubbornly uninterested that they did not know what to think about her. They tried to be kind to her, but she only turned her face away when Mrs. Crawford attempted to kiss her, and held herself stiffly when Mr. Crawford patted her shoulder. "She is such a plain child," Mrs. Crawford said pityingly, afterward.
"Perhaps if her mother had carried her pretty face and her pretty manners oftener into the nursery Mary might have learned some pretty ways too. It is very sad, now the poor beautiful thing is gone, to remember that many people never even knew that she had a child at all."
"I believe she scarcely ever looked at her," sighed Mrs. Crawford. "When her Ayah was dead there was no one to give a thought to the little thing. Think of the servants running away and leaving her all alone in that deserted bungalow.
She was a stout woman, with very red cheeks and sharp black eyes.
"Perhaps she will improve as she grows older," the officer's wife said good- naturedly. "If she were not so sallow and had a nicer expression, her features are rather good. Children alter so much."
Misselthwaite Manor and the only way in which she could keep it was to do at once what Mr. Archibald Craven told her to do. She never dared even to ask a question. "Captain Lennox and his wife died of the cholera," Mr. Craven had said in his short, cold way.
(Marred is a Yorkshire word and means spoiled and pettish.) She had never seen a child who sat so still without doing anything; and at last she got tired of watching her and began to talk in a brisk, hard voice. "I suppose I may as well tell you something about where you are going to," she said.
"No," said Mary frowning. She frowned because she remembered that her father and mother had never talked to her about anything in particular. Certainly they had never told her things.
"You are right enough there," said Mrs. Medlock. "It doesn't. What you're to be kept at Misselthwaite Manor for I don't know, unless because it's the easiest way.
Houppe." It had been about a poor hunchback and a beautiful princess and it had made her suddenly sorry for Mr. Archibald Craven. "Yes, she died," Mrs. Medlock answered.
"I shall not want to go poking about," said sour little Mary and just as suddenly as she had begun to be rather sorry for Mr. Archibald Craven she began to cease to be sorry and to think he was unpleasant enough to deserve all that had happened to him. And she turned her face toward the streaming panes of the window of the railway carriage and gazed out at the gray rain-storm which looked as if it would go on forever and ever. She watched it so long and steadily that the grayness grew heavier and heavier before her eyes and she fell asleep. >
CHAPTER ill ACROSS THE MOOR She slept a long time, and when she awakened Mrs. Medlock had bought a lunchbasket at one of the stations and they had some chicken and cold beef and bread and butter and some hot tea.
Medlock was shaking her. "You have had a sleep!" she said. "It's time to open your eyes!
"I feel as if it might be the sea, if there were water on it," said Mary. "It sounds like the sea just now." "That's the wind blowing through the bushes," Mrs. Medlock said.
"What's expected of you, Mrs. Medlock," Mr. Pitcher said, "is that you make sure that he's not disturbed and that he doesn't see what he doesn't want to see." And then Mary Lennox was led up a broad staircase and down a long corridor and up a short flight of steps and through another corridor and another, until a door opened in a wall and she found herself in a room with a fire in it and a supper on a table. Mrs. Medlock said unceremoniously:
Misselthwaite I should never have been even one of th' under house-maids. I might have been let to be scullerymaid but I'd never have been let upstairs. I'm too common an' I talk too much Yorkshire.
Mr. Craven, he won't be troubled about anythin' when he's here, an' he's nearly always away. Mrs. Medlock gave me th' place out o' kindness. She told me she could never have done it if Misselthwaite had been like other big houses."
"Mrs. Medlock told me I'd have to be careful or you wouldn't know what I was sayin'. I mean can't you put on your own clothes?"
"No," answered Mary, quite indignantly. "I never did in my life. My Ayah dressed me, of course."
"Well," said Martha, evidently not in the least aware that she was impudent, "it's time tha' should learn. Tha' cannot begin younger. It'll do thee good to wait on thysen a bit.
"It is different in India," said Mistress Mary disdainfully. She could scarcely stand this. But Martha was not at all crushed.
"These are th' ones tha' must put on," Martha answered. "Mr. Craven ordered Mrs. Medlock to get 'em in London. He said 'I won't have a child dressed in black wanderin' about like a lost soul,' he said.
Misselthwaite Manor would end by teaching her a number of things quite new to her-- things such as putting on her own shoes and stockings, and picking up things she let fall. If Martha had been a well-trained fine young lady's maid she would have been more subservient and respectful and would have known that it was her business to brush hair, and button boots, and pick things up and lay them away. She was, however, only an untrained Yorkshire rustic who had been brought up in a moorland cottage with a swarm of little brothers and sisters who had never dreamed of doing anything but waiting on themselves and on the younger ones who were either babies in arms or just learning to totter about and tumble over things.
"Where did he get it?" asked Mary. "He found it on th' moor with its mother when it was a little one an' he began to make friends with it an' give it bits o' bread an' pluck young grass for it. And it got to like him so it follows him about an' it lets him get on its back.
Dickon's a kind lad an' animals likes him." Mary had never possessed an animal pet of her own and had always thought she should
"I don't want it," repeated Mary. "Eh!" said Martha. "I can't abide to see good victuals go to waste.
"Why?" said Mary coldly. "Why!" echoed Martha. "Because they scarce ever had their stomachs full in their lives.
"I don't know what it is to be hungry," said Mary, with the indifference of ignorance. Martha looked indignant. "Well, it would do thee good to try it.
My word! don't I wish Dickon and Phil an' Jane an' th' rest of 'em had what's here under their pinafores." "Why don't you take it to them?" suggested Mary.
"Well, if tha' doesn't go out tha'It have to stay in, an' what has tha' got to do?" Mary glanced about her. There was nothing to do.
There's Mrs. Medlock's bell ringing--I must run." After she was gone Mary turned down the walk which led to the door in the shrubbery. She could not help thinking about the garden which no one had been into for ten years.
Tha'rt too forrad." The bird put his tiny head on one side and looked up at him with his soft bright eye which was like a black dewdrop. He seemed quite familiar and not the least afraid.
"Doesn't tha' know? He's a robin redbreast an' they're th' friendliest, curiousest birds alive. They're almost as friendly as dogs--if you know how to get on with 'em.
"He's a conceited one," he chuckled. "He likes to hear folk talk about him. An' curious--bless me, there never was his like for curiosity an' meddlin'.
Tha'It be lonlier before tha's done," he said.
"Tha' an' me are a good bit alike," he said.
"To me?" said Mary, and she moved toward the little tree softly and looked up. "Would you make friends with me?" she said to the robin just as if she was speaking to a person. "Would you?"
"He has flown into the orchard--he has flown across the other wall--into the garden where there is no door!" "He lives there," said old Ben. "He came out o' th' egg there.
If he's courtin', he's makin' up to some young madam of a robin that lives among th' old rose-trees there." "Rose-trees," said Mary. "Are there rose-trees?"
"Tha' got on well enough with that this mornin', didn't tha'?" said Martha. "It tastes nice today," said Mary, feeling a little surprised her self. "It's th' air of th' moor that's givin' thee stomach for tha' victuals," answered
You go on playin' you out o' doors every day an' you'll get some flesh on your bones an' you won't be so yeller." "I don't play," said Mary. "I have nothing to play with."
Weatherstaff's robin redbreast, tilting forward to look at her with his small head on one side. "Oh!" she cried out, "is it you--is it you?" And it did not seem at all queer to her that she spoke to him as if she were sure that he would understand and answer her.
Th' doctors thought he'd go out o' his mind an' die, too. That's why he hates it. No one's never gone in since, an' he won't
Mother's a good-tempered woman but she gets fair moithered. The biggest ones goes out in th' cow-shed and plays there.
Dickon he doesn't mind th' wet. He goes out just th' same as if th' sun was shinin'. He says he sees things on rainy days as doesn't show when it's fair weather.
"No." "Can tha' read?"
"Yes." "Then why doesn't tha, read somethin', or learn a bit o' spellin'? Tha'st old enough to be learnin' thy book a good bit now."
In fact, there was no one to see but the servants, and when their master was away they lived a luxurious life below stairs, where there was a huge kitchen hung about with shining brass and pewter, and a large servants' hall where there were four or five abundant meals eaten every day, and where a great deal of lively romping went on when Mrs. Medlock was out of the way. Mary's meals were served regularly, and Martha waited on her, but no one troubled themselves about her in the least. Mrs. Medlock came and looked at her every day or two, but no one inquired what she did or told her what to do.
A broad window with leaded panes looked out upon the moor; and over the mantel was another portrait of the stiff, plain little girl who seemed to stare at her more curiously than ever. "Perhaps she slept here once," said Mary. "She stares at me so that she makes me feel queer."
"I thought perhaps it always rained or looked dark in England," Mary said. "Eh! no!" said Martha, sitting up on her heels among her black lead brushes.
"Nowt o' th' soart!" "What does that mean?" asked Mary seriously. In India the natives spoke different dialects which only a few people understood, so she was not surprised when Martha used words she did not know.
'Nowt o' th' soart' means 'nothin'-of-the- sort,'" slowly and carefully, "but it takes so long to say it. Yorkshire's th' sunniest place on earth when it is sunny. I told thee tha'd like th' moor after a bit.
"Could I ever get there?" asked Mary wistfully, looking through her window at the far-off blue. It was so new and big and wonderful and such a heavenly color. "I don't know," answered Martha.
"I like your mother," said Mary. "I should think tha' did," agreed Martha, polishing away. "I've never seen her," said Mary.
"He wouldn't like me," said Mary in her stiff, cold little way. "No one does." Martha looked reflective again.
The high, deep, blue sky arched over Misselthwaite as well as over the moor, and she kept lifting her face and looking up into it, trying to imagine what it would be like to lie down on one of the little snow- white clouds and float about. She went into the first kitchen-garden and found Ben Weatherstaff working there with two other gardeners.
Weatherstaff.
"Tha'll have to wait for 'em. They'll poke up a bit higher here, an' push out a spike more there, an' uncurl a leaf this day an' another that. You watch 'em."
"I am going to," answered Mary. Very soon she heard the soft rustling flight of wings again and she knew at once that the robin had come again. He was very pert and lively, and hopped about so close to her feet, and put his head on one side and looked at her so slyly that she asked Ben Weatherstaff a question.
"Are things stirring down below in the dark in that garden where he lives?" "What garden?" grunted Weatherstaff, becoming surly again.
"India is quite different from Yorkshire," Mary said slowly, as she thought the matter over. "I never thought of that.
Did Dickon and your mother like to hear you talk about me?"
"Why, our Dickon's eyes nearly started out o' his head, they got that round," answered Martha. "But mother, she was put out about your seemin' to be all by yourself like.
"I don't want a governess," said Mary sharply. "But mother says you ought to be learnin' your book by this time an' you ought to have a woman to look after you, an' she says: 'Now, Martha, you just think how you'd feel yourself, in a big place like that, wanderin' about all alone, an' no mother.
An' he says 'Tuppence', an' mother she began fumblin' in her pocket an' she says to me, 'Martha, tha's brought me thy wages like a good lass, an' I've got four places to put every penny, but I'm just goin' to take tuppence out of it to buy that child a skippin'-rope,' an' she bought one an' here it is." She brought it out from under her apron and exhibited it quite proudly. It was a strong, slender rope with a striped red and blue handle at each end, but Mary Lennox had never seen a skipping- rope before.
"You just try it," urged Martha, handing her the skipping-rope. "You can't skip a hundred at first, but if you practice you'll mount up. That's what mother said.
P'raps tha' art a young 'un, after all, an' p'raps tha's got child's blood in thy veins instead of sour buttermilk. Tha's skipped red into thy cheeks as sure as my name's Ben Weatherstaff. I wouldn't have believed tha' could do it."
The sun was shining inside the four walls and the high arch of blue sky over this particular piece of Misselthwaite seemed even more brilliant and soft than it was over the moor. The robin flew down from his tree-top and hopped about or flew after her from one bush to another. He chirped a good deal and had a very busy air, as if he were showing her things.
"Two pieces o' meat an' two helps o' rice puddin'!" she said. "Eh! mother will be pleased when I tell her what th' skippin'-rope's done for thee." In the course of her digging with her pointed stick Mistress Mary had found herself digging up a sort of white root rather like an onion.
Eh! they are nice. Dickon's got a whole lot of 'em planted in our bit o' garden." "Does Dickon know all about them?" asked
"Do bulbs live a long time? Would they live years and years if no one helped them?" inquired Mary anxiously. "They're things as helps themselves," said Martha.
"I wish the spring was here now," said Mary. "I want to see all the things that grow in England." She had finished her dinner and gone to her favorite seat on the hearth-rug.
"How much would a spade cost--a little one?" Mary asked. "Well," was Martha's reflective answer, "at Thwaite village there's a shop or so an' I saw little garden sets with a spade an' a rake an' a fork all tied together for two shillings.
"I've got more than that in my purse," said Mary. "Mrs. Morrison gave me five shillings and Mrs. Medlock gave me some money from Mr. Craven."
"My word! that's riches," said Martha.
"Tha' can buy anything in th' world tha' wants. Th' rent of our cottage is only one an' threepence an' it's like pullin' eye-teeth to get it. Now I've just thought of somethin'," putting her hands on her hips.
"In the shop at Thwaite they sell packages o' flower-seeds for a penny each, and our
Dickon he knows which is th' prettiest ones an' how to make 'em grow. He walks over to Thwaite many a day just for th' fun of it. Does tha' know how to print letters?" suddenly.
If tha' could print we could write a letter to him an' ask him to go an' buy th' garden tools an' th' seeds at th' same time."
"Oh! you're a good girl!" Mary cried. "You are, really!
"I've got some of my own," said Martha. "I bought 'em so I could print a bit of a letter to mother of a Sunday.
He's a great friend o' Dickon's," said Martha. "How shall I get the things when Dickon buys them?" "He'll bring 'em to you himself.
"Does tha' want to see him?" asked Martha suddenly, for Mary had looked so pleased. "Yes, I do. I never saw a boy foxes and crows loved.
"If I went I should see your mother as well as Dickon," said Mary, thinking it over and liking the idea very much. "She doesn't seem to be like the mothers in India."
"Tha' mustn't go walkin' about in corridors an' listenin'. Mr. Craven would be that there angry there's no knowin' what he'd do."
"I wasn't listening," said Mary. "I was just waiting for you--and I heard it. That's three times."
Weatherstaff. "Makin' up to th' women folk just for vanity an' flightiness. There's nothin' he wouldn't do for th' sake o' showin' off an' flirtin' his tail- feathers.
"I think it's about a month," she answered. "Tha's beginnin' to do Misselthwaite credit," he said.
"Tha's a bit fatter than tha' was an' tha's not quite so yeller. Tha' looked like a young plucked crow when tha' first came into this garden. Thinks I to myself I never set eyes on an uglier, sourer faced young 'un."
"Oh! look at him!" exclaimed Mary. The robin was evidently in a fascinating, bold mood. He hopped closer and closer and looked at Ben Weatherstaff more and more engagingly.
"If you had one," said Mary, "what would you plant?" "Cabbages an' 'taters an' onions." "But if you wanted to make a flower garden," persisted Mary, "what would you plant?"
They run wild, but they was in rich soil, so some of 'em lived."
"When they have no leaves and look gray and brown and dry, how can you tell whether they are dead or alive?" inquired Mary. "Wait till th' spring gets at 'em--wait till th' sun shines on th' rain and th' rain falls on th' sunshine an' then tha'll find out."
"How--how?" cried Mary, forgetting to be careful. "Look along th' twigs an' branches an' if tha' see a bit of a brown lump swelling here an' there, watch it after th' warm rain an' see what happens." He stopped suddenly and looked curiously at her eager face.
"Well," said Ben Weatherstaff slowly, as he watched her, "that's true. Tha' hasn't." He said it in such an odd way that Mary wondered if he was actually a little sorry for her.
Tha'rt th' worst wench for askin' questions I've ever come a cross. Get thee gone an' play thee. I've done talkin' for today."
There's a little spade an' rake an' a fork an' hoe.
There's a trowel, too. An' th' woman in th' shop threw in a packet o' white poppy an' one o' blue larkspur when I bought th' other seeds." "Will you show the seeds to me?"
He untied the string and inside there were ever so many neater and smaller packages with a picture of a flower on each one. "There's a lot o' mignonette an' poppies," he said. "Mignonette's th' sweetest smellin' thing as grows, an' it'll grow wherever you cast it, same as poppies will.
Dickon. "Do you think he is?" cried Mary eagerly. She did so want to know.
"He wouldn't come near thee if he didn't," answered Dickon. "Birds is rare choosers an' a robin can flout a body worse than a man. See, he's making up to thee now.
Dickon's grin spread until he seemed all wide, red, curving mouth, and he rubbed his rough head. "I think I do, and they think I do," he said. "I've lived on th' moor with 'em so long.
Dickon said. It was true that she had turned red and then pale.
Dickon saw her do it, and as she still said nothing, he began to be puzzled. "Wouldn't they give thee a bit?" he asked. "Hasn't tha' got any yet?"
Dickon looked more puzzled than ever and even rubbed his hand over his rough head again, but he answered quite good- humoredly. "I'm keepin' secrets all th' time," he said. "If I couldn't keep secrets from th' other lads, secrets about foxes' cubs, an' birds' nests, an' wild things' holes, there'd be naught safe on th' moor.
Dickon's curious blue eyes grew rounder and rounder. "Eh-h-h!" he said, drawing his exclamation out slowly, and the way he did it meant both wonder and sympathy. "I've nothing to do," said Mary.
Dickon followed her with a queer, almost pitying, look on his face. He felt as if he were being led to look at some strange bird's nest and must move softly. When she stepped to the wall and lifted the hanging ivy he started.
Dickon looked round and round about it, and round and round again. "Eh!" he almost whispered, "it is a queer, pretty place! It's like as if a body was in a dream." >
What's the vision for Khan Academy in 10 years? We're at 5, 7 milion, you know reaching to bilion beyond classrooms everywhere. Bilion?
What I'm going to attempt to do in the next two videos is really just give an overview of everything that's happened to Earth since it came into existence. We're going start really at the formation of Earth or the formation of our Solar system or the formation of the Sun, and our best sense of what actually happened is that there was a supernova in our vicinity of the galaxy, and this right here is a picture of a supernova remnant, actually, the remnant for Kepler's supernova. The supernova in this picture actually happened four hundred years ago in 1604, so right at the center a star essentially exploded and for a few weeks was the brightest object in the night sky, and it was observed by Kepler and other people in 1604, and this is what it looks like now.
"planetesimals," which are, kinda view them as seeds of planets or early planets, and then those would have a reasonable amount of gravity and other things would be attracted to them and slowly clump up to them. This wasn't like a simple process, you know, you could imagine you might have one planetesimal form, and then there's another planetesimal formed, and instead of having a nice, gentle those two guys accreting into each other, they might have huge relative velocities and ram into each other, and then just, you know, shatter, so this wasn't just a nice, gentle process of constant accretion. It would actually have been a very violent process, actually happened early in Earth's history, and we actually think this is why the Moon formed, so at some point you fast-forward a little bit from this, Earth would have formed,
Theia has collided, and it is also molten now because huge energies, and it splashes some of it into orbit. If we fast-forward a little bit, this stuff that got splashed into orbit, it's going in that direction, that becomes our Moon, and then the rest of this material eventually kind of condenses back into a spherical shape and is what we now call our Earth. So that's how we actually think right now that the Moon actually formed.
"Ga" means "billions of years ago"
'G' for "Giga-"
"Ma" means "millions of years ago" 'M' for "Mega-" So where we are right now, the Moon has formed, and we're in what we call the Hadean period or actually I shouldn't say "period."
"Period" is actually another time period, so let me make this very clear. It's the Hadean, we are in the Hadean eon, and an eon is kind of the largest period of time that we talk about, especially relative to Earth, and it's roughly 500 million to a billion years is an eon, and what makes the Hadean eon distinctive, well, from a geological point of view what makes it distinctive is really we don't have any rocks from the
Hadean period.
We don't have any kind of macroscopic-scale rocks from the Hadean period, and that's because at that time, we believe, the Earth was just this molten ball of kind of magma and lava, and it was molten because it was a product of all of these accretion events and all of these collisions and all this kinetic energy turning into heat.
If you were to look at the surface of the Earth, if you were to be on the surface of the Earth during the Hadean eon, which you probably wouldn't want to be because you might get hit by a falling meteorite or probably burned by some magma, whatever, it would look like this, and you wouldn't be able to breathe anyway; this is what the surface of the Earth would look like. It would look like a big magma pool, and that's why we don't have any rocks from there because the rocks were just constantly being recycled, being dissolved and churned inside of this giant molten ball, and frankly the Earth still is a giant molten ball, it's just we live on the super-thin, cooled crust of that molten ball. If you go right below that crust, and we'll talk a little bit more about that in future videos, you will get magma, and if you go dig deeper, you'll have liquid iron.
What I want to do in this video is talk a little bit about the kidney-- and this is a big picture of a kidney-- and to talk about how it operates at its-- I guess you could call it its smallest functional level and that's the nephron. So we're going to talk about the kidney and the nephron. And I think you might already know the kidney.
Besides just understanding these words, we're going to see that they actually play a very important role in this actual filtration or this excretion of waste and this ability to not dump too much water or excrete too much water when we're trying to filter out our blood. So I've said before, and you might have heard it already from other lectures or from other teachers, that the functional unit of the kidney is the nephron.
And the reason why it's called a functional unit-- I'll put it in quotes-- is because that's the level at which these two things are happening. The two major functions of the kidney: the waste excretion and the maintenance of the water level in our blood system. So just to get an idea of how a nephron fits in within this picture of a kidney-- I got this picture from Wikipedia.
You can't really say, my nephrons are microscopic. They kind of have a-- at least their length when they dip down, you can say, I can see that distance. You can still jam a lot of them inside of one kidney.
And then it leaves via the efferent arterial.
Afferent towards, efferent away from the center. And I'll talk about it more in the future, but it's interesting that we're still dealing with an artery at this point. It's still oxygenated blood.
It's surrounded like that by this structure, and these are cells here so you can imagine these are all cells over here. And, of course, the actual capillaries have cells that line them so there are cells here.
It's a sphere with an opening in here that the capillary can kind of wind around in, and the space right here, this is the Bowman's space. It's the space inside the Bowman's capsule, and the whole thing has cells. All these structures are obviously made-- or maybe not so obviously-- they're made up of cells.
Filtrate is just the stuff that gets squeezed out. We can't call it urine just yet because there's a lot of steps that have to occur for it to earn the name urine. So it's only filtrate right now, and essentially what get squeezed out, I said it's about a fifth of the fluid, and things that are easily dissolved in fluid, so small ions, sodium, maybe some small molecules like glucose, maybe some amino acids.
The filtrate that just comes out at this point, sometimes it's called the glomerular filtrate because it's been filtered by the glomerulus, but it's also been filtered by those podocyte cells on the inside of the Bowman's capsule.
Let me draw something like this. And obviously, this is not exactly what it looks like, but it gives you the sense. This right here, this is the proximal tubule.
That's because it's all convoluted. The way I've drawn it is all curvy. And I just drew it curvy in two dimensions.
One point is to make the renal medulla salty, and it does this by actively pumping out salts. So it actively pumps out salts, and it does that in the ascending part of the loop of Henle. So it actively pumps out salts: sodium, potassium, chloride, or chlorine, I should say.
The descending part of the loop of Henle is only permeable to water.
So what's going to happen? If this is all salty because the ascending part is actively pumping out salt, what's going to happen to water as it goes down the descending loop? Well, it's hypertonic out here.
The distal convoluted tubule actually goes pretty close to the Bowman's capsule. And once again, I've made it all convoluted in two dimensions, but it's actually convoluted in three. And it's not that long, but I just had to get over here and
Distal is further away. It's convoluted and it's a tubule. So this right here is the distal convoluted tubule, and here we have more reabsorption: calcium, more sodium reabsorption.
Now, I don't know about you, but I think this manual bug hunting is a little bit tedious, so why don't we introduce you to some tools that will make our lives a little bit easier. All the major browsers have developer tools built into them that can help you with just the kind of problems that we are looking at, and then some.
Let's say you're some type of a hunter gatherer, and you're trying to figure out how much of your time you should spend hunting and how much of your time to spend gathering. So let's think about the different scenarios here and the tradeoffs that they involve. And just for simplicity we're going to assume that when you're talking about hunting, the only animal around you to hunt for are these little rabbits.
"Oh, and, you know, ceteris paribus, we assume this variable changes," or whatever else, they're saying we're assuming everything else is being held equal. So, ceteris means "all other things." You're probably familiar with "et cetera".
That is scenario E. And then finally, scenario F, you are spending all of your time looking for berries, you have no time for rabbits, So all of your time for berries, no time for rabbits. Zero rabbits, 300 berries.
These are all points on you as a hunter-gatherer, on your production possibilities frontier. Because if we draw a line - I just arbitrarily picked these scenarios, although I guess you could on average, get 4.5 rabbits on average, or, on average, get 3.5 rabbits, and then have a different number of berries -
I'll draw them as a dotted line. It's easier for me to draw a dotted curve than a straight curve. So this right over here, this curve right over here, represents all the possible possibilities of combinations of rabbits and berries.
Maybe somehow I'm not using my resources optimally to do this type of thing when I'm over here. Or maybe I'm just not being optimally focused, or whatever it might be. If you're talking about a factory setting, when you're talking about deciding to make one thing or another, then maybe you just aren't using the resources in an optimal way.
The answers are get, keep, and grow--are the three parts of customer relationships. As we'll see, customer relationships start with get. Get is how you actually acquire customers and get them to purchase your product.
(Applause) My name is Aisha Chaudhary and I'm 15 years old. I was born with an immune deficiency, with a life expectancy of only one year.
Today I'm going to show you how to make a mini indoor bow and arrow. Start by taking a lolly pop stick, putting it in a bowl of water And leaving it to soak for half an hour.
One of the things I just want to reemphasize because we mentioned it earlier is the difference between single-sided markets and multi-sided markets. Now, in single-sided markets the customer is the user and the payer. That's a single-sided market.
[APPLAUSE]
Good morning. It's very good to see everybody today. I'm really excited to talk to you a little bit about Search, and talk to you a little bit about Google, the evolution of
For example, the phone that I carry with me every single day is Galaxy Nexus. It's a fantastic phone. I actually have two Samsung phones in my pocket right now.
So now we've gone through the basics of javascript syntax: structuring and interacting with JSON data, and requesting data from a server.
Now, we need to talk about how to interface to the browser. More specifically, we need to talk about the DOM, or document object model. The DOM is an interface to the structure of an HTML.document, for example, the head or body element.
That way, if we submit multiple times, we don't simply create a new p tag every single time. Finally, we grab a reference to the body tag, since the body element has an ID of body we can do that, and we append "notify" to the body.
Now if we look at this in our browser, we can see we have an input form with a submit button and you can see our basic HTML down here. However, if we submit an incorrect password -- press submit -- we can see that this pops up right here, which is the text that we set our p tag to. You can also see that this p tag was created down here.
What's up everybody, I'm Alex - and I'm Mark.
We're two brothers from California teaming up to win the Biggest Baddest Bucket List.
But first, we have three minutes to show you 24 hours in Europe's coolest city - San
Sebastian.
San Sebastian has one of the best urban beaches in Europe - plus it's halfway between Mundaka and Hossegor, two of the best waves in the world.
So grab your board and paddle out.
But you can't spend all day at sea level.
Next, get some perspective by climbing the mountain in the middle of the city - Monte
Urgull.
From up here you get a view into the city's past - from the port to the fort and of course, the beautiful Playa de la Concha.
San Sebastian's perfect crescent-shaped beach made it famous when the Queen of Spain decided to build her summer place here, transforming a fishing village into a royal resort.
And it's not hard to see why.
Now it's 2016 Cultural Capital of Europe thanks to it's international Film Festival, unique
Celebrations like San Sebastian Day, and all of the awesome sculptures that turn this place into one giant open-air museum.
Put simply, San Sebastian has turned living into an art.
That's because here, art is edible.
It's called a pintxo - a tapa taken to the next level.
The old is packed with pintxos bars full of crazy culinary creations that will blow your mind for 2 euros a pop.
So let's go get one.
Nature is never far away and you can be on the Camino de Santiago in under five minutes.
On your way down, catch your breath and the sunset before getting ready for a night on the town.
Start with dinner in a traditional Basque cider house: a five course feast with all the cider you can drink.
The magic word?
Finish up your night in the old town where every other door is a bar.
Or, if you're up for it, hit up a night club on the beach where you can party 'til dawn.
And that is 24 epic hours in San Sebastian.
That was one day in one city, but we've got plans for six months on six continents.
But with so much to do and so little time, it's easy to overlook the the most important element of travel - the people who make up the cultures we visit.
So while our bucket list will cover all the essential experiences, our blogs will focus on the people we meet along the way - maybe even you.
So check out our webpage to see what we've done and imagine what we could do with the help of MyDestination.com.
We appreciate your time and your vote.
Looking at the Amazon website for books, which of the following are part of Amazon's products, and tick all that apply
Here is the code for up heapify, right now it is blank. Now suppose that we insert a new element.
Now, Javascript at first glance really doesn't resemble the same sort of object oriented programming languages that you see in C and C++ code. Now these are typically the languages that games are written in, NES, Super NES,
XBox 360, PS3, all had some resemblance of this. Now Javascript provides a way that you can define a set of variables as well as functions encapsulated as an object called a prototype. But for game dev, we're really missing the inheritance factor, that is the ability to define that prototype and have another one inherent from it.
Let's just think about this. Which are the reasons that you would want to partner? Take a look at this list and choose all that apply.
Everybody's really been looking forward to the new video from Lumpy and the Lumpettes Even Lumpy! Russell's a huge fan!

This brings us to a point where we can ask one of the most fundamental questions in theoretical computer science and that is does P=NP and in particular, here's what we actually know. This is true. We know that every problem that's in P is in NP and every problem that is NP is in EXP, that is to say any problem that you can solve in polynomial time, we can certainly solve in non-deterministic polynomial time, and any problem that we can solve in a non-deterministic polynomial time, we can also solve in exponential time, but here's what we don't know.
Welcome to the presentation on limits. Let's get started with some-- well, first an explanation before I do any problems.
"€œThe Unconsidered Life" [peaceful music]
One very, very important moment in the history of philosophy is when Socrates said,
And I think one consequence of this is that people should think very critically and deeply about, for example, the claims of religion. You know, is that the source of value in the world, or is it our humanity and our connection with other human beings? So across a whole range, this central demand is to be critical, to be reflective, to think for oneself.
Bertrand Russell once famously said, "Most people would rather die than think, and most people do," and one doesn't want to be one of them.
[quote on screen]
The cofounder of the social, news, and entertainment website "Reddit" has been found dead. He certainly was a prodigy, although he never kinda thought of himself like that. He was totally unexcited about starting businesses and making money.
Governments have insatiable desire to control. He was potentially facing 35 years in prison and 1 million dollar fine. Raising questions to prosecutorial zeal, and I would say even 'misconduct,' have you looked into that particular matter and reached any conclusions?
Growing up, you know, I slowly had this process realizing that all the things around me that people had told me were just the natural way of things were, or the way things would be, weren't natural at all. There were things that could be changed. And there were things, more importantly, were WRONG and should change.
Welcome to story reading time. The name of the book is "Paddington at the Fair." He was born in Highland Park and grew up here.
Aaron came from a family of three brothers, all extraordinarily bright. "...Oh the box is tipping over..."
[Boys screaming]
So, we were all, you know, not the best behaved children. You know, three boys, running around all the time, causing trouble...
"Hey, no, no, no!"
- Aaron! - What? But I've come to the realization Aaron learned how to learn at a very young age.
"One, two, three, four, five, six, seven, eight, nine, ten!"
- Knock, knock! - Who's there? - Aaron.
"Here's a little picture of what the planets are. Each planet has a symbol. Mercury symbol, Venus's symbol, Earth symbol, Mars symbol, Jupiter symbol..."
"Free family entertainment in downtown Highland Park" She was floored, and astonished that he could read. It's called "My Family Seder."
"Z, Y, X, W, V, U, T..." I remember, he came home from his first Algebra class and he was like, "Noah, let me teach you Algebra!" and I'm like, "What IS Algebra?" He was always like that.
We all had computers, but Aaron really took to them, really took to the Internet. - Working at the computer? - Nah...
"How come... Mommy, why is nothing working?" He started programming from a really young age.
Aaron made an ATM using Macintosh and a cardboard box. One year for Halloween, I didn't know what I wanted to be. And he thought it would be really really cool if I dressed up like his new favorite computer, which at that time, the original iMac.
"Host Aaron, stop, guys, come on, look at the camera!" "Spiderman looks at the Camera." He made this website called "The Info," where people can just fill in information.
"This is a terrible idea. You can't just let anyone author the encyclopedia.
The whole reason we have scholars is to write these books for us.
How could you ever have such a terrible idea?"
Me and my other brother were like, "Aw, you know, Wikipedia is cool, but... we had that in our house like, 5 years ago." Aaron's website, theinfo.org, wins a school competition hosted by the Cambridge-based web design firm ArsDigita.
We all went to Cambridge when he won the ArsDigita prize and we had no clue what Aaron was doing. It was obvious that the prize was really important. Aaron soon became involved with online programming communities, then in the process of shaping a new tool for the Web.
"You need to hear about it!" "Yeah, what is it?" "It's this thing called RSS."
And he explains to me what RSS is. I'm like, "Why is that useful, Aaron?" "Is any site using it?
"You know, when are you gonna come out to one of these face-to-face meetings?" And he said, "You know, I don't think my mom would let me. I've just turned fourteen."
"Christ, we really want to meet him. That's extraordinary!" He was part of the committee that drafted RSS.
So his mom started bundling him on planes in Chicago. We'd pick him up in San Francicso. We'd introduce him to interesting people to argue with, and we'd marvel at his horrific eating habits.
He takes on this, like an alpha nerd personality, where he's sort of like, "I'm smarter than you, and because I'm smarter than you, I'm better than you, and I can tell you what to do." It's an extension of, like, him being kind of like a twerp. So you aggregate all these computers together and now they're solving big problems
I first met him on IRC, on Internet Relay Chat. He didn't just write code, he also got people excited about solving problems he got. He was a connector.
I don't know. It's very exciting to see the Supreme Court, especially in such a prestigious case as this one.
Lessig was also moving forward with a new way to define copyright on the Internet. It was called Creative Commons.
So the simple idea of Creative Commons is to give people--creators-- a simple way to mark their creativity with the freedoms they intended to carry. So if copyright is all about "All Rights Reserved", then this is a kind of a "Some Rights Reserved" model. I want a simple way to say to you, "Here's what you can do with my work, even if there are other things which you need to get my permission before you could do."
In 2004, Swartz leaves Highland Park and enrolls in Stanford University. He'd had ulcerative colitis which was very troubling, and we were concerned about him taking his medication. He got hospitalized and he would take this cocktail of pills every day, and one of those pills was a steroid which stunted his growth, and made him feel different from any of the other students.
Swartz was offered a spot at a new start-up incubation firm called Y Combinator, lead by Paul Graham. He's like, "Hey, I have this idea for a website." And Paul Graham likes him enough, and says, "Yeah, sure."
- And he's how old at the time?
- 19, 20. So it was in this apartment. They sat around on what predated these couches, hacking on Reddit, and when they sold Reddit they threw a giant party, and then all flew out to California the next day, and left the keys with me.
It was funny, you know, he'd just sold his start-up so we all presumed he was the richest person around but he said, "Oh no, I'll take this tiny little shoebox-sized room. That's all I need." It was barely larger than a closet.
After he started working in San Francisco at Condé Nast, he comes into the office and they want to give him a computer with all this crap installed on it and say he can't install any new things on this computer, which to developers is outrageous. From the first day, he was complaining about all the stuff. "Gray walls, gray desks, gray noise.
Swartz was inspired by one of the visionaries he had met as a child. The man who had invented the World Wide Web, Tim Berners-Lee. In the 1990s, Berners-Lee was arguably sitting on one of the most lucrative inventions of the 20th century, but instead of profiting from the invention of the World Wide Web, he gave it away for free.
I feel very strongly that it's not enough to just live in the world as it is, to just kind of take what you're given, and you know, follow the things that adults told you to do, and that your parents told you to do, and that society tells you to do. I think you should always be questioning. I take this very scientific attitude, that everything you've learned is just provisional, that it's always open to recantation or refutation or questioning, and I think the same applies to society.
We just started spending a lot of time, just kind of as friends. We would just talk, for hours, into the night. I definitely should have understood that he was flirting with me.
We were extremely close from the beginning of our romantic relationship. We just...we were in constant contact. But we're both really difficult people to deal with.
- What are you doing?
(Quinn) - Flicker has video now. Swartz threw his energy into a string of new projects involving access to public information, including an accountability website called Watchdog.net, and a project called The Open Library.
So, the Open Library Project is a website you can visit at openlibrary.org, and the idea is to be a huge wiki, an editable website with one page per book. So for every book ever published, we want to have a web page about it that combines all the information from publishers, from booksellers, from libraries, from readers onto one site, and then gives you links where you can buy it, you can borrow it, or you can browse it. I love libraries.
As the founder of Public.Resource.Org, Malamud wanted to protest the PACER charges. He started a program called The PACER Recycling Project, where people could upload PACER documents they had already paid for to a free database so others could use them. The PACER people were getting a lot of flack from Congress and others about public access, and so they put together a system in 17 libraries across the country that was free PACER access.
"Gee, we'd like to join the Thumb Drive Corps." Around that time, I ran into Aaron at a conference. This is something that really has to be a collaboration between a lot of different people.
"Hey, I am thinking about an intervention on the PACER problem." Shultze had already developed a program that could automatically download PACER documents from the trial libraries. Swartz wanted to take a look.
An FBI agent drives down our home's driveway, trying to see if Aaron is in his room. I remember being home that day, and wondering why this car was driving down our driveway, and just driving back up. That's weird!
JSTOR and Thomson Isi to get access to scholarly journals that the rest of the world can't read. These scholarly journals and articles are essentially the entire wealth of human knowledge online, and many have been paid for with taxpayer money or with government grants, but to read them, you often have to pay again handing over steep fees to publishers like Reed-Elsevier. These licenses fees are so substantial that people who are studying in India, instead of studying in United States, don't have this kind of access.
"How much would it cost to open up JSTOR in perpetuity?" And they gave some--I think it was two hundred million dollars, something that Aaron thought was totally ridiculous. Working on a fellowship at Harvard, he knew users on MlT's famously open and fast network next door had authorized access to the riches of JSTOR.
Swartz saw an opportunity. You have a key to those gates, and with a little bit of shell script magic, you can get those journal articles.
On September 24, 2010, Swartz registered a newly purchased Acer laptop on the MlT network, under the name "Garry Host". The client name was registered as "GHost laptop".
The JSTOR database was organized, so it was completely trivial to figure out how you could download all the articles in JSTOR, because it was basically numbered. It was basically slash slash slash...number article 444024 and -25 and -26. He wrote a Python script called keepgrabbing.py, which was like, keeping grabbing one article after another.
Aaron, ultimately, obviously is the cat because he has more technical capability than the JSTOR database people do in defending them. Eventually, there was an unlocked supply closet in the basement of one of the buildings, and he went, instead of going through WiFi, he went down there and he just plugged his computer directly into the network and just left it there with an external hard drive downloading these articles to the computer. Unknown to Swartz, his laptop and hard drive had been found by authorities.
"Dude, what are you doing, you know, cut it out. Who are you?" They could have done all that kind of stuff, but they didn't.
At first, the only person caught on the glitchy surveillance camera was using the closet as a place to store bottles and cans.
But days later, it caught Swartz.
Swartz is replacing the hard drive. He takes it out of his backpack, leans out of frame for about five minutes, and then leaves.
And then they organized, like, a stakeout where, as he was biking home from MlT, these cops came out from either side of the road, or something like that, and started going after him. He describes that he was pressed down and assaulted by the police. He tells me that they--it's unclear that they were police that were after him.
President Bush used The Patriot Act to establish a network of what they called "Electronic Crimes Task Forces". The bill before me takes account of the new realities and dangers posed by modern terrorists. According to the Secret Service, they are primarily engaged in activity with economic impact, organized criminal groups, or use of schemes involving new technology.
"Head of the Computer Crimes Division or Task Force" I don't know what else he had going, but you're certainly not much of a "Computer Crimes Prosecutor" without a computer crime to prosecute, so he jumped on it, kept if for himself, didn't assign it to someone else within the office or the unit and that's Steve Heymann. Prosecutor Stephen Heymann has been largely out of public view since the arrest of Aaron Swartz, but he can be seen here, in an episode of the television show "American Greed", filmed around the time of Aaron's arrest.
But when Aaron writes a script that says download download download, a hundred times in a second, there's no obvious damage to anybody. If he does that for the purpose of gathering an archive to do academic research on it, there is never any damage to anybody. He wasn't stealing.
He wouldn't give off any sensitive information about his whereabouts during this time, because he was so afraid that the FBI would be waiting for him. It was a time of unprecedented social and political activism. Time Magazine would later name, as their 2011 Person of the Year, "The Protester".
Anonymous, which is a kind of protest ensemble that has a lot of hackers in its ranks, were going on various sprees of sorts. If you compare that to what he did, this stuff should have been left behind for MlT and JSTOR to deal with, in a kind of private, professional matter. It should have never gotten the attention of the criminal system.
Before he was indicted, Swartz was offered a plea deal that involved three months in prison, time in an halfway house, and a year of home detention, all without the use of a computer. It was on the condition that Swartz plead guilty to a felony. Here we are: we have no discovery, no evidence whatsoever about what the government's case is, and we have to make this immense decision where the lawyer is pushing you to do this, the government is giving you a non-negotiable demand, and you're told that your likelihood of prevailing is small, so whether you're guilty or not, you're better off taking the deal.
And you know he really--he really wanted that to be his life. He hadn't killed anybody. He hadn't hurt anybody.
Swartz turned down the plea deal. Heymann redoubled his efforts. Heymann continued to press us at all levels.
Right, a proffer letter. -In which you basically handed information to them in exchange for protection from prosecution.
-So, it wasn't handing information over. It was--at least that's not how I saw it-- it was just having a discussion, having an interview with them.
-Well, they're asking you questions...
-They're asking me questions. -and they can ask about whatever they want...
-Right. - and whatever they learn...
-I really...
-They can't have you prosecuted. -Right, and I repeatedly tried to go in naked. I repeatedly--I repeatedly tried to turn down the proffer letter.
"Information is power. But like all power, there are those who want to keep it for themselves."
"The world's entire scientific and cultural heritage, published over centuries in books and journals, is increasingly being digitized and locked up by a handful of private corporations."
"Meanwhile, those who have been locked out are not standing idly by."
"You have been sneaking through holes and climbing over fences, liberating the information locked up by the publishers and sharing them with your friends."
"But all of this action goes on in the dark, hidden underground."
"It's called stealing or piracy, as if sharing a wealth of knowledge were the moral equivalent of plundering a ship and murdering its crew."
"But sharing isn't immoral — it's a moral imperative."
"Only those blinded by greed would refuse to let a friend make a copy."
"There's no justice in following unjust laws."
"It's time to come into the light and, in a grand tradition of civil disobedience, declare our opposition to this private theft of public culture." The Manifesto itself was allegedly written by four different people, and also edited by Norton. But it was Swartz who had signed his name to it.
The things that I'd done shouldn't have added up that way. I hadn't done anything wrong, and everything had gone wrong, but I was never...
I'm still angry. I'm still angry that you could try your best with these people to do the right thing, and they'd turn everything against you. And they will hurt you with anything they can.
-You know, four people in this city should cause a massive global public outcry.
-You know, we need a petition signer. Without telling her specifics, he warned her he was involved in something he called simply "The Bad Thing". And I had sort of crazy theories, like, that he was having an affair with Elizabeth Warren or something.
"It was the government's decision whether to prosecute, not JSTOR's." And so it's our belief that, with that, the case will be over. That we should be able to get Steve Heymann to drop the case, or settle it in some rational way.
Well, because I think they wanted to make an example out of Aaron, and they said they wanted--the reason, why they wouldn't move on requiring a felony conviction and jail time, was that they wanted to use this case as a case for deterrence. They told us that. [Interviewer]
-This was going to be an example? -Yes.
-He was going to be made an example? - Yes. Steve Heymann said that.
Prosecutor Stephen Heymann later reportedly told MlT's outside counsel that the straw that broke the camel's back was a press release sent out by an organization Swartz founded called "Demand Progress".
According to the MlT account, Heymann reacted to the short statement of support, calling it a "wild internet campaign" and a "foolish move" that moved the case from a human one-on-one level to an institutional level. That was a poisonous combination: a prosecutor who didn't want to lose face, who had a political career in the offing, maybe, and didn't want to have this come back and haunt them. You spend how many tax dollars arresting someone for taking too many books out of the library, and then got your ass handed to you in court?
MlT doesn't defend Aaron which, to people inside of the MlT community, seems outrageous, because MlT is a place that encourages hacking in the biggest sense of the word. At MlT, the idea of going and running around on roofs and tunnels that you weren't allowed to be in was not only a rite of passage, it was part of the MlT tour, and lockpicking was a winter course at MlT. They had the moral authority to stop it in its tracks.
"We don't want you to do this. You're overreacting. This is too strong." ...that I'm aware of.
"It's not?" "No," he said, "it's a bill about the freedom to connect." Now I was listening.
Demand Progress is an online activism organization, we've got around a million and a half members now, but started in the fall of 2010. Aaron was one of the most prominent people in a community of people who helped lead organizing around social justice issues at the federal level in this country. SOPA was the bill that was intended to curtail online piracy of music and movies, but what it did was basically take a sledgehammer to a problem that needed a scalpel.
Really?
[laughter]
"Nerds"?
[laughter]
You know, I think, actually the word you're looking for is "experts"... [laughter]
to enlighten you so your laws don't backfire [audience laughter and applause] and break the internet. We use the term "geek" but we're allowed to use that because we are geeks. The fact that it got as far as it did, without them talking to any technical experts, reflects the fact that there is a problem in this town.
"I think we might win this." And I was like, "That would be amazing." Calls to Congress continue.
So, yeah, maybe sometimes you feel like you're not being listened to, but I'm here to tell you that you are. You are being listened to. You are making a difference.
Stop PlPA. Stop SOPA. [Crowd cheers]
Some of the biggest internet companies, to put it frankly, would benefit from a world in which their little competitors could get censored. We can't let that happen. For him, it was more important to be sure that you made a small change than to play a small part in a big change.
"I think about it in this really scientific way of measuring my impact, and this shows that it's possible."
"The thing that I want to do with my life is possible."
"I have proved that I can do it, that I, Aaron Swartz, can change the world." For a guy who never really thought he had done much--which was Aaron-- was one of the few moments where you could really see that he felt like he had done something good, feeling like here is his maybe one and only victory lap. Everyone said there was no way we could stop SOPA.
"Okay, we need to galvanize opposition today because today is when it matters..." The prosecution, in my estimation of Aaron Swartz, was about sending a particular, laserlike message to a group of people that the Obama administration sees as politically threatening, and that is, essentially, the hacker, the information, and the democracy activist community, and the message that the Obama administration wanted to send to that particular community was, in my estimation, "We know you have the ability to make trouble for the establishment, and so we are going to try to make an example out of Aaron Swartz to scare as many of you as possible into not making that trouble." And the government said, "Oh, the legal opinions we're using to legalize the spying program are also classified, so we can't even tell you which laws we're using to spy on you."
[Interviewer] And so just to follow--personally, how do you feel the fight is going? It's up to you!
On September 12, 2012, federal prosecutors filed a superseding indictment against Swartz, adding additional counts of wire fraud, unauthorized access to a computer, and computer fraud. Now, instead of four felony counts, Swartz was facing thirteen. The prosecution's leverage had dramatically increased, as did Swartz's potential jail time and fines.
You can have something like eHarmony or Match.com, and somebody sort of inflates their own personal characteristics, and all of a sudden, depending on the jurisdiction and the prosecutors, they could be in a whole host of troubles. We all know what "Terms of Use" are. Most people don't read them, but not abiding by their terms could mean you are committing a felony.
Swartz's isolation from friends and family increased. He had basically stopped working on anything else, and the case was, in fact, taking over sort of his whole life. One of Aaron's lawyers apparently told the prosecutors that he was emotionally vulnerable, and that that was something they really needed to keep in mind so that they knew that.
-Was in millions? - Yes. I think he didn't want to be a burden to people.
I don't think they would have convicted Aaron. I think we would have walked him out of that courthouse, and I would have given him a big hug, and we would have walked across that little river in Boston, and gone and had a couple of beers. I really thought that we were right.
I just thought, we've lost one of the most creative minds of our generation. I was like, the whole world fell apart at that moment.
It was one of the hardest nights of my life. I just kept screaming, "I can't hear you! What did you say?
Yeah, none of it made any sense, and really still doesn't. I was so frustrated, angry.
[exhales]
You know, I tried to explain it to my kids. My three-year-old told me that the doctors would fix him.
I've known lots of people that have died, but I've never lost anybody like this, because everybody feels, and I do too, there is so much we could have--more to do like... I just didn't know he was there. I didn't know this was what he was suffering and...
And I just wanted it to not be real, and then...
and then I just looked at his Wikipedia page and I saw the end date:
"to 2013".
[quote on screen]
My first thought was: what if nobody even notices? You know, because it wasn't clear to me how salient he was. I had never seen anything quite like the outpouring I saw.
He was the internet's own boy, and the old world killed him. We are standing in the middle of a time when great injustice is not touched. Architects of the financial meltdown have dinner with the president, regularly.
He was, in my humble opinion, one of the true extraordinary revolutionaries that this country has produced. I don't know whether Aaron was defeated or victorious, but we are certainly shaped by the hand of the things that he wrestled with. When we turn armed agents of the law on citizens trying to increase access to knowledge, we've broken the rule of law--we've desecrated the temple of justice.
Change does not roll in on the wheels of inevitability, it comes through continuous struggle. Aaron really could do magic, and I'm dedicated to making sure that his magic doesn't end with his death. He believed that he could change the world, and he was right.
Since Swartz's death, Representative Zoe Lofgren and Senator Ron Wyden have introduced legislation that would reform the Computer Fraud and Abuse Act-- the outdated law that formed the majority of the charges against Swartz. It's called "Aaron's Law". Aaron believed that you literally ought to be asking yourself all of the time:
I wish we could change the past, but we cannot. But we can change the future and we must. We must do so for Aaron, we must do so for ourselves.
Sorry... and he said the reason he was on the news was 'cause they'd done it. They were shipping an early test for pancreatic cancer that was going to save lives, and he said, "This is why what Aaron did was so important." Because you never know, right?
[Aaron's dad] Very good, Aaron. Very good.

So let's follow our Jersey Square team down and see what they've done for customer relationships. We'll it's really interesting to remember when they first started. Customer relationships for then said search ads, social medium and stadium promotions.
So, that's all I'd like to say about Path Links for now. Next I want to focus for a little while on the notion of a clustering coefficient. Now, you might be less familiar with this notion of clustering coefficient than you are with paths and graphs, so
So say, V is that node and Kv is its degree and Nv of V is the number of links between the neighbors of V. So, let's look at this example graph to ground out some of these concepts. So here we've got graph, let's call this node V. Could point to any of them but I'm going to go with this one.
Let's take a look at the neighbors of V. Those are the nodes that are directly connected to V in the graph. We've got this one, and this one, and this one, and this one. So the number of those neighbors is exactly the degree of V, which in this case is 4.
And now let's look at the links between these neighbors of V. So, there is this one that goes between the two pink nodes and that seems to be it. This node isn't connected to any other pink node. This is not connected to any pink node and so on.
We take twice the number of neighbor links divided by the degree of V times one minus the degree of V. Now, this may look a little odd but let's compute what it is and then I'll explain it.
So in this case, two times Nv just one, divided by K times K minus one. So it's four times three. And the result we get in this case for this particular V is 1/6.
So what this represents is actually the fraction of possible interconnections between the neighbors of V. So, because it's a fraction, we're expecting it to be something between zero and one. And in fact we can get zero if we've got something that's like a star. So V has edges going out but none of those connect to each other.
For the work that it's doing is it's going to do a series of swaps possibly making it all the way to the bottom of the tree but never further than that. And the comparison, it does a constant number of comparisons at each level. It does a constant amount of work to do the swap and it doesn't have to touch anything else on the tree other than the longest path and the length of this path is the depth of the tree which is the log n.
There's only one that's true here, and that's that the song seems to have had an effect on engagement, but not learning. Think of it this way. Let's assume that the song had no effect.
Sarah has $48. She wants to save 1/3 of her money for a trip. How many dollars should she set aside?
Use 48 as the denominator and find an equivalent fraction to 1/3. So what they want us to do in this problem is they want us to say, OK, we want 1/3 of her money, but we want to write this as an equivalent fraction where we have 48 in the denominator. So this is equal to something, some blank up here.
And 1/3 is one of those three pieces.
That is what 1/3 means. Now, if we want express this as a fraction over 48, how can we do that? Well, we're going to have to split this thing into 48 pieces.
Well, 3 times 16 is 48, so if we split each of these into 16 pieces-- and it's going to be hard to draw here, but you can imagine. Let's see, you split it into two, now we've split it into four, now you split it into eight. You're just going to end up with a bunch of lines here, but you can imagine, you can just split each of these.
Well, that represents 16 of the 48. It represents these 16 right here. It represents these 16 right there, so 1 over 3 is the exact same thing.
3 times 16 is 48. And that's literally the process of going from 3 pieces to 48 pieces. We have to multiply by 16.
So 1/3 of 48 is 16, or 16/48 is 1/3. Hopefully, that make sense to you.
So what defines a partner? What's really interesting is that this has to be a 2-way street. One way we say that is shared economics.
We learned in the imaginary numbers video, that hopefully you've watched, that every now and then in certain equations you end up with a square root of a negative number. You know, you end up with square root of negative one or square root of negative nine. And since any real number, when you square it, is either zero or positive, this was undefined for us.
Let me see. You could make the vertical axis. The vertical axis you could call it the imaginary axis.
This is a symbol for the set of real numbers. And five plus twoi, well it's real part is five. So one, two, three, four, five.
So you get b times d, which is bd. And then what's i times i? It's i squared, or negative one.
It's d squared times negative one, so it becomes c squared-- oh, I'm out of time. Actually, let me continue the division in the next video, because it can get involved. See you soon.
OK, hopefully, my tool is working now. But anyway, so we were saying when x is equal to minus 0.001, so we're getting closer and closer to 0 from the negative side, f of x is equal to minus 1,000, right? You can just evaluate it yourself, right?
All right, so to do the last little bit of this proof to show that 3-colorability is NP hard, we're going to show that if we had the ability to solve 3-colorability problems in polynomial time, then we could solve three SAT problems in polynomial time as well, and so what we need to be able to do to show that is if you walk up to me with any 3-CNF formula, I can quickly turn it into a 3-colorability problem, which is going to be a graph such that that graph is 3 colorable if and only if the original formula the 3-CNF formula that were given is satisfiable. So CNF here just means conjunctive normal form.
Let's multiply 9 times...8,000...8,085. That should be a pretty fun little calculation to do. So like always let's just rewrite this, so I'm going to write the 8,085.
So the consequences of understanding a new market are essential for a startup. This was a startup killer for decades. In a new market, there are no customers, so revenues might extend out for years.
Use less than, greater than or equal to compare the two fractions 21/28 and 6/9. Now, your impulse might just be to look at these numbers and say, oh, look, these are larger numbers than those. This must be bigger.
So 21/28, we want to put this in simplified form.
21 is the same thing as 3 times 7.
28 is the same thing as 4 times 7. They're both divisible by 7. Now, if you divide the numerator and the denominator by 7, 3 times 7 divided by 7 is just going to be 3.
4 times 7 divided by 7 is just going to be 4. So this guy right here is 3/4, is equivalent to 3/4. Now, let's think about what 6/9 is.
6/9 literally means one, two, three, four, five six.
6/9 references 6 of the 9 potential pieces, 6 of these one-ninth of a candy bar piece, however you want to think about it. Now, 6 is the same thing as 2 times 3, so you can view it as two groups of 3. Let me do it this way.
9 is equivalent to 3 times 3, or three groups of 3. So 9 is equivalent to that's one group of 3, that is two groups of 3, and now this is three groups of 3. So we could redraw this as-- so if we just draw just the groups of 3, it would look like this.
9 is 3 times 3. If you divide 2 times 3 by 3, you get 2. If you divide 3 times 3 by 3, you get the 3.
2/3, which is the same thing as 6/9, or 3/4? I didn't do 21/28 because it would've taken forever to draw. So what does 3/4 look like?
What is 3/4? So if we were to take this exact same square-- so let me redraw it.
3 in the denominator here-- so let me make it very clear. This represents 2/3. Now, this is going to represent, we have four pieces, and if we're coloring in three of them, so if we're talking about 3/4, that's one-- let me draw it like this, actually.
2/3 gets us to this far of the candy bar, while 3/4 is a little bit more of the candy bar. 2/3 is about that far, 3/4 is even more, so 3/4 is larger than 2/3.
This is a photograph by the artist Michael Najjar, and it's real, in the sense that he went there to Argentina to take the photo. But it's also a fiction. There's a lot of work that went into it after that.
But I think the point is that this is metaphor with teeth, and it's with those teeth that I want to propose today that we rethink a little bit about the role of contemporary math -- not just financial math, but math in general. That its transition from being something that we extract and derive from the world to something that actually starts to shape it -- the world around us and the world inside us. And it's specifically algorithms, which are basically the math that computers use to decide stuff.
(Laughter) And as with Amazon, so it is with Netflix. And so Netflix has gone through several different algorithms over the years.
(Laughter) Like the things that people use. All it has is just the number that moves up or down and that red button that says, "Stop."
(Laughter) And it's not the money that's so interesting actually. It's what the money motivates, that we're actually terraforming the Earth itself with this kind of algorithmic efficiency.
(Applause)
Everything that has a beginning must have an end
Simplify 48/64 to lowest terms. Let's see if we can visualize this. So we have 64.
The 48 is this purple area right over here. So let me write it over here.
48/64, and we want to write it in lowest terms, and we'll talk more about what lowest terms even means. Now, is there a way to group these 48 or these 64 into groups of numbers that will maybe simplify them a little bit? And to think about that, you'd have to think about what is the largest factor that is common to both 48 and 64?
And 16/16 is 1, and you're just left with 3/4. Now, if you didn't immediately recognize that 16 goes into both 48 and 64, you could do it step by step. So let's say we started off with 48/64.
Divide by 4, you get 8.
So 48/64 is the same thing as 24/32, which is the same thing as 6/8. And these are both divisible by 2, so if you divide the numerator by 2, you get 3. You divide that the denominator by 2, you get 4.
Meet Tony. He's my student. He's about my age, and he's in San Quentin State Prison.

"Let's do this." Thank you. (Applause)
The New South Wales government has unveiled a radical solution to the water crisis.
It plans to tap into an abandoned reservoir under the city. $95 million will be spent on a state-of-the-art water recycling facility in the heart of Sydney. My name is Natasha Warner and I've worked in news and current affairs for well over 10 years. I knew that I wanted to tell stories.
"Oh, yeah, there was something going on there." I came across a YouTube video which showed some youths defacing and vandalising areas around the tunnels.
Sef? Did you do this? You are fucking kidding me!
Sef, come on, let's get out of here. Just fucking give me the torch, you bitch! No, don't!
Sef!
Sef?
Sef? What the hell, Sef? Come on!
Hold on. Sef, ANSWER ME!
Sef! Fuck this. I'm out of here.
Dez, hold on. Don't go anywhere. Wait.
J, come on! Dez, stop!
Dez, don't rack off! What the fuck are you doing? Help!
Sef?
Sef, answer me, please! Once I saw that clip, I thought, "This is a story I can go to John with." You know, "Finally it's got some strength."
Trev? OK.
Trev, I understand you've been living it rough for quite some time now. What circumstances took you to living in the tunnels? Uh...
Trev? Hmm. Are you OK?
Tangles and I would go off and we'd just start getting stuck into it, filming like we always would. You know, don't really need direction, we'd just get into it. Once we got in sort of a little bit further, there were whole sections of tunnels that were absolutely, absolutely pitch black.
Uno, dos, tres, cuatro. Thanks, guys. The lake was just... so... vast.
Tangles, are you right? Yeah, slipped. There's your dip, mate.
Tangles, as much as we used to joke around and muck around together, when it came time to work, you know, he was very serious, and it wasn't time for joking. Creative department's ready. Just letting you know.
Righto, Nat. Basically the bell room was built as like a air raid sort of alert back in the war. They would use it to warn people of danger.
Tangles decided to, um, go into the adjoining room off the bell room and boom it from there just to basically kill the sound of the level of the bell, which was just making his levels peak out. I don't really know much about recording sound, but I did at the time remember thinking, "That's a bit weird." You know, why would you do that?
Tangles! Shit.
Tangles! Pete, we need some light down here, mate.
Tangles! Quick, light. Shit.
Tangles! What did you hear in the headphones?
Tangles! What did you hear in your headphones?
Tangles! Would he be dickin' us round?
Tangles!
Tangles, come on, mate! Steve, through here.
Tangles!
Tangles! Yo, Tangles! Here, I'll go down here.
Tangles, you good? Yep. Ready to go.
Tangles! Maybe through here... No, that's a dead end.
Tangles! Watch your step. Tangles!
Ah, great. What's up? Battery.
Tangles! Now, I had my camera light and I knew I had about two, maybe three hours tops worth of light. Steve, where's your kit?
Tangles! Steve, where's your kit? What?
Tangles! Steve, wait! C'mon, Nat.
Tangles! Yeah, I panicked. You know, it wasn't like I 'm trying to be a hero or anything.
Tangles! So, what do you think? Think of what?
I mean he can't contact us. Maybe he's waiting for us. No, Steve's right, OK?
Tangles!
Tangles! This way!
Tangles! I heard him through here.
Tangles!
Tangles! I'm coming, mate! Oh, fuck it!
Tangles!
Tangles! Get down and grab it at the bottom. Fuck it.
- Nat! Pete, are you OK? Stay with me.
I was sent some problems by one of the viewers out there. I believe his name is Cortaggio or Cortajio, I apologize. I'm sure I'm mispronouncing it.
I wanted to make sure I wasn't giving the incorrect title. So, an officer on horseback stars at the back of a column. So he starts here.
And then t2 would be time to back.
There might be other ways to solve this, but this is the way that's jumping out into my brain. So let's figure out what the time to the front of the column is. So, over some period of time -- so, how far is the column going to move over to t1?
And how far is this guy going to move? Well, we're saying over time, when he moves to the front of the column. So, this whole column is moving to the right.
Copying is not theft. Copying is not theft. Stealing a thing leaves one less left
Five years ago, I experienced a bit of what it must have been like to be Alice in Wonderland. Penn State asked me, a communications teacher, to teach a communications class for engineering students. And I was scared.
"space and time," which is so much more accessible to us? And making your ideas accessible is not the same as dumbing it down. Instead, as Einstein said, make everything as simple as possible, but no simpler.
We can do this by modifying the listcomponentsizes algorithm from the previous example. Call the algorithm check connection, and it takes a graph, but it also takes v1 and v2.It's going to do something similar to before. It's going to start off with the assumption that none of the nodes have been marked so far as reachable.
Let's see how we came up with our answer. Number 1, our pay-per-click number was 75 cents for each customer that we go to our side and we know we got 4,025 customers, and so if we multiply that out, we know we've spent $3,018. And on the next number that's important is that not all 4,025 actually activated and in fact, if we look at this number, our conversion number, only 3.7% converted.
We're asked to select which fractions add together to make 25 over 22, or 25/22. You can use as many fractions as you need. Put all unused fractions into the trash can.
It always helps me to see a lot of examples of something so I figured it wouldn't hurt to do more scientific notation examples. So I'm just going to write a bunch of numbers and then write them in scientific notation. And hopefully this'll cover almost every case you'll ever see and then at the end of this video, we'll actually do some computation with them to just make sure that we can do computation with scientific notation.
-- let me do it in a different color -- 6.4 times 10 to the minus 6 times 3.2 times 10 to the 11th. Which we saw in the last video is equivalent to 6.4 times 3.2. I'm just changing the order of our multiplication.
You multiply that side by ten and you get times ten to the -- times ten is just times ten to the first. You can just add the exponents. Times ten to the sixth.
32 is half of 64 or 3.2 is half of 6.4, so this is 0.5 right there. And what is this? This is ten to the eleventh over ten to the minus six.
Let's think about it for a little bit, you'll see there is really only two possibilities. If we're trying to find the shortest path from I to J that is allowed to use K and any of the nodes with numbers smaller than K. There are two possibilities.
When this is all over, when this loop is done, we have the D⁰n, but D⁰[n,i,j} is the length of the shortest from I to J only hopping on nodes that are numbered less than n, but that's all the nodes. All the nodes are numbered less than n. They are all numbered from 0 to n-1. so this is the length of the shortest path from I to J, unrestricted, full stop. so that's pretty cool, and if you think about what's going on here, this initialization step runs over all pairs of nodes so that's n².
Now it's worth putting out that this magical program, Texture Packer, provides a nice little output option that you can see right here, called trim. What this option will do, is that for each image, it'll find out the true boundaries for it. So let's say an artist gives you a texture but only puts pixels in the center part of it.
Now, the next market type is a new market. Customers don't exist today. As the real questions are, if they don't exist, how will they find out about you?
Faults That Have Occurred Due To Violence Or Violent Intent Today, there was a wish that we should take the subject of violence (himsa) Violence (himsa)
This is called violent intent (bhaav himsa) - [himsa] involving kashayo where one has hurt someone due to pride (maan), or hurt someone due to greed (lobh), or hurt someone due to attachment (moha), or where one has hurt someone to get their way (dharyu karvu). These are known as himsa of kashays.
So let us remember [all of this] and wash it off Sometimes it may happen that we try to save the mosquito by pushing it aside but the mosquito is sitting there with its stomach so full that simply by moving, the poor thing dies Bed bugs may get killed at night unknowingly
For all these faults [by] remembering each and every living being [may I] feel heartfelt repentance towards the Soul of all these beings [may I] wash away the faults Give me the absolute energy (shakti) to do such a samayik [I surrender] my mind- speech- body
For this question, we want you to implement mark_component using the open list as discussed in lecture. This means that mark_component should not use recursion.
There's another way to look at this types of value propositions, kind of as a Venn diagram. What comes from technical insights are making things more efficient or smaller or faster and sometimes lower cost and simpler. What comes from market insights are better distribution and bundling and branding.
Welcome to the presentation on multiplying expressions. Let's get started. So if I were to ask you what x plus two times, let me use a different color, times x plus three equals, at first you'd be like, huh, that's a little strange.
Let's do twox plus y. Whoops, some parentheses. I'll stay in one color, since I think you understand what we're doing.
Times threex plus twoy. Well, once again, this is the same thing as -- and we could just do it in a little different way, a little different order. But we could distribute it like this.
So any expression like twox plus two squared, is just that expression times itself. And now we can just do it as -- this is the same thing as twox times twox plus two. Plus two times twox plus two.
Welcome to the presentation on finding the equation of a line. Let's get started. Say I had two points.
And this problem, you could actually look at it and figure it out, but let's do it mathematically. So the equation for the slope m: it's rise over run. Another way to view that is for any amount that you run along the x-axis, how much do you rise?
The change in y is four minus two. We just took this four minus this two over three minus one. My phone was ringing.
And that's just this three minus this one. So if we just solve for it, we get four minus two is two, and three minus one is also two, so we get the slope is equal to one. And that makes sense because when we move over one in x, we go up exactly one in y.
The y-intercept is one, which is exactly here, zero comma one, and the slope is one, and that's pretty obvious. For every amount that we move to the right, we move the same amount up, so the slope is one. Let's do another problem.
I'm Dr. David Hanson, and I build robots with character. And by that, I mean that I develop robots that are characters, but also robots that will eventually come to empathize with you. So we're starting with a variety of technologies that have converged into these conversational character robots that can see faces, make eye contact with you, make a full range of facial expressions, understand speech and begin to model how you're feeling and who you are, and build a relationship with you.
We're working with the Machine Perception Laboratory at the U.C. San Diego.
They have this really remarkable facial expression technology that recognizes facial expressions, what facial expressions you're making. It also recognizes where you're looking, your head orientation. We're emulating all the major facial expressions, and then controlling it with the software that we call the Character Engine.
Let's tackle a slightly harder problem than what we saw in the last video. I have here x minus 3 over x plus 4 is greater than or equal to 2. So the reason why this is slightly harder is I now have a greater than or equal to.
If we assume this is negative, we get x has to be less than minus 4. If x is less than minus 4, in order for this equation to hold up, x also has to be greater than minus 11. And this is actually possible.
Minus 2 is the same thing as minus 2 times x plus 4 over x plus 4. This is minus 2 times 1. This is the same thing.
It's sort of cool that Top K via partitioning as just described works. It gets us the Top K values in a not sorted order. Right.
T(n/2) we're assuming is upper bounded by 4n/2, which is 2n, and this quantity T(n) we're assuming is less than 4n. Now this is a little bit of a mathematical abuse of induction. We really don't want this to be n here because our inductive step is going to assume this true for everything smaller than n and not equal to n but the reality is this is actually a tiny little bit less than n.
There's t(n-1) here but it's--with apologies, you can make these details all work out but it's a little irritating. With that caveat, we proceed. What we have is this is equal to n+n+2n, which is indeed 4n.
Determine whether 30/45 and 54/81 are equivalent fractions. Well, the easiest way I can think of doing this is to put both of these fractions into lowest possible terms, and then if they're the same fraction, then they're equivalent. So 30/45, what's the largest factor of both 30 and 45?
15 will go into 30. It'll also go into 45. So this is the same thing.
30 is 2 times 15 and 45 is 3 times 15. So we can divide both the numerator and the denominator by 15. So if we divide both the numerator and the denominator by 15, what happens?
2/3 is in lowest possible terms, or simplified form, however you want to think about it. Now, let's try to do 54/81. Now, let's see.
9 divided by 9 is 1, 9 divided by 9 is 1, so we get this as being equal to 6/9. Now, let's see.
6 is the same thing as 2 times 3.
9 is the same thing as 3 times 3. We could just cancel these 3's out, or you could imagine this is the same thing as dividing both the numerator and the denominator by 3, or multiplying both the numerator and the denominator by 1/3. These are all equivalent.
3 divided by 3 is just 1.
3 divided by 3 is 1, and you're left with 2/3. So both of these fractions, when you simplify them, when you put them in simplified form, both end up being 2/3, so they are equivalent fractions.
Welcome back.
Let's try to do this in a general way now. Right. So we call this procedure down heapify.
Now, in summary, revenue streams might take the form of a whole series of potential strategies. But what's interesting is inside of each revenue stream, you may have different pricing tactics. Let me say that again.
You probably already know everything is made up of little tiny things called atoms or even that each atom is made up of even smaller particles called protons, neutrons and electrons. And you've probably heard that atoms are small. But I bet you haven't ever thought about how small atoms really are.
How many cars' nuclei would you have to put into the box to have your one-foot-box have the same density of the nucleus?
Is it one car? Two? How about 100?
Find all of the factors of 120. Or another way to think about it, find all of the whole numbers that 120 is divisible by. So the first one, that's maybe obvious.
5 and 24. Let me clear up some space here because I think we're going to be dealing with a lot of factors. So let me move this right here.
Let's think about 8. I'll do the same process. Let's take 8 into 120.
Determine whether 394 is greater than or less than 397. Then write the expression that shows this using either this symbol or that symbol, and this is actually the less than symbol. We'll think a little bit more about how to remember that.
The next kind of graph we're going to look at is called a hypercube, and the graph is almost but not quite as cool as the name. We're going to define a hypercube for any number of nodes as long as that number of nodes is a power of 2. Here we have four nodes.
To generate the hypercube for n = 16, we can do this with a very interesting little trick. What we're going to do is we're going to take two hypercubes of size 8 and 8. Now 8 and 8 is going to be 16.
The decorative use of wire in southern Africa dates back hundreds of years. But modernization actually brought communication and a whole new material, in the form of telephone wire. Rural to urban migration meant that newfound industrial materials started to replace hard-to-come-by natural grasses.
In the '90s, my interest and passion for transitional art forms led me to a new form, which came from a squatter camp outside Durban. And I got the opportunity to start working with this community at that point, and started developing, really, and mentoring them in terms of scale, in terms of the design.
(Applause)
Welcome to the presentation on quadratic inequalities. Before we get to quadratic inequalities, let's just start graphing some functions and interpret them and then we'll slowly move to the inequalities. Let's say I had f of x is equal to x squared plus x minus 6.
Those are my very uneven lines. So the roots are x is equal to negative 3. So this is, right here, x is at minus 3y0 -- by definition one of the roots is where f of x is equal to 0.
Now what if we, instead of wanting to know where f of x is equal to 0, which is these two points, what if we wanted to know where f of x is greater than 0? What x values make f of x greater than 0? Or another way of saying it, what values make the statement true? x squared plus x minus 6 is greater than 0, Right, this is just f of x.
So just visually looking at it, what x values make this true? Well, this is true whenever x is less than minus 3, right, or whenever x is greater than 2. Because when x is greater than 2, f of x is greater than 0, and when x is less than negative 3, f of x is greater than 0.
Now is this -- this is the function we're working with -- is this less than 0? Well yeah, it is.
If you look at it visually it looks like this.
If you draw it visually and this is the parabola, this is f of x, the roots here are minus 7, 0 and 4, 0, we're saying that for all x values between these two numbers, f of x is less than 0. And that makes sense, because when is f of x less than 0? Well this is the graph of f of x.
And when is f of x less than 0? Right here. So what x values give us that?
Thought I would do a video on Communism, just because I've been talking about it a bunch in the history videos, and I haven't given you a good definition of what it means or a good understanding of what it means.
To understand Communism, let me just draw you a spectrum here.
So, I'm just gonna start with Capitialism. This is really just gonna be an overview. People can do a whole PhD thesis on this type of thing.
The modern versions of Communism are really kind of the brainchild of Karl Marx and Vladimir Lenin.
Karl Marx was a German philosopher in the 1800's who in his communist manifesto and other writings, kind of created the philosophical underpinnings for Communism.
And Vladimir Lenin who led the Bolshevik revolution and created essentially the Soviet Union.
He's the first person to make some of Karl Marx's ideas more concrete.
Let's say I have the indefinite integral 1 over the square root of 3 minus 2x squared. Of course I have a dx there. So right when I look at that, there's no obvious traditional method of taking this antiderivative.
So the derivative of x with respect to theta is equal to square root of 3 over square root of 2. Derivative of this with respect to theta is just cosine of theta, and if we want to write this in terms of dx, we could just write that dx is equal to square root of 3 over the square root of 2 cosine of theta d theta. Now we're ready to substitute.
93 00:04:47,64 --> 00:04:49,75 Now how can I simplify this?
Well, what's 1 minus sine squared of theta? That's cosine squared of theta. So this thing right here is cosine squared of theta.
Several statistics we can compute in a pretty straightforward way if the list L is sorted. Let's imagine that these are list of values that we're concerned about and I put little pointy things on it to say that this is now sorted from smallest to largest. If this L is sorted the minimum value is sitting here in the very first position--so it's L(₀), the maximum is sitting all the way at the end here--L(n-₁), midpoint is just the average of those two--so we can look up the minimum, the maximum add them together and divided by 2, and the median is just whoever is sitting in the middle of this list once it's sorted.
-CHAPTER I THE STRANGE MAN'S ARRlVAL The stranger came early in February, one wintry day, through a biting wind and a driving snow, the last snowfall of the year, over the down, walking from
Bramblehurst railway station, and carrying a little black portmanteau in his thickly gloved hand. He was wrapped up from head to foot, and the brim of his soft felt hat hid every inch of his face but the shiny tip of his nose; the snow had piled itself against his shoulders and chest, and added a white crest to the burden he carried. He staggered into the "Coach and Horses" more dead than alive, and flung his portmanteau down.
"Can I take your hat and coat, sir?" she said, "and give them a good dry in the kitchen?" "No," he said without turning. She was not sure she had heard him, and was about to repeat her question. He turned his head and looked at her over his shoulder.
Chirk, chirk, chirk, it went, the sound of a spoon being rapidly whisked round a basin. "That girl!" she said. "There!
"Will you get me some matches?" said the visitor, quite abruptly. "My pipe is out." Mrs. Hall was pulled up suddenly. It was certainly rude of him, after telling him all she had done.
For the most part he was quite still during that time; it would seem he sat in the growing darkness smoking in the firelight-- perhaps dozing. Once or twice a curious listener might have heard him at the coals, and for the space of five minutes he was audible pacing the room. He seemed to be talking to himself.
"Certainly," said the stranger, "certainly- -but, as a rule, I like to be alone and undisturbed. "But I'm really glad to have the clock seen to," he said, seeing a certain hesitation in Mr. Henfrey's manner. "Very glad."
"I should explain," he added, "what I was really too cold and fatigued to do before, that I am an experimental investigator." "Indeed, sir," said Mrs. Hall, much impressed. "And my baggage contains apparatus and appliances." "Very useful things indeed they are, sir," said Mrs. Hall.
"My reason for coming to Iping," he proceeded, with a certain deliberation of manner, "was ... a desire for solitude. I do not wish to be disturbed in my work. In addition to my work, an accident--"
"I thought as much," said Mrs. Hall to herself. "--necessitates a certain retirement. My eyes--are sometimes so weak and painful that I have to shut myself up in the dark for hours together. Lock myself up.
"Certainly, sir," said Mrs. Hall. "And if I might make so bold as to ask--"
"That I think, is all," said the stranger, with that quietly irresistible air of finality he could assume at will. Mrs. Hall reserved her question and sympathy for a better occasion. After Mrs. Hall had left the room, he remained standing in front of the fire, glaring, so Mr. Henfrey puts it, at the clock-mending.
At Gleeson's corner he saw Hall, who had recently married the stranger's hostess at the "Coach and Horses," and who now drove the Iping conveyance, when occasional people required it, to Sidderbridge Junction, coming towards him on his return from that place. Hall had evidently been "stopping a bit" at Sidderbridge, to judge by his driving. "'Ow do, Teddy?" he said, passing.
'Coach and Horses,'" said Teddy. "My sakes!" And he proceeded to give Hall a vivid description of his grotesque guest. "Looks a bit like a disguise, don't it?
I'd like to see a man's face if I had him stopping in my place," said Henfrey. "But women are that trustful--where strangers are concerned. He's took your rooms and he ain't even given a name, Hall."
"You don't say so!" said Hall, who was a man of sluggish apprehension. "Yes," said Teddy. "By the week.
-CHAPTER ill THE THOUSAND AND ONE BOTTLES So it was that on the twenty-ninth day of February, at the beginning of the thaw, this singular person fell out of infinity into Iping village. Next day his luggage arrived through the slush--and very remarkable luggage it was.
Fearenside's cart, while Hall was having a word or so of gossip preparatory to helping being them in. Out he came, not noticing Fearenside's dog, who was sniffing in a dilettante spirit at Hall's legs.
"Whup!" cried Hall, jumping back, for he was no hero with dogs, and Fearenside howled, "Lie down!" and snatched his whip. They saw the dog's teeth had slipped the hand, heard a kick, saw the dog execute a flanking jump and get home on the stranger's leg, and heard the rip of his trousering. Then the finer end of Fearenside's whip reached his property, and the dog, yelping with dismay, retreated under the wheels of the waggon.
"Coach and Horses." There was Fearenside telling about it all over again for the second time; there was Mrs. Hall saying his dog didn't have no business to bite her guests; there was
Huxter, the general dealer from over the road, interrogative; and Sandy Wadgers from the forge, judicial; besides women and children, all of them saying fatuities: "Wouldn't let en bite me, I knows";
"'Tasn't right have such dargs"; "Whad 'e bite 'n for, than?" and so forth. Mr. Hall, staring at them from the steps and listening, found it incredible that he had seen anything so very remarkable happen upstairs. Besides, his vocabulary was altogether too limited to express his impressions.
"He ought to have it cauterised at once," said Mr. Huxter; "especially if it's at all inflamed." "I'd shoot en, that's what I'd do," said a lady in the group. Suddenly the dog began growling again.
The chemist's shop in Bramblehurst could not boast half so many. Quite a sight it was. Crate after crate yielded bottles, until all six were empty and the table high with straw; the only things that came out of these crates besides the bottles were a number of test-tubes and a carefully packed balance.
"Perhaps you did. But in my investigations--my really very urgent and necessary investigations--the slightest disturbance, the jar of a door--I must ask you--"
You can turn the lock if you're like that, you know.
"A shilling--put down a shilling. Surely a shilling's enough?" "So be it," said Mrs. Hall, taking up the table-cloth and beginning to spread it over the table.
"My sakes!" said Henfrey. "It's a rummy case altogether. Why, his nose is as pink as paint!" "That's true," said Fearenside.
CHAPTER IV MR. CUSS INTERVlEWS THE STRANGER I have told the circumstances of the stranger's arrival in Iping with a certain fulness of detail, in order that the curious impression he created may be understood by the reader. But excepting two odd incidents, the circumstances of his stay until the extraordinary day of the club festival may be passed over very cursorily.
It was inevitable that a person of so remarkable an appearance and bearing should form a frequent topic in such a village as Iping. Opinion was greatly divided about his occupation. Mrs. Hall was sensitive on the point.
Cuss, the general practitioner, was devoured by curiosity. The bandages excited his professional interest, the report of the thousand and one bottles aroused his jealous regard. All through April and May he coveted an opportunity of talking to the stranger, and at last, towards Whitsuntide, he could stand it no longer, but hit upon the subscription-list for a village nurse as an excuse.
Cuss rapped at the parlour door and entered. There was a fairly audible imprecation from within. "Pardon my intrusion," said Cuss, and then the door closed and cut Mrs. Hall off from the rest of the conversation.
Cuss went straight up the village to
Bunting the vicar.
"Am I mad?" Cuss began abruptly, as he entered the shabby little study. "Do I look like an insane person?" "What's happened?" said the vicar, putting the ammonite on the loose sheets of his forth-coming sermon.
"Well?" "Give me something to drink," said Cuss, and he sat down. When his nerves had been steadied by a glass of cheap sherry--the only drink the good vicar had available--he told him of the interview he had just had.
"Well?" "No hand--just an empty sleeve. Lord! I thought, that's a deformity!
"That's all. He never said a word; just glared, and put his sleeve back in his pocket quickly. 'I was saying,' said he, 'that there was the prescription burning, wasn't I?'
'Empty sleeve?' 'Yes,' said I, 'an empty sleeve.' "'It's an empty sleeve, is it? You saw it was an empty sleeve?' He stood up right away. I stood up too.
"Had to say something. I was beginning to feel frightened. I could see right down it.
"Something--exactly like a finger and thumb it felt--nipped my nose."
Bunting began to laugh. "There wasn't anything there!" said Cuss, his voice running up into a shriek at the
"there." "It's all very well for you to laugh, but I tell you I was so startled, I hit his cuff hard, and turned around, and cut out of the room--I left him--"
Cuss stopped. There was no mistaking the sincerity of his panic. He turned round in a helpless way and took a second glass of the excellent vicar's very inferior sherry.
-CHAPTER V THE BURGLARY AT THE VlCARAGE The facts of the burglary at the vicarage came to us chiefly through the medium of the vicar and his wife. It occurred in the small hours of Whit Monday, the day devoted in Iping to the
"Janny," he said, over the rail of the cellar steps, "'tas the truth what Henfrey sez. 'E's not in uz room, 'e en't.
And the front door's onbolted." At first Mrs. Hall did not understand, and as soon as she did she resolved to see the empty room for herself. Hall, still holding the bottle, went first.
It was with the greatest difficulty that Mr. Hall and Millie, who had been roused by her scream of alarm, succeeded in getting her downstairs, and applying the restoratives customary in such cases. "'Tas sperits," said Mrs. Hall. "I know 'tas sperits. I've read in papers of en.
"Take a drop more, Janny," said Hall. "'Twill steady ye." "Lock him out," said Mrs. Hall. "Don't let him come in again. I half guessed--I might ha' known.
"Just a drop more, Janny," said Hall. "Your nerves is all upset." They sent Millie across the street through the golden five o'clock sunshine to rouse up Mr. Sandy Wadgers, the blacksmith.
Wodger, of the "Purple Fawn," and Mr. Jaggers, the cobbler, who also sold old second-hand ordinary bicycles, were stretching a string of union-jacks and royal ensigns (which had originally celebrated the first Victorian Jubilee) across the road. And inside, in the artificial darkness of the parlour, into which only one thin jet of sunlight penetrated, the stranger, hungry we must suppose, and fearful, hidden in his uncomfortable hot wrappings, pored through his dark glasses upon his paper or chinked his dirty little bottles, and occasionally swore savagely at the boys, audible if invisible, outside the windows. In the corner by the fireplace lay the fragments of half a dozen smashed bottles, and a pungent twang of chlorine tainted the air.
"I told you two days ago I wasn't going to await no remittances. You can't grumble if your breakfast waits a bit, if my bill's been waiting these five days, can you?" The stranger swore briefly but vividly.
"You told me three days ago that you hadn't anything but a sovereign's worth of silver upon you." "Well, I've found some more--" "'Ul-lo!" from the bar. "I wonder where you found it," said Mrs. Hall.
That seemed to annoy the stranger very much. He stamped his foot. "What do you mean?" he said.
"Stop!" with such extraordinary violence that he silenced her instantly. "You don't understand," he said, "who I am or what I am. I'll show you.
"Coach and Horses" violently firing out its humanity. They saw Mrs. Hall fall down and Mr. Teddy Henfrey jump to avoid tumbling over her, and then they heard the frightful screams of Millie, who, emerging suddenly from the kitchen at the noise of the tumult, had come upon the headless stranger from behind. These increased suddenly.
"Keep off!" said the figure, starting back. Abruptly he whipped down the bread and cheese, and Mr. Hall just grasped the knife on the table in time to save it. Off came the stranger's left glove and was slapped in Jaffers' face.
In another moment Jaffers, cutting short some statement concerning a warrant, had gripped him by the handless wrist and caught his invisible throat. He got a sounding kick on the shin that made him shout, but he kept his grip. Hall sent the knife sliding along the table to Wadgers, who acted as goal-keeper for the offensive, so to speak, and then stepped forward as Jaffers and the stranger swayed and staggered towards him, clutching and hitting in.
Mr. Hall, endeavouring to act on instructions, received a sounding kick in the ribs that disposed of him for a moment, and Mr. Wadgers, seeing the decapitated stranger had rolled over and got the upper side of Jaffers, retreated towards the door, knife in hand, and so collided with Mr. Huxter and the Sidderbridge carter coming to the rescue of law and order. At the same moment down came three or four bottles from the chiffonnier and shot a web of pungency into the air of the room.
Jaffers got up also and produced a pair of handcuffs. Then he stared.
"I say!" said Jaffers, brought up short by a dim realization of the incongruity of the whole business, "Darn it! Can't use 'em as I can see." The stranger ran his arm down his waistcoat, and as if by a miracle the buttons to which his empty sleeve pointed became undone.
"Ah! that's a different matter," said Jaffers. "No doubt you are a bit difficult to see in this light, but I got a warrant and it's all correct. What I'm after ain't no invisibility,--it's burglary.
There's a house been broke into and money took."
"Well?" "And circumstances certainly point--" "Stuff and nonsense!" said the Invisible "I hope so, sir; but I've got my instructions."
"Well," said the stranger, "I'll come. I'll come. But no handcuffs." "It's the regular thing," said Jaffers.
limply and empty in his hand. "Hold him!" said Jaffers, loudly. "Once he gets the things off--"
"Hold him!" cried everyone, and there was a rush at the fluttering white shirt which was now all that was visible of the stranger. The shirt-sleeve planted a shrewd blow in Hall's face that stopped his open-armed advance, and sent him backward into old Toothsome the sexton, and in another moment the garment was lifted up and became convulsed and vacantly flapping about the arms, even as a shirt that is being thrust over a man's head.
Jaffers clutched at it, and only helped to pull it off; he was struck in the mouth out of the air, and incontinently threw his truncheon and smote Teddy Henfrey savagely upon the crown of his head. "Look out!" said everybody, fencing at random and hitting at nothing. "Hold him!
Jaffers was struck under the jaw, and, turning, caught at something that intervened between him and Huxter in the melee, and prevented their coming together. He felt a muscular chest, and in another moment the whole mass of struggling, excited men shot out into the crowded hall. "I got him!" shouted Jaffers, choking and reeling through them all, and wrestling with purple face and swelling veins against his unseen enemy.
Jaffers cried in a strangled voice--holding tight, nevertheless, and making play with his knee--spun around, and fell heavily undermost with his head on the gravel. Only then did his fingers relax. There were excited cries of "Hold him!"
It grew to a climax, diminished again, and died away in the distance, going as it seemed to him in the direction of Adderdean. It lifted to a spasmodic sneeze and ended. Gibbons had heard nothing of the morning's occurrences, but the phenomenon was so striking and disturbing that his philosophical tranquillity vanished; he got up hastily, and hurried down the steepness of the hill towards the village, as fast as he could go.
Mr. Thomas Marvel was sitting with his feet in a ditch by the roadside over the down towards Adderdean, about a mile and a half out of Iping. His feet, save for socks of irregular open- work, were bare, his big toes were broad, and pricked like the ears of a watchful dog. In a leisurely manner--he did everything in a leisurely manner--he was contemplating trying on a pair of boots.
"H'm," said the Voice. "I've worn worse--in fact, I've worn none. But none so owdacious ugly--if you'll allow the expression.
"Where are yer? Alarmed, indeed!"
"Don't be alarmed," repeated the Voice. "You'll be alarmed in a minute, you silly fool," said Mr. Thomas Marvel.
"Where are yer?
Lemme get my mark on yer... "Are yer buried?" said Mr. Thomas Marvel, after an interval. There was no answer.
"It's not the drink," said the Voice. "You keep your nerves steady." "Ow!" said Mr. Marvel, and his face grew white amidst its patches.
"I'm--off--my--blooming--chump," said Mr. Marvel. "It's no good. It's fretting about them blarsted boots.
Whizz came a flint, apparently out of the air, and missed Mr. Marvel's shoulder by a hair's-breadth. Mr. Marvel, turning, saw a flint jerk up into the air, trace a complicated path, hang for a moment, and then fling at his feet with almost invisible rapidity. He was too amazed to dodge.
Whizz it came, and ricochetted from a bare toe into the ditch. Mr. Thomas Marvel jumped a foot and howled aloud. Then he started to run, tripped over an unseen obstacle, and came head over heels into a sitting position.
"That's all," said the Voice. "I'm invisible. That's what I want you to understand." "Anyone could see that.
"I'm invisible. That's the great point. And what I want you to understand is this-- "
"But whereabouts?" interrupted Mr. Marvel. "Here! Six yards in front of you."
"Oh, come! I ain't blind. You'll be telling me next you're just thin air.
"What, real like?" "Yes, real." "Let's have a hand of you," said Marvel, "if you are real. It won't be so darn out-of-the-way like, then--Lord!" he said, "how you made me jump!--gripping me like that!"
"Howjer manage it!
How the dooce is it done?" "It's too long a story. And besides--" "I tell you, the whole business fairly beats me," said Mr. Marvel. "What I want to say at present is this:
"Lord!" said Mr. Marvel. "I came up behind you--hesitated--went on-- " Mr. Marvel's expression was eloquent. "--then stopped.
(Lord!) Whatever you want done, that I'm most willing to do." CHAPTER X MR. MARVEL'S VlSIT TO IPlNG After the first gusty panic had spent itself Iping became argumentative.
Iping was gay with bunting, and everybody was in gala dress. Whit Monday had been looked forward to for a month or more. By the afternoon even those who believed in the Unseen were beginning to resume their
Haysman's meadow was gay with a tent, in which Mrs. Bunting and other ladies were preparing tea, while, without, the Sunday- school children ran races and played games under the noisy guidance of the curate and the Misses Cuss and Sackbut. No doubt there was a slight uneasiness in the air, but people for the most part had the sense to conceal whatever imaginative qualms they experienced. On the village green an inclined strong [word missing?], down which, clinging the while to a pulley-swung handle, one could be hurled violently against a sack at the other end, came in for considerable favour among the adolescent, as also did the swings and the cocoanut shies.
Huxter, appeared to undergo a severe internal struggle before he could induce himself to enter the house. Finally he marched up the steps, and was seen by Mr. Huxter to turn to the left and open the door of the parlour. Mr. Huxter heard voices from within the room and from the bar apprising the man of his error.
Huxter as assumed. He stood looking about him for some moments, and then Mr. Huxter saw him walk in an oddly furtive manner towards the gates of the yard, upon which the parlour window opened. The stranger, after some hesitation, leant against one of the gate-posts, produced a short clay pipe, and prepared to fill it.
-CHAPTER XI IN THE "COACH AND HORSES" Now in order clearly to understand what had happened in the inn, it is necessary to go back to the moment when Mr. Marvel first came into view of Mr. Huxter's window. At that precise moment Mr. Cuss and Mr. Bunting were in the parlour.
Jaffers had partially recovered from his fall and had gone home in the charge of his sympathetic friends. The stranger's scattered garments had been removed by Mrs. Hall and the room tidied up. And on the table under the window where the stranger had been wont to work, Cuss had hit almost at once on three big books in manuscript labelled "Diary."
"H'm--no name on the fly-leaf. Bother!--cypher. And figures." The vicar came round to look over his shoulder.
Cuss turned the pages over with a face suddenly disappointed. "I'm--dear me! It's all cypher, Bunting."
"Of course," said Mr. Bunting, taking out and wiping his spectacles and feeling suddenly very uncomfortable--for he had no Greek left in his mind worth talking about;
"yes--the Greek, of course, may furnish a clue." "I'll find you a place." "I'd rather glance through the volumes first," said Mr. Bunting, still wiping. "A general impression first, Cuss, and then, you know, we can go looking for clues."
And "Please shut that door," said Mr. Cuss, irritably.
A nautical term, referring to his getting back out of the room, I suppose." "I daresay so," said Cuss. "My nerves are all loose to-day. It quite made me jump--the door opening like that."
"I won't argue again," said Cuss. "We've thrashed that out, Bunting. And just now there's these books--Ah! here's some of what I take to be Greek!
"Odd!" said Mr. Henfrey. "Odd!" said Mr. Hall. "Says, 'Don't interrupt,'" said Henfrey.
"Like as not--" began Mrs. Hall. "Hsh!" said Mr. Teddy Henfrey. "Didn't I hear the window?" "What window?" asked Mrs. Hall.
Henfrey stopped to discover this, but Hall and the two labourers from the Tap rushed at once to the corner, shouting incoherent things, and saw Mr. Marvel vanishing by the corner of the church wall. They appear to have jumped to the impossible conclusion that this was the Invisible Man suddenly become visible, and set off at once along the lane in pursuit.
"Save yourself!" Mr. Bunting was standing in the window engaged in an attempt to clothe himself in the hearth-rug and a West Surrey Gazette. "Who's coming?" he said, so startled that his costume narrowly escaped disintegration.
From the moment when the Invisible Man screamed with rage and Mr. Bunting made his memorable flight up the village, it became impossible to give a consecutive account of affairs in Iping. Possibly the Invisible Man's original intention was simply to cover Marvel's retreat with the clothes and books. But his temper, at no time very good, seems to have gone completely at some chance blow, and forthwith he set to smiting and overthrowing, for the mere satisfaction of hurting.
The Invisible Man amused himself for a little while by breaking all the windows in the "Coach and Horses," and then he thrust a street lamp through the parlour window of Mrs. Gribble. He it must have been who cut the telegraph wire to Adderdean just beyond Higgins' cottage on the Adderdean road.
And after that, as his peculiar qualities allowed, he passed out of human perceptions altogether, and he was neither heard, seen, nor felt in Iping any more. He vanished absolutely. But it was the best part of two hours before any human being ventured out again into the desolation of Iping street. >
When the dusk was gathering and Iping was just beginning to peep timorously forth again upon the shattered wreckage of its Bank Holiday, a short, thick-set man in a shabby silk hat was marching painfully through the twilight behind the beechwoods on the road to Bramblehurst. He carried three books bound together by some sort of ornamental elastic ligature, and a bundle wrapped in a blue table-cloth. His rubicund face expressed consternation and fatigue; he appeared to be in a spasmodic sort of hurry.
"If you give me the slip again," said the Voice, "if you attempt to give me the slip again--" "Lord!" said Mr. Marvel. "That shoulder's a mass of bruises as it is." "On my honour," said the Voice, "I will kill you."
"I didn't try to give you the slip," said Marvel, in a voice that was not far remote from tears. "I swear I didn't. I didn't know the blessed turning, that was all!
"I'm a miserable tool," said Marvel. "You are," said the Voice. "I'm the worst possible tool you could have," said Marvel.
"I haven't the nerve and strength for the sort of thing you want." "I'll stimulate you." "I wish you wouldn't. I wouldn't like to mess up your plans, you know.
"Get on!" said the Voice. Mr. Marvel mended his pace, and for a time they went in silence again. "It's devilish hard," said Mr. Marvel.
"I tell you, sir, I'm not the man for it. Respectfully--but it is so--" "If you don't shut up I shall twist your wrist again," said the Invisible Man. "I want to think."
"Pleasant day," said the mariner. Mr. Marvel glanced about him with something very like terror. "Very," he said.
'em," said the mariner. "True likewise," said Mr. Marvel. He eyed his interlocutor, and then glanced about him.
"There's a story," said the mariner, fixing Mr. Marvel with an eye that was firm and deliberate; "there's a story about an Invisible Man, for instance." Mr. Marvel pulled his mouth askew and scratched his cheek and felt his ears glowing. "What will they be writing next?" he asked faintly.
"Ostria, or America?" "Neither," said the mariner. "Here." "Lord!" said Mr. Marvel, starting. "When I say here," said the mariner, to Mr. Marvel's intense relief, "I don't of course mean here in this place, I mean hereabouts."
"An Invisible Man!" said Mr. Marvel. "And what's he been up to?" "Everything," said the mariner, controlling
Marvel with his eye, and then amplifying, "every--blessed--thing." "I ain't seen a paper these four days," said Marvel.
"Iping's the place he started at," said the mariner. "In-deed!" said Mr. Marvel. And where he came from, nobody don't seem to know.
"Lord!" said Mr. Marvel. "But then, it's an extra-ordinary story. There is a clergyman and a medical gent witnesses--saw 'im all right and proper--or
"Lord!" said Mr. Marvel, looking nervously about him, trying to count the money in his pockets by his unaided sense of touch, and full of a strange and novel idea. "It sounds most astonishing." "Don't it?
Blimey." "But how 'bout this paper? D'you mean to say--?"
"Not a word of it," said Marvel, stoutly. The mariner stared, paper in hand. Mr. Marvel jerkily faced about.
"Don't you come bandying words with me," said Mr. Marvel. "Bandying words! I'm a jolly good mind--"
-CHAPTER XV THE MAN WHO WAS RUNNlNG In the early evening time Dr. Kemp was sitting in his study in the belvedere on the hill overlooking Burdock.
It was a pleasant little room, with three windows--north, west, and south--and bookshelves covered with books and scientific publications, and a broad writing-table, and, under the north window, a microscope, glass slips, minute instruments, some cultures, and scattered bottles of reagents. Dr. Kemp's solar lamp was lit, albeit the sky was still bright with the sunset light, and his blinds were up because there was no offence of peering outsiders to require them pulled down. Dr. Kemp was a tall and slender young man, with flaxen hair and a moustache almost white, and the work he was upon would earn him, he hoped, the fellowship of the Royal
"Spurted, sir," said Dr. Kemp. In another moment the higher of the villas that had clambered up the hill from Burdock had occulted the running figure. He was visible again for a moment, and again, and then again, three times between the three detached houses that came next, and then the terrace hid him.
And then presently, far up the hill, a dog playing in the road yelped and ran under a gate, and as they still wondered something- -a wind--a pad, pad, pad,--a sound like a panting breathing, rushed by. People screamed. People sprang off the pavement:
CHAPTER XVI IN THE "JOLLY CRlCKETERS"
The "Jolly Cricketers" is just at the bottom of the hill, where the tram-lines begin. The barman leant his fat red arms on the counter and talked of horses with an anaemic cabman, while a black-bearded man in grey snapped up biscuit and cheese, drank Burton, and conversed in American with a policeman off duty. "What's the shouting about!" said the anaemic cabman, going off at a tangent, trying to see up the hill over the dirty yellow blind in the low window of the inn.
For Gawd's sake!
'Elp!
'Elp!
'Elp!"
"Shut the doors," said the policeman. "Who's coming? What's the row?"
"Lemme go inside. Lock me in--somewhere. I tell you he's after me.
"You're safe," said the man with the black beard. "The door's shut. What's it all about?"
"Lemme go inside," said Marvel, and shrieked aloud as a blow suddenly made the fastened door shiver and was followed by a hurried rapping and a shouting outside.
"Hullo," cried the policeman, "who's there?" Mr. Marvel began to make frantic dives at panels that looked like doors. "He'll kill me--he's got a knife or something.
"Don't you be in too much hurry about that door," said the anaemic cabman, anxiously. "Draw the bolts," said the man with the black beard, "and if he comes--" He showed a revolver in his hand. "That won't do," said the policeman; "that's murder."
"Good Lord!" said the burly barman. "There's the back! Just watch them doors!
"Have you fastened it?" asked the first cabman. "I'm out of frocks," said the barman. The man with the beard replaced his revolver.
CHAPTER XVII DR. KEMP'S VlSITOR Dr. Kemp had continued writing in his study until the shots aroused him. Crack, crack, crack, they came one after the other.
"Hullo!" said Dr. Kemp, putting his pen into his mouth again and listening. "Who's letting off revolvers in Burdock? What are the asses at now?"
"Let me get up," said Kemp. "I'll stop where I am. And let me sit quiet for a minute." He sat up and felt his neck.
"Griffin?" said Kemp. "Griffin," answered the Voice. A younger student than you were, almost an albino, six feet high, and broad, with a pink and white face and red eyes, who won the medal for chemistry."
"I am confused," said Kemp. "My brain is rioting. What has this to do with Griffin?" "I am Griffin."
"It's horrible!" said Kemp. "How on earth--?" "It's horrible enough.
"Or silly," said Kemp, and knuckled his eyes. "Give me some whiskey. I'm near dead." "It didn't feel so.
"Nonsense," said the Voice. "It's frantic." "Listen to me."
"Never mind what you've demonstrated!--I'm starving," said the Voice, "and the night is chilly to a man without clothes."
"Food?" said Kemp. The tumbler of whiskey tilted itself. "Yes," said the Invisible Man rapping it down.
The whole business--it's unreasonable from beginning to end." "Quite reasonable," said the Invisible Man.
"Perfectly reasonable." He reached over and secured the whiskey bottle. Kemp stared at the devouring dressing gown.
"Is he invisible too?" "No." "Well?" "Can't I have some more to eat before I tell you all that?
"I'll see what there is to eat downstairs," said Kemp. "Not much, I'm afraid." After he had done eating, and he made a heavy meal, the Invisible Man demanded a cigar.
"But how was it all done?" said Kemp, "and how did you get like this?" "For God's sake, let me smoke in peace for a little while! And then I will begin to tell you." But the story was not told that night.
"Well, have my room--have this room." "But how can I sleep? If I sleep--he will get away.
"Why not?" The Invisible Man appeared to be regarding Kemp. "Because I've a particular objection to being caught by my fellow-men," he said slowly.
Most of what we do early on when we first learn about calculus is to use limits. We use limits to figure out derivatives of functions.
In fact, the definition of a derivative uses the notion of a limit. It's a slope around the point as we take the limit of points closer and closer to the point in question. And you've seen that many, many, many times over.
And in this video I'm just going to show you what
l'Hoptial's rule says and how to apply it because it's fairly straightforward, and it's actually a very useful tool sometimes if you're in some type of a math competition and they ask you to find a difficult limit that when you just plug the numbers in you get something like this. L'Hopital's rule is normally what they are testing you for. And in a future video I might prove it, but that gets a
Limit as z approaches 0 of x is also equal to 0. The limit of the derivative of sine of x over the derivative of x, which is cosine of x over 1-- we found this to be equal to 1. All of these top conditions are met, so then we know this must be the case.
Alright, so not too much code. First we call a new XMLHttpRequest, then we specify the open method with the parameters GET, weapon.json, and true since we want the call to be asynchronous and then we set the onload function to be our parsing code from before and finally we kick-off the request with xhr.send. Now, if we open this in chrome's developer tools, we can see that we actually do make this request for weapon.JSON, method get and it's successful status, and it takes about thirteen milliseconds.
Some of the revenue model questions: What is it my customers are paying for? What's the value?
Welcome to level three exponents. Let's get started. So if I asked you what four to the one / two power is, your immediate inclination is to view this probably as like a multiplication problem and try to multiply it somehow or add them or something.
So we know that nine to the one / two is equal to three. Well what do you think nine to the two / three is equal to? Well, it turns out that this is equivalent to nine to the -- oops,
eight over twenty-seven to the negative one / three. Immediately when we see that negative, we want to just flip it. So we'll say that equals twenty-seven over eight to the one / three, and that equals twenty-seven to the one / three over eight to the one / three.
The last piece I want to talk about for research is intellectualy property. There are great law firms who can give you tutorials. There is plenty of stuff on the web.
Because you're never going to have somebody push a bag of money at you across the table over a series of Powerpoint slides. In fact if an investor is interested, and you are now in meeting 2, 3, or 4, and they say listen for us to really proceed we need to have you open the hood and let us or a consultant take a look, the next question to ask is well if we do that, and it meets these following criteria, is there an investment or not? If the answer is yes then you can make them, or at least require an NDA, because they have gone down the path of interest with you and are serious.
Now, if President Obama invited me to be the next Czar of Mathematics, then I would have a suggestion for him that I think would vastly improve the mathematics education in this country. And it would be easy to implement and inexpensive. The mathematics curriculum that we have is based on a foundation of arithmetic and algebra.
When I look at an existing market, it's clear that if you've match those market needs, you could be achieving profitability the soonest. If you're doing a clone market--that is copying a US business model in a foreign country, that probably is the second closest to immediate profitability because you know the market exist that you just need to implement it in your local country.
Resegmented market--well, that's probably somewhere in between existing in clone and new because you not only have to understand the market you have to understand the customer's specific needs or low-cost needs. But the longest time to profitability is a new market. You have a vision that you understand what the future might look like, but the market just hasn't adapted yet and that might take years.
We're asked to shade 20% of the square below. Before doing that, let's just even think about what percent means. Let me just rewrite it.
And if you're familiar with the word century, you might already know that cent comes from the Latin for the word hundred. This literally means you can take cent, and that literally means 100. So this is the same thing as 20 per 100.
The deadliest weapon on the battlefield: The Sniper After having chased the enemy, nothing else matters.
Some scenes are dramatically recreated. <b> Video Editing, Translation and Sync Subtitles by M ª × Castro </ b>
Ramadi, Iraq, 2005. When we went to Ramadi,
IED rate was about 95-100 IEDs in a week. Our mission was to get people planting IED'S Soldiers fighting in Iraq has a motto:
Be polite, be professional and have a plan to kill everyone you meet. <b> If you're looking for, and you are considered a bad guy, </ b> <b>'il be there to kill him. </ b> <b> Sniper: 1st Sergeant James Gilliland. </ b> <b> the greatest long-distance shot with a rifle cal.
7.62 mm </ b> <b> 1400 meters </ b> Once the enemy makes one step and crosses my line, then he comes to my world. it becomes my target.
Gilliland and Shadow Team, with ten units are army snipers, watching the activity of insurgents from a point across the city. They accumulate 276 deaths in six months. One of the main techniques we use to find our next targets is directly related to deer hunting in Turkey.
Gilliland demands two things to your team: Many shots with their weapons and shot the bodies. <b> shots at the "center of mass". </ b> The center of mass is slightly below the chest.
We often hear - "naswas" which is "Sniper" in Iraq And we hear about the intercoms of mosques and other things. Always alerting them that we were hunting,
"Hey, send those guys go down again" right before I push the button to talk I heard a shot and he fell
"Man fallen fallen man!" "We reached the hospital!" we were watching and then we heard on the radio: "fallen man." someone just shot by an enemy sniper. looking everywhere, trying to find that sniper.
Gilliland and saw the gunman in the window of one of the upper floors on the fourth floor, a position, a single person on a balcony I could clearly see a long-barreled rifle, a Kalashnikov. We knew from our building to the hospital were 1250 meters or seven-tenths of a mile from our vantage point.
The distance of 13 soccer fields and means about 500 meters beyond the maximum effective range of the M24 Gilliland. The intention was not to make a perfect shot, a shot "clinical" at that distance, wanted to suppress the target
The M24 has a great range using the telescope loopholed Alpha N3 Caught adjusting the telescope in 1000-dot to compensate for bullet drop. You assigns a number to the amount of hundreds of meters that will shoot.
Gililland 3.60cm must aim above the target Also in this case had to think of the wind, Pushing the rotation, making the projectile falls
Gilliland "useless" 2.40cm to the left of the goal to compensate a light wind that slows down. This setting is known as "Kentucky Compensation." The lines are totally off target. was comfortable, had good view and did the shooting
Vietnam 1969 A Marine Sniper faces hundreds of soldiers, enemy less than 100 yards away. I have the crosshairs of my scope right on his forehead, and rapidly move from one to the other, pow pow, pow!
16 shots in 16 different positions, and can do no wrong ... <b> Or you die! </ b> Precision Weapons Section Quantico, Virginia. Life of Marine Snipers Rifles starts here.
This is the sniper rifle he M40X is basically the father the M40A3, which is the most modern sniper rifle that we use today. this weapon is harder to shoot and that's one of the reasons why guys like Chuck Mawhinney became legends, received only this rifle and basic unbelievably, did so much devastation on enemy In <b> target. </ b> <b> Shoot when ready. </ b> <b> Say goodnight guy </ b> <b> 16 Shots 16 Dead </ b>
Mawhinney main weapon:
Sniper Rifle M40 mortal to 1094 meters distance of 11 football fields. You hit someone out there that distance, This was towards the end, and we saw a lot of people standing in the open, long distances.
Mawhinney is on a collision course with hundreds of North Vietnamese soldiers. winds were approaching our position We had a large NVA force reported by aircraft Coming toward our position and they said:
"So grab your partner and go check on the river tonight" do not let them cross it. Recarregem their weapons and go!
In most snipers are fighting with targets of 300 to 1,000 meters
Mawhinney can tackle multiple targets within 100 meters of his position Our range is our security, our foothold. I can shoot you to 1,000 meters, and you will not even me
Mawhinney exchange their M40 bolt-action to your secondary weapon: the M14 semi-automatic.
I knew I had to do it as fast as you can The more we delay, the more I find out where we were, and what was happening
The M14 has a charger and is semi-automatic. it automatically feeds. That's less time for a new round in the chamber and ready to fire. Night falls.
Mawhinney and his Observer lurk in its final position shooting or "FFP". Hide overlooking the shallowest part of the river, the meeting point. when it is hidden is, choosing a good place to go shoot. I want a good view of what I want to shoot, and I want a good escape route and evasion.
The river runs 9:00 to 03:00, giving a natural barrier between Mawhinney and the enemy. a bank of mud at 12:00 protects them from small arms fire, and enables a clear field of vision.
Twigs and leaves at 3:00 and 9:00 give good coverage. The Observer is responsible for security in this sector. If the mission is compromised, the escape route of the Marines is 5:00.
Mawhinney's Eyes: A bezel AN/PVS-2 Starlight. the first night vision system activated by ambient light All in a green tone by Starlight and things light will appear brighter than others. a face, skin and hands, they light through the telescope. have to have some kind of external light to her work.
Mawhinney sweeps the river behind any sign of the enemy. So we lay on that beautiful night for a long time and half hours after the movement have the other side. Someone enters the river and starts to come through straight right on top of us.
Mawhinney expects the NVA appear. He mentally visualizes your field of fire. The death zone is the size of a football field.
"What am I gonna do if they come here?" "How can I kill them here?" "How to put them in a position to eliminate them?"
Mawhinney assigns distances for your shots closer and more distant. is in a position where he does not have time to do calculations and obtaining a result does not know the distance ranges. Chuck was not lying there to make calculations. he "had the notion." We call it "Science of dumb hunch"
Mark Mawhinney their "points of power" in the 50m telescope to the point of impact. in 45 minutes to an hour here they come! He is in the middle of nowhere by yourself. has its friendly forces to his rear in front of the enemy, he is in the middle. If they run and cross the river, has no chance to escape
16 shots in 30 seconds.
Mawhinney disappears into the jungle. Many things happen when you do one shot. It's like a musical symphony.
AN PVS-10, our new telescopes are using an HDTV. then, their targets were not as easily defined that's another thing that makes him amazing, the amount of enemies he overthrew. with the overcast sky was a little light that storm, at 50-60 meters, it was really hard to see. 16 shots in the head, that's all I had to do. The average human has 90 inches from the waist up.
He fired at a target too narrow for a Sniper was night and were not stopped targets, were moving 25 cm hit that moved from left to right, up and down. have to make 16 different times <b> 16 shots in 16 different positions </ b> <b> and can not err </ b> <b> or you die! </ b>
The M14 Mawhinney is semi-automatic. He hits a target every 1.9 seconds Prior planning prevents errors in action.
The M40 bolt-action has the capacity to 5 cartridges
The M14 is semi-automatic and has a capacity of 20 bullets. More quick shots means more enemy soldiers killed. we must speak of the importance of a thing called "violence of action." massive firepower, you against me, I'll take you down with huge fire power, very closely.
The head of 25 cm arms up with their AK 47's that were carrying. and are wading through water. walking in a column, each with 10m range were close enough to see each other and give signs, and far enough for a machine gun attack Chuck in approximately 30 seconds, fired 16 times.
After 30 seconds, 16 new human floats down the river. With this weapon more modern 7.62 mm, semi-auto and this amazing telescope we simulate everything. When you give the command "up", hit the first target and you have 30 seconds.
On 16 shots, I want 16 targets. Shooter, pronto. Wait."
"Will not cross it."

"Kill one man, terrorize a thousand." Place your team and away team using M40A3 RPG out of its effective range. He tightens the siege on the death zone with a single devastating shot.
A target of 25 cm at a distance of 5 football fields. "I'll get him." I aimed right at the top of the neck, and fired.
Snipers are multipliers in combat. He sent in the entire area.
19 deaths. Place helps Marines to advance further into the city. But the battle continues to do damage. his shot is lethal and harder to come by.
At 600 meters, represents about 1 mil-dot 21 inches. The velocity of the individual from the other side of the street Was at 4.5 mil-dot, which is a very big advantage. and was actually using the telescope points
Traveling at 2550 m / s, the projectile 175 grams enters the cranial cavity destroying the brainstem to a millisecond. in my bezel I witnessed that shot This piece of shit fell, the gun fell, no movement. it was lethal And never left that position 30 days, 32 deaths.
At 600 meters, a fall of 10 or 20 degrees in temperature can increase the density of air, causing the bullet drop at 15 cm away from the target For a sniper can be the difference between life and death. Now, I will show it to the wind.

The 14th Compania Fox Marines patrol a road in Lutayfiyah. Your mission: Find bombs and insurgent
Tucker saw a body of an animal on the road that was not there the night before My scope is expanded on it we saw a little sparkle out and be thought a thread We think of what happened before, the insurgents are planting IEDs in dead animals, playing on the side of the road
"We have an IED 20 meters after the bend"
IED! "Understood, we are establishing a perimeter" They isolate the area near the IED
"Ready" "vai, vai, vai" When we saw the glow coming out of the wires we feel good, like, "Hey, we did our job"
'il take care of this IED, disarm him, and no one gets hurt
"We're covering the rear!" "Men of Sergeant Rodrigues what is your situation?" "All clear!"
Reichert adjusts its power or "Dopes the telescope" to 10 +2: some 1000 meters in 2 minutes adjustment The Marines on the ground to fight his way back to the city and find cover in an abandoned school are much smaller in number All other insurgents in the city heard the shots

What breadth first search does is it always expands out in levels. So h expands into i and j, one and the other first, and then one of the other of these has expanded but with only one level, and before we go any deeper, 3 has nodes, j's nodes get expanded next, and only after everything distance 2 away from h has been expanded, will o all get its chance.
What we used to believe for strategy is that you start any company with an operating plan and a financial model. What's an operating plan? Well, it's the business plan.
Let's say we had to figure out how many times 16 goes into 1,388. And what I want to do is first think about how we traditionally solve a problem like this, and then introduce another method that allows for a little bit more approximation. So traditionally you would say, well sixteen does not go into one any times, so then you move over one spot, and then how many times does it go into 13?
And you might try nine first, and I'll do all my arithmetic on the right side so you ight say 16 times 9, 6 times 9 is 54, 1 times 9 is nine, plus five is fourteen, so that's a hundred and forty-four times, but still, that's larger than a 138.
So it's going to go into it eight times, eight times is going to be less than 138, so we stick the eight here. And notice to do this little trial and error here I had to make sure I got the right exact answer with that eight right over here.
Then when we say eight times six is 48, and then eight times one is eight, plus four, is twelve.
So eight times sixteen is 128, so when I subtract, I get the remainder from 138, so I get a remainder of eight minus eight is zero, 3-2 is 1, and these cancel out.
So I have a remainder of ten, but I still have a remainder of eight so I bring that down and I have a hundred and eight. And then I do the same thing again. Let me get rid of this so everyone doesn't get distracted, we say how many times does sixteen go into 108?
And you can approximate and say well, it's definitely not eight times, eight times is 128, is it, maybe, seven times?, and you might do a little math on the side, so its 16 times 7, 6 times 7 is 42, one times 7 is seven plus four is eleven, so you get 112.
So that's still to large, so that's going to be six, but notice, we had to do this little sidework on the side right over here to come up--to realize it wasn't seven, we know six is the largest how many times it can go into 108 without going over it.
So 6 times 6 is 36,carry the three and regroup the 3 depending on how you think about it.
6 times 1 is 6 plus 3 is 9, plus six is -- or plus six is nine/ Then you subtract again, eight minus six is two, and then you could just say ten minus nine is one, or you can even borrow, you could make this ten and then this goes away, 10-9 is 1, so then you have 12.
So in understanding our customer segments, it was really helpful to pictures up and as we build an archetype of who our three potential customer segments are.

One thing that I've always enjoyed about being in the presence of the bhaktis, in the bhaktas is that rarely you find so (much) egotism, you see In the state of surrender and devotion you don't see so much egotism it is so surrendered, humility, it's so touching so deep, so profound, you see More arrogance is found, and pride, amongst the Jnanis, you see because more of this is more the sort of psychological, intellectual type and so there is more feeling well, you know "I am It", you know...
"I am silent..I am more silent than you" This type of thing, so much more room for egotism
Welcome to the presentation on multiplying decimals. Let's get started. So I think you'll find out that multiplying decimals is not a lot more difficult than just multiplying regular numbers.
One, two, three, four. So there are four numbers behind the decimal point in the problem I did, and I just count here. One, two, three, four.
Nine times one is nine.
Nine times five is forty-five. And in the zeros place you put a zero and then zero times everything is zero. Right?
One times one is one. And one times five is five. And now we add it all.
One, two, three, four. So one, two, three, four. So the decimal will go here.
Two times three is the same thing as three times two. So one point zero nine times five point one is the same thing as five point one times one point zero nine. So let's just multiply this out.
One times zero is zero.
One times one is one. Put a zero here.
Five times nine is forty-five.
Carry the four.
Five time zero is zero. Plus four is four. Five times one is five.
Nine, five, five, five. Now I'm at the point that I can actually pay attention to the decimal points. How many numbers are behind the decimals?
Carry the two.
Fve times seven is thirty-five. Plus two is thirty-seven.
Bring down the seven, carry the three.
Five times zero is zero. Plus three. So it's three hundred and seventy-five, ignore that blob.
One times five is five.
One times seven is seven. Ignore that. Now we add.
Seven plus five is twelve. One plus three plus seven is eleven. So we got our answer, now we just have to count the decimals.
We say one, two, three, four, and we need one more number behind the decimal point, so we add a zero here. And then we put the decimal point. See what I just did?
RSA Animate Iain McGilchristThe Divided Brain and the Making of the Western World The division of the brain is something neuro-scientists just don't like to talk about anymore it enjoyed a sort of popularity in the 60s and 70s, after the first split-brain operations and it led to a sort of popularization which has since been proved to be entirely false.
In the last video, we talked about how the Serbians were able to hold back the Austro-Hungarians at the beginning of World War I. But eventually they had to give in. They were essentially -

From the 16th to the 18th? Yes. But the exhibition will last for only three days.
- What's up? - Hey. Ho-jin, I'm leaving now.
3rd place was the wild horse, Bak Joon-woo of Oilbank. Fourth was Hwang Dae-jin. Feeling good, huh?
It's the 7th head pin, so slow it down. He wants to kill himself! He's scaring me!
Yae-joo. Hi, Eun-soo. Is Dae-jin really alright?
Yae-joo, too. Hurry and eat. Dae-jin.
- After you woke up... - My name is Hwang Ho-jin. Any other symptoms besides headaches?
Yae-joo. Dae-jin is still sick. He's doing this because he's still mentally unstable.
Yae-joo. Where can I go? I'm not going anywhere.
For Eskimos, when someone they love dies, they gather and talk about that person for five days. While they talk, they erase their memories of that person. Afterwards, they never talk about that person again.
Does it show? Yae-joo. I'm okay.
- The world... - Hi. abandoned me. Even the skies.
Since Eun-soo will be with him. I'm also a happy person. I'll be able to see Eun-soo forever.
Given what we have build up so far, we can actually use the pieces to build a heap from scratch. We have the heap structure. In this case, with seven nodes and we filled them in with this random two digit numbers and it's not heap at the moment, but we can make the heap property be satisfied and this the way we're going to do it.
I want you to analyze the running time of Dijkstra and ideally, I would just ask you but given that you can't answer me directly, I'm going to have to make this a multiple choice question. And it turns out that you don't have enough information to answer it.
Let's get going with more examples of function problems, and hopefully as we keep doing this, you're going to get the idea of how all this stuff works. So let's do another problem. I'll use green this time.
And a couple here, like this.
Sorry if you're getting bored while I draw this graph. I should really have some type of tool so that the graphs just show up. Let me draw a-- let's say that-- let me draw this function.
I'm going to create another definition for g of x this time. Let's say that g of x-- oh whoops, I was trying to write in black-- let's say that g of x is equal to f of x squared plus f of x plus 2. So now, in this case, what is g of-- let's pick a random number-- what is g of minus-- no, let's pick a, let's say-- what is g of minus 2?
So what's f of 0? f of 0 is 0. When x is equal to 0-- f of 0 is 0 so that's 2 plus 0-- so g of negative 2 is equal to 2. An interesting thing, you might want to make problems like this for yourself and keep experimenting with different types of functions, and a very interesting thing would actually be to graph g of x, and actually that's a good idea, I think.
Our second guest is Tina Eliassi-Rad, a computer science professor at Rutger's University.
She studies data mining and machine learning with a special emphasis on the data that comes up in network science. There's been an explosion in interest in studying networks and network science. If you could comment a little bit about where Big Data is coming from.
Lets say we have one ray over here that starts at point A and then goes through point B, and so we could call this ray (we could call, let me draw that a little bit straighter) we could call this ray AB. Ray AB
starts at A or has a vertex at A and lets say that there is also a ray AC. So lets say that C is sitting right over there and then i can draw another ray that goes through C, so this is ray AC. and what's interesting
about these two rays is that they have the exact same vertex. (they have the exact same vertex at A)
and in general what we have when we have two rays with the exact same vertex, you have an angle. and
you've probably, you're probably already reasonably familiar with the concept of an angle which i believe comes from the latin for corner, which makes sense this looks a little bit like a corner right over here that we see at point A and, but the geometric definition, or the one you are more likely to see
is when two rays share a common vertex. and that common vertex is actually called the vertex of the angle.
so A is vertex. Not only is it the vertex of each of these rays, ray AB and ray AC, it is also the vertex of, of the angle. so the next thing i want to think about is how do we label, how do we label an angle
So now we have a general idea what an angle is and how we denote it with symbols, it does not look like all angles look the same. Some are more open than others So for example, let us take two angles here, angle BAC, and let's say over here, I have angle XYZ when you look at these angle XYZ is more open while this angle is more closed, compared to the other angle when we measure angles, we must measure it on how open or closed they are.
We've already learned that cellular respiration can be broken down into roughly three phases.
By the way just as on the side, I've been talking about problem or need as part of the product. And I just want you to remember it's kind of interesting to differentiate between solving a problem or if somebody who has an accounting problem or a word processor or they can now use Google docs versus Microsoft Word versus a need. What's a need?
>> Now that we have the tiledJSON loaded, we need to parse it. So, let's take a closer look at the structure of this file. There's a few things that should interest you about this file, right away.
Finally, we have a separate section of the JSON file devoted to the layers that you've defined. Now, each layer that exists has a data element, which actually lists out a large, very large, ludicrously large array of integer values that represent each tile that you've placed on this layer.
>> Basically, all we have to do is once we have the map object, we go through and cache width, height, tile width, tile height. And then, we actually compute the pixel size of x and y by multiplying the number of tiles times the tile size. Once this is done, we can actually set fully loaded to true allowing any external processing to work on this object.
A bit of a classic implicit differentiation problem is the problem y is equal to x to the x. And then to find out what the derivative of y is with respect to x. And people look at that, oh you know, I don't have just a constant exponent here, so I can't just use the power rules, how do you do it.
And then we're going to add that to, plus the derivative of the natural log of x. That's fairly straightforward, that's 1/x times x to the x.
And of course the left hand side of the equation was just 1/y dy/dx. And we can multiply both sides of this now by y, and we get dy/dx is equal to y times all of this crazy stuff-- x to the x times the natural log of x plus 1 times the natural log of x plus 1/x times x to the x. That's x to the negative 1.
step up you'll be shocked when I spit and start static I'll rip your style and add it to my long list of patents while you were busy digging ditches and burning bridges I'm pumping out inventions stacking riches so go back to your pigeons you're a geek plagued by OCD you never had sex but you sure got screwed by me
Shantanu: We tell teachers that you shouldn't be the sage on the stage but you should actually be the guide on the side. But they really don't have the tools that are necessary to really make that possible today.
One of the big differences with Khan Academy is that we're not trying to just replicate the existing systems using technology to augment the way existing instruction is done.
We're fundamentally thinking about reinventing instruction.
Sal:
We've gotten letters from teachers who said,
"Hey, you've already given the lecture on L'Hopitals rule or the unit circle."
Instead of me giving the basic lecture on that and then assigning homework, we flip the model.
I'm assigning the lecture for them to watch at home and then they can watch what I assign.
But then if they have some questions they can re-mediate and watch stuff that was taught in previous sections.
Or if they're bored they can move ahead and go as advance as they want.
Then when they go into the classroom they can actually do problems, they should do their homework in the classroom. We have this teacher dash board right now where it shows all of the students and all of the concepts. Within a glance a teacher can see whose mastered what, who's struggling with what, where each student is in their development and learning.
Sal: To roll out it's actually super simple, it's all web based, it's all free, so literally if a school has internet connectivity and has computers, any type of computer, they're ready to start 1 + 1 and get to Calculus.
I'd like to show you a video of some of the models I work with. They're all the perfect size, and they don't have an ounce of fat.
And they're scientific models? (Laughs) As you might have guessed, I'm a tissue engineer, and this is a video of some of the beating heart that I've engineered in the lab.
One of the key technologies that's really important is what's called induced pluripotent stem cells. They were developed in Japan pretty recently. Okay, induced pluripotent stem cells.
By combining tissue engineering techniques with microfluidics, the field is actually evolving towards just that, a model of the entire ecosystem of the body, complete with multiple organ systems to be able to test how a drug you might take for your blood pressure might affect your liver or an antidepressant might affect your heart. These systems are really hard to build, but we're just starting to be able to get there, and so, watch out. But that's not even all of it, because once a drug is approved, tissue engineering techniques can actually help us develop more personalized treatments.
Thank you. (Applause)
CHAPTER XVII The Freeman's Defence There was a gentle bustle at the Quaker house, as the afternoon drew to a close. Rachel Halliday moved quietly to and fro, collecting from her household stores such needments as could be arranged in the smallest compass, for the wanderers who were to go forth that night.
"And when we get to Canada," said Eliza, "I can help you. I can do dress-making very well; and I understand fine washing and ironing; and between us we can find something to live on."
"Yes, Eliza, so long as we have each other and our boy.
Eliza, if these people only knew what a blessing it is for a man to feel that his wife and child belong to him!
"But yet we are not quite out of danger," said Eliza; "we are not yet in Canada." "True," said George, "but it seems as if I smelt the free air, and it makes me strong." At this moment, voices were heard in the outer apartment, in earnest conversation, and very soon a rap was heard on the door.
"Ay, ay," said Phineas, nodding his head to Simeon; "thou seest, Simeon, how it will work." "I see," said Simeon, sighing; "I pray it come not to that."
"I don't want to involve any one with or for me," said George. "If you will lend me your vehicle and direct me, I will drive alone to the next stand. Jim is a giant in strength, and brave as death and despair, and so am I."
"Ah, well, friend," said Phineas, "but thee'll need a driver, for all that. Thee's quite welcome to do all the fighting, thee knows; but I know a thing or two about the road, that thee doesn't." "But I don't want to involve you," said
"Involve," said Phineas, with a curious and keen expression of face, "When thee does involve me, please to let me know." "Phineas is a wise and skilful man," said Simeon.
"Would not even you, sir, do the same, in my place?" "I pray that I be not tried," said Simeon; "the flesh is weak." "I think my flesh would be pretty tolerable strong, in such a case," said Phineas, stretching out a pair of arms like the sails of a windmill.
"If man should ever resist evil," said Simeon, "then George should feel free to do it now: but the leaders of our people taught a more excellent way; for the wrath of man worketh not the righteousness of God; but it goes sorely against the corrupt will of man, and none can receive it save they to whom it is given. Let us pray the Lord that we be not tempted."
"And so I do," said Phineas; "but if we are tempted too much--why, let them look out, that's all." "It's quite plain thee wasn't born a Friend," said Simeon, smiling.
"Well," said George, "isn't it best that we hasten our flight?" "I got up at four o'clock, and came on with all speed, full two or three hours ahead of them, if they start at the time they planned. It isn't safe to start till dark, at any rate; for there are some evil persons in the villages ahead, that might be disposed to meddle with us, if they saw our wagon, and that would delay us more than the waiting; but in two hours I think we may venture.
"Thee'll much oblige us, friend George, to say no more about that. What we do we are conscience bound to do; we can do no other way. And now, mother," said he, turning to Rachel, "hurry thy preparations for these friends, for we must not send them away fasting."
"Is not that the way thee feels, George?" "It is so indeed," said George,--"as well as I could have written it myself." "Then, hear," said Simeon:
"O, thank you; you are too kind," said Eliza. "Come, Ruth, sit down to supper," said Rachel. "I couldn't, any way.
"Here are the two buffaloes," said Rachel. "Make the seats as comfortable as may be; it's hard riding all night." Jim came out first, and carefully assisted out his old mother, who clung to his arm, and looked anxiously about, as if she expected the pursuer every moment.
"I rather think I haven't," said Jim, throwing open his broad chest, and taking a deep breath. "Do you think I'll let them get mother again?" During this brief colloquy, Eliza had been taking her leave of her kind friend,
"Yes; what news--they coming?" "Right on behind, eight or ten of them, hot with brandy, swearing and foaming like so many wolves." And, just as he spoke, a breeze brought the faint sound of galloping horsemen towards them.
"this is one of our old hunting-dens. Come up!" Phineas went before, springing up the rocks
Whoever comes here has to walk single file between those two rocks, in fair range of your pistols, boys, d'ye see?" "I do see," said George! "and now, as this matter is ours, let us take all the risk, and do all the fighting."
"Thee's quite welcome to do the fighting, George," said Phineas, chewing some checkerberry-leaves as he spoke; "but I may have the fun of looking on, I suppose. But see, these fellows are kinder debating down there, and looking up, like hens when they are going to fly up on to the roost. Hadn't thee better give 'em a word of advice, before they come up, just to tell
"But, Tom, they might fire at us from behind the rocks," said Marks. "That would be ugly, you know." "Ugh!" said Tom, with a sneer.
"We want a party of runaway niggers," said Tom Loker. "One George Harris, and Eliza Harris, and their son, and Jim Selden, and an old woman. We've got the officers, here, and a warrant to take 'em; and we're going to have 'em, too.
"I am George Harris. A Mr. Harris, of Kentucky, did call me his property. But now I'm a free man, standing on God's free soil; and my wife and my child I claim as mine.
"I know very well that you've got the law on your side, and the power," said George, bitterly. "You mean to take my wife to sell in New Orleans, and put my boy like a calf in a trader's pen, and send Jim's old mother to the brute that whipped and abused her before, because he couldn't abuse her son. You want to send Jim and me back to be whipped and tortured, and ground down under the heels of them that you call masters; and your laws will bear you out in it,-- more shame for you and them!
"Now, Jim," said George, "look that your pistols are all right, and watch that pass with me. The first man that shows himself I fire at; you take the second, and so on. It won't do, you know, to waste two shots on one."
"But what if you don't hit?" "I shall hit," said George, coolly. "Good! now, there's stuff in that fellow," muttered Phineas, between his teeth.
"Was ever such a sneaking varmint?" said one of the men; "to come on his business, and he clear out and leave us this yer way!" "Well, we must pick up that feller," said another. "Cuss me if I much care whether he is dead or alive."
My poor old mother always told me 't would be so." "La sakes! jist hear the poor crittur. He's got a mammy, now," said the old negress.
"I'm glad to hear you say so," said George. "It would always be a heavy thought to me, if I'd caused his death, even in a just cause."
"Yes," said Phineas, "killing is an ugly operation, any way they'll fix it,--man or beast. I've seen a buck that was shot down and a dying, look that way on a feller with his eye, that it reely most made a feller feel wicked for killing on him; and human creatures is a more serious consideration yet, bein', as thy wife says, that the judgment comes to 'em after death. So I don't know as our people's notions on these matters is too strict; and, considerin' how I was raised, I fell in with them pretty considerably."
"What shall you do with this poor fellow?" said George. "O, carry him along to Amariah's. There's old Grandmam Stephens there,-- Dorcas, they call her,--she's most an amazin' nurse.
In the web, over the last five or 10 years, we've kind of established a new type of partner and those are traffic partners In a traffic partner, we have long-term agreements with other companies that deliver predictable levels of customers to our website. How do we do that?
Everything in human experience, and really human history or human civilizations experience, is that everything seems to fall to the earth, that if you have water particles, they don't just float up. If they are small enough they are being held up by the wind and all that, but if they are large enough, they will fall.
That you don't have people that are able to just float around, they will fall.
You don't have taxi cabs that float around, they'll fall.
Not only will the water fall, it will hit the ground, it will puddle up, and if there is a gutter it will fall into the gutter.
It is just trying to get lower and lower and lower.
If i were to drop a bunch of needles they would just fall.
If i had a needle at rest here it doesn't just automatically for no reason jump and fly upwards and start to float.
And so it is just a thing that is fundamental to everything that we have ever ever experienced.
And so, for most of human history or human civilization, we just accepted it as a given.
We thought, "well look it's just obvious, everything should just fall down, that's just the way the universe is. To think otherwise would just be crazy." And that's why this guy, this guy right over here, is one of the greatest geniuses of all time.
He did many more things than just the things I am going to describe in this video, and any one of those things would have earned him his place in history.
And this, as you may already know, is Isaac Newton.
Easily one of the top five minds in all of human history.
So a pretty fascinating dude.
And one of his big insights about this 'things falling down' problem is: Do they have to fall down? Is this just something we should assume about the universe?
What we now know is most startups fail from a lack of customers than from a failure of product development and that's really interesting even in Silicon Valley where we would probably take more technical risk per square inch or square foot than anywhere else in the world. We go out of business typically not because we didn't deliver a product. We go out of business, because we didn't find enough customers to pay us enough money.
"Oh, I have a great Rolodex, great set of contacts." But we really have no formal process for searching for what customers needs are, and in fact, we've just come up with one and that's going to be a key part of this course. This search for the business model.
So let’s take a look at our Jersey Square team as an example and see how they came up with their value proposition. Now, what’s interesting is if you remember value proposition describes not only the features but also the pains and gains that they see, that they’ve actually craved for the customer and that the goal is to figure out what the MVP is. And if we see the Jersey Square team, they actually did a pretty good job talking about pains and gains, a cheaper way to wear officially licensed sports jerseys to a game, to eliminate the risk of owning a player’s jersey who is going to be traded, or to provide an alternative to purchasing counterfeit jerseys.
So, while the goal in value prop is to figure out the MVP, yes, we’il see later the goal in customer segments is to figure out who and what the archetype of the customer is. So again you could start either with customer segments or you could start with a product and value prop itself, it really doesn’t matter. But in most teams if they are technology driven, they tend to start on value prop and most teams if they happen to be marketers or business people, happen to start with the customer segments.
Let's prove with the derivative of e to the x's, and I think that this is one of the most amazing things, depending on how you view it about either calculus or math or the universe. Well we're essentially going to prove-- I've already told you before that the derivative of e to the x is equal to e to the x, which is amazing. The slope at any point of that line is equal to the x value-- is equal to the function at that point, not the x value.
ln of x is equal to 1/x. The derivative of log base e of x is equal to 1/x.
Let me keep switching colors to keep it interesting. Let's take the derivative of ln of e to the x.
This is almost trivial. This is equal to the logarithm of a to the b is equal to b times the logarithm of a, so this is equal to the derivative of x ln of e.
And this is just saying e to what power is equal to e. Well, to the first power, right? So this just equals the derivative of x, which we have shown as equal to 1.
I think the school or the nation should take a national holiday or something, and people should just ponder this, because it really is fascinating. But then actually this will lead us to I would say even more dramatic results in the not too far off future. Anyway, I'll see in the next video.
I thought I would think about changing your perspective on the world a bit, and showing you some of the designs that we have in nature.
And so, I have my first slide to talk about the dawning of the universe and what I call the cosmic scene investigation, that is, looking at the relics of creation and inferring what happened at the beginning, and then following it up and trying to understand it. And so one of the questions that I asked you is, when you look around, what do you see? Well, you see this space that's created by designers and by the work of people, but what you actually see is a lot of material that was already here, being reshaped in a certain form.
And you'll see, first, the structure of the survey, and then you'll start seeing the structure of the galaxies that we see out there.
So again, you can see the extension of this Great Wall of galaxies showing up here. But you can see the voids, you can see the complicated structure, and you say, well, how did this happen? Suppose you're the cosmic designer.
Now we're going to zoom back out, and you can see this structure that, when we get very far out, looks very regular, but it's made up of a lot of irregular variations. So they're simple building blocks. There's a very simple fluid to begin with.
So this is what we started with 15 years ago, with the Cosmic Background Explorer -- made the map on the upper right, which basically showed us that there were large-scale fluctuations, and actually fluctuations on several scales. You can kind of see that. Since then we've had WMAP, which just gives us higher angular resolution.
Thank you.

Solve for a and check your solution. And, we have a plus 5 is equal to 54. Now, all this is saying is that we have some number, some variable a, and if I add 5 to it, I will get 54.
And then, 54 minus 5 that is 49, and we're done. We have solved for a. a is equal to 49. And now we can check it.
49 plus, let me do that in that same shade of green, 49 + 5 is equal to 54, we're trying to check this, 49 + 5 is 54, and that indeed is equal to 54, so it all checks out.

Let's take a look at our Jersey Square team and because they understand their archetype is interested in both subscription and rental, let's see what they were thinking. And they said well, let's see one particular model could be an annual subscription, which is a strategy and here is the tactic at a $199 per year and we could give them authentic top of line jerseys and free shipping and send a jersey back and exchange for another.
What I want to do in this video is show you a way of subtracting numbers that is different than the regrouping technique. And this is closer to what I actually do in my head. And this might not be what you see in school, so be careful while you're looking at this.
It is not unusual in calculus textbooks to see something-- to see problems along the lines of, prove that the limit as x approaches-- I don't know, say, as x approaches 1. Let me think of an interesting function when x approaches 1. Let's see.
3x times x minus 1 over x minus 1. And you might say, hey Sal, why did you do this x minus 1 in the numerator and denominator? Well, I did that because obviously you can't have a 0 down here.
We already know that an angle is formed when two rays share a common endpoint. So, for example, let's say that this is one ray right over here, and then this is one another ray right over here, and then they would form an angle. And at this point right over here, their common endpoint is called the vertex of that angle.

Andrew Goldberg described a data structure that can be used to very rapidly compute shortest-path distances between nodes in a network. The way that it worked was each node of the network has a label. What a label is is a list of other nodes in a network that he called hubs along with the distance to that hub.
I love the Internet. It's true. Think about everything it has brought us.

All right, to introduce this concept, it's going to help to have another definition that I haven't given you yet. So here's a graph, we have been talking about things like shortest paths. So let's look at a path from a to g.
Write the prime factorization of 75. Write your answer using exponential notation. So we have a couple of interesting things here.
3 is another prime number.
Now, 4 is not prime, because this is divisible by 1, 2 and 4. We could keep going.
5, well, 5 is only divisible by 1 and 5, so 5 is prime.
6 is not prime, because it's divisible by 2 and 3. I think you get the general idea. You move to 7, 7 is prime.
8 is not prime.
9 you might be tempted to say is prime, but remember, it's also divisible by 3, so 9 is not prime. Prime is not the same thing as odd numbers. Then if you move to 10, 10 is also not prime, divisible by 2 and 5.
11, it's only divisible by 1 and 11, so 11 is then a prime number. And we could keep going on like this. People have written computer programs looking for the highest prime and all of that.
Well, 75 is an odd number, or the number in the ones place, this 5, is an odd number.
5 is not divisible by 2, so 2 will not go into 75. So then we could try 3. Does 3 go into 75?
Well, 7 plus 5 is 12.
12 is divisible by 3, so 3 will go into it. So 75 is 3 times something else. And if you've ever dealt with change, you know that if you have three quarters, you have 75 cents, or if you have 3 times 25, you have 75.
7 is not divisible by 3, so 25 will not be divisible by 3. So we keep moving up: 5.
25 is 5 times 5.
3 times 25, 25 is 5 times 5. So this is a prime factorization, but they want us to write our answer using exponential notation. So that just means, if we have repeated primes, we can write those as an exponent.
So what is 5 times 5?
5 times 5 is 5 multiplied by itself two times. This is the same thing as 5 to the second power. So if we want to write our answer using exponential notation, we could say this is equal to 3 times 5 to the second power, which is the same thing as 5 times 5.
All right--so why is that--so it turns out that this little plastic ring thing, you can think of it as a graph where each of the little plastic connectors is actually an edge between nodes and the place that they intersect is a node. We've got a node here and a node here--they're connected. Node here and node here--they're connected, connected.
Welcome to the second presentation on functions. So let's take off where we left off before. I still apologize -- in retrospect that that whole Sal food example.
And let's say -- I'm going to make it really complicated -- well, actually I'm not going to make it any more complicated now. So let's try some problems. So let's give an example.
What is f of 5. Well, it's really pretty straightforward. We take this 5 and we replace it for x in the function f.
So f of 5 is equal to 5 plus 3 times g of 5, right? We just literally took this 5 and replace it everywhere where we see an x. If instead of a 5, I had like a dog here, it would be f of dog would equal dog plus 3 times g of dog.
So f of 5 equals 5 plus 3 times g of 5. But what does that equal? So the 5 stays the same, plus 3 times -- well what's g of 5?
And once again, that equals 6 plus -- well, this time g of 6 is, well, 6 is even, so 1. So g of 6 is equal to 1. So this equals 6 plus 3 times 1.
Now I'm going to give you a tough problem. What is h of g of x? No.
What is h of g of -- let's pick a number -- let's say 3? h of g of 3. Actually, we'll do examples in the future where we actually could leave the x there and we'll solve for it. But let's say this particular example, what is h of g of 3?
3 minus 3, right? So this g of 3 is equal to 6 plus f of what?
3 minus 3 is 0. Now we have to figure out f of 0 is. We have a definition here for f, so we just figure it out. f of 0 is equal to -- well, you replace the 0 here.
So g of 3 is equal to 7, right? Now we know what g of 3 is equal to. We can substitute that back here.
And h of 7 is just equal to 5 times 7 equals 35. So I think you're probably a little confused here, and I would have been if I was in your shoes. But the important thing is when you first see this problem you're like what can I tackle first? h of g of 3, it seems very confusing.
Well, g of 3, can I tackle that? Sure. I have a definition of what the function g does when it's given an x, or in this case, was given a 3.
You can sit and think a little bit about what we just did while I erase.
So let's do another problem. What is f of h of 10?
Well, first we want to figure out what h of 10 is, right? Well, we could do it in a different way as we'll see later. But we can figure out what h of 10 is pretty easily.
And then f of 50 is, I think pretty straightforward at this point. You just take that 50 and replace it back here. Well, it's 50 squared plus 1.
That equals 2,501. What is g of h of 1? Well, we take h of 1, h of 1 is 5, so this is equal to g of 5.
Well, 2 squared plus 1 is 5, right? f of 2 is 5
-- 2 squared plus 1. So that equals 10 plus 5 which equals 15. If you're still confused, don't worry.
We need to divide 0.25 into 1.03075. Now the first thing you want to do when your divisor, the number that you're dividing into the other number, is a decimal, is to multiply it by 10 enough times so that it becomes a whole number so you can shift the decimal to the right. So every time you multiply something by 10, you're shifting the decimal over to the right once.
25 does not go into 10.
25 does go into 103. We know that 4 times 25 is 100, so 25 goes into 100 four times.
4 times 5 is 20.
4 times 2 is 8, plus 2 is 100. We knew that. Four quarters is $1.00.
103 minus 100 is going to be 3, and now we can bring down this 0. So we bring down that 0 there.
25 goes into 30 one time. And if we want, we could immediately put this decimal here. We don't have to wait until the end of the problem.
1 times 25 is 25, and then we can subtract.
30 minus 25, well, that's just 5. I mean, we can do all this borrowing business, or regrouping. This can become a 10.
10 minus 5 is 5.
2 minus 2 is nothing. But anyway, 30 minus 25 is 5. Now we can bring down this 7.
25 goes into 57 two times, right?
25 times 2 is 50.
25 goes into 57 two times.
2 times 25 is 50. And now we subtract again.
57 minus 50 is 7. And now we're almost done. We bring down that 5 right over there.
3 times 25 is 75.
3 times 5 is 15.
Regroup the 1. We can ignore that. That was from before.
3 times 2 is 6, plus 1 is 7. So you can see that. And then we subtract, and then we have no remainder.
Welcome to the presentation on derivatives. I think you're going to find that this is when math starts to become a lot more fun than it was just a few topics ago. Well let's get started with our derivatives.
And another way of saying that is delta-- it's that triangle-- delta y divided by delta x. Very straightforward. Now what happens, though, if we're not dealing with a straight line?
Now let's say, instead of just a regular line like this, this follows the standard y equals mx plus b. Let's just say I had the curve y equals x squared. Let me draw it in a different color.
Let's call this point a. At this point, x equals a. And of course this is f of a.
So what we could try to do is, we could try to find the slope of a secant line. A line between-- we take another point, say, somewhat close, to this point on the graph, let's say here, and if we could figure out the slope of this line, it would be a bit of an approximation of the slope of the curve exactly at this point.
Something like that.
Secant line looks something like that. And let's say that this point right here is a plus h, where this distance is just h, this is a plus h, we're just going h away from a, and then this point right here is f of a plus h.
So this would be an approximation for what the slope is at this point. And the closer that h gets, the closer this point gets to this point, the better our approximation is going to be, all the way to the point that if we could actually get the slope where h equals 0, that would actually be the slope, the instantaneous slope, at that point in the curve. But how can we figure out what the slope is when h equals 0?
So right now, we're saying that the slope between these two points, it would be the change in y, so what's the change in y? It's this, so that this point right here is-- the x coordinate is-- my thing just keeps messing up-- the x coordinate is a plus h, and the y coordinate is f of a plus h.
And this point right here, the coordinate is a and f of a. So if we just use the standard slope formula, like before, we would say change in y over change in x. Well, what's the change in y?
Two weeks ago I was in my studio in Paris, and the phone rang and I heard,
"Hey, JR, you won the TED Prize 2011. You have to make a wish to save the world." I was lost.
(Laughter) Except maybe French people. Whatever.
"Look, Amy, tell the TED guys I just won't show up. I can't do anything to save the world." She said, "Hey, JR, your wish is not to save the world, but to change the world."
(Laughter)
"That's cool." I mean, technology, politics, business do change the world -- not always in a good way, but they do. What about art?
That's how, at 17 years old, I started pasting them. And I did my first "expo de rue," which means sidewalk gallery.
I mean, the city's the best gallery I could imagine. I would never have to make a book and then present it to a gallery and let them decide if my work was nice enough to show it to people. I would control it directly with the public in the streets.
(Laughter) November 2005: the streets are burning. A large wave of riots had broken into the first projects of Paris.
And then I pasted huge posters everywhere in the bourgeois area of Paris with the name, age, even building number of these guys.
A year later, the exhibition was displayed in front of the city hall of Paris. And we go from thug images, who've been stolen and distorted by the media, who's now proudly taking over his own image. That's where I realized the power of paper and glue.
So could art change the world? A year later, I was listening to all the noise about the Middle East conflict.
"How big will my photo be?" "It will be as big as your house." When we did the wall, we did the Palestinian side.
"Calm down. No wait. I'm going to find you a solution."
(Laughter) We did Face 2 Face with only six friends, two ladders, two brushes, a rented car, a camera and 20,000 square feet of paper. We had all sorts of help from all walks of life.
Okay, for example, that's Palestine. We're in Ramallah right now. We're pasting portraits -- so both portraits in the streets in a crowded market.
"What are you doing here?" "Oh, we're actually doing an art project and we are pasting an Israeli and a Palestinian doing the same job. And those ones are actually two taxi-drivers."
"So can you tell me who is who?" And most of them couldn't say.
(Applause) We even pasted on Israeli military towers, and nothing happened. When you paste an image, it's just paper and glue.
In the Middle East, I experienced my work in places without [many] museums. So the reactions in the street were kind of interesting. So I decided to go further in this direction and go in places where there were zero museums.
When you go in these developing societies, women are the pillars of their community, but the men are still the ones holding the streets. So we were inspired to create a project where men will pay tribute to women by posting their photos. I called that project Women Are Heroes.
(Applause) What was interesting is that the media couldn't get in. I mean, you should see that.
(Laughter) Or they tell you, "Are these people all dead?" Some who understood the project would explain it to others.
"You know, you've been here for a few hours trying to understand, discussing with your fellows. During that time, you haven't thought about what you're going to eat tomorrow. This is art."
(Laughter) When the roofs were covered, a woman said as a joke,
"Now God can see me." When you look at Kibera now, they look back.
Okay, India. Before I start that, just so you know, each time we go to a place, we don't have authorization, so we set up like commandos -- we're a group of friends who arrive there, and we try to paste on the walls. But there are places where you just can't paste on a wall.
"Hey, what are you up to?" "Oh, you know, we're just doing art." "Art?" Of course, they were confused.
(Applause) Thank you. So we didn't get caught this time.
Each project -- that's a film from Women Are Heroes.
(Music) Okay. For each project we do a film.
And the photos kept traveling even without us.
(Laughter) (Applause) Hopefully, you'll see the film, and you'll understand the scope of the project and what the people felt when they saw those photos. Because that's a big part of it.
Because of course, when we left, the people who were just at the edge of the project said, "Hey, what about my roof?" So we decided to come the year after and keep doing the project. A really important point for me is that I don't use any brand or corporate sponsors.
(Applause) And that is for me one of the more important things in the work. I think, today, as important as the result is the way you do things.
"Look, you're going to have to tear it down. Because this can be taken for advertising, and because of the law, it has to be taken down." But tell me, advertising for what?
(Applause) This image of three men wearing gas masks was taken in Chernobyl originally, and I pasted it in Southern Italy, where the mafia sometimes bury the garbage under the ground.
In some ways, art can change the world. Art is not supposed to change the world, to change practical things, but to change perceptions. Art can change the way we see the world.
(mock drum roll) (Laughter) I wish for you to stand up for what you care about by participating in a global art project, and together we'll turn the world inside out. And this starts right now.
(Applause) Thank you.
(Applause)
Welcome back.
So let's continue where we left off.
So we had this intuition that i must have something to do with these sign changes, right?
The pattern of the sign changes of i are very similar to the pattern of the sign changes in the Maclaurin representation of cosine of x plus sine of x.
And then we also saw that the i's, whether they're positive i's or negative i's, correspond to the sine terms.
So let's do a little experiment.
And it's not an experiment because I know where this
leads to, but it could have been an experiment.
Well, raising anything to the i power really isn't defined.
I mean, i, itself, was created by a definition.
We said, "i squared is equal to negative 1 by definition." So i is a bit of a definition.
So if we haven't defined what something to the i power is yet, we really don't know what to do with it.
But let's just say that we can treat i just like any other number.
And we do know what happens with i when you put it into a polynomial.
That's one thing we do know.
In fact, that's one of the reasons why i was defined in first place was so that people could take roots of all polynomials, even ones that didn't have real roots.
So what happens if we take e to the i x?
Well, I don't know what that is but we know we could put that into the Maclaurin representation of e to the x and actually, since you're taking my leap of faith, that that is equal to e of x and all of its derivatives are equal to e to the x's derivatives at x equals 0, it's not that hard to imagine.
And actually, you could plot the graph of this and you'll see that they're identical.
Now, if you've been around software engineering long enough, you'll realize that most of the technology that makes up the web isn't really new or cutting edge. It's actually old technologies with new, sometimes worse names. Now, I think
Atlases and spreadsheets are a perfect point of this. So a spreadsheets in the
HTML5 world actually describes that what we use an Atlas. But this is very, very wrong. See back in the 2D days of making games.
So a couple of years ago I started a program to try to get the rockstar tech and design people to take a year off and work in the one environment that represents pretty much everything they're supposed to hate; we have them work in government. The program is called Code for America, and it's a little bit like a Peace Corps for geeks. We select a few fellows every year and we have them work with city governments.
"What we do together that we can't do alone." Now a lot of people have given up on government. And if you're one of those people,
"I walked over to this location, found the trashcan behind the house. Opossum? Check.
Welcome to the presentation on adding and subtracting negative numbers. So let's get started. So what is a negative number, first of all?
So let's do the problem 5-12
But let me draw a line, 5-12 So let me start with -10, -9, -8-- I think I'm going to run out of space-- -7, -6, -5
Let's do another one. So what happens when you get let's say, 2 minus -3?
Let's do a bunch of these. I think the more you do, the more practice you have, and the modules explain it pretty well. Probably better than I do.
If this is 0, this is 5 and now we're going to go to left 8, then we end up at -3 You could do that for all of these. That actually might be a good exercise.
I am an author. That is one of my identites but until about six months back I carried another identity - that of a banker.
"Long? Yeah, okay. But why strange?"
But before my first book which was released last year, 'The Immortals of Meluha', before that I had written absolutely no fiction ever in my life. Not even a short story in school - absolutely nothing, except for some really terrible poetry, which nobody really liked and that was in my college days. The only one who liked my poetry was my girlfriend and that was one of the reasons that I actually married her.
"Hire a Driver." That was probably [...] This was 6 years ago.
"Dude, it looks like you actually want to alienate every single reader segment." So I said, "Okay, how?" They said, "Look, you're writing on religious philosophies, which the youth aren't really interested in, you've got your own take on religion, you are taking some liberties with the conventional view on religion -- which means the older religious people will not like it and you're insisting on writing in modern easy English, which means the literary will not like it.
"If you find yourself in a place where your work itself gives you pleasure, where failure doesn't fill your heart with sadness and success doesn't fill your mind with pride. Then you know that you're working in consonance with your soul's purpose." I am in that wonderful place.
I'm now going to do a bunch more examples using the chain rule. So let's see. Once again.
OK. So let's say I had, let me see if I can write it a little bit thinner. If I had f of x, I don't know if you can see that, I'm going to do it a little fatter. f of x is equal to, I want to make it a little bit more complicated this time.
Because the derivative of x to the fifth is 5x to the fourth, right? But instead of an x, we have this whole expression, 5x to the third minus 7x. So we'll write that.
How many ounces are in 6 pounds? So we have 6 pounds and we need to convert them to ounces. And if you don't know it already, you'll know it now, that there are 16 ounces per pound.
The answer is simple math. And after two days, you have activated 20 customers. After seven days you'll activate 70.
Why is having a customer archetype important?
Have you ever had the feeling that there's something bigger out there? Something you can't see? Well there is.
Welcome to programming languages. We will just do a few elementary concepts and broad classifications of programming languages without going into too much detail. This is the first lecture so let us just look at the notion of a program or a programming
language. You are all familiar with the notion of a machine or a computer and it is what
one would call a bare machine. It just has a piece of hardware which is usually in binary.
It can be thought of as a whole lot of switches connected with complicated circuitry. The memory, the arithmetic unit etc. consists of switches activated one way or the other
and it is going to be a big problem operating those millions and millions of switches. What you have in a bare machine is a language consisting of binary strings.
Binary string in what is known as the Von Neumann architecture is called the stored
program concept. Both data and instructions have the same format and everything is a binary
string depending upon how you look at it; it is either a data item or an instruction to execute a command. The Von Neumann concept means that programming such a machine basically
helps you to interpret certain sequences of bits either as data or as instructions to
manipulate some registers or store into the memory, perform some arithmetic or logical
operation etc. In general even that language what we might call the machine language can be called a programming language. Let us take a very general view.
of algorithms and data structures presumably you are able to perform your manipulations. The first point about a bare machine is that if you are going to use the machine language itself then there is really no fundamental difference between the algorithm and the data, which means a sequence of instructions could just as well be regarded as a sequence of data items provided they have some circuitry that could also be executed as an algorithm.
In principle, you could execute even a sequence of data items as instructions by interpreting it suitably. The first distinction we would like to draw is between what constitutes the data item and what constitutes an instruction.
Let us take a much more high level view. We are no longer in the fifties when the early machines came in and you had to program in machine language or assembly language. So, we will just look upon a programming language as a notation for describing algorithms and data.
sentence of a programming language. A program is not necessarily an algorithm simply because you might have a well formed sentence which is not very meaningful. For example; the program could be a non terminating program in which case it is no longer an algorithm.
It is therefore important to realize that an algorithm is a very abstract object that
does not have any concrete form.
Only what is put down as a program is concrete. The only concrete object that you can have is a program. The notion of an algorithm itself is an abstract entity which requires a concrete representation in the form of a program and if a program is a sentence of the programming
as a specification of a computation. This means we have some notion of what constitutes
a primitive step of the computation and the program gives you a finite representation of possibly an infinite sequence of steps in a computation process.
The emphasis in all these cases is in the nature of a finitary specification. A program should be a finite object by itself. A programming language itself is not a finite object because there are an infinite number of programs that are possible but each program itself is a finite object because it is just a sentence of the programming language.
In all these cases, we should emphasize the fact that this notation is important because our notation is to give you a finitary specification of possibly infinite objects.
We might emphasize that this is actually a finitary specification and these programs themselves as concrete
objects are finitary but their effects could be infinitary. The moment you are trying to
represent any infinitary object in a finite manner you require it to be machine understandable and you also require certain rules. Let us look at this process of essentially
giving a finitary representation to what you might consider infinitary objects.
What kinds of infinitary objects are we normally concerned with? In the most general case an algorithm is what you want to represent in a program. An algorithm in the most general case is a function from some domain to some co domain.
be finitary because the domain could be infinite and the co domain could be infinite. We might think of an algorithm in general as computing either a function or a method for computing
some mathematical function or relation. These functions and relations could be infinitary.
We are looking at infinitary objects as functions. Basically mathematical functions relations can also be considered functions. All relations could be considered functions.
However, if you look at mathematics itself it has a fairly rigorous notation. You could
think of mathematics itself as a sort of programming language except that it has one important drawback. The drawback is that it does not specify the primitive computations that are possible within the mathematical language. Normally when you are talking about an algorithm to compute some function, you have implicitly
defined a set of primitive functions or primitive computation steps in terms of which you are going to express this algorithm. One obvious case in which a lot of mathematics does not fit into the general framework of a programming language is the representation of infinite sets. If you look at them, the standard point in
school is to say that you can either represent a set in a roaster form or in set builder form. Roaster form just means enumerating a list of elements and a set builder form essentially means giving a predicate which the elements of the set should satisfy.
The main difference between the roaster form and the set builder form, also called a definition by abstraction comes up for infinite sets. Supposing in the case of infinite sets you want to specify
the set of even numbers so you open braces, you write 0 or if you do not include 0 then you write 2, 4, 6... That is where the inadequacy of mathematical
notation comes because you are not interested really in any underlying computation process.
As far as mathematics is concerned a large part of it is just that the existence is more important than a computational method. Whereas the set builder notation or the definition
by abstraction gives you a finitary specification so that you can represent the set of even numbers through a notation which consists of braces that consists of a bound variable,
and a predicate in terms of the bound variable. A typical definition of even numbers would look something like this.
Take 2x where x belongs to the natural numbers. If you look at x, x is like a locally declared
variable. In fact this is a sort of declaration of x and this 2x is a property that the element
of this set should satisfy. Here is a case of our finitary specification as opposed to this infinitary specification.
In fact this is a finitary specification in more ways than one. Firstly, this represents a logical predicate expressed in first order logic in a finite sentence of the first order logic.
specification of essentially an infinitary object, the even numbers. Whereas this is really open to many. This is really ambiguous in the sense that it is not at all clear from this enumeration what should be the next one.
would be eight but we cannot at all be sure that the next number should be eight. There might be other patterns. It might satisfy other predicates whereas this is what one might call an accurate succinct finitary representation using just the language of first order logic built up on a single
binary predicate on sets, which is the binary predicate this belongs to.
A lot of what we are going to do is also going to be related to the language of logic in some ways. You will see the analogies between programming languages and logic as we go along. The main motivations of logic are really of a slightly more abstract nature but programming
does not allow you the freedom to write these dots and there is no such thing. You have a method of construction of predicates which is always finitary.
You have rules of inferential logic which are always finitary or they might be infinitary
like if you have axiom schemas, or rules like modes ponens etc. They are finitary representations again of infinitary objects.
Further in a logical language with axioms and rules of
inference it is implicitly understood that those axioms and rules of inference are such
that there exists an algorithm which when given any instance of the hypothesis of these
rules, should be able to tell you whether the conclusion of the rule is a valid inference.
Let us take a simple logical rule like modes ponens.
You have a predicate X, you have a predicate X -> Y and you have Y. This rule actually
specifies a three tube pair of this form where X and Y belong to (let us say) the language
of first order logic, which we may call L1 as opposed to proposition logic which we may write L NAUGHT. You take two sentences of first order logic and if they have this pattern
then call one sentence X and the other sentence has the pattern X conditional Y then you are able to infer Y and you cannot have all rules of inferencing logic. They are finitary.
There are also finitary specifications and something that is absolutely essential is that it is decidable by an algorithm whether a certain step in the proof of a logical statement
was derived by an application of a rule of inference on some preceding steps.
If you claim that you have some predicates of the form A -> B ->NAUGHT C
and then you derive from these premises if you were to claim that by the use of modus ponens you can infer NAUGHT C then there has to be an algorithm which when given these
two as inputs will be able to tell you whether this is an instance of an application in these two definitions. In this case the algorithm should actually tell you that it is not an application in this rule of inference. It should be able to give you both yes and no answers in finite time.
languages that we will study will have a lot of their motivations actually derived from A large part of logic was actually concerned with the notion of how much of mathematics is actually doable by a machine and what kinds of theorems in mathematics can be actually
proved by algorithms by a machine whose basic primitive operations are that they are able
to do pattern matching and substitution. This is an instance of doing pattern matching and substitution. An inference rule is really an infinite object.
A theorem itself is a sentence of logical language and is a finite object representing possibly an infinite number of instances.
Everything that is infinitary should have a finite representation. There are of course infinitary objects which will have no finite representations. They are clearly not going to be part of our computational process.
process period. We are interested in those kinds of infinitary objects which somehow have finitary representations. It can be infinite sets represented as predicates like unary,
binary, and ternary but some finitary sets with a finitary representation. We are interested in infinitary computational processes which have finitary representations. We are interested in programming languages which allow for finitary representation of inherently infinitary objects.
Let us go ahead. This much of philosophy is perhaps sufficient for the moment but it is important to realize that right from nineteen hundred when the mathematician David Hilbert posed this problem to the congress in mathematics the main emphasis of logicians has been to try; to define the notion of an
algorithm, to define the notion of the computational process, to be able to exactly define what is possible by a computational process and what is not possible by a computational process. Everything that is possible by a computational process should have a finite representation and anything that is infinitary is not part of the computational process with some restrictions.
If we just come down from logic a bit then we can look at a logical language itself as
a mathematical object for example; there exists only a finite number of rules for generating an infinite number of sentences of that language. Let us take a language like first order logic. We have only a finite set of formation rules,
which allow you to generate an infinite number of logical sentences. A finitary nature of
the rules also gives you an algorithm to check whether a given string of symbols is a syntactically
valid sentence of the logical language. An important element of that logical language is that the generation process should be finitary. There should be only a finite set of rules and there should be an algorithm which can clearly tell you whether a given sentence is a well formed sentence of the language.
If you look at propositional logic, it does not allow you to specify infinitary objects
that we require for applying propositional logic to some area of mathematics like number theory. It does not allow you to specify infinite sets or certain properties of infinite sets easily. Very often, an extension of proportional
theory I mean axiomatic set theory in the sense that we do not assume numbers or any predefined set of objects. The only notion is the notion of a set. You generate all sets, numbers and everything from the notion of an empty set and a single binary predicate called belong stood.
which is platonic in nature in the sense that the notion of a computation itself is not an important element of the formal discipline of mathematics. Then you have logic which actually gives you a loose notion of what is possible by a machine and what is not possible and allows you to specify infinitary objects in some finitary ways.
processes that you are allowed to use. A programming language also has to satisfy all the constraints
of a logical language and in addition it should be consistent with what might be called the
primitive computational processes. For example; one primitive computational process that you must all have studied in school is that of ruler and compass constructions. There
are only two primitive computational steps. We are able to draw lines with the ruler,
mark off segments. One impossible computation in this case is an algorithm using only this primitive concept to trisect an arbitrary angle.
For example; you are not allowed to use protractors etc. and you are not allowed to measure the angle. You can only prove that an angle is of a certain measure if you draw a line perpendicular to another line; with a construction proof it shows that it is perpendicular and then you bisect that. You can then claim that the bisected angle is let us say, forty five degrees.
in a programming language. It is not machine readable. It is meant to be human readable so you write it in a lose fashion but essentially you use only those computations which are possible within the domain of Euclidean geometry which means you are not allowed to measure out angles yourself.
Our programming language has in grained in it a normal computational process which we
associate with a digital computer. It is not the last word because you could have other computational process such as the ruler and compass constructions. You could have analog computers etc.
We could look at even the machine language as a programming language but we are not really
interested in machine language because it is a very simple sort of a language. It is very difficult to get any program right but the language itself is a very simple language and probably that is why it makes it so difficult to program and what we are interested in primarily are what are known as high level languages where the primitives of the computation or
what you might say is the machine that is made available. Once we have implemented a
language on a machine you could think of that as a machine of that language.
Supposing when we are doing PASCAL programming we are not really worried about the underlying
machine language, the underlying architecture or about anything for that matter. As far as we are concerned what we have is a PASCAL machine. There is a level of abstraction at
which PASCAL is the hardware machine language or it is just some software language. As far
as we are concerned it is a PASCAL machine. It is important to realize that we can actually take some bear machine and cover it up with layers and layers of software and think of just one abstract machine which gives us certain capabilities.
It allows various kinds of abstraction mechanisms, procedures, functions and it allows you to
express differently from what the bare machine would have given you. Let us look at why we
should study programming languages because all the time we are looking at the construction of some virtual machine and facilities that the machine gives us which we are not really
We are interested in various kinds of features that are there.
If you have a PASCAL machine its architecture is really the features of PASCAL. If you have a LlSP machine its architecture is really the features of LlSP.
Our study of programming languages is mainly to understand why certain features have been
included in the programming language. You want to understand for example how best those features could be used. If you want to understand how that language is implemented
presumably you would be able to learn new languages easily. You could design a new language which is more important and perhaps you would also be able to understand the underlying implementations. May be you would be able to incorporate new features in a programming
languages. An imperative language means that it uses the notion of the command. It uses
the notion of a state to change a state. So the commands change states. That is what an imperative language would do.
a bit more in detail later. A broad classification of languages is just in terms of high level languages imperative, functional, logic etc.
instruction multiple data and you execute instructions in parallel and there are implicit methods to implement them in a parallel fashion. You have what are known as distributed languages. In the case of a parallel language you assume that there are so many processors which will execute the same instructions in a synchronous
lock step fashion. Most of the vector processors actually have sequential languages vectorized or made parallel like in the case FORTRAN 90, VECTOR PROCESSlNG FORTRAN etc.
task. Then in both parallel and distributed languages the
notion of a process of a computational process into which a program is split is inherently or intimately related to the computational power to the number of units of computation. That number of units is of the CPUs that you have. The notion of a process and a processor are really the same.
Let us quickly go through some of these languages. If you were to take the history of programming
languages, you would find that there is a certain chronological dependence. The first high level languages so to speak were FORTRAN which is mainly meant for scientific computation and then COBOL which is meant for business. It was more verbose.
amount of data and do very low processing. They were IO bound programs whereas FORTRAN was meant for minimal IO and maximum computation. These languages gave rise to one important
class of languages called the ALGOL like languages which came from the 'ALGOL 60' Report.
FORTRAN also had its offshoots in basic. Then there were these ALGOL like languages. Among
the ALGOL like languages you have PASCAL, PL1 and Simula etc. PL1 was an attempt at a unified language for both scientific and business commercial processing and from PASCAL you get extra features like Modula and Ada.
From Simula you have got these object oriented languages starting from Smalltalk-80. All these and somewhere in a parallel stream you have BCPL and C. Actually BCPL was a transformation of a language called B which itself was a transformation of a language called A. The programming language 'C' was derived from
buzz word. You had C++. That is briefly the pedigree of languages
that we have covered. We also have functional languages. Let us let us look at functional languages.
Apart from these imperative languages you had basically the first functional language which was LlSP from which we derived various versions MacLisp, Scheme Common Lisp. MacLisp and Common Lisp are really impure versions of LlSP. When we understand functionality we will come to what we mean by impure versions but many of you have probably studied Scheme.
There was also a language designed in the 60s called the SNOBOL which was meant for string processing. It allowed efficient pattern matching constructs to be programmed and these have actually yielded
along with the emphasis on tied checking to a language called ML. It came up in the 80s and all these languages like LlSP and ML were inspired by what is known as Lambda (位) calculus which we will study. It is the basis of all functional languages.
Just to recap, trademark protects branding and marks. It gives you the right to prevent others from using confusingly similar marks and logos. It lasts as long as you use the mark.
We humans have known for thousands of years, just looking at our environment around us, that there're different substances. These different substances...tend to have different properties. Not only do they have different properties; one might reflects light in a certain way, or not reflect light.
Another key component of understanding customers is understanding customer gains, which is a fancy way for saying what are the benefits that customers expect, or desires, so besides the jobs they want to get done what do they want to gain by using your product or service? Let's take a look. Some of the gains could be what would make them happy?
Alright, so the skeleton of this code is pretty much what you've already done before, but we're going to introduce a few other things here. First of all, we set this caller variable to be the caller of xhrGett. Now, this is a special thing in Javascript and what it does is, whoever ends up calling xhrGet, will be set as this xhrGet.caller parameter, and you can grab that as necessary.
Another graph type worth mentioning is a tree graph. A tree graph has two properties. The first property is that the graph must be connected, and the second property is that the graph doesn't have any cycles or loops.
This story is about taking imagination seriously. Fourteen years ago, I first encountered this ordinary material, fishnet, used the same way for centuries.
I want to create these oases of sculpture in spaces of cities around the world. I'm going to share two directions that are new in my work. Historic Philadelphia City Hall: its plaza, I felt, needed a material for sculpture that was lighter than netting.
Next challenge, the Biennial of the Americas in Denver asked, could I represent the 35 nations of the Western hemisphere and their interconnectedness in a sculpture? (Laughter) I didn't know where to begin, but I said yes.
If you take a look at our JSON file, this is where the layer data exists to describe what we want to draw. First, we need to loop through each layer and then for each layer loop through the tile IDs contained in the data of each layer.
If the given ID is not zero, then we go ahead and grab the packet information by calling the getTilePacket function, passing in the tile ID that we have.
Hi and welcome back to unit4 of CS215. We call this unit putting things in order or who is your 17th best friend. So, by now, you might not be surprised that I actually have a magic trick worked out that is, actually, in this case relevant to the topic at hand.
Well, hi and welcome back. We're now starting Unit 5. The topic of unit 5 is weighted graphs.
Every film is unique, but this film begins in a very mysterious way.
Thousands of dollars appeared in my bank account with no strings attached, no demands or conditions. Weeks later a letter explained that someone I'd never met would like me to visit a teacher: Bhagwan Shree Rajneesh and his spiritual community in Poona, India; and if I chose to go, I might also take a camera and some film.
And I was told that the money came from someone who lived very simply and yet it sent me all that they have. No contract could have been more compelling.
But, why me?
I wondered what this Bhagwan had to teach?
I knew about the famous master teachers of history but this Bhagwan was alive, my contemporary.
What is the power of such a teacher? A person whose life transforms other people's lives.
I wasn't a religious seeker. I pursued accomplishment, and love, pleasures of the mind and body. And like most people, I had experienced brief moments when I felt especially alive, in tune with everything.
and with that feeling came a sense of being a part of everything, being absolutely whole. I valued those times. These were the spiritual moments in my life.
I wondered, were the great teachers people who never came back from those peak moments?, the reason to share with others. I had my usual doubts, but I wanted to see for myself, just who is this Bhagwan Rajneesh and what's going on over the India.
This is a meditation. First heavy breathing and then crazy screaming, now this jumping and chanting. It's called "Chaotic Meditation".
Bhagwan is known as an enlightened teacher. He has over hundred books in print but he doesn't write them, they're just transcribed form his daily discourses. Every morning he speaks for ninety minutes.
Religion is a sort of intoxication. This has to be understood because without a deep intoxication, your life will never have any meaning. It will remain a superficial prose and will never become a poetry.
For Bhagwan what life is can't be figured out. The endless thoughts and patterns of the mind may be what's in the way. Shaking and dancing can silence the mind.
"I remember: Once Alexander the Great asked Diogenes, You are so learned, you know so much.
But the more I tried to catch hold of it, the more it became elusive. The more I thought about it, the farther away it was,
and the only thing I can say to you, is that those who think they know God, they know not."
"God can be known only when you are not...
(when you are not, (when you are not... when you are not)
God can be known only when you are not... when your ego is lost."
I guess I was raised with a strong ego, to have pride of my accomplishments, to respect the victories of great men, to believe that human beings with superior minds and ego had conquered nature. But these Indians showed me a more gentle, humble, respect for nature. Anointing cows looks peculiar to me, but this gesture celebrates the nobility of all life.
Bhagwan's mother and father arrived and joined in a many Indian ceremonies.
Everything was so different from home. But what an opportunity to travel beyond my usual attitudes and judgements, to just be here, with fresh eyes!
In the last presentation, I hopefully gave you a little bit of an intuition of what a derivative is. It's really just a way to find the slope at a given point along the curve. Now we'll actually apply it to some functions.
What is the slope at x is equal to-- let's say at x equals 3. What is the slope of x? Let's draw out what I'm asking.
So we want to say what is the slope when x is equal to 3.
This is x equals 3. And of course when x equals 3, f of x is equal to 9.
So what we do is we take a point, maybe a little bit further along the curve. Let's say this point right here is 3 plus h. And I keep it abstract as h because as you know we're going to take the limit as h approaches 0.
It's 3 plus h squared, right? Because the function is f of x is equal to x squared. So this point right here is 3 plus h, 3 plus h squared.
I really have to find a better tool. This one keeps freezing, I think it's too CPU intensive. But anyway.
We're left with-- this pen keeps freezing-- it's 6h plus h squared over h. And now we would simplify this, right, because we can divide the top and the bottom, that numerator and the denominator by h. And you get 6 plus h squared.
So if you actually did a traditional rise over run, the slope, this change in y over change in x is 6. So we have the instantaneous slope at exactly the point x is equal to 3. So that's useful.
Don't take my word on it on Lagrange. You might want to look it up on Wikipedia. But this [UNlNTELLlGIBLE] derivative of f of x is f prime of x.
So the slope is equal to 32. Whatever the x value is you just put into this f prime of x function or the derivative function, and you'll get the slope at that point. I think that's pretty neat and I'll show you how in future presentations how we can apply this to physics and optimization problems and a whole other set of things.

99:59:59,000 --> 99:59:59,000 1276 99:59:59,000 --> 99:59:59,000
But just going back to that problem we were doing, actually
So if this is my y-axis, this is my x-axis, and the equation-- draw it straight-- that's my x-axis, and then I actually have a circle tool, let me see if I can use it effectively-- well, close enough. There you go.
I think you get the point.
This is just going to be the upper half of the circle.
Actually, I should probably just undo that circle tool and try to draw it by hand.
So it will be the positive x quadrant-- and then actually, I should have drawn the whole hemisphere.
But anyway.
Actually, let me do that, because I think it'll make-- edit, undo, let me clear all of this out.
Sorry for wasting your time, but I think it'll be effective.
OK.
So let me redraw.
So this, that's the y-axis, that's my x-axis, and then this-- the square root is, since it's a function, it can only have one value, so we assume it's defined as the positive square root.
So if we were to graph that, it would look like this.
Something like that, where this would be minus r and that's r.
Afflictions Are Avoided By Following Celibacy
Today, our subject is celibacy (brahmacharya) avoids afflictions (klesh) following brahmacharya avoids klesh This is Dada's very own unique finding That, in this time (kaal) only through this Akram path in this worldy life (sansar) one may be married and yet on the path of moksha
they will go through it, in the very same way as a celibate (brahmachari).
This whole doctrine (siddhant) has been revealed regarding brahmacharya And this one particular siddhant has been revealed That due to sexuality (vishay) a lot of klesh arises and due to brahmacharya one becomes free from all kinds of klesh
Because after taking gnan, after achieving the state of the pure Soul (shuddhatma)
vishay doesn't stop immediately for mahatmas But it becomes insipid It becomes insipid on its own
If that wasn't there - a lot [of klesh] would subside if gross (sthool) vishay ends then too [klesh] would become less Then they can stay like friends friendly companions
so we just have to acquire this understanding Everything will happen today - not like that But what is the correct understanding try to properly fit that understanding
There is tremendous abhorrence (dwesh)
How can one get out of dwesh? One cannot find its root How can one know that the root cause is vishay
How does it work?
There is attachment due to vishay Attachment due to vishay That is called raag
If these expectations don't get fulfilled then there are tremendous reactions and dwesh arises "She did that to me" "I do so much for her"
Possessiveness definitely still exists Always, A husband will have possessiveness over the wife
that brings a lot of klesh it gives a lot of internal suffering (bhogwato) Even in the slightest, if she feels that, "my husband listens to me a lot less and he listens to his mom a lot more or that he listens to his sister more" then an outburst will occur that is considered possessiveness
Dada has said "Vishay is not poison, but fearlessness in vishay is poison. therefore be scared of vishay". Stay aware against it
How much peace would one feel, The mind will feel so light But [in this case] the entire energies of the chit, strength of the mind, all of these get fractured to that extent that if a person has indulged in sexual intercourse even once then for three days after that, the person cannot concentrate on anything if he were to sit to do samayik, nothing would be seen
Even if starts for a minute or two then it [chit] will starts jumping and roaming elsewhere this is how it is... now this is something you didn't know On one side the faults of vishay are happening full-fledged On the other hand the person will say "I can't see any of my mistakes"
It [vishay] has to leave even from the sookshma level
And even beyond that at an even more subtle (sookshma) level
There is the need for security (hunf) based on this one support of hunf, the entire "vishay" exists [in a relationship] gross vishay is the result of hunf
Once this hunf goes away as well, then the thoughts related to vishay will end then the tuber (gaanth) of vishay will be destroyed so until hunf remains, it [vishay] will not stop Do you understand? At the gross (sthool) level it has stopped but in the subtle (sookshma) level this [need for] support (aadhar), hunf (need for security), sustaining support (teko) hunf is very subtle (sookshma), extremely subtle
Hunf, is very [subtle] One gets married because of hunf to look for hunf, one gets married "I can't live alone"
following brahmacharya avoids klesh and especially for husbands and wives check and see in your own life where is the klesh between the two what kinds of klesh exist and at the root, the vishay that exists infatuation (aasakti) that exists the possessiveness that exists, the hunf that exists What role does it play? And to what extent does it have a hold on us
Welcome to the video on the introduction to differential equations.
As I said earlier, one of the biggest mistakes startup make is confusing strategic alliances and joint partnerships for what you need on day 1. In an existing market, you actually might need these guys, but in a resegment and in certainly a new market, these are needed for early evangelist and so you need to think through. When do I need joint partnerships and when will I be hitting mainstream customers because remember most these partnerships tend to fail.
To motivate the algorithms that we're going to talk about in this unit. Let's go back to the Marvel data again. So here's three superheroes.
What we've seen so far--we've analysed a bunch of different families of graphs, and we've found that for all these examples the number of edges is like Θ(n). It grows linearly with the number of edges. You might wonder at this point, is that all there is in life?
All right, problem 79. What is the domain of the function shown on the graph below? That sounds like fancy word.
And in general, when you plot it on the xy-axis, the domain is all of the x values that you're defined over and the range is all the y values. So the function is a mapping from x to y. So let's see where it's defined when x is equal to 4.
So let's see, 4, 5, 2, 1. This is the domain. That's the set of all numbers for which this function is defined.
From set A to set B. Where A is the domain and B is the range. And this is important thing to realize about a function.
X is equal to 5 could be y is equal to 7. Or x is equal to 5 could be y is equal to 8. We don't know that.
For every value of x, we only have one definition for y. And people often call that the vertical line test. At no point on this graph can I draw a vertical line and it intersects it twice.
That's completely OK. As long as one of these doesn't point to two separate numbers. So that magenta is what that first graph is doing.
D. Next question. I think this is the last.
>> You see this in a situation where you may have a 4000 pixel by 4000 pixel texture that may be fetched from a server. This single fetch can take about 241 milliseconds to download, which is actually pretty fast. If you were actually to chop up that image into smaller little pixels, so, for example, we would create 4,000 separate images, the total load time to request all of those images to occupy the same amount of space would change drastically.
Ladies and gentlemen, at TED we talk a lot about leadership and how to make a movement. So let's watch a movement happen, start to finish, in under three minutes and dissect some lessons from it. First, of course you know, a leader needs the guts to stand out and be ridiculed.
(Laughter) (Applause) And here comes a second follower. Now it's not a lone nut, it's not two nuts -- three is a crowd, and a crowd is news.
They won't stand out, they won't be ridiculed, but they will be part of the in-crowd if they hurry. (Laughter) So, over the next minute, you'll see all of those that prefer to stick with the crowd because eventually they would be ridiculed for not joining in.
(Applause)
Right now is the most exciting time to see new Indian art. Contemporary artists in India are having a conversation with the world like never before.
I thought it might be interesting, even for the many long-time collectors here with us at TED, local collectors, to have an outside view of 10 young Indian artists I wish everyone at TED to know. The first is Bharti Kher.
Our next artist, Balasubramaniam, really stands at the crossroads of sculpture, painting and installation, working wonders with fiberglass. Since Bala himself will be speaking at TED I won't spend too much time on him here today, except to say that he really succeeds at making the invisible visible.
Brooklyn-based Chitra Ganesh is known for her digital collages, using Indian comic books called amar chitra kathas as her primary source material. These comics are a fundamental way that children, especially in the diaspora, learn their religious and mythological folk tales.
Jitish Kallat successfully practices across photography, sculpture, painting and installation. As you can see, he's heavily influenced by graffiti and street art, and his home city of Mumbai is an ever-present element in his work. He really captures that sense of density and energy which really characterizes modern urban Bombay.
He uses scale to more and more spectacular effect, whether on the roof of a temple in Singapore, or in his increasingly ambitious installation work, here with 192 functioning sewing machines, fabricating the flags of every member of the United Nations.
Mumbai-based Dhruvi Acharya builds on her love of comic books and street art to comment on the roles and expectations of modern Indian women. She too mines the rich source material of amar chitra kathas, but in a very different way than Chitra Ganesh. In this particular work, she actually strips out the images and leaves the actual text to reveal something previously unseen, and provocative.
Raqib Shaw is Kolkata-born, Kashmir-raised, and London-trained. He too is reinventing the miniature tradition.
I'm kind of cheating with this next artist since Raqs Media Collective are really three artists working together. Raqs are probably the foremost practitioners of multimedia art in India today, working across photography, video and installation. They frequently explore themes of globalization and urbanization, and their home of Delhi is a frequent element in their work.
This next artist is probably the alpha male of contemporary Indian art, Subodh Gupta. He was first known for creating giant photo-realistic canvases, paintings of everyday objects, the stainless steel kitchen vessels and tiffin containers known to every Indian. He celebrates these local and mundane objects globally, and on a grander and grander scale, by incorporating them into ever more colossal sculptures and installations.
And finally number 10, last and certainly not least, Ranjani Shettar, who lives and works here in the state of Karnataka, creates ethereal sculptures and installations that really marry the organic to the industrial, and brings, like Subodh, the local global. These are actually wires wrapped in muslin and steeped in vegetable dye.
10 artists, six minutes, I know that was a lot to take in. But I can only hope I've whet your appetite to go out and see and learn more about the amazing things that are happening in art in India today. Thank you very much for looking and listening.

Let's say we have the indefinite integral of 1 over 36 plus x squared d x. Now, as you can imagine, this is not an easy integral to solve without trigonometry. I can't do u substitution, I don't have the derivative of this thing sitting someplace.
Let's prove this one. Tangent squared of theta, this is equal to 1 plus just the definition of tangent sine squared of theta over cosine squared of theta. Now 1 is just cosine squared over cosine squared.
Not just cosine, the derivative if cosine to the minus 1. So that is minus 1 times cosine to the minus 2 power of theta. That's the derivative of the outside times the derivative of the inside.
The anti-derivative 1 over 36 plus x squared is equal to 1/6 times theta. Theta's just equal to the arctangent x over 6 plus c. And we're done.

Let's take a look at getting customers for physical channel. Now, what does that mean.
Imagine you're JetBlue and you now have a new airline route going from LaGuardia in the United States in New York City down to Orlando, Florida and you really want to get people to know about this new airline route, well the first you're going to use is earned and paid media. You might run TV ads, you might run radio spots, newspapers, or your website, you might send out email and the first thing you're doing with this paid media is you're trying to get people aware that you even have a flight from New York to Orlando. This first step in a physical channel is generating awareness.
Moanin' Low, my sweet man I love him so though he's mean as can be He's the kind of man needs a kind of woman like me a woman like me... a woman like me... a woman like me... Rick wants to hire me!
I think they say the 14th Century. The 14th Century was recently. No, but...I don't know...
Which I don't believe - - but that's what they say. And Ayodhya is in the state of Uttar Pradesh.
3 wives. 3 wives?
4 sons.
4 sons, 3 wives. OK. I know the names of the sons by the way.
Vaidehi, I saw a play called Vaidehi, right, which I learned is another name for Sita. Ram was about to be crowned by Dasharatha as the king and Kaikeyi went to him and because she had done something really good I think she had taken care of him when he was really sick.
And so at that point he had said to her that... "You have one Boon. Anything you ask of me I will do." and so she went and asked him to send Ram away for 14 years thinking that was a long enough time, that if you go away for 14 years, you're pretty much out of sight, out of mind.
He didn't create any problems, he didn't say, "why?" He just said,
If that is your wish Father, I shall go. And then he went.
Maybe they saw them on the moon! Isn't there a Suruphanaka story? Suruphanaka right?
Surphanaka. I'm messing up her name. God, they're gonna be after me
Surphanaka is the one with the really ugly nose.
Surphanaka. But she was Ravana's sister. Ravana!
Her breasts are like big, round, firm, juicy lotuses! Make Sita your wife, Ravana. Steal her from Rama!
Sita WlLL be mine! hahahahaaaa! What a beautiful golden deer! Oh Rama, won't you capture it for me?
Siat! Sita! Oh Sita, what has become of you?
All these demons were attacking the Earth and supposedly all the Gods and everyone went to Vishnu and said "Please help us, please help us!" So Vishnu said he would be born on Earth as Ram. But he was born as Krishna also, this is very confusing.
Like that was the reason for his birth. I will help you. Who are you?
What about Lexi? What about our apartment?
What about US? Don't cry, Nina. I love you.
And so Ravana also comes and says, "what can Ram do for you, blah blah blah, that I can't?" but she's still, "Ram will come here and you still have one last chance"
"because once he comes here, you know, your ass is grass."
I love you Sita. You must be my wife. Never.
The only reason I do not reduce you to ashes with my own blazing power is because Rama has not ordered me to do so. When night is creepin', and I should be sleepin' in bed if you were peepin', you'd find that I'm weepin' instead My lovin' Daddy left his baby again, said he'd come back but he forgot to say when
"and he's virtuous, and he will kill Ravan, and..." Anyway- She's a bloodthirsty woman. SUBLET:
"I will not force you in my house." -right- "I will not force myself on you..." Well he never had sex with her, did he?
I stay home each night when you say you'll phone you don't, and I'm left alone singin' the blues and sighin'. You treat me coldly each day in the year You always scold me whenever somebody is near, dear
5 days, all expenses paid! That's great. It'll be fun for you.
It was like the first - like they flew back.
Maybe they joined the Mile High Club. On the Pushpakh Veman. We don't know exactly when she got pregnant- -Very soon thereafter which is why it's conceivable that she might not have been pregnant because of Ram.
I'm so afraid my man I'm gonna lose. Moanin' low, my sweet man I love him so, though he's mean as can be He's the kind of man needs a kind of woman like me
Makes my troubles double with his worries when surely, I ain't deservin' of none Moanin' low, my sweet man is gonna go, when he goes oh Lordy He's the kind of man needs a kind of woman like me.
Makes my troubles double with his worries when surely I ain't deservin' of none Moanin' low, my sweet man is gonna go, when he goes, Lordy! He's a man that needs a woman just like me.
Luv, Kush, let us sing the praises of Rama. Rama's great, Rama's good, Rama does what Rama should Rama's just, Rama's right, Rama is our guiding light
You know, for her, she was like, ok, "this man, he loves me." This is the part of the female perspective I disagree with.
This eager heart of mine was singing, "Lover where can you be?" You came at last, love had its day
The sky is blue, the night is cold the moon is new, but love is old and while I'm waiting here, this heart of mine is singing, "Lover come back to me." Sky is blue, night is cold, moon is new, but love is old and while I'm waiting here this heart of mine is singing
And when Ram was in the forest he heard these two boys singing, he didn't know who they were but he came up and he was just like, "who are they, who are you?" and that's when he finds out that Sita's there and those are his children.

Since 3 coloring is an NP and SAT is NP complete, meaning that it's NP hard, it has to be the case that we could use SAT to solve 3 coloring problems, but it's actually a little bit interesting to see how you might do that. So let's take a look, here's a simple little graph and one, two, three, four nodes, four edges and imagine that we want to try to 3-color this graph. What we're going to do is we're going to create a ??? formula that is satisfiable if and only if this graph is 3 colorable, so that it's really the same problem, and the way that we're going to do that is we're going to create a bunch of boolean variables, 12 of them to be exact, corresponding to each of the four nodes--a, b, c, and d, and for each node, we'll a boolean variable saying whether that node is red or green or yellow, the three colors.
I want to make a quick correction to the last video. It doesn't really affect the learning of the last video, but I just want to make sure that you understand that I got the math a little bit wrong in the last video.

THE ADVENTURES OF SHERLOCK HOLMES by SlR ARTHUR CONAN DOYLE ADVENTURE I. A SCANDAL IN BOHEMlA I. To Sherlock Holmes she is always THE woman.
Odessa in the case of the Trepoff murder, of his clearing up of the singular tragedy of the Atkinson brothers at Trincomalee, and finally of the mission which he had accomplished so delicately and successfully for the reigning family of Holland. Beyond these signs of his activity, however, which I merely shared with all the readers of the daily press, I knew little of my former friend and companion. One night--it was on the twentieth of March, 1888--I was returning from a journey to a patient (for I had now returned to civil practice), when my way led me through
"I see it, I deduce it. How do I know that you have been getting yourself very wet lately, and that you have a most clumsy and careless servant girl?"
"My dear Holmes," said I, "this is too much. You would certainly have been burned, had you lived a few centuries ago. It is true that I had a country walk on Thursday and came home in a dreadful mess, but as I have changed my clothes I can't imagine how you deduce it.
"Quite so," he answered, lighting a cigarette, and throwing himself down into an armchair. "You see, but you do not observe. The distinction is clear.
"How often?" "Well, some hundreds of times." "Then how many are there?"
"Quite so! You have not observed. And yet you have seen.
"This is indeed a mystery," I remarked. "What do you imagine that it means?" It is a capital mistake to theorize before one has data.
"t" woven into the texture of the paper. "What do you make of that?" asked Holmes. "The name of the maker, no doubt; or his monogram, rather."
The 'G' with the small 't' stands for 'Gesellschaft,' which is the German for
'Company.' It is a customary contraction like our
'Co.'
'P,' of course, stands for 'Papier.' Now for the 'Eg.' Let us glance at our Continental Gazetteer."
"Eglow, Eglonitz--here we are, Egria. It is in a German-speaking country--in Bohemia, not far from Carlsbad.
'Remarkable as being the scene of the death of Wallenstein, and for its numerous glass- factories and paper-mills.' Ha, ha, my boy, what do you make of that?" His eyes sparkled, and he sent up a great blue triumphant cloud from his cigarette.
"Not a bit, Doctor. Stay where you are. I am lost without my Boswell.
"But your client--"
"Never mind him. I may want your help, and so may he. Here he comes.
"You may address me as the Count Von Kramm, a Bohemian nobleman. I understand that this gentleman, your friend, is a man of honour and discretion, whom I may trust with a matter of the most extreme importance. If not, I should much prefer to communicate with you alone."
At present it is not too much to say that it is of such weight it may have an influence upon European history." "I promise," said Holmes.
"And I."
"You will excuse this mask," continued our strange visitor. "The august person who employs me wishes his agent to be unknown to you, and I may confess at once that the title by which I have just called myself is not exactly my own." "I was aware of it," said Holmes dryly.
"Why, indeed?" murmured Holmes. "Your Majesty had not spoken before I was aware that I was addressing Wilhelm
Gottsreich Sigismond von Ormstein, Grand Duke of Cassel-Felstein, and hereditary King of Bohemia."
"But you can understand," said our strange visitor, sitting down once more and passing his hand over his high white forehead, "you can understand that I am not accustomed to doing such business in my own person. Yet the matter was so delicate that I could not confide it to an agent without putting myself in his power. I have come incognito from Prague for the purpose of consulting you."
"Then, pray consult," said Holmes, shutting his eyes once more. "The facts are briefly these: Some five years ago, during a lengthy visit to
"Kindly look her up in my index, Doctor," murmured Holmes without opening his eyes. For many years he had adopted a system of docketing all paragraphs concerning men and things, so that it was difficult to name a subject or a person on which he could not at once furnish information. In this case I found her biography sandwiched in between that of a Hebrew rabbi and that of a staff-commander who had written a monograph upon the deep-sea fishes.
"Precisely so. But how--" "Was there a secret marriage?" "None."
"There is the writing." "Pooh, pooh! Forgery."
"My private note-paper." "Stolen."
"My own seal." "Imitated." "My photograph."
Your Majesty has indeed committed an indiscretion."
"She will not sell." "Stolen, then." "Five attempts have been made.
"To ruin me." "But how?"
"I am about to be married." "So I have heard." You may know the strict principles of her family.
"I am sure." "And why?" "Because she has said that she would send it on the day when the betrothal was publicly proclaimed.
"Certainly. You will find me at the Langham under the name of the Count Von Kramm." "Then I shall drop you a line to let you know how we progress."
"Pray do so. I shall be all anxiety."
"Then, as to money?" "You have carte blanche." "Absolutely?"
"And Mademoiselle's address?" he asked. "Is Briony Lodge, Serpentine Avenue, St. John's Wood."
"Then, good-night, your Majesty, and I trust that we shall soon have some good news for you. And good-night, Watson," he added, as the wheels of the royal brougham rolled down the street. "If you will be good enough to call to- morrow afternoon at three o'clock I should
"I can't imagine. I suppose that you have been watching the habits, and perhaps the house, of Miss "Quite so; but the sequel was rather unusual.
Chubb lock to the door. Large sitting-room on the right side, well furnished, with long windows almost to the floor, and those preposterous English window fasteners which a child could open. Behind there was nothing remarkable, save that the passage window could be reached from the top of the coach-house.
"And what of Irene Adler?" I asked. "Oh, she has turned all the men's heads down in that part.
Briony Lodge once more, and to think over my plan of campaign. "This Godfrey Norton was evidently an important factor in the matter. He was a lawyer.
"I am following you closely," I answered. "I was still balancing the matter in my mind when a hansom cab drove up to Briony Lodge, and a gentleman sprang out.
"Away they went, and I was just wondering whether I should not do well to follow them when up the lane came a neat little landau, the coachman with his coat only half- buttoned, and his tie under his ear, while all the tags of his harness were sticking out of the buckles. It hadn't pulled up before she shot out of the hall door and into it. I only caught a glimpse of her at the moment, but she was a lovely woman, with a face that a man might die for. "'The Church of St. Monica, John,' she cried, 'and half a sovereign if you reach it in twenty minutes.'
"This is a very unexpected turn of affairs," said I; "and what then?" "Well, I found my plans very seriously menaced. It looked as if the pair might take an immediate departure, and so necessitate very prompt and energetic measures on my part.
"Which are?" "Some cold beef and a glass of beer," he answered, ringing the bell. "I have been too busy to think of food, and I am likely to be busier still this evening.
"I shall be delighted." "You don't mind breaking the law?" "Not in the least."
"Oh, the cause is excellent!" "Then I am your man."
"I was sure that I might rely on you." "But what is it you wish?" "When Mrs. Turner has brought in the tray I will make it clear to you.
"I must discuss it while I eat, for I have not much time. It is nearly five now. In two hours we must be on the scene of action.
"And what then?" "You must leave that to me. I have already arranged what is to occur.
"I am to be neutral?" "To do nothing whatever. There will probably be some small unpleasantness.
"Yes." "You are to watch me, for I will be visible to you." "Yes."
"Entirely." "It is nothing very formidable," he said, taking a long cigar-shaped roll from his pocket. "It is an ordinary plumber's smoke-rocket, fitted with a cap at either end to make it self-lighting.
"I am to remain neutral, to get near the window, to watch you, and at the signal to throw in this object, then to raise the cry of fire, and to wait you at the corner of the street."
"Precisely." "Then you may entirely rely on me."
I think, perhaps, it is almost time that I prepare for the new role I have to play."
It was already dusk, and the lamps were just being lighted as we paced up and down in front of Briony Lodge, waiting for the coming of its occupant. The house was just such as I had pictured it from Sherlock Holmes' succinct description, but the locality appeared to be less private than I expected. On the contrary, for a small street in a quiet neighbourhood, it was remarkably animated.
"Where, indeed?" "It is most unlikely that she carries it about with her. It is cabinet size.
"But it has twice been burgled." "Pshaw! They did not know how to look."
"But she will refuse." "She will not be able to. But I hear the rumble of wheels.
A fierce quarrel broke out, which was increased by the two guardsmen, who took sides with one of the loungers, and by the scissors-grinder, who was equally hot upon the other side. A blow was struck, and in an instant the lady, who had stepped from her carriage, was the centre of a little knot of flushed and struggling men, who struck savagely at each other with their fists and sticks. Holmes dashed into the crowd to protect the lady; but just as he reached her he gave a cry and dropped to the ground, with the blood running freely down his face.
"He's a brave fellow," said a woman. "They would have had the lady's purse and watch if it hadn't been for him. They were a gang, and a rough one, too.
"He can't lie in the street. May we bring him in, marm?"
"Surely. Bring him into the sitting-room. There is a comfortable sofa.
"Fire!" Thick clouds of smoke curled through the room and out at the open window. I caught a glimpse of rushing figures, and a moment later the voice of Holmes from within assuring them that it was a false alarm.
"You have the photograph?" "I know where it is." "And how did you find out?"
"I do not wish to make a mystery," said he, laughing. "The matter was perfectly simple. You, of course, saw that everyone in the street was an accomplice.
"Then, when the row broke out, I had a little moist red paint in the palm of my hand. I rushed forward, fell down, clapped my hand to my face, and became a piteous spectacle. It is an old trick."
"That also I could fathom." "Then they carried me in. She was bound to have me in.
In the case of the Darlington substitution scandal it was of use to me, and also in the Arnsworth Castle business.
A married woman grabs at her baby; an unmarried one reaches for her jewel-box. Now it was clear to me that our lady of to- day had nothing in the house more precious to her than what we are in quest of. She would rush to secure it.
"And now?" I asked. "Our quest is practically finished.
"And when will you call?" "At eight in the morning. She will not be up, so that we shall have a clear field.
IIl. I slept at Baker Street that night, and we were engaged upon our toast and coffee in the morning when the King of Bohemia rushed into the room. "You have really got it!" he cried, grasping Sherlock Holmes by either shoulder and looking eagerly into his face.
"No, my brougham is waiting." "Then that will simplify matters." We descended and started off once more for
Briony Lodge.
"But to whom?" "To an English lawyer named Norton." "But she could not love him."
"It is true. And yet--Well! I wish she had been of my own station!
The door of Briony Lodge was open, and an elderly woman stood upon the steps.
"What!" Sherlock Holmes staggered back, white with chagrin and surprise. "Do you mean that she has left England?"
"What a woman--oh, what a woman!" cried the King of Bohemia, when we had all three read this epistle. "Did I not tell you how quick and resolute she was? Would she not have made an admirable queen?
"From what I have seen of the lady she seems indeed to be on a very different level to your Majesty," said Holmes coldly. "I am sorry that I have not been able to bring your Majesty's business to a more successful conclusion."
"Irene's photograph!" he cried. "Certainly, if you wish it." "I thank your Majesty.
"Not at all. This gentleman, Mr. Wilson, has been my partner and helper in many of my most successful cases, and I have no doubt that he will be of the utmost use to me in yours also." The stout gentleman half rose from his chair and gave a bob of greeting, with a quick little questioning glance from his small fat-encircled eyes.
"Your cases have indeed been of the greatest interest to me," I observed. "You will remember that I remarked the other day, just before we went into the very simple problem presented by Miss Mary Sutherland, that for strange effects and extraordinary combinations we must go to life itself, which is always far more daring than any effort of the imagination."
"A proposition which I took the liberty of doubting." "You did, Doctor, but none the less you must come round to my view, for otherwise I shall keep on piling fact upon fact on you until your reason breaks down under them and acknowledges me to be right. Now, Mr. Jabez Wilson here has been good enough to call upon me this morning, and to begin a narrative which promises to be one of the most singular which I have listened to for some time.
"Your hands, my dear sir. Your right hand is quite a size larger than your left. You have worked with it, and the muscles are more developed."
"Well, the snuff, then, and the Freemasonry?" "I won't insult your intelligence by telling you how I read that, especially as, rather against the strict rules of your order, you use an arc-and-compass breastpin."
"Ah, of course, I forgot that. But the writing?" "What else can be indicated by that right cuff so very shiny for five inches, and the
"Well, but China?" "The fish that you have tattooed immediately above your right wrist could only have been done in China. I have made a small study of tattoo marks and have even contributed to the literature of the subject.
"I thought at first that you had done something clever, but I see that there was nothing in it, after all." "I begin to think, Watson," said Holmes, "that I make a mistake in explaining.
"Yes, I have got it now," he answered with his thick red finger planted halfway down the column. "Here it is. This is what began it all.
"It is The Morning Chronicle of April 27, 1890. Just two months ago." "Very good.
"What is the name of this obliging youth?" asked Sherlock Holmes. "His name is Vincent Spaulding, and he's not such a youth, either. It's hard to say his age.
"Why, indeed? You seem most fortunate in having an employé who comes under the full market price. It is not a common experience among employers in this age.
"Oh, he has his faults, too," said Mr. Wilson. "Never was such a fellow for photography. Snapping away with a camera when he ought to be improving his mind, and then diving down into the cellar like a rabbit into its hole to develop his pictures.
"Yes, sir. He and a girl of fourteen, who does a bit of simple cooking and keeps the place clean--that's all I have in the house, for I am a widower and never had any family. We live very quietly, sir, the three of us; and we keep a roof over our heads and pay our debts, if we do nothing more.
Spaulding, he came down into the office just this day eight weeks, with this very paper in his hand, and he says: "'I wish to the Lord, Mr. Wilson, that I was a red-headed man.' "'Why that?'
I asks. "'Why,' says he, 'here's another vacancy on the League of the Red-headed Men. It's worth quite a little fortune to any man who gets it, and I understand that there are more vacancies than there are men, so that the trustees are at their wits' end what to do with the money. If my hair would only change colour, here's a nice little crib all ready for me to step into.' "'Why, what is it, then?'
"'Well,' said he, showing me the advertisement, 'you can see for yourself that the League has a vacancy, and there is the address where you should apply for particulars. As far as I can make out, the League was founded by an American millionaire, Ezekiah Hopkins, who was very peculiar in his ways.
From all I hear it is splendid pay and very little to do.' "'But,' said I, 'there would be millions of red-headed men who would apply.' "'Not so many as you might think,' he answered. 'You see it is really confined to Londoners, and to grown men. This American had started from London when he was young, and he wanted to do the old town a good turn.
"Now, it is a fact, gentlemen, as you may see for yourselves, that my hair is of a very full and rich tint, so that it seemed to me that if there was to be any competition in the matter I stood as good a chance as any man that I had ever met. Vincent Spaulding seemed to know so much about it that I thought he might prove useful, so I just ordered him to put up the shutters for the day and to come right away with me. He was very willing to have a holiday, so we shut the business up and started off for the address that was given us in the advertisement.
"Your experience has been a most entertaining one," remarked Holmes as his client paused and refreshed his memory with a huge pinch of snuff. "Pray continue your very interesting statement." "There was nothing in the office but a couple of wooden chairs and a deal table, behind which sat a small man with a head that was even redder than mine.
"I answered that I had not. "His face fell immediately. "'Dear me!' he said gravely, 'that is very serious indeed! I am sorry to hear you say that.
"My face lengthened at this, Mr. Holmes, for I thought that I was not to have the vacancy after all; but after thinking it over for a few minutes he said that it would be all right. "'In the case of another,' said he, 'the objection might be fatal, but we must stretch a point in favour of a man with such a head of hair as yours.
When shall you be able to enter upon your new duties?' "'Well, it is a little awkward, for I have a business already,' said I.
"'Oh, never mind about that, Mr. Wilson!' said Vincent Spaulding. 'I should be able to look after that for you.' "'What would be the hours?' I asked. "'Ten to two.'
'And the pay?' "'Is 4 pounds a week.' "'And the work?' "'Is purely nominal.' "'What do you call purely nominal?' "'Well, you have to be in the office, or at least in the building, the whole time. If you leave, you forfeit your whole position forever. The will is very clear upon that point.
You don't comply with the conditions if you budge from the office during that time.' "'It's only four hours a day, and I should not think of leaving,' said I.
"'No excuse will avail,' said Mr. Duncan Ross; 'neither sickness nor business nor anything else.
There you must stay, or you lose your billet.' "'And the work?' "'Is to copy out the "Encyclopaedia There is the first volume of it in that press.
Will you be ready to-morrow?' "'Certainly,' I answered. "'Then, good-bye, Mr. Jabez Wilson, and let me congratulate you once more on the important position which you have been fortunate enough to gain.' He bowed me out of the room and I went home with my assistant, hardly knowing what to say or do, I was so pleased at my own good fortune. "Well, I thought over the matter all day, and by evening I was in low spirits again; for I had quite persuaded myself that the whole affair must be some great hoax or fraud, though what its object might be I could not imagine.
"To an end?" "Yes, sir. And no later than this morning.
October 9, 1890. Sherlock Holmes and I surveyed this curt announcement and the rueful face behind it, until the comical side of the affair so completely overtopped every other consideration that we both burst out into a roar of laughter. "I cannot see that there is anything very funny," cried our client, flushing up to the roots of his flaming head.
"I was staggered, sir. I did not know what to do. Then I called at the offices round, but none of them seemed to know anything about it.
He moved out yesterday.' "'Where could I find him?' "'Oh, at his new offices. He did tell me the address. Yes, 17 King Edward Street, near St. Paul's.'
"And what did you do then?" asked Holmes. "I went home to Saxe-Coburg Square, and I took the advice of my assistant. But he could not help me in any way.
"And you did very wisely," said Holmes. "Your case is an exceedingly remarkable one, and I shall be happy to look into it. From what you have told me I think that it is possible that graver issues hang from it than might at first sight appear."
"We shall endeavour to clear up these points for you. And, first, one or two questions, Mr. Wilson. This assistant of yours who first called your attention to the advertisement--how
"About a month then." "How did he come?"
"In answer to an advertisement." "Was he the only applicant?"
"No, I had a dozen." "Why did you pick him?" "Because he was handy and would come cheap."
"Yes." "What is he like, this Vincent Spaulding?" "Small, stout-built, very quick in his ways, no hair on his face, though he's not short of thirty.
"Hum!" said Holmes, sinking back in deep thought. "He is still with you?" "Oh, yes, sir; I have only just left him."
"That will do, Mr. Wilson. I shall be happy to give you an opinion upon the subject in the course of a day or two. To-day is Saturday, and I hope that by Monday we may come to a conclusion."
"Well, Watson," said Holmes when our visitor had left us, "what do you make of it all?"
"I make nothing of it," I answered frankly. "It is a most mysterious business." "As a rule," said Holmes, "the more bizarre a thing is the less mysterious it proves to be.
"What are you going to do, then?" I asked. "To smoke," he answered.
"I have nothing to do to-day. My practice is never very absorbing."
"Then put on your hat and come. I am going through the City first, and we can have some lunch on the way. I observe that there is a good deal of German music on the programme, which is rather more to my taste than Italian or French.
Saxe-Coburg Square, the scene of the singular story which we had listened to in the morning. It was a poky, little, shabby-genteel place, where four lines of dingy two- storied brick houses looked out into a small railed-in enclosure, where a lawn of weedy grass and a few clumps of faded laurel-bushes made a hard fight against a smoke-laden and uncongenial atmosphere.
"Thank you," said Holmes, "I only wished to ask you how you would go from here to the
Strand." "Third right, fourth left," answered the assistant promptly, closing the door. "Smart fellow, that," observed Holmes as we walked away.
"Not him." "What then?" "The knees of his trousers."
"Why did you beat the pavement?" "My dear doctor, this is a time for observation, not for talk. We are spies in an enemy's country.
Saxe-Coburg Square presented as great a contrast to it as the front of a picture does to the back. It was one of the main arteries which conveyed the traffic of the City to the north and west. The roadway was blocked with the immense stream of commerce flowing in a double tide inward and outward, while the footpaths were black with the hurrying swarm of pedestrians.
This business at Coburg Square is serious." "Why serious?" "A considerable crime is in contemplation.
"Ten will be early enough." "I shall be at Baker Street at ten." "Very well.
Coburg Square, and the ominous words with which he had parted from me. What was this nocturnal expedition, and why should I go armed? Where were we going, and what were we to do?
"We're hunting in couples again, Doctor, you see," said Jones in his consequential way. "Our friend here is a wonderful man for starting a chase. All he wants is an old dog to help him to do the running down."
"I hope a wild goose may not prove to be the end of our chase," observed Mr. Merryweather gloomily. "You may place considerable confidence in Mr. Holmes, sir," said the police agent
loftily. "He has his own little methods, which are, if he won't mind my saying so, just a little too theoretical and fantastic, but he has the makings of a detective in him.
"Oh, if you say so, Mr. Jones, it is all right," said the stranger with deference. "Still, I confess that I miss my rubber. It is the first Saturday night for seven- and-twenty years that I have not had my rubber."
"John Clay, the murderer, thief, smasher, and forger.
He's a young man, Mr. Merryweather, but he is at the head of his profession, and I would rather have my bracelets on him than on any criminal in London.
He's a remarkable man, is young John Clay. His grandfather was a royal duke, and he himself has been to Eton and Oxford. His brain is as cunning as his fingers, and though we meet signs of him at every turn, we never know where to find the man himself.
He'll crack a crib in Scotland one week, and be raising money to build an orphanage in Cornwall the next. I've been on his track for years and have never set eyes on him yet."
"I hope that I may have the pleasure of introducing you to-night. I've had one or two little turns also with Mr. John Clay, and I agree with you that he is at the head of his profession. It is past ten, however, and quite time that we started.
Farrington Street. I thought it as well to have Jones with us also.
"It is our French gold," whispered the director. "We have had several warnings that an attempt might be made upon it." We had occasion some months ago to strengthen our resources and borrowed for that purpose 30,000 napoleons from the Bank of France.
"Which were very well justified," observed Holmes. "And now it is time that we arranged our little plans. I expect that within an hour matters will come to a head.
"And sit in the dark?" "I am afraid so. I had brought a pack of cards in my pocket, and I thought that, as we were a partie carrée, you might have your rubber after all.
"I have an inspector and two officers waiting at the front door." "Then we have stopped all the holes. And now we must be silent and wait."
"I beg that you will not touch me with your filthy hands," remarked our prisoner as the handcuffs clattered upon his wrists. "You may not be aware that I have royal blood in my veins. Have the goodness, also, when you address me always to say 'sir' and 'please.'"
"All right," said Jones with a stare and a snigger. "Well, would you please, sir, march upstairs, where we can get a cab to carry your Highness to the police-station?"
"That is better," said John Clay serenely. He made a sweeping bow to the three of us and walked quietly off in the custody of the detective. "Really, Mr. Holmes," said Mr. Merryweather as we followed them from the cellar, "I do not know how the bank can thank you or repay you.
"I have had one or two little scores of my own to settle with Mr. John Clay," said Holmes. "I have been at some small expense over this matter, which I shall expect the bank to refund, but beyond that I am amply repaid by having had an experience which is in many ways unique, and by hearing the very remarkable narrative of the Red-headed League."
"You see, Watson," he explained in the early hours of the morning as we sat over a glass of whisky and soda in Baker Street, "it was perfectly obvious from the first that the only possible object of this rather fantastic business of the advertisement of the League, and the copying of the 'Encyclopaedia,' must be to get this not over-bright pawnbroker out of the way for a number of hours every day. It was a curious way of managing it, but, really, it would be difficult to suggest a better. The method was no doubt suggested to Clay's ingenious mind by the colour of his accomplice's hair.
The 4 pounds a week was a lure which must draw him, and what was it to them, who were playing for thousands? They put in the advertisement, one rogue has the temporary office, the other rogue incites the man to apply for it, and together they manage to secure his absence every morning in the week. From the time that I heard of the assistant having come for half wages, it was obvious to me that he had some strong motive for securing the situation."
"But how could you guess what the motive was?" "Had there been women in the house, I should have suspected a mere vulgar intrigue. That, however, was out of the question.
"And how could you tell that they would make their attempt to-night?" I asked. "Well, when they closed their League offices that was a sign that they cared no
"You reasoned it out beautifully," I exclaimed in unfeigned admiration. "It is so long a chain, and yet every link rings true." "It saved me from ennui," he answered, yawning.
There are some other things to consider in customer segments besides jobs to be done and pain and gain, and that is--who's the customer? Gee, I thought we're just defined the customers, it's the archetype, it's the persona but sometimes who's the customer in context is really what we need to know. In corporations, it's pretty easy to understand that you might have someone who uses the product but they might not be the person who pays for the product.
"Dad, you can't buy that type of car. We wouldn't be caught dead on it." I looked at them and I said, well the car is not for you.
"Well, listen if you buy that car, you can't get that color, " and this conversation went on for a long time until finally we're able to make a decision and I realized that the final decision-maker in our household was my wife.

So, a couple of tips. Number 1: The Business Model Canvas is a scorecard; it's not the class.
Why do startups fail? Well, the answer is really all of the above. Co-founders do fight.
So a useful thing to know about a social network is whether everything is connected to everything else or whether there's some subset of nodes that's isolated from the main body of nodes. To put it in another way: whether any given pair of nodes in the network can communicate by passing messages from friend to friend, from one place to another. So this graph is actually separated into two different components.
I have given the slide show that I gave here two years ago about 2,000 times. I'm giving a short slide show this morning that I'm giving for the very first time, so -- well it's -- I don't want or need to raise the bar, I'm actually trying to lower the bar.
"You must become the change you wish to see in the world." And the outcome about which we wish to be optimistic is not going to be created by the belief alone, except to the extent that the belief brings about new behavior. But the word "behavior" is also, I think, sometimes misunderstood in this context.
Many years ago, when I was a young congressman, I spent an awful lot of time dealing with the challenge of nuclear arms control -- the nuclear arms race. And the military historians taught me, during that quest, that military conflicts are typically put into three categories: local battles, regional or theater wars, and the rare but all-important global, world war -- strategic conflicts.
"They were the best of times, they were the worst of times": the most famous opening sentence in English literature. I want to share briefly a tale of two planets. Earth and Venus are exactly the same size.
"How certain are you?" They wanted to answer that "99 percent." The Chinese objected, and so the compromise was
"more than 90 percent." Now, the skeptics say, "Oh, wait a minute, this could be variations in this energy coming in from the sun." If that were true, the stratosphere would be heated as well as the lower atmosphere, if it's more coming in.
NBC -- I'll show all of the networks here -- the top journalists for NBC asked 956 questions in 2007 of the presidential candidates: two of them were about the climate crisis.
ABC: 844 questions, two about the climate crisis. Fox: two.
This is peak fishing in a few seconds. The '60s. '70s.
-- and now there's only one. Australia had an election. And there was a campaign in Australia that involved television and Internet and radio commercials to lift the sense of urgency for the people there.
The cities supporting Kyoto in the U.S. are up to 780 -- and I thought I saw one go by there, just to localize this -- which is good news. Now, to close, we heard a couple of days ago about the value of making individual heroism so commonplace that it becomes banal or routine. What we need is another hero generation.
Those of us who are alive in the United States of America today especially, but also the rest of the world, have to somehow understand that history has presented us with a choice -- just as Jill [Bolte] Taylor was figuring out how to save her life while she was distracted by the amazing experience that she was going through. We now have a culture of distraction.
One final point: I'm optimistic, because I believe we have the capacity, at moments of great challenge, to set aside the causes of distraction and rise to the challenge that history is presenting to us. Sometimes I hear people respond to the disturbing facts of the climate crisis by saying, "Oh, this is so terrible.
Chris Anderson:
For so many people at TED, there is deep pain that basically a design issue on a voting form -- one bad design issue meant that your voice wasn't being heard like that in the last eight years in a position where you could make these things come true. That hurts.
The answer to the question is hard for me because, on the one hand, I think that we should feel really great about the fact that the Republican nominee -- certain nominee --
"Clean Coal." Has anybody noticed that? Every single debate has been sponsored by "Clean Coal."
"Now, even lower emissions!" The richness and fullness of the dialogue in our democracy has not laid the basis for the kind of bold initiative that is really needed. So they're saying the right things and they may -- whichever of them is elected -- may do the right thing, but let me tell you: when I came back from Kyoto in 1997, with a feeling of great happiness that we'd gotten that breakthrough there, and then confronted the United States Senate, only one out of 100 senators was willing to vote to confirm, to ratify that treaty.
CO2 is the exhaling breath of our civilization, literally. And now we mechanized that process. Changing that pattern requires a scope, a scale, a speed of change that is beyond what we have done in the past.
I'm here to talk to you about how globalized we are, how globalized we aren't, and why it's important to actually be accurate in making those kinds of assessments. And the leading point of view on this, whether measured by number of books sold, mentions in media, or surveys that I've run with groups ranging from my students to delegates to the World Trade Organization, is this view that national borders really don't matter very much anymore, cross-border integration is close to complete, and we live in one world. And what's interesting about this view is, again, it's a view that's held by pro-globalizers
"Just how global are we?" before we think about where we go from here. So the best way I've found of trying to get people to take seriously the idea that the world may not be flat, may not even be close to flat, is with some data. So one of the things I've been doing over the last few years is really compiling data on things that could either happen within national borders or across national borders, and I've looked at the cross-border component as a percentage of the total.
"World 3.0," that we're very, very far from the no-border effect benchmark, which would imply internationalization levels of the order of 85, 90, 95 percent. So clearly, apocalyptically-minded authors have overstated the case. But it's not just the apocalyptics, as I think of them, who are prone to this kind of overstatement.
(Laughter) Second, these are pretty large errors. For four quantities whose average value is less than 10 percent, you have people guessing three, four times that level.
"Why the World Isn't Flat," that wasn't too surprising.
(Laughter) What was very surprising to me was Tom's critique, which was, "Ghemawat's data are narrow." And this caused me to scratch my head, because as I went back through his several-hundred-page book,
"Professor Ghemawat, why do you still believe that the world is round?" And I started laughing, because I hadn't come across that formulation before. (Laughter)
And as I was laughing, I was thinking, I really need a more coherent response, especially on national TV. I'd better write something about this.
(Laughter) But what I can't quite capture for you was the pity and disbelief with which the interviewer asked her question. The perspective was, here is this poor professor.
"Yeah, but what about Facebook?" And I got this question often enough that I thought I'd better do some research on Facebook.
"Foreign aid is the most aid to poor people," is about the most home-biased thing you can find. If you look at the OECD countries and how much they spend per domestic poor person, and compare it with how much they spend per poor person in poor countries, the ratio — Branko Milanovic at the World Bank did the calculations — turns out to be about 30,000 to one. Now of course, some of us, if we truly are cosmopolitan, would like to see that ratio being brought down to one-is-to-one.
Thank you very much. (Applause) (Applause)
In this video we're going to talk about the French, the French Revolution. And what makes this especially significant is that not only is this independence from a monarchy-controlled empire, like in the American Independence, this is an actual overthrowing of a monarchy, of a monarchy that controls a major world power.
France-was-poor. Now, you wouldn't think that France was poor if you looked at Louis XVl, who was King of France,
If you looked at Louis XVI and the clothes he wore. If you looked at Marie-Antoinette, his wife, they don't look poor. They lived in the palace of Versailles which is ginormous.
But at the time it was a village 20 or 30 kilometers away from Paris. So they don't seem to be poor. But the actual government of France is poor.
And for those of you who are more American history focused, the Seven Years' War is really the same thing as the French and Indian War. The French and Indian War was the North American theater of the Seven Years' War. But the Seven Years' War is the more general term.
Because there was also a conflict going on in Europe simultaneously. The French and Indian War was just part of that conflict.
And the Seven Years' actually engulfed most of the powers of Europe at the time. So France had participated in this, ended in 1763, you had the American Revolution. Both of these really just drained the amount of funds that the government itself had.
And obviously, the biggest proof of the Enlightenment was the American Revolution.
That was kind of the first example of people rising up and saying, we don't need these kings anymore. We want to govern ourselves.
For the people, by the people.
I think the people starving.
People said, oh there's Enlightenment movement here. So this is the state of France. They had a financial crisis.
You can really just view them as the three major social classes of France. The First Estate was the clergy. The Second Estate is the nobility.
But these people had the burden of most of the taxes. These are the people who are doing all the work, producing all of France's wealth, dying in the wars. But these guys, despite their small population, have more weight than everybody else.
So you had the Convocation of the Estates-General, where representatives of these Three Estates met, at the Palace of Versailles, to essentially figure out what to do about this fiscal crisis.

Write 14,897 in expanded form. Let me just rewrite the number, and I'll color code it, and that way, we can keep track of our digits. So we have 14,000.
14,000, 800, and 97-- I already used the blue; maybe I should use yellow-- in expanded form. So let's think about what place each of these digits are in. This right here, the 7, is in the ones place.
The 9 is in the tens place.
This literally represents 9 tens, and we're going to see this in a second. This literally represents 7 ones.
The 8 is in the hundreds place.
The 4 is in the thousands place. It literally represents 4,000.
And then the 1 is in the ten-thousands place.
And you see, every time you move to the left, you move one place to the left, you're multiplying by 10. Ones place, tens place, hundreds place, thousands place, ten-thousands place. Now let's think about what that really means.
The 7 literally represents 7 ones.
Or another way to think about it, you could say it represents 7 times 1. All of these are equivalent. They represent 7 ones.
9 actual tens. 9 tens, or you could say it's the same thing as 9 times 10, or 90, either way you want to think about it. So let me write all the different ways to think about it.
Or you could view that as being equivalent to 8 times 100-- a hundred, not a thousand-- 8 times 100, or 800. That 8 literally represents 8 hundreds, 800. And then the 4.
4,000 is the same thing as 4 thousands. Add it up. And then finally, we have this 1, which is sitting in the ten-thousands place, so it literally represents 1 ten-thousand.
You can imagine if these were chips, kind of poker chips, that would represent one of the blue poker chips and each blue poker chip represents 10,000. I don't know if that helps you or not. And 1 ten-thousand is the same thing as 1 times 10,000 which is the same thing as 10,000.
So either of these could be considered expanded form.
Now we're going to do a quiz and what we're going do is try to calculate how much it cost to actually get an active customer and let's start with the pay-per-click. Let's assume we're doing a web company and we spent 75 cents on Google AdWords for every click that comes to our website here. Now assume we actually have figured out that it require 4,025 customers at 75 cents in this campaign.
Let's do a classic problem it really shows up every time you take a flight I had to calculate something like this very recently. Cause I had a flight from San Francisco to new york.
So we are leaving at 9:53 and arrive at 6:26.
So remember this is 9:53am and this is the trick of this problem.
This is san Francisco time, san Fran ,san Francisco time and then you are arriving in new york at 6:26pm but now this isn't San Francisco time, this isn't Pacific Time, this is now eastern time so this is New York time,New York time, and to do this problem something you would have to know is that new york is 3 hours ahead of san Francisco. So this is 3 hours ahead, 3 hours ahead. So when it is noon in san Francisco, it is 3pm in new york , when it is 1pm in san Francisco , it is 4pm in new york and so the trick to doing this type of problem is to really just make sure every thing is in the same time zone.
So to do that, we have to take our our san Francisco time and add 3 hours so plus plus 3 hours, and we have to be careful here because you can say 9 plus 12 that'll go to 12:53 but we have to be careful here because we are no longer at 12:53 am we are now at 12:53 pm and you can draw a number line
I should I should say a timeline here to make that clear.
If you are at 9:53am, 9, 9:53am.
If you go one hour I can draw a longer, a longer, a longer time line over here.
If you are at 9:53,
If you add one hour you are at 10:53 these are am, am.
You add another hour you are at 11:53,11:53.
My handwriting is getting messy, 11 ,11:53am.
And then you add another hour , so our third hour , you are now crossing the threshold from am into pm.
So You are now at 12:53 but it is not it is no longer am. It is now pm.
So one way you could think about this first flight we are leaving San Francisco at 12:53pm eastern time. So now this is new york so this is Eastern Time.
And then we are arriving in new york at 6:26pm eastern time and now we can literally just subtract this time from that time. Especially because they are both pm that "s the easiest way to do it. We could do it with the timeline that would work as well.
But just for simplicity let's take so we are finishing at 6:26pm we started at 12:53, we are starting at 12:53pm and now you might say wait how do you subtract 12:53pm from 6:26pm, and the key here is to put both of them in essentially military time.
This is essentially this is if you put it in military time, this is still going to be this is still going to be 12:53.
If you put this up here in military time you would add 12 to it and so this is going to be 18:26, 18:26.
So I added I added 12 here to put that into military time and now the subtraction becomes pretty straightforward. so you have 6 minus 3 is 3 minutes. You have 2 minus 5 that is essentially 20 minutes minus 50 minutes and right here you're like how do I subtract a larger number from a smaller number and we can borrow or regroup, so we will borrow one hour from the 18 hours, or from this 8 hours right over here, that will become 7 hours. Now we have an hour to put into this spot, an hour is six 10-minute periods, this is our 10 minute spot, so you would add, you would add 6 to this.
'cause we're leaving at 11:42 pm and arriving in San Francisco at 3:19 am the next day.
So once again lets convert everything to eastern time.
So we're leaving at 11, 11:42 pm, and then we're arriving, that's eastern time, and then we're arriving at 3:19 am Pacific time.
If we want to convert that 3:19 to eastern, you add 3 hours.
So this is 6 to 6:19 am and there's 2 ways that you can do this actually more than 2 ways. The simplest way might just be with the number line especially "cause you're crossing, crossing this day, we're crossing 12:
00 am going into the next day. So if we think about it that way, that's my timeline, if we're starting at 11:
42 pm, it'll take us 18 minutes to get to midnight.
So that's 18 minutes to midnight, gets us to 12:00 am, and then we get another 6 hours and 19 minutes, and then we have another 6 hours, 6 hours and 19 minutes to get to when our flight lands in San Francisco, remember and this is all in eastern time.
So this is 6:19 am eastern time although we're landing in San Francisco, so we can literally just add these up, so it's going to be 6 hours, 6 hours and then 19 plus 18 is 37 minutes, 6 hours and 37 minutes. So clearly going from San Francisco to New York took less time than coming back. We probably have a head wind of some type coming back.
You could have subtracted 11:14, 11:42 from 6:19.
And you could have done it by doing something a little bit strange.
You could have said that so we are going to subtract 11:42,
let me do it, so we are going to subtract 11:42 and you want to subtract it from 6:19, but 6:19 is in the next time period.
So I want to do this it won't be military time,
"cause in military time you would just say it's 6:19am, but we're saying since we're subtracting from it something in the previous time period and the previous 12 hour period, I'm still going to add 12 hours to it. Because then we could if, if we didn't reset it two at, at,
I guess we should say 1:00 am if we didn't go from 12 to 1 and we just kept going so it became 13, uh uh 1300 hours, uh I shouldn't say that "cause that's military time, 14,15, this eventually would get to 18 instead of 6:19 am.
So this isn't military time, this is some bizarre thing that I'm just setting up just so that the math works out.
But this you could rewrite since it's in the next time period from 11:42 you could write this as 18, 18:19, and then you can subtract. So 9 minus 2 is 7, you have 1 minus 4 can't do that, borrow an hour, so you get, that becomes a 7 if you borrow an hour here you have 10 minutes here and you're going to be able to add 60 minutes to it. So that becomes a 7, 7 minus 4 is 3, and then 7 minus 1 is 6, and these cancel out.
The next case is we pick this v at random, and it just so happens that it partitions to something bigger than K--so this is case ill here.
What happens at this point? Well, all the values get separated out. all the ones smaller than v end up over here, and all the ones bigger than v end up over here. And we haven't really solved the problem yet but we have made it a lot smaller.
By picking v, we've actually just made this problem smaller. So great. Now we've handled two of the three cases.
5. - which is equal to 3, 6, 9, 12, 15.
This right here is our derivative intuition module. It was contributed by Ben Eater, and it is a pretty intresting module. What is cool about it is it really helps to conceptualize what a derivative is all about.
If you did this a little bit carelessly, you might say that the first number that goes into E is the length of the shortest hot path from A to E, which in this case would be, well there's two ways to get the distance 11 to here in two hops and then another seven. You might have said 18, but in fact, it won't expand D into E until it knows the shortest distance to D, and the shortest distance is going to be 10 because we can go this way. four plus one is five and five is 10 so it should be 17, but let's actually simulate and see what happens.
We expand out A into C and B and once we've done that, the shortest non-completed distance is the one to C so we're going to lock that down and then we expand from that node C There is two edges to incomplete nodes, C to D and C to B.
The C to B has a length of one plus length of four, we already had that actually improves this one to five and a new node joins the picture, D and C to D is seven on top of the four we already had for a total of 11. Alright, of the non-completed nodes, B and D, the one with the smallest distance is B with distance of five. We can lock that down and look at the outgoing edges from B, which is just this one that goes to D which had the length of five plus the five we already had for a length of 11 in D, which improves D, 10 and this the only node hit that we can read at this point that we haven't completed yet so we can lock it down, expand out its neighbors, which are F and E.
(Music)
Sometimes when I'm on a long plane flight, I gaze out at all those mountains and deserts and try to get my head around how vast our Earth is. And then I remember that there's an object we see every day that would literally fit one million Earths inside it.
At this point I think you know a little bit about what multiplication is. Or "multi"-plication. What we're going to do in this video is to give you just a ton of more practice, and start you on your memorization of the multiplication tables.
What's two times two?
Two times two. Well, this is equal to-- we're going to add two to itself two times. So that's two plus two.
Two times three is equal to two plus two plus two. It can also be equal to three plus three. We learned in a previous video this statement can be written either of these ways.
Two times three was that. I have that here, but now I'm just adding another two to it. So if we're too lazy to sit here and add two plus two is four.
From two to four we're going plus two. From four to six we're going plus two. And then from six to eight we're going plus two.
Two times four could've been written as four plus four as well. And what's that equal to? We could add all of these up or we could add these two up.
So two times seven.
Two times seven is equal to-- well, I could write two plus two plus two plus two-- this is getting tiring-- plus two plus two.
Is that seven? One, two, three, four, five, six, seven. And that's the same thing as seven plus seven, which you may or may not know is equal to fourteen.
So twelve plus one plus two is-- twelve plus one is thirteen.
Twelve plus two is fourteen. All right, let's just keep going.
Two times eight. I could do all of this business here where I add the twos or I could say, look, it's just going to be two more than two times seven. So I could say it's going to be fourteen plus two.
Two times nine times ten times one hundred times one thousand times one million. But I'm going to stop at twelve because that tends to be what people need to memorize. But if you really want to be a "mathelete" you want to go up to twenty.
What's two times ten? And ten times tables are interesting. And we're going to see a pattern there in a second when we try to complete an entire times tables.
Two more than two times nine. It's twenty. Or we could also say that's ten plus ten.
Ten plus itself two times. Now what's interesting about this? This looks just like a two with a zero added.
Two times eleven is going to be two more than this right here. It's going to be twenty-two. Another interesting pattern.
Two times-- that's too dark of a color.
Two times twelve.
Two times twelve is going to be two more than two times eleven. That's twenty-four. We could have also written that as twelve plus twelve.
One, two, three, four, five, six, seven, eight, nine. Actually, I'll just do it till nine. I'll just keep going.
Nine. Actually I won't have space to do that because I want you to see the entire table. So I'm just going up till nine here, but I encourage you after this video to complete it on your own.
What's one times two? That's two.
What's one times three? That's three.
One times anything is that number, so I can just write four, five, six, seven, eight, nine.
One times nine is nine. Fair enough. Now let's do the two times tables.
What's two times one? That's two. It's the same thing as one times two.
What's two times two? That's four.
Two times three is six. We just did this. Every time you increment or you multiply by a higher number, you just add by two.
Two times four is eight. Same thing as four times two.
Two times five is ten.
Two times six is twelve. I'm just adding two every time. Up here I added one from every step, here I'm adding two.
Two times seven, fourteen.
Two times eight, sixteen.
Two times nine, eighteen. All right, let's do our three times tables. I'll do it in yellow.
One times three is three. These are the same values.
Three times two is the same thing as two times three.
Three times two should be the same thing as two times three. So it's six. And that makes sense.
Three times three is nine.
Three plus three plus three. So we went from three to six to nine. So three times four is going to be twelve.
Twelve plus three is fifteen. Fifteen plus three is eighteen.
Eighteen plus three is twenty-one.
Twenty-one plus three is twenty-four.
Twenty-four plus three is twenty-seven. So three times nine is twenty-seven.
Three times eight is twenty-four. So if you were to say eight plus eight plus eight, it would be twenty-four. Let's see if I can--
Four times one is four. I'm just going to go up by increments of four. So four plus four is eight.
Eight plus four is twelve.
Twelve plus four is sixteen.
Sixteen plus four is twenty.
Twenty plus four is twenty-four.
Four times six is twenty-four.
Four times seven, twenty-eight. I'm just going up by four.
Thirty-two and thirty-six. All right, five times one.
Five times one is going to be five. Actually, we know that anything that-- well, I want us to keep changing colors, so I'll just do it in rows like this.
Five times one is five.
Five times two is ten.
Five times three is fifteen. I'm just going to increase by five.
Five times tables are very fun as well because every number you're going to add-- if we multiply five times-- well, we'll learn about even and odd in the future. But every other number in its times tables is going to end with a five, and then every other one's going to end with a zero. Because if you add five to fifteen you get twenty.
Six times one is six. That's easy. You add six to that, you get twelve.
Forty-eight plus six is fifty-four.
So six times nine is fifty-four. All right, we're almost there.
Seven times one, that's seven.
Seven times one is seven.
Seven times two is fourteen.
Seven times three, twenty-one.
Seven times four, twenty-eight.
Seven times five, what's twenty-eight plus seven? Let's see, if you add two you get to thirty. Then you add five, it's thirty-five.
Seven times six, forty-two.
Seven times seven, forty-nine.
Seven times eight-- seven times is going to be seven plus this, so it's fifty-six.
I always used to get confused between seven times eight being fifty-six and six times nine being fifty-four. So now that I pointed out to you that I always got confused between those two, it's your job not to be confused by those two.
Seven times eight you could say has the six in it.
Six times nine doesn't have the six in it. That's the way I think of it. Anyway, seven times nine.
Eight times one is eight.
Eight times two is sixteen.
Twenty-four.
Eight times three is twenty-four. And if we go to three times eight we should also see the twenty-four. Yep, it's there.
Let's see, eight times four, you're going to add eight to it-- thirty-two.
Forty. Add another eight, forty-eight. Notice, eight times six, forty-eight.
Six times eight, forty-eight. All right, eight times seven. Well, we already pointed that one out, that was fifty-six.
Eight times eight, sixty-four.
Eight times nine, add eight to this, is seventy-two. Now we're at the nine times tables. I'm running out of colors.
Nine times one is nine.
Nine times two, eighteen nine times three-- we actually know all of these. We could look it up in the rest of the table because nine times three is the same thing as three times nine. It's twenty-seven.
Twenty-seven plus nine is thirty-six.
Thirty-six plus nine is forty-five. Notice, every time you add nine, you go almost up by ten, but one less than that. So up by ten would be forty-six, and then one less than that is forty-five.
Nine times seven, sixty-three.
Nine times eight, seventy-two.
Nine times nine is eighty-one. I don't know if you can see that.
Eighty-one. There you go. Now, I could keep going.
JOHN BOEHNER: Members of Congress, I have the high privilege and distinct honor of presenting to you, the President of the United States. (Applause.)
Twelve years ago, I was in the street writing my name to say, "I exist." Then I went to taking photos of people to paste them on the street to say, "They exist." From the suburbs of Paris to the wall of Israel and Palestine, the rooftops of Kenya to the favelas of Rio, paper and glue -- as easy as that.
Well let me tell you, in terms of changing the world there has been a lot of competition this year, because the Arab Spring is still spreading, the Eurozone has collapsed ... what else? The Occupy movement found a voice, and I still have to speak English constantly. So there has been a lot of change.
Slim and his friends went through the country and pasted hundreds of photos everywhere to show the diversity in the country. They really make Inside Out their own project. Actually, that photo was pasted in a police station, and what you see on the ground are ID cards of all the photos of people being tracked by the police.
Juarez: You've heard of the border -- one of the most dangerous borders in the world. Monica has taken thousands of portraits with a group of photographers and covered the entire border.
Abololo -- of course a nickname -- has pasted one single face of a woman to show his resistance against the government. I don't have to explain to you what kind of risk he took for that action. There are tons of school projects.

Our next guest is Andrew Goldberg. He's a principal researcher at Microsoft Research, Silicon Valley, and his work focuses on creating algorithms for real-world problems. One of the interesting problems he's studied is how to find the shortest path in really, really large networks in microseconds, so he's going to tell us a little bit about algorithms for doing that.
[Andrew Goldberg] Recently I've been working a lot on shortest path algorithms, especially motivated by GPS navigation applications, so basically how to get from A to B.
Out of how many million did you say? 16 million?
18.>>[Male] 18 million.
You only need 70. It's very, very fast. If you think about that if you sort these hubs by node ID we have 2 arrays, and you just need to intersect these 2 arrays of size 70, which you can do like a merge sort that is very good locality.
Welcome back. I'm now going to introduce you to a new tool for solving derivatives. Really between this rule, which is the product rule, and the chain rule and just knowing a lot of function derivatives, you'll be ready to tackle almost any derivative problem.
20x to the eighth minus 7. And I add that to the derivative of this second expression, this is all on one line but I ran out of space, 160x to the seventh, right?
8 times 20 is 160. And then the derivative of 7 is zero. So it's just 160x to the seventh times this first expression.
Here I'm going to use a slightly different notation. Instead of saying f of x and then what's f prime of x, I'm going to say y is equal to x squared plus 2x to the fifth times 3x to the minus three plus x squared to the minus 7. And I want to find the rate at which y changes relative to x.
Now, the last piece in understanding customer segments is understanding their pains. We've been talking about all the wonderful stuff that we do for them that makes them happy. What are the things that we could get rid of that actually is kind of like they've been walking around with an arrow through their head, and they've just kind of accepted that for a while, but when you come about you could say, "Hey, we could solve these problems for you?"
"Yes, the customer said this was a real pain." "Our product really solves these problems." Well, one of the things you need to know is was this like problem #47 on their list?
"Is there any way that our product or service could actually solve anything in the top 5?" And if not, maybe you're in the wrong customer segment, and so you want to understand what's keeping your customer awake at night? Or maybe conversely, maybe you want to keep them awake at night, but you want to figure out what are their big issues, concerns, and worries?
Let's take a look at some value proposition examples. I've selected some to just give you an idea of how other startups have approached articulating their value proposition. Here was a company that was actually trying to develop a bio-based replacement for surfactants.
Welcome back. On the last video we came to the conclusion that we could figure out the volume when we rotate a function about the x-axis, so let's apply that to an actual exercise. I'm going to erase everything because I don't want you to memorize this, because frankly I haven't memorized this.
Maybe you want to memorize it if your teacher tends to give you a test that don't have much extra time in them, just to speed up the process. But you should know what's going on. So let me draw the axes again.
Pi is just a constant and the antiderivative of x is x to the 1/2 over-- I'm sorry.
I've been a little rusty since I last did some antiderivatives. So we get x squared, we get pi times x squared over 2.
That's the antiderivative of that. And then we have to evaluate it at 1 and then subtract it and evaluate it at 0. And so what do we have.
Well, what's the probability of randomly selecting a sample of size 20 and getting a mean of at least 8.94 for engagement, and 8.35 for a learning?
So, the interesting thing about this problem is you have a choice. Depending on whether you add c or e to the open list first and the first step. So, you take d out the open list, you add c and e, or you add e and c.
It is a dream of mankind to fly like a bird. Birds are very agile. They fly, not with rotating components, so they fly only by flapping their wings.
(Laughter) And this was one issue: to build it that lightweight that no one would be hurt if it fell down. So why do we do all this?
(Applause)
(Cheers) (Applause) (Applause ends)
(Applause) So we can now look at the SmartBird. So here is one without a skin.
And if we now beat up and down -- (Mechanical sounds) We have the possibility to fly like a bird. So if you go down, you have the large area of propulsion, and if you go up, the wings are not that large, and it is easier to get up.
Thank you. (Applause) Bruno Giussani:
(Audience) Yeah! (Laughter)
(Gasps)
(Cheers) (Applause)
Hi. I'm here to talk to you about the importance of praise, admiration and thank you, and having it be specific and genuine. And the way I got interested in this was,
"Thank you for being the breadwinner, so I can stay home with the kids," but won't ask. I know a woman who's good at this. She, once a week, meets with her husband and says,
"I'd really like you to thank me for all these things I did in the house and with the kids." And he goes, "Oh, this is great, this is great." And praise really does have to be genuine, but she takes responsibility for that.
"Would you praise me this way?" And it's because I'm giving you critical data about me. I'm telling you where I'm insecure.
Let's say that Arman today is 18 years old And let's say that Diya today, is 2 years old And what I am curious about in this video, is how many years will it take
How many years, will it take for Arman to be 3 times as old as Diya? So that's the question right there And I encourage you to try to take a shot at this yourself
How many years will it take for Arman to be 3 times as old as Diya? So let's set some variable, let's say y will be years Let's say y is equal to years it will take
Now we'd like you to write this flip book animation style in code. We've given you a list of image assets to use for "Evil Devices". What you need to do is load all of these image assets and place them in the frame array.
So now that we will update channel economics for direct sales, let's go take a look at what the channel economics would look like if we were selling through an indirect channel, resellers. So as you could see, we still have the same cost of goods to manufacture the product as before, $33.
What I want to do in this video is how supply and / or demand might change based on changes on some factors of the market and then think about what that might do to the equilibrium price and equilibrium quantity. So let's say at some period, this is what the supply curve looks like, and this is what the demand looks like and then all of a sudden this thing happens. A new disease resistant apple is invented what's likely to happen for the next period?
I'm now going to show you what I think are probably the two coolest derivatives in all of calculus. And I'll reserve that. None of the other ones have occurred to me right now.
I think I'm going to need a lot of space for this. I'm going to try to do it as neatly as possible. So the derivative of the natural log of x equals-- well
And so that equals the limit as delta x approaches 0-- I think it's time to switch colors again-- delta x approaches 0 of-- well let me just write this 1 over delta x out in front. So this is 1 over delta x, and we're going to take the limit of everything.
ln x divided by x is 1 plus delta x over x. Fair enough. Now I'm going to throw out another logarithm property, and hopefully you remember that-- and let me put the properties separate so you know it's not part of the proof-- that a log b is equal to log of b to the a.
Remember we're taking the natural log of everything. And we know this is an exponent property, which I'll now do in a different color. We know that a to the bc is equal to a to the b to the c power.
1/u, and then all of that to the 1/x. And how did I do that? Just from this exponent property, right?
So this whole thing is equivalent to 1/x times the natural log, and this we know, this is one of the ways to get to e. So the limit as u approaches 0 of 1 plus u to the 1/u. That is e.
The first months of 2007 passed by with an intense preparation. And Engin Akyurek got on the stage with Romantika Musical premiered on March 30. This time he was Çeto (Cheto), the smart guy in a Roman neighborhood.
- Do you want something to eat, Halim? - No, no. I am not hungry and I am on duty now.
[Anyways, they've left.]
And he tells "You need to stroll around there, you need to stop by one of the coffee shops".
[Thank God!]
[I will got to sleep now.]
In short, he first knows the character he will play...
Here's a sketch of the algorithm as we were just running it by hand. Largely, we're trying to find shortest distances from D to the other nodes in the graph. we initialize D's distance to V as 0, then we imagine that all the other distances to all the other nodes in the graph were as yet unknown, and each time we go through the loop, that there's still nodes left that haven't been completed yet. We find the node with the shortest known distance and then we locked it down.
We are losing our listening. We spend roughly 60 percent of our communication time listening, but we're not very good at it. We retain just 25 percent of what we hear.
Secondly, the world is now so noisy, (Noise) with this cacophony going on visually and auditorily, it's just hard to listen; it's tiring to listen. Many people take refuge in headphones, but they turn big, public spaces like this, shared soundscapes, into millions of tiny, little personal sound bubbles. In this scenario, nobody's listening to anybody.
(Audience: Yes.) Good. The first one is silence.
And RASA stands for Receive, which means pay attention to the person; Appreciate, making little noises like "hmm," "oh," "okay";
So, how does it work for startup weekend next. Well, after the weekend, it seems that you're told that you're going to be presenting your results tomorrow and the types of things we want to see is how big is this idea. So, you have to understand that this is a note for the facilitators and coaches
I'm speaking about compassion from an Islamic point of view, and perhaps my faith is not very well thought of as being one that is grounded in compassion. The truth of the matter is otherwise. Our holy book, the Koran, consists of 114 chapters, and each chapter begins with what we call the basmala, the saying of "In the name of God, the all compassionate, the all merciful," or, as Sir Richard Burton -- not the Richard Burton who was married to Elizabeth Taylor, but the Sir Richard Burton who lived a century before that and who was a worldwide traveler and translator of many works of literature -- translates it.
"Adorn yourselves with the attributes of God." And because God Himself said that the primary attribute of his is compassion -- in fact, the Koran says that "God decreed upon himself compassion," or, "reigned himself in by compassion" -- therefore, our objective and our mission must be to be sources of compassion, activators of compassion, actors of compassion and speakers of compassion and doers of compassion. That is all well and good, but where do we go wrong, and what is the source of the lack of compassion in the world?
"Come in, for there is no room in this house for two I's," -- two capital I's, not these eyes -- "for two egos." And Rumi's stories are metaphors for the spiritual path.
(Applause)
I'm going to start on a slightly somber note. Two thousand and seven, five years ago, my wife gets diagnosed with breast cancer. Stage IlB.
Anyone in the audience want to take a stab? Audience member: Pulpit!

I could draw 16 apples and then take away 4 of the apples.
Or I could actually draw a number line, and actually let me do it here just to start off the video to get warmed up.
I could draw the number line and maybe that's 16 maybe that's 17. It's 15, 14, 13, 12, let me go down all the way to 11. I could keep going but I've run out of space.
16 - 1 is 15, minus 2 is 14, minus 3 is 13, minus 4 is 12. And you would have the answer.
16 - 4 is 12. Now an even easier way to do this problem is just to focus on the places of the digits. Now let me be clear what I mean when I say that.
16 - 4, and I've gone over this a little bit in the addition videos. This is the ones place.
The 6 is in the ones place.
The 4 is in the ones place.
The 1, right here, this right here, or there was something down here, this column, that is the tens place. Now what do we mean by that?
Well 16 is the same thing as 10 + 6. So when we write it, this 1 literally means one 10. If you think of it in money it means one $10 bill.
You can actually just look at just the ones place and think about 6 - 4, and say 6 - 4 well you could draw a number line or you could even use your fingers if you have to, but you probably have that memorized. You could probably visualize it in your head, 6 - 4 is 2. And then 1, then we go to the tens place, 1 minus nothing -- there's nothing over here.
8 - 7 is equal to 1.
7 - 3 -- now remember, this is seven 10s, or seven $10 bills, minus three $10 bills. If I had seven $10 bills and I give away three of those $10 bills, then I'll have four $10 bills, or 7 - 3 is equal to 4. And just like that we were able to figure out that 78 - 37 is 41.
9 - 3 is 6.
95 - 31 is 64. You're probably saying, Sal, subtraction is easy. I can just look at each place, the ones place and subtract, tens places and subtract.
But we know that 17 is smaller than 22. So what can we do here to actually do this subtraction problem? So what we do here, and you might call it borrowing, you might call it regrouping.
The 17 is 10 + 7. That's just another way to write 17. Now we have a 2 here.
We went from two $10s to one $10 and it became just one $10 bill. Then I gave that 1 to this 2. This 2 then becomes a 12.
12 - 7 -- I'm just doing the same problem -- just written slightly different on this right hand side -- is also 5.
Then we have 1 - 1 is 0. I could write this as 05, but that's just the same thing as 5. And here I'd have 10 - 10.
-- or sorry, I can give $90 to this guy right here, and then I can give $1 to this guy -- sorry, I could give $99. sorry -- I could give $90 to this guy and then I can give $10 to that guy right there.
And just like that, all my numbers in each column, if I were to draw columns like this, divide them up. Everything on top is bigger than everything on the bottom so now I can subtract.
So 13 - 7 is 6.
9 - 6 is 3.
6 minus nothing is 6. So 703 - 67 is 636. Now you might be saying,
-- I'll do the same problem over again 703 - 67. I look at all of the numbers on the top and I say are they all larger than the numbers on the bottom? I said well, 3 -- well, 7 is larger than 3, that's not good.
6 is larger than 0, that's not good. So I need to do something. So what I do is I start with this 3 right here, and I say well, can I borrow from this number to the left?
So then I look to the two numbers to the left and say can I borrow from 70? I say well gee, I can definitely borrow from 70 we know this is actually 700. So if I borrow from 70 what happens?
703 - 67. You could start at the left. You could say look, 7 is, well, it's larger than what's below it.
And you say well, 0 -- well, 0 is not bigger than what's below it. it's not bigger than the 6 below it. So I'm going to need to borrow.
3 is smaller than 7. Still not cool. I won't be able to subtract, so let me borrow again.
Remember, it's not a 1. I added 10 to it. If I take 1 from the ten's place, that's like adding 10 to the ones place.
So 13 - 7 is 6, 9 - 6 is 3, 6 - 0 is 6.
636. Let's do a couple more problems, because the subtraction sometimes with the borrowing can become a little bit confusing on what to do next. Let's say 953 - 754.
So if I borrow from the 5, the 5 will become a 4, and I'd borrowed 1, the 3 becomes a 13.
Remember, if I borrow 1 from the tens place, that's actually a 10. This is 5 tens. I took one of the 10s away, so I'm left with four 10s, and I added that 10 to the 3, so I have 13.
13 - 4, I'll be able to subtract there. But here I have a problem.
4 is less than 5.
So I'm going to have to borrow again. I'm going to say well, let me take a 1 from the 100s place, so that will become an 8. And let me give that 100 to my tens place.
I took the 1 from there and I borrowed it, or I rearranged that 100. I could re-write that 100 as one 10, and so that's what got us to that from 9 to 8
I took away 100 from the 900 to get 800. And when I re-wrote the 100 in the tens place, it's ten 10s.
So that's why I added a 10 to the 4 that I had before. I could have just scratched it out and put the 14 like that to show that I had to re-write the 4. But now all of a sudden I'm cool.
13 - 4 is 9.
14 - 5 is 9.
8 - 7 is 1.
953 - 754 is 199. Now let's do it the left to right way.
953 -- let me use a different color -- minus 754. Now this is will be a little bit different than I did last time. I say well 9 is definitely larger than 7.
5 is definitely larger -- well, at least it's equal to 5, so if I subtract maybe I'll get a 0 there. And 3 is less than 4. So maybe I'll just have to borrow here.
So maybe we'll just throw that 100 right here. So if we throw the 100 into the ten's place, it's ten 10s. So the 5 becomes 15.
14 - 5 is 9.
8 - 7 is 1. Hopefully you found that pretty straightforward. These are, frankly, as hard as the borrowing problems get.
If you ever get really confused about it, you should always go back to this. You should always go back to this notion of regrouping. This notion of OK, if these things are all too small,
And let me regroup that $100 bills into the other spaces. In this case, we took the $100 bill and we put 90 here or nine 10s, nine $10 bills, and then $10 of it right there to make everything in the numerator
I'm Jessi, and this is my suitcase. But before I show you what I've got inside, I'm going to make a very public confession, and that is,
I want to get back to my suitcase and tell you what I packed for this exciting week here at TED. I mean, what does somebody with all these outfits bring with her? So I'm going to show you exactly what I brought.
(Applause) So as I do this, I'm also going to tell you a few of the life lessons that, believe it or not, I have picked up in these adventures wearing nothing new.
Basically, there's a major demographic event going on. And it may be that passing the 50 percent urban point is an economic tipping point. So the world now is a map of connectivity.
The question is, why? And here's the unromantic truth -- and the city air makes you free, they said in Renaissance Germany. So some people go to places
One-sixth of humanity is there. It's soon going to be more than that. So here's the first punch line: cities have defused the population bomb.
Stars have shined down on earth's life for billions of years. Now we're shining right back up.
Thank you.
Here's a little bit of code for computing the clustering coefficient-- at least one particular way of computing it. Here's our list of flights on our map. Catching between Chicago and Seattle, etc., and I just have that as a list of pairs.
So if you're a facilitator or a teacher, what is it you're doing? You should understand this is an adapted version of the Lean LaunchPad curriculum that is actually for post-Startup Weekend events. That is, it comes after students actually sit through a Startup Weekend and kind of raise their hands and say, "Hey, we'd actually like to learn more."
"and actually figure out whether we could put together a startup." This is not a full semester class and not the full version of the Lean LaunchPad, but these teams will learn a tremendous amount in the weeks that they will be spending with you. This helps fill a gap between the Startup Weekend and the next step that most entrepreneurs think they should take, which is commonly seen as an accelerator.
What is the cost of 14.6 gallons of gasoline at $2.70 per gallon? So we have 14.6 gallons, and each gallon's going to cost $2.70. Or we can even view $2.70 as 2.7 dollars.
7 times 6 is 42. Regroup the 4. 7 times 4 is 28, plus 4 is 32.
7 times 1 is 7, plus 3 is 10. So we get 7 times 146 is 1,022. Now we're going to deal with this 2.
2 times 6 is 12.
Carry the 1, or regroup the 1. We can ignore these guys right now.
2 times 4 is 8, plus 1 is 9.
2 times 1 is 2, and now we can add.
2 plus 2 is 4.
0 plus 9 is 9.
1 plus 2 is 3. Now we've figured out what 146 times 27 is. It's 3,942.
This is a pretty straightforward thing to write in Python. Let's imagine that we've got a list L--I made a list which is the node centrality values from one of the recent graph that I used as an example. And we're going to define a subroutine mean that takes a list and initializes total to 0, runs through all the elements in the list adding up their values, and then returning the total divided by the length.
Can you give me a hint about why Microsoft cares about any of this? Well, Bing Maps is an obvious example. Bing Maps computes driving directions.
Hello, I'm now going to do some practice least common multiple problems for you. After I do a couple of these problems you should be able to go to the least common multiple module and do some of them yourselves. Let's say the least common multiple of 10 and 8.
10 times 2 is 20.
30, 40, 50, 60, whoops. Not 67. 70, 80, 90, 100 and so on.
Multiples of 8 are 8, 16, 24, 32, 40, 48, 64, 72, 80 and so on. So let's see. Let's see if we can identify what the common multiples are.
8 times 10 and then you divide that by the greatest common factor of 8 and 10. Well, 8 times 10 is 80, and the greatest common factor of 8 and 10? Well, we just figured that out.
Another way to build a heap out of a set of values is insert the items one at a time into the heap. Here is one way to implement this. We want to know what is the running time of this code.
Imagine a big explosion as you climb through 3,000 ft. Imagine a plane full of smoke. Imagine an engine going clack, clack, clack.
I came up with a saying, which is, "I collect bad wines." Because if the wine is ready and the person is there, I'm opening it. I no longer want to postpone anything in life.
What I'm going to show you first, as quickly as I can, is some foundational work, some new technology that we brought to Microsoft as part of an acquisition almost exactly a year ago. This is Seadragon, and it's an environment in which you can either locally or remotely interact with vast amounts of visual data. We're looking at many, many gigabytes of digital photos here and kind of seamlessly and continuously zooming in, panning through it, rearranging it in any way we want.
(Applause) (Applause ends) You know, I never thought that I'd end up working at Microsoft.
What the point here really is is that we can do things with the social environment. This is now taking data from everybody -- from the entire collective memory, visually, of what the Earth looks like -- and link all of that together. Those photos become linked, and they make something emergent that's greater than the sum of the parts.
>> For a game developer, tools are the life force of your development cycle. It's starts all the way at the beginning with the compiler that the programmers use, all the way to the art creation tools for the artists and even notepad and text editors for the designers. Basically, it's how we get things done.
You'll actually find that HTML 5 and JavaScript, in particular, is very capable of reading in data formats from all these tool systems. So, go out and educate yourself before you throw your money away, you'll find some good stuff out there.
What to do with your Fresh Raspberries Here is a great Recipe for a No-Bake Raspberry Icebox Cake I picked my fresh Raspberries at Franklin Farms in Clarksburg, WV 2 pounds fresh raspberries
Ingredients: 2 pounds fresh raspberries 3 1/4 cups whipping cream 1/3 cup sugar 1 teaspoon vanilla 1 teaspoon fresh lemon zest 1/8 teaspoon salt 28 honey graham crackers
Alright. So really, all you have to do is set ChainGun equal to Weapon.extend and in this case, we're not extending it with any further functionality. We'll be getting to that later.
I commented that it's unfortunate that Abraham Lincoln is assassinated shortly before the end of the Civil War.
And, although that is technically correct, what I want to do is clarify that comment a little bit in this video. Because, in actuality, by the time he was assassinated, Lincoln knew that the Union was very, very, very
likely to win the war -- that the major Confederate armies had already surrendered to the Union.
So, if we go back to April 9th, 1865, you have the battle at Appomattox Courthouse; and after that battle, the Confederate Army is essentially routed.
And on April 9th, 1865, after that battle, he surrenders to Ulysses S. Grant.
And one point of confusion some people often have -- and I had this the first time I learned it -- is that "Appomattox Courthouse" is the name of the city; the surrender actually did not take place in the courthouse in that city.
And I'm showing his image because his set of circumstances, or how he is tied to the Civil War, is frankly fascinating, because in 1861, the first battle of the Civil War occurred on his property in Manassas, Virginia. This is in Northern Virginia. He was sympathetic with the Confederate army.
Hi everyone. I'm an artist and a dad -- second time around. Thank you.
Another thing to think about is what's the market size estimate? How big is this and what's the percentage marketshare realistically you could get? How many can you distribution channel actually sell?
And so the phases of customer discovery start with stating your hypotheses, testing the problem, testing the solution, or verifying or pivoting.
What I wanted to talk to you about today is two things: one, the rise of a culture of availability; and two, a request. So we're seeing a rise of this availability being driven by mobile device proliferation, globally, across all social strata. We're seeing, along with that proliferation of mobile devices, an expectation of availability.
"The stretch." OK, the gentleman on the left is saying, "Screw you, I'm going to check my device."
"You are not as important as, literally, almost anything that could come to me through this device." Look around you. There might be somebody on one right now, participating in multi-dimensional engagement.
Let's take a look at the types of intellectual property. What I'd like you to do is help me understand if we look at the column on the left, trademark, copyright, trade secrets, contracts and NDA, and patent, and match up what's in the protectable column and the example columns to the correct type of intellectual property.
Now that we've got the basics of order of operations out of the way, let's try to tackle a really hairy and beastly problem. So here, we have all sorts of parentheses and numbers flying around. But in any of these order of operations problems, you really just have to take a deep breath and remember, we're going to do parentheses first.
Well, if we look at just inside of it, the first thing we want to do is simplify the parentheses inside the parentheses. So you see this 5 minus 2 right there? We're going to do that first no matter what.
And so this simplifies to-- I'll do it step by step. Once you get the hang of it, you can do multiple steps at once. So this is going to be 7 plus 3 times the 5 minus 2, which is 3.
7 plus 9 is 16. And so everything we have simplifies to 7 times 2 plus 16 divided by 4 times 2.
Now we don't have any parentheses left, so we don't have to worry about the P in PEMDAS. We have no E, no exponents in this. So then we go straight to multiplication and division.
That gets priority of the addition, so we're going to do that before we do the addition. But how do we evaluate that? Do we do the division first, or the multiplication first?
For this question, I want you to draw a planar graph with 8 nodes and then connect those 8 nodes with 15 different edges, and the question is how many regions does the graph have?
 We will now begin our journey into the world of statistics, which is really a way to understand or get our head around data. So statistics is all about data.
looking at your plants, just said, well, you know, how tall are your plants? And they only want to hear one number. They want to somehow have one number that represents all of these different heights of plants.
And this is really just the sum of all the numbers divided by-- this is a human-constructed definition that we've found useful-- the sum of all these numbers divided by the number of numbers we have. So given that, what is the arithmetic mean of this data set? Well, let's just compute it.
15 plus 7 is 22. Let me do that one more time. You have 7, 8, 14, 15, 22, all of that over 6.
I think what is probably the most misunderstood concept in all of science and, as we all know, is now turning into one of the most contentious concepts - may be not in science, but in our popular culture - is the idea of evolution. Evolution. And whenever we hear this word - I mean: even if we don't hear in in the biological context -, we imagine that something is changing, it is evolving, and so when people use the word evolution in its everyday context, they think of this notion of change that, you know, - this is going to test my drawing ability - , but they, you know:
- well, I'm doing my best - that's the ape, and may be is also wearing a hat and then they show this picture where he slowly slowly becomes more and more upright and eventually he turns into some dude who is just walking on his way to work, also just as happy. And now he is walking completely upright and - you know - there is some kind of implication that walking upright is better than not walking upright, and - oh he doesn't have a tail anymore. Let me eliminate that.
The DNA didn't say: Hey, it is better to be walking than to be kind of hunched back like an ape and you know therefore I'm going to try to somehow spontaneously change into this dude.
Antibiotics. They attack bacteria, they kill them. Now you've probably, if you know a couple of doctors or whatever, and you say:
On August 5th, 1857, a 4,300 km long cable was laid across the Atlantic Ocean, it provided a link between Britain and the Americas, further strengthening their social and economic alliances. Now information could be represented as a pattern of electrical pulses, and sent across the world almost instantaneously. Stock tickers, and money transfers, these were commercial applications invented by Western Union which ushered in a new era of global communication.
The Bombe was multiple Enigma rotors chained together, allowing it to rapidly test different key settings. It took advantage of the fact that common words were known to be in the original message, such as weather, and these came to be known as crypts.
For a given messaging crypt, the Bombe could scan through all possible rotor positions and orders, in order to find possible key settings in a matter of minutes. This machine allowed the allies to read German commands within hours of them being issued. It was a fatal blow to their combat strategy, as the allies could anticipate their next move.
This would have prevented the reverse engineering of the rotor wirings, and if the Enigma allows the letters to be encrypted to themselves, the Bombe couldn't have taken advantage of crypts, and this would require the allies to check the entire key space, which was impossible even with the fastest computer. Repetition reduced the key space. Otherwise the outcome of World War II could have been drastically different.
Duncan Watts is one of the world experts in analyzing social networks and learning about what's going on inside of that. He has been a professor at Columbia University and also a network scientist at Yahoo
Microsoft Research in New York City. We weren't able to get video footage of our conversation together but I think you'll find it interesting anyway. What are some of the factors that have contributed to the explosion of interest in social network analysis?
MapReduce, right.
So I think that if you want to work with very large scale network data then some familiarity with the MapReduce framework and whichever implementation I guess on these days is going to be extremely valuable and there's been some interesting theoretical work showing how algorithms like breadth first search can be converted into a
MapReduce parallel framework and that's actually generated a great deal of recent progress. Can you tell us a little bit about the idea of community detection? You want to assign everybody in the network to a community such that the communities you choose have the property that most of the links are within the communities not across the communities, one of the methods that was developed Jack Hoffman at
Microsoft but when he was at Columbia, he where you are starting with a network and you are assigning - you start to some sort of prior assumption about how many communities around the network and then you sort of make a guess about who goes into which community and then you measure the relative densities of internal versus external links and then you shuffle back and forth making various random changes, so try to optimize the allocation of people to communities in order to get this sort of maximization of modularity.
Hi, my name is Jeff Law and I'm from Haas Automation I'm here today to talk about advanced tool management With most machine tools, defining, calling, and managing backup tooling is complicated and time consuming
To make it easy to remember I'm going to call this group 1023 1023 Use the arrow keys to highlight "Add" and press [WRlTE / ENTER] Now I've added group 1023
"23" [WRlTE / ENTER] Now I can arrow down and define back-ups Tool 31 is my first back-up tool
"31" [WRlTE / ENTER] And 32 is the second back-up tool
"32," [WRlTE / ENTER] Now that I've defined my group, it's time to incorporate this group into my CNC program In a standard CNC program
With the advanced editor functions in the Haas control, this couldn't be easier I go to "Edit" mode, press [F1] This brings up a series of menus where I can select "Find and Replace Text"
Replace with "T1023" [WRlTE / ENTER]
[F] to replace forward And [A] to replace all I've just replaced all my T23s with T1023
G43 H23 gets replaced with G43 H1023 And if I'm using cutter comp, I'll do the same for the diameter calls, G41 D1023 And now as I run this program over and over
Unit 5 combines ideas from graph search that we studied in Unit 3 with ideas about computing statistic that we look at in Unit 4 and it puts these tools together to give us the way of finding shortest path in these networks. Social networks come in many different flavors. Some of them consist of simple yes/no connections between the individuals in the network but others include more detailed information about the strength of those connections.
I grew up in New York City, between Harlem and the Bronx.
Growing up as a boy, we were taught that men had to be tough, had to be strong, had to be courageous, dominating -- no pain, no emotions, with the exception of anger -- and definitely no fear; that men are in charge, which means women are not; that men lead, and you should just follow and do what we say; that men are superior; women are inferior; that men are strong; women are weak; that women are of less value, property of men, and objects, particularly sexual objects. I've later come to know that to be the collective socialization of men, better known as the "man box." See this man box has in it all the ingredients of how we define what it means to be a man.
"Just go in your room. Just go on, go on in your room. Sit down, get yourself together and come back and talk to me when you can talk to me like a --" what?
(Audience: Man.) Like a man.
"My God, what's wrong with me? What am I doing? Why would I do this?"
"How would you feel if, in front of all the players, your coach told you you were playing like a girl?" Now I expected him to say something like, I'd be sad; I'd be mad; I'd be angry, or something like that.
"It would destroy me." And I said to myself,
"God, if it would destroy him to be called a girl, what are we then teaching him about girls?"
(Applause) It took me back to a time when I was about 12 years old. I grew up in tenement buildings in the inner city.
"What is this 16-year-old boy doing with these 12-year-old boys?" And he did spend a lot of time up to no good. He was a troubled kid.
"Hey Anthony, come on upstairs." Johnny call, you go. So I run right upstairs.
"Do you want some?" meant one of two things: sex or drugs -- and we weren't doing drugs. Now my box, my card, my man box card, was immediately in jeopardy. Two things:
"What would life be like for you, if you didn't have to adhere to this man box?" He said to me, "I would be free." Thank you folks.
Let's see if we can figure out 3 times 60. Well, there's a couple of ways you could think about it. You could literally view this as 60 three times, so you could view this as 60 plus 60 plus 60.
50 plus 50 plus 50 plus 50 (let's see... that's four) plus 50 plus 50 (let's see... that is 6, I'll do one more right over here) plus 50. So this is 50 seven times. 50 plus 50 is 100, 150, 200, 250, 300, 350.
In the beginning the web was simple, connected open, safe designed as a force for good it would become something far greater a living, breathing ecosystem in service of humanity a public resource for innovation and opportunity.
Join us - we need your support.
So world-class entrepreneurs are never lucky. Never. You make your own luck.
Tangible problems. I always felt from as long as I can remember about the power of science, that it could be used to solve pressing issues, solve problems. When I studied Chemistry at Princeton it was so theoretical, unapplied.
The Powercube right now works with both the Lifetrac and the CEB Press, and a few other machines we have, like the Ironworker and the Coldsaw. So that provides a much simpler product ecology because one power unit serves multiple machines. There is one thing about just being able to look at machines that have been developed on site here, and another thing to understand how the development process went through and what kind of documentation there is for these machines, such that can be replicated and improved on.
A film by Tristan Copley Smith
Motor racing is a funny old business. We make a new car every year, and then we spend the rest of the season trying to understand what it is we've built to make it better, to make it faster. And then the next year, we start again.
(Applause)
This video details the Installation Procedure for Haas Turning Centers Here an ST-30SSY is being installed Start by walking around the Machine and checking for any shipping or rigging damage
For DS models, detach the Security Bracket connecting the Second Spindle to the Machine Base
Using WD-40 or another PH-Neutral Degreaser spray all Waycovers and other surfaces that have been coated with Cosmoline
letting the WD-40 soak in while other tasks are completed This will make the Cosmoline removal easy
The Axes should not be moved until all the Cosmoline has been removed Unwrap the Foot Pedals, unwind the Cord and attach the cord behind the Removable Cover Next, install the Air Gun at the front panel Air Fitting, just below the Control
Move to the T5 Transformer and set the Shorting Plug to the range that matches the Transformer Tap position just used Now, switch on the Machine's primary Breaker and move to the Control Panel and press POWER ON At the back of the Machine, check that the wiring from the customer's Service Panel is in Phase with the connections at the Machine by checking that the Phase Indicating Light is lit green
Enter the "Key Code" and press WRlTE The Machine will now function normally
With the Cosmoline softened by the WD-40 it can now be removed using Shop Towels A Plastic Scraper or Squeegee can be used to remove very thick applications of Cosmoline Do not use Scotchbrite or other Metal Scrapers as these will scratch the Waycovers
Remove all signs of Cosmoline and WD-40, leaving the Machine clean with nothing remaining to contaminate the customer's Coolant At the Control Pendant, press "ZERO RETURN" and then "ALL" The Axes will move to their Home positions
The "Zero All Axes" option is not available on DS-30 Machines in order to decrease the chances of crashing Axes which are close together and holding complex tooling For DS-30 Machines, you will need to Zero each Axis individually after Starting-Up The Machine is now ready for Leveling, which will achieve three objectives
Visit Haascnc.com to find the video that examines the leveling process in detail Remove the Protective Film from the Windows, the Monitor, and the door handle Ask someone to assist you to hold the weight of the Chip Conveyor while you unfasten the Shipping Security Screws and lower the Conveyor into position
Connect the Electrical Cable to the receptacle labeled "Conveyor" Route the Electrical Cable neatly from the Conveyor Motor down to the receptacle Take up any slack in the Cable and Zip Tie it near the Receptacle
Attach the Clamping Band outside the Chip Skirt and fashion at the Discharge Port Attach the Upper Access Panel Now is a good time to install the Coolant Tank and its related components
The Installation Procedure for mounting the HlL lights and connecting them electrically is also available online The remaining Options installed on this machine such as Automatic Tool Presetter and Programmable Tailstock are ready to go when the Machine is energized This Lathe is fully functional and installation is complete
What I want to do in this video is think about the demand curve for two different products. So this is some laptop that's on the market. And this, let's just say, is the cheapest car that happens to be on the market this is actually a picture of a 1985 assuming this is the cheapest car on the market.
I told you three things last year. I told you that the statistics of the world have not been made properly available. Because of that, we still have the old mindset of developing in industrialized countries, which is wrong.
(Applause) And if I could share the image with you on the screen. So three things have happened.
And this is GDP per capita on this axis. And this was 2007. And if I go back in time, I've added some historical statistics -- here we go, here we go, here we go -- not so much statistics 100 years ago.
"Well, you were the one who caused the problem." The OECD countries -- the high-income countries -- they were the ones who caused the climate change.
"But we forgive you, because you didn't know it. But from now on, we count per capita. From now on we count per capita.
(Laughter) Homage to the Office package, no?
What is this, what is this, what am I telling? I'm telling you that there are many dimensions of development. Everyone wants your pet thing.
Sword swallowing is from ancient India. It's a cultural expression that for thousands of years has inspired human beings to think beyond the obvious. (Laughter)
(Applause)
What can happen to a startup? Well, the best thing that could happen to a startup is that it can grow into a company and hopefully a large company after you found a repeatable and scalable business model. Or 2 is well you can still pivoting and iterating as you continue to search for a business model.
We're looking at the same basic setup as the last time. We're making a graph with n nodes, and again we're going to assume n is some power of 2. If it's just a single node, we just return that node.
A graph with n nodes has however many edges are in 2 subgraphs, each of size n/2. Then we are going to add to that--what? We're going to take n/4 of the set of nodes and fully connect them with another set of n/4 nodes. n/4 from one side, n/4 from the other.
Thinking about the 2 x 2 matrix on the last slide, a real question for you is-- how does your product get to the customer? I think the real questions start with what type of product do I have. Do I have a product made out of bits that is--is it virtual or is my product a physical product.
My goal in this video and the next video is to start giving a sense of the scale of (really, just) the Earth and the solar system, and as we see as we start getting into (like) the galaxy and the universe it just becomes almost impossible to imagine but we'll at least give our best shot. So I think most of us watching this video know that this right here is Earth. This right here is Earth.
It goes about... (and there are different types of bullets depending on the type of gun and all of that) about 280 meters per second, which is about 1000 kilometers per hour. And this is also roughly the speed of a jet. Of a jet...
 Complete this statement using less than or greater than-- that's what those symbols are-- for this kind of brackets there. So all they're asking is they have a 5 and they have a 2, and they want us to put either a less than sign for these brackets or a greater than sign.
Keeping in mind how much salt you should be taking if you're on a low-sodium diet, I'm just gonna write that here: "Low sodium diet".
For me they normally happen, these career crises, often, actually, on a Sunday evening, just as the sun is starting to set, and the gap between my hopes for myself and the reality of my life starts to diverge so painfully that I normally end up weeping into a pillow. I'm mentioning all this -- I'm mentioning all this because I think this is not merely a personal problem; you may think I'm wrong in this, but I think we live in an age when our lives are regularly punctuated by career crises, by moments when what we thought we knew -- about our lives, about our careers -- comes into contact with a threatening sort of reality.
It leads, in the worst cases -- in the analysis of a sociologist like Emil Durkheim -- it leads to increased rates of suicide. There are more suicides in developed, individualistic countries than in any other part of the world. And some of the reason for that is that people take what happens to them extremely personally -- they own their success, but they also own their failure.
We will never get to grade them, never get to grade people as they should. I'm drawn to a lovely quote by St. Augustine in "The City of God," where he says, "It's a sin to judge any man by his post." In modern English that would mean it's a sin to come to any view of who you should talk to, dependent on their business card.
It's not the post that should count.
According to St. Augustine, only God can really put everybody in their place; he's going to do that on the Day of Judgment, with angels and trumpets, and the skies will open. Insane idea, if you're a secularist person, like me. But something very valuable in that idea, nevertheless.
And then my favorite -- they really do have a kind of genius of their own, these guys -- my favorite is Sophocles' Oedipus the King: "Sex With Mum Was Blinding." (Laughter) (Applause)
(Applause) Chris Anderson: That was fascinating.
Alain De Botton: Yes, I think it's merely the randomness of the winning and losing process that I want to stress, because the emphasis nowadays is so much on the justice of everything, and politicians always talk about justice. Now I'm a firm believer in justice, I just think that it's impossible.
Or do you think that you can't, but it doesn't matter that much that we're putting too much emphasis on that? AB: The nightmare thought is that frightening people is the best way to get work out of them, and that somehow the crueler the environment, the more people will rise to the challenge.
Alain De Botton. AB: Thank you very much.
(Applause)
Welcome to the lathe soft jaw video series Brought to you by Haas Automation Soft jaws offer several benefits not provided by hard jaws
The clamping force on the part naturally decreases If the clamping pressure is set too high in an attempt to increase the clamping force The soft jaws will be distorted, actually decreasing grip force
This graphic illustrates what would happen if you did not cut to the nominal part diameter Undersize jaws will grip along six edges, whereas oversize jaws will grip only along the center of each jaw Our program is set to cut at the nominal part diameter
Once the jaws have been cut, make a shallow groove at the bottom of the jaws
Any work piece with sharp edges will now locate correctly against the jaw's back face Without this groove cut, a sharp-edged part will not locate correctly on the back face You will likely need to deburr the jaws when the machining is complete
In some cases, you won't be able to use the adjustable boring ring Because the part diameter is so large that the ring itself will block your cutting path That's exactly the case with this part here
Two step jaws are a good alternative to cutting two different jaw sets When part geometry is favorable, the larger pocket holds the uncut raw stock While the smaller pocket holds the half-finished part for the second operation
Well, unlike the previous example, this is a little bit harder to see. Certainly it's not the case that there's nice white space in between separating them. It seems to be a little tangled up, but we can figure out the number of components, and one way to do it is we can just start systematically seeing what's connected to what.
Calculate the area of a rectangular room that is 13 feet wide and 18 feet long. So the room might look like this. We're looking at a floor plan.
13 times 18. Now we're first going to worry about this 8 in the ones place, right?
18 is really 10 plus 8. So when we take this 8 in the ones place, 8 times 3 is 24, the 4 in the ones places.
Regroup the 2, which is really a 20, or carry the 2.
8 times 1, now this 1 is really a 10, so 8 times 1 is 8, plus 2 is 10, and there's no other digits, so we can write the whole 10 down here. So we now see that 8 times 13 is 104. Now let's worry about the next digit.
1 times 1, we ignore this 2. That was from the other digit so we ignore it.
1 times 1 is 1. So you see that 8 times 13 is 104, 1 times 13, or we should say 10 times 13, because that 1 is in the tens place, is 130.
18 is the sum of 10 and 8, so 18 times 13 is going to be the sum of these two numbers. So it's going to be 104 plus 130.
4 plus 0 is 4, 0 plus 3 is 3, 1 plus 1 is 2. So the area of the room is 234 square feet, or you could call it feet squared, however you want to do it. I'll write it like this: square feet.
MlSTAKES OF KASHAY-VlSHAY TOWARDS FAMlLY MEMBERS Let us do special pratikraman for our extended family members and [for] our family members because even in this [case]... they have come together with us in this life, because in our past life... the attachment- abhorrence(raag-dwesh), illusionary attachment(moha) are the main reason and the rule is such that Whosoever we feel extreme dwesh for, that very person will return as our closest relative in the next life
So, market size doesn't need to be a four-page business school analysis. So if you went to business school, feel free to do the analysis. But it really is at first a back of the envelope calculation.
I know what you're thinking. You think I've lost my way, and somebody's going to come on the stage in a minute and guide me gently back to my seat. (Applause)
"Here on holiday are you, dear?"
(Laughter)
"Come to visit the children? How long are you staying?" Well actually, I hope for a while longer yet.
I wrote some code to read in the marvel data as a barpartate graph and then to build the character by character graph and then find the top k strength and I just reuse the heap code from the last unit to do that. The new part to focus on is right here. So it goes like this.
All Haas machines have safety door locks to prevent the operator doors from being opened while the machine is in operation Looking at the side of the control pendant The upper key lock controls the Memory Lock function which restricts access to editing programs and changing settings in the locked position
You can turn the spindle clockwise or counter clockwise by pushing the [CW] or [CCW] buttons to aid in setting tool offsets The spindle will turn at a maximum of 750rpm With the key switch still in Setup mode and the operator doors now open
Round 423,275 to the nearest thousand. So let me rewrite it: 423,275.
423,000. So this is our choice.
Round up to 424,000 or round down to 423,000. And to figure it out, we just look at the digit one place to the right of the 3, so we look at the 2 right there. If that digit is 5 or greater, you round up.
2 is definitely less than 5, so we just round down, so it is 423,000. Now just to visualize what this means to the nearest thousand, if I were to do a number line-- and you don't have to do this. We've gotten the answer, but just to have a little bit better visualization of it, if I were to increment by thousands, you might have 422,000, 423,000.
Alright, so hopefully you used some tools to make that a little bit simpler for you. If we load up the developer tools here, we can see that we've already got a syntax error. And if we go over, and click right here on line 28, and it'll take us right to where the offending error is.
So, the problem is right here: you see that local user ID colon -1 doesn't have a comma after it, it just ends and since it was expecting a comma, well Javascript inserts a semicolon, and that causes issues. So let's go ahead and fix that one. Okay.
Here's one last topic, I'd like to cover in this unit. And again, it's related to the analysis of graphs and paths, and using variance of depth-first and breadth-first search to answer questions about the graph. Here's a little graph that I drew and one thing that we might notice is that, everybody is connected to everybody else, but there is this sort of weak edge.
Tarjan is responsible for some of the most amazing graph algorithms. A lot of which are based on the ideas of building trees, spanning trees using depth-first and breadth-first search. Back in college, my friend ??? and I used to refer to him as Tarjan, Lord of the trees.
Starting from B, we look at all the neighbors of B which in this case are A and C, and we haven't build any of them into the graph yet, so we can add them into the graph. And now, we do essentially a search just as we're doing before, consisted of A and C.
So from A, we look at the neighbors of A. The neighbors of A are B and C. Now, the BA edge is already in there, but the BC edge is not. So, we're going to add a special kind of edge because this is an edge between two nodes that are already existing.
We have B which the edges are already in there and we also have an edge to E which we haven't seen yet. We add that edges and then we proceed from E. Now, E has three edges back to C which we already have and also to D and G.
E is already in there but we can add in F at the tree edge. We look back at G, G has neighbors F and E. The E one is in there and the F one is not, so we add that non-tree edge in there,
Because F is already in the diagram but that edge was no not. And then from F, there is connection to D and G and those were already in the graph. So basically, what we've done now is we rewrote the original graph as a rooted tree.
E needs a number. Well, E can't get it's number until it's children have been numbered but those haven't been numbered yet, so let's number those.
D--D should get a number but first it's children have to get a number. This is a, you know, children first sort of scheme. These children has one child and that's F.
B, all its children have been numbered, so now B can get it's number. So we've now post ordered all the nodes in the graph. So, just to make sure that you're understanding that process, here's a different tree.
Clearly, we're living in a moment of crisis. Arguably the financial markets have failed us and the aid system is failing us, and yet I stand firmly with the optimists who believe that there has probably never been a more exciting moment to be alive. Because of some of technologies we've been talking about.
I didn't always love unintended consequences, but I've really learned to appreciate them. I've learned that they're really the essence of what makes for progress, even when they seem to be terrible. And I'd like to review just how unintended consequences play the part that they do.
"This I will not treat. This I cannot treat." They were very conscious.
The lesson of the Titanic, for a lot of the contemporaries, was that you must have enough lifeboats for everyone on the ship. And this was the result of the tragic loss of lives of people who could not get into them. However, there was another case, the Eastland, a ship that capsized in Chicago Harbor in 1915, and it killed 841 people -- that was 14 more than the passenger toll of the Titanic.
The reason for it, in part, was the extra life boats that were added that made this already unstable ship even more unstable. And that again proves that when you're talking about unintended consequences, it's not that easy to know the right lessons to draw. It's really a question of the system, how the ship was loaded, the ballast and many other things.
(Applause)
As a boy, I loved cars. When I turned 18,
I saw the concept first in the DARPA Grand Challenges where the U.S. government issued a prize to build a self-driving car that could navigate a desert. And even though a hundred teams were there, these cars went nowhere. So we decided at Stanford to build a different self-driving car.
And the unimaginable happened: it became the first car to ever return from a DARPA Grand Challenge, winning Stanford 2 million dollars. Yet I still hadn't saved a single life. Since, our work has focused on building driving cars that can drive anywhere by themselves -- any street in California.
Do you realize that you, TED users, spend an average of 52 minutes per day in traffic, wasting your time on your daily commute? You could regain this time. This is four billion hours wasted in this country alone.
Remember, your goal here is to start with a series of hypotheses. That's all you'll have on day 1. If you're a domain expert, maybe you know a little more, but it's okay because you're just kind of guessing here.
You start with, "Here's who I think my customers are," but then you get out of the building and you start running experiments, and you find out, "Oh, I was right," or, more often on your first guesses, "I was wrong."
And because we're going to do these experiments cheaply, inexpensively, and up front, we're going to save all the enormous waste we would do if we waited until we launched the product and did an expensive marketing campaign and then, only then, realizing that, "Oops! These weren't our customers," or, "These were our customers, but we built the wrong features."
So let's dive down a level deeper and first focus on what's the jobs needed to be done. That is, what is the customer segment trying to get done?
And is it a problem or need? This phrase "jobs to be done" was first popularized by Clayton Christensen, who wrote a series of books. The Innovator's Dilemma and The Innovator's Solution should probably be on any entrepreneur's reading list.
And what Christensen said is, "What functional or social jobs are getting done?"
That is, does the customer want to perform or complete a specific task or solve a problem, or are they trying to look good, gain power or status?
Or are there some emotional jobs?
Do they want to look better, feel good, feel more secure?
And what basic needs are you helping your customer satisfy?
Is it entertainment, is it dating, is it something hard wired into the human psyche?
The language challenge by Claude Piron Facing up to reality Hello!
16 fluid ounces plus 3 pints plus 4 quarts is equal to how many gallons? Now the one unfamiliar thing here that we haven't seen before is this 16 fluid ounces. We've seen ounces before, but not fluid ounces.
A human child is born, and for quite a long time is a consumer. It cannot be consciously a contributor. It is helpless.
And, therefore, what I say, you have to fake it and make it. (Laughter) You need to.
Now, this is great for JSON, but what if we want to grab something else, say, a sound file. To do that, we need to set the response type of the XMLHttp request object to arraybuffer and what that will do is specify that it is binary information rather than text that we can then decode as necessary. What we like you to do is create another XMLHttp request but this time we're going to request "bg_menu.ogg", a sound file and set the response type to arraybuffer.
 Let's say that today-- and we'll call today Day 1-- Day 1 is a Monday.
What I want to figure out is what is the Day 300 going to be? What day of the week will Day 300 be? And I encourage you to pause the video and think about that a little bit.
9 10. I'm almost writing a calendar out. 11, 12, 13, 14, 15, 16.
Well, as you see when I started drawing this grid here, this grid has rows. And each row, you have seven days in it. And that makes sense.
What is the remainder when you divide 16 by 7? 16 divided by 7 is going to be 2. 2 times 7 is 14.
So when we divide, we've historically cared more about this 2. We normally care more about well, how many times does it go into it. But now, the remainder is actually interesting.
Subtract, you get 2. Bring down a 0. 7 goes into 20 2 times.
If you're doing more than just watching these lectures, one of the things you're going to be staring at a lot is the Business Model Canvas. If you're watching this video, the first thing I suggest is stop, go to businessmodelgeneration.com, and download the canvas and print out bunch of copies. Then go get a bunch of yellow stickies and a red pen because that's what you're going to be using for the next couple of weeks.
I'm a designer and an educator. I'm a multitasking person, and I push my students to fly through a very creative, multitasking design process. But how efficient is, really, this multitasking?
Today, we're going to be talking about customer relationships. In other words, how do you get, keep and grow customers. So in the last lecture, you remember the business model canvas, all the 9 components of a startup.
To make some of the issues, we're going to be talking about simpler. We're going to focus in on some sense very simple kinds of problems. Problems that take inputs just like what we've been looking at.
Compute twenty-five hundred times 80, or 2,500 times 80. Now, we could just do this multiplication problem like a traditional one, but when you have these numbers with a lot of zeroes there, and it actually sometimes helps you do it in your head, is to kind of think about the zeroes later. And the reason why we can do that-- let's rewrite this multiplication problem.
2,500 times 80. This is equivalent to-- 2,500 is what? It's 25 times 100.
2,500 is 25 times 100 times 80. And what's 80?
80 is 8 times 10. And in multiplication, you can rearrange it any way you like. You can change the order when it's all a bunch of numbers being multiplied.
And whenever you multiply powers of ten, the way you can think about it is you just literally add the zeroes. You had two zeroes here. You have one zero here.
100 times 10 is 1,000. And when we multiply this times whatever this is, we'll literally just add three zeroes to the product, so that's why this is useful.
25 times 8.
5 times 8 is 40. Put the zero down.
Carry the 4.
8 times 2 is 16 plus 4 is 20. So it's an even 200, which makes sense.
4 times 24 is 100, or four quarters make a $1.00, so eight quarters would make $2.00, so that all makes sense. So this part right here is 200, so we're going to multiply 200 times 1,000. The easiest way to think about it is you just add the zeroes when you're multiplying times a power of ten.
200,000. You could've multiplied it out in the traditional sense, but it's good to see this-- I guess you could call it a trick or a way to do it in your head a little bit. And you'll see that more and more, the more practice you get.
When did you first hear about "Sal Khan" or "Khan Academy"?
In Google's case we were looking for approaches that were new in education.
Many many people think they're doing something new, but they're not really changing the approach.
Which with Sal, he said "what we are going to do is not only we're gonna make these interesting ten minute videos, but we are going to measure whether it works or not"

What do we know about the future? Difficult question, simple answer: nothing. We cannot predict the future.
(Applause)
We are drowning in news. Reuters alone puts out three and a half million news stories a year. That's just one source.
Remember, we've been talking about pass/fail signals and experiments. As you get out of the building and start talking to these potential customers you need to set up some experiments. How do I know these are the right customers or the right buyers?
So the answer is for the linked in, there are two sides to this market. There are the workers as a customer segment and there are recruiters. For Visa, you would have banks and merchants.
We're asked to simplify 12 plus, and then in parentheses, 5 minus 1 times 3 to the second power, or 3 squared, minus 8 divided by the square root, or really the principal root, of 4. Now, whenever you see something like this, you really just want to put your brain into order of operations mode. And just to remind ourselves, the top priority goes to parentheses, so I'll just draw some parentheses there.
And then finally, you do addition and subtraction.
So let's apply that to this over here. So we have one set of parentheses right there. You have that parentheses, and inside you have 5 minus 1, so we want evaluate that first of all.
3 to the second power is 9. That's the same thing as 3 times 3. So let me write that down just as a review.
The square root of 4, what times itself or what positive number, or non-negative number, I should say, times itself is equal to 4? Well, it's 2, right? This is the same thing as the square root of 2 times 2, which is equal to 2.
12 plus 36-- I'll do this right here-- is 48. So we have 48 minus 4. When you evaluate that, 48 minus 4 is just 44.
Now let's do Part b).
Find the average velocity of the particle for the time period between time 0 and time 6.
So the easy way to think about this, average velocity, is that your average, or one way to think about it, the distance that you travel, sometimes I use "d" for distance or "s" for displacement
I just received this drug calculation problem from a nursing student, and I think it's essential that the nursing students out there are able to do this, just in case I'm the patient receiving the drug. So let's do it. And I think it's an interesting unit conversion problem for pretty much anyone who wants practice with unit conversion.
And this is the dosage that the doctor's requesting. They're saying five milligrams per pound of patient weight-- I'll just write per pound of patient weight-- every twelve hours. This is what we're supposed to do.
We have 0.9-- I'll write a 0 in front. My wife, who is a doctor, says it's essential to write the zero in front of the decimal. We have 0.9 grams per milliliter of solution.
So there's a couple interesting things here. We have to figure out the dosage in terms of milliliters. We have to-- oh, actually, I didn't even tell you the question.
This is equal to-- let's see. five times two is ten. 5 times 0.2 is 1. So this is equal to eleven.
So now we have everything in terms of grams, but we want it in terms of milliliters. The question is, how many milliliters of solution per dose? So let me go down here on this line right here.
So in our solution, how many grams are there per milliliter? Well, they told us. There are 0.9 grams per milliliter.
And then we multiply it out. 11/1,000 times 1 over 0.9. So I'll just keep-- let me just write it like this.
All right, so the answer I'm looking for is this one, which is a pretty simple reduction. Let me step through it, just in case it wasn't clear.
Compute 23 times 44. And maybe the hardest part of this problem, or maybe the first hard part, is to recognize that that dot even means multiplication. This could have also been written as 23 times 44, or they could have written it as 23 in parentheses times 44, so you just put the two parentheses next to each other.
4 times 3 is 12.
Carry the 1. This blue 1 is from last time. You ignore it now.
So when you multiply 44 times 23, it's going to be 4 times 23, which is 92, plus 40 times 23, which is 920. I just want to make sure we understand what we're doing here. And so we can take their sum now.
There's one more case of partial fraction expansion or decomposition problems that you might see, so I thought I would cover it. And that's the situation where you have a repeated factor in the denominator. So let's see, I've constructed a little problem here.
Minus 19 plus 15, that's minus 4, plus 6, that is equal to 2. There you go. Now let's try to solve for-- let's see, what can we do?
2 squared. So it's 24, minus 38-- 19 times 2-- plus 15. Let's see, 24 plus 15 is 39, minus 38, that is equal to 1.
2 times 0 minus 2 squared. So that's minus 2 squared, so that's 2 times 4. Plus B-- that's what we're trying to solve for; we already solved for everything-- B times minus 1, right?
Minus 1 times minus 2 is plus 2. Oh, and we shouldn't have written the C here, we know what C is. C is 1.
The hairiest problem that you might see with three variables on an actual exam is probably something like I showed you in the previous example, or what I just showed you right now. Anything hairier than that, you'd probably end up using a computer. But you should know how to do it, because if you have a computer and you're solving a real world problem that is a
Let's say we we've been hanging out in scenario E for a bunch of days. On average we've been catching one rabbit, but gathering 280 berries. We were, I guess, in a berry mood, so this is scenario E right over here.
They came... They came with their bulldozers... and they came with their soldiers. I never left my house and defended it strongly, but they didn't listen to me.
Mayors come and go, presidents come and go, and the poor continue in the same situation. It's always the same story.
They say these mega-projects bring development, we've been to several countries and this development does not exist.
[PEOPLE BEFORE PROFlT]
Forced evictions are when people are forcibly moved from their home, from their land, from their community, from their neighborhood, from their culture, against their will or desire for projects that often have no benefit to the communities that are being evicted. Forced eviction normally is done by companies, private companies with the assistance of the local authorities or the government. They evict people from their original place without fair compensation, and using force, using violence.
'If you don't accept this offer, a tractor will come and destroy your home.' You have not respected our human rights, not as Mexicans, not as citizens, and not as humans. You've never consulted or asked the community if we agree with being flooded or resettled.
During the eviction, the most repeated pattern is use of force and violence, and violation of all sorts of fundamental and human rights that we can possibly imagine. Normally the residents are in a state of shock. Sometimes houses are destroyed with residents' belongings still inside, so besides losing their homes, they lose everything they own.
Everyone who lives around here: You should stand up!
(The people united will never be defeated!) We see a pattern of resistance, through petitions, meetings, negotiations with the government, protests, public demonstrations. Solidarity is the most important aspect of resistance.
When I was 11, I remember waking up one morning to the sound of joy in my house. My father was listening to BBC News on his small, gray radio.
"Listen, my daughter, you can lose everything you own in your life. Your money can be stolen. You can be forced to leave your home during a war.
(Applause) When I returned to Afghanistan, my grandfather, the one exiled from his home for daring to educate his daughters, was among the first to congratulate me. He not only brags about my college degree, but also that I was the first woman, and that I am the first woman to drive him through the streets of Kabul.
(Applause) My family believes in me. I dream big, but my family dreams even bigger for me.
Less than a month ago, he and his daughter were on their way from SOLA to their village, and they literally missed being killed by a roadside bomb by minutes. As he arrived home, the phone rang, a voice warning him that if he sent his daughter back to school, they would try again. "Kill me now, if you wish," he said,
"but I will not ruin my daughter's future because of your old and backward ideas." What I've come to realize about Afghanistan, and this is something that is often dismissed in the West, that behind most of us who succeed is a father who recognizes the value in his daughter and who sees that her success is his success. It's not to say that our mothers aren't key in our success.
(Applause) Afghanistan looks so different from here in America. I find that Americans see the fragility in changes.
To me, Afghanistan is a country of hope and boundless possibilities, and every single day the girls of SOLA remind me of that. Like me, they are dreaming big. Thank you.
(Applause)

I sensed some confusion coming out of the last video on inferior goods. So, I thought I would do another one. So let's make --
It took a much bigger chunk out of this blue than a chunk was taken out of it by the orange. And also, the demand for this very expensive car went up And that was at a particular price point.
In the last video, I told you that if I had a hyperbola with the equation x squared over a squared minus y squared over b squared is equal to 1, that the focal distance for this hyperbola is just equal to the square root of the sum of these two numbers. The square root of a squared plus b squared. In this video I really just want to show you that.
--that that number is a constant regardless of where we are on the hyperbola. In fact the locus of all points are-- the hyperbole in fact is all of the points that satisfy that condition. And we learned in last video just by taking the difference of the distance, we picked this point and we said, OK, what's that distance minus that distance.
So d1 minus d2 is equal to-- I'm going off the video screen
--d1 minus d2 is equal to 2a. So let's use this fact right here that d1 minus d2 is equal to 2a, to try to prove this. Right there.
--this becomes x plus f, right, minus minus, squared plus y squared is equal to 2a plus the square root of x minus f squared plus y squared. Now, to get rid of these radicals, let's square both sides of this equation. The left hand side, if you were to square it just becomes x plus f squared plus y squared.
--that's equal to x minus f squared plus y squared. And already it looks like there's some cancellation that we can do. We can cancel out-- there's a y squared on both sides of this equation --so let's just cancel those out.
Subtract y squared from both sides of the equation. And let's multiply this term out. So this right here is x squared plus 2xf plus f squared.
Minus y squared minus a squared mine is a squared is equal to 1. This cancels with this. And we get something to starting to look like the equation of a hyperbola.
And here's a graph--it's kind of a binary tree, starting from h and expanding the nodes using breadth first search, when node o be added to the open list. So, assuming that h is 1 and each of the nodes is going to get added one at a time into the open list, eventually o will get added. What level will it be.
Let's say we have a path in the xy plane.
>>Cutts: Hey everybody. We're back for another round of Webmaster Videos.
He wrote that searches could be navigational, they could be informational, or they could be transactional. And that expresses a lot of what people are looking for. Navigational, they might search for HP or IBM, they're looking for the home page.
Where we left off after the meiosis videos is that we had two gametes. We had a sperm and an egg. Let me draw the sperm.
And actually, it comes from the word for mulberry because it looks like a mulberry. So actually, let me just kind of simplify things a little bit because we don't have to start here. So we start with a zygote.
Now, once the morula gets to about 16 cells or so-- and we're talking about four or five days. This isn't an exact process-- they started differentiating a little bit, where the outer cells-- and this kind of turns into a sphere.
Let me scroll over. I don't want to go there. And then the inner cells, and this is kind of the crux of what this video is all about-- let me scroll down a little bit.
And this is what's going to turn into the organism. And so, just so you know a couple of the labels that are involved here, if we're dealing with a mammalian organism, and we are mammals, we call this thing that the morula turned into is a zygote, then a morula, then the cells of the morula started to differentiate into the trophoblast, or kind of the outside cells, and then the embryoblast. And then you have this space that forms here, and this is just fluid, and it's called the blastocoel.
A very non-intuitive spelling of the coel part of blastocoel. But once this is formed, this is called a blastocyst. That's the entire thing right here.
Sometimes it's called the blastosphere.
And I want to make it very clear that these are essentially the same stages in development. These are just for-- you know, in a lot of books, they'll start talking about frogs or tadpoles or things like that, and this applies to them. While we're talking about mammals, especially the ones that are closely related to us, the stage is the blastocyst stage, and the real differentiator is when people talk about just blastula and blastospheres.
And the word essentially comes from, you know, like a plastic can turn into anything else. When we say that something has plasticity, we're talking about its potential to turn into a lot of different things. So the theory is, and there's already some trials that seem to substantiate this, especially in some lower organisms, that, look, if you have some damage at some point in your body-- let me draw a nerve cell.
In 2008, Cyclone Nargis devastated Myanmar. Millions of people were in severe need of help. The U.N. wanted to rush people and supplies to the area.
Google Mapmaker is a technology that empowers each of us to map what we know locally. People have used this software to map everything from roads to rivers, from schools to local businesses, and video stores to the corner store. Maps matter.
(Applause)
Causing Others To Suffer By Attacking Them Due To The Intensity Of Kashays Let's take it [samayik] on this... "Attack"
Ravan and Sitaji.... In the previous life, Sita had intense abhorrence for Ravan so in her second birth she took her revenge (veyr) by becoming the evidentiary instrument (nimit) for his death
Oh Dada Bhagwan,
Oh Shri Simandhar Swami Prabhu, give me the strength to do a samayik with pure applied awareness of the Self (shuddha upyog), [mistakes] that have occurred throughout my entire life due to the intensity of attachment (moha) for worldly interactions [due to the] intensity of maan (pride) [due to the] intensity of lobh (greed) kashay
Or else due to the intensity of dharyu karvanu (getting ones way) whichever individual, whom I have attacked and inflicted suffering upon.
Due to the attack from any person as a reaction to that person if I have broken their ego for all such mistakes may I heartily repent profusely and wash away [these mistakes] give me the absolute strength to do such a samayik.
By maintaining the awareness of separation of the Self and the non-self, Give me the absolute energy (shakti) to do such a samayik [I surrender] my mind-speech-body
Let's do another conic section identification problem.
As we discussed, some businesses are multi-sided. In this case, let's take a look at the 2-sided market and match the market with the appropriate business.
654.213의 3의 자릿수는 뭔가요? 좀 생각해 보도록 하죠. 그러려면 일단 다시 써 보고 이번엔 다 다른 색으로 써 보겠습니다. 그러니까 654_ 소수점_213. 제 생각에 우린 소수점 왼쪽이 뭔지 꽤 잘 알고 있을 것 같습니다 우리는 여기 이게_ 좀 더 무난한 색으로 할게요_ 백의 자릿수, 아니면 십의 제곱이라는 것을 알고 있습니다. 그거 여기다 좀 더 큰 글씨로 써 놓을게요. 그러니까 여기 이건 백의 자릿수, 아님 십의 2승의 자릿수이니까 결국 백과 같다는 겁니다. 여기 이건 십의 자릿수입니다, 십의 1승과 똑같은 거죠. 여기 있는 것은 일의 자릿수고, 10의 0승과 같습니다. 그 다음 소수점 오른쪽으로 한 자리 옮기면 10분의 1을 의미하는 것이 됩니다. 이것은 10분의 1 아니면 10의 마이너스 1승이라고 볼 수 있겠죠. 그리고 이 자주색 숫자로 가면, 그러니까 오른쪽으로 두 자리 옮기면 100분의 1 아니면 10의 마이너스 2승입니다. 그리고 마침내, 이 3은 1000분의 1을 뜻합니다. 1000분의 1 아니면 10의 마이너스 3승을 의미하죠. 이제 질문에 대답하자면 654.213에서 3의 자릿수는 무엇인가요? 자릿수는 1000분의 1입니다. 그거면 실질적으로 문제에 대한 답은 나왔죠. 하지만 우리가 이것이 뜻하는 바가 무엇인지 정확히 이해하는지 알기 위해서, 이 숫자를 다시 써 볼 겁니다. 우린 이 숫자를 600으로 다시 쓸 수 있어요. 600 더하기 50 더하기 4 더하기 10분의 2 더하기 1000분의 3으로요. 아니면 자릿수에 대해서 우리가 제대로 알고 있는지 확인하기 위해서 우린 이 숫자를 6 곱하기 100 더하기 5 곱하기 10 더하기 4 곱하기 1_ 계속 잘못된 색깔로 하고 있네요_ 더하기 10분의 1 곱하기 2, 더하기 100분의 1 곱하기 1, 그리고 마지막으로, 더하기 1000분의 1 곱하기 3. 그러니까 희망 사항이지만, 이렇게 적어 놓는다면 우리가 자릿수라고 할 때 어떤 의미인지 이해할 수 있을 겁니다. 소수점에서 왼쪽으로 세 번째 자리에 있는 6은 100의 자릿수이므로, 600을 의미하죠. 이건 10의 자리에 있기 때문에 5 곱하기 10을 의미하고요. 이건 4 곱하기 1을 뜻합니다.

My name is Emiliano Salinas and I'm going to talk about the role we members of society play in the violent atmosphere this country is living in right now. I was born in 1976. I grew up in a traditional Mexican family.
"If you want your ransom come and get it. We'll be waiting for you right here." They stayed there.
"a soldier in each son." I think the biggest insult, the worst way you can offend a Mexican is to insult their mother. A mother is the most sacred thing in life.
"Be the change you wish to see in the world." Today in Mexico we're asking for Gandhis. We need Gandhis.
Multiply 1 and 3/4 times 7 and 1/5. Simplify your answer and write it as a mixed fraction. So the first thing we want to do is rewrite each of these mixed numbers as improper fractions.
And the reason why this makes sense is 1 is 4/4, or 1 is 4 times 1 fourths, right?
1 is the same thing as 4/4, and then you have three more fourths, so 4/4 plus 3/4 will give you 7/4.
So that's the same thing as 1 and 3/4.
Same exact process. We're going to still be talking in terms of fifths. That's going to be the denominator.
5 goes into 6 one time. 1 times 5 is 5. You subtract.
5 goes into 13 two times. And you could have immediately said 5 goes into 63 twelve times, but this way, at least to me, it's a little bit more obvious.
We're asked to add 50 plus 0. Well, zero is nothing. So you can imagine that we're starting off with 50 of something, and if we add nothing to that 50, we're still going to have 50 of that something.
Write 7/4 as a mixed number. So right now it's an improper fraction.
7 is larger than 4. Let's write it is a mixed number. So first I'm just going to show you a fairly straightforward way of doing it and then we're going to think a little bit about what it actually means.
If we're dealing with fourths, 4 goes into 7 a total of one time.
Let me do this in another color.
A total of one time 1 times 4 is 4. And then what is our remainder?
7 minus 4 is 3. So if we wanted to write this in plain-- well, let me just do the problem, and then we'll think about what it means in a second. So you see that 4 goes into 7 one time, so you have one whole here, you have one whole ,and then how much do you have left over?
3 left over, but it's 3 of your 4, or 3/4 left over. So that's the way we just converted it from an improper fraction to a mixed number. Now, it might seem a little bit like voodoo what I just did.
7/4 is 4/4 with 3/4 left over. Now what is 4/4?
4/4 is one whole. So you have one whole with 3/4 left over, so you end up with 1 and 3/4. So that is the 3/4 part and that is your one whole.
So the number of wholes, or you can imagine, the number of whole pies. And then how many pieces do we have left over? Well, we have 3 pieces and each piece is 1/4, so we have 3/4 left over.
I told you to use a mathematical formula, so I cheated a little bit. I wrote a little piece of code to actually generate a complete graph and then return the number of edges in that graph. To make a complete graph, I just looped through all the pairs of nodes, and if one node was smaller than the other, then I made a link between them.
Part C find the average value of f on the interval negative 1 to 1. So the average value of a function over an interval is just going to be. So let's just write average.
Negative 1 to 1 of F of X, D of X. Divided by our change in X. So, divided by.
This first part, right over here, we can write as the integral from negative 1 to 0. What is F of X between negative 1 and 0?
It's 1 minus 2 sin of X. 1 minus 2 sin of X, DX. An then, plus this thing right over here. Plus the integral from 0 to 1 in what is our function, when it's, between zero, and one, it's e to the negative 4 X.
For the past 32 years I've looked into the mirror every morning and asked myself: If today were the last day of my life would I wanna do what I'm about to do today? And whenever the answer has been "no" for too many days in a row,
Divide. Simplify the answer and write as a mixed number. And we have 2 and 1/4 divided by 1 and 3/4.
2 and 1/4 divided by 1 and 3/4 is the same thing as 9/4 divided by 7/4. And we saw in several videos already that dividing by a fraction is the same thing as multiplying by its reciprocal. So this is equivalent to-- so these are all equivalent.
For the reciprocal of 7/4, you swap the numerator and denominator, or the top number and the bottom number, and you get 4/7. Now, we could just multiply these. We could just say this is 9 times 4, which would be 36, over 4 times 7, which is 28, and then try to put it in
7 times 1 is 7, and you're going to have 2 left over. You need 2 more to get to 9. So you're going to have 2 left over, so this is 1 and 2/7.
The Goal of Moksha
The goal (dhyeya) of Moksha, that means, it is a very strong matter - the implication of a dhyeya
Dhyeya means a very strong resolve. It implies, that which, you have to hold on to strongly. What is the difference between purpose [aim] and dhyeya?
After knowing Dada and receiving this knowledge, the talk of [having a] dhyeya begins. Up until then, we were all stuck in [achieving] worldly aims. Now, the stronger our goal is, the more unwavering it is, then that is a true dhyeya.
If someone praises us, how do we feel?
Do you not feel good and elevated?
Not only do you like what the person is saying, but you also develop fondness for that person as well. We become his devotee (bhagat). Your dhyeya is being missed at this point.
Then if we go somewhere, like to attend a wedding or a party or something, and if someone in the room besides yours is talking... ... and mentions the name "Vitthal" and you happen to hear that, then immediately you will eavesdrop you will listen in even if it is in the middle of night.
What must they be saying about me? What are they talking about? Oh no! you should not eavesdrop.
This leads to so much disease inside. How many of you in your life have listened to this way by putting your ears against the door? Raise your hands.
This is a seriously bad habit. It is considered a strong form of deceit (kapat). It is a serious form of deceit (kapat).
It is hard [to bear], deceit will not let you go to Moksha. You do not see it as it is. Deceit conceals the mistakes, it keep covering them up, covering them.
Understand? Deceit brings heavy veils of ignorance (avaran). Then there are many others who are kacha kanna (gullible to hearsay)
And in that obstinacy, what causes a greater loss - not only is he obstinate but he takes pleasure in it as well That is a heavier loss - double [the loss] He takes pleasure in being obstinate; he tastes the sweet juices (garvaras) of doership of the adayee
If someone gives us the slightest praise, we forget we are pure Soul. And we forget he is pure Soul and we develop attachment (raag) for him. Women should beware of pride.
Now, in old age it is not a problem. But in youth, young men praise girls so much, boys praise girls by saying, "pretty, pretty, beauty, beauty," And the girls get trapped in vishay.
And an even bigger issue than this is the intoxication that, "I know something" and the stature of a preacher (updeshak)." These two are very dangerous things. It is Dada's words, a Gnani's speech.
But your intellect at that time will feel, "oh, I made him understand so well". "I have got some sort of power to preach and make others understand." When it comes to attending Satsang (discourses), he says, "Forget it.
Then he may think, "oh, I live so far from the satsang venue, how can I go?" So in this way he will avoid going for this reason also. This [thought] has caused antaray for attending satsang.
If someone is immensely irritated, he may say, "What kind of gnan is this? Dada's gnan is difficult to follow. Let it be.
in this way, Chandan has caused antarays for attending satsang
Some have a high awareness for worldly matters. To make his worldly life glorious, he will ensure not to make any mistakes. He stays in full awareness to avoid making any worldly mistakes.
Once he understands the high value of the pure Soul and Moksha. That this world is temporary, and the pure Soul is permanent. The goal is to seek freedom from the worldly life by solving it with equanimity.
What else is left?
Yes, we should not see a single fault in Him, who has given us this gnan - that is [we should not see see] Dada's faults, faults of Dada's gnan, faults of Akram Vignan And we should not see faults of those who are directly instrumental (nimit) [one-to-one] for us to get this gnan, like Niruben.
Just as witch leaves one house, you be a witch and leave us.
Let not your firm inner resolution (niyanu) go to waste And Rituals - do not become the doer of the rituals. It is happening per one's discharge karma - and the intent that "this must be done" should not be there.
And apart from Real (pure Soul), nothing is worth asking for in the Relative. There is illusionary attachment (moha), there is deceit (kapat), all these things also come in this But these have been in seen in the past - sweet juices of doership, (garvaras), pride (maan), kapat
So let us start the samayik.
Oh Dada Bhagwan, Oh Shri Simandhar Swami Prabhu, Give me the strength to do a samayik with pure applied awareness of the soul (suddha upyog)
Now, back in the early 90's, specialty hardware was used to get smooth graphics on early machines. Things like the NES, Genesis, and Gameboy had custom hardware that was built into the form factor that was allowed you to draw tons and tons of tiles very quickly on modern screens. Now desktop computers at the time didn't have that much power, in fact, they didn't have any of that specialty hardware at all.
The same studio that went on to actually create the first person shooter genre with titles such as Wolfenstein, Doom and Quake. Now, the trick that Carmack realized to get the same performance from the specialty hardware on the desktop, was actually an optimization. See, these early machines weren't too good at actually copying pixels over here to over here in memory.
So in summary, the questions you want to ask are how big can this be, how much of it can we get, what's the growth rate of the market, is the market itself declining or is it in flux or is it taking off? and most importantly here is talk to customers and the sales channel, and next important is you can get some pretty good market size estimates by competitive approximation if it's an existing or resegmented market, or even if we're going to clone a market outside the US. Next important is Wall Street Analytic Reports are great.
Market research firms like Forrester and Gartner are great, but something to keep in mind about market research forecasts going forward. Market research data is wonderful on the size of markets in the past, but if market researchers were great at predicting the future, they'd actually be running hedge funds, so one of the things I don't accept from my students is,
"and it's going to be a $40 billion business in the next 7 years." Well, what's its size now? Zero.
We're trying to figure out what the running time is asymptotically Θ for selection and insertion as a function of n and K and then we can substitute in the value of K. If there's n elements in our list and we're interested in the top K, what the selection algorithm does is it goes through the elements one at a time and for each of these n elements it tries to figure out where in this list of K it needs to go. For each of these n, it does an insertion or a selection.
loglogn is similar. We end up with n(loglogn), which is better than nlogn. And finally I guess it'd be kind of obvious at this point if we substitute logn in for K, we have nlogn for selection insertion but we also have nlogn for sorting so they're actually the same.
So we're asked to add 3/15 plus 7/15, and then simplify the answer. So just the process when you add fractions is if they already-- well, first of all, if they're not mixed numbers, and neither of these are, and if they have the same denominator. In this example, the denominators are already the same.
that is a second section, and then a third section, fourth section, and then we have a fifth section. Let me copy and paste this whole thing. So that's five sections right there.
Let's write 0.8 as a fraction. So 0.8... the 8 right over here is in the tenths place. So you can read this as 8 tenths and we can write that literally as being equal to 8 tenths or 8 over 10.
Now we draw our image at location 192 by 192. Which as you can see placed the top left corner of the image, 192 by 192 pixels up from the top left corner of the canvas, which has been conveniently placed at location zero, zero on the page. That is to say that on the canvas, the origin of its coordinate system, i.e., the

I come from Lebanon, and I believe that running can change the world. I know what I have just said is simply not obvious. You know, Lebanon as a country has been once destroyed by a long and bloody civil war.
More than that, how do you convince people to run a distance of 26.2 miles at a time they were not even familiar with the word "marathon"? So we had to start from scratch. For almost two years, we went all over the country and even visited remote villages.
In 2005, our prime minister was assassinated, and the country came to a complete standstill, so we organized a five-kilometer United We Run campaign. Over 60,000 people came to the start line, all wearing white T-shirts with no political slogans. That was a turning point for the marathon, where people started looking at it as a platform for peace and unity.
Welcome to part two of the presentation on quadratic equations. Well, I think I thoroughly confused you the last time around, so let me see if I can fix that a bit by doing several more examples.
So let's just start with a review of what the quadratic equation is. The quadratic equation says, if I'm trying to solve the equation Ax squared plus Bx plus C equals 0, then the solution or the solutions because there's usually two times that it intersects the x-axis, or two solutions for this equation is x equals minus B plus or minus the square root of B squared minus 4 times A times C. And all of that over 2A.
2 times negative 9-- 2A.
Let's try to simplify this up here. Well, negative negative 9, that's positive 9. Plus or minus the square root of 81.
30 times 6 is 180. And then 180 plus another 36 is 216. Plus 216, is that right?
180 plus 36 is 216. All of that over 2A.
2A we already said is minus 19. So we simplify that more. That's 9 plus or minus the square root 81 plus 216.
2 plus 9 plus 7 is equal to 18.
So let's see how many times 9 goes into that. I'll do it on the side here; I don't want to be too messy. 9 goes into 2 97.
3 times 27. 27-- it goes 33 times, right? So this is the same thing as 9 plus or minus the square root of 9 times 33 over minus 18.
And 9 is a perfect square. That's why I actually wanted to see if 9 would work because that's the only way I could get it out of the radical, if it's a perfect square. As you learned in that exponent rules number one module.
3 plus or minus the square root of 33 over minus 6. And we are done. So as you see, the hardest thing with the quadratic equation is often just simplifying the expression.
One x value is x equals 3 plus the square root of 33 over minus 6.
And the second value is 3 minus the square root of 33 over minus 6. And you might want to think about why we have that plus or minus. We have that plus or minus because a square root could actually be a positive or a negative number.
Let's say I wanted to solve minus 8x squared plus 5x plus 9. Now I'm going to assume that you've memorized the quadratic equation because that's something you should do. Or you should write it down on a piece of paper.
4 times 8 is 32 and the negatives cancel out, so that's positive 32 times 9. Positive 32 times 9, let's see.
30 times 9 is 270. It's 288. I think.
288. We have all of that over minus 16. Now simplify it more.
And all of that over minus 16. And I think, I'm not 100% sure, although I'm pretty sure. I haven't checked it.
Now in the beginning of this unit I did a little magic trick having to do with coloring in region in a map. This problem is sometimes called map coloring. and just to remind you, the idea there is that each of the region in the map we're going to assign some color to it with the constraint that there can't be the same color in two adjacent regions on the map. because then it would kind of make it look like one big region. We can actually think of this as a problem on graphs.
In particular, we're going to make each region on the map correspond to a node on the graph and we're going to connect two nodes on the graph if they share a border and therefore can't have the same color on the map. "a" shares a border with "b" and "f"
"f" shares borders with "g", "b", and "a"
"b" shares borders with "a" and "f" that we haven't already and "g" and "c"
"c" shares borders with "d" and "h"
"h" shares borders with "g" and "e" and "d". "gcde" "d" and "e" share a border Did I get everything? "h" doesn't connect to "b". "g" doesn't connect to "c" - yes it does. "g" has borders with "f", "b", "c", and "h."
"ok i've got a group of people, here is their friend network, and what I'd like to do is group them into K different groups so that within each each group there is no pairwise friends" so you can think of this as building mixer, like a party where you want to invite your friends but you want them to interact with people they aren't already friends with
Alright, now that we've seen this in action, let's go ahead and use it ourselves. What I'd like you to do is create a new canvas DOM object inside a new div DOM object, that is then put inside the body element. To do this, we're going to have to grab the body element by its id of body.
Next, our key activities. What's the most important things you need to do for the business to make the business model work. Are you in the production business, are you making something, or you're in the problem-solving business like you're doing consulting or engineering or you're managing supply chains.
What makes them tick are the chips inside them.
Obstinacy Hinders Liberation (Moksha) Now the root of obstinacy is Ego (ahamkar). It is on the foundation of Egoism that all of this exists
The one behaving like this, doesn't realize this is what they are doing. They will intentionally behave obstinately. "[I'll] straighten that person out.
If obstinacy alone doesn't work then to show her self-importance (rof) she will throw manipulative tantrums (tragu) [she will] create a ruckus Then [she'll throw] manipulative tantrums (tragu), public complaining (taipho), public fiasco (bhavado) all that will ensue. But in our case it goes up to obstinacy
That is the baggage of obstinacy. And then the mister will not simply straighten up only when he gets a beating, will he straighten up. An obstinate person only becomes straight when he really gets heavily punished.
"You were saying things about me" "I have heard it with my own ears." "That this Dimple [File 1] is useless."
Then we ask, "From which ear did you hear? From the ear that is hearing properly or the deaf ear?"
We are saying something nice about him but with his deaf ear he will hear something otherwise. He may have heard it through the properly working ear but the mind has its own ears. The mind also has ears, it has eyes, it has everything.
So, the first thing we need to know is, what is canvas? Canvas is a new HTML5 element which exposes APls allowing you to draw graphs, images, and text to portions of the page. A canvas only has two attributes specific to it, width and height, which specify what size this drawing surface is on your page.
Yankees, it closely resembles the memory layouts that game developers have been using for years to generate 2D games.
We're asked how many centiliters are in one dekaliter? So the first thing we want to do is just think about how much is a centiliter relative to a liter, and how much is a dekaliter relative to a liter? And I'll write the prefixes down.
Let me write this in a different color. If you have a centiliter, this is equal to 1/100 of a liter, Or you could say 1 liter for every 100 centiliters, so you could also write it like this:
1 dekaliter over here would be the same thing as 10 liters. That's liters. We're assuming that our unit is liters here.
100 deciliters is how many centiliters? Well, 100 deciliters, each of them is going to be worth 10 centiliters, so that's going to be 1,000 centiliters.
1 dekaliter is 1,000 centiliters.
Now, the other way to do it is you could convert a dekaliter to liters, and then convert a liter to centiliters. So if we have one dekaliter-- and whenever you do unit things, just make sure that it makes sense. Sometimes, people, instead of multiplying, they would divide, and then they'd get, oh, 1 dekaliter is equal to 1/1,000 of a centiliter.
So 1 dekaliter is equal to-- these cancel out. 1 times 10 is 10 liters. Now, if we wanted to convert this to centiliters, we're going to want the liters in the denominator, and you want the centiliters in the numerator.
I just did several videos on the binomial theorem, so I think, now that they're done, I think now is good time to do the proof of the derivative of the general form. Let's take the derivative of x to the n. Now that we know the binomial theorem, we have the tools to do it.
How do we take the derivative?
Well, what's the classic definition of the derivative?
Obviously, direct--that would be a direct sales force--number 4. Ancillary would be number 2--referred revenue. An example of an asset revenue stream would be number 6--sale of ownership.
Why do the most startups fail? Is it because co-founders fight and company breaks up? Is it because they can't build their initial spec or vision, or is it that no one will fund the idea, or is it that too few people buy or use the product?
We're asked to write this right here in word form, and I'm not saying it out loud because that would give the answer away. We have 63.15 that we want to write in word form.
There's one common way of doing this, but we'll talk about the different ways you could express this as a word. But we know how to write this stuff to the left. This is pretty straightforward.
And instead of the decimal, we'll write, and. Now there's two ways to go here. We could say, and one tenth and five hundredths, or we could just say, look, this is fifteen hundredths.
Just like that. Now, it might have been a little bit more natural to say, how come I don't say one tenth and then five hundredths? And you could, but that would just make it a little bit harder for someone's brain to process it when you say it.
Sixty-three and one tenth and five hundredths is hard for most people's brains to process. But if you say, fifteen hundredths, people get what you're saying. Not to beat a dead horse, but this right here, this is 1/10 right here and then this is 5/100, 5 over 100.
And the answer is p--is indeed contained within np and the reason is if the problem that we had can be decided by some polynomial time algorithm s that takes the input, runs in polynomial time, and either says yes or no correctly for that input, then we can design-- remember that the main thing in the definition of np is that it has a verification algorithm, so we can define a verification algorithm like this--define a to take the input and any certificate that simply returns s of x--this runs in polynomial time and it accepts inputs and certificates correctly. So for any input x, there's some certificate that makes it say yes--that is to say any certificate-- because if the answer is yes, it's always going to return yes. And if the answer is no, there's no certificate you can give it that would get it to say anything other than no.
So the first thing to observe is that no non-tree edge can be a bridge. They have to be the green edges not the red edges, and why is that? Well, the red edges are the ones that get added for a node that had already been reached by some other path.
Post order of W, the number of descendants of W, and the high and low values and why is that. So when we go to do the post ordering at W, we go it down here, we number somebody, then we number everybody, then we number W itself. The post order number of everyone in here has to be less than the post order of the value of W but the total number of numbers in these set they're all--they're all continuous, they're all in order and the total of numbers--numbers in this set is blue is the number of descendants.
Remember the H value and the L value were defined specifically to be well, you follow a bunch of green edges and then you follow one red edge. Well, if a red edge takes us to in a sort of in the left of this tree, then the in order value is going to be outside of this range and it pretty good will be too small and that we'll tell us that we've link to something outside to the left. If we link to something outside to the right then the H number is going to be bigger than the in order value of W and similarly if we hop up to high that same thing happens it's because that the blobs in here, the nodes in this blob all have exactly the values in here.
Another category of graphs that are very important and come up a lot are planar graphs. These are graphs that can be drawn in the plane on a flat piece of paper so that the edges don't cross. Here's an example of a planar graph.
So, we've been going through all of the others things that we were assuming are held constant in order to be moving along one demand curve. And now let's list a few other[s]. And before I do any more of them,
[WRlTING] Demand goes up. And remember ... when demand goes up, we're talking about the whole curve shifting to the right.
Welcome back. We're ready to do part D, and let me copy and paste that in as well.
See, I don't think that's going to need this graph, so let me just remove that with a color other than yellow.
It's copy and pasted. I don't know if you can read it, but it's helpful for me to review the problem on our clipboard. OK.
Based on the model, how many tickets were sold by 3:00 PM? So my t equals 3-- to the nearest whole number? So that's sometimes important.
[UNlNTELLlGIBLE]
So let's say the tickets sold as a function of time is going to be equal to the definite integral-- well, we could say is at any time t, the tickets sold-- and this is the fundamental theorems calculus, I think it might be one of its correlaries or actually sometimes it is the fundamental theorem of calculus, I always forget my definitions. Between time equals 0 and t-- or if we want to know the tickets sold, between time equals 0 and t is equal to the integral of the rate at which the tickets sold was changing. So that's equal to 550te to the minus t over 2dt.
So we say 973 tickets sold by 3:00 PM. And we're done. That only took us four minutes.

Welcome to the presentation on adding decimals. Let's do some problems. So let's say I had point zero zero eight-- that's an eight-- five plus-- and I'm writing it side by side on purpose-- one point seven nine nine.
Point zero zero eight five. Now for the second number let's put the decimal point right below where that first decimal is on the top number, and then rewrite the number.
Five plus zero is five.
Eight plus nine is seventeen.
One plus zero plus nine is ten. Carry the one.
One plus zero plus seven is eight. And then bring down this one because there's nothing to add it to. And we could have even added a leading zero here if you wanted to.
Fifty-eight point seven five plus point zero two eight. Now if you saw a problem like this, written in this format, your temptation might be to immediately start adding.
Add the five to the eight, the seven to the two, the eight to the zero. And then just bring down the five or something of that nature. And you would be wrong.
Fifty-eight point seven five. And now let's rewrite the bottom number so that the decimal points line up. So we'll put the decimal points right below it.
Zero plus eight is eight. Five plus two is seven. Seven plus zero is seven.
Five plus blank space is five. And we just drop down that decimal point, and we're done. It's that straightforward.
Fifty-eight and three fourths. And I'm adding a very small number to it. I'm adding point zero two eight.
One hundred two point one plus two point five six, that should be like one hundred four point something. I won't do it in my head. We'll do it on paper.
One hundred two point one plus-- line up the decimal points-- two point five six. Now we could add a trailing zero here and we're ready to add. Zero plus six is six.
One plus five is six. Two plus two is four. Zero plus nothing is zero.
One hundred four point sixty-six. It was that easy. Hopefully it's easy.
Now we're going to use Euler's formula to give us a handle on how fast edges grow relative to the number of nodes in a planar graph. We're going to make use of two other facts. One is that every region in a planar graph has to be encapsulated--has to be bounded-- by at least three edges for it to be a region.
We have the function f of x is equal to x minus 1 squared minus 2. And they've constrained the domain to x being less than or equal to 1. So we have the left half of a parabola right here.
We know it's for x is less than or equal to 1. But right now we have y solved for in terms of x. Or we've solved for y, to find the inverse we're going to want to solve for x in terms of y.
Solve for x and make sure you keep track of the domains and the ranges. So, let's see. We could add 2 to both sides of this equation.
Because now it's not clear what we're -- whether x is the domain or the range. But we know by the end of this problem, y is going to be the domain. So let's just swap this here.
So, for y is greater than or equal to negative 2. And we could also say, in parentheses, x is less than 1. This is -- we haven't solved it explicitly for either one, so we'll keep both of them around right now.
So because this expression is negative and we want to get back to this expression, we want to get back to this x minus 1, we need to take the negative square root of both sides. You can always -- every perfect square has a positive or a negative root. The principle root is a positive root.
-- and I'll just write this extra step here, just so you realize what we're doing. Is equal to the negative square root, the negative square root of x minus 1 squared. For y is greater than or equal to negative 2.
For this problem we have 6 graphs, and we want you to order them with a clustering coefficient of the red node of each graph. Order them from the lowest clustering coefficient to the highest clustering coefficient. For example, if you think f has the lowest clustering coefficient put that first and then maybe b, e, a, c, d.
Attachment For Children Our topic for today is,
"Attachment (moha) for children"
On this topic...
This moha for children,
is what we will have to see in Gnan. If we want to go to moksha, let alone the moha for others but we will also have to come out of the moha for our own self!
But for those who have the moha, they will say, "Of course I need [children]." If we have already got them [children] before this understanding, then check for the moha [for children]. How far-stretched and deep is our moha....
From the time the baby boy is born...let alone the birth, in-fact from the time they come to know of the pregnancy, both the mother and father get attached [to the baby]. From within they become happy, happy, happy, happy... They just don't realize that this is our moha.
The veils of ignorance over the Self are so dense, If one does not have this Gnan then we don't even tell them that that you don't even realize that this (attachment) is a mistake, we realize that, this is the way it is [for them].... But even after Gnan,
[the belief] that, "he is mine, mine, mine, mine, mine" is wound up countless times,
then when he [our child] does not do as we say then the botheration starts there
We have no problem as long as he goes along as per our say. At that time, the [the strings] of moha are wound even more it [moha] becomes even stronger. but when they stop listening to us, then from then on the internal suffering bhogwato starts And yet, the moha does not go!
There is no need to bring vairaag but at least an understanding should arise in opposition to this moha.
Just like Smita (name of a Mahatma) said this morning, that just within 2 days she felt a remarkable change. When the children were in a mountain of sadness, we [parents] feel so sad that, oh on, now [my child] will remain in this state for her whole life. And then we become so disheartened that we try to do this for her and do that for her we try to give her happiness in various ways.
Do your drama; be there for her when she needs you, but there is no need to cry when she cries!
Do you understand Smita?
we are joint [with the child] with the cord of moha that is why we feel this way it [the cord] is of moha - moha!
There is so much moha, so much moha for the children that it can also exceed that for the husband!
When the children get a little older then [the mother] sides with not the husband but with the children. By getting the children on her side, they make a "gang", a stronghold. And he [the husband] remains alone (helpless)!
And he keeps on pinning and languishing, "Gosh, I had so much value, I work so hard, I do so much for everyone and yet I am alone, without a side!
And if one of them makes a mistake, from the gang of four, say if one of them makes a mistake, then all four will cover up for each other, they will get together and cover up the mistake. Therefore none of the "gang" members gets caught... Look - All the men are saying "Yes"
Even then he [husband] does not feel vairag, that, "Let me leave them [family] and go to the jungle." Because he cannot stay without her [the wife's] lentil soup and her [the wife's] chutney of sensual pleasures (vishay)! That does not allow him to leave her.
Now that we have this Gnan, so we do not have to leave anything, and with this Gnan we don't have to take beatings either!! If we remove this moha then pure love (prem) will come, the atmosphere will become one of prem. After Gnan, if the reign of moha goes, then it gives way to the reign of prem.
The mistake is not of the children but of the parents! 85% of the mistake is of the parents. The beatings are taken due to their moha.
So parents need to keep this balance. The parents need to learn all these lessons. Before becoming parents, one needs to attend a course at a college on how to be ideal father and mother!
Therefore every now and then differences will occur. every now and then differences occur. After they come of a certain age, after they turn 18 years of age, to try and improve them to be like this or like that, in-fact leave alone 18 but when they turn 16, just talk to them in a friendly manner. Forget the urge to improve them, also forget even the urge to guide them.
So go with the awareness, See this in the samayik - now we are beginning the samayik. Check in samayik how much moha we have for our children.
There can be [progress] only through absolute detachment (vitraagta), where there is attachment we cannot progress [to moksha] If we [Niruma] were attached to any of these boys [in Adalaj] with moha, e.g. Sanjay or Dimple or Deepakbhai, then it means that we have come under their control!
Friends, today we have forgotten to even play today we just watch things, we watch games we don't play, cinema/films have become something to watch even if we talk about play, which became cinema theater play, its base was also play humans used to play different things and enjoyed it today we don't play and enjoy win-loss has come in that like if we look at our sports, we removed over limitations from cricket it was a 7 day play earlier it became 5 days and now it came to 20-20 meaning, today's win-loss world can be seen every where you can see it it in football too when humans started creating dramas we started writing stories then we started acting then slowly from that play came out when technology is advanced cinema came out and cinema killed people's creativity today we just watch cinema making of it, being a part of it or directing it thinking about it all the fun we have ignored so we are trying it with chamba have complete fun making play, making cinema in which there won't be a single director nor a single screenplay writer everyone will contribute with whole of their skills like when children play, after an hour of play they won't make a calculation like this - what did I gain after an hour? we are making a film like that with chamba
Find the value of 5 to the third power. Let me rewrite that. We have 5 to the third power.
Let's say I have this bizarre-looking function. It's just some arbitrary function. And we'll call that f of x.
Hi, my name is Jeff Law and I'm from Haas Automation I am going to talk today about our new Program Optimizer function Oftentimes I write a CNC program at my desk and I bring it down to the machine to debug the program while I set up the first part
P-Cool nozzle positions, so on and so forth, those changes are all captured If I want to write a comment to myself, I simply feed hold the machine type the comment, press the [WRlTE / ENTER] key and cycle start to resume cutting, and that change is captured as well
Now that I've run the first part and made my override changes I can incorporate those changes back into the CNC program using the optimizer window To get to the optimizer window, I press the [F4] key
So, in this video, we're going to start reasoning about the performance of hash tables.
Finally all these adds up on the left hand side over here to cost. What are the cost and expenses to operate the business model? One of the interest thing things about cost is it's not just the obvious ones
About 10 years ago, I took on the task to teach global development to Swedish undergraduate students. That was after having spent about 20 years together with African institutions studying hunger in Africa, so I was sort of expected to know a little about the world. And I started in our medical university, Karolinska Institute, an undergraduate course called Global Health.
I did also an unethical study of the professors of the Karolinska Institute, that hands out the Nobel Prize in Medicine, and they are on par with the chimpanzee there. (Laughter) This is where I realized that there was really a need to communicate, because the data of what's happening in the world and the child health of every country is very well aware.
Because my students, what they said when they looked upon the world, and I asked them, "What do you really think about the world?" Well, I first discovered that the textbook was Tintin, mainly.
And 'we' is Western world and 'them' is Third World." "And what do you mean with Western world?" I said.
"Well, that's long life and small family, and Third World is short life and large family." So this is what I could display here. I put fertility rate here: number of children per woman: one, two, three, four, up to about eight children per woman.
So we started a nonprofit venture which, linking data to design, we called Gapminder, from the London Underground, where they warn you, "mind the gap." So we thought Gapminder was appropriate. And we started to write software which could link the data like this.
Everyone says, "It's impossible. This can't be done. Our information is so peculiar in detail, so that cannot be searched as others can be searched.
(Laughter) So we can see a lot happening in data in the coming years. We will be able to look at income distributions in completely new ways.
Almost like a ghost, isn't it? (Laughter) It's pretty scary.
The really important property of heaps is at the smallest value of all has to be at the top. Why is that? Because a node can't be below anything larger than that.
This means, "I'm smiling." So does that. This means "mouse."
"Honestly, geez, what are my chances?" (Laughter)
And he could say, "Oh my God!" or "I heart you!"
"I'm laughing out loud."
"I want to give you a hug." But he comes up with that, you know.
He tells her, "I'd like to hand-paint your portrait on a coffee mug." (Laughter)
Put a crab inside it. Add some water. Seven different salts.
I'm a monkey -- (Laughter) -- blowing kisses at a butterfly. But I'm still suggesting you and I should meet. First, soon, and then a lot.
I got a pencil you can borrow.
You can put it in your phone." But the girl does not budge, does not smile, does not frown. She just says, "No thank you."
[ "i don't need 2 write it down." ] (Applause)
We're asked to find the square root of 100. Let me write this down bigger. So the square root is this big check-looking thing.
I'm here to share my photography. Or is it photography? Because, of course, this is a photograph that you can't take with your camera.
Okay. What I'd like to do here is work out what the general rule is. Imagine that we've got some node and say it's numbered i.
Welcome to the greatest common divisor or greatest common factor video. So just to be clear, first of all, when someone asks you what's the greatest common divisor of twelve and eight? Or they ask you what's the greatest common factor of twelve and eight?
Three goes into twelve.
Four goes into twelve.
Five does not to go into twelve. Six goes into twelve because two times six. And then, twelve goes into twelve of course.
One times twelve. So that's the factors of twelve. Let's write the factors of eight.
Well, one goes into eight. Two goes into eight. Three does not go into eight.
Four does go into eight. And then the last factor, pairing up with the one is eight. So now we've written all the factors of twelve and eight.
Greatest common factor of twelve and eight equals four. And of course, we could have just as easily had said, the greatest common divisor of twelve and eight equals four. Sometimes it does things a little funny.
What is the greatest common divisor of twenty-five and twenty? Well, let's do it the same way.
The factors of twenty-five? Well, it's one.
Two doesn't go into it. Three doesn't go into it. Four doesn't go into it.
Factors of twenty are one, two, four, five, ten, and twenty. And if we just look at this by inspection we see, well, they both share one, but that's nothing special. But they both have the common factor of?
What is the greatest common factor of five and twelve?
Well, factors of five? Pretty easy.
One and five. That's because it's a prime number. It has no factors other than one and itself.
Twelve has a lot of factors. It's one, two, three, four, six, and twelve. So it really looks like only common factor they share is one.
Let's do the greatest common divisor of six and twelve. I know twelve's coming up a lot. I'll try to be more creative when I think of my numbers.
Factors of twelve: one, two, three-- we almost should have these memorized by now.
Three, four, six, and twelve.
Well, it turns out one is a common factor of both.
Two is also a common factor of both.
Three is a common factor of both. And six is a common factor of both. And of course, what's the greatest common factor?
Using the same bipartite graph, B, with 5 edges on the left and 3 edges on the right we ask what is the maximum possible path length in B?
This is a work in process, based on some comments that were made at TED two years ago about the need for the storage of vaccine.
(Music) (Video) Narrator:
On this planet, 1.6 billion people don't have access to electricity, refrigeration or stored fuels.
This is a problem.
It impacts:
the spread of disease, the storage of food and medicine and the quality of life.
So here's the plan: inexpensive refrigeration that doesn't use electricity, propane, gas, kerosene or consumables. Time for some thermodynamics. And the story of the Intermittent Absorption Refrigerator.
Now, a simple way for you to start with your customer segment hypotheses is rank each job according to what you believe is its significance to the customer. And you get to guess on day 1 is it crucial or trivial? And take a guess about how frequently it occurs, and outline what specific context a job gets done.

This right here is a picture of an Airbus A380 aircraft, and I was curious
How long would it take this aircraft to take-off? And I looked up its take-off velocity, and the specs I got were 280 km/h.
And to make this a velocity, we have to specify a direction as well, not just a magnitude. So the direction is in the direction of the runway. So that would be the positive direction.
"We're taking off" to when it actually takes off, it has a constant acceleration. Its engines are able to provide a constant acceleration. Acceleration of 1.0 m/s per second
1.0 m/s^2 I find this a little bit more intuitive, a little bit neater to write. So let's figure this out.
Or what do we put in front of the 'hours' and 'seconds'? So in 1 hour there are 3600 seconds. 60 seconds in a minute, 60 minutes in an hour
The 'hours' will cancel out. And we'll get 280 divided by 3600 kilometers per second. But I want to do all my math at once, so let's also do the conversion from kilometers to meters.
100 is what percent of 80? These problems tend to kill people because on some level they're kind of simple, they're just 100 and an 80 there, and they're asking what percent. But then people get confused.
The 80 by 100? Or is it something else going on? And you really just have to think through what the
We have 80. If we multiply it by something, let's call this something x. Let me do that in a different color.
And if we just solve this equation as it is, we're going to get a value for x. And what we need to do is then convert it to a percent. Another way you could have viewed this is 100 is what you get when you multiply what by 80?
1 times 4 is 4. You subtract. You get 5 minus 4 is 1.
4 goes into 10 two times.
2 times 4 is 8. You subtract.
10 minus 8 is 2.
Bring down the next zero. 4 goes into 20 five times.
5 times 4 is 20. Subtract. No remainder.
5/4 is the same thing as 5 divided by 4, which is equal to 1.25. So far, we could say, 100 is 1.25 times 80, or 1.25 of 80, you could even say, But we still haven't expressed it as a percentage. This is really just as a number.
100 is 125% of 80.
80 is 100% of 80.
100% percent is more than 80. It's actually 1 and 1/4 of 80, and you see that right over there, so it makes sense. It's 125%.
 Let's try to subtract 659 from 971. And as soon as you start trying to do it, you face a problem.
In the example, we're just talking about with the marvel comic book characters, the strength of the link between some character i and some character j was the number of comic books they appeared in together. Now, this is an actually very useful metric for real life social networks. I have not appeared in any comic books with anyone.
The story I wanted to share with you today is my challenge as an Iranian artist, as an Iranian woman artist, as an Iranian woman artist living in exile. Well, it has its pluses and minuses.
Now comes the green movement -- the summer of 2009, as my film is released -- the uprising begins in the streets of Tehran. What is unbelievably ironic is the period that we tried to depict in the film, the cry for democracy and social justice, repeats itself now again in Tehran. The green movement significantly inspired the world.
The standard question you often get in your algebra class is they will give you this equation and it'll say identify the conic section and graph it if you can. And the equation they give you won't be in the standard form, because if it was you could just kind of pattern match with what I showed in some of the previous videos and you'd be able to get it. So let's do a question like and let's see if we can figure it out.
And let's do the y terms in magenta. So then you have plus 4y squared minus 8y and then you have-- let me do this in a different color-- plus 49 is equal to 0. And so the easy thing to do when you complete the square, the thing I like to do is, it's very clear we can factor out a 9 out of both of these numbers, and we can factor out a 4 out of both of those.
So this is the same thing is 9 times x squared plus 9 times 6 is 54, 6x. I'm going to add something else here, but I'll leave it blank for now.
Remember it's an equation, so what you do to one side, you have to do to the other. So if we added a 9 here, we're actually adding 9 times 9 to the left-hand side of the equation, so we have to add 81 to the right-hand side to make the equation still hold. And you could kind of view it if we go back up here.
And now we are getting close to the standard form of something, but remember all the standard forms we did except for the circle-- we had a y-- and we know this isn't a circle, because we have these weird coefficients, well not weird but different coefficients in front of these terms. So to get the 1 on the right-hand side let's divide everything by 36. If you divide everything by 36, this term becomes x plus 3 squared over see 9 over 36 is the same thing as 1 over 4, and then you have plus y minus 1 squared 4 over 36 is the same thing as 1 over 9 and all of that is equal to 1.
What x value makes this whole terms 0? So it's going to be x is equal to minus 3, and y is going to be equal to 1. What y value makes this term 0? y is equal to 1.
Remember you have to take the square root of both of those. The vertical axis is actually the major radius or the semi-major axis is 3, because that's the longer one. And then the 2 is the minor radius, because that's the shorter one.
Simplify: negative one times this expression in brackets negative seven plus 2 times 3 plus 2 minus 5 in parentheses, squared.
So this is an order of operations problem, and remember in order of operations, you always wanna do parentheses first.
We're asked to compute 4,800, or four thousand eight hundred, divided by 80, and then they want us to check our answer, or they say check your answer. So I'll first do it just the traditional long division way, and then we'll think about if there's maybe a faster way to do this or if we can even do it in our heads. So let's just do it the traditional way first.
6 times 0 is 0. 6 times 8 is 48.
Or another way you could have thought about it is 6 times 8 is 48, and we have this extra 0 here, so you add the 0 right there. So 80 goes into 480 six times, because we're only considering the 480. We put the 6 right in 480's one spot, which is really the tens place, but if you just think about the 480, it's right above the zero.
0 times 80 is 0. You subtract. You get zeroes, and there's nothing left to bring down, so we're done.
This is dividend.
Then our quotient is 60. Now they want us to check our answer, so we just have to confirm that 60 times 80 is 4,800 so let's do that.
60 times 80-- now there's two ways you can do it. You could just literally say 6 times 8 is 48, and then it'll have two zeroes here, one, two. That's 4,800.
0 times 0 is 0.
0 times 6 is 0. Then we'll put a zero here because we're now in the tens spot. Put the zero here.
8 times 6 is 48. Add all of this up. You get 4,800, so it works.
4,800/80 could be written as 480 times 10 over 8 times 10. 4,800 is just 480 times 10, and 80 is just 8 times 10. Now what happens here?
6 times 8 is 48. You have no remainder. Bring down this zero.
One of the other interesting observations about customer development is this notion of the pivot. The pivot was a term that my best student ever Eric Reese coined when he noticed the arrow between customer validation and customer discovery, and he actually gave it a name, which I think is incredibly accurate. A pivot says what do you do when your hypotheses don't meet reality?
"Our revenue model shouldn't be freemium." "We should be charging for it from day 1," or "Wait a minute."
"We've been using the wrong distribution channel." "We need a direct sales force," or "Gee, we have the wrong partners." By the way, an iteration is a minor change to one or more of the business model components.
Let's take a look at Euler's formula again. What we're going to do is prove by induction that this holds. We can build any planar graph by iteratively adding nodes and edges.
I've been working on issues of poverty for more than 20 years, and so it's ironic that the problem that and question that I most grapple with is how you actually define poverty. What does it mean? So often, we look at dollar terms -- people making less than a dollar or two or three a day.
So let's write some Python code to solve this particular example. So here's a translation of that problem and the solution into Python. So first I have a list of the connections in that graph we were just looking at--nodes A through H.
In summary, partnering strategies are great. But understand you're not a peer of these large companies. And all the books and literature that talks about partnerships very rarely addresses startup to large company partnerships.
>> Now let's take a little deeper look at what is contained inside of the data array. Now, if you recall, each layer is actually a large two-dimensional grid of tile data. It's listed here in the JSON file as a single integer array.
Welcome to the presentation on level four division. So what makes level four division harder than level three division is instead of having a one-digit number being divided into a multi-digit number, we're now going to have a two-digit number divided into a multi-digit number. So let's get started with some practice problems.
Zero times twenty-five is zero. Remainder is zero. So we see that twenty-five goes into six thousand two hundred fifty exactly two hundred fifty times.
And since you don't know two-digit multiplication tables-- very few people do-- you have to do a little bit of guesswork. Sometimes you can look at this first digit and look at the first digit here and make an estimate. But sometimes it's trial and error.
In her interview, Tina mentioned the concept of homophily. What is homophily? Is it the observation that two words tend to be pronounced similarly if they're in a social network?
As an Indian, and now as a politician and a government minister, I've become rather concerned about the hype we're hearing about our own country, all this talk about India becoming a world leader, even the next superpower. In fact, the American publishers of my book,
"The Elephant, The Tiger and the Cell Phone," added a gratuitous subtitle saying,
"India: The next 21st-century power." And I just don't think that's what India's all about, or should be all about.
Well, we have now the fifth-largest economy in the world in purchasing power parity terms. When the rest of the world took a beating last year, we grew at 6.7 percent.
The Beijing Olympics were an exercise in Chinese soft power. Americans have the Voice of America and the Fulbright scholarships. But, the fact is, in fact, that probably Hollywood and MTV and McDonalds have done more for American soft power around the world than any specifically government activity.
(Laughter) If you then wanted to connect to another city, let's say from Calcutta you wanted to call Delhi, you'd have to book something called a trunk call, and then sit by the phone all day, waiting for it to come through.
Or you could pay eight times the going rate for something called a lightning call. But, lightning struck rather slowly in our country in those days, so, it was like about a half an hour for a lightning call to come through. In fact, so woeful was our telephone service that a Member of Parliament stood up in 1984 and complained about this.
(Laughter) I usually tend to think that the book is usually better, but, having said that, the fact is that Bollywood is now taking a certain aspect of Indian-ness and Indian culture around the globe, not just in the Indian diaspora in the U.S. and the U.K., but to the screens of Arabs and Africans, of Senegalese and Syrians. I've met a young man in New York whose illiterate mother in a village in Senegal takes a bus once a month to the capital city of Dakar, just to watch a Bollywood movie.
"Kyunki Saas Bhi Kabhi Bahu Thi," dubbed into Dari, was telecast on Tolo T.V. And it was the most popular television show in Afghan history. Every Afghan family wanted to watch it.
Crime went up at 8:30. I have read a Reuters dispatch -- so this is not Indian propaganda, a British news agency -- about how robbers in the town of Musarri Sharif* stripped a vehicle of its windshield wipers, its hubcaps, its sideview mirrors, any moving part they could find, at 8:30, because the watchmen were busy watching the T.V. rather than minding the store. And they scrawled on the windshield in a reference to the show's heroine,
"Tulsi Zindabad": "Long live Tulsi." (Laughter)
And that is what India is developing through the "E" part of TED: its own entertainment industry. The same is true, of course -- we don't have time for too many more examples -- but it's true of our music, of our dance, of our art, yoga, ayurveda, even Indian cuisine. I mean, the proliferation of Indian restaurants since I first went abroad as a student, in the mid '70s, and what I see today, you can't go to a mid-size town in Europe or North America and not find an Indian restaurant.
(Applause) But, with this increasing awareness of India, with you and with I, and so on, with tales like Afghanistan, comes something vital in the information era, the sense that in today's world it's not the side of the bigger army that wins, it's the country that tells a better story that prevails. And India is, and must remain, in my view, the land of the better story.
"You're Indian, you're Indian! Can you help me fix my laptop?"
(Laughter) We've gone from the image of India as land of fakirs lying on beds of nails, and snake charmers with the Indian rope trick, to the image of India as a land of mathematical geniuses, computer wizards, software gurus.
(Applause) That's the Indian story. Islam came peacefully to the south, slightly more differently complicated history in the north.
(Applause) This is India, and of course it's all the more striking because it was four years later that we all applauded the U.S., the oldest democracy in the modern world, more than 220 years of free and fair elections, which took till last year to elect a president or a vice president who wasn't white, male or Christian. So, maybe -- oh sorry, he is Christian, I beg your pardon -- and he is male, but he isn't white.
(Laughter) All his predecessors have been all those three, and that's the point I was trying to make.
(Laughter) But, the issue is that when I talked about that example, it's not just about talking about India, it's not propaganda. Because ultimately, that electoral outcome had nothing to do with the rest of the world.
(Applause)
We're on problem 38. Which of the following best describes the graph of this system of equations? OK, so maybe they're the same line.
So if you multiply the top equation-- both sides of it-- by 5 and it really doesn't fundamentally change the line, the equation might look different, but the equality will still hold in the same universe, which is essentially that line. So if you just multiply both sides by 5, they become the same equation. 5y is equal to minus 10x plus 15.
Let's take a look at keeping customers for the web/mobile channel. Web/mobile works almost exactly like physical channels--keeping customers. It's exactly the same idea--we might want to offer loyalty programs, contests and events, blogs, RSS and email, or social media--all designed to engage customers.
Do you ever feel completely overwhelmed when you're faced with a complex problem? Well, I hope to change that in less than three minutes. So, I hope to convince you that complex doesn't always equal complicated.
Let's multiply 4 times 2012. Actually, let's make it a little bit simpler, let's multiply 4 times 201. Just to simplify things a little bit.
So what's the relation between -x and -5?
And when I say, what's the relation, is it greater than or is it less than -5?
Well, 6 is a value that works for x, so -6, is that greater than or less than -5? -6 is less than -5, right? So let me draw the number line here.
Here we got X is less than or equal to negative 1/3
Now we can subtract 7 from both sides,
-13x > -5. Now we're gonna divide both sides of this equation by -13. Well, very easy.
To understand the business of mythology and what a Chief Belief Officer is supposed to do, you have to hear a story of Ganesha, the elephant-headed god who is the scribe of storytellers, and his brother, the athletic warlord of the gods, Kartikeya. The two brothers one day decided to go on a race, three times around the world.
"You went around 'the world.' I went around 'my world.'" What matters more?
'The world' is objective, logical, universal, factual, scientific.
'My world' is subjective. It's emotional. It's personal.
'The world' tells us how the world functions, how the sun rises, how we are born.
'My world' tells us why the sun rises, why we were born. Every culture is trying to understand itself:
"Why do we exist?" And every culture comes up with its own understanding of life, its own customized version of mythology. Culture is a reaction to nature, and this understanding of our ancestors is transmitted generation from generation in the form of stories, symbols and rituals, which are always indifferent to rationality.
"I'm experiencing nothingness." Then the gymnosophist asked,
"What are you doing?" and Alexander said, "I am conquering the world." And they both laughed. Each one thought that the other was a fool.
"Why is he sitting around, doing nothing? What a waste of a life." To understand this difference in viewpoints, we have to understand the subjective truth of Alexander -- his myth, and the mythology that constructed it.
"Achilles was a man who could shape history, a man of destiny, and this is what you should be, Alexander." That's what he heard.
"What should you not be? You should not be Sisyphus, who rolls a rock up a mountain all day only to find the boulder rolled down at night. Don't live a life which is monotonous, mediocre, meaningless.
"I was here first." But when he reached the mountain peak, he found the peak covered with countless flags of world-conquerors before him, each one claiming "'I was here first' ... that's what I thought until I came here." And suddenly, in this canvas of infinity,
And I believe it is this mythological paradigm that inspired Indian mathematicians to discover the number zero. Who knows? And that brings us to the mythology of business.
But if you look at cultures which have cyclical and based on infinite lives, you will see a comfort with fuzzy logic, with opinion, with contextual thinking, with everything is relative, sort of -- (Laughter) mostly. (Laughter) You look at art.
"All I want to do is align belief." Sounds so simple. But belief is not measurable.
"Just know where I came from, why I did the Jugaad." (Laughter)
"Why did I do the setting, why I don't care for the processes. Just understand me, please." And based on this, we created a ritual for leaders.
Good day, viewers. In this segment, I'll go over a brief overview of the Link Layer to remind you where we are in the course and what we're going to cover this week. Okay.
Welcome to the presentation on subtracting decimal numbers. Let's get started with some problems. The first problem I have here says five point seven three minus point zero eight two one equals who knows?
Decimal zero eight two one. And some people say it's good to always put a zero in front of the decimal. My wife's a doctor and she says it's critical otherwise you might give someone the wrong amount of medicine.
Well ten is larger than one, nine is larger than two, two is not larger than eight. So we have to borrow again. So if we're going to borrow, the two becomes a twelve, and the seven-- we borrowed one from that -- becomes a six.
Ten is larger than one, nine is larger than two, twelve is larger than eight, six is larger than zero, and five is larger than zero. So now we've done all of our borrowing and we're ready to do some subtraction, and this is the easy part.
Ten minus one is nine. Nine minus two is seven.
Twelve minus eight is four.
Six minus zero is six.
Five minus zero is five. And we just bring down the decimal point. So there's our answer.
Five point seven three minus zero point zero eight two one is equal to five point six four seven nine. There you go. I probably confused you, so let's do some more problems.
Eight -- let me leave some space on top to do the borrowing.
Eight point two five minus zero point zero one zero five. So what was that first step that I always have to do? Right.
Ten is larger than five.
Nine is larger than zero.
Four is larger than one.
Two is larger than zero.
Eight is larger than zero. So I think I'm ready to subtract.
Ten minus five, well that's five.
Nine minus zero is nine. Four minus one is three. Two minus zero is two.
Two point six four and it's point zero four eight six. Lined up the decimal points, include the zeros on top. You're going to have a zero here, so I have to borrow.
Can't borrow from the zero, so I have to borrow from this entire forty. So this forty becomes a thirty-nine. I think I'm running out of space.
Nine is larger than eight.
Three is not larger than four. So this three I'm going to have to borrow. So three becomes a thirteen.
The thirteen is larger than four, and five is larger than zero. So we're ready to subtract.
Ten minus six is four.
Nine minus eight is one.
Thirteen minus four is nine.
Five minus zero is five.
Two minus nothing is two. Bring down the decimal point. So two point six four minus point zero four eight six is equal to two point five nine one four.
Thousands of open source contributors have worked for over 3 years to bring you Drupal 7, the most flexible and easy-to-use version of Drupal ever. Drupal already runs hundreds of thousands of websites, including some you probably already know.
Now that you've simulated and simulated the down heapify algorithm on an example and you've seen what the code looks like, tell me what the running time of down heapify would be if you have the heap of size n where the top node might be violating the heap property but it satisfied everyone else. We run down heapify on this and re-establish the heap property and it takes how long?

Or we could write this as 63 over 1 newspapers per hour.
Or we could write this as 63, because 63 over 1 is the same thing as 63 newspapers per hour.
In its most popular sense, when people talk about mitosis, they're referring to a cell, a diploid cell. So diploid just means it has its full complement of chromosomes, so it has 2N chromosomes. So that's the nucleus.
So let's say that at the beginning of S phase, and I'll draw things as chromosomes just to make it clear that things are being replicated. So let me say it has this chromosome right here and then let's say it has this chromosome right here.
During S phase, our chromosomes will replicate and will have-- so that green one will completely replicate and generate a copy of itself, and we've learned this a little bit, they're connected at the centromere. Now, each of those copies are called chromatids, and that magenta one will do the same thing. Even though we have two chromatids, one for each chromosome, now we have four chromatids, two for each chromosome, we still say we only have two chromosomes.
It gets bigger, and that's during the G2 phase, so it's just growing more. Now, there's another little part of the cell we haven't even talked about yet, but I'll talk about it a little bit. It's not super-duper important, but it's the idea of these centrosomes.
But the reality is when we're sitting in the interphase, this is not what the DNA would actually look like. The DNA, if I were to actually draw this, it's in its chromatin form. It's not all tightly wound like I drew it here.
So you have all of these things, and they're connecting the-- you know, some of them are coming from this centrosome, some are coming from this centrosome, some are connecting the two. And then some of these microtubules, these tubes or these ropes, however you want to view them, attach themselves to the centromeres of the actual chromosomes, and the protein structure that they attach them to is called the kinetochore. So there's the kinetochore there, and that may or may not be-- kinetochore.
The centrosomes are these structures that help direct what happens to these microtubules.
Centrioles are these little structures, these little can-shaped structures inside the centrosomes, and the centromere are the center points where the two chromatids attached to each other within a chromosome. So this is one sister chromatid, that's another sister chromatid, and they attach at the centromere. But this is metaphase.
Metaphase, you just have this aligning of the cells, and there's actually some theories, how does the cell know to progress past this point? How does it know that everything is aligned and attached? And then there are some theories that there's actually some signaling mechanism that if one of these kinetochore proteins isn't properly attached to one of these ropes, that somehow a signal is sent that mitosis should not continue.
The answer is--is having a customer archetyping might is really important for all of these-- To know who to talk to during customer development, to determine how to actually sell the market to these customers--they'll tell you if you ask them. To guide how you form hypothesis during product development, and to help define the minimum viable product.
what does it mean by saying this is the last life after this is moksh freedom, moksh means freedom or liberation what is the bondage? please understand that what is the bondage in your life body. what else? no those are secondary. only because you are attached to your body you are attached to somebody. please see that if you are not attached to this body you will not be attached to anybody. it's not possible only because of your attachment to this body you're getting attached to other bodies you say my family the only thing that you know actually about them is their body, please see because it's only from your attachment to your body that is happening you know a little bit of their emotion and thought but that is only in reflection of the body, please see. the fundamental is the body isn't it isn't it so? the most fundamental is body please see today the deepest attachment between people come in man woman relationship, isn't it? why? because of the body where bodies are touching has become the deepest attachment isn't it? this is simply because right now people are existing as body for them truly opening up to somebody means opening up the body nothing else because they cannot open up anywhere else. what else they can open? not really....mind is never open people are talking about open mind there is no such thing. mind is a closed end always they believe it's open for comforts sake tell me how will you open your mind tell me how will you open your mind how will you become silent? no. these are all ways of really closing your mind the people who believe they are very honest, very sincere, please see they are very closed in many ways the so-called good people they believe they are very open. they always claim I am an open book the thing is everything that they know, they've opened to others they don't know much about themselves they have not even opened the book to themselves how can they open it to somebody else? they've not even admitted fundamental facts about life with themselves whatever they have seen they have admitted to other people but they have not even admitted to themselves they can't believe when life really puts them in turmoil and they act in certain ways, good people are always shocked with themselves the so called bad person who is out on the street he has admitted it to himself okay all the nonsense that he is, he's admitted to himself he's not stupid enough to admit it to somebody else he's careful about that but the good person has not even admitted it to himself his own problems his own limitations so he thinks he's an open book the book is not even open to him where is the question of opening it to somebody there is no such thing as an open mind because mind is a closed possibility it is an accumulation, isn't it? what are you going to open in this what are you going to open in this? what is there to see anyway 0:04:12.079,0:04:17.019 you have attached an enormous amount of importance to your mind I know but please look at it sincerely what is there in your mind apart from what you gathered from outside what is there in your mind why should i look into your mind I can look around the world and I know what is there why should i look through the distortion of your mind, isn't it? tell me tell me one new idea no you're very mistaken electricity electricity was always there in your body every moment. your body does not move a limb without electricity. one heart beat does not happen without electricity if you had just looked in, you would know electricity very easily okay you are talking about internet internet has always been there for example
Because the nodes are filled in the tree from top to bottom and left to right, we can number them very naturally as follows. We'll call this node 0, node 1, node 2, node 3, node 4, and so on. Because of the regularity with the way that the nodes are numbered, and the fact that there's always two children until you get down to the bottom and it kind of trails off.
Awareness In The Presence Of Separation Created By The Intellect During Clashes With Individuals Let's do [samayik] on clashes. And here is an excellent discussion.
Between sahadhyayio (spiritual collegues), while doing Dada's work, with sevarthio mahatmas, or during interactions with any persons, If there has been any kind of takaraman (reaction to conflict as clash) then to not to react in the conflict by clashing.
To maintain such an awareness to be able to realize the results of the clashes If bhed (separation) has arisen in the mind
If the intellect had created a rift then [may I] hearty repentant tremendously and eliminate the bhed [that has arisen]. And [may I] set the awareness of separation so that in the conflict,
I may not clash and with prem (pure love) and abhedta (oneness) with the people repair the relationship. For that [grant me the energies]to see in samayik my own faults grant me the energies In each and every worldly interaction,
Here's the answer. The chief financial officer is more than likely the economic buyer. The saboteur might actually be the existing business intelligence group inside of IT or the ClO's department who is actually trying to already build the software, and they might be afraid they're going to lose their jobs, so in every major organization you might find people who actually don't want or actively attempt to block a sale.
The ClO is more than likely the decision maker. In some organizations they can actually sign off on large deals, but in this case the chief information officer is actually going to recommend to the chief financial officer that they buy this software. The report users, the people who actually use the product, in this case they're just simply the influencers, and that's kind of interesting to remember because sometimes those entrepreneurs, we forget that the people who use our product are not necessarily the people who even pay for or even recommend the product, and in this case the recommenders were probably the line of business management, that is, those users worked for a line of business, a division or a department, and the influencers, the people who used it, said to their bosses
"We'd really like to have this software." "This would work great." And their managers, who didn't have any signature authority or couldn't actually install software, recommended that this actually get bought.
Spontaneous Satsangs with Mooji
Let them catch up because he's saying that in these days sitting in Satsang, he's finding that somehow, there is just this feeling of Am-ness; just, to be.
'I can speed this up, maybe I can give more power - I want more power to this.' Yeah? [Questioner:]
But it's like, somehow I feel something primal. Maybe I can... [inaudible]. [M:]
[Q:] So, should I just stay? [M:]
Because nothing I have done... and my life has been a colorful life - you understand? I wasn't brought up in a convent or - no, convent is for girls, no. What is it?
it's like you are...
The ego was not finished. The ego was not finished at this point, not like that. You understand?
And he will still sprout a little bit.
'Hello.' [deflating sound] Every time he came up, he had - something hit [him]. Not I.
Can your ego be blessed? I can say like that. I say the ego can evolve from a tamasic or rajasic state to a very satvic state.
each day you meet; somehow your egoic self comes up. And each day something deeper takes place and there is this [making wave motions] going on. But the overall look of the game?
'Each day you meet your ego-self coming up. And each day something deeper takes place.' ~ Mooji ~ 'Ego is still there but you are doing very well.
Another key resource are people. We sometimes use the fancy word of human resources or HR and I kind of think of people in a start up as two separate categories. One is finding qualified employees.
Let's do some more percentage problems. Let's say that I start this year in my stock portfolio with $95.00. And I say that my portfolio grows by, let's say, fifteen percent.
How much do I have now?
OK. I think you might be able to figure this out on your own, but of course we'll do some example problems, just in case it's a little confusing. So I'm starting with $95.00, and I'll get rid of the dollar sign.
109.25. Notice how easy I made this for you to read, especially this two here. 109.25.
So just like the last problem, I start with x and it grows by twenty-five percent, so x plus twenty-five percent of x is equal to one hundred, and we know this 25% of x we can just rewrite as x plus 0.25 of x is equal to one hundred, and now actually we have a level-- actually this might be level three system, level three linear equation-- but the bottom line, we can just add the coefficients on the x. x is the same thing as onex, right?
Let's see. Let me make the pen thin again, and go back to the orange color, OK. X equals 100 divided by 1.25, so we say 1.25 goes into 100.00-- I'm going to add a couple of 0's, I don't know how many I'm going to need, probably added too many-- if I move this decimal over two to the right, I need to move this one over two to the right.
We're on problem 58. The graph of the equation y is equal to x squared minus 3x minus 4 is shown below.
Fair enough. For what value or values of x is y equal to 0? So they're essentially saying is, when does this here equal 0?
Not minus x squared plus 3, but just x squared plus 3. So if you start with x squared, now every y value for every given x is just going to be 3 higher. So it's just going to shift the graph up by 3.
OK, so they want to know-- let me copy and paste it-- how many times does the graph of y equals 2x squared minus 2x plus 3 intersect the x-axis? So the easiest thing-- because maybe it doesn't intersect the x-axis at all. Maybe if you use a quadratic equation there are no real solutions.
62. An object that is projected straight down-- oh, this is good, this is projectile motion-- is projected straight downward with initial velocity v feet per second, Travels a distance of s v times t plus 16t squared, where t equals time in seconds. If Ramon is standing on a balcony 84 feet above the ground and throws a penny straight down with an initial velocity of 10 feet per second, in how many seconds will it reach the ground?
25 plus-- let's see. 4 times 8 times 42. That's 32 times 42.
1,369 over 16. And actually, I don't know what the square root of 1369 is. Let me get the calculator.
Accessories, calculator. All right. So 1,369.
Minus 5 minus 37 over 16. We don't want a negative time, we want a positive time. So let's just do the positive.
Minus 5 plus 37 over 16. So that's 32/16, which equals to 2 seconds. And that's choice A.
This is Revolution 2.0. No one was a hero. No one was a hero.
"Enough. Get those who killed this guy. To just bring them to justice."
Now we can look at this as a decision problem and we'll call it the long and simple path decision problem and it goes like this.
Given a graph G and a link L and two nodes U and V, is there a simple path from U to V consisting of L or more nodes? We're not looking for a short path, we're actually looking for a long and simple path, and we're going to imagine and I'm saying imagine because I actually don't know whether this is true or not, but we're going to imagine that there is an algorithm that solves this decision problem, yes or no correctly, and its running time is n to the k for some constant k like two.
Θ(n²) or 10 like Θ(n¹⁰) or a thousand Θ(n¹⁰⁰⁰) but k is not a function of n. It can't be an exponential or it's going to be bounded by some polynomial. It could be a nasty polynomial, but let's just imagine that it's bounded by a polynomial.
We had a planar graph. >>About the planar graphs. >>Yup. And then--so you said draw yourself a planar graph but we know the relation n-m+r=2. I did actually draw a graph as well, in fact two.
It's a usual thing to note that there's a relationship between the class NP and the cluster problems that are solvable in exponential time. Any problems that's in NP is also going to be solvable in exponential time. So the set of exponential time solvable problems includes NP.
I want to make little townhouse shapes with toothpicks. So this would be my first townhouse. I've used 3 toothpicks so far-- 4, 5, and 6.
Basically, I calculated the chain first and then I calculated all the other ones where I couldn't count between the 0 in the first element because I'd already done that and so it's just one list and write down a whole lot mixed--that one was straight. So it was less than 2n for the combination ??? so it has to be Θ(n). >>Okay. >>And then n-1 links to get the chain. >>Yup. And then n-2 links to get all the rest.
My travels to Afghanistan began many, many years ago on the eastern border of my country, my homeland, Poland. I was walking through the forests of my grandmother's tales. A land where every field hides a grave, where millions of people have been deported or killed in the 20th century.
So we just discussed the number of distribution channels available to a startup and we talked about picking one but what's really interesting is the solution complexity that each channel can handle. That is system integrators are designed to handle complex systems. And so therefore on the x-axis, we see increasing complexity of what each channel can actually have.
Now speaking precisely. A heap isn't actually any particular data structure with some particular running time. It's actually kind of an abstract data type.
Regina rode her bike 2 and 1/4 miles from her house to school and then 1 and 5/8 miles to her friend's house. How many miles did Regina ride in total? So she first rode 2 and 1/4 miles, and then she rode 1 and 5/8 miles. then she rode 1 and 5/8 miles
8 goes into 9 one time with 1 left over, so it's 1 and 1/8. So this is the same thing as 3 plus 1 and 1/8. So now we can add the whole number parts.
4 and 1/8. I just wanted to give you that special circumstance when your fraction part ends up improper.
A recipe for banana oat muffins calls for 3/4 of a cup of old-fashioned oats. You are making 1/2 of the recipe. How much oats should you use?
So you just multiply 1/2 times 3/4, and this is equal to-- you multiply the numerators.
1 times 3 is 3.
2 times 4 is 8. And we're done! You need 3/8 of a cup of old-fashioned oats.
So you would want this many oats. Now, let's think about what that is relative to a whole cup. Well, one way we can do it is to turn each of these four buckets, or these four pieces, or these four sections of a cup into eight sections of a cup.
So we're essentially turning each piece, each fourth, into two pieces. So let's divide each of them into two. So this is the first piece.
One, two, three, four, five, six, seven, eight, because we turned each of the four, we split them again into eight, so we have 8 as the denominator, and we took half of the 3/4, right? Remember, 3/4 was in orange. Let me make this very clear because this drawing can get confusing.
I'm not going to do a presentation on a type of integral. I guess if you have this in your tool kit-- and actually you have it beyond the exam on this type of integral, and you actually keep it and you retain it, then you, I think, will become an integration jock. But anyway, let me show you what I'm talking about.
So let's say I had two functions, let's say f of x times g of x, and I wanted to take the derivative of this. f of x times g of x. Well the chain rule just told us that this is just the same thing as, let's say, the derivative of the first function f prime of x times the second function g of x plus now the first function f of x times the derivative of the second function. And I'll show you where I'm going with this in a second.
So what did I just do? It looks like I just-- well, I am just essentially playing with the product rule from differentiation. That's all I did.
So if you encounter this when you're doing integrals, kind of the last tool kit-- and this is pretty sophisticated-- is to do integration by parts. And so how can we use this for integration by parts? Well, integration by parts tells us that if we have an integral where we have a function and then the derivative of another function, then we could use this formula to hopefully simplify it.
So that's x. And let's say g of x is cosine of x, right? I'm sorry, g prime of x is cosine of x.
And I think you would agree that we've now simplified this a good bit, because this is just the integral of sine of x, right? So this is just equal to x sine of x-- this is just this first term right here-- minus-- and what's the integral of sine of x? Well, the derivative of-- well, let me make it even simpler.
Miranda's Maid Service charges $280 to clean 8 offices. What is the company's price for cleaning a single office? So they charge $280 to clean 8 offices.
Chapter I. Down the Rabbit-Hole Alice was beginning to get very tired of sitting by her sister on the bank, and of having nothing to do: once or twice she had peeped into the book her sister was reading, but it had no pictures or conversations in it, 'and what is the use of a book,' thought Alice 'without pictures or conversation?'
So she was considering in her own mind (as well as she could, for the hot day made her feel very sleepy and stupid), whether the pleasure of making a daisy-chain would be worth the trouble of getting up and picking the daisies, when suddenly a White Rabbit with pink eyes ran close by her. There was nothing so VERY remarkable in that; nor did Alice think it so VERY much out of the way to hear the Rabbit say to itself, 'Oh dear! Oh dear!
The Antipathies, I think--' (she was rather glad there WAS no one listening, this time, as it didn't sound at all the right word) '--but I shall have to ask them what the name of the country is, you know. Please, Ma'am, is this New Zealand or Australia?' (and she tried to curtsey as she spoke-- fancy CURTSEYlNG as you're falling through the air!
'Dinah'll miss me very much to-night, I should think!' (Dinah was the cat.) 'I hope they'll remember her saucer of milk at tea-time. Dinah my dear!
'Do bats eat cats?' for, you see, as she couldn't answer either question, it didn't much matter which way she put it. She felt that she was dozing off, and had just begun to dream that she was walking hand in hand with Dinah, and saying to her very earnestly, 'Now, Dinah, tell me the truth: did you ever eat a bat?' when suddenly, thump! thump! down she came upon a heap of sticks and dry leaves, and the fall was over. Alice was not a bit hurt, and she jumped up on to her feet in a moment: she looked up, but it was all dark overhead; before her was another long passage, and the White
How she longed to get out of that dark hall, and wander about among those beds of bright flowers and those cool fountains, but she could not even get her head through the doorway; 'and even if my head would go through,' thought poor Alice, 'it would be of very little use without my shoulders. Oh, how I wish I could shut up like a telescope! I think I could, if I only know how to begin.'
'No, I'll look first,' she said, 'and see whether it's marked "poison" or not'; for she had read several nice little histories about children who had got burnt, and eaten up by wild beasts and other unpleasant things, all because they WOULD not remember the simple rules their friends had taught them: such as, that a red-hot poker will burn you if you hold it too long; and that if you cut your finger VERY deeply with a knife, it usually bleeds; and she had never forgotten that, if you drink much from a bottle marked 'poison,' it is almost certain to disagree with you, sooner or later. However, this bottle was NOT marked 'poison,' so Alice ventured to taste it, and finding it very nice, (it had, in fact, a sort of mixed flavour of cherry-tart, custard, pine-apple, roast turkey, toffee, and hot buttered toast,) she very soon finished it off.
'Curiouser and curiouser!' cried Alice (she was so much surprised, that for the moment she quite forgot how to speak good English); 'now I'm opening out like the largest telescope that ever was!
Good-bye, feet!' (for when she looked down at her feet, they seemed to be almost out of sight, they were getting so far off). 'Oh, my poor little feet, I wonder who will put on your shoes and stockings for you now, dears? I'm sure I shan't be able!
ALlCE'S RlGHT FOOT, ESQ. HEARTHRUG, NEAR THE FENDER, (WlTH ALlCE'S LOVE).
'How cheerfully he seems to grin, How neatly spread his claws, And welcome little fishes in With gently smiling jaws!'
'I'm sure those are not the right words,' said poor Alice, and her eyes filled with tears again as she went on, 'I must be Mabel after all, and I shall have to go and live in that poky little house, and have next to no toys to play with, and oh! ever so many lessons to learn! No, I've made up my mind about it; if I'm Mabel, I'll stay down here!
'A mouse--of a mouse--to a mouse--a mouse-- O mouse!') The Mouse looked at her rather inquisitively, and seemed to her to wink with one of its little eyes, but it said nothing. 'Perhaps it doesn't understand English,' thought Alice; 'I daresay it's a French mouse, come over with William the Conqueror.'
'I'm afraid I've offended it again!' For the Mouse was swimming away from her as hard as it could go, and making quite a commotion in the pool as it went. So she called softly after it, 'Mouse dear!
'Sit down, all of you, and listen to me! I'LL soon make you dry enough!' They all sat down at once, in a large ring, with the Mouse in the middle.
Northumbria, declared for him: and even Stigand, the patriotic archbishop of Canterbury, found it advisable--"'
'Found WHAT?' said the Duck. 'Found IT,' the Mouse replied rather crossly: 'of course you know what "it" means.'
The question is, what did the archbishop find?'
(And, as you might like to try the thing yourself, some winter day, I will tell you how the Dodo managed it.) First it marked out a race-course, in a sort of circle, ('the exact shape doesn't matter,' it said,) and then all the party were placed along the course, here and there. There was no 'One, two, three, and away,' but they began running when they liked, and
'Fury said to a mouse, That he met in the house,
"Let us both go to law: I will prosecute YOU.--Come, I'll take no denial; We must have a trial:
"I'll be judge, I'll be jury," Said cunning old Fury: "I'll try the whole cause, and condemn you to death."'
'You are not attending!' said the Mouse to Alice severely. 'What are you thinking of?' 'I beg your pardon,' said Alice very humbly: 'you had got to the fifth bend, I think?'
'I had NOT!' cried the Mouse, sharply and very angrily. 'A knot!' said Alice, always ready to make herself useful, and looking anxiously about her. 'Oh, do let me help to undo it!'
As she said this, she came upon a neat little house, on the door of which was a bright brass plate with the name 'W. RABBlT' engraved upon it. She went in without knocking, and hurried upstairs, in great fear lest she should meet the real Mary Ann, and be turned out of the house before she had found the fan and gloves.
"Coming in a minute, nurse! But I've got to see that the mouse doesn't get out." Only I don't think,' Alice went on, 'that they'd let Dinah stop in the house if it began ordering people about like that!'
'But then,' thought Alice, 'shall I NEVER get any older than I am now? That'll be a comfort, one way--never to be an old woman--but then--always to have lessons to learn!
'Digging for apples, indeed!' said the Rabbit angrily. 'Here! Come and help me out of THlS!'
'Now tell me, Pat, what's that in the window?' 'Sure, it's an arm, yer honour!' (He pronounced it 'arrum.')
'An arm, you goose! Who ever saw one that size? Why, it fills the whole window!'
'Sure, it does, yer honour: but it's an arm for all that.' 'Well, it's got no business there, at any rate: go and take it away!' There was a long silence after this, and Alice could only hear whispers now and then; such as, 'Sure, I don't like it, yer honour, at all, at all!'
'Do as I tell you, you coward!' and at last she spread out her hand again, and made another snatch in the air. This time there were TWO little shrieks, and more sounds of broken glass. 'What a number of cucumber-frames there must be!' thought Alice.
little animal (she couldn't guess of what sort it was) scratching and scrambling about in the chimney close above her: then, saying to herself 'This is Bill,' she gave one sharp kick, and waited to see what would happen next. The first thing she heard was a general chorus of 'There goes Bill!' then the Rabbit's voice along--'Catch him, you by the hedge!' then silence, and then another confusion of voices--'Hold up his head--
'So you did, old fellow!' said the others. 'We must burn the house down!' said the Rabbit's voice; and Alice called out as If they had any sense, they'd take the roof off.'
'What do you mean by that?' said the Caterpillar sternly. 'Explain yourself!' 'I can't explain MYSELF, I'm afraid, sir' said Alice, 'because I'm not myself, you see.'
'I don't see,' said the Caterpillar. 'I'm afraid I can't put it more clearly,' Alice replied very politely, 'for I can't understand it myself to begin with; and being so many different sizes in a day is very confusing.' 'It isn't,' said the Caterpillar.
'Not a bit,' said the Caterpillar. 'Well, perhaps your feelings may be different,' said Alice; 'all I know is, it would feel very queer to ME.'
'You!' said the Caterpillar contemptuously. 'Who are YOU?' Which brought them back again to the beginning of the conversation.
'Can't remember WHAT things?' said the Caterpillar. 'Well, I've tried to say "HOW DOTH THE LlTTLE BUSY BEE," but it all came different!' Alice replied in a very melancholy voice.
'In my youth,' Father William replied to his son, I feared it might injure the brain; But, now that I'm perfectly sure I have none,
'You are old,' said the youth, 'as I mentioned before, And have grown most uncommonly fat; Yet you turned a back-somersault in at the door--
'In my youth,' said the sage, as he shook his grey locks,
'I kept all my limbs very supple By the use of this ointment-- one shilling the box-- Allow me to sell you a couple?'
'You are old,' said the youth, 'and your jaws are too weak For anything tougher than suet; Yet you finished the goose, with the bones and the beak--
'In my youth,' said his father, 'I took to the law, And argued each case with my wife; And the muscular strength, which it gave to my jaw,
'You are old,' said the youth, 'one would hardly suppose That your eye was as steady as ever; Yet you balanced an eel on the end of your nose--
'I have answered three questions, and that is enough,' Said his father; 'don't give yourself airs! Do you think I can listen all day to such stuff?
'That is not said right,' said the Caterpillar. 'Not QUlTE right, I'm afraid,' said Alice, timidly; 'some of the words have got altered.'
'It is wrong from beginning to end,' said the Caterpillar decidedly, and there was silence for some minutes. The Caterpillar was the first to speak. 'What size do you want to be?' it asked.
'Oh, I'm not particular as to size,' Alice hastily replied; 'only one doesn't like changing so often, you know.' 'I DON'T know,' said the Caterpillar. Alice said nothing: she had never been so much contradicted in her life before, and she felt that she was losing her temper.
'I'm very sorry you've been annoyed,' said Alice, who was beginning to see its meaning. 'And just as I'd taken the highest tree in the wood,' continued the Pigeon, raising its voice to a shriek, 'and just as I was thinking I should be free of them at last, they must needs come wriggling down from the sky! Ugh, Serpent!'
'I--I'm a little girl,' said Alice, rather doubtfully, as she remembered the number of changes she had gone through that day. 'A likely story indeed!' said the Pigeon in a tone of the deepest contempt. 'I've seen a good many little girls in my time, but never ONE with such a neck as that!
'I don't believe it,' said the Pigeon; 'but if they do, why then they're a kind of serpent, that's all I can say.' This was such a new idea to Alice, that she was quite silent for a minute or two, which gave the Pigeon the opportunity of adding, 'You're looking for eggs, I know THAT well enough; and what does it matter to me whether you're a little girl or a serpent?'
'It matters a good deal to ME,' said Alice hastily; 'but I'm not looking for eggs, as it happens; and if I was, I shouldn't want YOURS: I don't like them raw.' 'Well, be off, then!' said the Pigeon in a sulky tone, as it settled down again into its nest.
'For the Duchess. An invitation from the Queen to play croquet.' The Frog-Footman repeated, in the same solemn tone, only changing the order of the words a little, 'From the Queen.
'There might be some sense in your knocking,' the Footman went on without attending to her, 'if we had the door between us. For instance, if you were INSlDE, you might knock, and I could let you out, you know.' He was looking up into the sky all the time he was speaking, and this Alice thought decidedly uncivil.
'But what am I to do?' said Alice. 'Anything you like,' said the Footman, and began whistling. 'Oh, there's no use in talking to him,' said Alice desperately: 'he's perfectly idiotic!'
'It's a Cheshire cat,' said the Duchess, 'and that's why. Pig!' She said the last word with such sudden violence that Alice quite jumped; but she saw in another moment that it was addressed to the baby, and not to her, so she took courage, and went on again:--
'I didn't know that Cheshire cats always grinned; in fact, I didn't know that cats
'They all can,' said the Duchess; 'and most of 'em do.'
'I don't know of any that do,' Alice said very politely, feeling quite pleased to have got into a conversation. 'You don't know much,' said the Duchess;
'and that's a fact.' Alice did not at all like the tone of this remark, and thought it would be as well to introduce some other subject of conversation. While she was trying to fix on one, the cook took the cauldron of soup off the fire, and at once set to work throwing everything within her reach at the Duchess and the baby--the fire-irons came first; then followed a shower of saucepans, plates, and dishes.
'Which would NOT be an advantage,' said Alice, who felt very glad to get an opportunity of showing off a little of her knowledge. 'Just think of what work it would make with the day and night! You see the earth takes twenty-four hours to turn round on its axis--'
He only does it to annoy, Because he knows it teases.'
(In which the cook and the baby joined): 'Wow! wow! wow!' While the Duchess sang the second verse of the song, she kept tossing the baby violently up and down, and the poor little thing howled so, that Alice could hardly hear the words:--
'In THAT direction,' the Cat said, waving its right paw round, 'lives a Hatter: and in THAT direction,' waving the other paw, 'lives a March Hare. Visit either you like: they're both mad.' 'But I don't want to go among mad people,' Alice remarked.
'I should like it very much,' said Alice,
'but I haven't been invited yet.' 'You'll see me there,' said the Cat, and vanished. Alice was not much surprised at this, she was getting so used to queer things happening.
'It turned into a pig,' Alice quietly said, just as if it had come back in a natural way. 'I thought it would,' said the Cat, and vanished again. Alice waited a little, half expecting to see it again, but it did not appear, and after a minute or two she walked on in the direction in which the March Hare was said to live.
'I didn't know it was YOUR table,' said Alice; 'it's laid for a great many more than three.' 'Your hair wants cutting,' said the Hatter. He had been looking at Alice for some time with great curiosity, and this was his first speech.
The Hatter opened his eyes very wide on hearing this; but all he SAlD was, 'Why is a raven like a writing-desk?' 'Come, we shall have some fun now!' thought Alice.
'You might just as well say,' added the Dormouse, who seemed to be talking in his sleep, 'that "I breathe when I sleep" is the same thing as "I sleep when I breathe"!'
'It IS the same thing with you,' said the Hatter, and here the conversation dropped, and the party sat silent for a minute, while Alice thought over all she could remember about ravens and writing-desks, which wasn't much. The Hatter was the first to break the silence. 'What day of the month is it?' he said, turning to Alice: he had taken his watch out of his pocket, and was looking at it uneasily, shaking it every now and then, and holding it to his ear.
'Of course not,' Alice replied very readily: 'but that's because it stays the same year for such a long time together.' 'Which is just the case with MlNE,' said the Hatter. Alice felt dreadfully puzzled.
'If you knew Time as well as I do,' said the Hatter, 'you wouldn't talk about wasting IT. It's HlM.'
'I don't know what you mean,' said Alice. 'Of course you don't!' the Hatter said, tossing his head contemptuously. 'I dare say you never even spoke to Time!'
'That would be grand, certainly,' said Alice thoughtfully: 'but then--I shouldn't be hungry for it, you know.'
'Not at first, perhaps,' said the Hatter: 'but you could keep it to half-past one as long as you liked.' 'Is that the way YOU manage?'
"Twinkle, twinkle, little bat! How I wonder what you're at!"
You know the song, perhaps?' 'I've heard something like it,' said Alice. 'It goes on, you know,' the Hatter continued, 'in this way:--
"Up above the world you fly, Like a tea-tray in the sky. Twinkle, twinkle--"' Here the Dormouse shook itself, and began singing in its sleep 'Twinkle, twinkle, twinkle, twinkle--' and went on so long that they had to pinch it to make it stop.
'How dreadfully savage!' exclaimed Alice. 'And ever since that,' the Hatter went on in a mournful tone, 'he won't do a thing I ask! It's always six o'clock now.'
'But what happens when you come to the beginning again?' Alice ventured to ask. 'Suppose we change the subject,' the March Hare interrupted, yawning.
'I'm afraid I don't know one,' said Alice, rather alarmed at the proposal. 'Then the Dormouse shall!' they both cried. 'Wake up, Dormouse!'
'or you'll be asleep again before it's done.' 'Once upon a time there were three little sisters,' the Dormouse began in a great hurry; 'and their names were Elsie, Lacie, and Tillie; and they lived at the bottom of a well--' 'What did they live on?' said Alice, who always took a great interest in questions of eating and drinking.
'Take some more tea,' the March Hare said to Alice, very earnestly. 'I've had nothing yet,' Alice replied in an offended tone, 'so I can't take more.' 'You mean you can't take LESS,' said the Hatter: 'it's very easy to take MORE than nothing.'
'Nobody asked YOUR opinion,' said Alice. 'Who's making personal remarks now?' the Hatter asked triumphantly. Alice did not quite know what to say to this: so she helped herself to some tea and bread-and-butter, and then turned to the Dormouse, and repeated her question.
Alice said very humbly; 'I won't interrupt again.
'But they were IN the well,' Alice said to the Dormouse, not choosing to notice this last remark. 'Of course they were', said the Dormouse;
'--well in.' This answer so confused poor Alice, that she let the Dormouse go on for some time without interrupting it. 'They were learning to draw,' the Dormouse went on, yawning and rubbing its eyes, for it was getting very sleepy; 'and they drew all manner of things--everything that begins with an M--'
'Why with an M?' said Alice. 'Why not?' said the March Hare. Alice was silent.
'Then you shouldn't talk,' said the Hatter. This piece of rudeness was more than Alice could bear: she got up in great disgust, and walked off; the Dormouse fell asleep instantly, and neither of the others took the least notice of her going, though she looked back once or twice, half hoping that they would call after her: the last time she saw them, they were trying to put the Dormouse into the teapot.
HEARTS. Alice was rather doubtful whether she ought not to lie down on her face like the three gardeners, but she could not remember ever having heard of such a rule at processions; 'and besides, what would be the use of a procession,' thought she, 'if people had all to lie down upon their faces, so that they couldn't see it?'
'And who are THESE?' said the Queen, pointing to the three gardeners who were lying round the rosetree; for, you see, as they were lying on their faces, and the pattern on their backs was the same as the rest of the pack, she could not tell whether they were gardeners, or soldiers, or courtiers, or three of her own children. 'How should I know?' said Alice, surprised at her own courage.
'Nonsense!' said Alice, very loudly and decidedly, and the Queen was silent. The King laid his hand upon her arm, and timidly said 'Consider, my dear: she is only a child!' The Queen turned angrily away from him, and said to the Knave 'Turn them over!'
'It's--it's a very fine day!' said a timid voice at her side. She was walking by the White Rabbit, who was peeping anxiously into her face. 'Very,' said Alice: '--where's the Duchess?'
'What for?' said Alice. 'Did you say "What a pity!" ?' the Rabbit asked. 'No, I didn't,' said Alice:
Alice began to feel very uneasy: to be sure, she had not as yet had any dispute with the Queen, but she knew that it might happen any minute, 'and then,' thought she,
'what would become of me? They're dreadfully fond of beheading people here; the great wonder is, that there's any one left alive!' She was looking about for some way of escape, and wondering whether she could get away without being seen, when she noticed a curious appearance in the air: it puzzled her very much at first, but, after watching it a minute or two, she made it out to be a grin, and she said to herself 'It's the
'I'd rather not,' the Cat remarked. 'Don't be impertinent,' said the King, 'and don't look at me like that!' He got behind Alice as he spoke.
(It was this last remark that had made the whole party look so grave and anxious.) Alice could think of nothing else to say but 'It belongs to the Duchess: you'd better ask HER about it.'
'She's in prison,' the Queen said to the executioner: 'fetch her here.' And the executioner went off like an arrow. The Cat's head began fading away the moment he was gone, and, by the time he had come back with the Duchess, it had entirely disappeared; so the King and the executioner ran wildly up and down looking for it, while the rest of the party went back to the game. >
'You can't think how glad I am to see you again, you dear old thing!' said the Duchess, as she tucked her arm affectionately into Alice's, and they walked off together. Alice was very glad to find her in such a pleasant temper, and thought to herself that perhaps it was only the pepper that had made her so savage when they met in the kitchen.
'Perhaps it hasn't one,' Alice ventured to remark.
'Tut, tut, child!' said the Duchess. 'Everything's got a moral, if only you can find it.' And she squeezed herself up closer to Alice's side as she spoke.
'Somebody said,' Alice whispered, 'that it's done by everybody minding their own business!' 'Ah, well! It means much the same thing,' said the Duchess, digging her sharp little chin into
'How fond she is of finding morals in things!' Alice thought to herself. 'I dare say you're wondering why I don't put my arm round your waist,' the Duchess said after a pause: 'the reason is, that I'm doubtful about the temper of your flamingo.
'Only mustard isn't a bird,' Alice remarked. 'Right, as usual,' said the Duchess: 'what a clear way you have of putting things!' 'It's a mineral, I THlNK,' said Alice.
'Oh, I know!' exclaimed Alice, who had not attended to this last remark, 'it's a vegetable. It doesn't look like one, but it is.'
'I quite agree with you,' said the Duchess; 'and the moral of that is--"Be what you would seem to be"--or if you'd like it put more simply--"Never imagine yourself not to be otherwise than what it might appear to others that what you were or might have been was not otherwise than what you had been would have appeared to them to be otherwise."'
'I think I should understand that better,' Alice said very politely, 'if I had it written down: but I can't quite follow it as you say it.' 'That's nothing to what I could say if I chose,' the Duchess replied, in a pleased tone. 'Pray don't trouble yourself to say it any
'either you or your head must be off, and that in about half no time! Take your choice!' The Duchess took her choice, and was gone in a moment.
'No,' said Alice. 'I don't even know what a Mock Turtle is.' 'It's the thing Mock Turtle Soup is made from,' said the Queen.
(IF you don't know what a Gryphon is, look at the picture.) 'Up, lazy thing!' said the Queen, 'and take this young lady to see the Mock Turtle, and to hear his history. I must go back and see after some executions I have ordered'; and she walked off, leaving Alice alone with the Gryphon.
The Gryphon sat up and rubbed its eyes: then it watched the Queen till she was out of sight: then it chuckled. 'What fun!' said the Gryphon, half to itself, half to Alice. 'What IS the fun?' said Alice.
'Everybody says "come on!" here,' thought Alice, as she went slowly after it: 'I never was so ordered about in all my life, never!' They had not gone far before they saw the Mock Turtle in the distance, sitting sad and lonely on a little ledge of rock, and, as they came nearer, Alice could hear him sighing as if his heart would break.
'I'll tell it her,' said the Mock Turtle in a deep, hollow tone: 'sit down, both of you, and don't speak a word till I've finished.' So they sat down, and nobody spoke for some minutes. Alice thought to herself, 'I don't see how he can EVEN finish, if he doesn't begin.'
These words were followed by a very long silence, broken only by an occasional exclamation of 'Hjckrrh!' from the Gryphon, and the constant heavy sobbing of the Mock Turtle. Alice was very nearly getting up and saying, 'Thank you, sir, for your interesting story,' but she could not help thinking there MUST be more to come, so she sat still and said nothing.
'Why did you call him Tortoise, if he wasn't one?' Alice asked. 'We called him Tortoise because he taught us,' said the Mock Turtle angrily: 'really you are very dull!'
'You ought to be ashamed of yourself for asking such a simple question,' added the
Gryphon; and then they both sat silent and looked at poor Alice, who felt ready to sink into the earth. At last the Gryphon said to the Mock Turtle, 'Drive on, old fellow! Don't be all day about it!' and he went on in these words:
'I never said I didn't!' interrupted Alice. 'You did,' said the Mock Turtle. 'Hold your tongue!' added the Gryphon, before Alice could speak again.
'You couldn't have wanted it much,' said Alice; 'living at the bottom of the sea.' 'I couldn't afford to learn it.' said the Mock Turtle with a sigh. 'I only took the regular course.'
'I never heard of "Uglification,"' Alice ventured to say.
The Gryphon lifted up both its paws in surprise.
Never heard of uglifying!' it exclaimed. 'You know what to beautify is, I suppose?' 'Yes,' said Alice doubtfully: 'it means-- to--make--anything--prettier.'
'Well, then,' the Gryphon went on, 'if you don't know what to uglify is, you ARE a simpleton.' Alice did not feel encouraged to ask any more questions about it, so she turned to the Mock Turtle, and said 'What else had you to learn?' 'Well, there was Mystery,' the Mock Turtle replied, counting off the subjects on his flappers, '--Mystery, ancient and modern, with Seaography: then Drawling--the
Coils.' 'What was THAT like?' said Alice. 'Well, I can't show it you myself,' the Mock Turtle said:
'That's the reason they're called lessons,' the Gryphon remarked: 'because they lessen from day to day.' This was quite a new idea to Alice, and she thought it over a little before she made her next remark. 'Then the eleventh day must have been a holiday?'
'Seals, turtles, salmon, and so on; then, when you've cleared all the jelly-fish out of the way--' 'THAT generally takes some time,' interrupted the Gryphon. '--you advance twice--' 'Each with a lobster as a partner!' cried the Gryphon.
'Of course,' the Mock Turtle said: 'advance twice, set to partners--'
'--change lobsters, and retire in same order,' continued the Gryphon. 'Then, you know,' the Mock Turtle went on, 'you throw the--'
'The lobsters!' shouted the Gryphon, with a bound into the air. '--as far out to sea as you can--' 'Swim after them!' screamed the Gryphon.
'Turn a somersault in the sea!' cried the Mock Turtle, capering wildly about. 'Change lobsters again!' yelled the Gryphon at the top of its voice. 'Back to land again, and that's all the first figure,' said the Mock Turtle, suddenly dropping his voice; and the two creatures, who had been jumping about like mad things all this time, sat down again very sadly and quietly, and looked at Alice.
'Come, let's try the first figure!' said the Mock Turtle to the Gryphon. 'We can do without lobsters, you know. Which shall sing?'
'Oh, YOU sing,' said the Gryphon. 'I've forgotten the words.' So they began solemnly dancing round and round Alice, every now and then treading on her toes when they passed too close, and waving their forepaws to mark the time, while the Mock Turtle sang this, very slowly and sadly:--
'"Will you walk a little faster?" said a whiting to a snail.
"There's a porpoise close behind us, and he's treading on my tail. See how eagerly the lobsters and the turtles all advance! They are waiting on the shingle--will you come and join the dance?
'Thank you, it's a very interesting dance to watch,' said Alice, feeling very glad that it was over at last: 'and I do so like that curious song about the whiting!' 'Oh, as to the whiting,' said the Mock Turtle, 'they--you've seen them, of course?'
'Yes,' said Alice, 'I've often seen them at dinn--' she checked herself hastily. 'I don't know where Dinn may be,' said the Mock Turtle, 'but if you've seen them so often, of course you know what they're like.'
'I believe so,' Alice replied thoughtfully. 'They have their tails in their mouths--and they're all over crumbs.'
'You're wrong about the crumbs,' said the Mock Turtle: 'crumbs would all wash off in the sea. But they HAVE their tails in their mouths; and the reason is--' here the Mock Turtle yawned and shut his eyes. --'Tell her about the reason and all that,' he said to the Gryphon.
'Thank you,' said Alice, 'it's very interesting. I never knew so much about a whiting before.'
'I can tell you more than that, if you like,' said the Gryphon. 'Do you know why it's called a whiting?' 'I never thought about it,' said Alice.
Gryphon went on in a deep voice, 'are done with a whiting. Now you know.' 'And what are they made of?'
'If I'd been the whiting,' said Alice, whose thoughts were still running on the song, 'I'd have said to the porpoise, "Keep back, please: we don't want YOU with us!"' 'They were obliged to have him with them,' the Mock Turtle said: 'no wise fish would go anywhere without a porpoise.' 'Wouldn't it really?' said Alice in a tone of great surprise.
'Don't you mean "purpose"?' said Alice. 'I mean what I say,' the Mock Turtle replied in an offended tone. And the Gryphon added 'Come, let's hear some of YOUR adventures.'
"You have baked me too brown, I must sugar my hair." As a duck with its eyelids, so he with his nose Trims his belt and his buttons, and turns out his toes.'
'That's different from what I used to say when I was a child,' said the Gryphon. 'Well, I never heard it before,' said the Mock Turtle; 'but it sounds uncommon nonsense.' Alice said nothing; she had sat down with her face in her hands, wondering if anything would EVER happen in a natural way again.
'It's the first position in dancing.' Alice said; but was dreadfully puzzled by the whole thing, and longed to change the subject. 'Go on with the next verse,' the Gryphon repeated impatiently: 'it begins "I passed by his garden."'
'I passed by his garden, and marked, with one eye, How the Owl and the Panther were sharing a pie--' [later editions continued as follows The Panther took pie-crust, and gravy, and meat, While the Owl had the dish as its share of the treat.
It's by far the most confusing thing I ever heard!'
'Yes, I think you'd better leave off,' said the Gryphon: and Alice was only too glad to do so. 'Shall we try another figure of the Lobster Quadrille?' the Gryphon went on.
'Oh, a song, please, if the Mock Turtle would be so kind,' Alice replied, so eagerly that the Gryphon said, in a rather offended tone, 'Hm! No accounting for tastes! Sing her "Turtle Soup," will you, old fellow?'
'Beautiful Soup, so rich and green, Waiting in a hot tureen! Who for such dainties would not stoop? Soup of the evening, beautiful Soup!
'Soo--oop of the e--e--evening, Beautiful, beautiful Soup!' > Chapter Xl. Who Stole the Tarts?
'Stupid things!' Alice began in a loud, indignant voice, but she stopped hastily, for the White Rabbit cried out, 'Silence in the court!' and the King put on his spectacles and looked anxiously round, to make out who was talking. Alice could see, as well as if she were looking over their shoulders, that all the jurors were writing down 'stupid things!' on their slates, and she could even make out that one of them didn't know how to spell 'stupid,' and that he had to ask his neighbour to tell him.
'The Queen of Hearts, she made some tarts, All on a summer day: The Knave of Hearts, he stole those tarts, And took them quite away!'
'Consider your verdict,' the King said to the jury. 'Not yet, not yet!' the Rabbit hastily interrupted.
'There's a great deal to come before that!' 'Call the first witness,' said the King; and the White Rabbit blew three blasts on the trumpet, and called out, 'First witness!' The first witness was the Hatter.
'You ought to have finished,' said the King. 'When did you begin?' 'Fourteenth of March, I think it was,' he said.
'It began with the tea,' the Hatter replied.
'I'm a poor man,' the Hatter went on, 'and most things twinkled after that--only the
March Hare said--' 'I didn't!' the March Hare interrupted in a great hurry. 'You did!' said the Hatter. 'I deny it!' said the March Hare.
'But what did the Dormouse say?' one of the jury asked. 'That I can't remember,' said the Hatter. 'You MUST remember,' remarked the King, 'or I'll have you executed.'
(As that is rather a hard word, I will just explain to you how it was done. They had a large canvas bag, which tied up at the mouth with strings: into this they slipped the guinea-pig, head first, and then sat upon it.)
'I'm glad I've seen that done,' thought Alice. 'I've so often read in the newspapers, at the end of trials, "There was some attempts at applause, which was immediately suppressed by the officers of the court," and I never understood what it meant till now.'
'If that's all you know about it, you may stand down,' continued the King. 'I can't go no lower,' said the Hatter: 'I'm on the floor, as it is.'
'Well, if I must, I must,' the King said, with a melancholy air, and, after folding his arms and frowning at the cook till his eyes were nearly out of sight, he said in a deep voice, 'What are tarts made of?' 'Pepper, mostly,' said the cook. 'Treacle,' said a sleepy voice behind her.
'Oh, I BEG your pardon!' she exclaimed in a tone of great dismay, and began picking them up again as quickly as she could, for the accident of the goldfish kept running in her head, and she had a vague sort of idea that they must be collected at once and put back into the jury-box, or they would die. 'The trial cannot proceed,' said the King in a very grave voice, 'until all the jurymen are back in their proper places-- ALL,' he repeated with great emphasis, looking hard at Alice as he said do.
'It's the oldest rule in the book,' said the King. 'Then it ought to be Number One,' said Alice. The King turned pale, and shut his note- book hastily.
'It must have been that,' said the King, 'unless it was written to nobody, which isn't usual, you know.' 'Who is it directed to?' said one of the jurymen. 'It isn't directed at all,' said the White Rabbit; 'in fact, there's nothing written on the OUTSlDE.'
(The jury all looked puzzled.) 'He must have imitated somebody else's hand,' said the King. (The jury all brightened up again.) 'Please your Majesty,' said the Knave, 'I didn't write it, and they can't prove I did: there's no name signed at the end.' 'If you didn't sign it,' said the King, 'that only makes the matter worse.
'They told me you had been to her, And mentioned me to him: She gave me a good character, But said I could not swim. He sent them word I had not gone (We know it to be true):
'That's the most important piece of evidence we've heard yet,' said the King, rubbing his hands; 'so now let the jury--'
'If any one of them can explain it,' said Alice, (she had grown so large in the last few minutes that she wasn't a bit afraid of interrupting him,) 'I'll give him sixpence.
I don't believe there's an atom of meaning in it.' The jury all wrote down on their slates, 'SHE doesn't believe there's an atom of meaning in it,' but none of them attempted to explain the paper. 'If there's no meaning in it,' said the King, 'that saves a world of trouble, you know, as we needn't try to find any.
(Which he certainly did NOT, being made entirely of cardboard.)
'All right, so far,' said the King, and he went on muttering over the verses to himself: '"WE KNOW IT TO BE TRUE--" that's the jury, of course--"I GAVE HER ONE, THEY GAVE HlM TWO--" why, that must be what he did with the tarts, you know--' 'But, it goes on "THEY ALL RETURNED FROM HlM TO YOU,"' said Alice.
(The unfortunate little Bill had left off writing on his slate with one finger, as he found it made no mark; but he now hastily began again, using the ink, that was trickling down his face, as long as it lasted.) 'Then the words don't FlT you,' said the King, looking round the court with a smile. There was a dead silence.
'You're nothing but a pack of cards!' At this the whole pack rose up into the air, and came flying down upon her: she gave a little scream, half of fright and half of anger, and tried to beat them off, and found herself lying on the bank, with her head in the lap of her sister, who was gently brushing away some dead leaves that had fluttered down from the trees upon her face. 'Wake up, Alice dear!' said her sister; 'Why, what a long sleep you've had!'
So she sat on, with closed eyes, and half believed herself in Wonderland, though she knew she had but to open them again, and all would change to dull reality--the grass would be only rustling in the wind, and the pool rippling to the waving of the reeds-- the rattling teacups would change to tinkling sheep-bells, and the Queen's shrill cries to the voice of the shepherd boy--and the sneeze of the baby, the shriek of the Gryphon, and all the other queer noises, would change (she knew) to the confused clamour of the busy farm-yard-- while the lowing of the cattle in the distance would take the place of the Mock Turtle's heavy sobs. Lastly, she pictured to herself how this same little sister of hers would, in the after-time, be herself a grown woman; and how she would keep, through all her riper years, the simple and loving heart of her childhood: and how she would gather about her other little children, and make THElR eyes bright and eager with many a strange tale, perhaps even with the dream of Wonderland of long ago: and how she would feel with all their simple sorrows, and find a pleasure in all their simple joys, remembering her own child-life, and the happy summer days.
THE END >
Let's say this past year I started a restaurant. Now I wanna think about what type of profit I've been making at that restaurant. We're gonna think about it in two different ways.
Welcome to the presentation on graphing lines. Let's get started. So let's say I had the equation-- let me make sure that this line doesn't show up too thick.
And let's just throw out some random numbers for x. If x was let's say, negative 1, then y would be 2 times negative 1, which is negative 2.
Plus 1, which would be negative 1. If x was 0 that's easy. It'd be 2 times 0, which is 0.
Okay, let me draw some coordinate points. So let's say that's 1, that's 2, that's 3. This is negative 1, negative 2, negative 3.
1, 2, 3, and this is the y-axis.
This would be negative 1. I think you get the idea. So we can graph each of these points.
I'll label it: negative 1 comma negative 1.
Let's do another one. That's this point. I'll do it in a different color this time.
And that brings us to financial resources, is how are we going to get this start-up off the ground? If you're doing a web, mobile, ??? seem quite possible that you could get the company started with your credit cards, friends and family, crowdfunding like quick starter, local angels that is investors who are not professional venture capitalists, but might make some small investments. Again, if all you need is a laptop and Amazon Web Services account, you could be up and running developing an app but just keep in mind that when you're asked to do the financial calculations, there might be great to actually code the app but how are you going to create customer relationships and get, keep, and grow your business, and so financial resources actually gets you back to thinking about other demand creation activities in customer relationships and the cost of your channel as well, so while you could get started here, it's interesting to start pre-computing what other amounts of capital I will need later on in the life cycle of my company.
Let's talk a little bit about what I find to be one of the more mysterious forces of the universe. Actually, I find all of the forces of the universe to be fairly mysterious, so let's talk a little bit about charge.
But when you really think about it, all charge means is that there's this property called charge, and we know that if something contains a positive charge-- and calling it positive is a little bit arbitrary. It's not like protons have a little plus written on them. We could have called them negative.
But when something has a positive charge and when something else has a positive charge, that they repel each other. We also know that if I had something else, another particle that happened to have a negative charge, and once again, the word "negative" being applied to this is completely arbitrary. They could have called it blue charge and red charge, but all we know is that when another object has the other charge-- in this case, we call it negative-- that's going to be attracted to a positive charge.
And to some degree, it seems a little bit more real than charge, because our brains are wired to in some way comprehend what mass is, but we're probably comprehending weight and volume more than mass, but we can think more about that at another time.
Charge is a little bit more abstract because, before we started rubbing amber into our hair, we really didn't experience much charge unless we got struck by lightning. So charge is a property that particles or objects have, and we know that there are two types of charge, which we've arbitrarily named positive and negative. And we know that like charges repel and opposite charges attract, or unlike charges attract, right?
Here's some code for finding the second largest name in that list. It starts off opening the file that has the year of birth 1995 data in it and instead of having just one max value that they're keeping track of we keep track of the max name and the maximum value we've seen so far and the second highest name and value that we've seen so far. I initialized to zero because all of the values in this file are greater than zero, actually five or greater, and then, we loop through the lines in the file, for each line, we pull out the name, sex, and count using rsplit and make sure that that count is not a string anymore but an integer, and we check to make sure the sex is female because that's the way we're doing it for this question.
Hi, my name is Jason Cornwell and I'm a User Experience Designer on Gmail.
We've been hard at work to update Gmail with a new look and I'm excited to share with you some of the biggest improvements. If you prefer a specific display density, you can easily set that as well.
Conversations in Gmail have been redesigned to improve readability and to feel more like a real conversation. We've also added profile pictures so you can see who said what. You can also create a filter from the search box.
To get a handle on how to best find shortest paths in a graph, it's going to help to compare a little bit between the kinds of depth first search algorithms that we were looking at with the kinds of breadth first search algorithms that we're going to need to look at. So let's consider what the check_connection algorithm that we were just talking about does if it's given this graph, G, and we ask it to check the connection between i and n. The flow of control is when we do check_connection on i and n, checking to see whether i and n are connected in the graph, the way that it proceeds is it starts off at i then visits the neighbors of i in some order.
My big idea is a very, very small idea that can unlock billions of big ideas that are at the moment dormant inside us. And my little idea that will do that is sleep.
(Laughter) (Applause) This is a room of type-A women. This is a room of sleep-deprived women.
(Applause) And we women are going to lead the way in this new revolution, this new feminist issue. We are literally going to sleep our way to the top, literally.
(Laughter) (Applause) Because unfortunately for men, sleep deprivation has become a virility symbol. I was recently having dinner with a guy who bragged that he had only gotten four hours sleep the night before.
(Laughter) There is now a kind of sleep deprivation one-upmanship. Especially here in Washington, if you try to make a breakfast date, and you say, "How about eight o'clock?" they're likely to tell you, "Eight o'clock is too late for me, but that's okay, I can get a game of tennis in and do a few conference calls and meet you at eight."
(Applause) While all the brothers were busy just being hyper-connected 24/7, maybe a sister would have noticed the iceberg, because she would have woken up from a seven-and-a-half- or eight-hour sleep and have been able to see the big picture. So as we are facing all the multiple crises in our world at the moment, what is good for us on a personal level, what's going to bring more joy, gratitude, effectiveness in our lives and be the best for our own careers is also what is best for the world.
(Applause)
Humans in the developed world spend more than 90 percent of their lives indoors, where they breathe in and come into contact with trillions of life forms invisible to the naked eye: microorganisms. Buildings are complex ecosystems that are an important source of microbes that are good for us, and some that are bad for us. What determines the types and distributions of microbes indoors?
I want to start off by saying, Houston, we have a problem. We're entering a second generation of no progress in terms of human flight in space. In fact, we've regressed.
(Laughter) What we're looking forward to is -- (Applause) what we're looking forward to is not only the inspiration of our children, but the current plan right now is not really even allowing the most creative people in this country -- the Boeing's and Lockheed's space engineers -- to go out and take risks and try new stuff. We're going to go back to the moon ... 50 years later?
"Ooh, hey, I can do that." There's only a few people that have flown in early 1908. In four years, 39 countries had hundreds of airplanes, thousand of pilots. Airplanes were invented by natural selection.
(Laughter) If you look at what happened -- this little black line is as fast as man ever flew, and the red line is top-of-the-line military fighters and the blue line is commercial air transport. You notice here's a big jump when I was a little kid -- and I think that had something to do with giving me the courage to go out and try something that other people weren't having the courage to try.
Of course, one of them is around the world Voyager. I founded another company in '82, which is my company now. And we have developed more than one new type of airplane every year since 1982.
We retreated in '98 back to something that was developed in '56. What? The most impressive spaceship ever, I believe, was a Grumman Lunar Lander.
In 2003, everyone that the United States sent to space was killed.
There were only three or four flights in 2003.
In 2004, there were only two flights: two Russian Soyuz flights to the international manned station. And I had to fly three in Mojave with my little group of a couple dozen people in order to get to a total of five, which was the number the same year back in 1961. There is no growth.
(Laughter) OK. My critics say, "Hey, Rutan's just spending a lot of these billionaires' money for joyrides for billionaires.
(Laughter) Not the bank's computer or Lockheed's computer, but the home computer was for games. For a whole decade it was for fun -- we didn't even know what it was for.
The military fighters had a -- highest-performance military airplane was the SR71. It went a whole life cycle, got too rusty to fly, and was taken out of service. The Concorde doubled the speed for airline travel.
100 million bucks -- hey, I can go to the moon. But, you know, would you have thought back in the '60s, when the space race was going on, that the first commercial capitalist-like thing to do to buy a ticket to go to the moon would be in Russian hardware? And would you have thought, would the Russians have thought, that when they first go to the moon in their developed hardware, the guys inside won't be Russians?
(Applause)
We humans have imagined many things and in most of them we have imagined a reflection of ourselves like, the different aliens we see today all such aliens have human characteristics they talk, they breathe, they move they have hair Just like our ancestors imagined god their god had heart, it had ears to listen and it listened with ts ear, it means, our god cannot hear the voices inside our hearts, it required an ear, that too only in human frequency - sound.
We're asked to subtract and simplify the answer, and we have 8/18 minus 5/18. So subtracting fractions is very similar to adding fractions. If we have the same denominator, the denominator in the difference is going to be the same as the denominators in the two numbers that we're subtracting, so it's going to be 18.
18 divided by 3 is 6, so you get 1/6. And just to see this visually, let me draw 18 parts. Let me draw 18 parts here.
In the last video we got some practice adding what we could consider smaller numbers. For example, if we added 3 + 2 we could imagine that if maybe I had three lemons -- 1, 2, 3 -- and if I were to add to those three lemons maybe two lime-- Is it lime or limes? Let's just -- Well, two green lemons -- or two more tart pieces of fruit
0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 -- Let's go pretty high. 12 --
2 pennies, plus 1 dime. Plus 1 ten. Plus 1 dime.
We do the exact same thing as before. We just look at the 1s place only. So we look at 8 + 3.
So 8 + 3 = 11.
I have spent my entire life either at the schoolhouse, on the way to the schoolhouse, or talking about what happens in the schoolhouse. (Laughter) Both my parents were educators, my maternal grandparents were educators, and for the past 40 years, I've done the same thing.
"They don't pay me to like the kids. They pay me to teach a lesson. The kids should learn it.
Well, I said to her, "You know, kids don't learn from people they don't like." (Laughter) (Applause)
So I came back to class the next day and I said, "Look, guys, I need to apologize. I taught the whole lesson wrong.
"You were chosen to be in my class because I am the best teacher and you are the best students, they put us all together so we could show everybody else how to do it." One of the students said, "Really?" (Laughter)
You see, "-18" sucks all the life out of you. "+2" said, "I ain't all bad." For years, I watched my mother take the time at recess to review, go on home visits in the afternoon, buy combs and brushes and peanut butter and crackers to put in her desk drawer for kids that needed to eat, and a washcloth and some soap for the kids who didn't smell so good. See, it's hard to teach kids who stink.
We're now ready to talk about one of the most famous events in all of world history that really was the trigger for World War 1 or the Great War as it was called back then. So this is a little bit of backdrop. In 1908, the austro-hungarian empire formally annexes
As a little bit more backdrop: as the Ottomans were being pushed out of the Balkans, it helped to bring about more hope of unifying the Yugoslavic people; the "Southern Slavic" people.
When people talk about Yugoslav, They are literally talking about the Southern Slavs. That literally means 'Southern'.
And when they're there, there is a scheme to assassinate them from a group called 'the young Bosnians' who have ties to 'the black hand', which is a kind of nationalistic group that has ties to
- these things are all very shady - but it has has ties to elements in the Kingdom of Serbia. They attempt to assassinate archduke Franz Ferdinand. It is actually a fascinating story, because the initial assassination attempt is completely botched.
Gavrilo Princip gets up, puts his sandwich down, and starts walking over to where he sees archduke Franz Ferdinand and Sophie's car going. The drivers once they realized that they had made a mistake, that they had taken a less safe route, they try to back up which makes things even worse because then the car starts stalling.
Gavrilo Princip just walks up to the car and is able to shoot archduke Franz Ferdinand and Sophie. Just to give you a sense of how important this is: archduke Franz Ferdinand of Austria is the heir, he is the nephew of Franz Joseph, who was the ruler of Austria-Hungary, and so he is the heir to the empire.
And he gets assassinated by Gavrilo Princip. so...
Franz Ferdinand Assassinated by Gavrilo Princip.
And we have right over here a picture of right after Gavrilo Princip...
- I believe this is him over here - right after he was arrested. Just to get a little sense of how this was tied to this whole Yugoslavian nationalistic movement, this is what he said once he was arrested:
"I am a Yugoslav nationalist..."
"...aiming for the unification of all Yugoslavs, ..." "...and I do not care what form of state..." "...but it must be free of Austria."
Bosnia-Herzegovina with Serbia maybe eventually Croatia with Bosnia-Herzegovina and Serbia, this assassination as we will see in the next video is the trigger for all of World War 1. And the reason why it triggers it is because... -- well there's many things you can cite; you could argue that many of the empires in Europe are already militarizing, already had a desire for conflict.
But then you also had all of these alliances that essentially allowed the dominoes to fall in all of Europe and because they had these empires essentially much of the world to be at war with each other
Imagine generating an Erdos-Renyi Graph with n = 256 and p = 0.25. On average, how many edges will it have?
One of my favorite cartoon characters is Snoopy. I love the way he sits and lies on his kennel and contemplates the great things of life. So when I thought about compassion, my mind immediately went to one of the cartoon strips, where he's lying there and he says,
"I really understand, and I really appreciate how one should love one's neighbor as one love's oneself. The only trouble is the people next door; I can't stand them." This, in a way, is one of the challenges of how to interpret a really good idea.
"Well, you know there's just so much out there -- I can't do anything, I'm not going to even begin to try." And there are some charity workers who call this compassion fatigue.
"I'm an idiot. God wants bread? God, the one who rules the entire universe, wants my bread?"
"is answering God's plea that we should be compassionate. And God," he said to the poor man, "is answering your plea that people should be compassionate and give." He looked at the rich man.
"Don't you understand?" He said, "These are the hands of God."
So that is the way I feel: that I can only try to approach this notion of being compassionate, of understanding that there is a connectivity, that there is a unity in this world; that I want to try and serve that unity, and that I can try and do that by understanding, I hope, trying to understand something of the pain of others; but understanding that there are limits, that people have to bear responsibility for some of the problems that come upon them; and that I have to understand that there are limits to my energy, to the giving I can give. I have to reevaluate them, try and separate out the material things and my emotions that may be enslaving me, so that I can see the world clearly. And then I have to try to see in what ways
You may have heard about the Koran's idea of paradise being 72 virgins, and I promise I will come back to those virgins. But in fact, here in the northwest, we're living very close to the real Koranic idea of paradise, defined 36 times as "gardens watered by running streams."
Since I live on a houseboat on the running stream of Lake Union, this makes perfect sense to me. But the thing is, how come it's news to most people? I know many well-intentioned non-Muslims who've begun reading the Koran, but given up, disconcerted by its "otherness."
"as toilsome reading as I ever undertook, a wearisome, confused jumble."
(Laughter) Part of the problem, I think, is that we imagine that the Koran can be read as we usually read a book -- as though we can curl up with it on a rainy afternoon with a bowl of popcorn within reach, as though God -- and the Koran is entirely in the voice of God speaking to Muhammad -- were just another author on the bestseller list.
Yet the fact that so few people do actually read the Koran is precisely why it's so easy to quote -- that is, to misquote. Phrases and snippets taken out of context in what I call the "highlighter version," which is the one favored by both Muslim fundamentalists and anti-Muslim Islamophobes. So this past spring, as I was gearing up to begin writing a biography of Muhammad,
(Laughter) So I read slowly.
(Laughter) I'd set aside three weeks for this project, and that, I think, is what is meant by "hubris" -- (Laughter)
-- because it turned out to be three months.
I did resist the temptation to skip to the back where the shorter and more clearly mystical chapters are. But every time I thought I was beginning to get a handle on the Koran -- that feeling of "I get it now" -- it would slip away overnight, and I'd come back in the morning wondering if I wasn't lost in a strange land, and yet the terrain was very familiar. The Koran declares that it comes to renew the message of the Torah and the Gospels.
"an interpretation." But all is not lost in translation. As the Koran promises, patience is rewarded, and there are many surprises -- a degree of environmental awareness, for instance, and of humans as mere stewards of God's creation, unmatched in the Bible.
Or take the infamous verse about killing the unbelievers. Yes, it does say that, but in a very specific context: the anticipated conquest of the sanctuary city of Mecca where fighting was usually forbidden, and the permission comes hedged about with qualifiers. Not "You must kill unbelievers in Mecca," but you can, you are allowed to, but only after a grace period is over and only if there's no other pact in place and only if they try to stop you getting to the Kaaba, and only if they attack you first.
(Laughter) This was perhaps the biggest surprise -- how flexible the Koran is, at least in minds that are not fundamentally inflexible. "Some of these verses are definite in meaning," it says,
"and others are ambiguous." The perverse at heart will seek out the ambiguities, trying to create discord by pinning down meanings of their own. Only God knows the true meaning.
(Laughter) Now this may be a way of saying "pure beings" -- like in angels -- or it may be like the Greek Kouros or Kórē, an eternal youth.
"a new creation in paradise" and that you will be "recreated in a form unknown to you," which seems to me a far more appealing prospect than a virgin.
(Laughter) And that number 72 never appears. There are no 72 virgins in the Koran.
Paradise is quite the opposite. It's not virginity; it's fecundity. It's plenty.
(Applause)
Applause
Lakshmi : So Kalki I wanna talk about identity Kalki :
Lakshmi: So, my last question to you Kalki You are the future, young you know you're part of the INK fellow's program
Yesterday worse than today, tomorrow better than today or something like that Basically you know, there's another day coming and you just need to keep going and you need to get better and I think that's it We're too busy judging other people or judging how we should be with other people rather than just concentrating on you know whats in front of us take a step, move forward, do something
For an art project, a pentagon made of construction paper is cut into five equal slices. Two of the slices are removed. Write the remaining portion of the pentagon as a fraction.
There you go. That's a pretty decent shot at a pentagon. So that's the pentagon made out of construction paper.
So let's get rid of two of these slices. Let's say we remove that slice up there. Let's say we remove the slice right next to it right over there.
So what are the remaining slices? Well, I have this slice right there, that slice right over here and then this slice. So you have three slices remaining out of a total possible of how many?
Hi. This is Sal Khan. I just wanted to welcome you to the Khan Academy, where you're about to embark on your own personalized learning adventure - where our system is going to really customize according to your own needs.
What happens at the depth here? So, we keep dividing it in half until we get down to 1. We've already spoken about that.
But the good news is there really is no answer. As we get further on in the series of videos, we'll get to see how you end up choosing which is right for your company.
Welcome back. So where we left off is, there was 1,000 people who all needed, let's say, $1 million loans each. And they were all going to pay 10% on their loans.
So now I have all of the, you know, me-- that's a little smiley face. There's 1,000 of me, and we are now going to pay the 10%. We're now going to make all of our mortgage payments, the 10% payment, to this bank, this investment bank.
Planetary systems outside our own are like distant cities whose lights we can see twinkling, but whose streets we can't walk. By studying those twinkling lights though, we can learn about how stars and planets interact to form their own ecosystem and make habitats that are amenable to life. In this image of the Tokyo skyline,
So when we want to learn whether a planet is habitable, whether it might be amenable to life, we want to know not only how much total light it receives and how warm it is, but we want to know about its space weather -- this high-energy radiation, the UV and the X-rays that are created by its star and that bathe it in this bath of high-energy radiation. And so, we can't really look at planets around other stars in the same kind of detail that we can look at planets in our own solar system. I'm showing here Venus, Earth and Mars -- three planets in our own solar system that are roughly the same size, but only one of which is really a good place to live.
For this quiz, I just want to make sure that you understand the definition of the clustering coefficient. So I'd like you to compute the clustering coefficient for a node in this graph. Now, this graph is inspired by the flight graph for a major imaginary airline in the United States.
Raleigh-Durham, Philadelphia, and Providence. This is just kind of a random selection of big cities in the US, but with emphasis on places I've lived. As usual, I've drawn edges between cities.
So, we can define a recurrence relation for this particular tree generation process or graft generation process that matches the recursive structure of the generating routine. We have a graph with 1 node, it's going to have 0 edges, by the way that this generation process happens. If we have a graph with n nodes, what is it going to do?
To generate a graph with n nodes, it 1st breaks that sub problem into 2 things, where we work out the number of edges in a graph with n/2 nodes. but doing that requires working it out for n/4 nodes and so on. This goes on and on and on until we get down to a whole bunch of individual graphs, each of which has 1 node. That's where the recursion bottoms out.
Our first guest is Peter Winkler who is a world expert in discrete mathematics and combinatorics and a mathematics and computer science professor at Dartmouth College. His work has had substantial impact on the design of algorithms and theoretical computer science. He is also a celebrated collector of mathematical puzzles, having written two books on the subject as well as a monthly column for the communications of the ACM.
Now, since I've started off every unit with a mathematical magic trick, I thought Peter would be an excellent person to beguile us with a few fascinating tricks of his own. I have a puzzle from my book about a spy who is trying to convey information to her control, but the only means she has for conveying information is that there is a 15-bit radio broadcast every morning, and she has the ability if she wishes to alter 1 bit of that broadcast.
"Look at this radio broadcast after I've altered it, and add up the nimbers of all the positions of where you see a 1." Now, when the spy sees the radio broadcast, she looks at what the nimbers currently add up to. Say the nimbers currently add up to 1010.
In problem 4, we've given a list of n numbers and our task is to find the mode, within time Theta (n). And there's a lot of different ways to do this and - so, what I've done is, I've gone through and basically written five different ways of doing it.
Another thing you could do is you can use the - the built-in max feature of Python and again when we're just doing incremental changes, we're going to use the default dictionary again, we're going to increment the value, but instead of keeping track as we go through, what we're going to do instead is do see this max at the end, with a little lambda function that basically returned the number of appearances that a given value had in the list and then returning the maximum key. And to show you that you can make it even more compact, you can actually use the set feature of Python.
All right. So let's think about this. So we have either ordered list or unordered list.
In the unordered case, inserting into the list is so easy. We just stick it into the end and just extend the list a little bit. So that's a constant time operation.
Now we're ready for the final step of parsing our map data. We want to keep track of each tile set that our map loads. So we need to keep an array of available tile sets in our tile map class.
All right, so I've got an interesting collection of names here. I had to include Michael because it is a relevant name to me, but in fact, in 1995, it was the most popular name given in the US, more popular than any of the names given to any of the women and in fact, Matthew is the second highest male name, but I didn't ask for male names, I asked for female names.

[Narrator] A lot of us are wondering what is all this technology doing to our brains?
[Phone ringing; beeping] I mean, we know that the brain changes throughout life based on experiences. In fact, watching this movie is reshaping connections in your brain right now.
But since we humans are the ones creating and using this technology, maybe a better question to ask is how are we shaping our brains?
[Brain Power]
There is so much about the brain that we don't know, but there are some things we do know. You see, not long after we humans began thinking, we began thinking about ways to understand our own brains. One strategy thinkers have used throughout history is to compare the brain to the newest technology of their day.
"How do you imagine the brain?" It was amazing, like all these neurons firing ideas and images back to us from all over the world. [♪ Music ♫]
And it was very clear. The Internet, the most advanced technological system in the world, is such a strong framework to help understand the human brain, the most advanced biological system in the world. But then we thought about it a bit more, and since the Internet is in such a young, developmental stage, rapidly growing, constantly changing, forming billions of new connections all over the world, then maybe a stronger framework would be to compare it to a child's brain, which is in a similar stage of development, rapidly growing, constantly changing, and making billions upon billions of connections between different parts of the brain.
[♫ Music ♪]
Well, the Internet has over a 100 trillion links, and an adult's brain has 300 trillion links. But get this: A child's brain has a quadrillion connections-- 10 times the number of connections of the entire Internet.
"Send us videos of your favorite ways to engage with the children in your life." [Piano music ♫]
During these early years, a child's brain makes as many connections as possible, and then it begins pruning the ones that aren't used and strengthening the ones that are. A dynamic process that continues throughout life. But since a child's brain is activated by everything it encounters, it can also be overwhelmed, which causes stress.
While the brain can change throughout the rest of life, these early years are fundamental in building a strong foundation for curiosity, creativity, and adaptability. [♪ Music ♪]
And if we say that the Internet is in the same critical stage of early development, making as many connections as possible, we also need to be mindful of how we're building its foundation. Just like every interaction creates new connections in a child's brain, every e-mail, tweet, search, or post is creating and strengthening connections in our global brain, literally changing the shape of the Internet that we, as billions of people all over the world, are developing together.
For both the Internet and a child's brain, the connections we pay most attention to will be strengthened, while the ones we use less will be pruned. [♪ Music ♪]
So how do we nurture both of these growing, interconnected networks to set a course for a better future? By paying attention to what we are paying attention to. Attention is the mind's most valuable resource.

Hi. I'm Kevin Allocca, I'm the trends manager at YouTube, and I professionally watch YouTube videos. It's true.
And similar to "Double Rainbow," it seems to have just sprouted up out of nowhere. So what happened on this day? Well it was a Friday, this is true.
All right, we're on problem number 8. They ask us which equation is equivalent 5x-2(7x+1)＝14x So I'm guessing they just want to simplify this a little bit and see if we get to one of these choices.
Plus -2 times 17x is minus 14x. minus 14x And then -2 times 1 is minus 2 is equal to 14x. And let's see, on all of these choices they have 14x on the right hand side.
So this simplifies to 5x, plus -14, so that's -14x minus 2 is equal to 14x. So we have 5x-14x. What's 5-14?
It's what? -9, right? -9x-2＝14x
-20x is equal to 6 minus-- maybe you might have been tempted to say, oh, 6 minus 3, that's 3, and then distribute it. Remember, order of operations. Multiplication comes first.
I really should have simplified this 6 minus 3 but I didn't want to do too much in one step. So 8＝3+29x, and then if we subtract 3 from both sides here we get 8 minus 3 is 5. That 3 goes away and you get 29x and that is choice C. 29x＝5.
Next question, problem number 10. And I should be careful that you don't think that all of this stuff is for this problem.
The total cost, c, in dollars of renting a sailboat for n days is given by this equation. If the total cost was $360 for how many days was the sailboat rented? So they're giving us c. c is $360.
I would subtract 2x from both sides, and it looks like that's what they attempted to do because they got rid of this 2x, right? On the right-hand side they went from 2x+35 to just 35 so somehow they got rid of this 2x and the only way to get rid of it is to subtract 2x from both sides. Right?
So even though they were trying to get rid of this 2x and they should have subtracted 2x from both sides they inadvertently added 2x here so they said 2x+3x＝5x.
Well, that was wrong. You have to subtract. And you're just left with x+15 ＝35.
A 120-foot-long rope is cut into 3 pieces. The first piece of the rope let me draw. This is begging for a diagram.
But they want to know what is the length of the longest piece of rope? the longest piece of rope Well, the longest piece of rope is clearly piece 3. Right?
All right. Don't want to rush them, though. Let's see.
1,750? Yeah, because 1,500 minus 750 is 750. 1,750.

So when a number is going to be a factor of 154 is if we can divide that number into 154 and not have a remainder. Or another way of thinking about it-- a number is a factor of 154 if 154 is a multiple of that number. So let's look at each of these and see which of these we can rule out or say is a factor.
-CHAPTER 15 'I did not start in search of Jim at once, only because I had really an appointment which I could not neglect. Then, as ill-luck would have it, in my agent's office I was fastened upon by a fellow fresh from Madagascar with a little scheme for a wonderful piece of business.
Not a vestige of the Argonauts ever turned up; not a sound came out of the waste.
Finis! The Pacific is the most discreet of live, hot-tempered oceans: the chilly Antarctic can keep a secret too, but more in the manner of a grave. 'And there is a sense of blessed finality in such discretion, which is what we all more or less sincerely are ready to admit-- for what else is it that makes the idea of death supportable?
Finis! the potent word that exorcises from the house of life the haunting shadow of fate. This is what--notwithstanding the testimony of my eyes and his own earnest assurances-- I miss when I look back upon Jim's success.
A blustering sigh passed; furious hands seemed to tear at the shrubs, shake the tops of the trees below, slam doors, break window-panes, all along the front of the building. He stepped in, closing the door behind him, and found me bending over the table: my sudden anxiety as to what he would say was very great, and akin to a fright. "May I have a cigarette?" he asked.
"Rain or shine," he began brusquely, checked himself, and walked to the window. "Perfect deluge," he muttered after a while: he leaned his forehead on the glass. "It's dark, too."
'He came in at last; but I believe it was mostly the rain that did it; it was falling just then with a devastating violence which quieted down gradually while we talked. His manner was very sober and set; his bearing was that of a naturally taciturn man possessed by an idea. My talk was of the material aspect of his position; it had the sole aim of saving him from the degradation, ruin, and despair that out there close so swiftly upon a friendless, homeless man; I pleaded with him to accept my help; I argued reasonably: and every time I looked up at that absorbed smooth face, so grave and youthful, I had a disturbing sense of being no help but rather an obstacle to some mysterious, inexplicable, impalpable striving of his wounded spirit.
"You say you won't touch the money that is due to you."...He came as near as his sort can to making a gesture of horror. (There were three weeks and five days' pay owing him as mate of the Patna.)
"Well, that's too little to matter anyhow; but what will you do to-morrow? Where will you turn? You must live ..."
"That isn't the thing," was the comment that escaped him under his breath. I ignored it, and went on combating what I assumed to be the scruples of an exaggerated delicacy. "On every conceivable ground," I concluded, "you must let me help you."
"The money ..." he began. "Upon my word you deserve being told to go to the devil," I cried, forcing the note of indignation. He was startled, smiled, and I pressed my attack home.
'He lifted his head. The rain had passed away; only the water- pipe went on shedding tears with an absurd drip, drip outside the window. It was very quiet in the room, whose shadows huddled together in corners, away from the still flame of the candle flaring upright in the shape of a dagger; his face after a while seemed suffused by a reflection of a soft light as if the dawn had broken already.
So computational complexity is the problem of actually finding the hardness of problems and from the prospective of a theoretician who studies complexity theory, the stuff that we've been doing so far talking about devising algorithms and proving their running times, that's just part of the story, that's just upper bound determination. There's a whole other set of work that has to go into finding lower bounds on the hardness of problems and that requires very different techniques from the kinds that we've talking about up to this point. So it's worth pointing out what theoreticians often really like to do is that they find an upper bound for the hardness of their problem and they can find a lower bound that matches it, then you know exactly the complexity of the problem.
Evan from Norway has asked me to do another u substitution problem, and I like these because it gets my momentum going for doing other things that maybe take a little bit more preparation. And the problem he sent me-- and I hope I pronounced his name right-- was the indefinite integral of sin of x over the cosine of x squared dx. This it also be written as-- he wrote it in email, so I don't know how he exactly saw it, but it can also be written as sin of x over cosine squared of x.
And then we can multiply both sides by dx, and you get du is equal to minus sin of x dx. I just multiplied both sides by dx. And then up here we have sin of x dx.
To take the antiderivative, we raise u-- it was to the minus 2 power, let's raise it to 1 power higher than that-- so minus 2 plus 1 is minus 1. So it's u to the minus 1 power, and then you want to divide by minus 1, and I'll do it explicitly here. Minus one.
As I was describing it before, for each node we do this test to find the shortest distance so far. That's a heap operation--there's n things in the heap, so this is a logn operation. So this altogether is going to get run once for each node--so this part of the algorithm actually takes time and logn.
Just I'll mention as an aside, there're some very clever data structure work that's been done by Fredman and Tarjan, the same Tarjan as before, that allows this actually to be decreased using a very special kind of heap that allows the running time to become nlogn+m. We need at least m just to visit all the edges. So this is a pretty remarkable result.
Now that you've been introduced into some of the other functions that we can take a derivative of, we can now apply them using the chain and the product rule. So let's do some fun derivatives. And I think derivatives is all about exposure, it's all about practice.
Good morning everybody. I work with really amazing, little, itty-bitty creatures called cells.
"We are what we eat," could easily be described as, "We are what our cells eat." And in the case of the flora in our gut, these cells may not even be human. But it's also worth noting that cells also mediate our experience of life.
Now the other thing is that in a resegmented market and again we use Southwest as a low-cost entry or whole foods as a unique niche supplier via positioning and what you really want to start asking is what factors can you eliminate that your industry has long competed on or what can you reduce below the industry standard or raise above the industry standard or what can be created that the industry has never offered? Now what's interesting is if you look at the chasm between your early adopters, your early evangelists and the mainstream market in a resegmented market this is what Moore was kind of talking about called the chasm. There really is a gap between what these people want and a gap between their needs.
The last question asked, what is the maximum clustering coefficient for a node in B? Here's the formula for a clustering coefficient. If you look at any node in the left side say the middle one.

Finding things like the max of a list or the min or the second largest or the second to last smallest, they are all examples of what are called order statistics. Statistics summaries of the values in a list that depend on the order that they are sorted. This notion is generalizing min and max, so the min can be expressed as order statistic 1.
The Story of Solutions (Why making real change starts with changing the game) with Annie Leonard Do you have one of these, of course not this thing is five years old now everyone's got on of these.
Can you imagine how much genius and focus it took to turn a music player into a hand-held computer, phone, GPS, remote control for everything in life in just five years. Seriously The thousands of people who made this thing had to solve thousands of problems that literally could not have been solved five years ago.
That's what economists call growth. So we take all the money spent on stuff that makes life better and all the money spent on stuff that makes life worse and we add it together into one big number called GDP. Were told that a bigger GDP means we're winning
What if we built this game around goal of better.
Better education, better health, better stuff. A better chance to survive on this planet.
That's what we all want. right?
So shouldn't that be what winning means? Changing the goal of the entire economy is a huge task. Of course we can't do it all at once.
By itself no, but in combination with millions of others working on game-changing solutions that they care about, YES. Together these solutions are beginning to turn the tide.
Whenever I'm asked to join in a solution I want to know if it's transformational will it change the goal? To figure it out I use the word GOAL I want to know that it G- gives people more power taking power back from corporations to build democracy.
I'm in. And they're popping up everywhere. Like the Evergreen cooperatives in Cleveland.

Bike share programs in major cities, online platforms that let us share everything from our cars to our homes to camping gear. In my town the public library system lends out tools.
There's just no reason that every house needs its own power drill, crème brûlée torch, scanner, wheelbarrow, a bike pump, when we can share. As transformational solutions like these gain traction we will reach a tipping point. If we keep focused on the new goal of better.
So the question is, what's the purpose of the minimum viable product? It turns out that the answer is pretty specific. You want to test the ability of some portion of your product and meet minimal customer needs and that might change over time but as the MVP slowly grows as your confidence in what the customer archetype is.
Well, I had to stop that last presentation because I ran out of time. But now we can start up right where we left off.
You could look at it two ways. When the run is three, the rise is negative four. So rise we went down by negative four, we ran three, and you can keep doing that on the line and you'll keep ending up on the line.
The y-intercept is right here. That's where you intersect the y-axis at the point. And we would know exactly what that point is.
Let's put the graph back there and I'm going to do another random points. I'm going to go a little faster this time. So let's say I had negative eight comma five and I had-- let me think of a good one-- two comma-- I'm just going to make up a number. two comma, let's say zero.
Oh my God. I thought I was using the line tool. That's horrendous.
Let's take this as a starting point. We'll get five minus zero. y sub one minus y sub two. Over x sub one-- minus eight minus two.
Imagine, if you will -- a gift. I'd like for you to picture it in your mind. It's not too big -- about the size of a golf ball.

Well, that's kind of an obvious statement up there. I started with that sentence about 12 years ago, and I started in the context of developing countries, but you're sitting here from every corner of the world. So if you think of a map of your country,
"These are places where good teachers won't go." On top of that, those are the places from where trouble comes. So we have an ironic problem -- good teachers don't want to go to just those places where they're needed the most.
I started in 1999 to try and address this problem with an experiment, which was a very simple experiment in New Delhi.
I basically embedded a computer into a wall of a slum in New Delhi. The children barely went to school, they didn't know any English -- they'd never seen a computer before, and they didn't know what the internet was. I connected high speed internet to it -- it's about three feet off the ground -- turned it on and left it there.
So at the end of it, we concluded that groups of children can learn to use computers and the internet on their own, irrespective of who or where they were. At that point, I became a little more ambitious and decided to see what else could children do with a computer. We started off with an experiment in Hyderabad, India, where I gave a group of children -- they spoke English with a very strong Telugu accent.
"I don't know, actually."
(Laughter) And I left.
(Laughter)
Two months later -- and this is now documented in the Information Technology for International Development journal -- that accents had changed and were remarkably close to the neutral British accent in which I had trained the speech-to-text synthesizer. In other words, they were all speaking like James Tooley.
(Laughter) So they could do that on their own. After that, I started to experiment with various other things that they might learn to do on their own.
I got an interesting phone call once from Columbo, from the late Arthur C. Clarke, who said, "I want to see what's going on." And he couldn't travel, so I went over there. He said two interesting things,
"A teacher that can be replaced by a machine should be."
(Laughter) The second thing he said was that,
"If children have interest, then education happens." And I was doing that in the field, so every time I would watch it and think of him.
(Video) Arthur C. Clarke: And they can definitely help people, because children quickly learn to navigate the web and find things which interest them. And when you've got interest, then you have education.
(Video) Boy: ... just mention, I play games like animals, and I listen to music. SM:
(Laughter) And indeed they had. I mean, if there's stuff on Google, why would you need to stuff it into your head?
(Laughter) So I left them with it. I came back after two months, and the 26 children marched in looking very, very quiet.
"Well, how long did you practice on it before you decided you understood nothing?" They said, "We look at it every day." So I said, "For two months, you were looking at stuff you didn't understand?"
(Laughter) (Applause) (Laughter) It took me three years to publish that. It's just been published in the British Journal of Educational Technology.
"It's too good to be true," which was not very nice. Well, one of the girls had taught herself to become the teacher. And then that's her over there.
Remember, they don't study English.
I edited out the last bit when I asked, "Where is the neuron?" and she says, "The neuron? The neuron," and then she looked and did this. Whatever the expression, it was not very nice.
(Laughter) Approximately 5,000 miles from Delhi is the little town of Gateshead. In Gateshead, I took 32 children and I started to fine-tune the method.
(Laughter) (Applause) The children enthusiastically got after me and said,
"Now, what do you want us to do?" I gave them six GCSE questions. The first group -- the best one -- solved everything in 20 minutes.
Ask Jeeves, etc. The teachers said, "Is this deep learning?" I said, "Well, let's try it.
200 of them volunteered immediately.
(Laughter) The deal was that they would give me one hour of broadband time, sitting in their homes, one day in a week. So they did that, and over the last two years, over 600 hours of instruction has happened over Skype, using what my students call the granny cloud.
(Video) Teacher: You can't catch me. You say it.
SM: Back at Gateshead, a 10-year-old girl gets into the heart of Hinduism in 15 minutes. You know, stuff which I don't know anything about.
Two children watch a TEDTalk. They wanted to be footballers before. After watching eight TEDTalks, he wants to become Leonardo da Vinci.
(Laughter) (Applause) It's pretty simple stuff. This is what I'm building now -- they're called SOLEs:
Fifteen minutes later --
next question: where is Calcutta?
This one, they took only 10 minutes.
I tried a really hard one then.
Who was Pythagoras, and what did he do?
There was silence for a while, then they said, "You've spelled it wrong.
It's Pitagora."
And then, in 20 minutes, the right-angled triangles began to appear on the screens. This sent shivers up my spine. These are 10 year-olds.
Text: In another 30 minutes they would reach the Theory of Relativity. And then?
(Laughter) (Applause) SM: So you know what's happened?
One billion children, we need 100 million mediators -- there are many more than that on the planet -- 10 million SOLEs, 180 billion dollars and 10 years. We could change everything. Thanks.
(Applause)
So just to summarize for a Google search, each had its own value proposition, but most importantly each had its own revenue stream, and one segment cannot exist without the other--that is, if you had users but you had no revenue, you'd be out of business over time. But if you had a revenue model but no users, there would be no reason for those advertisers to show up. Now this was an example of a 2-sited market.

With all the legitimate concerns about AlDS and avian flu -- and we'll hear about that from the brilliant Dr. Brilliant later today -- I want to talk about the other pandemic, which is cardiovascular disease, diabetes, hypertension -- all of which are completely preventable for at least 95 percent of people just by changing diet and lifestyle.
Now what can we do about this? Well, you know, the diet that we've found that can reverse heart disease and cancer is an Asian diet. But the people in Asia are starting to eat like we are, which is why they're starting to get sick
As we've already talked about as we exit the 1800s and we get to the early 1900s and we approach World War I the various powers of Europe are really on this race for empire; it was part of national prestige and it helped build national wealth But of the major powers Germany and Italy were relatively new as unified states. The British Empire had been building their empire for hundreds of years; the Germans on the other hand, even though they have a very old culture going back hundreds, or you could argue thousands of years, as a unified state they only existed since 1871.
Let's get started and learn how to convert percentages to decimals, and if we have time maybe we'll also learn how to convert decimals into percentages. So let's get started with what I think is a problem you probably already know how to do. If I said I have fifty percent.

And we know when the Calvin Cycle operates properly you'll have some carbon dioxide attached in one part of this enzyme. And then you'll have some RuBP, or maybe you could call it the proper word, ribulose-1 5-bisphosphate. And they're going to react.
In the last video I started with three of these and three of these so I ended up with six of these. But for every one of these you end up with two of these. This is the proper Calvin Cycle.
And then for every six of these that are produced-- and maybe I should write a three here, a three here and then I'll have six of these-- and for every six of these that are produced, five go back into the cycle to produce. So five PGALs, or glyceraldehyde 3-phosphate go back into the cycle to produce the ribulose bisphosphate.
RuBisCo does not only fix carbon dioxide. That instead of carbon dioxide we might have an oxygen molecule. We might have an oxygen molecule that jumps in here.
Which is that byproduct that gets processed later on. And then these five. You're going to have five here.

The next type of partnerships might be joint business development, joint promotion of complimentary products. One might be the dominant player. The best example of this in the computer industry was Intel.
We've been talking about the law of demand and how if we hold all else equal, a change in price, price goes up, the quantity demanded goes down and the price goes down, the quantity demanded goes up. So if you hold all else equal, ceteris paribus, we are just moving alone this curve depending on what price, but we started talking about what happens when you change some of those we've been holding equal. How does that change demand?
Chamba is a Free Movie project with social ownership next, right?
it is a new learning experience community of similar minded people not that, once more it is a learning experience a community of creative people [Jishnu from behind correcting a pronunciation mistake] Chamba is meeting of a bunch of creative people

Let's say that I go to the doctor's office. I hate when this happens, but every once in a while, I have to have my blood drawn. The reason I hate it is that I am kind of a chicken when it comes to getting my blood drawn.
90% of plasma is going to be nothing more than water. So that is interesting right, because the major part of blood is plasma, and the major part of plasma is water. So now you are seeing why it is that we always say "Make sure you drink a lot of water, make sure you are hydrated", because a big part of your blood itself is water.
line.
Just like that. This was the point over here, the point 3,9. And then this point up here is the point 3 plus delta x, so just some larger number than 3, and then it's going to be that number squared.
That's the coordinate of the second line. This looks complicated, but I just took this x value and I squared it, because it's on the line y is equal to x squared. So the slope of the secant
Hi, everybody. Welcome back. We're in unit 7, which is the last unit of our class.
And so we're in the last piece in detail is what gain are you creating. What are the benefits the customer expects, desires or surprise about. So again you're going to start with your hypothesis--"What makes the customer happy," or is that you're going to create savings and time or money and effort.
All right, we're on problem 44. And they said, which is the factored form of 3a squared minus 24ab plus 48b squared? And if this confuses you with a's and b's instead of an x there, I just like to think of in this case, this looks like an x squared.
3 is divisible by 3, 24 is divisible by 3 and 48 is divisible by 3. So we should be able to factor out a 3, so let's do that. So that is equal to 3 times a squared minus 8ab.
24 divided by 3 is 8 and there's a minus in front of it. Plus 48 divided by-- 3. My brain was getting ahead of me.
Minus 4, right? Minus 4, minus 4 is minus 8. Minus 4 squared is 16.
So this simplifies to 9t squared plus. Now what are we adding? Let's see.
8 goes into both of these, right? So let's factor out an 8. And actually, let's factor out a negative 8, and I'll show you why did that.
我们来练习一下直角三角函数比， 还有直角三角函数。 我们来求一下角theta（∠θ）的正弦和余弦。 先求余弦。 现在我们知道这是角theta （∠θ） And it is indeed a right triangle. So I'll give you a few seconds to think about that.
 This is the fourth of the five problems that
And, of course, this right here is 400. And this takes-- this right here takes 5 seconds. So in opposite directions they pass each other in 5 seconds.
How often do we hear that people just don't care? How many times have you been told that real, substantial change isn't possible because most people are too selfish, too stupid or too lazy to try to make a difference in their community? I propose to you today that apathy as we think we know it doesn't actually exist; but rather, that people do care, but that we live in a world that actively discourages engagement by constantly putting obstacles and barriers in our way.
It's an article about a theater performance, and it starts with basic information about where it is, in case you actually want to go and see it after you've read the article -- where, the time, the website. Same with this -- it's a movie review. An art review.
That's kind of wonderful, but we keep talking about the customer. Let me remind you what it looks like from their side and we'll be talking about customers in more detail in the next lecture, but why don't I just give you preview. In customer segments, we are also also looking for three things-- one is we are still trying to understand from this side what are the gains, what are the pains, but also what are jobs that customers want you to do.
So my name is Taylor Wilson. I am 17 years old and I am a nuclear physicist, which may be a little hard to believe, but I am. And I would like to make the case that nuclear fusion will be that point, that the bridge that T. Boone Pickens talked about will get us to.
And I assembled this in my garage, and it now lives in the physics department of the University of Nevada, Reno. And it slams together deuterium, which is just hydrogen with an extra neutron in it. So this is similar to the reaction of the proton chain that's going on inside the Sun.
So we're trying to find where 8.94 falls on this distribution. So it looks likes it's about here, so this z score is going to be really high. For this one the z score falls about here, which looks like it's still kind of in the center of the sampling distribution, so now if we calculate the actual z score...
We do more than ever in our browser. I know I use my browser more than I do my operating system. But with so many tasks, linear tabs just don't really cut it as a way to organize my online life anymore.
Welcome to Tab Candy. What I'd like to be able to do now is just drag my tabs into a set.
It's really that simple. Notice that when I zoom into a tab, only those tabs from that group are shown. This lets me focus.
With normal tabs, when I had 12 it was hard to manage. Here you can see that after browsing for a day, I have roughly 30 tabs. And even though the screen is the size of a netbook, I still have room to spare.
Good morning. Let's look for a minute at the greatest icon of all, Leonardo da Vinci. We're all familiar with his fantastic work -- his drawings, his paintings, his inventions, his writings.
(Laughter) And look what happens -- only three candidates remain that fit the bill. And here they are.
(Laughter) But there are 1,100, and very few artists have drawn so many faces. So I know a little about drawing and analyzing faces.
(Applause)
We have talked a little bit about the law of demand which tells us that, all else equal, if we raise the price of a product, then the quantity demanded for that product will go down. ..common sense. If we lower the price, the quantity demanded will go up. And we will see so in a few special cases for this.
[WRlTING] The price of other ebooks go up. So what will that do to our price quantity demanded relationship ?
If, people might say, oh you know that other book looks kind of comparable, if one is more expensive and one is cheaper, maybe I'll read one or the other. So, in order to make this statement, in order to stay along this curve, we have to assume that this thing is constant. If this thing changes, this is going to move the curve.
Let me write that, so this is going to shift Demand... [WRlTING] so the entire relationship: Demand to the right. [WRlTING]
I really want to make sure you have this point clear. When we hold everything else equal, we're moving along a given demand curve. We are essentially saying: the demand, the Price Quantity demanded relationship is held constant and we can pick a price and we'll get a certain quantity demanded.
It's always good to see the same problem done more than one way, and it's especially true with these ratio problems because they, in general, can be done in many, many different ways, and different types of ways gel with different people. So I just did a video on this where I said that the ratio of apples to oranges starts off at five to eight. And we take away fifteen.
So we're starting off with a apples and o oranges. So the ratio of a to o is equal to what? The ratio of a-- let me actually-- well, instead of trying to fit this whole problem into this part of the screen, let me just copy and paste this part, and do it at the bottom part of the screen.
So magic is a very introverted field. While scientists regularly publish their latest research, we magicians do not like to share our methods and secrets. That's true even amongst peers.
(Applause) (Music) Terribly sorry. I forgot the floor.
Wake up. Hey. Come on.
Okay. He figured out the system. (Music) (Laughter) (Applause) (Music)
(Music) All right. Let's try this.
(Music) (Laughter) (Music) Hey. (Music)
Just to illustrate this example, imagine we'd start up with some graph H. It's a little bit of a mess. There's a lot of edges in here but we're going to do is convert this to a new graph G, which is the complement of H, and so every place in H where there is an edge we leave the edge out, and every place where there is not an edge, we add an edge. For example, this node is not connected to this one or this one.
G, this new graph, which is the complement of H has an S-clique if and only if H has an S independent set. In fact, it's the same set of nodes. So here's our four clique for example.
Many believe driving is an activity solely reserved for those who can see. A blind person driving a vehicle safely and independently was thought to be an impossible task, until now. Hello, my name is Dennis Hong, and we're bringing freedom and independence to the blind by building a vehicle for the visually impaired.
(Laughter) We couldn't have been more wrong.
What NFB wanted was not a vehicle that can drive a blind person around, but a vehicle where a blind person can make active decisions and drive. So we had to throw everything out the window and start from scratch. So to test this crazy idea, we developed a small dune buggy prototype vehicle to test the feasibility.
(Applause) DH: So since we started this project, we've been getting hundreds of letters, emails, phone calls from people from all around the world.
So this sounds great. Partner sound wonderful but what could go wrong with this? Let's look at partnership risks.

Please grant me the absolute energy to see all of them in samayik by keeping the awareness of separation Please grant me the energy to do this samayik [I surrender] my mind-speech-body
Welcome back. In the last presentation I showed you that if I had the function f of x is equal to x squared, that the derivative of this function, which is denoted by f-- look at that, my pen is already malfunctioning. The derivative of that function, f prime of x, is equal to 2x.
This pen is horrible. I need to really figure out some other tool to use. The limit as h approaches 0 -- sometimes you'll see delta x instead of h, but it's the same thing-- of f of x plus h minus f of x over h.
So just another couple of rules. This might be a little intuitive for you, and if you use that limit definition of a derivative, you could actually prove it.
But if I want to figure out the derivative of, let's say, the derivative of-- So another way of-- this is kind of, what is the change with respect to x? This is another notation. I think this is what Leibniz uses to figure out the derivative operator.
This is the same thing as the derivative of f of x plus the derivative3 of g of x. That might seem a little complicated to you, but all it's saying is that you can find the derivative of each of the parts when you're adding up, and then that's the derivative of the whole thing. I'll do a couple of examples.
And I want to keep switching notations, so you don't get daunted whenever you see it in a different way. Let's say y equals 10x to the fifth minus 7x to the third plus 4x plus 1. So here we're going to apply the derivative operator.
One of the greatest things that could happen to a startup is a large company says,
"Hey! I want to invest in you, and I'm really interested in doing something with you guys." "We just don't want to be a supplier or a joint venture;
"we want to put money into your company." And I get all the time entrepreneurs who are going, "Yay! Look!"
"Oh, we want most favored nations clause,
"which means if you sign a deal with anybody else, we always want a better deal." Or my favorite is, "We want an exclusive for a year." Now, all these things sound great from the large company's perspective, but the question to ask yourself is, "What do they do for me building my business?"
"You want a 1-year exclusive or you want most favored nations." "It sounds like you actually want to buy us without actually spending the money, "because my goal is not to be a small subsidiary of your engineering department,
"my goal is to build a company your size." "And so we need to understand what's in it for both of us." And so I tend to try to understand, first of all, who's the sponsor and what's the motivation?
"because that's the only way I could grow more resources to make you successful."
"I'm happy to consider how you get an advantage,
"but you can't decide I'm your only supplier." So one of the ways I tend to deal with these is try to get sales deals, not investments. That is, to me it's a lot better to get a $10 million order from a company than a $10 million ownership position that they take because now they're your boss as well.
N² kind of beats everything here. So it's Θ(n²). It's order of n², as well as order of n³.
Θ(n²), O(n²), and O(n³). I'm going to add a little like for n³, this is valid because the big O notation is an upper bound. >>Upper bound. Okay. >>Yup.
In the last couple of videos we saw that we can describe a curves by a position vector-valued function. And in very general terms, it would be the x position as a function of time times the unit vector in the horizontal direction. Plus the y position as a function of time times the unit victor in the vertical direction.
A couple of mistakes—right on tactics—I just want to remind you about. I mentioned them earlier, but a common startup error on day one is let's price on cost. We know how much it takes to build our product.
(Music) (Music ends) (Applause) (Applause ends)
(Audience cheers) (Applause) Well, I'm not really sure why I'm here. (Laughter)
(Laughter) OK, this is sort of technology, but I can call it a 16th-century technology. But actually, the most fascinating thing that I found was that even the audio system or wave transmission nowadays are still based on the same principle of producing and projecting sound.
(Laughter) (Applause) Design -- I love its design. I remember when I was little, my mom asked me,
"Oh, Mr. Heifetz, your violin sounded so great tonight!" And Mr. Heifetz was a very cool person, so he picked up his violin and said,
"Funny -- I don't hear anything." (Laughter) Now I realize that as the musician, we human beings, with our great mind, artistic heart and skill, can change this 16th-century technology and a legendary design to a wonderful entertainment.
THlS IS YOUR LlFE. Do what you love and do it often. If you don't like something, change it.
If you don't like your job, quit!
If you don't have enough time, stop watching TV.
If you are looking for the love of your life, stop. They will be waiting for you when you start doing things you love. Stop over analyzing.
Open your mind, arms, and heart to new things and people. We are united in our differences.
Some opportunities only come once, seize them.
Travel often; getting lost will help you find yourself.
All emotions are beautiful.
When you eat, appreciate every last bite.
Ask the next person you see what their passion is. Share your inspiring dream with them.
Life is about the people you meet, and the things you create with them. So go out and start creating. Life is short.
(Applause) So I arrived by truck with about 50 rebels to the battle for Jalalabad as a 19-year-old vegetarian surfer from Jacksonville, Florida. (Laughter)
Long before that I had grown up with the war, but alongside weekend sleepovers and Saturday soccer games and fistfights with racist children of the Confederacy and religio-nationalist demonstrations chanting, "Down with communism and long live Afghanistan," and burning effigies of Brezhnev before I even knew what it meant. But this is the geography of self. And so I stand here today,
What we're going to do in this video is, through a bunch of examples, familiarize ourselves with the x,y-coordinate plane. And first we're going to just look at some points that are already plotted and figure out their coordinates. Then we're going to look at some coordinates and figure out where those points are.
D, x-coordinate negative 2. You see that right there. y-coordinate negative 2, as well. Let me get another color.
E, let's do the y-coordinate. We'll figure it out first, but you always have to write it second. It's negative 4.
Welcome back to recitation! In this video segment, we're going to look at the chain rule. Specifically we're going to answer a question that I've placed on the board.
I really am honored to be here, and as Chris said, it's been over 20 years since I started working in Africa. My first introduction was at the Abidjan airport on a sweaty, Ivory Coast morning. I had just left Wall Street, cut my hair to look like Margaret Mead, given away most everything that I owned, and arrived with all the essentials -- some poetry, a few clothes, and, of course, a guitar -- because I was going to save the world, and I thought I would just start with the African continent.
And the women said, "You know, Jacqueline, who in Nyamirambo is not going to buy doughnuts out of an orange bucket from a tall American woman?" And like -- (Laughter) -- it's a good point. So then I went the whole American way, with competitions, team and individual. Completely failed, but over time, the women learnt to sell on their own way.
"Well, you choose." And I said, "No, no, I'm learning to listen. You choose. It's your bakery, your street, your country -- not mine."
If you're here today -- and I'm very happy that you are -- you've all heard about how sustainable development will save us from ourselves. However, when we're not at TED, we are often told that a real sustainability policy agenda is just not feasible, especially in large urban areas like New York City. And that's because most people with decision-making powers, in both the public and the private sector, really don't feel as though they're in danger.
What troubled me was that this top-down approach is still around. Now, don't get me wrong, we need money. (Laughter)
(Applause) I have come from so far to meet you like this. Please don't waste me.
Let's learn to multiply. M U L T I P L Y. And the best way I think to do anything is just to actually do some examples, and then talk through the examples, and try to figure out what they mean.
Two plus three. That's equal to five. And if you need a bit of a review you could think of if I had two-- I don't know-- two magenta-- this color-- cherries.
Four plus two is equal to six. Now that's only one way to think about it. The other way we could have thought about this is we could've said, instead of having two added to itself three times, we could have added three to itself two times!
Two times three. It could also be rewritten as three two times.
So three plus three. And once again, you're like, where did this two go? You know, I had two times three and whenever you do addition, you see I have two-- oh, I don't know these-- well, I said cherries, but they could be raspberries or anything.
Where did the two go? Two in this case, in this scenario, is telling me how many times I'm going to add three to itself. But what's interesting is, regardless of which way I interpret two times three,
What's three plus three? That is also equal to six. And this is probably the first time in mathematics you'll encounter something very neat!
Three, plus three, plus three, plus three. And if we did that we get: Three plus three is six.
Six plus three is nine.
Nine plus three is twelve. And we learned, up here, in this part of the video, We learned that this same multiplication could also be interpreted as three times four.
Four plus four is eight.
Eight plus four is twelve. And in the U.S. we always say four times three, but you know, I've met people and a lot of people in my family they kind of learned in the-- I guess you could call it the English system.
How can, you know, three times some other number still be the same number? And think about what this means. You could view this as three ones.
Three plus zero, you've hopefully learned, is three. Because I'm adding nothing to the three. If you have three apples, and I give you zero more apples, you still have three apples.
What is four times zero? Well this is saying zero four times. So what's zero, plus zero, plus zero, plus zero?
Today, I'm going to take you through glimpses of about eight of my projects, done in collaboration with Danish artist Soren Pors.
Let's have the vector valued function r of s and t is equal to-- well, x is going to be a function of s and t.
So we'll just write it as x of s and t times the x unit vector, or i, plus y of s and t times the y unit factor, or j, plus x of s and t times the z unit vector, k. So given that we have this vector valued function, let's define or let's think about what it means to take the partial derivative of this vector valued function with respect to one of the parameters, s or t. I think it's going to be pretty natural, nothing completely bizarre here.
And the whole reason I did that, is if you take this side and that side, and multiply both sides times this differential ds, then what happens? The left hand side, you get the partial of r with respect to s is equal to this times ds. I'll do ds in maybe pink.
These 2 are going to be very valuable for us, I think, in getting the intuition for why surface integrals look the way they do.
[Sebastian Thrun - Research Professor, Stanford University - Fellow and VP, Google] So this is a really exciting event for us. We are launching now our new University Udacity.
[David Evans - Professor, University of Virginia] So welcome to the first class. This is a class that's going to introduce you to computer science, and we're going to do that by building a search engine. You're not expected to have any previous background in computing to take this class.
In activities of Seva - Satsang the raag-dwesh that have occurred between mahatmas This evening we will do [samayik] for our relatives and family members. Right now, all our fellow spiritual colleagues are next to us.
For instance [mahatmas] in the parking are not able to attend any of the satsangs, in many of the programs yet in those programs... despite that they also do a lot of penance and sometimes mahatmas get them all agitated regarding the car park they tell them, "we will park our car here and leave, what will you do?" hey help in the arrangements made... now they are conflicted The mahatmas have their own difficulties and the other mahatmas [in] parking seva have their difficulties So at what stage... which prakruti comes into conflict and the garbage arises [it could happen] while forming lines during meal times
Make us do this samayik with pure applied awareness of the Self (shudha upyog),
During the activities of this satsang right from the beginning up until now [in interactions] with any mahatma any kind of raag-dwesh (attachment-abhorrence) whatever types of mistakes have occurred as a person receiving seva or towards a person giving seva or while doing seva towards mahatmas whatever kind of raag-dwesh or mistakes may have occurred for all such mistakes to see them in samayik to do pratikraman be able to clean them
Please grant me the energy to do such a samayik We - all the mahatmas here Are praying with our hearts, that

Welcome to the lathe soft jaw video series Brought to you by Haas Automation Soft jaws offer several benefits not provided by hard jaws
The first side of this bearing housing has been completed We will show you our recommended soft jaw cutting methods As we make the jaws to hold the finished first side of this part
The clamping force on the part naturally decreases If the clamping pressure is set too high in an attempt to increase the clamping force The soft jaws will be distorted, actually decreasing grip force
Undersize jaws will grip along six edges, whereas oversize jaws will grip only along the center of each jaw Our program is set to cut at the nominal part diameter The soft jaws are clamping inwards on the boring ring at 100 psi
Once the jaws have been cut, make a shallow groove at the bottom of the jaws
Any work piece with sharp edges will now locate correctly against the jaw's back face Without this groove cut, a sharp-edged part will not locate correctly on the back face You will likely need to deburr the jaws when the machining is complete
In some cases, you won't be able to use the adjustable boring ring Because the part diameter is so large that the ring itself will block your cutting path That's exactly the case with this part here
Two step jaws are a good alternative to cutting two different jaw sets When part geometry is favorable, the larger pocket holds the uncut raw stock While the smaller pocket holds the half-finished part for the second operation
'Theory of mind' - Beginning about 15 years ago there's one property of human intelligence that science has got very interested in and it's called having a theory of mind. The best way to describe it is to describe a classic experiment with human children.
Sally has a ball she really likes and she's gonna put it in the basket which is right there in front of her, she hides the ball in the basket and here's Ann, Sally's friend, and they're playing together.
And Sally then says: 'I've gotta go to the bathroom, so I'm gonna leave the room.' And when she leaves the room
Ann takes the ball out of the basket and puts it in a green box, that she's got next to her.
Now Sally comes back into the room and she wants to play with the ball. And supposing you ask your sister:
Where is Sally going to look for the ball? If your sister is 3 years old, she'll say: 'In the box!'
As children get older, it happens pretty quickly: four, five or so, they go through the same test and you ask them the same question and they begin to say: 'Well Sally's gonna look for the ball in the basket, because that's where she thinks it is.' And the five or six-year old will say:
Thoughts are hidden, we don't see them. The only way we can imagine that thoughts are there and that they cause behaviour is if we have a theory about the way that the world works.
People have thoughts and the thoughts cause them what to do. Of course, in humans the theory of mind just pervades all of our life. We're for ever making a distinction between what people do and what they think we do.
'Yeah, she was nice to me yesterday, but does she really like me?' or 'I think that he doesn't know that you really do like him.' These things can get incredibly baroque, where you are attributing theory of mind back and forth to 3 other people and it's what we do in plays, it's what we do in our daily life all the time.
Let's take a look at now the web/mobile funnel. Now, what's really interesting is in the web/mobile funnel--the getting customers part of the funnel is actually quite simple, at least on first glance. We still have earned and paid media driving customers into the funnel.
Our next guest is Vukosi Marivate, who is currently a graduate student in computer science. He studies machine learning, but he's also a keen observer of the impact of technology on world cultures. He's been in several technology companies, and he's going to share some of his experiences with us.
Vukosi lives in South Africa, and he's currently going to graduate school in the United States to get his PhD in computer science. He has interned at a number of different companies, and this summer he interned with a company called Meebo that does some social networking. Can you tell me a little bit about Meebo?
[Vukosi Marivate, Graduate Student, Rutgers University]
Meebo was a company that did a couple of things. One was that they had a chat app. Another is that they also did advertising through something called Meebo bar.
So let's take a look at the value proposition in a little more detail and expand on those three components. The first one is your product, and as we said earlier,
"You need to understand which are part of your value proposition." Is it just hardware or software or books or are there really some manufacturing goods, some commodities, are you going to have intangible products that are part, copyrights and licenses that are part of your value proposition or are your going to have any financial products that is guarantees or insurance policies or maintenance contract or you're going to add some digital features to it as well. What we point here is that you realize that your product and service is not just the bits or hardware,
I am coming from a BPL (Below Poverty Line) family. That means, my father is a handloom weaver, my mother is a farm worker. I am studying up to only 9th standard.
"I want a feedback immediately." You see, whatever I make differently, I'll tell, "Shanti close your eyes and I put in her hand." This time, I'm doing the same.
"Yes, I want a feedback." "It's not possible to do. You will have to wait for some time." Then only I understand, oh, period means monthly once.
"What napkin you gave it to me? It is very nasty. I'll go back to my cloth using method," (says his wife, Shanti).
"Ask Anna (older brother) don't come to my home to talk about this subject." Then, I got an idea. Why not we contact medical college girls (students).
This way I checked. But, then also I was not satisfied. So these are all.. these steps are happening, the days are going, months are going...6 months.. 8 months.. 9 months..
Then, I send it to IlT (Indian Institute of Technology) for evaluation. Those days, I'm trying to patent. Because, little bit I'm getting
Welcome to this "How to Level a Haas Lathe" video
The leveling procedure has three steps: first, set the machine at the correct height to accommodate the coolant tank second, rough level front to back and side to side to promote proper coolant flow and finally, remove any twist in the base casting so the machine will cut accurately The tools need for this procedure are: a ratchet and 3/4" socket a 1 1/2" Wrench, Tape Measure and Haas Leveling Tool # T-2181 An ST-30 Turning Center is used to show the leveling procedure but the same principles apply to all the ST Series lathes
Note that any chip conveyor support screws or brackets should not be touching the ground until after the leveling procedure is complete If necessary, move the tailstock or 2nd spindle to the HOME position Prepare tool T-2181 by installing the mounting arm onto one of two slots the 45-degree slot is for ST Lathes
Jog the turret to the middle of X-axis travel Then jog the turret along the Z-axis towards the spindle getting to the end of Z travel if possible The shorter level vial will be parallel to the Z-axis and indicates the tilt of the machine from left to right
After adjusting the leveling screw, wait for at least 10 seconds for the bubble to stabilize Once settled, move the turret back across full Z-axis travel to the spindle side and note which direction the level is tilting If the bubble has not moved from the zero position the twist has been removed from the base
Continue to adjust the leveling screws until the bubble reads zero at both ends of Z-axis travel With the twist removed, it is time to lower the middle leveling screws into position Turn each middle screw and cast puck together making sure the puck is centered under the screw
Hi! I'm Michael Lipman. I'm going to be teaching CS215 for Udacity.
[Michael] I know a little bit, my kids use Facebook. . . I'm not sure, what to do with it exactly.
[Michael] Tween? I think I'm a tween.
[Michael] Oh! How many friends do you have on Facebook?
[Michael] And you know everybody? You know all those people?
[Michael] So what do you think a social network is? I don't know, just really any type of connection between two people on a community level.
[Michael] Do you think we have any friends in common? Um. . . probably not.
[Michael] That's what people say. Yeah.
[Michael] Do you think we have any friends in common? I don't know!
[Michael] We are now connected in the social network. I don't even know your name.
[Michael] Any friends that we would have in common? I'm going to guess, yes.
Ex-boyfriend! [Laughs] [Michael]
[Michael] So that's not a connection we can make. So, clearly walking around the streets talking to random people, is not a very efficient way to analyze your social network.
Excuse me! Can you tell us what you know about social networks?
Stunned, speechless. . . we'll have to find someone else.
Welcome to the presentation on the indefinite integral or the antiderivative. So let's begin with a bit of a review of the actual derivative. So if I were to take the derivative d/dx.
Is y just equal to x squared? Because we took the derivative, and clearly the derivative of x squared is 2x. But what's the derivative of x squared-- what's the derivative x squared plus 1?
Well, the derivative of x squared is still 2x. What's the derivative of 1? Right, derivative of 1 is 0, so it's 2x plus 0, or still just 2x.
Well the derivative of x squared plus 2 once again is 2x plus 0. So notice the derivative of x squared plus any constant is 2x. So really y could be x squared plus any constant.
A bolder color I think would make this more interesting. Let's say we said y is equal to the indefinite integral of-- let me throw something interesting in there.
And then it's x to the n minus 1. Well in this situation we're saying that x to the third is this expression, it's the derivative of y. This is equal to x to the third.
I would be willing to bet that I'm the dumbest guy in the room because I couldn't get through school. I struggled with school. But what I knew at a very early age was that I loved money and I loved business and I loved this entrepreneurial thing, and I was raised to be an entrepreneur, and what I've been really passionate about ever since -- and I've never spoken about this ever, until now -- so this is the first time anyone's ever heard it, except my wife three days ago, because she said, "What are you talking about?" and I told her -- is that I think we miss an opportunity to find these kids who have the entrepreneurial traits, and to groom them or show them that being an entrepreneur is actually a cool thing.
"Hey, this kid's a good speaker. He can't focus, but he loves walking around and getting people energized." No one said, "Get him a coach in speaking."
"Don't be an entrepreneurial type. Fit into this other system and try to become a student." Sorry, entrepreneurs aren't students.
"Where are you going to get the coat hangers to sell to the dry cleaners?" And I said, "Let's go and look in the basement." And we went down to the basement.
"Maybe I'll start contributing to my RSP now." Shit, you've missed 25 years. You can teach those habits to young kids when they don't even feel the pain yet.
[Just look at the people who built our country;] [Our parents, grandparents, our aunts, uncles ...] [They were immigrants, newcomers ready to make their mark]
[These people were thinkers, doers ...] [... innovators ...] [... until they came up with the name ...] [... entrepreneurs!] [They change the way we think about what is possible.]
[So seize the opportunity to create the job you always wanted] [Help heal the economy] [Make a difference.]
[But most importantly,] [remember when you were a kid ...] [when everything was within you reach,] [and then say to yourself quietly, but with determination:]
["It still is."] Thank you very much for having me.
Part B. For x is not equal to zero, express f prime of x as a piecewise-defined function. Find the value of x for which f prime of x is equal to negative 3. So the first thing you might be wondering is why did we even have to take out x is equal to zero from the...
Let's take a look at what we used to believe and then contrast it to what we now know. One of the biggest fallacies was believing that startups are just smaller versions of a large company. That everything you do in a large company, you'll do on day one of a startup.
If you're a coach or a mentor, what you're responsible for is spending 1 to 3 hours per week for every team. And you're going to be working with 1 to 4 teams for up to 3 weeks. We encourage you to meet up once a week in person and/or once a week online per team with Skype or Google Hangout.
I want to start with a story, a la Seth Godin, from when I was 12 years old. My uncle Ed gave me a beautiful blue sweater -- at least I thought it was beautiful. And it had fuzzy zebras walking across the stomach, and Mount Kilimanjaro and Mount Meru were kind of right across the chest, that were also fuzzy.
The bakery was completely wiped out, but the lessons for me were that accountability counts -- got to build things with people on the ground, using business models where, as Steven Levitt would say, the incentives matter. Understand, however complex we may be, incentives matter. So when Chris raised to me how wonderful everything that was happening in the world, that we were seeing a shift in zeitgeist, on the one hand I absolutely agree with him, and I was so thrilled to see what happened with the G8 -- that the world, because of people like Tony Blair and Bono and Bob Geldof -- the world is talking about global poverty; the world is talking about Africa in ways I have never seen in my life.
We took a lesson from IDEO, one of our favorite companies, and quickly did a prototyping on this, and took Jacqueline into the area where she lives. She brought 10 of the women with whom she interacts together to see if she could sell these nets, five dollars apiece, despite the fact that people say nobody will buy one, and we learned a lot about how you sell things. Not coming in with our own notions, because she didn't even talk about malaria until the very end.
My name is Arvind Gupta, and I'm a toymaker. I've been making toys for the last 30 years. The early '70s, I was in college.
The slogan of the early '70s was "Go to the people. Live with them; love them. Start from what they know.
This is a toy which is made from paper. It's amazing. There are four pictures.
And this costs very little money to make -- great fun for children to do. What we do is make a very simple electric motor. Now this is the simplest motor on Earth.

Vengeance [Bound] For Inflicting Suffering Today, the subject for our satsang and samayik is
The root for all kinds of veyr that gets bound [is:], when someone binds veyr with us;
that person has suffered in some way because of us by any means, in any which way then as a result of that [dukh] that person has abhorrence (dwesh) contempt (tiraskar) and ultimately they may even bind veyr. alternatively if someone else causes us to suffer, insults us, causes damage to us
then too we may bind veyr with them.
So in both these ways veyr can be bound by us or that other person may bind it for us from this [veyr] how can we; become free with full awakened awareness, be released from all types of veyr, become free from all the bondages of veyr for that Dada's brilliant science of spiritual knowledge had been revealed There are so many instances, even beyond our imagination, either we or someone else due to us binds veyr.
Especially when someone has suffered because of us, that person especially binds veyr with us.
in Satyug (1st of the four major Eras of Time divided per Eastern philosophy) and in Dwaper (3rd of the four major Eras of Time) and and in Treta (2nd of the four major Eras of Time) the reasons for binding veyr were different and in Kaliyug (4th and current Era of Time), the reasons are different The reasons we have in the historical times for all the veyr bound historically
were [for] the kings - emperors, and the Tirthankars (absolutely Enlightened Ones) for all these kinds [of people] and the Gnanis (knowledgeble persons) history of veyr bound between and amongst these people Right now we neither have a kingdom nor a throne, nor a queen nor are we kings If we had a royal throne then something may happen for that
But right now, instead of kingdoms and thrones, we have other [kinds of] problems if a family were to own 10 vigha (unit of measurement) of land or own one property then amongst themselves they may quarrel over that whereas the people of the past fought for the throne amongst themselves between brothers, between a father and his son, veyr gets bound now in Kaliyug what kind of veyr gets bound observe the different examples veyr bound in Kaliyug Dada says, veyr in Kaliyug is bound with family members the greatest amount [of veyr] is bound in the house with family [with] those people whom we used to sit and dine with whom we would lovingly hug, where we could not do without one another, it is with those very people veyr is bound.
Where there is a lot of raag, A lot of attachment that is where veyr is bound.
[between a] husband and wife. Normally they'll say, "I can't do without him and he can't do without me". So there is raag [in that]
Used a lot of power [he says] Now that you have taken Gnan, She will let go and you too will let go
Then she won't let him get away If the opportunity comes [to take her revenge] in this lifetime she will not let it pass and if it [the opportunity] doesn't come in this life, then ultimately even in the next lifetime, she won't let it go She then may be re-born as your daughter who may then run away with a Muslim boy [against your wish].
And he may give you nothing but trouble. He'll [son-in-law] say "take your daughter back". So then she comes back as a burden for the rest of your life.
It [veyr] will not release you.
It is the very same group [of people] that come together to settle the accounts of veyr in Kaliyug it is not like the kings [of the past] where brothers fought against each other violently using bows and arrows or guns. Now, it is not like that anymore It is like this
In the end, they may come back as a scorpion and sting you and they may come back as a snake and sting you These days you do not find scorpions or snakes in the cities but there are plenty of harmful mosquitoes to be found. If they have bound small amounts of veyr, then they sting you accordingly and go on their way.
so it [veyr] is very risky - very there is a really wonderful way to become free from veyr We should keep forgiving them, keep forgiving them. We are doing pratikraman [of course] but additionally, from my side,
We do not want to carry forward this (burden). We do not wish to bind anything That matter might be over all those interactions are long over, the karmic accounts are over those worldly duties are over that event is also over that matter is also forgotten from our mind, but despite that deep down within us that opinions still remains within.
Escape from this Get released from it. It should not be like this.
So in samayik today take all these close individuals one-by-one Mother father, brothers, sisters, husband-wife, children, mother-in-law - daughter-in-law, extended family members cousins, this one - that one people you deal with in business, with the servants and anyone that you have had conflicts with. From all of this
In this way, you have to see all the incidences in the whole samayik. And for those who have bound veyr with us, If we feel like that then decide that we do not have any claims against them. do their pratikraman.
Because we want to be liberated If we keep holding onto it it will only bother us. It will not let us go.
Do you all understand?
Take each individual closest to you. And especially ones whom this may have happened a lot your intuition will tell you that take this person first [in samayik].
What I want to do in this video is to expose you and introduce you to the idea to what a computer program is.
And just in case you want to follow along I highly recommend you do that because the real way to learn computer science is to really fiddle with things yourself.
This is a Python environment so I'm going to be doing a lot of the programming in Python. And right here, this environment is called PyScripter.
It's free. It's an open-source piece of software.
One of the really interesting developments about this class is this whole customer development process. It says you start with your business model canvas hypotheses, and in fact, what you really do is you blow up the canvas, and you actually post it to the wall, and you use yellow stickies, no pens or pencils allowed, because you are going to get most of them wrong. But you're going to make it visible, and you will actually begin to construct your hypotheses, and the next thing you'll do is look at them and go "Hey, there aren't any facts in this room."
"Let's get out of the building and talk to customers and partners, inventors, and we'll learn how to do this with some rigor, with a process." Not just randomly getting out, but actually design experiments, run tests, get data, and more importantly, get some insight, and the customer development process is kind of interesting. The customer development process is actually a 4-step process.
So, question for you. How many edges are there in an n-node hypercube? Possibly to make it easier for you or possibly to make it harder for you, instead of coming up with an exact answer, I'll just give you a list of the Θ values.
In 2004, my cousin, Nadia, was having trouble with math. She was in New Orleans; I was in Boston. I decided to virtually tutor her.
In 2009, I started doing Khan Academy full time.
In the fall of 2010, we got funding from the Bill and Melinda Gates Foundation, and from Google. And now, we're a real organization. Right now, in a traditional classroom, a teacher has to deliver essentially a "one size fits all" lecture, pretty much guaranteeing that some of the students are going to be lost, or some are bored.
Okay in this example we're going to derive the, input minimized, cost minimizing input levels and the cost function for the Cobb-Douglas case. So remember, the Cobb-Douglas case, whoops, is a production function that looks like this.
Hi, my name is Marcin -- farmer, technologist. I was born in Poland, now in the U.S. I started a group called Open Source Ecology.
Welcome back to CS215. This the beginning of Unit 6, which is going to cover the hardness of network problems. All right, I made another magic trick and I'm going to show it to you now.
Find the place value of 3 in 4,356. Now, whenever I think about place value, and the more you do practice problems on this it'll become a little bit of second nature, but whenever I see a problem like this, I like to expand out what 4,356 really is, so let me rewrite the number.
Now another way to think about this is this is just like saying this is 4 thousands plus-- or you could even think of "and"-- so plus 3 hundreds plus 50, you could think of it as 5 tens plus 6. And instead of 6, we could say plus 6 ones. And so if we go back to the original number 4,356, this is the same thing as 4-- I'll write it down.
I was just looking on the discussion boards on the Khan Academy Facebook page, and Bud Denny put up this problem, asking for it to be solved. And it seems like a problem of general interest.
2 is the same thing as e to the natural log of 2, right?
The natural log of 2 is the power you have to raise e to to get 2. So if you raise e to that power, you're, of course going to get 2. This is actually the definition of really, the natural log.
The antiderivative of e to the au, du, is just 1 over a e to the au. This comes from this definition up here, and of course plus c, and the chain rule. If we take the derivative of this, we take the derivative of the inside, which is just going to be a.
The top k algorithm that we have so far. We talked about using sorting, which runs in time and log n because you sort the whole list and then you can get any top k that you want for any k so it doesn't depend on k. The selection and insertion approach is both run in Θ(nk) essentially because we're repeating for each of the elements that we want to get it out or repeating something like n work.
Formerly the class NP is the set of non-deterministic polynomial time decidable problems-- that is to say that it's a problem that can be dissolved by a program that runs in polynomial time that has non-deterministic elements in it. Now, I'm going to explain what that is in just a moment, but first what I'd like to do is give you a handle on intuitively what this means. I'd like to say the NP stands for nice puzzle problems, so let me explain what I mean by that.
So what's the running time of this going to be? Is it (logn) like the other heap operations we've been looking at? Is it θ(n)?
Be the Avadhuta.
Maybe all your life, you are living with an assumption of who you are, and it's kind of enough. It's not enough but it's enough, because you can make it somehow based upon an identity and live the rest of this bodily existence with that identity. You can do it but you have a choice to go beyond all of this into the truth of your being because all this time you are still only the Being but you are unaware.
When you have contemplated yourself You come to a place, it is only space and peace Go about like that.
Why should you be a facilitator or a teacher? Why should you give your time to Startup Weekend and these entrepreneurs? Number 1, we think you'll learn a tremendous amount yourself just watching a variety of teams start with an idea and watch their process.
At clone market, the customers are possibly known because you copied an existing market like the United States, but the customer needs and why it's a clone is you're going to actually localize all those specific issues for your country or region. There are no competitors if you're first and the risk is misjudging the local news.
A great example is Baidu.
We're going to modify this rank algorithm that we had before to do what I suggested. It's going to return a kind of slightly sorted or less than the one that was given with regard to some value of v. There is a lot of ways to do this some are cleaner and more efficient that others.
Good morning. I've come here to share with you an experiment of how to get rid of one form of human suffering. It really is a story of Dr. Venkataswamy.
(Applause) This helped us build a very ethical and very highly patient-centric organization and systems that support it. But on a practical level, you also have to deliver services efficiently, and, odd as it may seem, the inspiration came from McDonald's.
So they get it in about 20 minutes and those who require surgery, are counseled, and then there are buses waiting, which will transport them to the base hospital. And if it was not for this kind of logistics and support, many people like this would probably never get services, and certainly not when they most need it. They receive surgery the following day, and then they will stay for a day or two, and then they are put back on the buses to be taken back to where they came from, and where their families will be waiting to take them back home.
Code for an example solution is given in the Instructor Comments box below.
Welcome to the Lathe soft jaw video series Presented to you by Haas Automation In our first video
Most often, ID gripping jaws are used to hold parts Which must be completely profiled on the outside face of the part Or where the OD geometry of the part makes the surface difficult to grip
If he were to use regular soft jaws to hold this thin walled part
At higher holding pressures the ring would begin to distort during clamping Pie jaws allow this part to be clamped in a more robust and consistent manner Pie jaws are often used to hold thin wall parts that will deform easily without full support
We set the clamping pressure to 100 psi And we'll keep the spindle speed below the recommended 900 rpm And just as we did when OD gripping
The master jaws at mid-stroke And our program set to cut to the nominal part diameter, these jaws are ready to cut
As recommended in the first video We'll make a narrow groove at the bottom of the jaws So that any work piece with sharp edges will sit flush to the jaw's back face
To demonstrate how uniformly the pie jaws grip the part Andrew mounts an indicator to check how much run out we have, with our part gripped in these jaws At 250 psi clamp pressure, our part's total indicated run out using the pie jaws is five thousandths (0.005", 0.127 mm)
Here is another example of a part that we want to ID grip This pulley has sufficient wall thickness to allow us to use standard soft jaws However, the part's inside diameter bore, which we want to grip is so small
Although there are many factors that you should take into account when choosing regular vs pie jaws These examples represent two possible scenarios to consider when trying to properly support your part Re-cutting your soft jaws
Before disassembly, he finds a mark or feature on the master jaw And scribes a line on the soft jaws to locate them at this exact tooth position in the future Then as he removes each jaw, he numbers it
Several days later... As anyone who's worked in a machine shop knows Tooling sometimes has a habit of disappearing at inopportune moments
Press [HAND JOG], press [CRNT CMNDS] And press [PAGE UP] until you reach the "Position" page With X-axis selected, press [ORlGIN] to zero out the "Operator" position field
The X-axis "Operator" field now shows us the diameter that our jaw faces are set to In our case, we want to re-cut these jaws to the nominal part diameter of 3.950 inches With our jaws checked at a clamped location of 3.935
Adding a taper to your jaws When clamping force increases so does the deformation of the jaws For this reason, when cutting soft jaws it is important to try and use the same holding pressure
Since U0.008 is a diametrical adjustment It will taper each wall four thousandths of an inch (0.004", 0.102 mm) Andrew cuts the taper in the jaws
With the taper cut and the work piece clamped at full pressure
Feeler gauges will probably not fit in the remaining space However, there may still be a small gap Now Andrew uses a slow drying "bluing compound" to check if he needs to make another slight taper cut
We've talked a lot about demand So now let's talk about supply! And we'll use grapes for this example
--so this is price per pound-- In that situation we can produce 1000 lbs in this year. And I've never been a grape farmer, so I actually don't know if that's a reasonable amount or not but I'll just go with it, 1000 lbs.
I'd like to begin with a thought experiment. Imagine that it's 4,000 years into the future. Civilization as we know it has ceased to exist -- no books, no electronic devices, no Facebook or Twitter.
Absolute Humility Today our subject for satsang and samayik is
Dada has said that, "Brother, if you want liberation (moksha) then you will have to come to me." So, we went to him, and said,
It [param vinaya] is a thing for the path of moksha. Dada has put it in another way, A point of view (naya), humility (vinaya), and absolute humility (param vinaya).
That if you do something good for me then I will do something good for you too. If you fight with me then I will fight back with you too. This worldly interaction is called naya
But, it [the humiliation] is suppressed within. it is kept quiet inside... but outside you maintain vinaya [for that person]. And what happens in param vinaya? There is nothing inside, and on top of that, the inner intent of equanimity (samata) exists. not a single subatomic particle (parmanu) is shaken within. one remains in the inner intent of equanimity (samata).
then for a person who is in param vinaya, he will never cause suffering to anyone Then that is considered actual param vinaya.
Others are not suffering because of him Whenever he feels that this person is hurt, he will repent intensely from inside. he will do pratikraman. he will ask for forgiveness that is param vinaya in the real sense.
On the path to moksha when one has these characteristics then there will be param vinaya and through that one will attain moksha that is what Dada has said. Param vinaya...
Even if someone causes us to suffer, from our side, for that person no kind of negative inner intents (bhaav) should arise we look at them positively, we see them only as pure Soul (Shuddhatma). And we settle their file with equanimity (sambhave nikal). Then that, is considered to be in param vinaya.
One experiences oneness (abhedta) Each and Every word of the Gnani touches our heart. In that, the intellect doesn't arise there.
Many a time, many people, when Dada says things their intellect would arise.
[this] may not occur for any ordinary person but even if he is Dada's mahatma then too his intellect may arise. Even here, there are many [mahatmas], when Niruben says things their intellect will arise it happens, doesn't it? when the intellect arises, then understand that a division (bhed) has occurred. one has become separated [from the Gnani]. With what motive,
It will not let talks about the Self settle within you. it is always in an effort to throw everything out Even though you get cash here, it will direct you elsewhere [on another path] "Let me read a book, and see what it has to offer".
So, all these come under breaking vinaya. If some is suffering because of us then Dada says that that is also considered as breaking your vinaya
So, where have you missed being in param vinaya? Towards the Gnani ... towards the Gnani's knowledge ... amongst ourselves, we may have seen faults in others inflicted suffering on others seen the faults of the Gnani Doubted the Gnan
Now close your eyes and we will begin the samayik.
Oh Dada Bhagwan Oh Shri Simandhar Swami prabhu, give me the strength to do a samayik with pure applied awareness of the Self (shuddha upyog), throughout my whole life[faults that have occurred] of breaking param vinaya (absolute humility), [I] may have seen faults in others,
This is where the difference between physical and web/mobile channels first come into play because the MVP for a physical channel that is something you sell directly through stores under the direct sales force is very different than something that you might be building for the web or even more so for a mobile channel. So in a physical channel, what you really want to have is something that customers can touch and feel because you're going to be out talking to them and while you could certainly go out with a PowerPoint deck with a photo of what the product's going to look like, etc., my advice always is invest a day or two in building something even if it's out of Styrofoam and cardboard or if it's something as small as a chip or a microphotograph or a microphotograph of a proposed die layout. That is almost for any physical product you should probably be going out and trying to get some reaction based on something that people could see and touch.
Here's a little bit of Python code. Very simple to do exactly this. Here's our list from the example, and we want to know where 84 will fall.
What I'd like you to do is modify the Python code that we're just looking at to take the list L and the value of V and return a new list L‘ that has the property that V is in its final sorted place, everything to the left of it is to the left of it, and everything to the right of it is to the right of it.
Could the Milky Way be rippling with life and intelligence -worlds calling out to worlds- while we on Earth are alive at the critical moment when we first decide to listen? Our species has discovered a way to communicate through the dark, to transcend immense distances.
"It's too expensive." But, in its fullest modern technological expression, it costs less than one attack helicopter a year.
"We'll never understand what they're saying." But, because the message is transmitted by radio, we and they must have radio physics, radio astronomy, and radio technology in common. The laws of Nature are the same everywhere; so science itself provides a means and language of communication even between very different kinds of beings provided they both have science.
"All through human history advanced civilizations have ruined civilizations just slightly more backward." Certainly. But malevolent aliens, should they exist, will not discover our existence from the fact that we listen.
So to solve this problem we're going to modify partition a little bit. That instead of actually just building a list for us, it actually separates that into three chunks— the ones that are smaller than v, the chunk that is v, and the ones that are bigger than v. All right so given this modification to partition, we can run Top K as follows.

The nature of the natural mind is to go, and to be empty.
Empty of intention. Empty of identification. It offers no tenancy to any concept.
Satsang is for this. To root out fear. To dispel ignorance.
To be free of the molestation of your own judgements and projections. And to see again with the eyes of God. [Silence]
We imagine that we are separate from that pure principle; that is our dream. We are That itself. Perhaps it is not enough that one believes this or even trust.
The being in its human expression in various forms have discovered This. Why not us?
Are we less qualified? We have heard today it said,
'May be I'm not ripe enough'. So even these doubts, we will put under the light of inquiry, to see if they can stand up to the power of Enquiry. The very fact that you are, is enough ripeness.
Remove the one who even believes.
Go even beyond belief, into Pure Being.
CHAPTER I. One morning, as Gregor Samsa was waking up from anxious dreams, he discovered that in bed he had been changed into a monstrous verminous bug. He lay on his armour-hard back and saw, as he lifted his head up a little, his brown, arched abdomen divided up into rigid bow- like sections.
Above the table, on which an unpacked collection of sample cloth goods was spread out--Samsa was a travelling salesman--hung the picture which he had cut out of an illustrated magazine a little while ago and set in a pretty gilt frame. It was a picture of a woman with a fur hat and a fur boa. She sat erect there, lifting up in the direction of the viewer a solid fur muff into which her entire forearm had disappeared.
But that would be extremely embarrassing and suspicious, because during his five years' service Gregor hadn't been sick even once. The boss would certainly come with the doctor from the health insurance company and would reproach his parents for their lazy son and cut short all objections with the insurance doctor's comments; for him everyone was completely healthy but really lazy about work. And besides, would the doctor in this case be totally wrong?
"I'm coming right away," said Gregor slowly and deliberately and didn't move, so as not to lose one word of the conversation. "My dear lady, I cannot explain it to myself in any other way," said the manager;
"I hope it is nothing serious. On the other hand, I must also say that we business people, luckily or unluckily, however one looks at it, very often simply have to overcome a slight indisposition for business reasons." "So can Mr. Manager come in to see you now?" asked his father impatiently and knocked once again on the door.
"But Mr. Manager," called Gregor, beside himself and, in his agitation, forgetting everything else, "I'm opening the door immediately, this very moment. A slight indisposition, a dizzy spell, has prevented me from getting up. I'm still lying in bed right now.
"For God's sake," cried the mother already in tears, "perhaps he's very ill and we're upsetting him.
Grete!
Grete!" she yelled at that point. "Mother?" called the sister from the other side. They were making themselves understood through Gregor's room.
"fetch a locksmith right away!" The two young women were already running through the hall with swishing skirts--how had his sister dressed herself so quickly?- -and yanked open the doors of the apartment. One couldn't hear the doors closing at all.
One of interesting things about market type is that it really gives us a handle in trying to understand the expected time of profitability from shortest to longest. Take a look at the list below and rank the markets in order of expected time to profitability.
And you said just a little while ago: "That will bite you." That comes to bite, but I don't understand:
No. No. The Noise of Identification
Why would I want to continue believing in a ghost story.... which brings in a noise, which is also un-necessary noise? I.... I don't want to, and yet it happens.
By this I mean that you keep forgetting and running towards this thing. At some point, it must be... May be for few times after there is some... may be a kind of habit.
Let's fast forward: Five weeks later...
"oh man, don't do that!" Will you be doing this? Once you have seen something is not true, will you keep on being fazed by it? Something will change.
Look clearly at that which affronts your being. Like staring at an aggressive monkey let it look away first otherwise... you lose.
Look clearly and penetratively at that which your mind fears to see until it fades in the neutrality of your seeing.
All right. Let's figure out what the answer is. Now, there's a couple of things that I want to try to illustrate with this example.
I touched on this a little bit in the video on how variation can be introduced into a population, but I think it's fairly common knowledge that all of us-- when I talk about us I'm talking about human beings, and frankly, most eukaryotic organisms-- we're the product of sexual reproduction. So if this is the first cell that had the potential to become Sal, we know that this first cell-- let me say this is the nucleus of that first cell so I can draw the whole cell and all that, but let's just focus on the nucleus. It has 23 chromosomes.
I'll just draw the whole egg like that. I'll just focus on the DNA from now, so my mother's DNA, it had 23 chromosomes. So it didn't have pairs, and this is key.
So that's a gamete and this is a gamete.
Both a sperm cell or an egg cell, they're both examples of gametes. Now, the whole reason why I'm doing this is I want to introduce you-- and I already introduced this notion to you when we talked about the variation of population, that, look, this has my full chromosome complement.
And I remember that because di- often is a prefix associated with having two of something, and so you have twice the number of chromosomes. So this is haploid, this is diploid number, and this is for humans, right? For an organism where the diploid number is N, and you'll sometimes see this notation, so I want to make sure you're comfortable with it, there's some organism, or actually any organism.
There were 200 million, roughly. There could've been 200 to 300 million other sperms in that race.
From the moment we're born, we're already the product of an intense competition amongst these male-- I guess we could call them male gametes, or amongst these sperm cells. Some of them might have had weird mutations, that they didn't know which direction to swim, they happened to go in the wrong direction, maybe some of them had weird tails that didn't allow them to swim as fast, so you're already on some level selecting for fitness within this environment. So if you had some weird mutations from the get go in some of these sperm cells, it would have been less likely, especially if they affected their ability to kind of swim, it would've been less likely that they would have been the ones to win this race.
Now, we're talking about gazillions of cells. You have your human being, and I'll just draw a very simple diagram, outline of a human being.
When I was in high school, I was a class artist, so I don't want to make this representative of my true artistic ability. I'm doing this here just to kind of give you an idea. But anyway, eventually, you keep dividing these cells and you end up with a human being, and this human being, you know, you wouldn't even notice the cells on this scale.
And meiosis is essentially what a germ cell undergoes to produce gametes. And so if this germ cell undergoes meiosis, and I'll do a whole video on the mechanics of it, instead of two cells, it'll actually produce four cells that each have half the number of chromosomes in them, so these cells are haploid. In the case of a male, these would be sperm cells.
DNA because of crossovers, and we saw that in the variation video, then that will introduce new forms or new variants inside that could be passed on to your children. And I really want to make that point there, because we talk about mutations, but there's different types of mutations. There's some mutations that won't be passed on to your children, and those are the ones that occur in your somatic cells.
Bu konuya varyasyonların bir populasyonu nasıl etkilediğini anlattığım videoda değinmiştim ama bence hepimiz -bizden kastım bütün insanoğlu ve birçok ökaryot organizma- biz eşeyli üremenin ürünüyüz.
Şimdi, bu hücrenin Sal olabilme potensiyeli var dersek
The focused awareness of the knower vis-à-vis the object or thing to be known, when various subtle phases arise in the internal functioning mechanism in every human being composed of the mind, the intellect, the chit and the ego. Let's talk a little bit about the samayik
"Why is the bridge so high?"
[We casually have an opinion] "this man does not have any hair on his head"; " he looks so young and his hair is gone." "and his is gray [hair]?" But why are you so concerned?
Then you see that the gutters are overflowing and [say] these people are not cleaning it. It is so dirty! Why are you so [worried]
Oh Dada Bhagwan Oh Shri Simandhar Swami Prabhu Give me the strength to do a samayik with pure applied awareness of the Self (shudha upayog)
In every incident of this life, whatever circumstances we pass through, whatever conditions that we have to go through, at that time, in the antahkaran towards the conditions, or circumstances, or people, the various different phases that arise.
May I see all of them In the form of gneya (objects or things to be known) and may I be able to remain in the state of gnata (knower). Give me the power and energy to do such a samayik.
Give me the absolute energy to do such a samayik
If file 1 has seen anyone's faults, or engaged in even the most ordinary inner intents of atikraman, then at that very moment, may I get [File 1] to do pratikraman, and may I be able to keep undivided shuddha upayog. For that give me absolute energies. [I surrender] my mind-speech-body all the illusory attachments associated with my name
I was speaking to a group of about 300 kids, ages six to eight, at a children's museum, and I brought with me a bag full of legs, similar to the kinds of things you see up here, and had them laid out on a table for the kids. And, from my experience, you know, kids are naturally curious about what they don't know, or don't understand, or is foreign to them. They only learn to be frightened of those differences when an adult influences them to behave that way, and maybe censors that natural curiosity, or you know, reins in the question-asking in the hopes of them being polite little kids.
"Hey, why wouldn't you want to fly too?" And the whole room, including me, was like, "Yeah."
(Laughter) And just like that, I went from being a woman that these kids would have been trained to see as "disabled" to somebody that had potential that their bodies didn't have yet. Somebody that might even be super-abled.
(Laughter) I thought, "Well, that's amazing, because I don't feel disabled." And it really opened my eyes to this conversation that could be explored, about beauty.
(Laughter) So this magazine, through the hands of graphic designer Peter Saville, went to fashion designer Alexander McQueen, and photographer Nick Knight, who were also interested in exploring that conversation. So, three months after TED I found myself on a plane to London, doing my first fashion shoot, which resulted in this cover --
14 hours of prosthetic make-up to get into a creature that had articulated paws, claws and a tail that whipped around, like a gecko.
(Laughter) And then another pair of legs we collaborated on were these -- look like jellyfish legs, also polyurethane.
(Laughter) Today, I'm 6'1". And I had these legs made a little over a year ago at Dorset Orthopedic in England and when I brought them home to Manhattan, my first night out on the town, I went to a very fancy party.
(Laughter) (Applause) And the incredible thing was she really meant it. It's not fair that you can change your height, as you want it.
(Applause)
So it's 1995, I'm in college, and a friend and I go on a road trip from Providence, Rhode Island to Portland, Oregon. And you know, we're young and unemployed, so we do the whole thing on back roads through state parks and national forests -- basically the longest route we can possibly take.
My friend looks at me totally blankly. There's actually a gentleman in the front row who's doing a perfect imitation of her look. (Laughter)
So why do we get stuck in this feeling of being right? One reason, actually, has to do with a feeling of being wrong. So let me ask you guys something -- or actually, let me ask you guys something, because you're right here:
(Laughter) So this is one reason, a structural reason, why we get stuck inside this feeling of rightness. I call this error blindness.
1,200 years before Descartes said his famous thing about "I think therefore I am," this guy, St. Augustine, sat down and wrote "Fallor ergo sum" --
"I err therefore I am." Augustine understood that our capacity to screw up, it's not some kind of embarrassing defect in the human system, something we can eradicate or overcome. It's totally fundamental to who we are.
I found myself listening to a lot of episodes of the Public Radio show This American Life. And so I'm listening and I'm listening, and at some point, I start feeling like all the stories are about being wrong.
"I've lost it. I've become the crazy wrongness lady. I just imagined it everywhere," which has happened.
No offense, but this entire conference is an unbelievable monument to our capacity to get stuff wrong. We just spent an entire week talking about innovations and advancements and improvements, but you know why we need all of those innovations and advancements and improvements? Because half the stuff that's the most mind-boggling and world-altering --
TED 1998 -- eh.
(Laughter) Didn't really work out that way, did it?
(Laughter) Where's my jet pack, Chris?
(Laughter) (Applause) So here we are again. And that's how it goes.
"Wow, I don't know. Maybe I'm wrong." Thank you.
I thought I would do another example of partial quotient method for long division
For this quiz, let's consider an example where we're selling business intelligence software into an enterprise customer, a large business. Why don't you match the titles below with the roles of the customers?
Ron and Hermione are practising lifting feathers into the air with magic. Hermione can lift a feather 35 feet into the air which is 5 times as high Ron can lift a feather. How high can Ron lift a feather with his magic?
So what's 35 divided by 5? Well, 5 times 7 is 35. So 35 divided by 5 is 7.

The modern corporation as we know it was first formed in 1602 with the government chartered Dutch East India Company. This is kind of the first modern corporation with shareholders and organizations that kind of if you squinted looked like something closed to modern companies today.
By the 1850s in the United States with railroads spanning the entire country, corporations needed more sophisticated organizations and the fact the first org chart was drawn in 1856 to just manage corporations and by the beginning of the 20th century, educators started realizing that there was a need for an educated management class to administer and execute these corporations because at least in the United States we were going from local economies to regional economies to a national economy, yet we did not have a trained management class and so in a brilliant insight, Harvard set up the first masters of business administration course called the MBA and the first graduating class in 1910 was the first of a cadre of business administrators that made the 20th century the modern corporate century. The MBA curriculum is designed to provide managers and administrators with the tools they needed to run existing and growing companies. Accounting, strategy, operations, leadership, organizational behavior, human resources management and these stack of tools were just incredibly important for the growth of large companies but what's really interesting what that missed is that they were really no tools provided in this curriculum for starting new businesses.
I'm hoping if you've been paying attention that that was pretty easy to see that that's linear. It's just running through each of the elements in the list and doing constant work for each of those elements so the total of line time is going to be Θ(n).
I want to add one super fast addendum to the video on Friedel-Crafts acylation.
In the last step of the mechanism, I had this chlorine swipe the electron, or essentially that electron that was with the aluminum. It was given to the hydrogen proton.
I didn't want to forget that in that last step of the Friedel-Crafts acylation. We also get some hydrogen chloride.
If you know how the world financial system works you know the game that you're playing and if you don't know the game and the rules that we're playing by you are going to get slaughtered, you are going to get slaughtered. Ever since the Federal Reserve was born, we have been living under a lie. In order for us to mantain the levels we've got and to maintain the prosperity
Guide to Investing in Gold and Silver, is part of the Rich Dad series that Robert Kiyosaki started, the original book. Robert Kiyosaki says: write a book no other instructions: write a book, and so I start writing this book two and a half years of research and writing probably 30 hours a week, every week for two and a half years. It's a very well researched book.
"it went down so many points". Anyway, that's the Dow measured in points, but if you go every month during this entire graph from the year 1900 to today, and each day you take the points on the Dow and divide it by the price of gold you get how many ounces of gold one share of the Dow is worth, and this is what it looks like measured in gold. It's not going anywhere, it's got a mean of about 4 ounces of gold, which means that the price of gold should be one quarter of the points of the Dow and then things will sort of be in equilibrium.
"Banks create money by 'monetizing' the private debts of businesses and individuals". Federal Reserve Bank of New York. So, now the miracle of fractional reserve lending comes in to play.
I start referring to it as the numbers supply. the M3 number supply, uh... the base number supply because they're just numbers that somebody made up. I can write numbers on a post-it and hand them out like this. They make them up, they type them in a computer, it is nothing but a supply of numbers, How many numbers are there?
M1 is uh... cash in circulation uh... plus checking, checking accounts uh...
M3 was the broadest measure that incorporated the most different types of of bank deposits and so on, not at all the entire currency supply, the entire currency supply is actually total credit so about 53 trillion today and it's uh... stalled and started to shrink. But M3, they used to publish it every month it was the uh... measurement of the currency supply that most newsletter writers and uh... on the news that they would report and the Fed hid it from us in March of 2006 claiming that it was too expensive to compile all this information and that it was useless anyway that you couldn't glean anything from M3 that you couldn't get from M2. Now, here's the real kicker.
I'm 99.4 percent sure that this information is correct, and what you see here is that there's a little collapse going on of the currency supply up here, and it's not huge we've gone from you know this would be 15 so about 14.7 trillion dollars down to just under 14 trillion dollars in M3, but base currency is a component of the M3 that red part on the bottom is part of it, and they've been pushing that up like crazy
Why? Because there's a credit collapse going on right now. When you deduct the base money from the credit based portion of this part of M3, so the portion of what we borrow into existence what happens is that it shows this enormous collapse going on.
There's the Nasdaq, so that's uh... uh... what a dead cat bounce looks like. The initial crash on the Nasdaq was 38 percent. The total crash was 78 percent.
The SP 500, these are PE ratios, how many here knows know what a PE ratio is?
OK, how many do not? It's OK, raise your hand and say that you don't. OK, it's the price of a share of stock divided by the earnings of the company.
The S&P only goes back to the year 1950 but professor Robert Shiller of Yale University uh... reconstructed the S&P and took the 500 largest companies in America and took it all the way back to the year 1880. So you have a hundred and twenty years or two hundred and twenty one years of data here.
PE is at almost 45, absolutely insane investing in a stock and having to wait 45 years to be in profit. This was nuts and people were chasing stocks like crazy. This is the tech boom and so on.
The S&P, the Dow they're way, way overvalued in a bubble, we're having a deflationary collapse of the currency supply, the markets have to go down, when they do, the rest of the world's, where the United States goes so goes the rest of the world. These markets all have to collapse. Now, we have some real estate bubbles going on.
"we gotta do something about it!" It doesn't feel good to be in a recession so they try and pump everything up but they don't realize that they're just making everything worse later. Everything they do is gonna come back to haunt them as more uh... inflation eventually uh... or this deflation I'm talking about is the expansion of credit contracting.
Also the development of the investor mindset. before the Arisa Act and before Nixon took us off of gold, before 1971 when Nixon took us off of gold if you went to work between your late teens or mid twenties, depending on whether you went to college or not, you could expect that if you saved ten percent of your income every month then when we got into your sixties you can retire and live off the interest in your savings account. Can you do that today? Nobody can live off the interest of its savings account, unless he got twenty million bucks sitting there, fifty million bucks, that's the only way you're going to get by. and you wouldn't leave in the savings account because you're losing to inflation, your principle is getting whittled away because of inflation. uh...
OK? uh...
When you type on the keyboard you're typing on silver, when you look at a DVD or a CD you're looking at silver, when you look in the mirror, you're looking at silver. When you look through a thermal pane window, you're looking through silver. It's everywhere, it's a biocide, it's going into superconductors, it's going into RFlD chips, but you know what?
I was standing in front of a green screen just sort of drawing this charts out of memory and our animator Adam had to sort of flow the charts in front of me and move them around to match them up with my finger, but uh... uh... that is what you get as a customer, it's on the Youtube channel "Why Gold And Silver?" so if you do a search for "sell silver Mike Maloney", because it's when to sell your gold and silver so "sell silver Mike Maloney" you'll get that video in its entirety, and there are dozens of videos on
"WhyGoldAndSilver"
"GoldMikeMaloney" and "WealthCycles". So those are the 3 Youtube channels that you can go to, and each one of them has a few dozen videos on it. uh... This is the gold panic in 1948 in Shanghai, if you wait until the last minute,
It's the amount of energy you can extract from it, the amount of the BTUs, from combustion, when you burn it, and you saw that during the Weimar hyperinflation, people used the currency as fuel to heat the house. Currencies have been backed by oil, by gold and silver by land, but as soon as you remove some things that you can't, some things that put financial constraint, where you just can't print as much currency as you want, the currency is pretty much doomed. It's beyond astonishing...
Existing markets--well, the customers--well, they're know. We know who they are. They exist.
"What do they really care about for gains and pains." They could tell us. Competitors, by definition, they are many. The risk--well the risk is lack of branding, lack of sales, lack of distribution, and well unfortunately, sometimes your product really does not live up to the claims.

We're told that Imran is two years older than Diya.
Diya is 2.
How old is Imran?
So I encourage you to pause this video and try to think about this yourself.
How old is Imran given the information here? So let's use some letters to represent Imran and Diya's age. Let's say that I is equal to Imran's age.
A heap is a kind of data structure, a bunch of values that actually is a bunch of values arranged in a kind of a graph specifically it's a balanced binary tree and each of the nodes has a value in it and for the heap property to be satisfied the value in the node in every node in the tree has to be no bigger than the values in the children. Let me show you an example. Here's a balanced binary tree with 20 nodes.
We are on problem 63. The height of a triangle is 4 inches greater than twice its base. Let me this triangle in question.
Let's say this is the base. Let's call that b. So then the height, that's that, is 4 inches greater than twice its base.
So area is equal to 1/2 base times height. Well they told us that the height is four more than twice the base, so we can just substitute that in. And then we'll have a just in terms of the base.
Does 12 go into it? Yeah, 12 goes into 168, and I think it goes into it 14 times. So that works.
Again, a little further definition in existing market incumbents exists. Customers can name the market. Customers want or need better performance.
Typically, incumbents unless they're large corporations that are falling asleep will defend their turf and remember the network effects of an incumbent. It might mean that it's not only about their product but it might be all the ancillary services and third-party offerings they have in their catalog. And remember, just as you're focused on innovation, most incumbents are focused on innovation.
I was only four years old when I saw my mother load a washing machine for the very first time in her life. That was a great day for my mother. My mother and father had been saving money for years to be able to buy that machine, and the first day it was going to be used, even Grandma was invited to see the machine.
"How many of you doesn't use a car?" And some of them proudly raise their hand and say, "I don't use a car." And then I put the really tough question:
"Wopp!" they will say. And they will start to use as much as the Old West are doing already. And these people, they want the washing machine.

So as we said, understanding these 3 components of value proposition work together with understanding the 3 components of customer segments. And in value proposition, the goal of this is to find out that minimum viable product. And in customer segments, the goal is to understand in detail the customer archetype or persona.
Lets take a look at the solution to this its a little bit tricky. Firstly, at the top of our file we declare two new variables, frameRate and frame. Now, frameRate represents how often we'd like to actually call the animate function.
Abe went running 4 days this past week, he ran 9 kilometers on each day In that same week Beth ran 15 fewer kilometers than Abe, how many kilometers did Beth run that week? So I encourage you to pause this video and to try this on your own.
So what is this? What is 4 times 9 km? Well, this is essentially 9 + 9 + 9 + 9, so we could just add up the 9's.. 9 plus 9 is 18, plus 9 is 27, plus 9 is 36..
Now that we have a loaded image, we need to draw that image to the canvas via the canvas.drawlmage APl. This function takes the image object itself as well as the locations on the canvas that we'd like to draw that image. As you can see, there are some other parameters that drawlmage takes.

The whole point of building up all this heap based technology is to allow us to do two things efficiently. One is getting and removing the min and the other one is inserting new elements into the heap. We like both of these to run in log n time, and if they are, then we can use them in the top k scenario that I was describing before.
Until about 2006, if you talk to anyone, especially real estate agents, they'd always tell you that on average, nationwide, that housing always goes up in price. There could be layoffs. And maybe oil drops off and people have layoffs in Texas, so housing prices go down in Texas.
So they are four critical resources you need to think about as we just we talk about their physical resources, final resources, human resources, and intellectual resources. Let's take a look at each one. For physical resources, this might seem at first kind of the obvious is your company facilities and that is office base, company location are you in downtown ??? or are you in Ann Arbor Michigan or you were in Delft in the Netherlands or ???.
When I knew I was going to come to speak to you, I thought,
"I gotta call my mother." I have a little Cuban mother -- she's about that big. Four feet.
(Laughter) I called her up.
"Hello, how're you doing, baby?" "Hey, ma, I got to talk to you." "You're talking to me already.
"Ma, don't start!"
And I told her I was coming to TED, and she said,
"What's the problem?" And I said, "Well, I'm not sure." I said, "I have to talk to them about stories.
(Laughter) I said, "You're a peach, ma. Pop there?"
(Laughter) Then my pop got on there. My pop, he's one of the old souls, you know -- old Cuban man from Camaguey.
He was born there in 1924. He grew up in a bohio of dirt floors, and the structure was the kind used by the Tainos, our old Arawak ancestors. My father is at once quick-witted, wickedly funny, and then poignancy turns on a dime and leaves you breathless.
(Laughter)
"After what I just told you?" My whole life, my father's been there. So we talked for a few minutes, and he said,
"Why don't you tell them what you believe?" I love that, but we don't have the time. Good storytelling is crafting a story that someone wants to listen to.
(Spanish)
"You don't speak English?" "No."
(Laughter) But eventually, every dog has its day, and she ended up in traffic court, where she bartered with the judge for a discount. There's a historical marker.
(Laughter) This is her ensemble. And this is the woman that wants me to come on a Saturday morning when I have a lot to do, but it doesn't take long because Cuban guilt is a weighty thing.
(Laughter) I said, "Is that thing real?" "I think so."
"The man" -- I have to tell you as she did, because it loses something if I don't, you know --
"he come to the window, and he does a thing like this, which tells me he's pretty old, you know.
So I look up and I'm thinking, maybe he's still going to think I'm kind of cute." "Ma, are you still doing that?" "If it works, it works, baby.
Well, wouldn't you know, he had been in Honduras for the Peace Corps."
(Laughter) So he's talking to her, and at some point she says,
"Then, you know, it was it. That was it. It was done."
(Laughter) You should be terrified. Now, I don't know if she's toying with me, kind of like a cat batting back a mouse, batting back a mouse --
"Why do we have to take pop's underwear back now? And why? What is wrong with his underwear?"
(Laughter) Olivia? Huh?
"Look, the Chevy." You want to laugh, but you don't know -- you're that politically corrected, have you noticed? Correct the other direction now, it's OK.
(Laughter) And years of therapy later, we're doing great. We're doing great.
(Spanish) And she's still talking while she puts the car in park, hits the emergency brake, opens the door, and with a spryness astounding in a woman her age, she jumps out of the car, knocks out the phone books, and then she walks around -- she's carrying her cheap Kmart purse with her -- around the front of the car. She has amazing land speed for a woman her age, too.
"How do you spell that? What year? OK."
"No, mama, you got to look." I got to look. You got to look.
"Back it up, buddy! No, it's reserved!"
(Laughter) Ready? Brace yourselves.
(Laughter) And she's bringing me in with a slight salsa movement. She is, after all, Cuban.
(Laughter)
"Ma, have you no shame? People are watching us all around," right? Now, some of them you've got to make up, people.
"have you no shame?"
"No. I gave it up with pantyhose -- they're both too binding."
(Laughter) (Applause) Yeah, you can clap, but then you're about 30 seconds from the end. I'm about to snap like a brittle twig, when suddenly someone taps me on the shoulder.
(Laughter) I turn around, but it's not a child. It's a young woman, a little taller than I, pale green, amused eyes.
"is that your mother?" I said, "No, I follow little old women around parking lots to see if they'll stop. Yes, it's my mother!"
"No, no, honey, we just want to know one more thing." I said, "Look, please, let me take care of her, OK, because I know her, and believe me, she's like a small atomic weapon, you know, you just want to handle her really gingerly." And the girl goes, "I know, but, I mean, I swear to God, she reminds us of our mother."
"You know what, honey?" "What, ma?" "I'm going to drive you crazy probably for about 14, 15 more years, if you're lucky, but after that, honey, you're going to miss me."
(Applause)
I wanna talk a little bit more about reflection and specular and diffuse reflection in particular and to start of, I wanna make a minor correction to the last video, and it's actually a pretty interesting correction because in this image right here I talked about a double reflection
It never hurts to get a lot of practice. So, in this video I'm just going to do a bunch more of essentially what we call long division problems. And so if you have four divided into two thousand two hundred ninety-two.
Four goes into twenty-two how many times? Let's see.
Four times five is equal to twenty.
Four times six is equal to twenty-four. So six is too much. So four goes into twenty-two five times.
Five times four is twenty. There's going to be a little bit of a leftover, And then we subtract.
Four goes into twenty-nine how many times? It goes into it at least six times.
What's four times seven? Four times seven is twenty-eight. So it goes into it at least seven times.
What's four times eight?
Four times eight is thirty-two, so it can't go into it eight times. So it's going to go into it seven.
Four goes into twenty-nine seven times.
Seven times four is twenty-eight. Twenty-nine minus twenty-eight, to get our remainder for this step in the problem, is one. And now we're going to bring down this two.
Four goes into twelve? That's easy.
Four times three is twelve. Four goes into twelve three times.
Three times four is twelve. Twelve minus twelve is zero. We have no remainder.
Seven goes into sixty-four how many times? Let's see.
Seven times seven is? Well, that's way too small. Let me think about it a little bit.
Seven times ten is seventy. So that's too big. So seven goes into sixty-four nine times.
Nine times seven is sixty-three.
Sixty-four minus sixty-three, to get our remainder at this stage, is one. Bring down the seven.
Seven goes into seventeen how many times? Well, seven times two is fourteen. And then seven times three is twenty-one.
Two times seven is fourteen.
Seventeen minus fourteen is three. And now we bring down the five.
And seven goes into thirty-five-- That's in our seven multiplication tables-- five times.
Five times seven is thirty-five. And there you go. So the remainder is zero.
So, three goes into-- And actually, I'm not sure if this will have a remainder. In the future video I'll show you how to figure out whether something is divisible by three.
One plus seven is eight.
Eight plus three is eleven.
Eleven plus five is sixteen.
Sixteen plus nine is twenty-five. Twenty-five plus two is twenty-seven. So actually, this number is divisible by three.
Three goes into one zero times. So we can just move forward. You could write a zero here, and multiply that out.
Three goes into seventeen how many times? Well, three times five is equal to fifteen. And three times six is equal to eighteen and that's too big.
Five times three is fifteen. And we subtract. Seventeen minus fifteen is two.
Three goes into twenty-three how many times?
Well, three times seven is equal to twenty-one. And three times eight is too big. That's equal to twenty-four.
Seven times three is twenty-one. Then we subtract.
Twenty-three minus twenty-one is two. Now we bring down the next number. We bring down the five.
Three goes into twenty-five how many times?
Well three times eight gets you pretty close and three times nine is too big. So it goes into it eight times.
Eight times three is twenty-four. I'm going to run out of space. You subtract, you get one.
Twenty-five minus twenty-four is one. Now we can bring down this zero. You bring down this zero, just like that.
Three times three is nine. That's about as close to ten as we can get.
Three times three is nine. Ten minus nine-- I'm going to have to scroll up and down here a little bit--
Three goes into nineteen how many times?
Well, six is about as close as we can get. That gets us to eighteen. So three times six.
Six times three-- let me scroll down.
Six times three is eighteen.
Nineteen minus eighteen-- we subtract it up here too.
Nineteen minus eighteen is one and then we're almost done. I can revert back to the pink. We bring down this one right there.
Three goes into eleven how many times? Well, that's three times because three times four is too big.
Three times four is twelve, so that's too big. So it goes into it three times. So three goes into eleven three times.
Three times three is nine. And then we subtract and we get a two. And there's nothing left to bring down.
Today, we are going to talk about revenue models. Very simply is, how does your company make money. So in our last lectures we talked about value proposition, customer segments, distribution channels, customer relationships; get, keeping and growing customers.
Let's continue on with our study of rotation of functions around the x, and we'll soon see the y-axis as well. So let's do a slightly harder example than what we've been doing, but I think it might be obvious how to approach it. So there's my y-axis, there's my x-axis, and in a couple of--
Because square root of 1 is 1, and 1 squared is 1, so that would look something like this.
They should be actually symetric around y equals x, but anyway. So say y equals x squared looks like that. So my question now is, what is the volume if I were to take this figure and rotate it around?
It'll be the volume formed when that is rotated around, and then the whole solid volume minus the volume when minus this volume. So if we took the y equals x squared, y equals x squared would look something like that, and then if you rotated it around the axis, it would look something like that. I don't know if you've ever been to Morocco, but they have these tajin plates that the tops look a lot like that.
This time, we're going to say the volume of the revolution of y equals square root of x minus the volume of the revolution of y equals x squared. So let's do the problem. So the total volume-- let me do a good color, that looks good-- total volume is going to be equal to the volume formed when we rotate y equals square root of x around the x-axis.
That's pi times 2, get a common denominator of 10, 5/2 is 1/2 minus 2/10 is 1/5, so this equals, this would be 3, so we get 3pi over 10. That's the volume formed. So it's almost easier to figure out the volume of this figure than to draw it.
Why did the United States attack Lybia, Iraq, Afganisthan and Yemen?
Why are U.S. operatives helping to destabilize Syria?
And why is the United States goverment so intent in taking down Iran?
In spite of the fact that Iran has not attacked any country since 1798.
And what's next?
What are we headed for?
When you look at the current trajectory that we're on it doesn't make any sense at all if you evaluate it based on what we're taught in school.
And it doesn't make any sense if you base your worldview on the propaganda the mainstream media tries to pass off as news.
But it makes perfect sense once you know the real motives of the powers that be.
In order to understand those motives we first have to take a look at history.
In 1945 Bretton Wood's agreement established the dollar as the world reserve currency which meant that international commodities were priced in dollars.
The agreement which gave the United States a distinct financial advantage was made in the condition that those dollars were to remain redeemable for gold at a consistent rate of 35 dollars per ounce.
The United States promised not to print very much money, but this was on the honor system, because the Federal Reserve refused to allow any audits or supervision of it's printing presses.
In the years leading up to 1970, expenditures in the Vietnam war made it clear to many countries that the U.S. was printing far more money that it had in gold. And in response they begin to ask for their gold back.
This of course set of a rapid decline in the value of the dollar.
The situation climaxed in 1971 when France attempted to withdraw it's gold, and Nixon refused.
On August 15th he made the following announcement:
I have directed the Secretary of the Treasury to take the action necessary to defend the dollar against the speculators.
I have directed Secretary Connally to suspend temporarily the convertibility of the dollar into gold, or other reserve assets, except in amounts and conditions determined to be in the interest of monetary stability and in the best interest of the United States.
This is obviously not a temporary suspension as he claimed, but rather a permanent default.
And for the rest of the world to entrust the United States with their gold, it was outright theft.
In 1973, President Nixon asked King Fayçal of Saudi Arabia to accept only U.S. dollars as payment for oil and to invest any excess profits in U.S. treasury bonds, notes and bills.
In return, Nixon offered military protection to Saudi oil fields.
The same offer was extended to each of the world's key oil producing countries.
And by 1975, every member of OPEC had agreed to only sell their oil in US dollars.
The act of moving the dollar off of gold and tying it to foreign oil instantly forced every oil importing country in the world to start maintaining a constant supply of federal reserve paper.
And in order to get that paper, they would have to send the real physical goods to America.
This was the birth of the Petrodollar.
Paper went out, everything America needed came in and the United States got very, very rich as a result.
It was the largest financial con in recorded history.
The arms race of the cold war was a game of poker.
Military expenditures were the chips and the U.S. had an endless supply of chips.
With the petrodollar under it's belt it was able to raise the stakes higher and higher outspending every other country on the planet until eventually U.S. military expenditures surpassed that of all other nations in the world combined. Soviet Union never had a chance.
The collapse of the communist block in 1991 removed the last counter balance to American military might.
The United States was now an undisputed superpower with no rival.
Many hoped that this would mark the beggining of a new era of peace and stability.
Unfortunately, there were those in high places who had other ideas.
Within that same year, the U.S. invaded Iraq in the first gulf war.
And after crushing the Iraqi military and destroying their infrastructure, including water purification plants, hospitals, crippling sanctions were imposed which prevented that infrastructure from being rebuilt.
These sanctions which were initiated by Bush senior were sustained by the entire Clinton administration,
lasted for over a decade and were estimated to have killed over five hundred thousand children the Clinton administration was fully aware of these figures.
LESLEY STAHL:
And you know, is the price worth it?"
MADELElNE ALBRlGHT:
"I think it is a very hard choice.
The price, we think the price is worth it."
Miss Albright, what exactly was it that was worth killing five hundred thousand kids for?
In November of 2000, Iraq began selling it's oil exclusively in Euros this was a direct attack on the Dollar and on U.S. financial dominance and it wasn't going to be tolerated.
In response U.S. government with the assistance of the mainstream media began to build a mass propaganda campaign claiming that Iraq had weapons of mass destruction and was planning to use them.
In 2003, the U.S. invaded and once they had control of the country oil sales were immediately switched back to Dollars.
This is particularly notable due to the fact that switching back to the Dollar meant a 15 to 20% loss in revenue due to the Euro's higher value.
It doesn't make any sense at all, unless you take the petrodollar into account.
GEN.
WESLEY CLARK:
"So I came to see him a few weeks later and by that time we were bombing in Afganisthan
I said are we still going to war with Iraq?
He said oh, it's worse than that.
He reached over on his desk and said and picked up a piece of paper he said I just got this down from upstairs meaning the Secretary of Defense office today and he said this is a memo that describes how we're gonna take out 7 countries in 5 years starting with Iraq and then Syria, Lebanon, Lybia, Somalia, Sudan and finish it off with Iran.
Let's take a look at the events of the past decade and see if you see a pattern.
In Lybia, Gaddafi was in a process of organizing a block of African countries to create a gold based currency called the Dinar which he intended to use to replace the Dollar in that region.
U.S. and NATO forces helped destabilize and topple the Lybian government in 2011 and after taking control of the region US armed rebels executed Gadafi in cold blood and immediately set up a Lybian central bank.
Iran has been actively campaigning to pull oil sales off from the Dollar for some time now.
And it recently secured agreements to begin trading it's oil in exchange for gold.
In response the US government with mainstream media assitance has been attempting to built up international support for military strikes on the pretext from preventing Iran from building a nuclear weapon.
In the mean time they established sanctions which US officials openly admit are aimed at causing a collapse at the Iranian economy.
Syria is Iran's closest ally and they are bound by mutual defense agreements.
Countries currently in the process of being destabilized with covert assitance from NATO and though Russia and China have warned the United States not to get involved, the White House has made statements within the past month indicating they are considering military intervention.
It should be clear that military intervention in Syria and Iran isn't being considered, it's a full gone conclusion.
Just as it was in Iraq and Lybia, the US is actively working to create a context which gives the the diplomatic cover to do what they have already have planned.
The motive for these invasions and covert actions becomes clear when we look at them in the full context and connect the dots those who control the United States understand that even if a few countries begin to sell their oil in another currency it'll set off a chain reaction and the Dollar will collapse.
They understand that there is absolutely nothing else holding the value of the dollar at this point and so does the rest of the world. but rather than accepting the fact that the dollar is near the end of it's life span the powers that be have made a calculated gambit.
They have decided to use the brute force of the military to crush each and every resistance state in the Middle East and Africa.
That in itself would be bad enough, but what you need to understand is that this is not gonna end with Iran.
China and Russia have stated publically and on no uncertain terms that they will not tolerate an attack on Iran or Syria.
Iran is one of their key allies, one of the last independent oil producers in the region.
And they understand that if Iran falls, then they'll have no way to escape the Dollar without going to war and yet the United States is pushing forward in spite of the warnings.
What we are witnessing here is a trajectory that leads straight to the unthinkable.
It's a trajectory that was mapped out years ago with the full awareness of the human consequences.
But who was it that put us on this course?
What kind of psychopath is willing to intentionally set off a global conflict that would lead to millions of deaths just to protect the value of a paper currency?
It obviously isn't the President.
The decision to invade Libya, Syria and Iran was made long before Obama had risen to the national spotlight.
And yet he's carrying out his duty just like the puppets that preceded him.
So who is it that pulls the strings?
Often the best answer to questions like these are found by asking another question. Cui bono? Who benefits?
Obviously, those who have the power to print the dollar out of thin air have the most to lose if the dollar was to fall.
Since 1913, that power has been held by the Federal Reserve.
The Federal Reserve is a private entity, owned by a conglomerate of the most powerful banks in the world.
And the men who control those banks are the ones who pull the strings.
To them, this is just a game.
Your life and the lives of those you love are just pawns on their chess board.
And like a spoiled four year old who tips the board on to the floor when he starts to lose, the powers that be are willing to start World War ill to keep control of the global financial system.
Remember that when these wars extend and accelerate. Remember that when your son or your neighbor's son comes back home in a flag draped coffin. Remember that when they point the finger at the new boogeyman.
Because the madmen that are running this show will take this as far as you allow them to.
So how much time do we have left?
It's a question I hear constantly, but it's the wrong question.
Asking how much time we have left is a passive posture.
It's the attitude of a prisoner who is waiting to be taken out to a ditch and be shot in the back of the head.
What are our chances?
Can we change course?
Also the wrong question.
If you understand what we are facing then you have a moral responsibility to do everything in your power to alter the course that we're on regardless of the odds.
It's only when you stop basing your involvement on the chances of success that success actually becomes possible.
To strip the ill begotten power from the financial elites and to bring these criminal cartels to justice will requiere nothing less than a revolution and government is not going to save us. The government is completely infiltrated and corrupt to the core
looking to them for a solution at this point is utterly naive.
There are 3 stages of revolution and they're sequential.
Stage one is already under way.
Stage one is the ideological resistance.
At this stage we have to actively work to wake up as many people as possible about what is happening and the direction we're headed.
All revolutions originate from a shift to the mindset of the population and no other meaningful resistance is possible without it.
Success at this stage of the game can be measured by the contagion of ideas.
When an idea reaches critical mass it begins to spread on its own and seeps into all levels of society.
In order to achieve that contagion we need more people in this fight.
We need more people speaking out, making videos, writing articles, getting this information onto the national and international stage, and we especially need to reach the police and the military.
Stage two is civil disobedience, also known as non-violent resistance.
In this stage you put your money where your mouth is, or more accurately you withhold your money and your obedience from government, and you do everything in your power to bring the gears of the state to a halt.
Practiced in mass this method alone is often enough to bring a regime to its knees. However if you fail at this stage, stage 3 is inevitable.
Stage 3 is direct physical resistance.
Direct physical resistance is the last resort and it should be avoided and delayed as long as possible, and should only be invoked once all other options have been thoroughly exhausted.
There are those who talk tough and claim that they will resist when the time comes, but what those people fail to realize is that if you are inactive during the first two stages and save your efforts for the last resistance then you will fail.
When the Nazis were moving door to door dragging people out of their homes in Germany that was the time to fight back physically. But due to the lack of ideological resistance and civil disobedience leading up to that moment even an armed uprising would have likely failed at that point.
An armed uprising can only succeed if the people have established an attitude of active resistance, and active resistance is only possible after their minds have broken free from mainstream propaganda.
If you want to fight back it's now or never.
You're not gonna get another chance and the stakes are far higher than they were in Nazi Germany.
Rewrite the expression 4 times, and then in parentheses we have 8 plus 3, using the distributive law of multiplication over addition. Then simplify the expression. So let's just try to solve this or evaluate this expression, then we'll talk a little bit about the distributive law of multiplication over addition, usually just called the distributive law.
8 plus 3 is 11. So if we do that-- let me do that in this direction. So if we do that, we get 4 times, and in parentheses we have an 11.
8 plus 3 is 11, and then this is going to be equal to-- well, 4 times 11 is just 44, so you can evaluate it that way.
But they want us to use the distributive law of multiplication. We did not use the distributive law just now. We just evaluated the expression.
4 times 3 is 12 and 32 plus 12 is equal to 44. That is also equal to 44, so you can get it either way. But when they want us to use the distributive law, you'd distribute the 4 first.
And then we're going to add to that three of something, of maybe the same thing. One, two, three. So you can imagine this is what we have inside of the parentheses.
If you were to count all of this stuff, you would get 44. But what is this thing over here? Well, that's 8 added to itself four times.
How does the news shape the way we see the world? Here's the world based on the way it looks -- based on landmass. And here's how news shapes what Americans see.
Add. Simplify the answer and write as a mixed number. And we have three mixed numbers here:
So we have 3 plus 11 plus 4, and then we can add the fractions: the 1/12 plus 2/5 plus 3/15. Now, the blue part's pretty straightforward. We're just adding numbers.
3 plus 11 is 14 plus 4 is 18, so that part right there is just 18. This will be a little bit trickier, because we know that when we add fractions, we have to have the same denominator. And now we have to make all three of these characters have the same denominator and that denominator has to be the
15 is 3 times 5, and now both of these are prime. So we need something that has two 2's and a 3, so let's look at the 12 right there. So our denominator has to have at least two 2's and a 3, so
5's another one of those prime factors, so it's got to have a 5 in there. It didn't already have a 5. And then it also has to have a 3 and a 5.
2 times 2 is 4.
4 times 3 is 12.
12 times 5 is 60. So the least common multiple of 12, 5 and 15 is 60. So this is going to be plus.
5/60 is the same thing as 1/12. To go from 5 to 60 in the denominator, we have to multiply by 12, so we have to do the same thing for the numerator.
12 times 2 is 24. The last one, 15 to 60, you have to multiply by 4, so you have to do the same thing in the numerator.
4 times 3 is 12. And now we have the same denominator. We are ready to add.
29 plus 12, let's see, 29 plus 10 would be 39 plus 2 would be 41. It would be 41. And as far as I can tell, 41 and 60 do not have any common factors.
So one of the the YouTube viewers asked me to do this problem. And it looked like a pretty good problem. So I thought I would record a quick video on it.
-- is equal to 2 times the square root of x squared plus 1 minus 1, all of that over the square root of x squared plus 1 plus 1. And f of x is equal to 2x minus 1 over x plus 1. And the question is, if we know that f of g of x is equal to this fairly complex-looking expression, and that f of x is equal to this, than what is g of x?
2 times something minus 1. 2 times something minus 1 in the numerator, and that's something plus 1 in the denominator. And that's something plus 1 in the denominator.
I want to do it, let's see if I can do it in
-- oh, there we go. Better. All right.
How are you! Beautiful! How are you?
Very well thank you. Very well thank you. Goodbye!
Goodbye!
Welcome to my presentation on domain of a function. So what's is the domain? The domain of a function, you'll often hear it combined with domain and range.
So let me ask you a question. What values of x can I put in here so I get a valid answer for x squared? Well, I can really put anything in here, any real number.
So let's say I had f of x is equal to 1 over x squared. So is this same thing now? Can I still put any x value in here and get a reasonable answer?
Well what's f of 0? f of zero is equal to 1 over 0. And what's 1 over 0?
No one ever took the trouble to define what 1 over 0 should be. And they probably didn't do, so some people probably thought about what should be, but they probably couldn't find out with a good definition for 1 over 0 that's consistent with the rest of mathematics. So 1 over 0 stays undefined.
Let's do a slightly more difficult one. What if I said f of x is equal to the square root of the absolute value of x minus 3. So now it's getting a little bit more complicated.
It has to be further in the negative direction than negative 3, or it has to be further in the positive direction than positive 3. So, once again, x has to be less than negative 3 or x has to be greater than 3, so we have our domain. So we have it as x is a member of the reals
It could be any real number here, as long as x is less than negative 3, less than or equal to negative 3, or x is greater than or equal to 3. Let me ask a question now. What if instead of this it was -- that was the denominator, this is all a separate problem up here.
Let me erase this. OK. Now let's say that f of x is equal to 2, if x is even, and 1 over x minus 2 times x minus 1, if x is odd.

SAMPSON True; and therefore women, being the weaker vessels, are ever thrust to the wall: therefore I will push Montague's men from the wall and thrust his maids to the wall. GREGORY The quarrel is between our masters and us their men.
SAMPSON 'Tis all one, I will show myself a tyrant: when I have fought with the men I will be cruel with the maids, I will cut off their heads. GREGORY The heads of the maids?
SAMPSON Ay, the heads of the maids, or their maidenheads; take it in what sense thou wilt. GREGORY They must take it in sense that feel it. SAMPSON Me they shall feel while I am able to stand: and 'tis known I am a pretty piece of flesh.
SAMPSON My naked weapon is out: quarrel! I will back thee. GREGORY How! turn thy back and run?
SAMPSON Fear me not. GREGORY No, marry; I fear thee!
SAMPSON Let us take the law of our sides; let them begin. GREGORY I will frown as I pass by; and let them take it as they list.
SAMPSON Nay, as they dare. I will bite my thumb at them; which is disgrace to them if they bear it. [Enter Abraham and Balthasar.]
ABRAHAM Do you bite your thumb at us, sir?
SAMPSON I do bite my thumb, sir. ABRAHAM Do you bite your thumb at us, sir?
SAMPSON Is the law of our side if I say ay? GREGORY No.
SAMPSON No, sir, I do not bite my thumb at you, sir; but I bite my thumb, sir. GREGORY Do you quarrel, sir? ABRAHAM Quarrel, sir! no, sir.
SAMPSON But if you do, sir, am for you: I serve as good a man as you. ABRAHAM No better.
SAMPSON Yes, better, sir. ABRAHAM You lie.
SAMPSON Draw, if you be men.--Gregory, remember thy swashing blow.
[They fight.]
[Enter Benvolio.]
BENVOLlO Part, fools! put up your swords; you know not what you do.
[Beats down their swords.]
[Enter Tybalt.] TYBALT What, art thou drawn among these heartless hinds? Turn thee Benvolio, look upon thy death.
BENVOLlO I do but keep the peace: put up thy sword, Or manage it to part these men with me. TYBALT What, drawn, and talk of peace! I hate the word
Have at thee, coward!
Down with the Montagues!
[Enter Capulet in his gown, and Lady Capulet.]
CAPULET What noise is this?--Give me my long sword, ho! LADY CAPULET A crutch, a crutch!--Why call you for a sword?
CAPULET My sword, I say!--Old Montague is come, And flourishes his blade in spite of me.
[Enter Montague and his Lady Montague.] MONTAGUE Thou villain Capulet!-- Hold me not, let me go. LADY MONTAGUE Thou shalt not stir one foot to seek a foe.
[Enter Prince, with Attendants.] PRlNCE Rebellious subjects, enemies to peace, Profaners of this neighbour-stained steel,-- Will they not hear?--What, ho! you men, you beasts, That quench the fire of your pernicious rage
Once more, on pain of death, all men depart. [Exeunt Prince and Attendants; Capulet, Lady Capulet, Tybalt, Citizens, and Servants.]
MONTAGUE Who set this ancient quarrel new abroach?-- Speak, nephew, were you by when it began? BENVOLlO Here were the servants of your adversary And yours, close fighting ere I did approach:
BENVOLlO Madam, an hour before the worshipp'd sun Peer'd forth the golden window of the east, A troubled mind drave me to walk abroad; Where,--underneath the grove of sycamore That westward rooteth from the city's side,-- So early walking did I see your son:
MONTAGUE Many a morning hath he there been seen, With tears augmenting the fresh morning's dew, Adding to clouds more clouds with his deep sighs: But all so soon as the all-cheering sun Should in the farthest east begin to draw
BENVOLlO My noble uncle, do you know the cause?
MONTAGUE I neither know it nor can learn of him.
BENVOLlO Have you importun'd him by any means? MONTAGUE Both by myself and many other friends; But he, his own affections' counsellor, Is to himself,--I will not say how true,--
BENVOLlO See, where he comes: so please you step aside; I'll know his grievance or be much denied.
MONTAGUE I would thou wert so happy by thy stay To hear true shrift.--Come, madam, let's away, [Exeunt Montague and Lady.] [Enter Romeo.]
BENVOLlO Good morrow, cousin. ROMEO Is the day so young?
BENVOLlO But new struck nine. ROMEO Ay me! sad hours seem long. Was that my father that went hence so fast?
BENVOLlO It was.--What sadness lengthens Romeo's hours? ROMEO Not having that which, having, makes them short. BENVOLlO In love?
BENVOLlO No, coz, I rather weep. ROMEO Good heart, at what? BENVOLlO At thy good heart's oppression.
[Going.]
BENVOLlO Soft! I will go along: An if you leave me so, you do me wrong.
BENVOLlO Tell me in sadness who is that you love? ROMEO What, shall I groan and tell thee?
BENVOLlO Groan! why, no; But sadly tell me who. ROMEO Bid a sick man in sadness make his will,--
BENVOLlO I aim'd so near when I suppos'd you lov'd. ROMEO A right good markman!--And she's fair I love.
BENVOLlO A right fair mark, fair coz, is soonest hit. ROMEO Well, in that hit you miss: she'll not be hit With Cupid's arrow,--she hath Dian's wit; And, in strong proof of chastity well arm'd,
BENVOLlO Then she hath sworn that she will still live chaste? ROMEO She hath, and in that sparing makes huge waste; For beauty, starv'd with her severity, Cuts beauty off from all posterity.
BENVOLlO Be rul'd by me, forget to think of her. ROMEO O, teach me how I should forget to think. BENVOLlO By giving liberty unto thine eyes;
[Exeunt.]

[Enter Capulet, Paris, and Servant.]
CAPULET But Montague is bound as well as I, In penalty alike; and 'tis not hard, I think, For men so old as we to keep the peace. PARlS Of honourable reckoning are you both;
CAPULET But saying o'er what I have said before: My child is yet a stranger in the world, She hath not seen the change of fourteen years; Let two more summers wither in their pride Ere we may think her ripe to be a bride.
CAPULET And too soon marr'd are those so early made. The earth hath swallowed all my hopes but she,-- She is the hopeful lady of my earth: But woo her, gentle Paris, get her heart, My will to her consent is but a part;
[Exeunt Capulet and Paris]. SERVANT Find them out whose names are written here! It is written that the shoemaker should meddle with his yard and the tailor with his last, the fisher with his pencil, and the painter with his nets; but I am sent to find those persons whose names are here writ, and can never find what names the writing person hath here writ.
I must to the learned:--in good time! [Enter Benvolio and Romeo.]
BENVOLlO Tut, man, one fire burns out another's burning, One pain is lessen'd by another's anguish; Turn giddy, and be holp by backward turning; One desperate grief cures with another's languish:
BENVOLlO For what, I pray thee? ROMEO For your broken shin.
BENVOLlO Why, Romeo, art thou mad? ROMEO Not mad, but bound more than a madman is; Shut up in prison, kept without my food, Whipp'd and tormented and--God-den, good fellow.
ROMEO Stay, fellow; I can read. [Reads.]
'Signior Martino and his wife and daughters; County Anselmo and his beauteous sisters; the lady widow of Vitruvio; Signior Placentio and his lovely nieces; Mercutio and his brother Valentine; mine uncle Capulet, his wife, and daughters; my fair niece Rosaline; Livia; Signior Valentio and his cousin Tybalt; Lucio and the [Gives back the paper]: whither should they come?
[Exit.]
BENVOLlO At this same ancient feast of Capulet's Sups the fair Rosaline whom thou so lov'st; With all the admired beauties of Verona. Go thither; and, with unattainted eye,
BENVOLlO Tut, you saw her fair, none else being by, Herself pois'd with herself in either eye: But in that crystal scales let there be weigh'd Your lady's love against some other maid That I will show you shining at this feast, And she shall scant show well that now shows best.

JULlET How now, who calls? NURSE Your mother. JULlET Madam, I am here.
Than your consent gives strength to make it fly. [Enter a Servant.] SERVANT Madam, the guests are come, supper served up, you called, my young lady asked for, the nurse cursed in the pantry, and everything in extremity.
LADY CAPULET We follow thee. [Exit Servant.]-- Juliet, the county stays.
[Exeunt.] Scene IV.
[Enter Romeo, Mercutio, Benvolio, with five or six Maskers; Torch-bearers, and others.] ROMEO What, shall this speech be spoke for our excuse?
BENVOLlO The date is out of such prolixity: We'll have no Cupid hoodwink'd with a scarf, Bearing a Tartar's painted bow of lath, Scaring the ladies like a crow-keeper; Nor no without-book prologue, faintly spoke
MERCUTlO Nay, gentle Romeo, we must have you dance. ROMEO Not I, believe me: you have dancing shoes, With nimble soles; I have a soul of lead So stakes me to the ground I cannot move.
MERCUTlO You are a lover; borrow Cupid's wings, And soar with them above a common bound. ROMEO I am too sore enpierced with his shaft To soar with his light feathers; and so bound, I cannot bound a pitch above dull woe:
MERCUTlO If love be rough with you, be rough with love; Prick love for pricking, and you beat love down.-- Give me a case to put my visage in: [Putting on a mask.]
MERCUTlO Tut, dun's the mouse, the constable's own word: If thou art dun, we'll draw thee from the mire Of this--sir-reverence--love, wherein thou stick'st Up to the ears.--Come, we burn daylight, ho.
MERCUTlO I mean, sir, in delay We waste our lights in vain, like lamps by day. Take our good meaning, for our judgment sits
MERCUTlO Why, may one ask? ROMEO I dreamt a dream to-night.
MERCUTlO And so did I. ROMEO Well, what was yours?
MERCUTlO That dreamers often lie. ROMEO In bed asleep, while they do dream things true.
MERCUTlO O, then, I see Queen Mab hath been with you. She is the fairies' midwife; and she comes In shape no bigger than an agate-stone On the fore-finger of an alderman, Drawn with a team of little atomies
O'er ladies' lips, who straight on kisses dream,-- Which oft the angry Mab with blisters plagues, Because their breaths with sweetmeats tainted are: Sometime she gallops o'er a courtier's nose,
MERCUTlO True, I talk of dreams, Which are the children of an idle brain, Begot of nothing but vain fantasy; Which is as thin of substance as the air, And more inconstant than the wind, who wooes Even now the frozen bosom of the north,
BENVOLlO This wind you talk of blows us from ourselves: Supper is done, and we shall come too late. ROMEO I fear, too early: for my mind misgives
BENVOLlO Strike, drum.

2 SERVANT When good manners shall lie all in one or two men's hands, and they unwash'd too, 'tis a foul thing.
1 SERVANT Away with the join-stools, remove the court-cupboard, look to the plate:--good thou, save me a piece of marchpane; and as thou loves me, let the porter let in Susan Grindstone and Nell.-- Antony! and Potpan!
2 SERVANT Ay, boy, ready. 1 SERVANT You are looked for and called for, asked for and sought for in the great chamber. 2 SERVANT We cannot be here and there too.--Cheerly, boys; be brisk awhile, and the longer liver take all.
[They retire behind.]
[Enter Capulet, &c. with the Guests the Maskers.]
CAPULET Welcome, gentlemen! ladies that have their toes Unplagu'd with corns will have a bout with you.-- Ah ha, my mistresses! which of you all Will now deny to dance? she that makes dainty, she, I'll swear hath corns; am I come near you now?
2 CAPULET By'r Lady, thirty years.
CAPULET What, man! 'tis not so much, 'tis not so much:
'Tis since the nuptial of Lucentio, Come Pentecost as quickly as it will, Some five-and-twenty years; and then we mask'd.
2 CAPULET 'Tis more, 'tis more: his son is elder, sir; His son is thirty.
CAPULET Will you tell me that? His son was but a ward two years ago. ROMEO What lady is that, which doth enrich the hand Of yonder knight?
CAPULET Why, how now, kinsman! wherefore storm you so? TYBALT Uncle, this is a Montague, our foe; A villain, that is hither come in spite, To scorn at our solemnity this night.
CAPULET Young Romeo, is it? TYBALT 'Tis he, that villain, Romeo.
CAPULET Content thee, gentle coz, let him alone, He bears him like a portly gentleman; And, to say truth, Verona brags of him To be a virtuous and well-govern'd youth:
CAPULET He shall be endur'd: What, goodman boy!--I say he shall;--go to; Am I the master here, or you? go to. You'll not endure him!--God shall mend my soul, You'll make a mutiny among my guests!
CAPULET Go to, go to! You are a saucy boy. Is't so, indeed?-- This trick may chance to scathe you,--I know what:
Now seeming sweet, convert to bitter gall. [Exit.] ROMEO [To Juliet.]
Thus from my lips, by thine my sin is purg'd. [Kissing her.] JULlET Then have my lips the sin that they have took.
Shall have the chinks. ROMEO Is she a Capulet?
BENVOLlO Away, be gone; the sport is at the best. ROMEO Ay, so I fear; the more is my unrest.
CAPULET Nay, gentlemen, prepare not to be gone; We have a trifling foolish banquet towards.-- Is it e'en so? why then, I thank you all; I thank you, honest gentlemen; good-night.-- More torches here!--Come on then, let's to bed.
[Exeunt all but Juliet and Nurse.] JULlET Come hither, nurse.
What is yond gentleman? NURSE The son and heir of old Tiberio. JULlET What's he that now is going out of door?

Anon, anon! Come, let's away; the strangers all are gone.

ROMEO Can I go forward when my heart is here? Turn back, dull earth, and find thy centre out.
[He climbs the wall and leaps down within it.]
[Enter Benvolio and Mercutio.]
BENVOLlO Romeo! my cousin Romeo!
MERCUTlO He is wise; And, on my life, hath stol'n him home to bed.
BENVOLlO He ran this way, and leap'd this orchard wall: Call, good Mercutio.
MERCUTlO Nay, I'll conjure too.-- Romeo! humours! madman! passion! lover! Appear thou in the likeness of a sigh:
BENVOLlO An if he hear thee, thou wilt anger him. MERCUTlO This cannot anger him: 'twould anger him To raise a spirit in his mistress' circle,
Of some strange nature, letting it there stand Till she had laid it, and conjur'd it down; That were some spite: my invocation Is fair and honest, and, in his mistress' name, I conjure only but to raise up him.
BENVOLlO Come, he hath hid himself among these trees, To be consorted with the humorous night: Blind is his love, and best befits the dark.
MERCUTlO If love be blind, love cannot hit the mark. Now will he sit under a medlar tree, And wish his mistress were that kind of fruit As maids call medlars when they laugh alone.-- Romeo, good night.--I'll to my truckle-bed;
To seek him here that means not to be found. [Exeunt.] Scene Il.

What's Montague? It is nor hand, nor foot, Nor arm, nor face, nor any other part Belonging to a man.
Anon, good nurse!--Sweet Montague, be true. Stay but a little, I will come again.
[Exit.]
ROMEO O blessed, blessed night! I am afeard, Being in night, all this is but a dream, Too flattering-sweet to be substantial.
[Enter Juliet above.] JULlET Three words, dear Romeo, and good night indeed. If that thy bent of love be honourable, Thy purpose marriage, send me word to-morrow,
[Exit.]
ROMEO A thousand times the worse, to want thy light!-- Love goes toward love as schoolboys from their books; But love from love, towards school with heavy looks.
[Retiring slowly.] [Re-enter Juliet, above.] JULlET Hist!
That I shall say good night till it be morrow. [Exit.] ROMEO Sleep dwell upon thine eyes, peace in thy breast!--

Full soon the canker death eats up that plant. [Enter Romeo.] ROMEO Good morrow, father!
Doth couch his limbs, there golden sleep doth reign: Therefore thy earliness doth me assure Thou art uprous'd with some distemperature; Or if not so, then here I hit it right,--
FRlAR God pardon sin! wast thou with Rosaline? ROMEO With Rosaline, my ghostly father? no; I have forgot that name, and that name's woe. FRlAR That's my good son: but where hast thou been then?
Is Rosaline, that thou didst love so dear, So soon forsaken? young men's love, then, lies Not truly in their hearts, but in their eyes.
Jesu Maria, what a deal of brine
Hath wash'd thy sallow cheeks for Rosaline! How much salt water thrown away in waste, To season love, that of it doth not taste!

Scene IV. A Street.
[Enter Benvolio and Mercutio.]
MERCUTlO Where the devil should this Romeo be?-- Came he not home to-night?
BENVOLlO Not to his father's; I spoke with his man.
MERCUTlO Ah, that same pale hard-hearted wench, that Rosaline,
Torments him so that he will sure run mad.
BENVOLlO Tybalt, the kinsman to old Capulet, Hath sent a letter to his father's house.
MERCUTlO A challenge, on my life.
BENVOLlO Romeo will answer it.
MERCUTlO Any man that can write may answer a letter.
BENVOLlO Nay, he will answer the letter's master, how he dares, being dared. MERCUTlO Alas, poor Romeo, he is already dead! stabbed with a white wench's black eye; shot through the ear with a love song; the very pin of his heart cleft with the blind bow-boy's butt-shaft: and is he a man to encounter Tybalt?
BENVOLlO Why, what is Tybalt?
MERCUTlO More than prince of cats, I can tell you. O, he's the courageous captain of compliments. He fights as you sing prick-song--keeps time, distance, and proportion; rests me his minim rest, one, two, and the third in your bosom: the very butcher of a silk button, a duellist, a duellist; a gentleman of the very first house,--of the first and second cause: ah, the immortal passado! the punto reverso! the hay.--
BENVOLlO The what?
MERCUTlO The pox of such antic, lisping, affecting fantasticoes; these new tuners of accents!--'By Jesu, a very good blade!--a very tall man!--a very good whore!'--Why, is not this a lamentable thing, grandsire, that we should be thus afflicted with these strange flies, these fashion-mongers, these pardonnez-moi's, who stand so much on the new form that they cannot sit at ease on the old bench?
BENVOLlO Here comes Romeo, here comes Romeo! MERCUTlO Without his roe, like a dried herring.--O flesh, flesh, how art thou fishified!--Now is he for the numbers that Petrarch flowed in: Laura, to his lady, was but a kitchen wench,--marry, she had a better love to be-rhyme her; Dido, a dowdy; Cleopatra, a gypsy; Helen and Hero, hildings and harlots; Thisbe, a gray eye or so, but not to the purpose,-- [Enter Romeo.]
Signior Romeo, bon jour! there's a French salutation to your French slop. You gave us the counterfeit fairly last night. ROMEO Good morrow to you both.
MERCUTlO The slip, sir, the slip; can you not conceive? ROMEO Pardon, good Mercutio, my business was great; and in such a case as mine a man may strain courtesy.
MERCUTlO That's as much as to say, such a case as yours constrains a man to bow in the hams. ROMEO Meaning, to court'sy.
MERCUTlO Thou hast most kindly hit it. ROMEO A most courteous exposition.
MERCUTlO Nay, I am the very pink of courtesy. ROMEO Pink for flower.
MERCUTlO Right. ROMEO Why, then is my pump well-flowered.
MERCUTlO Well said: follow me this jest now till thou hast worn out thy pump;that, when the single sole of it is worn, the jest may remain, after the wearing, sole singular. ROMEO O single-soled jest, solely singular for the singleness!
MERCUTlO Come between us, good Benvolio; my wits faint. ROMEO Swits and spurs, swits and spurs; or I'll cry a match. MERCUTlO Nay, if thy wits run the wild-goose chase, I have done; for thou hast more of the wild-goose in one of thy wits than, I am sure, I have in my whole five: was I with you there for the goose?
MERCUTlO I will bite thee by the ear for that jest. ROMEO Nay, good goose, bite not.
MERCUTlO Thy wit is a very bitter sweeting; it is a most sharp sauce. ROMEO And is it not, then, well served in to a sweet goose?
MERCUTlO O, here's a wit of cheveril, that stretches from an inch narrow to an ell broad! ROMEO I stretch it out for that word broad: which added to the goose, proves thee far and wide a broad goose.
MERCUTlO Why, is not this better now than groaning for love? now art thou sociable, now art thou Romeo; not art thou what thou art, by art as well as by nature: for this drivelling love is like a great natural, that runs lolling up and down to hide his bauble in a hole.
BENVOLlO Stop there, stop there. MERCUTlO Thou desirest me to stop in my tale against the hair.
BENVOLlO Thou wouldst else have made thy tale large.
MERCUTlO O, thou art deceived; I would have made it short: for I was come to the whole depth of my tale; and meant indeed to occupy the argument no longer. ROMEO Here's goodly gear!
[Enter Nurse and Peter.]
MERCUTlO A sail, a sail, a sail!
BENVOLlO Two, two; a shirt and a smock. NURSE Peter! PETER Anon.
MERCUTlO Good Peter, to hide her face; for her fan's the fairer face. NURSE God ye good morrow, gentlemen.
MERCUTlO God ye good-den, fair gentlewoman. NURSE Is it good-den?
MERCUTlO 'Tis no less, I tell ye; for the bawdy hand of the dial is now upon the prick of noon. NURSE Out upon you! what a man are you! ROMEO One, gentlewoman, that God hath made for himself to mar.
MERCUTlO Yea, is the worst well? very well took, i' faith; wisely, wisely. NURSE If you be he, sir, I desire some confidence with you.
BENVOLlO She will indite him to some supper.
MERCUTlO A bawd, a bawd, a bawd! So ho! ROMEO What hast thou found?
MERCUTlO No hare, sir; unless a hare, sir, in a lenten pie, that is something stale and hoar ere it be spent.
[Sings.] An old hare hoar, And an old hare hoar, Is very good meat in Lent; But a hare that is hoar
MERCUTlO Farewell, ancient lady; farewell,-- [singing] lady, lady, lady.
[Exeunt Mercutio, and Benvolio.] NURSE Marry, farewell!--I pray you, sir, what saucy merchant was this that was so full of his ropery? ROMEO A gentleman, nurse, that loves to hear himself talk; and will speak more in a minute than he will stand to in a month.
NURSE An 'a speak anything against me, I'll take him down, an'a were lustier than he is, and twenty such Jacks; and if I cannot, I'll find those that shall. Scurvy knave!
I am none of his flirt-gills; I am none of his skains-mates.--And thou must stand by too, and suffer every knave to use me at his pleasure! PETER I saw no man use you at his pleasure; if I had, my weapon should quickly have been out, I warrant you: I dare draw as soon as another man, if I see occasion in a good quarrel, and the law on my side.

BENVOLlO I pray thee, good Mercutio, let's retire: The day is hot, the Capulets abroad, And, if we meet, we shall not scape a brawl; For now, these hot days, is the mad blood stirring.
MERCUTlO Thou art like one of these fellows that, when he enters the confines of a tavern, claps me his sword upon the table, and says 'God send me no need of thee!' and by the operation of the second cup draws him on the drawer, when indeed there is no need.
BENVOLlO Am I like such a fellow?
MERCUTlO Come, come, thou art as hot a Jack in thy mood as any in Italy; and as soon moved to be moody, and as soon moody to be moved.
BENVOLlO And what to?
MERCUTlO Nay, an there were two such, we should have none shortly, for one would kill the other. Thou! why, thou wilt quarrel with a man that hath a hair more or a hair less in his beard than thou hast. Thou wilt quarrel with a man for cracking nuts, having no other reason but because thou hast hazel eyes;--what eye but such an eye would spy out such a quarrel?
Didst thou not fall out with a tailor for wearing his new doublet before Easter? with another for tying his new shoes with an old riband? and yet thou wilt tutor me from quarrelling! BENVOLlO An I were so apt to quarrel as thou art, any man should buy the fee simple of my life for an hour and a quarter. MERCUTlO The fee simple!
BENVOLlO By my head, here come the Capulets. MERCUTlO By my heel, I care not.
[Enter Tybalt and others.] TYBALT Follow me close, for I will speak to them.--Gentlemen, good-den: a word with one of you.
MERCUTlO And but one word with one of us? Couple it with something; make it a word and a blow. TYBALT You shall find me apt enough to that, sir, an you will give me occasion.
MERCUTlO Could you not take some occasion without giving? TYBALT Mercutio, thou consortest with Romeo,--
MERCUTlO Consort! what, dost thou make us minstrels? An thou make minstrels of us, look to hear nothing but discords: here's my fiddlestick; here's that shall make you dance. Zounds, consort!
BENVOLlO We talk here in the public haunt of men: Either withdraw unto some private place, And reason coldly of your grievances, Or else depart; here all eyes gaze on us.
MERCUTlO Men's eyes were made to look, and let them gaze; I will not budge for no man's pleasure, I. TYBALT Well, peace be with you, sir.--Here comes my man.
[Enter Romeo.]
MERCUTlO But I'll be hanged, sir, if he wear your livery: Marry, go before to field, he'll be your follower; Your worship in that sense may call him man. TYBALT Romeo, the love I bear thee can afford
MERCUTlO O calm, dishonourable, vile submission! Alla stoccata carries it away.
[Draws.] Tybalt, you rat-catcher, will you walk? TYBALT What wouldst thou have with me?
MERCUTlO Good king of cats, nothing but one of your nine lives; that I mean to make bold withal, and, as you shall use me hereafter, dry-beat the rest of the eight. Will you pluck your sword out of his pitcher by the ears? make haste, lest mine be about your ears ere it be out. TYBALT I am for you.
[Drawing.] ROMEO Gentle Mercutio, put thy rapier up.
MERCUTlO Come, sir, your passado.

ROMEO Draw, Benvolio; beat down their weapons.-- Gentlemen, for shame! forbear this outrage!-- Tybalt,--Mercutio,--the prince expressly hath Forbid this bandying in Verona streets.--
Hold, Tybalt!--good Mercutio!-- [Exeunt Tybalt with his Partizans.]
MERCUTlO I am hurt;-- A plague o' both your houses!--I am sped.-- Is he gone, and hath nothing?
BENVOLlO What, art thou hurt?
MERCUTlO Ay, ay, a scratch, a scratch; marry, 'tis enough.-- Where is my page?--go, villain, fetch a surgeon.
[Exit Page.] ROMEO Courage, man; the hurt cannot be much.
MERCUTlO No, 'tis not so deep as a well, nor so wide as a church door; but 'tis enough, 'twill serve: ask for me to-morrow, and you shall find me a grave man.
I am peppered, I warrant, for this world.--A plague o' both your houses!--Zounds, a dog, a rat, a mouse, a cat, to scratch a man to death! a braggart, a rogue, a villain, that fights by the book of arithmetic!--Why the devil came you between us? I was hurt under your arm. ROMEO I thought all for the best.
MERCUTlO Help me into some house, Benvolio, Or I shall faint.--A plague o' both your houses! They have made worms' meat of me:
I have it, and soundly too.--Your houses! [Exit Mercutio and Benvolio.] ROMEO This gentleman, the prince's near ally,

BENVOLlO Here comes the furious Tybalt back again. ROMEO Alive in triumph! and Mercutio slain! Away to heaven respective lenity, And fire-ey'd fury be my conduct now!--
[Re-enter Tybalt.] Now, Tybalt, take the 'villain' back again That late thou gavest me; for Mercutio's soul Is but a little way above our heads,
[They fight; Tybalt falls.]
BENVOLlO Romeo, away, be gone! The citizens are up, and Tybalt slain.-- Stand not amaz'd.
BENVOLlO Why dost thou stay?
[Exit Romeo.]
[Enter Citizens, &c.] 1 ClTIZEN Which way ran he that kill'd Mercutio? Tybalt, that murderer, which way ran he?
BENVOLlO There lies that Tybalt.
1 ClTIZEN Up, sir, go with me; I charge thee in the prince's name obey.
[Enter Prince, attended; Montague, Capulet, their Wives, and others.]
PRlNCE Where are the vile beginners of this fray?
BENVOLlO O noble prince. I can discover all The unlucky manage of this fatal brawl:
For blood of ours shed blood of Montague.-- O cousin, cousin! PRlNCE Benvolio, who began this bloody fray?
BENVOLlO Tybalt, here slain, whom Romeo's hand did slay; Romeo, that spoke him fair, bid him bethink How nice the quarrel was, and urg'd withal Your high displeasure.--All this,--uttered With gentle breath, calm look, knees humbly bow'd,--
'Hold, friends! friends, part!' and swifter than his tongue, His agile arm beats down their fatal points, And 'twixt them rushes; underneath whose arm An envious thrust from Tybalt hit the life Of stout Mercutio, and then Tybalt fled:

Towards Phoebus' lodging; such a waggoner As Phaeton would whip you to the west And bring in cloudy night immediately.-- Spread thy close curtain, love-performing night! That rude eyes may wink, and Romeo Leap to these arms, untalk'd of and unseen.--
[Throws them down.] JULlET Ah me! what news? why dost thou wring thy hands? NURSE Ah, well-a-day! he's dead, he's dead, he's dead!
Despised substance of divinest show! Just opposite to what thou justly seem'st, A damned saint, an honourable villain!-- O nature, what hadst thou to do in hell When thou didst bower the spirit of a fiend

FRlAR Arise; one knocks. Good Romeo, hide thyself. ROMEO Not I; unless the breath of heartsick groans,
[Knocking.] FRlAR Hark, how they knock!--Who's there?--Romeo, arise; Thou wilt be taken.--Stay awhile;--Stand up; [Knocking.]
[Knocking.] Who knocks so hard? whence come you? what's your will?
NURSE [Within.] Let me come in, and you shall know my errand; I come from Lady Juliet.
[Enter Nurse.]
NURSE O holy friar, O, tell me, holy friar, Where is my lady's lord, where's Romeo? FRlAR There on the ground, with his own tears made drunk. NURSE O, he is even in my mistress' case,--
Piteous predicament! NURSE Even so lies she,
Blubbering and weeping, weeping and blubbering.-- Stand up, stand up; stand, an you be a man: For Juliet's sake, for her sake, rise and stand; Why should you fall into so deep an O? ROMEO Nurse!
With blood remov'd but little from her own? Where is she? and how doth she? and what says My conceal'd lady to our cancell'd love?
The hateful mansion. [Drawing his sword.] FRlAR Hold thy desperate hand:
I thought thy disposition better temper'd. Hast thou slain Tybalt? wilt thou slay thyself? And slay thy lady, too, that lives in thee, By doing damned hate upon thyself?
Hie you, make haste, for it grows very late. [Exit.] ROMEO How well my comfort is reviv'd by this!

CAPULET Sir Paris, I will make a desperate tender Of my child's love: I think she will be rul'd In all respects by me; nay more, I doubt it not.--
CAPULET Monday! ha, ha! Well, Wednesday is too soon, Thursday let it be;--a Thursday, tell her, She shall be married to this noble earl.--

The day is broke; be wary, look about. [Exit.] JULlET Then, window, let day in, and let life out.

JULlET Art thou gone so? my lord, my love, my friend! I must hear from thee every day i' the hour, For in a minute there are many days:
Dry sorrow drinks our blood.
[Exit below.] JULlET O fortune, fortune! all men call thee fickle: If thou art fickle, what dost thou with him That is renown'd for faith?
[Enter Lady Capulet.] LADY CAPULET Why, how now, Juliet? JULlET Madam, I am not well.
LADY CAPULET That is because the traitor murderer lives. JULlET Ay, madam, from the reach of these my hands. Would none but I might venge my cousin's death!
[Enter Capulet and Nurse.]
CAPULET When the sun sets, the air doth drizzle dew; But for the sunset of my brother's son It rains downright.-- How now! a conduit, girl? what, still in tears? Evermore showering?
CAPULET Soft! take me with you, take me with you, wife. How! will she none? doth she not give us thanks? Is she not proud? doth she not count her bles'd,
CAPULET How now, how now, chop-logic! What is this? Proud,--and, I thank you,--and I thank you not;-- And yet not proud:--mistress minion, you,
CAPULET Hang thee, young baggage! disobedient wretch! I tell thee what,--get thee to church o' Thursday, Or never after look me in the face: Speak not, reply not, do not answer me; My fingers itch.--Wife, we scarce thought us bles'd
CAPULET And why, my lady wisdom? hold your tongue, Good prudence; smatter with your gossips, go. NURSE I speak no treason.
CAPULET O, God ye good-en! NURSE May not one speak?
CAPULET Peace, you mumbling fool! Utter your gravity o'er a gossip's bowl, For here we need it not. LADY CAPULET You are too hot.
CAPULET God's bread! it makes me mad: Day, night, hour, time, tide, work, play, Alone, in company, still my care hath been To have her match'd, and having now provided A gentleman of noble parentage,
Proportion'd as one's heart would wish a man,-- And then to have a wretched puling fool, A whining mammet, in her fortune's tender, To answer, 'I'll not wed,--I cannot love, I am too young,--I pray you pardon me:'-- But, an you will not wed, I'll pardon you:
[Exit.]
JULlET Is there no pity sitting in the clouds, That sees into the bottom of my grief? O, sweet my mother, cast me not away! Delay this marriage for a month, a week;
Do as thou wilt, for I have done with thee. [Exit.] JULlET O God!--O nurse! how shall this be prevented?
Alack, alack, that heaven should practise stratagems Upon so soft a subject as myself!-- What say'st thou? hast thou not a word of joy? Some comfort, nurse.
Romeo's a dishclout to him; an eagle, madam, Hath not so green, so quick, so fair an eye As Paris hath. Beshrew my very heart, I think you are happy in this second match,

CAPULET How canst thou try them so?
2 SERVANT Marry, sir, 'tis an ill cook that cannot lick his own fingers: therefore he that cannot lick his fingers goes not with me.
CAPULET Go, begone.-- [Exit second Servant.] We shall be much unfurnish'd for this time.--
CAPULET Well, be may chance to do some good on her: A peevish self-will'd harlotry it is. NURSE See where she comes from shrift with merry look.

CAPULET How now, my headstrong! where have you been gadding? JULlET Where I have learn'd me to repent the sin Of disobedient opposition To you and your behests; and am enjoin'd By holy Lawrence to fall prostrate here,
CAPULET Send for the county; go tell him of this: I'll have this knot knit up to-morrow morning. JULlET I met the youthful lord at Lawrence' cell;
CAPULET Go, nurse, go with her.--We'll to church to-morrow.

Alack, alack, is it not like that I, So early waking,--what with loathsome smells, And shrieks like mandrakes torn out of the earth, That living mortals, hearing them, run mad;-- O, if I wake, shall I not be distraught, Environed with all these hideous fears?

CAPULET Ha! let me see her:--out alas! she's cold; Her blood is settled, and her joints are stiff; Life and these lips have long been separated: Death lies on her like an untimely frost Upon the sweetest flower of all the field.

[Enter Balthasar.] News from Verona!--How now, Balthasar? Dost thou not bring me letters from the friar?
BALTHASAR Then she is well, and nothing can be ill: Her body sleeps in Capel's monument, And her immortal part with angels lives.
I will hence to-night. BALTHASAR I do beseech you, sir, have patience:
BALTHASAR No, my good lord. ROMEO No matter: get thee gone, And hire those horses; I'll be with thee straight.
[Exit Balthasar.] Well, Juliet, I will lie with thee to-night. Let's see for means;--O mischief, thou art swift To enter in the thoughts of desperate men!
In tatter'd weeds, with overwhelming brows, Culling of simples; meagre were his looks, Sharp misery had worn him to the bones; And in his needy shop a tortoise hung,
An alligator stuff'd, and other skins Of ill-shaped fishes; and about his shelves A beggarly account of empty boxes, Green earthen pots, bladders, and musty seeds, Remnants of packthread, and old cakes of roses, Were thinly scatter'd, to make up a show.
What, ho! apothecary! [Enter Apothecary.]
APOTHECARY Who calls so loud? ROMEO Come hither, man.--I see that thou art poor; Hold, there is forty ducats: let me have A dram of poison; such soon-speeding gear
APOTHECARY Such mortal drugs I have; but Mantua's law Is death to any he that utters them. ROMEO Art thou so bare and full of wretchedness And fear'st to die? famine is in thy cheeks, Need and oppression starveth in thine eyes,

Alack, alack! what blood is this which stains The stony entrance of this sepulchre?-- What mean these masterless and gory swords To lie discolour'd by this place of peace?
[Enters the monument.] Romeo! O, pale!--Who else? what, Paris too?
[Juliet wakes and stirs.] JULlET O comfortable friar! where is my lord?-- I do remember well where I should be, And there I am:--where is my Romeo?
[Noise within.] FRlAR I hear some noise.--Lady, come from that nest Of death, contagion, and unnatural sleep:
To help me after?--I will kiss thy lips; Haply some poison yet doth hang on them, To make me die with a restorative.

CAPULET O heaven!--O wife, look how our daughter bleeds! This dagger hath mista'en,--for, lo, his house Is empty on the back of Montague,-- And it mis-sheathed in my daughter's bosom!
That warns my old age to a sepulchre. [Enter Montague and others.] PRlNCE Come, Montague; for thou art early up,
MONTAGUE Alas, my liege, my wife is dead to-night; Grief of my son's exile hath stopp'd her breath: What further woe conspires against mine age?
MONTAGUE O thou untaught! what manners is in this, To press before thy father to a grave? PRlNCE Seal up the mouth of outrage for a while, Till we can clear these ambiguities,
Betroth'd, and would have married her perforce, To County Paris:--then comes she to me, And with wild looks, bid me devise some means To rid her from this second marriage, Or in my cell there would she kill herself.
Be sacrific'd, some hour before his time, Unto the rigour of severest law. PRlNCE We still have known thee for a holy man.-- Where's Romeo's man? what can he say in this?
BALTHASAR I brought my master news of Juliet's death; And then in post he came from Mantua To this same place, to this same monument. This letter he early bid me give his father; And threaten'd me with death, going in the vault,
BOY He came with flowers to strew his lady's grave; And bid me stand aloof, and so I did:
Anon comes one with light to ope the tomb; And by-and-by my master drew on him; And then I ran away to call the watch. PRlNCE This letter doth make good the friar's words,
CAPULET O brother Montague, give me thy hand: This is my daughter's jointure, for no more Can I demand.
MONTAGUE But I can give thee more: For I will raise her statue in pure gold; That while Verona by that name is known, There shall no figure at such rate be set

>
So here's my solution for problem 4.6, the CS215. It's hopefully quite a readable code, at the slight expense of running time. I'll take it over here while
And the next function we have is the read graph function which reads the graph from the IMDB files supplied on the Udacity website. The movie names are not necessarily unique, so we have changed this slightly from a previous example in a lecture to append the year to the movie name, so we get a unique string for each movie. Also, we keep track of the actors and movies we've come across so far in a dictionary to allow for this media processing later.
(Laughter) I was afraid of womanhood. Not that I'm not afraid now, but I've learned to pretend.
Back in the '50s and '60s, when I was growing up, little girls were supposed to be kind and thoughtful and pretty and gentle and soft, and we were supposed to fit into roles that were sort of shadowy -- really not quite clear what we were supposed to be.
(Laughter) There were plenty of role models all around us. We had our mothers, our aunts, our cousins, our sisters, and of course, the ever-present media bombarding us with images and words, telling us how to be.
Now when we're young, we don't always know. We know there are rules out there, but we don't always know -- we don't perform them right, even though we are imprinted at birth with these things, and we're told what the most important color in the world is. We're told what shape we're supposed to be in.
-- and how to behave. Now the rules that I'm talking about are constantly being monitored by the culture. We're being corrected, and the primary policemen are women, because we are the carriers of the tradition.
(Laughter) We don't know what's going on half the time, so it puts us in a very tenuous position.
(Laughter) Now if you don't like these rules, and many of us don't -- I know I didn't, and I still don't, even though I follow them half the time, not quite aware that I'm following them -- what better way than to change them [than] with humor?
Humor relies on the traditions of a society. It takes what we know, and it twists it. It takes the codes of behavior and the codes of dress, and it makes it unexpected, and that's what elicits a laugh.
-- try to bring my family together with laughter. It didn't work. My parents got divorced, and my sister was arrested.
"Well, why don't I do something? I always loved political cartoons, so why don't I do something with the content of my cartoons to make people think about the stupid rules that we're following as well as laugh?" Now my perspective is a particularly -- (Laughter)
(Applause)
Let's do a bunch more of these addition problems. So let's say I have 9,367 plus 2,459. So we can do this the exact same way we've done in the last few videos.
1 plus 4 is 5. And 5 plus 1 is 6. And there's nothing to carry.
3-- we have nothing to carry, so we just have the three 100,000's plus zero 100,000's. Well, that's just 300,000. And then finally, we're in the millions place.
1 plus 9 is 10. Plus eight is 18. Write the 8, carry the 1.
Now we're in the 1,000,000's place. 1,000,000 plus 5,000,000 is 6,000,000. Plus 6,000,000 is 12,000,000.
10,000,000 plus 10,000,000. This is one 10,000,000 plus another one 10,000,000. That's 1 plus 1 is 2.
15,999,001 plus 6,888,999 is 22,888,000. So you just saw, we're just doing 7 and 8 digit number additions, but you could apply this-- if I had a number with 100 digits in it, you could do the exact same thing. You just have to start at the right, go each column by each column, and then if you end up with a two-digit answer when you add the two one-digit numbers, you just carry the 10's place.
We're on problem 14. And it asks us what is the solution to the inequality x minus 5 is greater than 14? Well, to do this, this is just like solving any equality or equation.
What we do to one side, we have to do the other side.
And we want to get rid of this minus 5, and the best way to get rid of a minus 5 is to add 5, so lets add 5 to both sides of this equation.
So 5 plus and then a plus 5.
And then a 5 plus a minus 5, that's 0.
That's why we added the 5 in the first place.
So we're just left with an x on that side.
We get x is greater than 14 plus 5, which is 19.
That's choice B.
Problem 15.
The lengths of the sides of a triangle are-- so we have a triangle.
They tell us the lengths of the sides are y, y plus 1, and 7 centimeters. They also tell us the perimeter is 56 centimeters. The perimeter is equal to 56 centimeters.
What is the value of y?
So the perimeter of any shape is just the sum of the sides.
So y plus y plus 1 plus 7.
That's the distance around the triangle. And that is equal to the perimeter, which is equal to 56.
Let's see, we get y plus y is 2y, plus 1 plus 7 is 8, is equal to 56, so you get 2y is equal to what is that?
So if we subtract 8 from both sides of this equation, on the
left-hand side, we just get 2y.
On the right-hand side, 56 minus 8, that's 48.
Divide both sides by 2 and you get y is equal to 24.
And that is choice A.
Problem 16.
Now what do they want us to do?
All right, I think this is one I should copy and paste.
OK, now they're telling us-- let me pick a good color. Which number serves as a counterexample to the statement below?
So, a counterexample, an example that shows that this isn't always true. So the statement is all positive integers are divisible by 2 or 3. So we just have to find a positive integer that is not divisible by 2 or 3, by neither 2 nor 3.
Once I understand who my archetypes or persona is, the next thing I want to figure out is how do I get them in to this funnel. Regardless of whether it's web or mobile, I need to somehow figure out how to get the interest of my customer archetypes--Dave in the major urban area or Sally in the Midwest or someone in China or India. How do I get them interested, and there are two types of ways to create demand.
A standard elevator in a mid-rise building can hold a maximum weight of 1 and 1/2 tons. Assuming an average adult weight of 160 pounds, what is the maximum number of adults who could safely ride the elevator? So what we need to do is we have to get the maximum weight that the elevator could hold in terms of pounds.
Let's see if we can tackle a slightly more difficult hyperbola graphing problem. Let's add the hyperbola. Make this up on the fly x minus 1 squared over 16 minus y plus 1 squared over 4 is equal to 1.
So let's do the positive 1/2. So that means for every 2 you run over, so if you go positive in the positive x direction 2, you move up 1. So you go to the right 2 and up 1.
Looks something like that, and then we draw it from this point to that point.
And then the other asymptote is going to have a minus 1/2 slope. Remember this is our center 1 minus 1, so if I go down 1 and over.
And then just to continue it in the other direction I want to make the lines overlap. It's going to look something like that. So we've drawn our asymptotes for this function, and now we have to figure out if it's going to be a vertical hyperbola or a horizontal hyperbola.
The asymptote is this thing, but we're always going to be slightly below it. So that tells us that were always going to be slightly below the asymptote on the positive square root, and we're always going to be slightly above the asymptote on the negative square root. Because it's going to be little less, and it's negative.
So when y is equal to negative 1, you're just left with-- x minus 1 squared over 16 is equal to 1. I just canceled out this term, because I'm saying what happens when y is equal to negative 1. You multiply both sides by 16.
No, minus 3, because x minus 1 could be minus 4.
If you have the minus 4 situation, then x is equal to minus 3. You go 1 2 3 minus 3, minus 1. So those are both points on this hyperbola.
This feeling 'I am,' itself, it's like a cocktail between pure being and thought; a bridge between matter and spirit, the feeling 'I am.'
Nisargadatta Maharaj, he used it this way, he says, 'The I am is like a door,' - he says, no? - 'that swings one way towards the whole of manifestation, and the other way to infinity.'
So I'm going to talk about work; specifically, why people can't seem to get work done at work, which is a problem we all kind of have. But let's sort of start at the beginning. So, we have companies and non-profits and charities and all these groups that have employees or volunteers of some sort.
Why is that? Why is that happening? And what you find out is, if you dig a little bit deeper, you find out that people -- this is what happens:
"If I can't see the person, how do I know they're working?" which is ridiculous, but that's one of the excuses that managers give. And I'm one of these managers. I understand.
"I can't let someone work at home. They'll watch TV, or do this other thing." It turns out those aren't the things that are distracting,
A baby's T-shirt requires 4/5 yards of fabric, or 4/5 of a yard of fabric. How many T-shirts can be made from 48 yards? So what we want to do is we essentially want to say how many groups of 4/5 of a yard can we make with 48 yards?
Well after many years working in trade and economics, four years ago, I found myself working on the front lines of human vulnerability. And I found myself in the places where people are fighting every day to survive and can't even obtain a meal.
But what I'd like to talk about today is the fact that this morning, about a billion people on Earth -- or one out of every seven -- woke up and didn't even know how to fill this cup. One out of every seven people. First, I'll ask you:
"To a hungry man, a piece of bread is the face of God." Others worry about peace and security, stability in the world. We saw the food riots in 2008, after what I call the silent tsunami of hunger swept the globe when food prices doubled overnight.
And I thought, there's nothing more haunting than the cry of a child that cannot be returned with food -- the most fundamental expectation of every human being. And it was at that moment that I just was filled with the challenge and the outrage that actually we know how to fix this problem. This isn't one of those rare diseases that we don't have the solution for.
Lancet compiled all the research and put forward the compelling evidence that if a child in its first thousand days -- from conception to two years old -- does not have adequate nutrition, the damage is irreversible. Their brains and bodies will be stunted.
And here you see a brain scan of two children -- one who had adequate nutrition, another, neglected and who was deeply malnourished. And we can see brain volumes up to 40 percent less in these children. And in this slide you see the neurons and the synapses of the brain don't form.
But in Niger, for example, less than seven percent of the children are breastfed for the first six months of life, exclusively. In Mauritania, less than three percent.
It costs less than 25 cents a day to change a kid's life. But what is most amazing is the effect on girls. In countries where girls don't go to school and you offer a meal to girls in school, we see enrollment rates about 50 percent girls and boys.
Or if they get an extra ration of food at the end of the week -- it costs about 50 cents -- will keep a girl in school, and they'll give birth to a healthier child, because the malnutrition is sent generation to generation. We know that there's boom and bust cycles of hunger. We know this.
I'd like to talk about what I call our warehouses for hope. Cameroon, northern Cameroon, boom and bust cycles of hunger every year for decades. Food aid coming in every year when people are starving during the lean seasons.
Amartya Sen won his Nobel Prize for saying, "Guess what, famines happen in the presence of food because people have no ability to buy it." We certainly saw that in 2008. We're seeing that now in the Horn of Africa where food prices are up 240 percent in some areas over last year.
And the fact that France has put food at the center of the G20 is really important. Because food is one issue that cannot be solved person by person, nation by nation. We have to stand together.
WFP's been able to leave 30 nations because they have transformed the face of hunger in their nations. What I would like to offer here is a challenge.
I believe we're living at a time in human history where it's just simply unacceptable that children wake up and don't know where to find a cup of food. Not only that, transforming hunger is an opportunity, but I think we have to change our mindsets. I am so honored to be here with some of the world's top innovators and thinkers.

 Jamir is training for a race and is running laps around a field.
We have the equation -16= (x/4) + 2 and we need to solve for X.
So we really just need to isolate the X variable on one side of this equation; and the best way to do that is first to isolate it -- isolate this whole X/4 term from all the other terms.
(Music) On a typical day at school, endless hours are spent learning the answers to questions.
Sorry for starting the presentation with a cough. I think I still have a little bit of a bug going around. But now I want to continue with the 45-45-90 triangles.
For reasons that I don't really understand, lots of really important statistics start with the letter M. Today's statistics have been brought to you by the letter M. Here are some of the statistics. Maximum is the largest value in L, minimum is the smallest value in L, the midpoint is the average of the max and the min--sort of the halfway point between the largest value and the smallest value.
The mean is the average of the values in L--we all say mean sometimes or average sometimes also expected value--basically it means the same thing. The mode is the most common value in L if there's repeat. The median is say the middlest number, the middlest value in L--basically the numbers are that half the numbers are bigger and half the numbers are smaller and that there can be ties, so we'll have to be a little bit careful how we define that.
What is going to be the future of learning? I do have a plan, but in order for me to tell you what that plan is, I need to tell you a little story, which kind of sets the stage.
The Victorians were great engineers. They engineered a system that was so robust that it's still with us today, continuously producing identical people for a machine that no longer exists. The empire is gone, so what are we doing with that design that produces these identical people, and what are we going to do next if we ever are going to do anything else with it?
(Laughter) What did the poor do wrong? I made a hole in the boundary wall of the slum next to my office, and stuck a computer inside it just to see what would happen if I gave a computer to children who never would have one, didn't know any English, didn't know what the Internet was.
(Laughter) They said, "Why have you put it there?" I said, "Just like that."
"We want a faster processor and a better mouse."
(Laughter) So I said, "How on Earth do you know all this?" And they said something very interesting to me.
"You've given us a machine that works only in English, so we had to teach ourselves English in order to use it." (Laughter) That's the first time, as a teacher, that I had heard the word "teach ourselves" said so casually. Here's a short glimpse from those years.
And finally a girl explaining in Marathi what it is, and said, "There's a processor inside." So I started publishing. I published everywhere.
(Laughter) They did that, and watch a little bit of this. Computer:
Sugata Mitra: The reason I ended with the face of this young lady over there is because I suspect many of you know her. She has now joined a call center in Hyderabad and may have tortured you about your credit card bills in a very clear English accent.
(Laughter)
"And anyway, I am going away."
(Laughter) So I left them for a couple of months. They'd got a zero.
'Well, wow, I mean, how did you do that? What's the next page? Gosh, when I was your age, I could have never done that.'
Kallikuppam had caught up with my control school in New Delhi, a rich private school with a trained biotechnology teacher. When I saw that graph I knew there is a way to level the playing field. Here's Kallikuppam.
At 12. So what are jobs going to be like? Well, we know what they're like today.
"Shhh." Okay? Watch this.

"What are those twinkling lights?" They built the first curriculum, but we've lost sight of those wondrous questions. We've brought it down to the tangent of an angle.
"If a meteorite was coming to hit the Earth, how would you figure out if it was going to or not?" And if he says, "Well, what? how?" you say, "There's a magic word. It's called the tangent of an angle," and leave him alone.
"When did the world begin? How will it end?" — to nine-year-olds. This one is about what happens to the air we breathe.

Wow.

Welcome to my presentation on equivalent fractions. So equivalent fractions are essentially what they sound like They're two fractions that although they use different numbers, they actually represent the same thing.
Well if we look at these two pictures, we can see that I've eaten the same amount of the pie. So these fractions are the same thing.
pieces in the pie, then I have to eat twice as many pieces to eat the same amount of pie. Let's do some more examples of equivalent fractions and hopefully it'll hit the point home. Let me erase this.
Let me use the regular mouse.
OK, good. Sorry for that. So let's say I had the fraction 3/5.
Oh boy, this thing is messing up. And that's how we got 21/35. So it's interesting.
Now we have to introduce some extra constraints so that this truth assignment has to be satisfied. And to do that, we're going to introduce a set of nodes for each clause that is sometimes referred to as a gadget. These gadgets come up a lot in NP-completeness proofs.
This last step is growing customers for the web/mobile channels. Now if you remember we started here on the left. We didn't earn and paid media.
Seems intuitively obvious but what you want to make sure is the amount of money you're collecting over here is bigger than the customer acquisition cost to remember the amount of money you're spending from here to here. That was the customer acquisition cost, CAC, here. So lifetime value needs to be greater than customer acquisition cost.

I'm going to speak today about the relationship between science and human values.
Now, it's generally understood that questions of morality -- questions of good and evil and right and wrong -- are questions about which science officially has no opinion. It's thought that science can help us get what we value, but it can never tell us what we ought to value. And, consequently, most people -- I think most people probably here -- think that science will never answer the most important questions in human life: questions like, "What is worth living for?"
Even if you get your values from religion, even if you think that good and evil ultimately relate to conditions after death -- either to an eternity of happiness with God or an eternity of suffering in hell -- you are still concerned about consciousness and its changes. And to say that such changes can persist after death is itself a factual claim, which, of course, may or may not be true. Now, to speak about the conditions of well-being in this life, for human beings, we know that there is a continuum of such facts.
Now, of course our situation in the world can be understood at many levels -- from the level of the genome on up to the level of economic systems and political arrangements. But if we're going to talk about human well-being we are, of necessity, talking about the human brain. Because we know that our experience of the world and of ourselves within it is realized in the brain -- whatever happens after death.
And so therefore whatever cultural variation there is in how human beings flourish can, at least in principle, be understood in the context of a maturing science of the mind -- neuroscience, psychology, etc.
So, what I'm arguing is that value's reduced to facts -- to facts about the conscious experience of conscious beings. And we can therefore visualize a space of possible changes in the experience of these beings. And I think of this as kind of a moral landscape, with peaks and valleys that correspond to differences in the well-being of conscious creatures, both personal and collective.
lest we spoil the child -- this is in Proverbs 13 and 20, and I believe, 23. But we can ask the obvious question: Is it a good idea, generally speaking, to subject children to pain and violence and public humiliation as a way of encouraging healthy emotional development and good behavior?
(Laughter) Is there any doubt that this question has an answer, and that it matters? Now, many of you might worry that the notion of well-being is truly undefined, and seemingly perpetually open to be re-construed.
What are the chances that represents a peak of human flourishing?
Now, to say this is not to say that we have got the perfect solution in our own society. For instance, this is what it's like to go to a newsstand almost anywhere in the civilized world. Now, granted, for many men it may require a degree in philosophy to see something wrong with these images.
"Is this the perfect expression of psychological balance with respect to variables like youth and beauty and women's bodies?" I mean, is this the optimal environment in which to raise our children? OK, so perhaps there's some place on the spectrum between these two extremes that represents a place of better balance.
look at this situation and say, "Well, there's nothing for the Dalai Lama to be really right about -- really right about -- or for Ted Bundy to be really wrong about that admits of a real argument that potentially falls within the purview of science. He likes chocolate, he likes vanilla. There's nothing that one should be able to say to the other that should persuade the other."
(Applause) So, this, I think, is what the world needs now. It needs people like ourselves to admit that there are right and wrong answers to questions of human flourishing, and morality relates to that domain of facts.
"No, you know, this is a celebration of female specialness, it helps build that and it's a result of the fact that" -- and this is arguably a sophisticated psychological view -- "that male lust is not to be trusted." I mean, can you engage in a conversation with that kind of woman without seeming kind of cultural imperialist?

You don't understand.
For us, kissing is as important as any part.
Yeah, right!
You serious?
Oh, yeah.
- Everything is in that first kiss. - Absolutely. For us, kissing's an opening act..
like the comedian you have to sit through.. before Pink Floyd comes out.
And it's not that we don't like the comedian. It's just that that's not why we bought the ticket.
The problem is, no matter how great the show was.. you girls are looking for the comedian again.
We're in the car, fighting traffic, just trying to stay awake.
Word of advice: Bring back the comedian.
Or next time you'll find yourself listening to that album alone.
Are we still talking about sex?
The One With the Sonogram at the End
No, it's good. It is good.
It's just that Doesn't she seem a little angry?
Well, she has issues.
Does she?
Try to live with "Mr. I'm Evolving."
He's out while she's home getting the mastodon smell out of the carpet.
Marsha, see, these are cave people.
Okay, they have issues like:
"Gee, that glacier's getting kind of close."
Speaking of issues, isn't that your ex-wife? - No. - Yes, it is.
Okay. Yes, it is. I'll catch up with you in the Ice Age.
- Can I stay?
- No.
- Hi.
- Hi.
- Is this a bad time?
- No, it's.. the Stone Age.
You look great. I hate that.
Sorry. Thanks. You look good too.
Well, you know, in here, anyone who.. stands erect..
- What's new?
Still a - A lesbian?
You never know. How's the family? - Marty's still totally paranoid.
- I'm pregnant.
- Pregnant.
She didn't leave in such a hurry after all.
This is the Three's Company episode with a misunderstanding.
Then I've already seen this one.
Are you through with that?
Sorry, the swallowing slowed me down.
Whose ball of paper is this?
Mine. I wrote a note to myself, then I didn't need it.
So I balled it up and now I wish I was dead.
She already fluffed that pillow. You already fluffed It's fine.
I just don't wanna give them any more ammunition.
Parents can be cruel about the flatness of a child's pillow.
Relax, you do this every time. The place looks great.
You got a lasagna here that looks good enough.. to avoid touching.
Monica? Hi!
Monica, you're scaring me.
I mean, you're all chaotic and twirly, you know?
Not in a good way.
Calm down. You don't see Ross getting twirly every time they come.
That's because my parents think Ross can do no wrong.
You see, he's "The Prince."
They had some big ceremony before I was born.
- What? - Ugly Naked Guy got a ThighMaster.
- Has anybody seen my engagement ring? - It's beautiful.
Oh, God! Oh, God! Oh, God!
No, don't touch that.
Like I wasn't dreading tomorrow enough, having to give it back.
"Hi, Barry, remember me? I'm the girl that stomped on your heart."
Now I must return the ring without the ring.. which makes it so much harder.
Easy, we'll find it.
Won't we?
Look, it's gonna be okay. You'll give it back..
- and we'll eat ice cream. - Okay. It's a pear-shaped diamond
Any diamond ring we find, we'll run it by you.
- When did you have it last? - Doy, right before she lost it.
You don't get a lot of "doy" these days.
I know I had it this morning.
I know I had it when I was in the kitchen with
Dinah?
- Oh, don't be mad. - You didn't.
- Oh, I'm sorry.
- I gave you one job!
But look how straight those noodles are.
That's not how you look for an engagement ring in a lasagna.
I just can't do it.
Boys? We're going in.
Hi.
- That is not a happy "hi."
- Carol's pregnant.
I found it!
What?
Yeah.
Do that for two hours, you might be where I am about now.
That puts that whole pillow thing in perspective.
How do you fit into this whole thing?
Carol and Susan want me to be involved.
But if I'm not comfortable with it, I don't have to be involved.
- It's totally up to me. - She is so great. I miss her.
- What does she mean by "involved"? - Your job is done.
And the most enjoyable.
Phoebe, say something. They want me to go down to this sonogram thing.. with them tomorrow.
Remember when life was simpler.. and she was just a lesbian?
Those were the days.
- What are you gonna do? - I have no idea.
No matter what I do, I'm still gonna be a father.
This is still ruined, right?
Martha Lugwin's daughter is gonna call you.
- What's that curry taste? - Curry.
I think they're great. I really do.
The big Lugwin had a thing for you.
- They all had a thing for him. - Oh, Mom.
Why is this girl going to call me?
She just graduated, and she wants to be something in cooking or food..
I told her you have a restaurant
- I don't have, I work in a restaurant. - They don't have to know that.
- Ross, help me with the spaghetti. - Yes.
Oh, we're having spaghetti.
That's easy.
We were going to have lasagna.
- I love lasagna. - We're not having it.
Then why bring it up? He latches on.
This will sound unbelievably selfish.. but did you plan to bring up the baby/lesbian thing?
That Rachel. We saw her parents at the club.
They were not playing well.
I won't say what they spent.. but $40,000 is a lot for a wedding.
At least she had the chance to leave a man at the altar.
- What's that supposed to mean? - Nothing.
- It's an expression. - No, it's not. Don't listen to her.
Even when you were a chubby kid.. and you had no friends, you were just fine.
You'd read alone in your room. Your puzzles..
People like Ross need to shoot for the stars. With his museum and his published papers.
Others are satisfied with staying where they are.
These people never get cancer.
They're happy with what they have, content..
like cows.
Cows, Dad?
She knows how much I love cows.
I read about women trying to have it all, and I thank God.. our "Harmonica" doesn't have that problem.
- I'm telling you, you'll be fine. - Thank you, Daddy.
Oh, so this does work.
So, Ross, what's going on with you?
Any stories? No news, no little anecdotes to share with the folks?
Look, I realize you guys have been wondering.. what exactly happened between Carol and me.
And so, well, here's the deal.
Carol's a lesbian.
She lives with a woman named Susan.
She's pregnant with my child.
She and Susan are going to raise the baby.
And you knew about this?
Folks are really that bad?
Well, you know, these people are pros.
They know what they do.
They take their time. They get the job done.
They say that you can't change your parents.
Boy, if you could, I'd want yours.
Must pee.
It's worse when you're twins.
- You're a twin? - We don't speak.
She's this high-powered, driven, career-type.
- What does she do? - She's a waitress.
- Identical? - People say we look alike.
But I don't see it.
You guys, I kind of gotta clean up now.
Chandler, as an only child, you don't have this.
No, although I did have an imaginary friend.. who my parents preferred.
Hit the lights, please.
How long was I in there?
- I'm just cleaning up. - Oh, you need any help?
Okay, sure. Thanks.
Anyway..
So you nervous about Barry tomorrow?
A little.
A lot.
So, got any advice?
You know, as someone who's recently been dumped.
You may wanna steer clear of the word "dumped."
Chances are he's gonna be this broken shell of a man.
You should try not to look too terrific. I know it'll be hard.
Or I'll go down there, and I'll give Barry back his ring.
And you can go with Carol and Susan to the ob-gyn.
You've got Carol tomorrow.
- When did it get so complicated? - Got me.
- Remember being in high school? - Yeah.
Didn't you think you'd meet someone.. fall in love, and that'd be it?
- Ross? - Yes. Yes.
Man, I never thought I'd be here.
Me neither.
Sorry I'm late. I got stuck at work.
There was this big dinosaur thing.
Hi.
- You remember Susan.
- How could I forget?
Hello, Susan. Good shake, good shake.
So, we're just waiting for?
- Dr. Oberman.
- And is he?
- She.
- Of course, "she."
Is she familiar with our special situation?
- Yes, and she's very supportive.
- Okay, that's great.
No, I'm Oh.
Thanks.
That opens my cervix.
- Barry?
- Come on in.
- Are you sure? - It's fine.
Robbie's gonna be here for hours.
So, how are you doing?
I'm..
I'm okay.
- You look great. - Yeah, well.
Dr. Farber, Jason Greenspan's gagging.
Be right there. Be back in a second.
I dumped him.
So, how's this all gonna work?
The baby grows in a special place inside
Thank you.
I mean, how's this gonna work, you know, with us?
When important decisions have to be made?
- Give me a "for instance." - Well, I don't know. - How about with the baby's name?
If it's a boy. Minnie, if it's a girl.
As in "Mouse"?
As in my grandmother.
Still, you say "Minnie," you hear "Mouse."
How about..?
How about Julia?
- Julia. - We agreed on Minnie.
We agreed we'd spend our lives together.
Things change. Roll with the punches.
I believe Julia's on the table?
Sorry about that.
So, what have you been up to?
Oh, not much.
- I got a job.
- That's great.
Why are you so tan?
I went to Aruba.
Oh, no. You went on our honeymoon alone?
No.
I went with..
- Now, this may hurt. - Me?
No.
I went with Mindy.
Mindy?
My maid of honor, Mindy?
Yeah, we're kind of a thing now.
You got plugs!
Careful. They haven't quite taken yet.
And you got lenses.
You hate sticking your finger in your eye.
Not for her.
Listen, I really wanted to thank you.
Okay.
A month ago, I wanted to hurt you more than I've ever wanted to.
And I'm an orthodontist.
You know, you were right. I thought we were happy.
We weren't happy.
But with Mindy.. now I'm happy.
- Spit. - What?
Me.
Anyway..
I guess this belongs to you. Or maybe some day Mindy.
Like she'd settle for that.
Yeah, that's true.
But I think it's a nice ring.. and thank you for giving it to me.
Thank you for giving it back.
Hello!
- Please, what's wrong with Helen? - Helen Geller?
- I don't think so. - It's not gonna be Helen Geller.
- Thank you. - No, I mean, it's not Geller.
It'll be Helen Willick?
No, actually, we talked about Helen Willick Bunch.
Wait a minute. Why is she in the title?
It's my baby too.
Really? I don't remember you making any sperm.
And we all know what a challenge that is.
- You two, stop it. - She gets a credit. I'm in there too.
Helen Willick Bunch Geller? I think that borders on child abuse.
Of course not.
I'm suggesting Geller Willick Bunch.
See what he does? He knows no one's gonna say all those names.
They'll call her Geller.
My way? You think this is my way?
Of all the ways I ever imagined this moment being.. this is not my You know what?
This is too hard.
Knock, knock.
How are we? Any nausea?
- A little.
- Just a little.
I was wondering about the mother-to-be, but thanks for sharing.
- Lie back. - You know what?
I'm gonna go.
I don't think I can be involved in this family thing.
- Oh, my God! - Look at that. I know.
Well, isn't that amazing?
What are we supposed to be seeing here?
I don't know, but I think it's about to attack the Enterprise.
If you tilt your head and relax your eyes.. it kind of looks like an old potato.
Then don't do that, all right?
Monica, what do you think?
- Are you welling up? - No.
- You are. You're welling up. - I'm not.
- You're gonna be an aunt. - Oh, shut up.
Hi, Mindy. Hi, it's Rachel.
Yeah, I'm fine. I saw Barry today.
Yeah, he told me. No, it's okay. Really, it's okay.
And, Min, you know, if everything works out.. and you guys get married and have kids..
I hope they have his hairline and your nose!
That was a cheap shot, but I feel so much better now!

That didn't come out right.
2 to the negative third power is equal to 1/8. Let's do another one. Let's say 3 to the -2 power.
1/3 squared, well, that's equal to 1/9. Let's do some more problems. What if I had 2/3 to the negative third power?
The 2/3 I flipped, and I turned the -3 into a +3. And now this just becomes a Level one exponent. This equals 3/2 x 3/2 x 3/2, and that equals 27/8.
2/3 to the -3 is equal to 27/8. Let's do some more. Let's do 4/7 to the -1.
Once again, we take the reciprocal of 2, and we say 1/2 and now that can be raised to the 5th power, and that equals 1/2 x 1/2 x 1/2 x 1/2 x 1/2, and that equals 1/32. Another way we could have viewed 2 to the negative 5th is that, 2 to the negative 5th, we could have said that equals 1/2 to the 5th.
Two ways to do it, pretty much just changing the order of when you flip versus when you actually calculate the exponent. Let me do two or three more problems. And after I write down each of these problems, you might just want to pause it and see if you can do the problem yourself, and then compare your answer to mine.
1 x 1 x 1 is 1.
4 x 4 is 16 x 4 is 64. So it equals -1/64. Let's do another problem.
In lecture, we introduced a centrality algorithm that measures centrality by taking the average distance from a node to all the other nodes that it can reach. We want you to modify this algorithm to return the maximum distance from a node to all the other nodes it can reach. This algorithm captures a different notion of centrality.
Alright. So, this actually isn't too much code.
So first, what we do is run weaponJSON through JSON.parse and then store the return JavaScript object into parsedJSON. From there, we print out to the console parsedJSON frames chaingun_impact.png spriteSourceSize finally, the x data field.
We're asked to move the orange dot to -0.6 on the number line So the point, the dot, right now is at zero... and let's see this is -2, this is positive 2. So, each of these big slashes looks like it's 1
-2 This right over here would be -0.5. So we are going to go a little bit more negative than -0.5.
Up to this point in the unit, we've been talking about very, very structured graphs, very clean and organized graphs--things like chains or rings or grids, hypercubes-- that have a great deal of structure, and they look very different from the kids of actual social network graphs that you see in the wild. Regular graphs tend to have little bits of clustering in them and some people who are more sparsely connected to some other cluster, and they start to look a little bit more randomly generated or at least not generated according to a very simple, straightforward rule. It's worthwhile to think about some different ways of randomly generating graphs.
Welcome to the presentation on units. Let's get started. So if I were to ask you, or if I were to say, I have traveled 0.05 kilometers-- some people say KlL-ometers or kil-O-meters.
centimeters have I traveled? That's question mark centimeters. So before we break into the math, it's important to just know what these prefixes centi and kilo mean.
Well, 0.05 times 1,000 is equal to 50, right? I just multiplied 0.05 times 1,000. And with the units, I now have kilometers times meters over kilometers.
To go from 1/10 to 1/1,000, you have to decrease in size by 100. So we could just say 422 decigrams times 100 milligrams per decigram. And then the decigrams will cancel out, and I'll get 422
times 100, 42,200 milligrams. Now, another way you could have done it is the way we just did that last problem. We could say 422 decigrams, we could convert that to grams.
So we could say times 1 decigram is equal to how many grams? Well, 1 decigram is equal to-- no, sorry. 1 gram is equal to how many decigrams?
42.2 times 1,000. Hopefully, that doesn't confuse you too much. The important thing is to always take a step back and really visualize and think about, should I be getting a
Look at the two thermometers below. Identify which is Celsius and which is Fahrenheit, and then label the boiling and freezing points of water on each.
And the easy way to tell that you're dealing with the Celsius scale is on the Celsius scale, 0 degrees is freezing of water at standard temperature and pressure, and 100 degrees is the boiling point of water at standard temperature and pressure. Now, on the Fahrenheit scale, which is used mainly in the
 Hi. I'm Jeff, and I'm a consumer experience specialist at Google.
For this problem, we are going to look at the relationships between different kinds of graphs. We want to know if x is a subset of y, or y is a subset of x, or both, or neither. We select this first option if every star graph is also a tree graph.
In this video I wanna give you the basics of Trigonometry. It's sounds like a very complicated topic but you're gonna see this is just the study of the ratios of sides of Triangles. The "Trig" part of "Trigonometry" literally means
Let's go back and take a look at this again. We now know how deep. It's log n.
All right, so now we're in a good position to define the set p of polynomial time decidable problems. So this is a set, this includes a bunch of problems, a problem is in the set if there's an algorithm for that problem such as that when inputs size n, the running time for solving that problem is in big O then to the k for some constant k. So there has to be some kind of polynomial upper bound of an algorithm to solve that problem for the problem to be in p.
The second question asked, what is the maximum number of edges in B. We wrote a constructed graph with a maximum of edges, and take each node and connect it to everything that we can. This first node, I can only connect to the three other nodes on the right side.
I started to translate TEDTalks after seeing William Kamkwamba's talk about how to fulfill your dreams.
I wrote them, saying that these talks should have subtitles for the Deaf, and also translations for people from other countries.
[M. Pagel] Just as wings opened up the sphere of air for birds to exploit, language opened up the sphere of cooperation for humans to exploit.
Alright, so let's take a look at another piece of code: now this is another bit of the game we'll be building, but there are a few errors here, that we've added in. Your job is to go through this code, find the errors that were introduced, and then fix them based on the syntax you learned previously.
The Internet gives us the freedom, to talk with friends, make art, start a business or speak out against our governments, all on an unprecedented scale. This isn't a coincidence. The Internet's design came out of open inclusive discussions by a global community of scientists and engineers, so there was no pressure from above to lock it down.
But now a government controlled international body is making a play to become the new place where the Internet's future gets decided. It's called the International Telecommunication Union (or ITU). And in December the worlds governments will meet, to decide whether to expand its mandate to making important decisions about the net.
The ITU could pose a risk to freedom of expression on-line everywhere. Here's why. First the basics.
But now let's meet the ITU! First the ITU is old. Really old.
>> Now, the second step of parsing our map involves loading all the tileset data described in the file. For each tileset, we need to create a new image, set a call back function for once it's loaded, and then set the source value to the tilesets image attribute. This is the same basic image loading process that we've been using previously.
Welcome to this review of the installation procedure for the Haas UMC-750 Before we begin, walk around and visually inspect the machine In the unlikely event that the machine was damaged during shipping you will need to document this with a digital camera, and inform the customer
The bracket will be removed after the Z-axis has been moved to home position after startup Move to the rear of the machine and remove the Y-axis shipping bracket connecting the ram to the saddle casting Next, remove the two X-axis shipping blocks holding the ram in place in the X-axis direction
Using WD-40 or another ph-neutral degreaser spray all waycovers and other non-painted surfaces that have been coated with Cosmoline
letting the WD-40 soak-in while performing other tasks This will ease the removal of the Cosmoline
Use a plastic scraper to remove particularly thick applications of Cosmoline Do not use Scotchbrite or metal scrapers, as these will scratch the waycovers None of the axes should be moved until the Cosmoline has been removed

To break the tuber of Sexuality (Vishay) In this current era of Kaliyug (the time cycle characterized by lack of unity in thought, speech and acts) this disease is most definitely very big.
And the fact that you got married... implies that there must be so much illusionary attachment (moh), that is the reason you got married to begin with, right? Otherwise, wouldn't you have renounced worldly life (diksha) through Lord Mahavir and gone to Moksha (liberation). So, there must be so much moh that this crowd, these worldly interactions have come together for us.
45 mins for this and 45 mins for that. If you have only one hour then half an hour for this and half hour for kashays. Gradually, once we get more time, then more mistakes will get cleaned.
Wherever any form of the faults of vishay may have occurred may I recall each and every fault and heartily repent a lot and clean out all these faults entirely.
May the tuber of vishay break from its root, and for that please grant me the energy to do this type of introspection
[I surrender] my mind-speech-body All the illusory attachments associated with my name Bhaav Karma (charge karmas)
Let's learn a little bit about just how a plain vanilla bank works. So let's say that I'm an entrepreneur and I see a problem out there in the world. You have all of these hardworking people
-- whatever they do-- doctors, lawyers, engineers, construction workers-- whatever they might do. They work, they provide services to each other and they have savings, right? So right now, they're just-- whatever.
We have 11 ounces plus 29 ounces plus 5 pounds is equal to how many pounds, or blank pounds? So we need to add these three quantities right here, and they want us to give the answer in pounds. And we can only add quantities that have the same units.
40/16. It's really 40 times 1 over 16, but the 1 doesn't change anything. And then 40/16 pounds.
2 goes into 5 2 times.
2 times 2 is 4. Subtract. You have a remainder, 1.
2 goes into 10 5 times.
5 times 2 is 10. And we have no remainder. So this is exactly 2.5, which makes sense.
This first part right here simplified down to 5/2 pounds, or 2.5 pounds. So the problem becomes 2.5 pounds plus 5 pounds.
And 2.5 plus 5, fairly straightforward, it's 7.5. So this is equal to 7.5 pounds.
7.5 pounds is our answer, and we're done.
And what's cool about this algorithm is it finds the Top K elements in no particular order in Θ(n) independent of K. Now remember, the best that we could do for the previous algorithm is if K is large we ended up using sorting which is n log n. This is always Θ(n) or at least expected top running time.
0, 1, 2, 3, 4, 5, 6, 7, 8. It's in position 8. So why is it in position 8?
Not 82. Yes 28. Yes 33.
Good job. Now, as we noted before, loading an image is comprised of three steps. We actually declare a new image object, then, we specify the function to be called when the image has been loaded and finally, we set the source of the image itself.
18 minutes is an absolutely brutal time limit, so I'm going to dive straight in, right at the point where I get this thing to work. Here we go. I'm going to talk about five different things.
(Laughter) Now, there is one argument that some people do think really is that strong, and here it is. People worry about overpopulation; they say,
"Well, if we fix aging, no one's going to die to speak of, or at least the death toll is going to be much lower, only from crossing St. Giles carelessly. And therefore, we're not going to be able to have many kids, and kids are really important to most people." And that's true.
I decided to give this a little name, which is "longevity escape velocity."
(Laughter) Well, it seems to get the point across. So, these trajectories here are basically how we would expect people to live, in terms of remaining life expectancy, as measured by their health, for given ages that they were at the time that these therapies arrive.
15 years from the robust mouse. The public's perception will probably be somewhat better than that. The public tends to underestimate how difficult scientific things are.
"Let's go and periodically repair all of these various types of damage -- not necessarily repair them completely, but repair them quite a lot, so that we keep the level of damage down below the threshold that must exist, that causes it to be pathogenic." We know that this threshold exists, because we don't get age-related diseases until we're in middle age, even though the damage has been accumulating since before we were born. Why do I say that we're in range?
In this lesson, you learned about estimating population parameters with confidence intervals and then analyzing whether or not a search and treatment may have had an effect. So the examples we've used so far are the Bieber tweeter, we wanted to see it's influence on klout scores. And then the other treatment was the song about hypothesis testing for lesson nine, which I seriously might do.
And who is the practicer also? If truth already is, then who is the practicer? You have to find out.
Who is seeking? I say it is yourself in your self portrait as a person. The idea we have of who we are that is very tightly believed in, is still consciousness, it is consciousness.
PROBLEM: "The function f(x) is graphed. Find f(-1)."
Just as a note, one of the interesting things about getting customers is-- I happen to draw the funnel that says awareness, interest, consideration, and purchase, but here's just a heads up. In your funnel, in your physical channel, you might decide the steps are slightly different.
For this problem, we're going to start off with a template for a recursively generated graph. What the template says, if we want one node, we just return a single node. For other values make a G1 and a G2 that are half the size and then we make login connections between G1 and G2 by picking a random point and connecting it with a random node, another random node and connecting it with a random node et cetera and then return.
What I want to do in the next few videos is try to see what happens to a line integral, either a line integral over a scalar field or a vector field, but what happens that line integral when we change the direction of our path? So let's say, when I say change direction, let's say that I have some curve C that looks something like this.
So my challenge to you is what if you didn't have to do anything about anything at all. Nothing at all to do, nothing at all to do about anything! Yes, make a cup of tea because that doesn't give you any trouble, whatever it is that you have to do: answer the phone, make this appointment, whatever ... but that's not accompanied by this idea that that there is something that I need to do to be stable in the Awareness, because I tell you that is a trap!
Probably a lot of you know the story of the two salesmen who went down to Africa in the 1900s. They were sent down to find if there was any opportunity for selling shoes, and they wrote telegrams back to Manchester. And one of them wrote,
(Laughter) Now, there's a similar situation in the classical music world, because there are some people who think that classical music is dying. And there are some of us who think you ain't seen nothing yet.
Before we start, I need to do two things. One is I want to remind you of what a seven-year-old child sounds like when he plays the piano. Maybe you have this child at home.
He sounds something like this. (Music) (Music ends)
(Music) (Music ends) He practices for another year and takes lessons -- he's nine.
(Music) (Music ends) Then he practices for another year and takes lessons -- now he's 10.
(Music) (Music ends) At that point, they usually give up.
(Laughter) (Applause) Now, if you'd waited for one more year, you would have heard this.
(Music) (Music ends) Now, what happened was not maybe what you thought, which is, he suddenly became passionate, engaged, involved, got a new teacher, he hit puberty, or whatever it is.
(Music) And the second, with an impulse every other note.
(Music) You can see it by looking at my head.
(Laughter) The nine-year-old put an impulse on every four notes.
(Music) The 10-year-old, on every eight notes.
(Music) And the 11-year-old, one impulse on the whole phrase.
(Music) I don't know how we got into this position.
(Laughter) I didn't say, "I'm going to move my shoulder over, move my body." No, the music pushed me over, which is why I call it one-buttock playing.
(Music)
It can be the other buttock. (Music) You know, a gentleman was once watching a presentation I was doing, when I was working with a young pianist.
I went back and I transformed my entire company into a one-buttock company." (Laughter) Now, the other thing I wanted to do is to tell you about you.
The people who don't mind classical music. (Laughter) You know, you've come home from a long day, and you take a glass of wine, and you put your feet up.
A little Vivaldi in the background doesn't do any harm. That's the second group. Now comes the third group: people who never listen to classical music.
-- and maybe a little bit of a march from "Aida" when you come into the hall. But otherwise, you never hear it. That's probably the largest group.
Actually, I hear a lot, "My husband is tone-deaf." (Laughter) Actually, you cannot be tone-deaf.
Of course, I'm not sure they'll be up to it." (Laughter) All right.
(Music) Do you know what I think probably happened here? When I started, you thought, "How beautiful that sounds."
(Music) "I don't think we should go to the same place for our summer holidays next year."
(Laughter) It's funny, isn't it? It's funny how those thoughts kind of waft into your head.
And of course -- (Applause) Of course, if the piece is long and you've had a long day, you might actually drift off. Then your companion will dig you in the ribs and say, "Wake up!
Did anybody think while I was playing, "Why is he using so many impulses?" If I'd done this with my head you certainly would have thought it.
(Music) (Music ends) And for the rest of your life, every time you hear classical music, you'll always be able to know if you hear those impulses.
And it does, doesn't it? (Laughter) Composers know that.
If they want sad music, they just play those two notes. (Music) But basically, it's just a B, with four sads.
(Laughter) Now, it goes down to A. Now to G.
Oh, the TED choir. (Laughter) And you notice nobody is tone-deaf, right?
The critics sitting in the back row there, they have to have an opinion, so they say, "Hamlet is a procrastinator." Or they say, "Hamlet has an Oedipus complex." No, otherwise the play would be over, stupid.
I tell my students, "If you have a deceptive cadence, raise your eyebrows, and everybody will know." (Laughter) (Applause) Right.
It's the same gesture he makes when he comes home after a long day, turns off the key in his car and says, "Aah, I'm home." Because we all know where home is.
And what you're going to see is one-buttock playing. (Laughter) Because for me, to join the B to the E,
(Music) (Music ends) (Applause)
And one of them said, "Because we were listening." (Laughter) Think of it.
1,600 people, busy people, involved in all sorts of different things, listening, understanding and being moved by a piece by Chopin. Now, that is something.
And one of them came to me the next morning and he said, "You know, I've never listened to classical music in my life, but when you played that shopping piece ..." (Laughter) He said, "My brother was shot last year and I didn't cry for him.
If you thought, "Everybody loves classical music -- they just haven't found out about it yet." See, these are totally different worlds. Now, I had an amazing experience.
My picture appears on the front of the CD -- (Laughter) But the conductor doesn't make a sound. He depends, for his power, on his ability to make other people powerful.
People in my orchestra said, "Ben, what happened?" That's what happened.
You could light up a village with this guy's eyes. (Laughter) Right.
And she told me this, she said, "We were in the train going to Auschwitz, and I looked down and saw my brother's shoes were missing. I said, 'Why are you so stupid, can't you keep your things together for goodness' sake?'"
(Applause) Shining eyes. (Applause)
Moanin' Low, my sweet man I love him so though he's mean as can be He's the kind of man needs a kind of woman like me a woman like me... a woman like me... a woman like me... a woman like me... a woman like me... a woman like me... (etc...)
Rick wants to hire me! He's at a new studio. Where is it?
When? I don't remember what year... there's no year... How do you know there's a year for that?
- but that's what they say. And Ayodhya is in the state of Uttar Pradesh. It's right there!
Oh, because Ram's father had 4 wives. -3 wives. 3 wives?
-4 sons. 4 sons, 3 wives. OK.
-I saw a play... -Vaidehi. Vaidehi, I saw a play called Vaidehi, right, which I learned was another name for Sita.
"You have one Boon. Anything you ask of me I will do." and so she went and asked him to send Ram away for 14 years thinking that was a long enough time, that if you go away for 14 years, you're pretty much out of sight, out of mind.
Rama my son, today I wish to crown you King of Ayodhya but my evil scheming wife Kaikeyi- Grrr...
-just reminded me of an ancient vow I made. To honor this vow, instead of crowning you king, I must banish you to the forest for 14 years! Goodbye, dear boy.
He didn't create any problems, he didn't say, "why?" He just said,
"If that is your wish Father, I shall go." And then he went. And Sita said, "If you go, I go."
I hate to think what might have been if we had never met Why should I suppose that this could be? The weary days, the lonely nights, are easy to forget since I am here, and you are here with me.
Here we are, you and I Let the World just hurry by Even while I waited, somehow, dear, I knew you'd find me, and I'd find you
That's all!
Welcome to our programming tutorials on Khan Academy. Are you completely new to computer programming? Well, don't worry--that means that you're like 99.5% of the world.
What name do we give the relationship between the value proposition and the customer segment?
A thermometer in a science lab displays the temperature in both Celsius and Fahrenheit. If the mercury in the thermometer rises to 56 degrees Fahrenheit, what is the corresponding Celsius temperature? So right from the get go, there's a formula that if you get have the Celsius temperature, it'll give you the Fahrenheit, if you have the Fahrenheit, it'll give you the Celsius.

We've been focusing a lot on change overseas, and one of the things that Valerie Amos talked about was the importance of World Humanitarian Day as not just something that's happening for people overseas but it's also people making changes in their own communities right here in New York, or Los Angeles, or in Iowa or anywhere around the world that they may be.
And that's one of the things that UN is really trying to hope to encourage people to do, is to try to look in their own community, that a lot people don't have obviously the resources to travel somewhere far away, but they can look in their communities and that's how real change happens.
- [Cooper] Hey, nice to meet you. So, um that's you mic.
I took my camera and I started photographing some people on the streets with their permission, and I wanted to speak with them.
- [Cooper] So, when you hear about World Humanitarian Day what do you think? Why did you wanna be here, a part of it?
- [Dinan] I'm honored to be here. I wanted to be here just because I think something needs to happen, just around the world locally and globally.
- [Cooper] Thank you. Thank you so much.
- [Cooper] Do you have a website?
- [Dinan] I do, it's onesandwichatatime.com
- [Cooper] Alright, cool, you got a crowd you might as well get out the website. [I Was Here - World Humanitarian Day August 19 whd-iwashere.org]
It turns out we made this pretty easy. The first three—cost-based pricing, value-based pricing, or volume-based pricing— are all examples of fixed pricing tactics. That just means that the last three—yield management, real-time, and auctions— are examples of dynamic pricing.
Many people have portraits of their husband That's true, and this was found in the villa of Livia, who was Augustus' wive
Most people now have just a photograph of their husband in their home, not a full-scal marble sculpture! --Not usually But that was exactly what Livia had
On the 4th of July, 2011 we posted a request online to participate in a short film about interdependence. Artwork and videos emerged from around the world. Here is what unfolded...
We're on problem 66. And it says what is x squared minus 4x plus 4, divided by x squared minus 3x plus 2, reduced to lowest terms? So they probably want us to factor each of these quadratics and see if any of these terms cancel out.
So let's try to do that. So the numerator, this seems pretty easy to factor.
What two numbers when I multiply them equal 4?
And when I add them equal minus 4?
Well it's minus 2, right?
Minus 2 and minus 2 is minus 4.
Minus 2 squared is plus 4.
So this is x minus 2 times x minus 2.
And you could test it if you don't believe it. Multiply that out. Divided by, let's see, what two numbers?
This looks factorable. They both have to be the same sign because when you multiply them you get a positive.
And they're both going to be negative, because when you add them you get a negative 3.
So let's see, minus 2 and minus 1.
Minus 2 times minus 1 is positive 2.
Minus 2 plus minus 1 is minus 3.
So x minus 2, times x minus 1.
And if we assume that x is never equal to 2, because that would make this expression undefined, we cancel that out.
You'll learn later that would cause a hole in the graph, because the function is undefined there.
And you're left with minus 2 over minus 1.
And that is choice A.
Problem 67.
This is good practice. They give a bunch of it. They say what is-- I'll just write it-- 12a cubed minus 20a squared over 16a squared plus 8a.
So let's just try to factor out things on the top and the bottom and see what happens.
So in the top, in the numerator-- let me switch colors-- both terms are divisible by 4 and a squared.
So let's fact out a 4a squared.
So we get 4a squared. 12 divided by 4 is a 3.
And a cubed divided by a squared is an a.
So 12a cubed divided by 4a squared is 3a.
Minus 20-- I could say plus minus 20-- but you get the idea. 20 divided by 4 is 5.
And a squared divided by a squared is just a.
And if you don't believe this, multiply it out.
4a squared times 3a is 12a cubed.
And 4a squared times minus 5 is minus 20a squared.
So it works out.
You do the denominator.
Let's see, both of these are divisible by 8a, so let's factor that out.
16 divided by 8 is 2. a squared divided by a is a.
So 16a squared divided by 8s is 2a.
And if you go the other way, 8a times 2a squared is 16a squared.
So it all works out. Plus 1. 8a times 1 is 8a.
So let's see what we could do here.
This is becomes a 1.
This becomes a 2.
And a squared divided by a, this becomes a 1 and this just becomes just an a.
And we're left with a times 3a minus 5, over 2 times 2a plus 1.
And let's see.
That is choice D.
I thought maybe they'd want us to re-multiply this out again.
But that is choice D.
Problem 68.
Oh this is a good one.
I'll just write it.
They want us to multiply something.
So they say 7z squared plus 7z-- all of that-- over 4z plus 8. Times z squared minus 4-- all of that-- over z to the third plus 2z squared plus z equals.
So you must be like oh my god, I have to multiply all of these things and I have to divide them.
But the best thing, I'm guessing, is to just factor these out and all sorts of things will start canceling out with each other.
And it will turn into a pretty simple problem. Let's see, both of these terms are divisible by 7z. So le'ts factor that out.
8 divided by 4 is 2 times-- so we can definitely factor out a z here, so we get z times z squared plus 2z plus 1. I think we're almost done. Now we have to factor this.
This z plus 1 cancels out with one of these z plus 1's. I'll do the one that's written messier. And let's see, this z cancels out with this z.
We have the numerator is equal to 2x squared minus 3x plus 10x. So that's plus 7x minus 15. All of that over 3x squared.
And minus 15x plus 2x. That's minus 13x minus 10. And that is choice D.
Next problem.
Problem 70. Boy, they they want us to keep this up. This is good practice.
In the last hyperbola video I didn't get a chance to do some concrete examples. So I'll do that right now. So, let's say I had the hyperbola y squared over 4 minus x squared over, I don't know, let me think of a good number.
Square root of 4 over square root of 9, times x. So, these are the asymptotes. There's two lines here.
Let's make that my y axis. Make that the x axis. Let me switch some colors, just to make things interesting.
Negativity for the Institution, its head or its members Let's do a samayik Right now, let us do one on...
[Interferences] related to people, that why do they give this to Dimplebhai to handle? Why are they doing this? Why are you using your intellect to interfere?
All our mahatmas are said to be "Gnani Mahatmas", they are said to be Mahatmas who have attained right view-vision-belief (samkitdhaari) No matter what their behavior during discharge is, they are separate from their discharge. They are alert in their inner intent and have the right to go to moksha in one- two-three lives.
When I was a child, I always wanted to be a superhero. I wanted to save the world and make everyone happy. But I knew that I'd need superpowers to make my dreams come true.
In addition to theorizing on evolution in "The Origin of Species," Charles Darwin also wrote the facial feedback response theory. His theory states that the act of smiling itself actually makes us feel better, rather than smiling being merely a result of feeling good.
So how would you estimate the served available market or SAM for an Android Game within an order of magnitude? Choose from the list below.
All right. Now that quote's explained, why we want to use a more traditional object-oriented class base set up, let's go ahead and do that. Now, we'll be using a piece of code by John Resig that fakes class-based object oriented programming.
First, we set weapon to be Class.extend. What this means is that weapon extends all of Class's functionality, whatever that happens to be, and then adds it's own on top of it. Similarly, MachineGun is set to weapon.extend, which extends all of weapon's functionality, and then builds on top of that.
I've been intrigued by this question of whether we could evolve or develop a sixth sense -- a sense that would give us seamless access and easy access to meta-information or information that may exist somewhere that may be relevant to help us make the right decision about whatever it is that we're coming across. And some of you may argue, "Well, don't today's cell phones do that already?"
But other than letting some of you live out your fantasy of looking as cool as Tom Cruise in "Minority Report," the reason why we're really excited about this device is that it really can act as one of these sixth-sense devices that gives you relevant information about whatever is in front of you. So we see Pranav here going into the supermarket and he's shopping for some paper towels. And, as he picks up a product, the system can recognize the product that he's picking up, using either image recognition or marker technology, and give him the green light or an orange light.
Some of you may want the toilet paper with the most bleach in it rather than the most ecologically responsible choice. (Laughter) If he picks up a book in the bookstore, he can get an Amazon rating -- it gets projected right on the cover of the book.
Reading the newspaper -- it never has to be outdated. (Laughter) You can get video annotations of the events that you're reading about.
(Laughter) As you interact with someone at TED, maybe you can see a word cloud of the tags, the words that are associated with that person in their blog and personal web pages. In this case, the student is interested in cameras, etc.
My student Pranav, who's really, like I said, the genius behind this. (Applause and cheering) (Applause ends)
Thank you. (Applause)
So far we've been dealing with one way of Probability, that was the probability of (A) occur, The number of events that satisfy A over all number of the equally likely events All of the equally likely events.
Well there's 6 equally likely events, and there are three even numbers you can get Which are, two, four and six So there's three over six, or simply,
One half chance And this is a really good model of equally likely events.
So, the probability of Heads is 60% The Probability of Tails, well there're only two possibilities, whether there can be heads or tails! So if I say the probability of heads or tails, is going to be equal to 1 !
It is equal to The Probability of Getting Tails on the First flip, multiplied by the probability of getting
heads on the second flip, heads being on the second time doesn't affect the probability of heads and similarly, a tails, again, on the third flip And we know that the probability of getting a tails is 0.4 The Probability of getting a heads(on any flip) is 0.6 and the probability of getting tails on the third flip is 0.4
Or another way it to write is 9.6%, a little less than 10%. We have a 9.6% chance of getting this probability Remember, in this case, the position of heads or tails, first, second or third does not affect
Once again, Big Theta allows us to work with functions in a much simpler form without losing their essence. Let's just make sure that we understand how to do that. Let's take this expression 2n² + 6n + 20 log n.
Some of the questions you might want to be asking as you're outside the building now talking to customers is competition. Competition kind of exists outside the business model canvas. Think of the canvas now floating in a world where other people's business model canvases are floating as well.
"Well, who else is out there and what are they doing?" The next thing you want to be asking, again outside the canvas, why is this problem so hard to solve, or why is this service not being done by other people? It might be that, hopefully, you really do have an insight or breakthrough.
"in the last 3½ years who tried this, and they all failed." Warning: You might want to investigate why that happened.
In the star network the description is that there is a center node to which all other nodes are connected using the edge. There are n-1 other nodes if you choose one center, and each is connected to the center node with one edge so there are two n-1 edges and that seems good.
As we discussed in the previous Unit, to find the most central node in a social network, it's useful to be able to take each node in a graph and find out how far it is from all the other nodes in the graph to get a square for a particular node and then to repeat that operation essentially to find out the distance from every other node to every other node. Really what we want to know is the shortest distance between any pair of nodes. So all pairs we would like to know the distance--the length of the shortest path.
I'm used to thinking of the TED audience as a wonderful collection of some of the most effective, intelligent, intellectual, savvy, worldly and innovative people in the world. And I think that's true. However, I also have reason to believe that many, if not most, of you are actually tying your shoes incorrectly.
So I went back to the store and said to the owner, "I love the shoes, but I hate the laces." He took a look and said, "Oh, you're tying them wrong."
My students often ask me,
"What is sociology?" And I tell them, "It's the study of the way in which human beings are shaped by things that they don't see." And they say, "So how can I be a sociologist?
"He wants to burn Korans, our holy book. These Christians, who are these Christians? They're so evil, they're so mean -- this is what they're about."
So here. Of course, you got it wrong. You're generalizing.
What do you think about that scene?
Okay, try this. Bring it back. This is the scene here.
Okay, now follow me on this, because I'm taking a big risk here. And so I'm going to invite you to take a risk with me. These gentlemen here, they're insurgents.
Now, put yourself in their shoes.
Are they brutal killers or patriotic defenders? Which one? Can you feel their anger, their fear, their rage at what has happened in their country?
You see, that's empathy. It's also understanding. Now, you might ask,
Welcome to the presentation on using the quadratic equation. So the quadratic equation, it sounds like something very complicated. And when you actually first see the quadratic equation, you'll say, well, not only does it sound like something complicated, but it is something complicated.
And know it goes through minus 6, because when x equals 0, f of x is equal to minus 6. So I know it goes through this point. And I know that when f of x is equal to 0, so f of x is equal to 0 along the x axis, right?
Well, that's a little -- x equals minus 2. So now, we know how to find the 0's when the the actual equation is easy to factor. But let's do a situation where the equation is actually not so easy to factor.
squared minus 9x plus 1. Well, when I look at this, even if I were to divide it by 10 I would get some fractions here. And it's very hard to imagine factoring this quadratic.
a is minus 10. Minus 10 times c, which is 1. I know this is messy, but hopefully you're understanding it.
Welcome to the presentation on level four linear equations. So, let's start doing some problems. So.
Let's have -- let me say, x plus two over x plus one is equal to, let's say, seven. So, here, instead of having just an x in the denominator, we have a whole x plus one in the denominator. But we're going to do it the same way.
And we're done. And if you wanted to check it, you could just take that x equals negative five / six and put it back in the original question to confirm that it worked. Let's do another one.
I'm making these up on the fly, so I apologize. Let me think. three times x plus five is equal to eight times x plus two. Well, we do the same thing here.
Negative one / five. On the left-hand side we have x. And on the right-hand side we have negative thirty-four / five.
In the last video we introduced ourselves to the law of supply and it was a fairly common sense idea that if we hold all else equal, that if the price of something goes up, there's more incentive for more producers to produce it, or a given producer to produce more of it. And we saw that. As the price goes up, we moved along the supply curve, and the quantity produced went up.
I'll call this the "price of inputs."
Or, another way to think about it is the "cost of production." So if the price of inputs, maybe the price of labor, the people who would have to pick the grapes, or our fuel that we need to transport the grapes, or the land, if any of that increased, then at a given price point, we would make less money. There's less incentive for us to do it, especially if this is true . only for grapes
Maybe we'll say, "Okay, if it's now more expensive to get grape seeds, maybe I'll start planting something else, because I'm not getting as much profit per pound of grape." So if the price of my inputs, or if the size of my costs go up, at any given price point,
So, maybe I'm a farmer, and I know very little bit about farming, so I don't even know if this is possible, but maybe on my land, I'm saying, "Well, some of my land is going to be for grapes, and some of it is going to be for blueberries."
And so what would happen if the price of a related good -- in particular, blueberries -- what would happen if the price of blueberries went up?
Well, if the price of blueberries went up, then I would say, "Wow, you know, maybe I can do better with blueberries," and I would allocate more of my land to blueberries than to grapes. And so, once again, if the price of related goods... well, it depends which related goods... but if the price of productive substitutes, so the price of other things I could produce... if the price of other things
This is really just a way to think about things. "Hey, obviously, if I can make more money off of blueberries, now, all of a sudden, I'm going to allocate more of my land to blueberries than to grapes."
Now let's think about what happens with the number of suppliers. "Number of Suppliers." And this one is... this is pretty common sense: the more people that are supplying, the higher the supply would be.
The price of inputs might go down, so that would make your supply go up. Or, you could just say, There's just going to be more grapes popping off of these new types of vines that we got so we're just going to produce more grapes."
And then the last one I'll cover, and it's a little bit strange in the grape analogy, is the "expected future prices."
So the expected future prices -- price expectations. And let's go away from the grapes, because grapes are perishable goods, they go bad.
But if we're talking about something like oil, you would say, "Hey, why should I pump all of the fixed amount of oil in the ground today to sell it at today's lower prices. I'm going to lower the supply today so I can sell it in the future."
-- and that's.. .
I'm just going to emphasize by writing the word "current" -- current supply will go down so you can hoard it to sell it in the future.
Now, you see we have a parseJSON function that takes a string of JSON in, and then we're going to parse it using the JSON.parse method that is included in and accessible in just about any modern browser. JSON.parse takes this string,
Weapon.JSON in and will return a JavaScript object representing the JSON that it's parsed. Now, once we've done that what I want you to do is grab a specific piece of data, from that JSON. Let's say you want to grab data from the JavaScript object returned from JSON.parse and let's say you put that JavaScript object into the variable "parsed".
We were able to look at the documentation and see that context.drawlmage allowed us to pass in the image object as well as the position on the canvas we'd like to draw, 192 by 192. Before we move on let's cover an important topic about canvas drawing, coordinate systems.
Cholera was reported in Haiti for the first time in over 50 years last October. There was no way to predict how far it would spread through water supplies and how bad the situation would get.
Can you speak about Karma Yoga as a way
to purify strong Vasanas?
such as projections and judgements of others ...yes.
First, again this is something that can be brought directly into the Inquiry... ...these Vasanas, and I don't know if everybody is used terms like 'Vasana' but just to quickly say what it implies only...some deep tendancies, ... recurring tendancies that are so strong and full of identity. When you speak about the strength of any tendancy it's only because it has a lot of identity in it. No identity - no strength.
Initially all thoughts, they are equal in weightlessness. When you believe in them, then it empowers them... it gives them weight.
I said before...a thought without belief has no power. A thought with belief can start a war, even. So belief is the thing - not thought.
Say, I don't mind if this Vasana ...this energy ...these tendancies destroy the body...I don't care, but I'm staying only as the Presence Itself. Then gradually you'll see that each time it comes the Presence doesn't move away to make room for these. Then, at a certain point, they are there together.
"he's still counting money". But inside he's not counting anything. Just this movement is going on.
"you've got this type of personality", you won't know what it means. But the mind doesn't give up. Unchallenged its still there.
(laughter) So this is one way of dealing with it. Gradually, even the impression of these Vasanas, they will not follow you any more.
Because that is here. Then you must come to your own 'Para-Braham' means your Original Truth. Then Maya has no hold on you.
We're on problem 53. It says Toni is solving this equation by completing the square. ax squared plus bx plus c is equal to 0, where a is greater than 0. So this is just a traditional quadratic right here.
All right, four steps to derive the quadratic formula are shown below. I said in previous videos that you can derive the quadratic formula by completing the square. And we actually do that in another video.
That's choice A.
Problem 55. Which of the solutions-- OK, I'll put all of the choices down.
So which is one of the solutions to the equation? So immediately when you see all of the choices, they have these square roots and all that. This isn't something that you would factor.
Bx plus C is equal to 0. The quadratic equation is minus b. Well they do it lowercase.
OK, they want to know the solution set to this quadratic equation. I'll just copy and paste. So that's essentially the set of the x's that satisfy this equation.
As I said we should be able to do all these pretty easy--constant time. The midpoint is the smallest number plus the biggest number divided by 2 so the average of those two.
114/2 which is 57. The median is the number in the middle of the sorted list which let's see--51. We've got one, two, three, four, five smaller and one, two, three, four, five bigger--so good.
To provide a test network for looking at shortest path problems, I downloaded from the Internet a social network, as it were, of marvel comic book characters. It's a lot like the IMDB data and that there's sort of people and they are linked together if they appear together in a sort of movie, but in the comic book world, we're talking about something more like superhero characters in which particular comic books they both appeared in. So for example, Spiderman at least in this set here, Spiderman appeared in a comic book called COC 1 and also in one called MaxSec 3 and Thor and Hulk also appeared in MaxSec 3.
Do you think that doing good theoretical analysis and doing that in conjunction with the development of algorithms leads to better, more practical systems? Yes, of course.
Do you know how many species of flowering plants there are? There are a quarter of a million -- at least those are the ones we know about -- a quarter of a million species of flowering plants. And flowers are a real bugger.
"I guess something has coevolved with this." And sure enough, there's the insect. And I mean, normally it kind of rolls it away, but in its erect form, that's what it looks like.
(Laughter) Now deceit carries on through the plant kingdom. This flower with its black dots: they might look like black dots to us, but if I tell you, to a male insect of the right species, that looks like two females who are really, really hot to trot.
(Laughter) And when the insect gets there and lands on it, dousing itself in pollen, of course, that it's going to take to another plant, if you look at the every-home-should-have-one scanning electron microscope picture, you can see that there are actually some patterning there, which is three-dimensional. So it probably even feels good for the insect, as well as looking good.
(Laughter) Here we see ylang ylang, the component of many perfumes. I actually smelt someone with some on earlier.
(Laughter) And the plant showers them with pollen, and off they go and pollinate. And what a wonderful thing it is.
Hi. Welcome back. We have had time and opportunity to do many different problems and I have taken the time to go really deep in to them and I have spent a lot of time today with you because I believe the value add in online is the explanation one on one.
Like many of you here, I am trying to contribute towards a renaissance in Africa. The question of transformation in Africa really is a question of leadership. Africa can only be transformed by enlightened leaders.
I'm stopped by two soldiers wielding AK-47 assault weapons. And they asked me to join a crowd of people that were running up and down this embankment. Why?
"Well, where are these leaders coming from? What is it about Ghana that produces leaders that are unethical or unable to solve problems?" So I went to look at what was happening in our educational system.

Currently, I'm calling my mom to ask her what I should say to Emily today.
[line ringing]
Do you have a second to talk to me? woman:
[woman laughing]
Okay. I don't know. I just think that, you know-- just concentrate on the fact that, you know, you have very, very high feelings of esteem for her, that she's somebody that you've always admired. man:
[romantic music] Uh, hello, "Life In A Day."
I'm still with Emily, and we're still hanging out in Chicago. Um, this is... We--we just came out of this place, which was cool.
man: Theresa, look at me. Theresa:
[romantic music continues] man: Well, so here's the deal. Uh, I asked her if she wanted to go on a romantic date with me sometime, and she says, "No."
"What about the possibility of a possibility?" And she said-- She said no to that. No possibility.

[laughter] So, Ann, in anticipation of your previous answer,
John says, "I suppose an occasional blow job is..." [laughter]
woman: Are you trying every possible way? I told you it won't move.

Looking at the Business Model Canvas, fill in the box where your product would go and then fill in the box where your market would go.
>> Now, we all know that you all love animated robots running around and shooting each other. I mean, after it all, it is good family friendly fun. But we also need to draw the environment map.
It's a big world out there. Billions of us trying to live, love, prosper, and make sense of our brief time on this planet. Since the dawn of humanity, we've been passing information from one person to another through a common language.
We've developed an elegant solution to both problems -- a way for you to learn a language for free, while at the same time helping to translate text from the web, enabling a wealth of
language-shackled information to be liberated for all of humanity. It's called "duolingo". Here's how it works:
Learn a language while translating the web.
I've been asked to make a video on algebraic division or algebraic long division. So I'll make a video an algebraic long division. I'm just going to make up a problem.
The x to the 1 space or the x space. The x squared space. The x to the third space.
And then 8x to the third minus 8x to the third is 0, so we can ignore that right there. And if we want, we can bring down the rest of the number, but maybe just for fun we'll bring down the next spot just like we do in traditional long division.
Because I think we might find that real estate useful. All right, I'm back. Actually, it doesn't hurt to bring down the whole thing.
So 2x goes into minus 11x squared minus 11/2 x times. So we'll write that in our x place. So minus 11/2.
I think you see what we're doing. After every step we're canceling out the largest degree of the polynomial we're dividing into. Fair enough?
This is equal to 31/4. This is the same thing as 31 over 2 times 1/2. So it's 31/4.
And now we subtract. This is a plus here. We subtract the green expression from the light blue expression and we're left with this.
The answer turns out to be none of these, but if you though ring, that was true for a little while. If you thought hypercube, that we true pretty for the same amount of time, and I actually thought the answer was hypercube until I drew out a picture and discovered that it wasn't. Here's why.
What I want to do in this video is one, just do a bunch of addition examples so that we really get some good practice and we really get warmed up with addition. And what I even more want to show you is that we now have all the tools we need to really tackle any addition problem. So let's just get warmed up with some one-digit addition problems, but these are the ones that always give me a
Two plus four is six. Not too bad.
What about nine plus three? We saw that in the last video.
Nine plus one is ten. Plus another one is eleven. Plus three is twelve.
Nine plus three is twelve. And it's probably not a bad idea. It's good to visualize what's happening here, but it's also not a bad idea to be able to do these very fast.
Six plus seven. This one I used to find difficult to remember. But six plus seven is thirteen.
Six plus seven is thirteen.
Eight plus six or six plus eight is going to be fourteen. And that's the same thing as seven plus seven -- is also going to be fourteen.
And if you think about it, we got the same number here as there. And it makes sense, right? Because we took one away from eight, but we had one more than six.
Five plus six. Well, that's eleven. Let me just do a couple of more really fast.
Two plus three is five. We didn't have to carry anything. And then in the tens place we just have this two sitting here.
Two plus nothing -- it's two tens. It's two dimes. So then we put that down there.
Two dimes and five pennies, or twenty-five cents depending -- a lot of people, money makes it easier to understand things or maybe to be motivated to understand things. All right, let's do another one.
What is thirty-eight plus seventeen? So we look at just the ones place.
What is eight plus seven? We haven't done that one yet; I'll do it up here.
Eight plus seven is equal to-- it's going to be one more than eight plus six.
Eight plus six is fourteen, then eight plus seven is going to be one more than that. So it's going to be equal to fifteen. So in this problem we write the five here.
One plus three plus one is this five.
Thirty-eight plus seventeen is fifty-five. Or five tens and five ones.
That's the same thing as fifty-five. Let's do a couple more problems. I think you'll see that we have the tools to tackle anything, any problem.
Forty-seven plus nine. We just look at the ones place.
Seven plus nine. We know what that is already. We did that problem already.
Ninety-nine plus eighty-eight. That's a hard one. And you just have to look at the parts of the problem and you'll see how it'll all work out.
Nine plus eight we know already is seventeen. That's a good one to remember.
Nine plus eight is seventeen, but it's always good to be able to visualize it as well. So nine plus eight is seventeen. Carry the one.
Ten plus eight is eighteen. Now this is interesting. We want to write eighteen down.
One plus nine plus eight is equal to eighteen. We wrote the eight down there and we say, let's carry the one. We carry the one, but we carry it into the hundreds place.
Eight plus two. We know that that is equal to ten. You can do the number line if you need to.
Eight plus two is equal to ten.
Put the zero in the ones place, carry the one. Now we're in the tens place. This is really one ten.
Seven plus seven is fourteen. So this right here is going to be equal to fourteen. Carry the one.
One plus three plus five.
Well, one plus three is four. Plus five is nine.
Four plus five is nine, so this is going to be equal to nine. Nothing to carry. We only had something in our ones place.
So four thousand, three hundred and sixty-eight plus five hundred and seventy-two is four thousand -- we'll put a comma there to make it easy to read -- four thousand, nine hundred and forty.
So, imagine you're standing on a street anywhere in America and a Japanese man comes up to you and says,
"Excuse me, what is the name of this block?" And you say, "I'm sorry, well, this is Oak Street, that's Elm Street. This is 26th, that's 27th."
"Excuse me, what is the name of this street?" They say, "Oh, well that's Block 17 and this is Block 16." And you say, "OK, but what is the name of this street?"
(Applause) In most music, we think of the "one" as the downbeat, the beginning of the musical phrase: one, two, three, four. But in West African music, the "one" is thought of as the end of the phrase,
(Laughter) There's a saying that whatever true thing you can say about India, the opposite is also true. So, let's never forget, whether at TED, or anywhere else, that whatever brilliant ideas you have or hear, that the opposite may also be true.
Now I would be remiss in talking about strategic alliances not to talk about the greatest strategic alliance ever made, and that was Steve Jobs at Apple when he built the iPod. Jobs understood that the iPod hardware was a wonderful device, but without software, iTunes, it was still just another piece of iron. But, even when they had the hardware and software ecosystem, they were still missing the content, the music, that would go on it.
So it's equal to 5 times 2 over 6 times 3, which is equal to:
5 times 2 is 10 and 6 times 3 is 18, so it's equal to 10/18. And you could view this as either 2/3 of 5/6, or 5/6 of 2/3, depending on how you want to think about it. And this is the right answer.
We just did it before we actually took the product. You could actually do it right here. So if you did it right over here, you'd say, well, look, 6 times 3 is eventually going to be the denominator.
In the video where we introduced the atom, I went off a bit about how at the center of an atom we have the nucleus, and it's actually a very small fraction of the total volume of the atom. And the electron, even though we call it a particle, it can really be best described as kind of a smear around this nucleus. That although it's a particle, because of the Heisenberg uncertainty principle, we can never tell exactly at a given moment where the particle is and what its momentum is.
And, really, just to kind of start off in case you're not familiar with it -- although, I think a lot of people have an intuitive feel for what statistics is about.
And essentially -- well in very general terms it's kind of getting your head around data. And it can broadly be classified. Well there are maybe three categories.
And this is when you use data to essentially make conclusions about things. So let's say you've sampled some data from a population -- and we'll talk a lot about samples versus populations but I think you have just a basic sense of what that is, right?
So the first thing that, I don't know, that I would want to do or I think most people would want to do when they are given a whole set of numbers in they're told to describe it. Well, maybe I can come up with some number that is most indicative of all of the numbers in that set. Or some number that represents, kind of, the central tendency
-- this is a word you'll see a lot in statistics books. The central tendency of a set of numbers.
And this is also called the average. And I'll be a little bit more exact here than I normally am with the word "average." When I talk about it in this context, it just means that the average is a number that somehow is giving us a sense of the central tendency. Or maybe a number that is most representative of a set.
geometric means and maybe we'll cover the harmonic mean one day. There's a mean, the median, and the mode. And in statistics speak, these all can kind of be representative of a data sets or population central tendency or a sample central tendency.
1 plus 1 is 2. 2 plus 2 is 4. 4 plus 3 is 7.
1, 1, 2, 3, let's add another 4 there. So now, there's no middle number, right? I mean 2 is not the middle number because there's two less than and three larger than it.
Here's one example of a possible solution for our program to create a combination lock. And this code is based on a code from Amit Gupta. So we take on a list of nodes.
The beginning of any collaboration starts with a conversation.
FN: I always had a passion for alternative vehicles. This is a land yacht racing across the desert in Nevada.
YB: Combination of windsurfing and skiing into this invention there.
FN: And I also had an interest in dangerous inventions. This is a 100,000-volt Tesla coil that I built in my bedroom, much to the dismay of my mother.
YB: To the dismay of my mother, this is dangerous teenage fashion right there.
(Laughter)
FN: And I brought this all together, this passion with alternative energy and raced a solar car across Australia -- also the U.S. and Japan.
YB: So, wind power, solar power -- we had a lot to talk about. We had a lot that got us excited.
FN: Really make a fully integrated product, something beautiful.
YB: And we made a baby.
(Laughter)
FN: Can you bring out our baby?
(Applause) This baby is fully electric. It goes 150 miles an hour.
YB: Thank you.
FN: Thank you TED. And thank you Chris, for having us.

[Beah] Yes, between 12 and 13 and then I ended up going to a military base actually looking for safety. And it was at this military base, with the Sierra Leone Armed forces, that I was actually forced to be a soldier.
Well, for me it means, I think, its just reaffirming the faith in everyone in the world, that we have a responsibility to help each other if we live in this world.

Through this course, we looked at a number of different algorithms that we were trying to solve and for each of them, we worked out what their running time was so for finding the connectivity between two nodes in an undirected, unweighted graph, the running time is the number of nodes plus the number of edges. Finding the shortest path in a weighted, undirected connected graph took time m times the logarithm of n. Removing the minimum value of a heap is log n.
And a problem can be efficiently solved obviously if it has an efficient algorithm-- that's a reasonable question to ask--well, do our problems have efficient algorithms.
I've got a square here.
What makes it a square is all of the sides are equal. I haven't gone in depth into angles yet, but these are at right angles to each other. I'll just draw it like that.
So let's say that's my same square. I'm going to draw a little bit, so let me divide it in the middle. Let me see, I have -- and we divide them again.
Q: Sir, we would like to know as much as we can about you... before we start these dialogues. Would you please tell us... where we are and who you are... and how you came to participate... with Mr. Krishnamurti in his teachings.

K: I think it all depends how serious you are. How serious in the sense... how deeply you want to go into these questions... which is after all your life.
Just as a reminder, what the teams will be starting with in Week 1 is filling out the business model canvas and getting out of the building and testing their hypotheses about the value proposition, customer segments, and channel. In the next week they'll be testing customer relationships, revenue streams, and partners. And then in Week 3 they'll be looking at key resources, key activities, and cost structure.
The goal is to get out of the building and use the canvas as a scorecard for the customer development activities that are going on in the Z axis and depth between each one of those canvas scorecards. You need to make sure your team is learning about who are those right customers, what are the right value propositions, what is the right revenue model. And it's the activity that they're doing outside the classroom.
"it's the 4 people who threw us out but said they would have paid a lot of money." "Maybe the business is over there." That's what you as mentors and you as facilitators are actually helping these teams see.
Now, once we have the ability to manipulate the canvas, the next step is figuring out how to do the right way. So, you'll find that as the number of images in your environment and the number of images in your asset set start increasing exponentially, the management of that and drawing to the screen, is actually going to get exponentially harder as well. So, in this unit, we're actually going to introduce the concept of an atlas, and talk to you about how to boil all of this complexity down into something that's usable, and easy to do.
All right. Here's our answer. Each of these areas here is a region.
N - m is -5, plus 7 is 2. Ta da!
What can happen to a startup?
One of the reasons that's most cited as to a cause or the cause of why World War One turned into a world war as opposed to just a regional conflict in Southeast Europe is the alliance system that was developing in the decades leading up to World War One. And to understand that, i've distilled a bunch of the alliances that occurred in those decades leading up to World War One. This is just a distilled version, there are many other alliances that were tangentially related, but I'll try to distill down the ones that were directly related to all of the dominoes falling in 1914, that led to all of Europe being essentially at war with each other.
France and Russia. And then finally in the early nineteen hundreds, 1904 to 1907, you have a series of agreements, "ententes" essentially means "agreements", agreements between the British Empire and France, between the British Empire and the Russian Empire, to essentially get on good terms with each other. These weren't as formally bonding that "Hey, if someone's going to attack you, i'm going to attack them", but they were essentially able to resolve a lot of their issues on what's going on in their other imperial conquest and they formed what is called "The Triple Entente", the triple agreement between

All right--so if you did this right, you would realize that what you need to do to compute an expected value the sum of the overall values that it can take on the probability of that value times the value itself. So what that amounts to is summing overall the pairs w and x that are neighbors to v. We sum whether they're either connected or they're not connected and that's represented by the c[wx] thing and we need to multiply that by the probability that we picked that particular w and x.

[Music plays] Trusting the Universe Two Minutes from Satsang with Mooji
[Questioner:] I want to say one little thing. Everybody's been talking about trusting the universe to take care of you.
Well, I never trusted the universe and it took care of me, anyway.
[Laughter] So I just ... you know ... [Mooji laughs; audience still laughing]
[Mooji:] If you say, so beautifully,
'Even if I don't trust it, it's taking care of me,' there must have been some insight to appreciate this. This is the difference. Because you are right.
It says, 'This power, like the sun, shines on everything.'
In the same way, it says, 'The rain falls on the righteous and the unrighteous, even.' Everything is there.

Something is there, taking care.
Very great.
We've all been told that the colors of the rainbow correspond to different wavelengths of visible light - red, orange, yellow, green, blue, and violet. Where's pink in that list? It's not there.
Let's take a look at an approach for actually finding shortest paths in graphs, and we'll use this example once again. It will help to actually have names for the other nodes, so I'm going to add these in. Just remember what breadth-first search does for this graph starting from A.
Three hops to G, one, two, three. Yep. There's no faster way to get to G.
Even this A to D, we don't know, there might be like a half weight path that goes from C to D, but we do know that there's going to be no faster way to get to C right because that is the shortest edge out of A. Any of the longer edges we're assuming we can't take negative weight edges that would cause this four to get smaller than the three. All we really know is that this three is the smallest.
D has edges to B, F, and E. Here's B, and here's F and E.
This path to F through D is going to add another seven for a total of 11, and this path to E through D is going to add another three for a length of seven, and remember there's also a D to B link, which would add nine to this, which would get us there in 13, and we already knew how to get there in 13, so that doesn't really change anything. Based on these three, we know the fastest way to A, C, and D, and once that we have also been able to reach, we know that E has the shortest distance, which is seven, and there isn't going to be any faster way to get to E cause there aren't any other nodes that we could get to and then get to E faster than seven. We can lock that one down, pull off the open list, add all its edges to the non-completed nodes.
From E, we can also get to G in one step, which would have been seven plus the additional step for a total of eight, and that's all we can reach from E. Looking things over, we now know that the fastest way to get to G is eight steps because the only other way we could get to G would be to visit one of the other nodes, and then go to G, and that would have to be longer than eight. We're going to lock it down, and now we pull of the open list and look at the edges out of G.
G can get to F in two steps, and that's an improvement because before the best we could get to F was 11 steps.
Now, we can get to F in ten. Can we get anywhere else new? No, cause the only nodes that are complete now are B and F, and they're already in the picture, and in fact, now we see that the fastest way to get to F is going to be in ten steps cause the only other way to get to F that we haven't considered is getting there through B, and that's going to be longer.
We can lock this down. Alright! So, let's look at F.
The distance to B is 11. Now, we've kind of lost a little bit of information of how we get to B in 11? But, we'll deal with that in a little bit.

The 1/2 is smaller than the 7/12, so it might be easier to just do this as mixed numbers so we don't have to do all of that borrowing and regrouping. So let's write both of them as mixed numbers. So we have 1 and 1/2.
12 times 7 is 84.
84 plus 7 is 91. It is 91. Did I do that right?
91. Yep, that looks right.
91/12. Now, we've written both of them as improper fractions, but we still have different denominators, so we have to have a common denominator.
So what is the least common multiple of 2 and 12, or what's the smallest number that's divisible by both of them?
Well, 12 is divisible by 12, and 12 is also divisible by 2, so 12 is the least common multiple. So we want both of them to be over 12. And this fraction already is over 12 so we don't have to change it:
6 times 30 is 180, 6 times 1 is 6, so it's going to be 186. And now we subtract. So the difference in their ages is going to be-- the denominator is going to be 12.
95, right?
6 minus 1 is 5, and then 180 minus 90 is 90, so that works out. So the way we've expressed it right now, it isn't is an improper fraction, but they want us to write it as a simplified mixed number, so let's do that.
So how many times does 12 go into 95? Let's see, 8 times 12 is 96, so that's too big, so 12 goes seven times. So this is equal to 7.
7 times 12 we know is 84 from our times tables, or you could just think it's going to be 14 plus 10 times 7, which is 70. Either way. And let's see, 95 minus 84:
So 12 goes into 95 seven times. You get 7 wholes and you have 11 left over. So 95/12 is 7 and 11/12.
Write six hundred forty-five million five hundred eighty-four thousand four hundred sixty-two in standard form. So let's tackle this piece by piece. So the first part we have six hundred and forty-five million.
So let's think about that.
But it's not just six hundred forty-five. We have six hundred forty-five millions. So we could view that as 645 times 1,000,000.
Well, I'll write it like this.
584 thousand. So let me write the thousand.
So 584 thousand. So it's 584 times 1,000. And what's that going to look like?
584, three zeroes. So that's that part. And then finally, we have four hundred sixty-two, and that's just 462, straight up.
Namaste. Salaam. Shalom.

A single postage stamp costs $0.44. How much would a roll of 1,000 stamps cost? So we're going to have 1,000 stamps, and each of them costs $0.44, so we can multiply the 1,000 stamps times $0.44 per stamp.
The most important issue to me is that we find the best President and not the one that sounds good and looks good, that he is going to be good all the way around.
It's definitely broken but I don't say, per se, that we can fix it as one, but we have to come together as a whole and fix it together. Well first that we start standing up for what we believe in and that it's not just the one person that believes in everything ...it's always more than one person, you know, never the only one.
Now one important detail we'll need to understand is how to get our image data that our artists create into our game. For example, the image file name. Also the width and height of the image, whether it's been rotated at all and various other pieces of information we might need to know.
The difference between a JavaScript object and JSON is that JSON is simply a string that we can then parse to create a java script object. And that's what we're going to do.
We're asked to identify the percent, amount, and base in this problem. And they ask us, 150 is 25% of what number? They don't ask us to solve it, but it's too tempting.
150 is 25% of what number? That number right here we're seeing is x. So that tells us that if we start with x, and if we were to take 25% of x, you could imagine, that's the same thing as multiplying it by 25%, which is the same thing as multiplying it, if you view it as a decimal, times 0.25 times x.
150 is 25% of this number. And then you can solve for x. So let's just start with this one over here.
0.25 times some number is equal to 150. Now there's two ways we can do this. We can divide both sides of this equation by 0.25, or if you recognize that four quarters make a dollar, you could say, let's multiply both sides of this equation by 4.
Six times, right? If it goes into 100 four times, then it goes into 150 six times.
6 times 0.25 is-- or actually, this is now a 25. We've shifted the decimal. This decimal is sitting right over there.
25 goes into 0 zero times.
0 times 25 is 0. Subtract. No remainder.
25 goes into 0 zero times.
0 times 25 is 0. Subtract. No remainder.
So 150 divided by 0.25 is equal to 600. And you might have been able to do that in your head, because when we were at this point in our equation, 0.25x is equal to 150, you could have just multiplied both sides of this equation times 4.
4 times 0.25 is the same thing as 4 times 1/4, which is a whole. And 4 times 150 is 600. So you would have gotten it either way.
150 is 1/4 of 600. Now let's answer their actual question. Identify the percent.
150 is 25% of the base, of 600. The important thing is how you solve this problem. The words themselves, you know, those are all really just definitions.

So, if we take a look at the Jersey² team was worrying about, it's what most start-ups worry about on day 1, is does my value prop match my customer segment, and do I have product market fit? You tend to worry about channels and customer relationships and whether I can make money. You also are worrying about market size, etc.

This actually puts us in a really interesting situation. We can build a sorting algorithm out of the pieces that we just created. This is sometimes called heap-sort.
I mentioned NP hardness before. Now that we've talked about reduction, we can revisit that definition and say-- a problem X is NP hard if we can reduce some other NP hard problem to it, what that really means is we can use a solution to problem X to solve some NP hard problem, that means that solving X has to be at least as hard as the NP hard problem making it therefore NP hard. Now, there's something sort of irritatingly circular or turtles all the way downish about this.
Loading these TlLEDmaps is actually a pretty complex process, so we're going to walk through it piece by piece. First, to parse the JSON, you'll notice that we've actually modified our load function call to call parseMapJSON with the data we get from our xhr request. Now the data we've received from the internet is actually a JSON blob.
JSON.parse, passing the JSON blob, to actually give us an object in Javascript. Next, what we'd like to do is to actually cache some of the values of this new
JSON object inside of the map class itself, so, we don't have to keep walking through and querying that data object later on. The parameters we care about keeping track of right now are the total number of tiles crossing down in the atlas. The size of each of those tiles in pixels, and then the size of the entire map in pixels.
We're on problem 1.
A project scheduled to be carried out over a single fiscal year has a budget of $12,600. Divide it into 12 equal monthly allocations. So if we divide it by 12 how much are we going to spend per month?
12,000 divided by 12 is 1,000.
600 divided by 12 is 50. So they're going to spend $1,050 per month. At the end of the fourth month of that fiscal year, the total amount actually spent on the project was 4,580.
4 times 50.
200. That's how much they should have spent after four months if they were on budget. They ended up spending 4,580.
1 is clearly an integer, so this can't be an integer, right? So we have to pick an n that is essentially not divisible into 100. So what are their choices?
Well 100 is clearly divisible by 1. You'll get an integer there. So it's not 1.
2.
100 is clearly divisible by 2.
100 divided by 2 is 50. That's not it.
3.
100 divided by 3. That's 33.333. That's not an integer.
3. Rectangular floors x and y have equal area. If floor x is 12 by 18-- let me draw that.
So floor y is 9 feet wide.
So they're saying it has the same area, so essentially they're saying that 9 times-- and they want to know its length. So let's call that l. So the area of floor y, which is 9l, is equal to the area of floor x, which is equal to 18 soon. times 12.
And I even multiply this out, because I don't know off the top of my head what 18 times 12 is, but we can just divide both sides by 9, and we get I is equal to-- let's divide the 18 by the 9.
2 times 12, which is equal to 24. And that's choice E.
Problem 4.
Each carton contains b boxes and each box contains c-- OK, so c cartons.
Carton is equal to b boxes.
And then they say a box is equal to 100 paper clips. How many paper clips are contained in 2 cases? So we could say 2 cases is equal to 2c cartons, right?
So each carton has how many boxes? Has b boxes, right? So this is going to be equal to 2 times c.
60 is not prime so that doesn't work.
61 as far as I can tell is prime. Right? I can't think of any numbers that go into it, although maybe I'm missing a few.
62 isn't prime. That's even.
63 is 9 times 7. That's not prime.
64 is 8 times 8.
65. That's not prime, divisible by 5.
66? Nope.
67.
Is 67 prime? Let's see, 67. I think it is.
68 is not prime. It's even.
69 is divisible by 3. And 70 is clearly not prime. So if I'm right, these are the two prime numbers.
17 times 3 is 51. Yes. I can't think of anything.
Question 6. you A rainstorm increased the amount of water stored in state J reservoirs from 124 billion gallons to 138 billion gallons. If the storm increased the amount of water in the reservoirs to 82% of total capacity, approximately how many billion gallons of water were the reservoirs short of total capacity prior to the storm?
So capacity is going to be equal to 138 divided by 0.82, right? Well, maybe I skipped a step. Let me write that.
So 82 goes into 138 1 time. We get 6.
13 minus 8 is 56.
560.
82 goes into 560-- Well, let's see.
80 goes into 56 6 times.
6 times 82 is 12, plus 1.
6 times 8 is 48.
49. And then we're left with, let's see. What is that?
680.
82 goes into 680 8 times.
8 times 2 is 16.
8 times 8 is 64.
65. And you're left with, I don't know, what is this?
24.
240. So after the decimal it keeps going, but the total capacity is about 168. So how short were they?
168 minus 124. So 68 minus 24 is 44 gallons. And that's choice E.
Problem 7. Actually, I'm almost of time. I'll continue this in the next video.
We're asked to write 7/8 as a decimal and as a percent. We'll start off with a decimal, and we'll see it's pretty easy to go from a decimal to a percent. Now, whenever you see a problem like this, it's sometimes confusing.
Well, 8 times 5 is 40, so it goes in nice and evenly. So it goes into it five times. 5 times 8 is 40.
You know, what I do is write for children, and I'm probably America's most widely read children's author, in fact. And I always tell people that I don't want to show up looking like a scientist. You can have me as a farmer, or in leathers, and no one has ever chose farmer.
I had a thumb, I had 85 dollars, and I ended up in San Francisco, California -- met a lover -- and back in the '80s, found it necessary to begin work on AlDS organizations. About three or four years ago, I got a phone call in the middle of the night from that teacher, Mrs. Posten, who said, "I need to see you.
I'm disappointed that we never got to know each other as adults. Could you please come to Ohio, and please bring that man that I know you have found by now. And I should mention that I have pancreatic cancer, and I'd like you to please be quick about this."
We grew up interacting with the physical objects around us. There are an enormous number of them that we use every day. Unlike most of our computing devices, these objects are much more fun to use.

The camera is actually not only understanding your hand movements, but, interestingly, is also able to understand what objects you are holding in your hand. For example, in this case, the book cover is matched with so many thousands, or maybe millions of books online, and checking out which book it is. Once it has that information, it finds out more reviews about that, or maybe New York Times has a sound overview on that, so you can actually hear, on a physical book, a review as sound.
You have to check your computer in order to do that, right? (Applause) When I'm going back, I can just use my boarding pass to check how much my flight has been delayed, because at that particular time,
(Laughter) And I think the imagination is the only limit of what you can think of when this kind of technology merges with real life. But many of you argue, actually, that all of our work is not only about physical objects.

We actually did that in general already earlier in the unit, so yeah, 4-colorability is definitely an NP. It's not necessarily an NP because the number of colors is bigger.

That's it!
We're asked to subtract. And we have the problem 68 - 42. And what I want to do here, is 1) just show you how I would do this problem, and then, talk a little bit about why it actually works.
8 - 2 is equal to 6. (Repeating: 8 - 2 = 6)
6 - 4 = 2. And since these are in the 10's place, this is really saying 60 - 40 = 20. And I'll make that a little bit clearer in a second.
So I encourage you do that in your own time after this video - verify that 42 + 26 = 68. And also verify what 68 - 26 is equal to. And you should see that is equal to 42.
Here's an example for you to take a look at. This is a graph and we're trying to get from point A to B which is often what we do in graphs, and you can see here I've actually annotated the edges of the graph with weights and we're trying to find the shortest path where the length is measured as the sum of these weights. And when you figured that out, write the length of the path in the box here.
So, we're going to change this to breadth first search, but we're going to do it really easily, at least for the people version, by grabbing the first element off the open list instead of the last element off the open list. Let's take a look at how that changes things. We start off with d as the first thing added to the list and d on the open list, and now what we do is, well the first and the last element are the same, so nothing changed yet.
One of the most common ways of dividing the world is into those who believe and those who don't -- into the religious and the atheists. And for the last decade or so, it's been quite clear what being an atheist means. There have been some very vocal atheists who've pointed out, not just that religion is wrong, but that it's ridiculous.
In the early 19th century, church attendance in Western Europe started sliding down very, very sharply, and people panicked. They asked themselves the following question. They said, where are people going to find the morality, where are they going to find guidance, and where are they going to find sources of consolation?
You know, in the 18th century in the U.K., the greatest preacher, greatest religious preacher, was a man called John Wesley, who went up and down this country delivering sermons, advising people how they could live. He delivered sermons on the duties of parents to their children and children to their parents, the duties of the rich to the poor and the poor to the rich. He was trying to tell people how they should live through the medium of sermons, the classic medium of delivery of religions.
"Hey, how about a sermon?" they'd go, "No, no. I don't need one of those. I'm an independent, individual person."
(Applause) The other thing that religions know is we're not just brains, we are also bodies. And when they teach us a lesson, they do it via the body.
(Applause) Chris Anderson: Now this is actually a courageous talk, because you're kind of setting up yourself in some ways to be ridiculed in some quarters.
Is there an equivalent process by which there's a sort of bridge between what you're talking about and what you would say to them? I would say that there are many, many gaps in secular life and these can be plugged.
"I don't believe so I can't have community, so I'm cut off from morality, so I can't go on a pilgrimage." One wants to say, "Nonsense. Why not?"
Well, one thing that we're all very suspicious of is individual leaders.

Amara makes video globally accessible with captions and translations. It was designed with three audiences in mind. First, if you are a video creator,
What we have here is a Python encoding of the breadth-first search algorithm we've been talking about for finding shortest paths in these kind of graphs. In this particular case, there are some infrastructure in the beginning for reading the data for the comic book characters from a file. The one that we're using here is tens of thousands of lines long.
"Hey, was that the neighbor the one we're actually searching for?" If it is, we can just be done. We can just return that distance for that node; otherwise, we have to proceed and we take that neighbor and we just stick it on the end bar open_list, so that we'll catch up with it later. And then we're back into the loop and it's just going to continue pulling things off the open list. assigning the distances until finally we discover the node they were looking for, or if the open list eventually goes completely empty.

So we have f of x is equal to negative x plus 4, and f of x is graphed right here on our coordinate plane. Let's try to figure out what the inverse of f is. And to figure out the inverse, what I like to do is I set y, I set the variable y, equal to f of x, or we could write that y is equal to negative x plus 4.
And negative x plus 4 is actually perpendicular to y is equal to x, so when you reflect it, you're just kind of flipping it over, but it's going to be the same line. It is its own reflection. Now, let's make sure that that actually makes sense.
Let's see, if we start at negative 1/2, if we move over to 1 in the positive direction, it will go down half. If we move over 1 again, it will go down half again. If we move back-- so it'll go like that.
We're on part B. The region R is rotated about the x-axis to form a solid. Find the volume V of the solid in terms of k. So this is our region R, and it's going to be rotated around the x-axis... it's going to be rotated around the x-axis to form a solid.
When planning an initial product, which is the most important?
The third question asked, what is the maximum possible path length in B? It's pretty straightforward to see the chains have a maximum possible path length of n-1 and this n-1 is an upper bound on the path link of any graph with n nodes and so we are checking to see if we can make B into a chain. If we can, then n-1 will be the maximum possible path link and this is about as close as we can get into making B into a chain.
For B, we get that the possible maximum path link is six edges.
We're asked to simplify 8 plus 5 times 4 minus, and then in parentheses, 6 plus 10 divided by 2 plus 44. Whenever you see some type of crazy expression like this where you have parentheses and addition and subtraction and division, you always want to keep the order of operations in mind. Let me write them down over here.
And those are these little brackets over here, or however you want to call them. Those are the parentheses right there. That gets top priority.
6 plus 10 is 16 and then divide by 2 and you would get 8. But remember: order of operations. Division takes priority over addition, so you actually want to do the division first, and we could actually write it here like this.
So 10 divided by 2 is 5, so this will result in 6, plus 10 divided by 2, is 5.
6 plus 5. Well, we still have to evaluate this parentheses, so this results-- what's 6 plus 5? Well, that's 11.
So 8 plus 20 is 28, so you can view this as 28 minus 11 plus 44.
28 minus 11-- 28 minus 10 would be 18, so this is going to be 17. It's going to be 17 plus 44. And then 17 plus 44-- I'll scroll down a little bit.
7 plus 44 would be 51, so this is going to be 61. So this is going to be equal to 61. And we're done!
Bestial happiness Every morning you prepare a meal, and then scrub the utensils thoroughly clean. And then you will even check everything
"ah this time, the utensils are sparkling, they have become clean". or you stand besides the maid (observing her) and tell her, "be sure to wash them (utensils) well." Then at night, you dirty the utensils again, and once again wash them. Then the next day morning - dirty them all again, and wash them once again!
Let's take [the topic of] bestial happiness (pashavi anand) Where have we taken pashavi anand What are the different situations where we have become happy after hurting someone? alternatively when riots breakout [we will ask] "how many from our side died?
At that time what do we [feel]... what does Dada say, "what is considered humanity? The religion of mankind?" "what if someone were to get this angry at me, then? Then, it would pinch me tremendously.
To develop such awareness is called humanity. And after getting angry, if we say, "but, we have to tell them off.
"he is swindling people of their money, He is so insulting, He is making other suffer such pain..." and in these feelings of dwesh we begin to dislike (abhav) and scornfully reject (tiraskar) the person
And then when we come to know that he has changed or has gone to jail, we feel, "yes, his behavior was such that he was headed that way!" And we become happy. The thing here is that, one experiences extreme abhorrence, and a result beastly inner intent emerges.
Or it may also be a kind of our ego to show self importance (rof), just walking around he will give the other person a couple of slaps, "Sit straight, do not sit in that way, don't do this and that!" Just to show his self importance (rof)...
Oh Dada Bhagwan,
Oh Shri Simandhar Swami Prabhu, Give me the strength to do a samayik with pure applied awareness of the Self (shuddha upyog)
And when that individual suffers any kind of loss, the pashavi anand that emerges from within. for all such mistakes, grant me the absolute energy to see these in samayik
For whichever community, I have tiraskar towards, whichever individual, I have tiraskar towards, or have tiraskar for individuals of any religion, or due to vishay - vikar (sexual impulses), due to maan (pride), or due to moha (illusionary attractions),
I have tiraskar towards any individual, and when that individual suffers any loss, the pashavi anand that emerges from within me, for all such mistakes, may I be able to wash them (mistakes) with a lot of repentance give me the strength to do such a samayik [I surrender] my mind speech and body, all the illusionary attachments associated with my name, Bhaav karma (charge karmas),
So let's take a look at the last type of market, it's the clone market. This takes foreign business models and adapts it to local conditions. What's a foreign business model--typically right now, a foreign business model is one that's occurring in the US.
In the last video, we had this rectangle, and we used a triple integral to figure out it's volume. And I know you were probably thinking, well, I could have just used my basic geometry to multiply the height times the width times the depth. And that's true because this was a constant-valued function.
It is x-- I want to make sure I don't run out of space. xyz times-- and I'm going to integrate with respect to dz first. But you could actually switch the order. Maybe we'll do that in the next video.
Once again, this is just the mass at any small differential of volume. And if we integrate with z first we said z goes from what?
The boundaries on z were 0 to 2.
The boundaries on y were 0 to 4. And the boundaries on x, x went from 0 to 3. And how do we evaluate this?
I was given the very good suggestion of making it scroll, but, unfortunately, I didn't make it scroll enough this time. So I can delete this stuff, I think. Oops, I deleted some of that.
And y goes from 0 to 4. And then we still have the outer integral to do. x goes from 0 to 3 dx. And when y is equal to 4 you get 16x.
8x squared. And you evaluate it from 0 to 3. When it's 3, 8 times 9 is 72.
Four people earn $180 for working at an after-school program. If they divide this money up equally, how much will each person receive? So we want to divide $180 into four equal groups so that each of the four people can have the same amount.
4 times 4 is equal to 16, so that goes into 18.
4 times 5 is equal to 20, so that does not go into 18, so this is going to go into 18 four times. 4 times 4 is 16, and now we subtract. We essentially find the remainder here.
40 times 4 is 160.
180 minus 160 is 20. That's why we bring down the 0. But if you just think about the process, you say, OK, what's the smallest-- if I just go with the 1, 4 doesn't go into it, so let me move on.
4 goes into that four times.
4 times 4 is 16.
Subtract from 18, you get a 2, bring down the 0. Now 4 goes into 20 how many times? Well, we just wrote it over here.
4 times 5 is equal to 20. So 4 goes into 20 five times.
5 times 4 is 20. You subtract, and you have no remainder left over. So 180 divided by 4 is equal to 45.
PROBLEM: "The perimeter of a rectangular fence measures 0.72 kilometers.
The length of the fenced area is 160 meters. What is its width?"
Let me draw it. So that is a rectangle. You can imagine we're looking from above.
So that w is in meters, So we could add it all up. So if you were to add all of these up, you would get a certain number of meters. So if you were to add all of these up, you have a w plus a w, so you would have 2w.
So let's convert this 0.72 kilometers to meters. And the way to do that, we want the kilometers in the denominator, so it cancels out with the kilometers, and you want meters in the numerator.
Now, how many meters equal a kilometer?
Well, it's 1,000 meters for every 1 kilometer. 1 kilometer is 1,000 meters. Now, if you multiply these two things, the kilometers cancel out.
The left-hand side, that cancels out. That's why we subtracted 320. And that you just leaves you with 2 times the width is equal to 720, minus 320, which is 400.
And then you're left with w = 400/2, which is 200. And we said that w was in meters. So the width is 200 meters.
My name is Marcin. I am a farmer, technologist, born in Poland, now in the US. I started a group "Open Source Ecology" and we took on a very big, hairy, audacious goal.
So the first one we'll start off with is the circle.
And you've probably seen this for many years already, but I'll review, if you don't know it already. The general form of an equation, or the general equation for a circle, is x squared plus y squared is equal to r squared, where r is the radius of the circle. And this would be a circle centered at the point 0,0.
look like this-- let me do it in a different color-- the circle would look something like-- make sure it's a circle-- well, it's supposed to be centered at 0,0, but that's close enough-- so its center will be right here, and the radius if you go from the center to any point along that circle will have a distance of r, so if you go from there to there it's r, from there to there it's r, from there to there it's r, and to some degree, this formula, all it is is an extension of the distance formula, which is really just the extension of the Pythagorean Theorem. So for example, the distance formula, if I want to know the distance between some point x,y and the point 0,0, what you do is, you take the difference of the x's-- so x minus 0-- you square that, and then you add that to the distance between the y's squared-- so that's one y point minus 0y-- y is equal to 0-- square that, and that is equal to the distance squared. So if you simplify this, x minus 0 squared, that's just x squared plus-- and this is just y squared is equal to distance squared.
CHAPTER ill. Gregor's serious wound, from which he suffered for over a month--since no one ventured to remove the apple, it remained in his flesh as a visible reminder--seemed by itself to have reminded the father that, in spite of his present unhappy and hateful appearance, Gregor was a member of the family, something one should not treat as an enemy, and that it was, on the contrary, a requirement of family duty to suppress one's aversion and to endure--nothing else, just endure. And if through his wound Gregor had now apparently lost for good his ability to move and for the time being needed many, many minutes to crawl across his room, like an aged invalid--so far as creeping up high was concerned, that was unimaginable-- nevertheless for this worsening of his condition, in his opinion, he did get completely satisfactory compensation, because every day towards evening the door to the living room, which he was in the habit of keeping a sharp eye on even one or two hours beforehand, was opened, so that he, lying down in the darkness of his room, invisible from the living room, could see the entire family at the illuminated table and listen to their conversation, to a certain extent with their common permission, a situation quite different from what had happened before.
Grete," and when Gregor was again in the darkness, while close by the women mingled their tears or, quite dry eyed, stared at the table. Gregor spent his nights and days with hardly any sleep. Sometimes he thought that the next time the door opened he would take over the family arrangements just as he had earlier.
"Perhaps the gentlemen don't like the playing? It can be stopped at once."
"On the contrary," stated the lodger in the middle, "might the young woman not come into us and play in the room here, where it is really much more comfortable and cheerful?"
"Oh, thank you," cried out the father, as if he were the one playing the violin. The men stepped back into the room and waited. Soon the father came with the music stand, the mother with the sheet music, and the sister with the violin.
"She is right in a thousand ways," said the father to himself. The mother, who was still incapable of breathing properly, began to cough numbly with her hand held up over her mouth and a manic expression in her eyes. The sister hurried over to her mother and held her forehead.
"he's already starting up again." With a fright which was totally incomprehensible to Gregor, the sister even left the mother, pushed herself away from her chair, as if she would sooner sacrifice her mother than remain in Gregor's vicinity, and rushed behind her father who, excited merely by her behaviour, also stood up and half raised his arms in front of the sister as though to protect her.
"Come and look. It's kicked the bucket. It's lying there, totally snuffed!"
The Samsa married couple sat upright in their marriage bed and had to get over their fright at the cleaning woman before they managed to grasp her message. But then Mr. and Mrs. Samsa climbed very quickly out of bed, one on either side. Mr. Samsa threw the bedspread over his shoulders, Mrs. Samsa came out only in her night-shirt, and like this they stepped into Gregor's room.
Grete, who did not take her eyes off the corpse, said, "Look how thin he was. He had eaten nothing for such a long time. The meals which came in here came out again exactly the same."
Grete went, not without looking back at the corpse, behind her parents into the bed room. The cleaning woman shut the door and opened the window wide. In spite of the early morning, the fresh air was partly tinged with warmth.

Alright, so next we're going to look at some recursively generated graphs. We start off with a set of n nodes, then we create a graph on half of the nodes recursively. We create a graph on the other half of the nodes recursively.
This one became quite famous. It's sometimes known as the Names and Boxes Problem. In this problem, there are 100 prisoners, and the warden comes and tells them that they will be given their freedom if they can win the following game:
100 boxes are going to be put on the table. In each box will be put one of the prisoner's names on a piece of paper. They'll be lined up on a table in a room, and the prisoners will be brought into the room one-by-one, and each prisoner is permitted to look in 50 boxes, trying to find his own name.
The value proposition for a company that's selling services is kind of the same. You just need to ask--what are core services that are part of your value proposition. Consulting, a haircut, investment advice, and if you're selling whether it's software or hardware, you could have separate services that are part of this whole product-- pre- and post-sales services, finding the right solution, financing, free delivery.
Fortunately, the answer is the third one. What you need to do to prove an upper bound are on the hardest of a problem is if you can find an algorithm for example that solves the problem--provably solves the problem and provably into the fourth time, then--well, we don't know if a faster algorithm exists but we know it's at least solvable in end to the fourth. So the big O or Θ that we get from that is exactly the upper bound.
Find the sum 3 1/8 + 3/4 + ( -2 1/6) Let's just do the first part first, This is pretty straightforward.
We have two positive numbers, let me draw a number line , we are going to start with 3 1/8, this is 0, then we have 1, 2, 3 and then you have 4.
3 1/8 is going to be right about there so let me just draw its absolute value 3 1/8, is going to be 3 1/8ths to the right of 0
So it is going to be exactly that distance from 0 to the right. The length of this arrow, you could view it as 3 1/8th.
Now, whenever I like to deal with fractions especially when I have different denominators i like to deal them with improper fractions, it makes the addition, and the subtraction, and actually the multiplication and divison a lot easier.
So 3 1/8 is the same thing as 8 times 3 is 24 plus one is 25 over 8.
To that we are going to add 3/4, we are going to move another 3/4
to the right, this length of this is 3/4
So plus 3/4.
Where does this put us, so both of these are positive intergers, so we can just add them, we just have to find the like denominators we have 25/8 + 3/4.
So we get 6, so 3/4 is the same thing as 6/8. So we have 25/8, and we're adding 6/8 to that, that gives us 25 plus 6 is 31, over 8.
So this number right over here is 31/8 And it makes sense, because 32/8 will be 4, so it should be a litte bit less than 4
So this number right over here is 31/8 or the length of this arrow, the absolute value of that number is 31/8.
If you want to write it as a mixed number, it would be 3 7/8. Now to that we want to add a -2 1/6.
So we're going to add a negative number. So think about what -2 1/6 is going to be like. Let me do this in a new color, do it in pink.
I guess we should say we are going to add a -1, add a -2, and then a -1/6.
So -2 1/6, we can literally draw it like this. -2 1/6, we can draw it with an arrow that looks something like that, so this is -2 1/6.
There are a couple of ways to think about it, we could just say, when you add this arrow, this thing is moving to the left. We could put it over here and you would get straight to -2 1/6.
But we're adding this -2 1/6, it is same thing as subtracting a 2 1/6; we're moving 2 1/6 to the left. And we're going to end up with a number whose absolute value is going to
This value right here, which is going to be the answer to our problem, is going to be the difference of 31/8 and 2 1/6. And it's a positive difference, because we're dealing with a positive number.
So we just take 31/8, and from that, we will subtract 2 1/6. So this orange value is going to be 31/8 minus 2 1/6. So 2 1/6 is the same thing as 6 times 2 is 12 plus 1 is 13.
3 minus 2 is 1, 9 minus 5 is 4. So it is 41/24, positive. You can see that here, just by looking at the number line.
This right here is 41/24, and it should be a little bit less than 2, because 2 would be 48/24.
My cousin Nadia is taking a summer calculus course and she called me last night. And she had some limit problems and they were excellent problem. So I thought it was worthwhile to make videos on the problems that she had to figure out.
And what is this? This has the form a squared minus b squared, right? So that's going to be-- But a squared-- If this is a squared minus b squared, a would be z squared, right?
Is 8. And then 2 plus 2 is 4. 6 over 12 is equal to 1/2.
Clear image. Invert colors. So it was the limit as x approaches 0 of cotangent of 2x.
So cosecant of x. That's just 1 over sine. I remember that by saying it's not intuitive.
And we have a problem here still. Because when you take x approaches 0, this term right here goes to 0 and we have a 0 in the denominator, which is just not acceptable. Because it's undefined.
Right. Because really, this is just-- We haven't even done any manipulation yet. This is the same thing as this.
Cosine of 0 is 1, right? So cosine of 2 times 0, which is 0, that's also 1. So that is equal to 1 over-- right, cosine of 0 is 1 --over 2 times 1.
Now there is a new market and here, the customers are really unknown. All you have is a vision and a set of hypothesis, and what you're hoping is you're going to provide for customers is something transformational--not just incremental improvement but transformational improvement. And the good news is and bad news is that there are no competitors on day 1--it's pretty lonely.
An example--Groupon. Groupon single handedly created the daily deals market.
So let's see if we understand the types of partners and suppliers that are available and remember, none of these come with a memo that says they look exactly like these. Some of these might actually blur the lines, but let's take a look and see if we can understand who would fit under strategic alliances, joint ventures, traffic partners, coopetition, joint business development, and suppliers. Match the type of relationship with each of these partnership examples.
The order is customer discovery, customer validation, customer creation and company building.
>> And so here's that code in practice, the first thing we do is loop through each of the tileSets images, checking the firstgid against the tilelndex. Once we find the correct one, we'll break out knowing that i is the proper index. Once we find this, we can set the pkt.img value to equal the image of the atlas, and then we go through and do a little bit of math to determine what the tile offset is.
localldx. From there, we can do a little simple math, given the localldx and the numXTiles horizontally for this atlas to give us to give us our x and y indexes. Once we have the indexes, we can multiply them by the tileSize to give us our px and py.
Let's say we are operating... ...in three dimensions. And I have a function, rho, ...which is a function of (x,y,z)... ...and it gives us the mass density... ...at any point in three dimensions, ...of some fluid. Some particular fluid.
Let me use the same color... ...that I used for v before.
And there's a couple of ways you could conceptualize this, ...so you could view this as... Obviously it maintains the direction of the velocity, ...but now its magnitude... One way to think about it is... ...kind of the momentum density.
"How much do they go together?" And since n is a unit vector, ...since it has a magnitude 1, ...it's-- this is essentially saying..
"What is..."
"What is the magnitude... ...of the component of f... ...that's going in the direction of n?" Or the component-- Or...
"What is the magnitude of the... ...component of f that is... ...normal to the surface?" Or "How much of f is normal... ...to the surface?" So the component of f that is... ...normal to the surface... ...might look something like... ...might look something... ...like that.
"How much mass, given this mass density, ...this velocity, is going directly... ...out of this little dS, ...this little... ...'infinitesimally' chunk of surface... ...in a given amount of time?" And then if we were to add up... ...all of the dS-es, ...and this is what essentially that surface integral is, ...we're essentially saying,
"How much mass, ...in kilograms per second, ...that's what we picked... How much mass... ...is traveling across this surface... ...at any given moment in time?" And this is really the same idea we do with... ...the line integrals.
And this isn't like... ...some crazy, abstract thing. I mean, you could imagine... You know, you could imagine... ...something like water vapor in your bathroom.
Customer relationships is kind of a fourth piece, and customer relationship has a really interesting interaction with these other three pieces. It basically says how do I get customers, how do I keep them, and how do I grow them, and just like thinking about distribution channels, these are very different for web mobile than they are for physical channels. But visually, they kind of look like this double-sided funnel.
Multiply 6 times 1/4. Simplify your answer and write it as a mixed number. So let's just do the multiplication.
6 divided by 1 is 6.
6 ones is 6. Depending how you think about it, this is exactly the same thing as 6. So we just rewrote our whole number as a fraction.
10 is the same thing as 10/1. So this become 6/1 times 1/4, and then we just multiply the fraction. We multiply the numerators, so this is equal to 6 times 1 as our numerator.
1 times 2 is 2. You subtract. You have a remainder of 1.
So this is 1 and 1/2. So that's our right answer. We've just simplified the answer and wrote it is a mixed number or we could simplify it at this stage.
3 times 1 is 3.
1 times 2 is 2, so it's 3/2. And you do this exact same process. You say that 3/2 is the same thing as 1 and 1/2.
This right here is 4/4. This right here is 4 over 4, which is equal to a 1, so this is equal to 1. And then this right here is two 1/4's, or this right here is 2/4.
2 out of 4 is the same thing as 1/2, so this right here is one out of a possible one, and then two. So this is 1 and 1/2, which is exactly what we got before.

 Welcome to the presentation on age word problems. Let's get started.
So that is equal to Ali's age in 4 years. Let's read what other information there is in the problem. It says, in 4 years.
We'll say Naz for short.
And let's say this is Omama. And this is today. I'm making a little chart.
"Gary Yourofsky: Fighter for justice"
"‏4 anti-fur activists arrested"
"Animal rights activist vows to live and die for his cause"
"Animals Are Slaves To The Circus"
"Activist stages protest outside circus"
"Driven by a passion for justice"
"Taking a stand and standing alone"
"Activist chained to car at Shrine Circus"
"Yourofsky chained to car at fur store"
"Animal rights activist won't stand for cruelty"
"Champion or criminal?" "Activists disrupt fur store business"
"Activist devotes life to animal rights"
"I'm prepared to go to prison"
Breaking laws, from Jesus Christ to Nelson Mandela, from Rosa Parks to Martin Luther King,
laws have always been broken to facilitate substantive change.
Today's speaker holds a BA in journalism from Oakland University and a radio broadcasting degree from Specs Howard School of Broadcast Arts.
Gary Yourofsky has already experienced more than many people will ever want to in a lifetime.
He has been arrested more than ten times, and spent 77 days in a maximum security detention center, all in the name of animal rights. Gary has lectured in hundreds of schools nationwide, including The University of Connecticut, Michigan State and Bowling Green, Author Charlotte Montgomery even included a chapter about Gary in her book, Blood Relations.
There is not an asterisk next to that commandment saying: "unless you walk on all four and have fur, feathers, horns, beaks or gills." You can keep your friends, your politics and you patriotism, still watch your favorite TV shows and listen to your favorite music, even if it's Ted Nugent. I'll be making some sarcastic, yet truthful comments throughout the speech.
V-E-G-A-N. Vegans, like vegetarians, do not consume the meat of any land or marine animals. Vegans, however, unlike vegetarians, also refrain from eating cheese, milk, eggs, honey or any animal product, whatsoever.
But putting a "Coexist" bumper sticker on your car, wearing a "What would Jesus do?" bracelet, or sporting a "Peace and Love and Sunshine" t-shirt: That is not "getting involved"! I understand that we are all on a journey in life.
(It's a seed) Radishes? Raspberries?
And when I say 'empathy', what I'm saying is: place yourself in the position of the animals, and start to view this issue from the animals' point of view. From the victims' point of view. When you examine any form of injustice, whether humans are victims or animals are victims, please remember the victim's point of view.

"And those earthquakes...The one in Chile, and Haiti...Aww, that was SO sad!" No shit, it was sad. Since when, does 'feeling sad' about an obvious tragedy, or 'believing in' something, make the world a better place, or make somebody a good person?
You want to talk about pouring salt into somebody else's wound, 98% !! And I repeat this stat, ‏98% of animals who are abused and killed on this planet, are abused and killed by the meat, dairy and egg industries. This is where all the harm is taking place!
Trans fatty acids. Animal protein. And I'll repeat that last one, that nobody wants to hear about - animal protein.
"Strong bones, strong body." "Milk does a body good." "Got milk?" Check it out with the USDA:
Like it's been laced with weed, crack, ecstasy, morphine, and the antidote. Most people can't even fathom one meal, let alone one day, or a lifetime without cheese.
Actonel,
Boniva,
Citracal. You got to be kidding me! Calcium supplements in America?!
Fibercon,
Fibersure, and Benefiber.
If people ate a frickin' apple or a pear once in awhile, nobody would need help taking a shit. Now pay attention, and look around and see what's going on. Now with all this being said, we've established the four reasons why people eat meat, cheese, milk and eggs.
Now, tempeh is a fermented version of soy, so it tastes a little different than the other stuff, but keep in mind, I would not recommend products to you if they didn't taste fantastic. I am trying to win you over, so you go veg. I'm not showing you every product we have, some of our products suck!
Good news: there's Amy's, Morningstar Farms, Dr. Praeger's, Sunshine burgers and Gardenburger, all the different tastes and textures. And if you're looking for no soy, a different kind of mock meat in you diet, A new company called Bahama...
Lightlife also has vegan pepperoni which is ready to eat directly out of the bag. If you get some of this vegan pepperoni, buy yourself a Tofutti Pan Pizza with Tofutti soy cheese on it -
Tofutti also has cream cheese, sour cream and ice cream as well - before it goes in the oven or after it comes out of the oven, slaps some pepperoni on there and you got yourself a pizza. Remember there is soy milk and rice milk, almond milk, hemp milk, coconut milk, oat milk, hazelnuts milk. Seven vegan milks on the market.
And actually human women do this too - it's not Morphine but in cows it is, a version of Morphine - Casomorphins. That's why people are so hooked on cheese, gotta have their daily fix of Morphine. Does anybody know what an egg actually is from a hen?
"Wait, you just eat yams for dinner?! I don't know man, that's kinda weird..." Okay
So before we get started with the entire course, let's take a look at what a team actually could accomplish at the end of this process. Now imagine you had 10 weeks or months or a year to go do this. You'd actually be able to do a lot.
- five days they personally got out of the building and spoke to 169 customers and had 190 people come to their website. And as we saw two things, they were in the class. Let's take a look at what their business model canvas started with and evolved to.
We've just been talking about getting customers in a physical channel, but what's really interesting is most startups kind of forget that it's much more expensive to get a customer than it is to keep one. Yet, we seem to go from order to order or user to user forgetting about thinking about all the time is how can we extract more dollars or usage or whatever is important to us from our existing customers. How we do that is the first thing we need to do is make sure our existing customers we've just gotten don't go away, and so if you're in business long enough, you'll start thinking about how to keep customers.
The question today is not: Why did we invade Afghanistan? The question is: why are we still in Afghanistan one decade later?
In Sangin where I was sick in 2002, the nearest health clinic was within three days walk. Today, there are 14 health clinics in that area alone. There was amazing improvements.
2005, Anthony Fitzherbert, an agricultural engineer, could travel through Helmand, could stay in Nad Ali, Sangin and Ghoresh, which are now the names of villages where fighting is taking place. Today, he could never do that. So the idea that we deployed the troops to respond to the Taliban insurgency is mistaken.
Beginning in 2004, every general came in saying, "I've inherited a dismal situation, but finally I have the right resources and the correct strategy, which will deliver," in General Barno's word in 2004, the "decisive year."
Well guess what? It didn't. But it wasn't sufficient to prevent General Abuzaid saying that he had the strategy and the resources to deliver, in 2005, the "decisive year."
Or General David Richards to come in 2006 and say he had the strategy and the resources to deliver the "crunch year." Or in 2007, the Norwegian deputy foreign minister, Espen Eide, to say that that would deliver the "decisive year." Or in 2008, Major General Champoux to come in and say he would deliver the "decisive year."
(Applause) How do we allow any of this to happen? Well the answer, of course, is, if you spend 125 billion or 130 billion dollars a year in a country, you co-opt almost everybody.
(Applause) Thank you. Thank you very much.
(Applause) Thank you. Thank you.
(Applause) Bruno Giussani: Rory, you mentioned Libya at the end.
BG: Rory, thank you very much.
RS: Thank you.
(BG: Thank you.)
In the last video, we learned that an ellipse can be defined as the locus of all points where the sum of the distances to two special points, called foci-- and let me draw this all out, so that's my x-axis-- the sum of the distance to these two special points, called focuses or foci, is a constant. So if this is my ellipse-- I'll draw it out, that looks about where I want it to be right around, that looks about right-- it's centered at the origin, doesn't have to be, but for our purposes, let's make it centered on the origin. If this is one focus point right here, and this is the other focus point, this ellipse could be defined as the set of all points, or the locus of all points, where if I take the distance of any one of these points that exist on the ellipse and take the distance to each of the locuses-- sorry, each of the focuses-- if I take that-- nope, I don't want to do that-- if I take that distance and add it to this distance, so
I'll use blue. Let's say the ellipse looks like that. In this case, our semi-major radius is now in the y direction, so this is b, this is a, and in this case, b is greater than a, because the ellipse is tall and skinny.
Watch the Inner tendencies that go towards temporary happiness as separate... What do we want? We keep on singing that
"I...don't want.... any temporary things" Everybody knows that!!! Then what do we want?
What expression can be used to show dividing 18 boxes into two equals stacks? Find the expression three times using different ways to write division. Find the value of the expression.
So I have 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12-- almost there-- 13, 14, 15, 16, 17, 18. So those are my 18 boxes, and I divide them into two equals stacks or two equal groups. So if I want to divide these into two different groups that have the same number of boxes, I could just eyeball it, and say, well, let's make these top ones one group.
I have been asked for some intuition as to why, let's say, a to the minus b is equal to one over a to the b. And before I give you the intuition, I want you to just realize that this really is a definition.
Welcome to the presentation on level two addition. Well I think we should get started with some problems, and hopefully as we work through them, you'll have an understanding of how to do these types of problems. Let's see...
11 is here, right? This is 11. And we're adding 4.
Okay. 8+7 -- I'll tell you, frankly, even to this day, I sometimes get confused with 8+7.
8+7. And this time I'm not going to start at 0, I'll start at like 5, because, you know, if you keep going you'll get to 0 eventually. So let's see you get 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, and so on
35. And you might ask, well, does that make sense that 28+7=35? And there's a couple of ways I'd like to think about this.
8+7=15.
18+7 -- you're probably saying, Sal, where are you getting the 18 from, but take my word for it.
18+7=25.
28+7=35 which is the one that we just did. That is a check mark. And if you kept going, you said 38+7, that actually equals 45.
If I add 5, I get 33.
If I add 6, I get 34. And if I add 7, I get 35 again. Right, all I did is I kept saying oh, if I had one more
9+9 it turns out is 18. 9+9 is equal to 18...so 9+9... and you put the 8 down here and you carry the 1. And now you just say 1+9.
1+ 9=10. And so there's nowhere to carry this 1, so you write the whole thing down here. So 99+9=108.
Well 6+7=13, right? If you get confused, draw out everything again. And then you get 1+5.
1+5=6.
63. And you might want to give yourself a bunch of problems and I think you're also now, if you understand what we did, ready to try the level 2 addition problems. Have fun!
Just some tactics in figuring out pains, how to rank each pain that your products and/or services kill, according to the intensity for the customer, and what you are looking for is trying to understand--"Is this a lifesaving pain" or "Yeah, you know I'd live with this for years-- we could live with it for another couple of years." How important is it in the list of pains that customers have in the area that you're serving. And the other thing you want to think about is not only how intense is the pain but how often does it occur.
Write 5 and 1/4 as an improper fraction. An improper fraction is just a pure fraction where the numerator is greater than the denominator. This right here, it's not a pure fraction.
So let's think about 5.
Five is 5 wholes, or if you're thinking of pie, we could draw literally five pies. Let me just cut up the pies from the get go into four pieces since we're dealing with fourths.
5 literally represents-- so let me circle all of this together. That is the 5 part right there. That is what 5 literally represents.
4 pieces per pie times 5 pies is equal to 20 pieces. Or another way to think of it, since each piece is a fourth, this is also equal to 20 times 1/4, or you could just write this as being equal to 20/4. So we have 5 whole pies is equal to 20 fourths.
20 fourths. Or we could write it as 20/4. I've kind of done the same thing twice.
20/4 or 20 pieces, where each piece is 1/4. Now, the 1/4 right here represents literally one more fourth of a pie or one more piece of a pie, so let me draw another pie here. So that is another pie.
5 and 1/4 can be rewritten as the same thing as 5 plus 1/4, which is the same thing as-- we just saw that five whole pies is the same thing as 20/4. And to see that these are the same thing, you literally just divide 4 into 20. You get 5, and nothing is left over.
So 5 is the same thing as 20/4, and then this plus 1/4 is the same thing as plus 1/4. So if I have 20 fourths and I add one more fourth to it, how many fourths do I have? Well, I have 21.
1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20. But a quicker way is to say, well, we have five pies. Each of them have four pieces.
5 times 4 is 20. This 1/4 right here represents one piece plus one piece, so total we're going to have 21 pieces. So we have 21 pieces, where each piece is 1/4, so we could say we have 21 times 1/4 or 21 fourths pieces of pie.
So 1 plus-- or actually, let me do it the way I tend to think of it. What I do is I take 4 times 5. So let me write that down and I want to color code it.
4 times 5, and then to that, I add this numerator. So I literally do 4 times 5 plus 1, which is-- so this is equal to 4 times 5 is 20, plus 1 is 21, and then that's over 4, so it's 21/4. And all of this is kind of a fast way to do it.
Hi, I'm Jeff Law and I'm from Haas Automation I'm going to talk today about our offset filtering functions
The Haas control is capable of holding 200 tool offsets and 105 work offsets but the typical CNC program isn't going to use all of them For example, this program uses four tool offsets and one work offset When I'm running a CNC program I'm really only interested in displaying the offsets that are active
The Haas control now has a new function that lets me filter out all of the unused offsets To enable this function I go to the "Settings" page And it's setting 201, "2-0-1" press the "down" arrow and I press the "right" arrow to toggle this function on
I've run my program all the way through and the offsets are filtered If I want to see them displayed I can go to the "Offset" screen and there are my four tool offsets
What's the purpose of the minimum viable product? Take a look at the list and pick the appropriate answer.

Let's add 249 to 383. Now, the first thing you want to do with any type of addition problem, especially when you have multiple digits, is to write the two numbers above and below each other. So we have 200-- let me write a little bigger than that-- 249 plus 383.
1 plus 4 plus 8 is what?
5 plus 8, that is 13. I'll write it like this. Actually, this is in the tens place, so it actually represents 130, but you don't have to think about that.
1 plus 2 is 3 plus 3 is 6. So that is equal to 6. So we write it right over here.
Today I'm going to talk about unexpected discoveries. Now I work in the solar technology industry. And my small startup is looking to force ourselves into the environment by paying attention to ...
... paying attention to crowd-sourcing. It's just a quick video of what we do. Huh.
(Laughter)
(Music)
This is not ...
(Laughter) Okay.
(Laughter) Solar technology is ... Oh, that's all my time?
First question is about star networks. A star network is a network that has a single node in the center that is connected to all the rest of the nodes in the graph directly. So here is a star network with five nodes that has one, two, three, four edges and what I want you to do is write a
One way to think about this is, imagine this last level is filled in all the way to the end. Then what's happening here is we have, how many nodes we have at that level? We have half as many at the level above because each of the nodes shares a parent with one of the other nodes and again half and again half and again half.
Are you familiar with the word symbiosis? It's a fancy term for a partnership between two different species, such as bees and flowers. In a symbiosis, both species depend on each other.
Let's take up this target business model and customer development but you know before we even begin one of the first questions I tend to ask is what is a company? What is it that I'm trying to actually start? Just for the sake this class, I think we ought to just use this definition.
What I'd like you to do is grab the canvas element that we've already specified in our HTML page and set its width and height attributes appropriately.
To see if it's a tree, the first thing we need to do is to see if the graph is connected. Looking through the 8 graphs, you can see that the fourth graph is not connected. Recoloring the edges, we can see that these three nodes are not connected to these three nodes.
Let's look right now at the analysis of the algorithm. What's the running time of Dijkstra in terms of the number of nodes (n) and edges (m) when heaps are used? The kinds of heaps we've been talking about to be able to find the shortest distance so far so we can lock that down and run.
To try to understand the relationship between edges and nodes in a planar graph we're going to use a result due to Euler--same Euler as before. To do that we're going to need another concept about planar graphs. Here's a planar graph on five nodes.
Opinions Let's talk a little about the matter related to Opinions, today. While it's still a hot topic - Opinions
Now, let's take this topic of vibrations. That for one person.... What do you want to say?
Eh...
For one person, we feel that during the unfolding of his merit karma (puniya), he is right, And when his demerit karma (paap) unfolds we feel he is wrong. Even when our merit and demerit accounts are perverse, our vision too will be distorted.
Let's do [samayik] on speech (vani). Related to speech... All our speech, what kind of speech do we have [in interactions] with other individuals?
I was listening to Niruma's satsang this afternoon, at 3:30 pm, and a lady was saying that when I walk on grass, I feel a lot of suffering Niruma doesn't say a word, and then she says [in such a way that]... not a single foundation would be hurt of the Jain religion the lady believed in. The satsang went on for about 15 minutes but Niruma guiding her in accordance with the Jain principles did not show her a single mistake of the principles she believed in.
Dimple says to her, "Do you know what your mother has said about you?" And when she was shown all the positive things her mother had spoken of her, her whole internal suffering immediately came to an end. Right?
Something like this had happened, right? She had immense negativity for her mother. But after telling her just four to five things...that your mum was saying this about you, ...
It is like you said, just four or five days before her mother was talking about her positives. Her mother was talking to Niruma about her positive and we were all listening in. Niruma would talk to her for hours but she wouldn't understand.
Give me the strength to do a samayik with pure awareness of the Self (shudha upyog), For individuals who are close [to me] In worldly interactions [where] any hostile sentences are being said, [where] hostile speech is being said, during that time inner opinions that exist within me [recognize] what kind [of opinions] are they to recognize all of them, to become opinion-free for the opposite person, to set that kind of absolute knowledge (gnan)
Give me the absolute energy (shakti) to do such a samayik. Towards any individual No hostile speech should ever be spoken
Imagine two people who share an important secret have to split up. This requires them to communicate private information from a distance. However, an eavesdropper named Eve also wants this information, and has the ability to intercept their messages.
Think of [ciphers] as virtual locks.
Ciphers allow Alice and Bob to scramble and descramble their messages so that they would appear meaningless if Eve intercepted them. Cryptography has been around for thousands of years. It has decided wars, and is at the heart of the worldwide communication network today.
 I now want to solve some inequalities that also have absolute values in them. And if there's any topic in algebra that probably confuses people the most, it's this.
And we begin with a very simple question, or -- not a question -- a challenge. We need to build a machine which takes an input -- (And that input is some integer, 'x.') And all that machine needs to do is output 'true' or 'false.'
I've now done a bunch of videos on thermodynamics, both in the chemistry and the physics playlist, and I realized that I have yet to give you, or at least if my memory serves me correctly, I have yet to give you the first law of thermodynamics. And I think now is as good a time as any.
And it's a good one. It tells us that energy-- I'll do it in this magenta color-- energy cannot be created or destroyed, it can only be transformed from one form or another. So energy cannot be created or destroyed, only transformed.
So let's think about a couple of examples of this. And we've touched on this when we learned mechanics and kinetics in our physics playlist, and we've done a bunch of this in the chemistry playlist as well. So let's say I have some rock that I just throw as fast as I can straight up.
And here we have something called the internal energy. The internal energy of a system. Once again this is a macrostate, or you could call it a macro description of what's going on.
Let me go back to my example-- that I had in the past, that I did in our previous video, if you're watching these in order-- of I have, you know, some gas with some movable ceiling at the top. That's its movable ceiling. That can move up and down.
The internal energy literally is all of the energy that's in the system. So it includes, and for our purposes, especially when you're in a first-year chemistry course, it's the kinetic energy of all the atoms or molecules. And in a future video, I'll actually calculate it for how much kinetic energy is there in a container.
And you could see this multiple ways. Sometimes it's written like this. Sometimes it's written that the change in internal energy is equal to the heat added to the system, plus the work done on the system.
Or energy is being transferred into my system. I'll give a lot more examples of what exactly that means in the next video. But I just want to make you comfortable with either of these.
So remember, we tested out this lesson with the song on 20 students. And we got these means. Where do these fall on the sampling distributions in green?
The most massive tsunami perfect storm is bearing down upon us. This perfect storm is mounting a grim reality, increasingly grim reality, and we are facing that reality with the full belief that we can solve our problems with technology, and that's very understandable. Now, this perfect storm that we are facing is the result of our rising population, rising towards 10 billion people,
What are we going to do? There is only one option, I'll repeat to you, only one option
Thank you, Chris. Chris Anderson: Thank you.
You know, one of the intense pleasures of travel and one of the delights of ethnographic research is the opportunity to live amongst those who have not forgotten the old ways, who still feel their past in the wind, touch it in stones polished by rain, taste it in the bitter leaves of plants. Just to know that Jaguar shamans still journey beyond the Milky Way, or the myths of the Inuit elders still resonate with meaning, or that in the Himalaya, the Buddhists still pursue the breath of the Dharma, is to really remember the central revelation of anthropology, and that is the idea that the world in which we live does not exist in some absolute sense, but is just one model of reality, the consequence of one particular set of adaptive choices that our lineage made, albeit successfully, many generations ago. And of course, we all share the same adaptive imperatives.
And I know there's some of you who say, "Well, wouldn't it be better, wouldn't the world be a better place if we all just spoke one language?" And I say, "Great, let's make that language Yoruba. Let's make it Cantonese.
That's why the Voodooists like to say that "You white people go to church and speak about God. We dance in the temple and become God." And because you are possessed, you are taken by the spirit -- how can you be harmed?
And the priest steps back and says, "You see? It's really as I've told you. It is that beautiful.

Go from Corlears Hook to Coenties Slip, and from thence, by Whitehall, northward. What do you see?--Posted like silent sentinels all around the town, stand thousands upon thousands of mortal men fixed in ocean reveries. Some leaning against the spiles; some seated upon the pier-heads; some looking over the bulwarks of ships from China; some high aloft in the rigging, as if striving to get a still better seaward peep.
He desires to paint you the dreamiest, shadiest, quietest, most enchanting bit of romantic landscape in all the valley of the Saco. What is the chief element he employs?

Why did the poor poet of Tennessee, upon suddenly receiving two handfuls of silver, deliberate whether to buy him a coat, which he sadly needed, or invest his money in a pedestrian trip to Rockaway Beach? Why is almost every robust healthy boy with a robust healthy soul in him, at some time or other crazy to go to sea? Why upon your first voyage as a passenger, did you yourself feel such a mystical vibration, when first told that you and your ship were now out of sight of land?
The transition is a keen one, I assure you, from a schoolmaster to a sailor, and requires a strong decoction of Seneca and the Stoics to enable you to grin and bear it. But even this wears off in time. What of it, if some old hunks of a sea- captain orders me to get a broom and sweep down the decks?
Well, then, however the old sea-captains may order me about--however they may thump and punch me about, I have the satisfaction of knowing that it is all right; that everybody else is one way or other served in much the same way--either in a physical or metaphysical point of view, that is; and so the universal thump is passed round, and all hands should rub each other's shoulder- blades, and be content. Again, I always go to sea as a sailor, because they make a point of paying me for my trouble, whereas they never pay passengers a single penny that I ever heard of. On the contrary, passengers themselves must pay.

Though I cannot tell why it was exactly that those stage managers, the Fates, put me down for this shabby part of a whaling voyage, when others were set down for magnificent parts in high tragedies, and short and easy parts in genteel comedies, and jolly parts in farces--though I cannot tell why this was exactly; yet, now that I recall all the circumstances, I think I can see a little into the springs and motives which being cunningly presented to me under various disguises, induced me to set about performing the part I did, besides cajoling me into the delusion that it was a choice resulting from my own unbiased freewill and discriminating judgment. Chief among these motives was the overwhelming idea of the great whale himself.
Patagonian sights and sounds, helped to sway me to my wish. With other men, perhaps, such things would not have been inducements; but as for me, I am tormented with an everlasting itch for things remote.
Bedford, thence to embark on their voyage, it may as well be related that I, for one, had no idea of so doing. For my mind was made up to sail in no other than a Nantucket craft, because there was a fine, boisterous something about everything connected with that famous old island, which amazingly pleased me. Besides though New Bedford has of late been gradually monopolising the business of whaling, and though in this matter poor old Nantucket is now much behind her, yet
Nantucket was her great original--the Tyre of this Carthage;--the place where the first dead American whale was stranded. Where else but from Nantucket did those aboriginal whalemen, the Red-Men, first sally out in canoes to give chase to the Leviathan? And where but from Nantucket, too, did that first adventurous little sloop put forth, partly laden with imported cobblestones--so goes the story--to throw at the whales, in order to discover when they were nigh enough to risk a harpoon from the bowsprit?
Bedford, ere I could embark for my destined port, it became a matter of concernment where I was to eat and sleep meanwhile. It was a very dubious-looking, nay, a very dark and dismal night, bitingly cold and cheerless. I knew no one in the place.
But "The Crossed Harpoons," and "The Sword- Fish?"--this, then must needs be the sign of "The Trap." However, I picked myself up and hearing a loud voice within, pushed on and opened a second, interior door. It seemed the great Black Parliament sitting in Tophet.
Moving on, I at last came to a dim sort of light not far from the docks, and heard a forlorn creaking in the air; and looking up, saw a swinging sign over the door with a white painting upon it, faintly representing a tall straight jet of misty spray, and these words underneath--"The Spouter Inn:--Peter Coffin." Coffin?--Spouter?--Rather ominous in that particular connexion, thought I.
Euroclydon, nevertheless, is a mighty pleasant zephyr to any one in-doors, with his feet on the hob quietly toasting for bed.
"In judging of that tempestuous wind called Euroclydon," says an old writer--of whose works I possess the only copy extant--"it maketh a marvellous difference, whether thou lookest out at it from a glass window where the frost is all on the outside, or whether thou observest it from that sashless window, where the frost is on both sides, and of which the wight Death is the only glazier." True enough, thought I, as this passage occurred to my mind--old black-letter, thou reasonest well. Yes, these eyes are windows, and this body of mine is the house.
Euroclydon! says old Dives, in his red silken wrapper--(he had a redder one afterwards) pooh, pooh! What a fine frosty night; how Orion glitters; what northern lights! Let them talk of their oriental summer climes of everlasting conservatories; give me the privilege of making my own summer with my own coals.
Upon entering the place I found a number of young seamen gathered about a table, examining by a dim light divers specimens of SKRlMSHANDER. I sought the landlord, and telling him I desired to be accommodated with a room, received for answer that his house was full--not a bed unoccupied. "But avast," he added, tapping his forehead, "you haint no objections to sharing a harpooneer's blanket, have ye?
Supper'll be ready directly." I sat down on an old wooden settle, carved all over like a bench on the Battery. At one end a ruminating tar was still further adorning it with his jack-knife, stooping over and diligently working away at the space between his legs.
"Landlord," I whispered, "that aint the harpooneer is it?" "Oh, no," said he, looking a sort of diabolically funny, "the harpooneer is a dark complexioned chap. He never eats dumplings, he don't--he eats nothing but steaks, and he likes 'em rare."
"He'll be here afore long," was the answer. I could not help it, but I began to feel suspicious of this "dark complexioned" harpooneer. At any rate, I made up my mind that if it so turned out that we should sleep together, he must undress and get into bed before I did.
Hurrah, boys; now we'll have the latest news from the Feegees."
A tramping of sea boots was heard in the entry; the door was flung open, and in rolled a wild set of mariners enough. Enveloped in their shaggy watch coats, and with their heads muffled in woollen comforters, all bedarned and ragged, and their beards stiff with icicles, they seemed an eruption of bears from Labrador. They had just landed from their boat, and this was the first house they entered.
Bulkington! where's Bulkington?" and darted out of the house in pursuit of him. It was now about nine o'clock, and the room seeming almost supernaturally quiet after these orgies, I began to congratulate myself upon a little plan that had occurred to me just previous to the entrance of the seamen. No man prefers to sleep two in a bed.
"Just as you please; I'm sorry I cant spare ye a tablecloth for a mattress, and it's a plaguy rough board here"--feeling of the knots and notches. "But wait a bit, Skrimshander; I've got a carpenter's plane there in the bar--wait, I say, and I'll make ye snug enough."
"Can't sell his head?--What sort of a bamboozingly story is this you are telling me?" getting into a towering rage. "Do you pretend to say, landlord, that this harpooneer is actually engaged this blessed Saturday night, or rather Sunday morning, in peddling his head around this town?"
"That's precisely it," said the landlord, "and I told him he couldn't sell it here, the market's overstocked." "With what?" shouted I.
"With heads to be sure; ain't there too many heads in the world?" "I tell you what it is, landlord," said I quite calmly, "you'd better stop spinning that yarn to me--I'm not green." "May be not," taking out a stick and whittling a toothpick, "but I rayther guess you'll be done BROWN if that ere harpooneer hears you a slanderin' his head."
"Sartain, and that's the very reason he can't sell it, I guess." "Landlord," said I, going up to him as cool as Mt. Hecla in a snow-storm--"landlord, stop whittling.
"Wall," said the landlord, fetching a long breath, "that's a purty long sarmon for a chap that rips a little now and then. But be easy, be easy, this here harpooneer I have been tellin' you of has just arrived from the south seas, where he bought up a lot of 'balmed New Zealand heads (great curios, you know), and he's sold all on 'em but one, and that one he's trying to sell to-night, cause to-morrow's Sunday, and it would not do to be sellin' human heads about the streets when folks is goin' to churches. He wanted to, last Sunday, but I stopped him just as he was goin' out of the door with four heads strung on a string, for all the airth like a string of inions."
"He pays reg'lar," was the rejoinder. "But come, it's getting dreadful late, you had better be turning flukes--it's a nice bed; Sal and me slept in that ere bed the night we were spliced. There's plenty of room for two to kick about in that bed; it's an almighty big bed that.
Arter that, Sal said it wouldn't do. Come along here, I'll give ye a glim in a jiffy;" and so saying he lighted a candle and held it towards me, offering to lead the way. But I stood irresolute; when looking at a clock in the corner, he exclaimed "I vum it's Sunday--you won't see that harpooneer to-night; he's come to anchor somewhere-- come along then; DO come; WON'T ye come?"
I remembered a story of a white man--a whaleman too--who, falling among the cannibals, had been tattooed by them. I concluded that this harpooneer, in the course of his distant voyages, must have met with a similar adventure. And what is it, thought I, after all!
Remembering the embalmed head, at first I almost thought that this black manikin was a real baby preserved in some similar manner. But seeing that it was not at all limber, and that it glistened a good deal like polished ebony, I concluded that it must be nothing but a wooden idol, which indeed it proved to be. For now the savage goes up to the empty fire-place, and removing the papered fire- board, sets up this little hunch-backed image, like a tenpin, between the andirons.
"Landlord! Watch! Coffin!
"Speak-e! tell-ee me who-ee be, or dam-me, I kill-e!" again growled the cannibal, while his horrid flourishings of the tomahawk scattered the hot tobacco ashes about me till I thought my linen would get on fire. But thank heaven, at that moment the landlord came into the room light in hand, and leaping from the bed I ran up to him. "Don't be afraid now," said he, grinning again, "Queequeg here wouldn't harm a hair of your head."
"I thought ye know'd it;--didn't I tell ye, he was a peddlin' heads around town?--but turn flukes again and go to sleep.
Queequeg, look here--you sabbee me, I sabbee--you this man sleepe you--you sabbee?"
"Me sabbee plenty"--grunted Queequeg, puffing away at his pipe and sitting up in bed. "You gettee in," he added, motioning to me with his tomahawk, and throwing the clothes to one side. He really did this in not only a civil but a really kind and charitable way.
"Good night, landlord," said I, "you may go." I turned in, and never slept better in my life. > -Chapter 4.
At last I must have fallen into a troubled nightmare of a doze; and slowly waking from it--half steeped in dreams--I opened my eyes, and the before sun-lit room was now wrapped in outer darkness. Instantly I felt a shock running through all my frame; nothing was to be seen, and nothing was to be heard; but a supernatural hand seemed placed in mine. My arm hung over the counterpane, and the nameless, unimaginable, silent form or phantom, to which the hand belonged, seemed closely seated by my bed-side.
"Queequeg!--in the name of goodness,
Queequeg, wake!" At length, by dint of much wriggling, and loud and incessant expostulations upon the unbecomingness of his hugging a fellow male in that matrimonial sort of style, I succeeded in extracting a grunt; and presently, he drew back his arm, shook himself all over like a Newfoundland dog just from the water, and sat up in bed, stiff as a pike-staff, looking at me, and rubbing his eyes as if he did not altogether remember how I came to be there, though a dim consciousness of knowing something about me seemed slowly dawning over him. Meanwhile, I lay quietly eyeing him, having no serious misgivings now, and bent upon narrowly observing so curious a creature.
Queequeg made, staving about with little else but his hat and boots on; I begged him as well as I could, to accelerate his toilet somewhat, and particularly to get into his pantaloons as soon as possible. He complied, and then proceeded to wash himself. At that time in the morning any Christian would have washed his face; but Queequeg, to my amazement, contented himself with restricting his ablutions to his chest, arms, and hands.
like the Andes' western slope, to show forth in one array, contrasting climates, zone by zone.
"Grub, ho!" now cried the landlord, flinging open a door, and in we went to breakfast. They say that men who have seen the world, thereby become quite at ease in manner, quite self-possessed in company. Not always, though:
Ledyard, the great New England traveller, and Mungo Park, the Scotch one; of all men, they possessed the least assurance in the parlor. But perhaps the mere crossing of Siberia in a sledge drawn by dogs as Ledyard did, or the taking a long solitary walk on an empty stomach, in the negro heart of Africa, which was the sum of poor Mungo's performances--this kind of travel, I say, may not be the very best mode of attaining a high social polish.
Wapping. In these last-mentioned haunts you see only sailors; but in New Bedford, actual cannibals stand chatting at street corners; savages outright; many of whom yet carry on their bones unholy flesh. It makes a stranger stare.
Brighggians, and, besides the wild specimens of the whaling-craft which unheeded reel about the streets, you will see other sights still more curious, certainly more comical. There weekly arrive in this town scores of green Vermonters and New Hampshire men, all athirst for gain and glory in the fishery. They are mostly young, of stalwart frames; fellows who have felled forests, and now seek to drop the axe and snatch the whale- lance.
MACY, AND SAMUEL GLElG, Forming one of the boats' crews OF THE SHlP ELlZA Who were towed out of sight by a Whale, On the Off- shore Ground in the PAClFIC, December 31st, 1839. THlS MARBLE Is here placed by their surviving SHlPMATES. SACRED TO THE MEMORY OF The late CAPTAlN EZEKlEL HARDY, Who in the bows of his boat was killed by a Sperm Whale on the coast of Japan, AUGUST 3d, 1833.
The Pulpit. I had not been seated very long ere a man of a certain venerable robustness entered; immediately as the storm-pelted door flew back upon admitting him, a quick regardful eyeing of him by all the congregation, sufficiently attested that this fine old man was the chaplain. Yes, it was the famous Father Mapple, so called by the whalemen, among whom he was a very great favourite.
Halting for an instant at the foot of the ladder, and with both hands grasping the ornamental knobs of the man-ropes, Father Mapple cast a look upwards, and then with a truly sailor-like but still reverential dexterity, hand over hand, mounted the steps as if ascending the main-top of his vessel. The perpendicular parts of this side ladder, as is usually the case with swinging ones, were of cloth-covered rope, only the rounds were of wood, so that at every step there was a joint. At my first glimpse of the pulpit, it had not escaped me that however convenient for a ship, these joints in the present instance seemed unnecessary.
Between the marble cenotaphs on either hand of the pulpit, the wall which formed its back was adorned with a large painting representing a gallant ship beating against a terrible storm off a lee coast of black rocks and snowy breakers. But high above the flying scud and dark- rolling clouds, there floated a little isle of sunlight, from which beamed forth an angel's face; and this bright face shed a distinct spot of radiance upon the ship's tossed deck, something like that silver plate now inserted into the Victory's plank where Nelson fell. "Ah, noble ship," the angel seemed to say, "beat on, beat on, thou noble ship, and bear a hardy helm; for lo! the sun is breaking through; the clouds are rolling off--serenest azure is at hand."
What could be more full of meaning?--for the pulpit is ever this earth's foremost part; all the rest comes in its rear; the pulpit leads the world. From thence it is the storm of God's quick wrath is first descried, and the bow must bear the earliest brunt. From thence it is the God of breezes fair or foul is first invoked for favourable winds.
Midships! midships!" There was a low rumbling of heavy sea-boots among the benches, and a still slighter shuffling of women's shoes, and all was quiet again, and every eye on the preacher. He paused a little; then kneeling in the pulpit's bows, folded his large brown hands across his chest, uplifted his closed eyes, and offered a prayer so deeply devout that he seemed kneeling and praying at the bottom of the sea.
"The ribs and terrors in the whale, Arched over me a dismal gloom, While all God's sun-lit waves rolled by, And lift me deepening down to doom. "I saw the opening maw of hell, With endless pains and sorrows there;
"Shipmates, this book, containing only four chapters--four yarns--is one of the smallest strands in the mighty cable of the Scriptures. Yet what depths of the soul does Jonah's deep sealine sound! what a pregnant lesson to us is this prophet! What a noble thing is that canticle in the fish's belly!
Shipmates, it is a two-stranded lesson; a lesson to us all as sinful men, and a lesson to me as a pilot of the living God. As sinful men, it is a lesson to us all, because it is a story of the sin, hard- heartedness, suddenly awakened fears, the swift punishment, repentance, prayers, and finally the deliverance and joy of Jonah.
There lurks, perhaps, a hitherto unheeded meaning here. By all accounts Tarshish could have been no other city than the modern Cadiz. That's the opinion of learned men.
Frighted Jonah trembles, and summoning all his boldness to his face, only looks so much the more a coward. He will not confess himself suspected; but that itself is strong suspicion. So he makes the best of it; and when the sailors find him not to be the man that is advertised, they let him pass, and he descends into the cabin. "'Who's there?' cries the Captain at his busy desk, hurriedly making out his papers for the Customs--'Who's there?'
In this world, shipmates, sin that pays its way can travel freely, and without a passport; whereas Virtue, if a pauper, is stopped at all frontiers. So Jonah's Captain prepares to test the length of Jonah's purse, ere he judge him openly. He charges him thrice the usual sum; and it's assented to.
'Thou lookest like it,' says the Captain, 'there's thy room.' Jonah enters, and would lock the door, but the lock contains no key. Hearing him foolishly fumbling there, the Captain laughs lowly to himself, and mutters something about the doors of convicts' cells being never allowed to be
locked within. All dressed and dusty as he is, Jonah throws himself into his berth, and finds the little state-room ceiling almost resting on his forehead. The air is close, and Jonah gasps.
"Like one who after a night of drunken revelry hies to his bed, still reeling, but with conscience yet pricking him, as the plungings of the Roman race-horse but so much the more strike his steel tags into him; as one who in that miserable plight still turns and turns in giddy anguish, praying God for annihilation until the fit be passed; and at last amid the whirl of woe he feels, a deep stupor steals over him, as over the man who bleeds to death, for conscience is the wound, and there's naught to staunch it; so, after sore wrestlings in his berth, Jonah's prodigy of ponderous misery drags him drowning down to sleep. "And now the time of tide has come; the ship casts off her cables; and from the deserted wharf the uncheered ship for Tarshish, all careening, glides to sea. That ship, my friends, was the first of recorded smugglers! the contraband was
Shipmates, I do not place Jonah before you to be copied for his sin but I do place him before you as a model for repentance. Sin not; but if you do, take heed to repent of it like Jonah." While he was speaking these words, the howling of the shrieking, slanting storm without seemed to add new power to the preacher, who, when describing Jonah's sea- storm, seemed tossed by a storm himself.
"Shipmates, God has laid but one hand upon you; both his hands press upon me. I have read ye by what murky light may be mine the lesson that Jonah teaches to all sinners; and therefore to ye, and still more to me, for I am a greater sinner than ye. And now how gladly would I come down from this mast-head and sit on the hatches there where you sit, and listen as you listen, while some one of you reads ME that other and more awful lesson which Jonah teaches to ME, as a pilot of the living God.
Yet even then beyond the reach of any plummet--'out of the belly of hell'--when the whale grounded upon the ocean's utmost bones, even then, God heard the engulphed, repenting prophet when he cried. Then God spake unto the fish; and from the shuddering cold and blackness of the sea, the whale came breeching up towards the warm and pleasant sun, and all the delights of air and earth; and 'vomited out Jonah upon the dry land;' when the word of the Lord came a second time; and Jonah, bruised and beaten--his ears, like two sea-shells, still multitudinously murmuring of the ocean--Jonah did the Almighty's bidding. And what was that, shipmates?

YouTube and Twitter and they're trying to see whether they can make their business viral by actually having customers who refer others. The key tenet of virality is can you get other people to do your marketing for free. And they are also going to work on targeted promotions.
Every story has a beginning... And this story's beginning goes back to 2004. At that time, there was a young history student at Ankara University who was also very interested in acting.
I hope to be successful in that show, and I want to be a permanent fixture in this sector. He started acting in the show, "Foreign Groom," the role offered as a result of the competition. From that moment, he became Kadir Sadikoglu for millions of Turkish viewers.
Zeki Demirkubuz. Cevat!... You are mistaken abi!
Zagor, don't get involved in this. Take Kamil out... What happens if I get involved?
In the 2006 "Kader," movie, for a role that barely lasted 10 minutes, he was so admired that he won two awards And, received the "Most Promising Young Actor" award for both SlYAD and CASOD

So, now we're in a good position to finally define this notion of NP-completeness that I mentioned in the beginning of the unit.
We can say some problem X is NP-complete if it satisfies two properties.
First, it has to be NP-hard, meaning that nothing in NP is harder then X. Which is to say that if you could solve X in polynomial time, you could use it to solve everything in NP in polynomial time.
And the second important property is that X itself is in NP. So its in the set and its as hard as anything in the set. So, it is in fact the hardest in this set.
Very often when you go to solve some, to develop some kind of algorithm to solve a problem and there just doesn't feel like there is anyway to get a foothold on it, uh, its a good idea to check: is NP-hard and is it in NP? If so, its NP-complete. And, uh, at this point now, tons of problems are known to be NP-complete.
NP-hard and therefore a polynomial time solution for that problem solves everything in NP. Do we know that the problem clique can be reduced to it? Given what we've said so far about what we've said so far about clique.
Welcome to the lathe soft jaw video series Brought to you by Haas Automation Soft jaws offer several benefits not provided by hard jaws
The clamping force on the part naturally decreases If the clamping pressure is set too high in an attempt to increase the clamping force The soft jaws will be distorted, actually decreasing grip force
Undersize jaws will grip along six edges, whereas oversize jaws will grip only along the center of each jaw Our program is set to cut at the nominal part diameter The soft jaws are clamping inwards on the boring ring at 100 psi
Once the jaws have been cut, make a shallow groove at the bottom of the jaws
Any work piece with sharp edges will now locate correctly against the jaw's back face Without this groove cut, a sharp-edged part will not locate correctly on the back face You will likely need to deburr the jaws when the machining is complete
In some cases, you won't be able to use the adjustable boring ring Because the part diameter is so large that the ring itself will block your cutting path That's exactly the case with this part here
Two step jaws are a good alternative to cutting two different jaw sets When part geometry is favorable, the larger pocket holds the uncut raw stock While the smaller pocket holds the half-finished part for the second operation
One of the things we keep asking our startups to think about is how big is this opportunity? That's just a fancy word for saying when you're all done and you're spending the next couple years in the startup are you going to make a million, or are you going to make a billion? That is, how potentially large is the opportunity?
Customer lifetime value is exactly what is says. What's the sum of all the revenue from day 1 purchase, so you're keeping them through all the grow activities you're undertaking. Lifetime value is the customer lifetime value from beginning to end, and just as a note, remember customer acquisition costs acquired over here, needs to be less than customer lifetime value.
I want you to take a look at this baby. What you're drawn to are her eyes and the skin you love to touch. But today I'm going to talk to you about something you can't see.
And what we're learning is going to shed some light on what the romantic writers and poets described as the "celestial openness" of the child's mind. What we see here is a mother in India, and she's speaking Koro, which is a newly discovered language. And she's talking to her baby.
The way to read this slide is to look at your age on the horizontal axis. (Laughter) And you'll see on the vertical your skill at acquiring a second language.
(Video) Ah, I love your big blue eyes -- so pretty and nice.
(Japanese) During the production of speech, when babies listen, what they're doing is taking statistics on the language that they hear.
We knew that, when monolinguals were tested in Taipei and Seattle on the Mandarin sounds, they showed the same pattern. Six to eight months, they're totally equivalent. Two months later, something incredible happens.
Here's what it looked like in the laboratory. (Mandarin) PK:
So what have we done to their little brains?
(Laughter) We had to run a control group to make sure that coming into the laboratory didn't improve your Mandarin skills. So a group of babies came in and listened to English.
(Applause)
What the Big Theta allows us to do is basically write complicated functions in a much simpler way. We can take a function like ½n² and just think of it as Θ(n²). And 8√n we can think of a just Θ(√n).
A complicated expression like this where we have n⁴, which is the term that grows the fastest, becomes Θ(n). The ln n--in fact, any base log n is Big Theta of any other base log n as long as it's a constant. I like to think in terms of base 2 logs, because I'm a computer scientist.
That's what we do. π² is something that doesn't grow with n, and it ends up being in the set Θ(1). It's just another constant. Just to beat this dead horse a little bit longer, let's use the definition of Big Theta to show that this expression that we determine for the growth in edges in a grid-- 2n - 2√n--really is just a linear function.
Intuitively, the idea being this function is growing like 2n minus something smaller than that. So, n should be underneath that. But let's just make show if c₁ is equal to 1, then we need n to be less than or equal to this expression.
A microbiologist has 1,256 microbes growing in culture. When he checks again after fifteen minutes, there are 2,283 microbes in the same culture, so they're growing pretty fast. Estimate the difference between the number of microbes at each check by rounding each number to the nearest ten.
That is the 8 right there. And you look at the place one below that. If that's 5 or greater, you round up.
2,280. Now, they want us to estimate the difference between the number of microbes at each check by rounding each number to the nearest ten, so we've done that part. We've rounded each number to the nearest ten.
0 minus 0. Well, that's just going to be 0.
8 minus 6 in the tens place, it's really 80 minus 60. That's going to be 2, but since it's in the tens place, it's 20, or you could just do 80 minus 60 is 20, so everything makes sense so far.
2 minus 2 is 0, and then 2 minus 1 is 1. So when we rounded each number to the nearest ten and then took the difference, our estimated difference is 1,020.
I decided when I was asked to do this that what I really wanted to talk about was my friend, Richard Feynman. I was one of the fortunate few that really did get to know him and enjoyed his presence. And I'm going to tell you about the Richard Feynman that I knew.
Feynman let them have it -- both barrels, right between the eyes. It was brutal; it was funny -- ooh, it was funny. But it was really brutal.
Dick -- he was my friend; I did call him Dick -- Dick and I had a little bit of a rapport. I think it may have been a special rapport that he and I had.
Feynman's style -- no, "style" is not the right word. "Style" makes you think of the bow tie he might have worn, or the suit he was wearing. It's something much deeper than that, but I can't think of another word for it.
I think he would have said, "I don't need this." But ... (Laughter) How should we honor Feynman?
"Google began as a research project in 1996." "This is a look at how search has evolved." Gomes:
And it was getting increasingly hard to find the piece of content you wanted. "Adwords" Mayer:
Mayer: In 1999 and 2000, we had a search engine that worked wonderfully, and it worked wonderfully for web pages. One of the things we saw was, as Google got better and better, users expected more and more from it.
When September 11th happened, we as Google were failing our users.
My friend Krishna and I were attending a conference at the time, and Krishna started thinking about the problem, saying, "If we could crawl news quickly, "and we can provide multiple points of view
"about the same story to our users, wouldn't it be amazing?" That was the birth of Google News specialized search service. Well, in 2002, one of the trends we started to see was that the web had become a lot more rich.
I would be able to walk up to a computer and say, "Hey, what is the best time for me to sow seeds in India, given that monsoon was early this year?" And once we can answer that question, which we don't today, people will be looking for answers to even more complex questions.
 Let's keep going with our 2008 Calculus BC free answer questions. So we're on problem number 2.
And this is noon, 12:00 noon, 1:00 pm, 9:00 pm.
All the tickets are sold by 9:00 pm. And they tell us it's twice differentiable. So that means that whatever function we're modeling this, this L of t, that it's continuous because it's differentiable.
So they don't give us any data on 5:30 pm.
They give us 4:00 pm and 7:00 pm, or t equals 5.5.
Show the computations that lead to your answer. Indicate the units of measure. So what do they want to know?
OK part b says, use a trapezoidal sum with three subintervals. Maybe I can make this a little bit bigger. Let me see if I can grow that a little bit.
The trapezoidal sum for the fourth. Actually I just realized. For some reason, YouTube used to let me do longer videos because I thought I was a partner.
Let's now expand our knowledge of calculus to the third dimension. So first of all, just what does a function look like in three dimensions?
What I want to do in this video is go over the math behind a mortgage loan. And this isn't really going to be a finance video. It's actually a lot more mathematical.
Now normally when you get a loan like this, your mortgage broker or your banker will look into some type of chart or type in the numbers into some type of computer program. And they'll say oh OK, your payment is going to be $1,200 per month. And if you pay that $1,200 per month over 360 months, at the end of those 360 months you will have paid off the $200,000 plus any interest that might have accrued.
You don't pay any mortgage payments. You're going to pay your first mortgage payment a month from today. So this amount is going to be compounded by the 0.5%, and as a decimal that's a 0.005.
Let's say that i is equal to the monthly interest.
Let's say n is equal to the number of months that we're dealing with. And then we're going to set p is equal to your monthly payment, your monthly mortgage payment. Some of which is interest, some of which is principle, but it's the same amount you're going to pay every month to pay down that loan plus interest.
You're going to have n parentheses.
And after you've done this n times, that is all going to be equal to 0. So my question, the one that I'm essentially setting up in this video, is how do we solve for p? You know if we know the loan amount, if we know the monthly interest rate, if we know the number of months, how do you solve for p?
Well then you start with your loan amount. It compounds for one month. You make your payment.
And there are ways to figure out the sums of geometric series for arbitrary ends.
As I promised at the beginning of the video this would be an application of a geometric series. It's equal to the sum of 1 over 1 plus i to the, well I'll use some other letter here, to the j from j is equal to 1. This is to the one power you could view this is to the first power to j is equal to n.
All of that over 1 minus r. Now if we're trying to solve for p you multiply both sides by the inverse of this, and you get p is equal to your loan amount times the inverse of that. I'm doing it in pink, because it's the inverse.
So r is 1 over 1 plus i. So let's take 1 divided by 1 plus i so plus 0.005.
So 0.995 that's what our r is equal to. Let me write that down, 0.995. Now this calculator doesn't store variables, so I'll just write that down here.
Let's multiply our loan amount that's $200,000 times 1 minus r, so 1 minus 0.995 divided by r which is 0.995 minus 0.995 to the of the-- now n is 360 months, so it's going to be 360 plus 1 to the 361 power, something I could definitely not do in my head, and then I close the parentheses, and my final answer is roughly $1,200. Actually if you do it with the full precision you get a little bit lower than that, but this is going to be roughly $1,200. So just like that, we were able to figure out our actual mortgage payment.
To be able to solve this, it'll be helpful to go back and take a good look at the algorithm. There's really two little blocks of things that are going on. For each node, we check all of its neighbors and once you add that up over all possible nodes whether all the neighbors of all the nodes, that's (M), so it's constant work for each of those edges.
So what are the students going to be doing when they meet up once a week? They're going to be presenting their lessons learned, and they're going to be presenting in front of their entire peers. Now, you'll be sitting in the back of the room, both the facilitators and the mentors, and critiquing what they've learned.
So, I'll start with this: a couple years ago, an event planner called me because I was going to do a speaking event. And she called, and she said,
"I'm really struggling with how to write about you on the little flyer." And I thought, "Well, what's the struggle?" And she said, "Well, I saw you speak, and I'm going to call you a researcher, I think, but I'm afraid if I call you a researcher, no one will come, because they'll think you're boring and irrelevant."
And I was like, "Why not 'magic pixie'?" (Laughter) I was like, "Let me think about this for a second."
When I was a young researcher, doctoral student, my first year, I had a research professor who said to us, "Here's the thing, if you cannot measure it, it does not exist." And I thought he was just sweet-talking me.
Well, you know that situation where you get an evaluation from your boss, and she tells you 37 things that you do really awesome, and one "opportunity for growth?" (Laughter) And all you can think about is that opportunity for growth, right?
They talked about the willingness to say, "I love you" first ... the willingness to do something where there are no guarantees ... the willingness to breathe through waiting for the doctor to call after your mammogram. They're willing to invest in a relationship that may or may not work out. They thought this was fundamental.
This led to a little breakdown -- (Laughter) -- which actually looked more like this. (Laughter)
Because about five of my friends were like, "Wooo, I wouldn't want to be your therapist." (Laughter)
And so I said, "Here's the thing, I'm struggling." And she said, "What's the struggle?" And I said, "Well, I have a vulnerability issue.
(Laughter) "I just need some strategies." (Laughter) (Applause)
"It just is what it is." And I said, "Oh my God, this is going to suck." (Laughter)
Our job is to look and say, "You know what? You're imperfect, and you're wired for struggle, but you are worthy of love and belonging."
We're now going to learn how to go from mixed numbers to improper fractions and vice versa. So first a little bit of terminology. What is a mixed number?
So two times two is four plus one is five. So let's write that. It's two times two plus one, and that's going to be the new numerator.
Let's say I had four and two thirds. This is equal to -- so this is going to be all over three. We keep the denominator the same.
Well that equals three times four-- order of operations, you always do multiplication first, and that's actually the way I taught it-- how to convert this, anyway. three times four is twelve plus two is fourteen. So that equals fourteen over three. Let's do another one.
Let's say I had six and seventeen eighteenths. I gave myself a hard problem. Well, we just keep the denominator the same.
Well six times eighteen. Let's see, that's sixty plus forty-eight it's one hundred eight, so that equals one hundred eight plus seventeen. All that over eighteen.
One hundred eight plus seventeen is equal to one hundred twenty-five over eighteen. So, six and seventeen eighteenths is equal to one hundred twenty-five over eighteen. Let's do a couple more.
So let's say two and one fourth. If we use the-- I guess you'd call it a system that I just showed you-- that equals four times two plus one over four.
Well that equals, four times two is eight plus one is nine. Nine over four. I want to give you an intuition for why this actually works.
So two and one fourth, let's actually draw that, see what it looks like. So let's put this back into kind of the pie analogy. So that's equal to one pie.
Two and one fourth, and ignore this, this is nothing. It's not a decimal point-- actually, let me erase it so it doesn't confuse you even more. So go back to the pieces of the pie.
Two and one fourth is the same thing as nine fourths. And this will work with any fraction. So let's go the other way.
Four times five is twenty. And the remainder is three. So twenty-three over five, we can say that's equal to four, and in the remainder, three over five.
Let's say, seventeen over eight. What does that equal as a mixed number? You can actually do this in your head, but I'll write it out just so you don't get confused.
Eight goes into seventeen two times.
Two times eight is sixteen. Seventeen minus sixteen is one. Remainder, one.
So, seventeen over eight is equal to two-- that's this two-- and one eighth. Right? Because we have one eight left over.
Five minus four is one, so the remainder is one, and that's what we use here. And of course, we keep the denominator the same. So five halves equals two and one half.
If you remember in our last slide, one of the choices was whether you were using physical or virtual distribution channels. Let's take a look at virtual channels, which are not only the web but also might include iPhone apps or the Cloud as well. The first choice might be dedicated e-commerce.
Zynga, which is a video game company, uses predominantly Facebook as its platform. And then finally flash sales. Examples include Groupon and Living Social.
Let's say I had the reaction where I had some copper ions. They have a positive charge of 2.
It's an aqueous solution. There could be some other negative ions in that solution. Actually we could talk about that in a little bit.
But we know that when you have these ions in solution, they all disassociate. So you just have to know you have a bunch of ions just floating around in water. There could be some other negative ones to neutralize the entire solution, but let's just worry about the positive ones for now.
And what happens is that they essentially switch places. The copper wants to jump out of your aqueous solution. I should probably draw this.
Let me draw it. This is my solution.
The Pythagorian philosopher Plato hinted enigmatically that there was a golden key that unified all of the mysteries of the universe. It is this golden key that we will return to time and again throughout our exploration. The golden key is the intelligence of the logos, the source of the primordial om.
The study of patterns in nature is not something that is very familiar in the West, but in ancient China, this science was known as "Li." Li reflects the dynamic order and pattern in nature. But it is not pattern thought of as something static, frozen or unchanging, like a mosaic.
"beauty is a manifestation of secret natural laws which otherwise would have been hidden from us forever." In this sense, everything in nature is alive, self-organizing. When higher voltage is used the fractal branching becomes even more obvious.
But in Chinese, Ayurvedic and Tibetan medicine the energy meridians are an essential component to understanding how the body functions. The "nadis," or energy meridians form tree-like structures. A post mortem examination will not reveal the chakras or the nadis, but that does not mean they do not exist.
The ancient concept of the "hara" is represented by a yinyang or spiral swirl. It is the power center located within the belly below the navel.
Hara means literally sea or ocean of energy. In China, the hara is called the lower dantien. In many forms of Asian martial arts, the warrior with strong hara is said to be unstoppable.
To blossom into the unique multi-faceted being you were designed to be. "Ida"-the feminine or moon channel is connected to the right brain and "pingala" the masculine or sun channel is connected to the left brain. When these two channels are in balance, energy flows up a third channel,
The word "chakra" is an ancient Sanskrit word meaning energy wheel. Kundalini is nothing less than the primordial spiral that dances your human life into existence. It is a different order of energy than we normally understand.
This spiral is the link between our inner worlds and our outer worlds.
On today's lecture, we're going to cover value proposition. What is it you're building and for who? What pains and gains are you creating for what customer segments?
"Oh that's another fancy word that says is what I'm building needed or wanted or passionately desired by a set of customers on the other end? And if I don't have that, then the good news about the customer development process is it allows us to keep searching without going out of business and so what you'll find is we'll be iterating back and forth doing things called pivots and iterations as we kind of discover what customers really want versus what we think we're building for them.
If you remember I said engineering was doing waterfall development. Waterfall development is just a step by step process that says marketing rights are requirements of what the product should do. Engineering takes that and translates that into features.
Let's add 536 to 398, and we're going to do it two different ways so you really understand what this carrying is all about. So first, we'll do it in the more traditional way. We start in the "one"s place, we say "what's 6 plus 8?"
1 plus 3 plus 9 is equal to 13. Now we have to remind ourselves that this is thirteen 10s. Or another way of thinking about it, this is three 10s and one hundred.
 We're asked how many inches are in 4 and 1/2 yards? Let me write that down.
4 and 1/2 yards. Now, whenever we're dealing with fractions and we're going to multiply and divide by fractions, it really complicates the issue to have a mixed number. So right from the get go, I want to turn this into an improper fraction.
4 is the same thing as 8/2. That's the same thing as 4. And then you have that plus 1/2.
2 times 4 is 8, 8 plus 1 is 9. So 4 and 1/2 is the same thing as 9/2.
So 4 and 1/2 yards is the same thing as-- let me write it over here-- 9/2. yards. Now, we want to convert this into inches. Just so we can take this in baby steps, maybe we convert this into feet first, and then once we have it in feet, then we can convert it into inches.
There are 3 feet per yard. And if we were to multiply 9/2 yards times 3 feet, this yard would be in the numerator. It'd be divided by this yard, and they would cancel out, and we'd just be left with feet.
27/2 is 3 times 9/2. So now we have 27/2 feet, and now we want to convert this to inches. And we just have to remember there are 12 inches per yard.
27/2 feet, we're going to multiply it by 12 to get the number of inches. Since this is going to be times 12, and we'll make sure the dimensions work out:
12 inches per foot. And the feet and the foot, this is just the plural and the singular of the same word. It's the same dimension.
And before we multiply the 27 times 12 and then divide by 2, you immediately see, well, I can just divide 12 by 2, and 2 by 2, and it makes our computation simpler.
12 divided by 2 is 6, 2 divided by 2 is 1. It becomes 27 times 6 inches, and let's figure out what that is.
27 times 6.
7 times 6 is 42.
2 times 6 is 12, plus 4 is 16. This is equal to 162 inches, which makes sense.
4 and 1/2 yards, that gets us to this number right here:
27 divided by 2 is 13 and 1/2 feet. You multiply that by 12, it makes sense. You're going to have a bunch of inches.
162 inches.
 We're on problem 48. It says if x squared is added to x, the sum is 42.
So we could write this as x squared plus x minus 42 is equal to 0. And let's think. What two numbers when I add them equal 1, and when I multiply them equal minus 42?
Let's see, we're on problem 50. Let me see, problem 50. I'll copy and paste 50 and 51.
16. OK.
8 and 2. Well they're going to have to be different signs. But I have a positive one here, so whichever number's
Leanne correctly solved the equation x squared plus 4x equals 6 by completing the square. Which equation is part of her solution? OK, so the same thing. x squared plus 4x.
Square a lot of binomials and see for yourself that that's always going to be the case. Anyway, so this is x plus 2 squared. That's going to be equal to-- 6 plus 4 is equal to 10.
I think we have time for one more. One more problem, problem 52. Copied it and now I have pasted it.
2x times x is 2x squared. Now that wouldn't be completely obvious if they didn't already tell us that we could factor this. You might have to use a quadratic equation or something.
So plus 2b plus ax plus ab. 2x squared. OK, now can do pattern matching.
All right. Initially we have--I cut 9. So these are the cuts that I made and just to show that it's still connected.
Firstly we'll need to update our parseAtlastDefinition function to take into account if a sprite has been trimmed, using this data to modify the corner x and corner y offset values. This is important because if you recall the coordinate system of the canvas will place an image according to its top left corner. Well, the trimming process in texture picker can move the top left corner to the new trimmed location.
So let's take a look at the channel economics. In other words, how are we going to make money? So let's take a look at a direct sales example.
Big Θ is just one of a bunch of different functions that we can define, and there's a set that essentially corresponds to all the different ways you might want to compare a function. If f(n) is in little o(g(n)), that's kind of like saying f(n) is strictly less than g(n). It grows less slowly asymptotically.
F(n) is in O(g(n))--there's our friend O--that's really like saying f(n) ≤ g(n). It might grow as fast as g(n), but it might be small.
Θ is the one we just looked at, which kind of like equality--they grow roughly at the same rate.
Ω--f(n) is in Ω(g(n)) means that it is an upper bound.
F(n) is bigger than or equal to g(n).
G(n) is a lower bound on f(n).
The ω, analogously, is kind of like strictly greater than.
Welcome back. We're doing the last part of Problem 1 of the 2008 Calculus BC exam. And I'll repeat the problem.
So we know this the height, sorry, the width along the surface of this cross section is going to be the difference between this function and this function, right? So if I were to draw, let me see if I can, so this is that same cross section, it's the width along the top, I know I'm confusing you, is going to be this function minus this function. It's going to be sine of pi x minus x to the third minus 4x.
And it noticed, it is calculating. And our answer is 8.37, I think, is a fair answer. So the volume this time, the volume of the pond, is equal to 8.37.
One of my favorite parts of my job at the Gates Foundation is that I get to travel to the developing world, and I do that quite regularly. And when I meet the mothers in so many of these remote places, I'm really struck by the things that we have in common.
"We're trying to deliver condoms to people or vaccinations," you know, Coke's success kind of stops and makes you wonder: how is it that they can get Coke to these far-flung places? If they can do that, why can't governments and NGOs do the same thing? And I'm not the first person to ask this question.
Coke's success is relevant, because if we can analyze it, learn from it, then we can save lives. So that's why I took a bit of time to study Coke. And I think there are really three things we can take away from Coca-Cola.
Let's look at the development side. What is it that governments and NGOs can learn from Coke? Governments and NGOs need to tap into that local entrepreneurial talent as well, because the locals know how to reach the very hard-to-serve places, their neighbors, and they know what motivates them to make change.
Now, think about how this can change people's lives. Health extension workers can help with so many things, whether it's family planning, prenatal care, immunizations for the children, or advising the woman to get to the facility on time for an on-time delivery. That is having real impact in a country like Ethiopia, and it's why you see their child mortality numbers coming down 25 percent from 2000 to 2008.
The third component of Coke's success is marketing. Ultimately, Coke's success depends on one crucial fact and that is that people want a Coca-Cola. Now the reason these micro-entrepreneurs can sell or make a profit is they have to sell every single bottle in their pushcart or their wheelbarrow.
Coke's global campaign slogan is "Open Happiness." But they localize it. And they don't just guess what makes people happy; they go to places like Latin America and they realize that happiness there is associated with family life.
"Wavin' Flag" by a Somali hip hop artist.
(Video) K'Naan: ♫ Oh oh oh oh oh o-oh ♫ ♫ Oh oh oh oh oh oh oh oh oh oh ♫ ♫ Oh oh oh oh oh o-oh ♫ ♫ Oh oh oh oh oh oh oh oh o-oh ♫ ♫Give you freedom, give you fire♫ ♫ Give you reason, take you higher ♫ ♫ See the champions take the field now ♫ ♫ You define us, make us feel proud ♫ ♫ In the streets our heads are lifted ♫ ♫ As we lose our inhibition ♫ ♫ Celebration, it's around us ♫ ♫ Every nation, all around us ♫ Melinda French Gates: It feels pretty good, right?
"I'd Like to Teach the World to Sing," that also went number one on the pop charts. Both songs have something in common: that same appeal of celebration and unity. So how does health and development market?
And I think we make a fundamental mistake -- we make an assumption, that we think that, if people need something, we don't have to make them want that. And I think that's a mistake. And there's some indications around the world that this is starting to change.
(Laughter) But what does marketing really entail that would make a sanitation solution get a result in diarrhea? Well, you work with the community.
(Laughter) I'm not kidding. Women are refusing to marry men without toilets.
(Laughter) Now, it's not just a funny headline -- it's innovative. It's an innovative marketing campaign.
In 2009, we're down to 1,600 cases. Well how did that happen? Let's look at a country like India.
By August 30th, a genetic test was done, and we knew what strain of polio Shriram had. Now it could have come from one of two places. It could have come from Nepal, just to the north, across the border, or from Jharkhand, a state just to the south.
"If you see paralysis, take your child to the doctor or get your child vaccinated." We have a problem with marketing in the donor community. The G8 nations have been incredibly generous on polio over the last 20 years, but we're starting to have something called polio fatigue and that is that the donor nations aren't willing to fund polio any longer.
And so if we can learn lessons from the innovators in every sector, then in the future we make together, that happiness can be just as ubiquitous as Coca-Cola. Thank you.
(Applause)
 In the completing the square video I kept saying that all the quadratic equation is completing the square as kind of a short cut of completing square. And I was under the impression that I had done this proof already but now I realize that I haven't.
So let me prove the quadratic equation to you, by completing the square. So let's say I have a quadratic equation. I guess a quadratic equation is actually what you're trying to solve, and what a lot of people call the quadratic equation is actually the quadratic formula.
So I get x squared plus b/a x is equal to-- you have to divide both sides by a --minus c/a. Now we are ready to complete the square. What was completing the square?
What you do is you say well this b/a, this corresponds to the 2a term, so a is going to be half of this, is going to be half of this coefficient. That would be the a. And then what I need to add is a squared.
So plus b/2a squared. And now I have this left hand side of the equation in the form that it is the square of an expression that is x plus something. And what is it?
So this is the same thing as x plus b over 2a everything squared, and then that equals-- let's see if we can simplify this or make this a little bit cleaner --that equals-- See, if I were to have a common denominator-- I'm just doing a little bit of algebra here --see, when I square this it's going to be 4a squared-- let me let me write this.
Well it's just 2a, right? 2a. And now what do we do?
Congress, distinguished guests, and fellow Americans: Last month, I went to Andrews Air
(Applause.)
Americans fighting in Iraq.
(Applause.) For the first time in two decades, Osama bin Laden is not a threat to this country.
(Applause.) Most of al Qaeda's top lieutenants have been defeated. The Taliban's momentum has been broken, and some troops in Afghanistan have begun to come home.
Imagine what we could accomplish if we followed their example.
A country that leads the world in educating its people. An America that attracts a new generation of high-tech manufacturing and high-paying jobs. A future where we're in control of our own energy, and our security and prosperity aren't so tied to unstable parts of the world.
We can do this. I know we can, because we've done it before. At the end of World
War Il, when another generation of heroes returned home from combat, they built the strongest economy and middle class the world has ever known.
(Applause.) My grandfather, a veteran of Patton's Army, got the chance to go to college on the GI Bill. My grandmother, who worked on a bomber assembly line, was part of a workforce that turned out the best products on Earth.
We can either settle for a country where a shrinking number of people do really well while a growing number of Americans barely get by, or we can restore an economy where everyone gets a fair shot, and everyone does their fair share, and everyone plays by the same set of rules.
(Applause.)
Long before the recession, jobs and manufacturing began leaving our shores.
Folks at the top saw their incomes rise like never before, but most hardworking Americans struggled with costs that were growing, paychecks that weren't, and personal debt that kept piling up.
We learned that mortgages had been sold to people who couldn't afford or understand them.
And we lost another 4 million before our policies were in full effect.
In the last 22 months, businesses have created more than 3 million jobs.
(Applause.)
American manufacturers are hiring again, creating jobs for the first time since the late 1990s. Together, we've agreed to cut the deficit by more than $2 trillion.
Street accountable, so a crisis like this never happens again.
The state of our Union is getting stronger. And we've come too far to turn back now. As long as I'm President, I will work with anyone in this chamber to build on this momentum.
But I intend to fight obstruction with action, and I will oppose any effort to return to the very same policies that brought on this economic crisis in the first place.
No, we will not go back to an economy weakened by outsourcing, bad debt, and phony financial profits. Tonight, I want to speak about how we move forward, and lay out a blueprint for an economy that's built to last -- an economy built on American manufacturing, American energy, skills for
American manufacturing. On the day I took office, our auto industry was on the verge of collapse. Some even said we should let it die.
Today, General Motors is back on top as the world's number-one automaker.
U.S. than any major car company. Ford is investing billions in U.S. plants and factories.
And tonight, the American auto industry is back.
(Applause.) What's happening in Detroit can happen in other industries. It can happen in Cleveland and Pittsburgh and Raleigh.
(Applause.)
Today, for the first time in 15 years, Master Lock's unionized plant in Milwaukee is running at full capacity.
(Applause.)
So we have a huge opportunity, at this moment, to bring manufacturing back. But we have to seize it. Tonight, my message to business leaders is simple:
Ask yourselves what you can do to bring jobs back to your country, and your country will do everything we can to help you succeed. (Applause.)
Right now, companies get tax breaks for moving jobs and profits overseas. Meanwhile, companies that choose to stay in America get hit with one of the highest tax rates in the world. It makes no sense, and everyone knows it.
(Applause.)
Master Lock that decide to bring jobs home. (Applause.)
Second, no American company should be able to avoid paying its fair share of taxes by moving jobs and profits overseas.
(Applause.) From now on, every multinational company should have to pay a basic minimum tax. And every penny should go towards lowering taxes for companies that choose to stay here and hire here in America.
(Applause.)
Third, if you're an American manufacturer, you should get a bigger tax cut. If you're a high-tech manufacturer, we should double the tax deduction you get for making your products here. And if you want to relocate in a community that was hit hard when a factory left town, you should get help financing a new plant, equipment, or training for new workers.
(Applause.) So my message is simple. It is time to stop rewarding businesses that ship jobs overseas, and start rewarding companies that create jobs right here in America.
(Applause.)
We're also making it easier for American businesses to sell products all over the world. Two years ago, I set a goal of doubling U.S. exports over five years. With the bipartisan trade agreements we signed into law, we're on track to meet that goal ahead of schedule.
Soon, there will be new cars on the streets of Seoul imported from Detroit, and Toledo, and Chicago. (Applause.)
I will go anywhere in the world to open new markets for American products. And I will not stand by when our competitors don't play by the rules. We've brought trade cases against China at nearly twice the rate as the last administration -- and it's made a difference.
(Applause.) Over a thousand Americans are working today because we stopped a surge in Chinese tires. But we need to do more. It's not right when another country lets our movies, music, and software be pirated.
(Applause.) There will be more inspections to prevent counterfeit or unsafe goods from crossing our borders. And this Congress should make sure that no foreign company has an advantage over American manufacturing when it comes to accessing financing or new markets like Russia. Our workers are the most productive on Earth, and if the playing field is level, I promise you -- America will always win.
(Applause.)
I also hear from many business leaders who want to hire in the United States but can't find workers with the right skills. Growing industries in science and technology have twice as many openings as we have workers who can do the job. Think about that -- openings at a time when millions of Americans are looking for work.
lead directly to a job.
My administration has already lined up more companies that want to help. Model partnerships between businesses like Siemens and community colleges in places
like Charlotte, and Orlando, and Louisville are up and running. Now you need to give more community colleges the resources they need to become community career centers -- places that teach people skills that businesses are looking for right now, from data management to high-tech manufacturing. And I want to cut through the maze of confusing training programs, so that from now on, people like Jackie have one program, one website, and one place to go for all the information and help that they need.
(Applause.)
These reforms will help people get jobs that are open today. But to prepare for the jobs of tomorrow, our commitment to skills and education has to start earlier. For less than 1 percent of what our nation spends on education each year, we've convinced nearly every state in the country to raise their standards for teaching and learning -- the first time that's happened in a generation.
Most teachers work tirelessly, with modest pay, sometimes digging into their own pocket for school supplies -- just to make a difference. So instead of bashing them, or defending the status quo, let's offer schools a deal.
Give them the resources to keep good teachers on the job, and reward the best ones. (Applause.) And in return, grant schools flexibility: to teach with creativity and passion; to stop teaching to the test; and to replace teachers who just aren't helping kids learn.
That's a bargain worth making.
(Applause.) We also know that when students don't walk away from their education, more of them walk the stage to get their diploma. When students are not allowed to drop out, they do better.
So tonight, I am proposing that every state -- every state -- requires that all students stay in high school until they graduate or turn 18.
(Applause.)
At a time when Americans owe more in tuition debt than credit card debt, this Congress needs to stop the interest rates on student loans from doubling in July.
(Applause.) Extend the tuition tax credit we started that saves millions of middle-class families thousands of dollars, and give more young people the chance to earn their way through college by doubling the number of work-study jobs in the next five years.
(Applause.) Of course, it's not enough for us to increase student aid. We can't just keep subsidizing skyrocketing tuition; we'll run out of money.
States also need to do their part, by making higher education a higher priority in their budgets. And colleges and universities have to do their part by working to keep costs down. Recently, I spoke with a group of college presidents who've done just that.
We should be working on comprehensive immigration reform right now.
But if election-year politics keeps Congress from acting on a comprehensive plan, let's at least agree to stop expelling responsible young people who want to staff our labs, start new businesses, defend this country. I will sign it right away.
(Applause.)
You see, an economy built to last is one where we encourage the talent and ingenuity of every person in this country. That means women should earn equal pay for equal work.
(Applause.) It means we should support everyone who's willing to work, and every risk-taker and entrepreneur who aspires to become the next Steve Jobs. After all, innovation is what America has always been about.
Most new jobs are created in start-ups and small businesses. So let's pass an agenda that helps them succeed. Tear down regulations that prevent aspiring entrepreneurs from getting the financing to grow.
So put them in a bill, and get it on my desk this year.
(Applause.) Innovation also demands basic research. Today, the discoveries taking place in our federally financed labs and universities could lead to new treatments that kill cancer cells but leave healthy ones untouched.
Over the last three years, we've opened millions of new acres for oil and gas exploration, and tonight, I'm directing my administration to open more than 75 percent of our potential offshore oil and gas resources.
Right now -- right now -- American oil production is the highest that it's been in eight years. That's right -- eight years. Not only that -- last year, we relied less on foreign oil than in any of the past 16 years.
(Applause.) But with only 2 percent of the world's oil reserves, oil isn't enough. This country needs an all-out, all-of-the-above strategy that develops every available source of
American energy.
(Applause.) A strategy that's cleaner, cheaper, and full of new jobs. We have a supply of natural gas that can last America nearly 100 years.
(Applause.) And my administration will take every possible action to safely develop this energy. Experts believe this will support more than 600,000 jobs by the end of the decade.
And I'm requiring all companies that drill for gas on public lands to disclose the chemicals they use. (Applause.) Because America will develop this resource without putting the health and safety of our citizens at risk.
The development of natural gas will create jobs and power trucks and factories that are cleaner and cheaper, proving that we don't have to choose between our environment and our economy. (Applause.)
And by the way, it was public research dollars, over the course of 30 years, that helped develop the technologies to extract all this natural gas out of shale rock -- reminding us that government support is critical in helping businesses get new energy ideas off the ground.
(Applause.) Now, what's true for natural gas is just as true for clean energy.
In three years, our partnership with the private sector has already positioned America to be the world's leading manufacturer of high-tech batteries. Because of federal investments, renewable energy use has nearly doubled, and thousands of Americans have jobs because of it.
I will not walk away from workers like Bryan.
I will not cede the wind or solar or battery industry to China or Germany because we refuse to make the same commitment here. We've subsidized oil companies for a century. That's long enough.
(Applause.) It's time to end the taxpayer giveaways to an industry that rarely has been more profitable, and double-down on a clean energy industry that never has been more promising.
Create these jobs.
(Applause.) We can also spur energy innovation with new incentives.
The differences in this chamber may be too deep right now to pass a comprehensive plan to fight climate change. But there's no reason why Congress shouldn't at least set a clean energy standard that creates a market for innovation. So far, you haven't acted.
Navy purchasing enough capacity to power a quarter of a million homes a year.
Of course, the easiest way to save money is to waste less energy.
Send me a bill that creates these jobs.
(Applause.) Building this new energy future should be just one part of a broader agenda to repair America's infrastructure. So much of America needs to be rebuilt.
Take the money we're no longer spending at war, use half of it to pay down our debt, and use the rest to do some nation-building right here at home.
(Applause.) There's never been a better time to build, especially since the construction industry was one of the hardest hit when the housing bubble burst. Of course, construction workers weren't the only ones who were hurt.
(Applause.) No more red tape.
(Applause.)
Millions of Americans who work hard and play by the rules every day deserve a government and a financial system that do the same.
That's why we need smart regulations to prevent irresponsible behavior.
They make the free market work better.
(Applause.) I've ordered every federal agency to eliminate rules that don't make sense. We've already announced over 500 reforms, and just a fraction of them will save business and citizens more than $10 billion over the next five years.
Now, I'm confident a farmer can contain a milk spill without a federal agency looking over his shoulder.
I guess it was worth crying over spilled milk.
(Laughter and applause.)
But I will not back down from making sure an oil company can contain the kind of oil spill we saw in the Gulf two years ago.
I will not back down from protecting our kids from mercury poisoning, or making sure that our food is safe and our water is clean. I will not go back to the days when health insurance companies had unchecked power to cancel your policy, deny your coverage, or charge women differently than men.
And I will not go back to the days when Wall Street was allowed to play by its own set of rules. The new rules we passed restore what should be any financial system's core purpose: Getting funding to entrepreneurs with the best ideas, and getting loans to responsible families who want to buy a home, or start a business, or send their kids to college.
You're required to write out a "living will" that details exactly how you'll pay the bills if you fail - because the rest of us are not bailing you out ever again.
And if you're a mortgage lender or a payday lender or a credit card company, the days of signing people up for products they can't afford with confusing forms and deceptive practices -- those days are over.
Today, American consumers finally have a watchdog in Richard Cordray with one job:
To look out for them. We'll also establish a Financial Crimes Unit of highly trained investigators to crack down on large-scale fraud and protect people's investments. Some financial firms violate major anti-fraud laws because there's no real penalty for being a repeat offender.
And tonight, I'm asking my Attorney General to create a special unit of federal prosecutors and leading state attorney general to expand our investigations into the abusive lending and packaging of risky mortgages that led to the housing crisis. This new unit will hold accountable those who broke the law, speed assistance to homeowners, and help turn the page on an era of recklessness that hurt so many Americans. Now, a return to the American values of fair play and shared responsibility will help protect our people and our economy.
Right now, our most immediate priority is stopping a tax hike on 160 million working Americans while the recovery is still fragile.
People cannot afford losing $40 out of each paycheck this year. There are plenty of ways to get this done. So let's agree right here, right now:
Pass the payroll tax cut without delay.
When it comes to the deficit, we've already agreed to more than $2 trillion in cuts and savings. But we need to do more, and that means making choices. Right now, we're poised to spend nearly $1 trillion more on what was supposed to be a temporary tax break for the wealthiest 2 percent of Americans.
The American people know what the right choice is. So do I. As I told the Speaker this summer, I'm prepared to make more reforms that rein in the long-term costs of Medicare and Medicaid, and strengthen Social Security, so long as those programs remain a guarantee of security for seniors.
But in return, we need to change our tax code so that people like me, and an awful lot of members of Congress, pay our fair share of taxes.
If you make more than $1 million a year, you should not pay less than 30 percent in taxes. And my Republican friend Tom Coburn is right: Washington should stop subsidizing millionaires.
On the other hand, if you make under $250,000 a year, like 98 percent of American families, your taxes shouldn't go up. You're the ones struggling with rising costs and stagnant wages. You're the ones who need relief.
That's an America built to last.
(Applause.) Now, I recognize that people watching tonight have differing views about taxes and debt, energy and health care. But no matter what party they belong to, I bet most Americans are thinking the same thing right about now:
I will sign it tomorrow.
(Applause.) Let's limit any elected official from owning stocks in industries they impact. Let's make sure people who bundle campaign contributions for Congress can't lobby Congress, and vice versa -- an idea that has bipartisan support, at least outside of Washington. Some of what's broken has to do with the way Congress does its business these days.
A simple majority is no longer enough to get anything -- even routine business -- passed through the Senate. (Applause.) Neither party has been blameless in these tactics. Now both parties should put an end to it.
(Applause.)
For starters, I ask the Senate to pass a simple rule that all judicial and public service nominations receive a simple up or down vote within 90 days.
(Applause.) The executive branch also needs to change.
Too often, it's inefficient, outdated and remote. (Applause.) That's why I've asked this Congress to grant me the authority to consolidate the federal bureaucracy, so that our government is leaner, quicker, and more responsive to the needs of the American people.
(Applause.)
Finally, none of this can happen unless we also lower the temperature in this town. We need to end the notion that the two parties must be locked in a perpetual campaign of mutual destruction; that politics is about clinging to rigid ideologies instead of building consensus around common-sense ideas. I'm a Democrat.
(Applause.) That's why my education reform offers more competition, and more control for schools and states. That's why we're getting rid of regulations that don't work. That's why our health care law relies on a reformed private market, not a government program.
Because when we act together, there's nothing the United States of America can't achieve.
That's the lesson we've learned from our actions abroad over the last few years. Ending the Iraq war has allowed us to strike decisive blows against our enemies.
From Pakistan to Yemen, the al Qaeda operatives who remain are scrambling, knowing that they can't escape the reach of the United States of America.
(Applause.)
From this position of strength, we've begun to wind down the war in Afghanistan. Ten thousand of our troops have come home. Twenty-three thousand more will leave by the end of this summer.
This transition to Afghan lead will continue, and we will build an enduring partnership with Afghanistan, so that it is never again a source of attacks against America.
(Applause.) As the tide of war recedes, a wave of change has washed across the Middle East and North Africa, from Tunis to Cairo; from Sana'a to Tripoli. A year ago, Qaddafi was one of the world's
And in Syria, I have no doubt that the Assad regime will soon discover that the forces of change cannot be reversed, and that human dignity cannot be denied.
(Applause.) How this incredible transformation will end remains uncertain. But we have a huge stake in the outcome.
America is determined to prevent Iran from getting a nuclear weapon, and I will take no options off the table to achieve that goal.
(Applause.) But a peaceful resolution of this issue is still possible, and far better, and if Iran changes course and meets its obligations, it can rejoin the community of nations. The renewal of American leadership can be felt across the globe.
-- and I mean ironclad -- to Israel's security has meant the closest military cooperation between our two countries in history.
We've made it clear that America is a Pacific power, and a new beginning in Burma has lit a new hope. From the coalitions we've built to secure nuclear materials, to the missions we've led against hunger and disease; from the blows we've dealt to our enemies, to the enduring power of our moral example, America is back. Anyone who tells you otherwise, anyone who tells you that America is in decline or that our influence has waned, doesn't know what they're talking about.
(Applause.) That's not the message we get from leaders around the world who are eager to work with us. That's not how people feel from Tokyo to Berlin, from Cape Town to Rio, where opinions of America are higher than they've been in years. Yes, the world is changing.
But America remains the one indispensable nation in world affairs -- and as long as I'm President, I intend to keep it that way.
That's why, working with our military leaders, I've proposed a new defense strategy that ensures we maintain the finest military in the world, while saving nearly half a trillion dollars in our budget. To stay one step ahead of our adversaries, I've already sent this Congress legislation that will secure our country from the growing dangers of cyber-threats.
(Applause.)
Above all, our freedom endures because of the men and women in uniform who defend it.
That includes giving them the care and the benefits they have earned -- which is why we've increased annual
VA spending every year I've been President.
(Applause.) And it means enlisting our veterans in the work of rebuilding our nation. With the bipartisan support of this Congress, we're providing new tax credits to companies that hire vets. Michelle and Jill Biden have worked with American businesses to secure a pledge of 135,000 jobs for veterans and their families.
And tonight, I'm proposing a Veterans Jobs Corps that will help our communities hire veterans as cops and firefighters, so that America is as strong as those who defend her.
Those of us who've been sent here to serve can learn a thing or two from the service of our troops.
When you put on that uniform, it doesn't matter if you're black or white; Asian, Latino, Native American; conservative, liberal; rich, poor; gay, straight.
When you're marching into battle, you look out for the person next to you, or the mission fails.
When you're in the thick of the fight, you rise or fall as one unit, serving one nation, leaving no one behind. One of my proudest possessions is the flag that the SEAL Team took with them on the mission to get bin Laden. On it are each of their names.
Some may be Republicans. But that doesn't matter. Just like it didn't matter that day in the
Bob Gates -- a man who was George Bush's defense secretary -- and Hillary Clinton -- a woman who ran against me for president.
No one thought about themselves. One of the young men involved in the raid later told me that he didn't deserve credit for the mission. It only succeeded, he said, because every single member of that unit did their job -- the pilot who landed the helicopter that spun out of control; the translator who kept others from entering the compound; the troops who separated the women and children from the fight; the SEALs who charged up the stairs.
Each time I look at that flag, I'm reminded that our destiny is stitched together
As long as we are joined in common purpose, as long as we maintain our common resolve, our journey moves forward, and our future is hopeful, and the state of our Union will always be strong.
I'm going to start here. This is a hand-lettered sign that appeared in a mom and pop bakery in my old neighborhood in Brooklyn a few years ago. The store owned one of those machines that can print on plates of sugar.
"You know what, we're getting out of that business. If you're an amateur, you don't have access to our machine anymore. If you want a printed sugar birthday cake, you have to use one of our prefab images -- only for professionals."
"Like handing out water that wasn't wet." Bits are copyable. That's what computers do.
So what PlPA and SOPA risk doing is taking a centuries-old legal concept, innocent until proven guilty, and reversing it -- guilty until proven innocent. You can't share until you show us that you're not sharing something we don't like. Suddenly, the burden of proof for legal versus illegal falls affirmatively on us and on the services that might be offering us any new capabilities.
"We'd prefer not to do that," says the content industries. And what they want is not to have to do that. They don't want legal distinctions between legal and illegal sharing.

(applause) Hi honey. What is wrong? You look worried.
I'I walk from here. Are you sure? Yeah, I'm sure.
Demitry, is jake. Yeah. LA.
Demitry, welcome to the States! Don't screw around. This guy is crazy.
Wakey, wakee. Do you know who we are. Do you know what we're doing here.
Demitry! I tried to save you kid but you don't want to listen. Just let me go.
I'e got the person that I will spend my life with it. Well, we are both young and hopefully we will get along together well, because we need more experience. But I'm so happy to be here, I have only you here.
I'm gonna pray to God that our marriage is gonna last forever and we are going to spend to death and die in the same day. Wow! I hope so too, in the dame day!
I'm out. Demitry, What did you got? Full house.
Demitry, a little bit more poker won't kill you. A little bit? We're playing for one or two hours!
What else we're gonna do? We have people to kill. Let't get to work.
Come on in. We have a mess to clean. Thank you Jake for not betraying me and taking care of Demitry.
All right, what we're going to talk about next is the idea that there're are some problems such that if we could solve them fast, we could solve all problems in NP fast, and we call those problems the NP hard problems. I don't find that to be a particularly useful name, but it's the name that everybody uses so I will use it as well. How can we say that some problem X is at least this hard, at least within polynomial factors, as some other problem Y.
In fact, that's maybe what we mean by saying that X is at least as hard as Y that we can use as solution to X to solve Y. The basic picture that you can have in your head is something like this, Imagine that we want to solve an instance of problem Y, we can imagine building a solution algorithm, an algorithm for Y, that what happen inside is instance of problem Y gets transformed in some way between instance of problem X or may be multiple instances of problem X.
Let's think about what functions really do, and then we'll think about the idea of an inverse of a function. So let's start with a pretty straightforward function. Let's say f of x is equal to 2x plus 4.
And we can call that the range. There are more formal ways to talk about this, and there's a much more rigorous discussion of this later on, especially in the linear algebra playlist, but this is all the different values I can take on. So if I take the number 2 from our domain, I input it into the function, we're getting mapped to the number 8.
Now, all this seems very abstract and difficult. What you'll find is it's actually very easy to solve for this inverse of f, and I think once we solve for it, it'll make it clear what I'm talking about. That the function takes you from 2 to 8, the inverse will take us back from 8 to 2.
And you could see, you have the function and its inverse, they're reflected about the line y is equal to x. And hopefully, that makes sense here. Because over here, on this line, let's take an easy example.
WHERE DOES IRRlTATlON OCCUR Each and every one of these... Each of these satsangs, each of these samayiks,
And the answer is rabbit. Tada! I figured that was a good animal to use for a magic trick and have it come out of the hat.
What I want you to think about is, imagine that we've got a graph with n nodes and m edges, and we're going to try to find out whether it's colorable well with k colors by turning it into a big formula like the one I just showed you. I want to know how many clauses are in the formula, and just to make that a bit more concrete a clause is the sort of thing that I got here in parenthesis, it's between the n's. We have a list of things that are combined and then there's an n and then there's more things that are combined and an n, so how many things are being ended together in the formula.
A town had a population of 11,256 in 1995. By 2010, the population in that town had increased by 4,312. Estimate the town's population in 2010 by first rounding these two numbers to the nearest hundred.
Instead of having 256, we're rounding up to 300. 300 is closer to 256 than 200 is. That's why we're rounding up to that.
1 is definitely less than 5, so we want to round down. So 312 is closer to 300. We round down to just a 3 here and these get zeroed out.
Back in New York, I am the head of development for a non-profit called Robin Hood. When I'm not fighting poverty, I'm fighting fires as the assistant captain of a volunteer fire company. Now in our town, where the volunteers supplement a highly skilled career staff, you have to get to the fire scene pretty early to get in on any action.
A recipe for oatmeal cookies calls for 2 cups of flour for every 3 cups of oatmeal. How much flour is needed for a big batch of cookies that uses 9 cups of oatmeal? So they tell us that we have 2 cups of flour.
You need 2 cups of flour for every 3 cups of oatmeal. Now, what we need to figure out is how much flour is needed for a big batch that uses 9 cups of oatmeal. We need to figure out how much.
The Highline is an old, elevated rail line that runs for a mile and a half right through Manhattan. And it was originally a freight line that ran down 10th Ave. And it became known as "Death Avenue" because so many people were run over by the trains that the railroad hired a guy on horseback to run in front, and he became known as the "West Side Cowboy."
So we said over a 20-year time period, the value to the city in increased property values and increased taxes would be about 250 million. That was enough. It really got the city behind it.
There's a point, you can stand here and see buildings by Frank Gehry, Jean Nouvel, Shigeru Ban, Neil Denari.
(Applause)
Climate change is already a heavy topic, and it's getting heavier because we're understanding that we need to do more than we are. We're understanding, in fact, that those of us who live in the developed world need to be really pushing towards eliminating our emissions. That's, to put it mildly, not what's on the table now.
(Laughter) But the technologies are getting better, and we're starting to really kind of crowdsource this navigation. And as we just heard earlier, of course, we're also learning how to put information on dumb objects.
"by stealing the future, selling it in the present and calling it GDP." And if we have another eight billion or seven billion, or six billion, even, people, living on a planet where their cities also steal the future, we're going to run out of future really fast.
(Applause)
Through Hardship to the Stars
It's easy to imagine skeins of historical causality there were many possible historical paths. Our ancestors walked from East Africa to Novaya Zemlya and Ayers Rock and Patagonia, they hunted elephants with stone spearpoints, they walked the Moon a decade after entering space. It is beyond our powers to predict the future.
So what does this mean, what can we conclude?
>> Fantastic. The solution for this is pretty straight forward, based upon what we've already seen. Firstly, we walk through all the tile set's inside of the map object that we've created.
CHAPTER 1 LEAVE IT TO JEEVES Jeeves--my man, you know--is really a most extraordinary chap. So capable.
You go up to them and say: "When's the next train for Melonsquashville, Tennessee?" and they reply, without stopping to think, "Two-forty-three, track ten, change at San Francisco."
"Jeeves," I said that evening. "I'm getting a check suit like that one of Mr. Byng's." "Injudicious, sir," he said firmly.
"Unsuitable for you, sir." Well, the long and the short of it was that the confounded thing came home, and I put it on, and when I caught sight of myself in the glass I nearly swooned.
Jeeves was perfectly right. I looked a cross between a music-hall comedian and a cheap bookie. Yet Monty had looked fine in absolutely the same stuff.
"Lincolnshire." I forget now how I got it, but it had the aspect of being the real, red-hot tabasco.
"Jeeves," I said, for I'm fond of the man, and like to do him a good turn when I can,
"if you want to make a bit of money have something on Wonderchild for the
'Lincolnshire.'" He shook his head. "I'd rather not, sir."
"I do not recommend it, sir. The animal is not intended to win. Second place is what the stable is after."
Still, you know what happened. Wonderchild led till he was breathing on the wire, and then Banana Fritter came along and nosed him out. I went straight home and rang for Jeeves.
"Very good, sir. I shall endeavour to give satisfaction." And he has, by Jove! I'm a bit short on brain myself; the old bean would appear to have been constructed more for ornament than for use, don't you know; but give me five minutes to talk the thing over with Jeeves, and I'm game to advise any one about anything.
And that's why, when Bruce Corcoran came to me with his troubles, my first act was to ring the bell and put it up to the lad with the bulging forehead.
"Leave it to Jeeves," I said. I first got to know Corky when I came to New York. He was a pal of my cousin Gussie, who was in with a lot of people down Washington
Chappies introduced me to other chappies, and so on and so forth, and it wasn't long before I knew squads of the right sort, some who rolled in dollars in houses up by the Park, and others who lived with the gas turned down mostly around Washington Square--artists and writers and so forth. Brainy coves.
Corky was one of the artists. A portrait-painter, he called himself, but he hadn't painted any portraits. He was sitting on the side-lines with a blanket over his shoulders, waiting for a chance to get into the game.
I'm a bit foggy as to what jute is, but it's apparently something the populace is pretty keen on, for Mr. Worple had made quite an indecently large stack out of it. Now, a great many fellows think that having a rich uncle is a pretty soft snap: but, according to Corky, such is not the case.
Corky's uncle was a robust sort of cove, who looked like living for ever. He was fifty-one, and it seemed as if he might go to par. It was not this, however, that distressed poor old Corky, for he was not bigoted and had no objection to the man going on living.
What Corky kicked at was the way the above Worple used to harry him.
Corky's uncle, you see, didn't want him to be an artist. He didn't think he had any talent in that direction. He was always urging him to chuck Art and go into the jute business and start at the bottom and work his way up.
Corky, moreover, believed in his future as an artist. Some day, he said, he was going to make a hit. Meanwhile, by using the utmost tact and persuasiveness, he was inducing his uncle to cough up very grudgingly a small quarterly allowance.
Corky used to go to him about once every three months and let him talk about American birds. Apparently you could do what you liked with old Worple if you gave him his head first on his pet subject, so these little chats used to make Corky's allowance all right for the time being.
Muriel Singer was one of those very quiet, appealing girls who have a way of looking at you with their big eyes as if they thought you were the greatest thing on earth and wondered that you hadn't got on to it yet yourself. She sat there in a sort of shrinking way, looking at me as if she were saying to herself, "Oh, I do hope this great strong man isn't going to hurt me." She gave a fellow a protective kind of feeling, made him want to stroke her hand and say, "There, there, little one!" or words to that effect.
Corky declined to cheer up. "You don't know him. Even if he did like Muriel he wouldn't admit it.
One of the rummy things about Jeeves is that, unless you watch like a hawk, you very seldom see him come into a room. He's like one of those weird chappies in India who dissolve themselves into thin air and nip through space in a sort of disembodied way and assemble the parts again just where they want them. I've got a cousin who's what they call a Theosophist, and he says he's often nearly worked the thing himself, but couldn't quite bring it off, probably owing to having fed in his boyhood on the flesh of animals slain in anger and pie.
Jeeves is a tallish man, with one of those dark, shrewd faces. His eye gleams with the light of pure intelligence.
"Jeeves, we want your advice." "Very good, sir." I boiled down Corky's painful case into a few well-chosen words. "So you see what it amount to, Jeeves.
"Perfectly, sir." "Well, try to think of something." "I have thought of something already, sir." "You have!" "The scheme I would suggest cannot fail of success, but it has what may seem to you a drawback, sir, in that it requires a certain financial outlay."
"He means," I translated to Corky, "that he has got a pippin of an idea, but it's going to cost a bit." Naturally the poor chap's face dropped, for this seemed to dish the whole thing. But I was still under the influence of the girl's melting gaze, and I saw that this was where I started in as a knight-errant. "You can count on me for all that sort of thing, Corky," I said.
"I would suggest, sir, that Mr. Corcoran take advantage of Mr. Worple's attachment to ornithology."
"How on earth did you know that he was fond of birds?" "It is the way these New York apartments are constructed, sir. Quite unlike our London houses.
"Oh! Well?" "Why should not the young lady write a small volume, to be entitled--let us say-- The Children's Book of American Birds, and dedicate it to Mr. Worple! A limited edition could be published at your expense, sir, and a great deal of the book would, of course, be given over to eulogistic remarks concerning Mr. Worple's own larger treatise on the same subject.
If I had half Jeeves's brain, I should have a stab, at being Prime Minister or something. "Jeeves," I said, "that is absolutely ripping! One of your very best efforts." "Thank you, sir."
I can't even write good letters." "Muriel's talents," said Corky, with a little cough "lie more in the direction of the drama, Bertie. I didn't mention it before, but one of our reasons for being a trifle nervous as to how Uncle Alexander will receive the news is that Muriel is in the chorus of that show Choose your Exit at the Manhattan.
"That's true," said Corky. "Sam Patterson would do it for a hundred dollars. He writes a novelette, three short stories, and ten thousand words of a serial for one of the all-fiction magazines under different names every month.
Muriel Singer was there, and we were talking of things in general when there was a bang at the door and the parcel was delivered. It was certainly some book. It had a red cover with a fowl of some species on it, and underneath the girl's name in gold letters.
Corky, I took it, was out telephoning. I went up and passed the time of day. "Well, well, well, what?"
"You're waiting for Corky, aren't you?" "Oh, I didn't understand. No, I'm not waiting for him." It seemed to roe that there was a sort of something in her voice, a kind of thingummy, you know.
"A row?" "A spat, don't you know--little misunderstanding--faults on both sides--er- -and all that sort of thing."
"Why, whatever makes you think that?" "Oh, well, as it were, what? What I mean is--I thought you usually dined with him before you went to the theatre." "I've left the stage now."
"Yes." "How perfectly topping! I wish you all kinds of happiness."
"Thank you, so much. Oh Alexander," she said, looking past me, "this is a friend of mine--Mr. Wooster."
I spun round. A chappie with a lot of stiff grey hair and a red sort of healthy face was standing there. Rather a formidable Johnnie, he looked, though quite peaceful at the moment.
Or have you dined?" I said I had. What I needed then was air, not dinner.
"Jeeves," I said, "now is the time for all good men to come to the aid of the party. A stiff b.-and-s. first of all, and then I've a bit of news for you." He came back with a tray and a long glass.
"Later on, perhaps, thank you, sir." "All right. Please yourself. But you're going to get a shock.
"Yes, sir." "And the girl who was to slide gracefully into his uncle's esteem by writing the book on birds?"
"Perfectly, sir." "Well, she's slid. She's married the uncle."
He took it without blinking. You can't rattle Jeeves. "That was always a development to be feared, sir."
"I hardly liked to take the liberty, sir." Of course, as I saw after I had had a bite to eat and was in a calmer frame of mind, what had happened wasn't my fault, if you come down to it. I couldn't be expected to foresee that the scheme, in itself a cracker-jack, would skid into the ditch as it had done; but all the same I'm bound to admit that I didn't relish the idea of meeting Corky again until time, the great healer, had been able to get in a bit of soothing work.
Corky looked over his shoulder.
"Halloa, Bertie. Don't go. We're just finishing for the day.
"Good afternoon."
Corky stood there, looking at the door, and then he turned to me and began to get it off his chest. Fortunately, he seemed to take it for granted that I knew all about what had happened, so it wasn't as awkward as it might have been. "It's my uncle's idea," he said.
"Muriel doesn't know about it yet. The portrait's to be a surprise for her on her birthday. The nurse takes the kid out ostensibly to get a breather, and they beat it down here.
'phone. "Bertie." "Halloa?"
"Are you doing anything this afternoon?" "Nothing special."
"You couldn't come down here, could you?" "What's the trouble? Anything up?"
"I've finished the portrait." "Good boy! Stout work!"
"Yes." His voice sounded rather doubtful. "The fact is, Bertie, it doesn't look quite right to me. There's something about it--My uncle's coming in half an hour to inspect it, and--
The sympathetic co-operation of Jeeves seemed to me to be indicated. "You think he'll cut up rough?" "He may." I threw my mind back to the red-faced chappie I had met at the restaurant, and tried to picture him cutting up rough.
What's Jeeves got to do with it?
Who wants Jeeves?
Jeeves is the fool who suggested the scheme that has led----"
"Listen, Corky, old top! If you think I am going to face that uncle of yours without Jeeves's support, you're mistaken. I'd sooner go into a den of wild beasts and bite a lion on the back of the neck."
"Oh, all right," said Corky.
Not cordially, but he said it; so I rang for Jeeves, and explained the situation.
"Very good, sir," said Jeeves. That's the sort of chap he is. You can't rattle him.
"As ugly as that?" I looked again, and honesty compelled me to be frank. "I don't see how it could have been, old chap."
I don't see how he could have managed it in the time. What do you think, Jeeves?" "I doubt it, sir." "It--it sorts of leers at you, doesn't it?"
"You've noticed that, too?" said Corky. "I don't see how one could help noticing." "All I tried to do was to give the little brute a cheerful expression.
"Just what I was going to suggest, old man. He looks as if he were in the middle of a colossal spree, and enjoying every minute of it. Don't you think so, Jeeves?"
"He has a decidedly inebriated air, sir."
Corky was starting to say something when the door opened, and the uncle came in. For about three seconds all was joy, jollity, and goodwill. The old boy shook hands with me, slapped Corky on the back, said that he didn't think he had ever seen such a fine day, and whacked his leg with his stick.
Jeeves had projected himself into the background, and he didn't notice him. "Well, Bruce, my boy; so the portrait is really finished, is it--really finished? Well, bring it out.
Let's----" And then he got it--suddenly, when he wasn't set for the punch; and he rocked back on his heels.
"Oosh!" he exclaimed. And for perhaps a minute there was one of the scaliest silences I've ever run up against. "Is this a practical joke?" he said at last, in a way that set about sixteen draughts cutting through the room at once.
"Corky, old top!" I whispered faintly.
Corky was standing staring at the picture. His face was set. There was a hunted look in his eye.
Thistleton, with whom I was once in service? Perhaps you have met him? He was a financier.
"I mentioned Mr. Thistleton, sir, because his was in some respects a parallel case to the present one. His depilatory failed, but he did not despair. He put it on the market again under the name of Hair-o, guaranteed to produce a full crop of hair in a few months.
Thistleton, that there is always a way. Mr. Worple himself suggested the solution of the difficulty. In the heat of the moment he compared the portrait to an extract from a coloured comic supplement.
Corky was glaring at the picture, and making a sort of dry, sucking noise with his mouth. He seemed completely overwrought. And then suddenly he began to laugh in a wild way.
Jeeves, you're a life-saver! You've hit on the greatest idea of the age! Report at the office on Monday!
Corky and I looked at the picture, then at each other in an awed way.
Jeeves was right. There could be no other title.
"Jeeves," I said. It was a few weeks later, and I had just finished looking at the comic section of the Sunday Star. "I'm an optimist.
"I took the liberty of glancing at them before bringing them to you, sir. Extremely diverting." "They have made a big hit, you know." "I anticipated it, sir."
"I have nothing to complain of in that respect, sir. Mr. Corcoran has been most generous. I am putting out the brown suit, sir."
"No, I think I'll wear the blue with the faint red stripe." "Not the blue with the faint red stripe, sir." "But I rather fancy myself in it."
Jeeves. "Eh?" "Lady Malvern, sir. She is waiting in the sitting-room."
"Pull yourself together, Jeeves, my man," I said, rather severely, for I bar practical jokes before breakfast. "You know perfectly well there's no one waiting for me in the sitting-room. How could there be when it's barely ten o'clock yet?"
"I gathered from her ladyship, sir, that she had landed from an ocean liner at an early hour this morning." This made the thing a bit more plausible. I remembered that when I had arrived in America about a year before, the proceedings had begun at some ghastly hour like six, and that I had been shot out on to a foreign shore considerably before eight.
"Is she alone?" "Her ladyship is accompanied by a Lord Pershore, sir. I fancy that his lordship would be her ladyship's son."
"Oh, well, put out rich raiment of sorts, and I'll be dressing." "Our heather-mixture lounge is in readiness, sir." "Then lead me to it."
"Indeed, sir?" "Yes. I met her at lunch one Sunday before I left London. A very vicious specimen.
"Yes, sir? Pardon me, sir, but not that tie!"
"Eh?" "Not that tie with the heather-mixture lounge, sir!" It was a shock to me.
"Unsuitable, sir." "Jeeves, this is the tie I wear!"
"Very good, sir." Dashed unpleasant. I could see that the man was wounded.
"Halloa!
Halloa!" I said. "What?" "Ah!
Motty, darling, this is Mr. Wooster." Lady Malvern was a hearty, happy, healthy, overpowering sort of dashed female, not so very tall but making up for it by measuring about six feet from the O.P. to the Prompt Side.
Motty, the son, was about twenty-three, tall and thin and meek-looking. He had the same yellow hair as his mother, but he wore it plastered down and parted in the middle. His eyes bulged, too, but they weren't bright.
Your aunt gave me your address and told me to be sure and call on you."
"No, no! Darling Motty is essentially a home bird. Aren't you, Motty darling?"
Motty, who was sucking the knob of his stick, uncorked himself. "Yes, mother," he said, and corked himself up again. "I should not like him to belong to clubs.
Motty is safe with you, Mr. Wooster. I know what the temptations of a great city are. Hitherto dear Motty has been sheltered from them.
"Jeeves! What about it?" "Sir?" "What's to be done?
It looked as if Motty, after seeing mother off at the station, had decided to call it a day. Jeeves came in with the nightly whisky-and- soda. I could tell by the chappie's manner that he was still upset.
"Lord Pershore gone to bed, Jeeves?" I asked, with reserved hauteur and what- not. "No, sir. His lordship has not yet returned."
"His lordship came in shortly after six- thirty, and, having dressed, went out again." At this moment there was a noise outside the front door, a sort of scrabbling noise, as if somebody were trying to paw his way through the woodwork. Then a sort of thud.
"Better go and see what that is, Jeeves." "Very good, sir." He went out and came back again. "If you would not mind stepping this way, sir, I think we might be able to carry him in." "Carry him in?"
There was Motty huddled up outside on the floor. He was moaning a bit. "He's had some sort of dashed fit," I said.
"Jeeves! Someone's been feeding him meat!"
"Sir?"
"He's a vegetarian, you know. He must have been digging into a steak or something. Call up a doctor!"
"I hardly think it will be necessary, sir. If you would take his lordship's legs, while I----"
"Great Scot, Jeeves! You don't think--he can't be----"
"I am inclined to think so, sir." And, by Jove, he was right! Once on the right track, you couldn't mistake it.
Motty was under the surface. It was the deuce of a shock. "You never can tell, Jeeves!" "Very seldom, sir."
"Remove the eye of authority and where are you?" "Precisely, sir." "Where is my wandering boy to-night and all that sort of thing, what?"
Tut!' and I'll apologize and remedy the defect."
"But I say, you know, what about me?" "What about you?"
"Well, I'm so to speak, as it were, kind of responsible for you. What I mean to say is, if you go doing this sort of thing I'm apt to get in the soup somewhat." "I can't help your troubles," said Motty firmly.
Tra-la! What ho!" Put like that, it did seem reasonable.
"All my bally life, dear boy," Motty went on, "I've been cooped up in the ancestral home at Much Middlefold, in Shropshire, and till you've been cooped up in Much
Middlefold you don't know what cooping is! When that happens, we talk about it for days.
The man was still thoroughly pipped about the hat and tie, and simply wouldn't rally round. One morning I wanted comforting so much that I sank the pride of the Woosters and appealed to the fellow direct. "Jeeves," I said, "this is getting a bit thick!"
"Sir?" Business and cold respectfulness. "You know what I mean. This lad seems to have chucked all the principles of a well-spent boyhood.
"Well, I shall get blamed, don't you know. You know what my Aunt Agatha is!"
"Yes, sir." "Very well, then." I waited a moment, but he wouldn't unbend.
"Jeeves," I said, "haven't you any scheme up your sleeve for coping with this blighter?"
"No, sir." And he shimmered off to his lair. Obstinate devil! So dashed absurd, don't you know.
Living with Motty had reduced me to such an extent that I was simply unable to cope with this thing. I jumped backward with a loud yell of anguish, and tumbled out into the hall just as Jeeves came out of his den to see what the matter was. "Did you call, sir?"
There's something in there that grabs you by the leg!" "That would be Rollo, sir."
"Who the deuce is Rollo?" "His lordship's bull-terrier, sir. His lordship won him in a raffle, and tied him to the leg of the table.
"Rollo is not used to you yet, sir," said Jeeves, regarding the bally quadruped in an admiring sort of way. "He is an excellent watchdog." "I don't want a watchdog to keep me out of my rooms."
I thought for a bit. "Jeeves!" "Sir?" "I'm going away--to-morrow morning by the first train.
"Do you wish me to accompany you, sir?" "No." "Very good, sir." "I don't know when I shall be back.
"Yes, sir." As a matter of fact, I was back within the week. Rocky Todd, the pal I went to stay with, is a rummy sort of a chap who lives all alone in the wilds of Long Island, and likes it; but a little of that sort of thing goes a long way with me.
Jeeves came out of his lair. I looked round cautiously for Rollo. "Where's that dog, Jeeves?
"The animal is no longer here, sir. His lordship gave him to the porter, who sold him. His lordship took a prejudice against the animal on account of being bitten by him in the calf of the leg."
"Is Lord Pershore in, Jeeves?" "No, sir."
"Do you expect him back to dinner?" "No, sir." "Where is he?" "In prison, sir." Have you ever trodden on a rake and had the handle jump up and hit you?
"Sir?" "What will Lady Malvern say when she finds out?" "I do not fancy that her ladyship will find out, sir."
"Why Boston?" "Very interesting and respectable centre, sir."
"Jeeves, I believe you've hit it." "I fancy so, sir." "Why, this is really the best thing that could have happened. If this hadn't turned up to prevent him, young Motty would have been in a sanatorium by the time Lady Malvern got back."
"Exactly, sir." The more I looked at it in that way, the sounder this prison wheeze seemed to me. There was no doubt in the world that prison was just what the doctor ordered for Motty. It was the only thing that could have pulled him up.
Shropshire, wouldn't have much to kick at in a prison. Altogether, I began to feel absolutely braced again. Life became like what the poet Johnnie says--one grand, sweet song.
I draped a few garments round me and went in.
"Won't you have an egg or something? Or a sausage or something? Or something?"
"No, thank you." She spoke as if she belonged to an anti- sausage society or a league for the suppression of eggs. There was a bit of a silence.
"Extremely, thank you." "See everything?
Niag'ra Falls, Yellowstone Park, and the jolly old Grand Canyon, and what-not?" "I saw a great deal." There was another slightly frappe silence.
Jeeves floated silently into the dining- room and began to lay the breakfast-table. "I hope Wilmot was not in your way, Mr. Wooster?" I had been wondering when she was going to mention Motty.
"You were his constant companion, then?" "Absolutely! We were always together. Saw all the sights, don't you know.
"Oh!
Wilmot is in Boston?"
"Yes. I ought to have let you know, but of course we didn't know where you were. You were dodging all over the place like a snipe--I mean, don't you know, dodging all over the place, and we couldn't get at you.
"Jeeves, Lord Pershore didn't change his mind about going to Boston, did he?" "No, sir." "I thought I was right.
"Then how do you account, Mr. Wooster, for the fact that when I went yesterday afternoon to Blackwell's Island prison, to secure material for my book, I saw poor, dear Wilmot there, dressed in a striped suit, seated beside a pile of stones with a hammer in his hands?"
I tried to think of something to say, but nothing came. A chappie has to be a lot broader about the forehead than I am to handle a jolt like this. I strained the old bean till it creaked, but between the collar and the hair parting nothing stirred.
Lady Malvern tried to freeze him with a look, but you can't do that sort of thing to Jeeves. He is look-proof. "I fancy, your ladyship, that you have misunderstood Mr. Wooster, and that he may have given you the impression that he was in New York when his lordship--was removed.
"Absolutely, by Jove! Quite pipped about it!" I said. "The idea of making a personal examination into the prison system of the country--from within--occurred to his lordship very suddenly one night.
"Absolutely!" I said. "Your breakfast is ready, sir," said
I sat down and dallied in a dazed sort of way with a poached egg.
"Jeeves," I said, "you are certainly a life-saver!" "Thank you, sir." "Nothing would have convinced my Aunt Agatha that I hadn't lured that blighter into riotous living." "I fancy you are right, sir."
"Jeeves!" "Sir?" "That pink tie!" "Yes, sir?"
"Jeeves," I said, "it isn't enough. Is there anything else you would like?"
"Yes, sir. If I may make the suggestion--fifty dollars." "Fifty dollars?"
"It will enable me to pay a debt of honour, sir. I owe it to his lordship." "You owe Lord Pershore fifty dollars?" "Yes, sir.
"I endeavour to give satisfaction, sir," said Jeeves. > CHAPTER 3 JEEVES AND THE HARD-BOlLED EGG Sometimes of a morning, as I've sat in bed sucking down the early cup of tea and watched my man Jeeves flitting about the room and putting out the raiment for the day, I've wondered what the deuce I should do if the fellow ever took it into his head to leave me.
"Oh?" I said. "Twice, sir. He appeared a trifle agitated."
"What, pipped?" "He gave that impression, sir." I sipped the whisky. I was sorry if Bicky was in trouble, but, as a matter of fact, I was rather glad to have something I could discuss freely with Jeeves just then, because things had been a bit strained between us for some time, and it had been rather difficult to hit on anything to talk about that wasn't apt to take a personal turn.
"Something must be up, Jeeves." "Yes, sir." I gave the moustache a thoughtful twirl. It seemed to hurt Jeeves a good deal, so I chucked it.
Carmantic." "Yes?"
"His Grace the Duke of Chiswick, sir." This was news to me, that Bicky's uncle was a duke. Rum, how little one knows about one's pals!
"Mr. Bickersteth is the son of his grace's late sister, sir, who married Captain Rollo
Bickersteth of the Coldstream Guards." Jeeves knows everything. "Is Mr. Bickersteth's father dead, too?" "Yes, sir." "Leave any money?"
Mr. Wooster has just returned," I heard him say.
"Halloa, Bicky!" I said.
"Jeeves told me you had been trying to get me.
Jeeves, bring another glass, and let the revels commence. What's the trouble, Bicky?"
"I'm in a hole, Bertie. I want your advice."
"Say on, old lad!" "My uncle's turning up to-morrow, Bertie."
"So Jeeves told me."
"The Duke of Chiswick, you know." "So Jeeves told me."
Bicky seemed a bit surprised.
"Jeeves seems to know everything." "Rather rummily, that's exactly what I was thinking just now myself." "Well, I wish," said Bicky gloomily, "that he knew a way to get me out of the hole I'm in."
Jeeves shimmered in with the glass, and stuck it competently on the table. "Mr. Bickersteth is in a bit of a hole, Jeeves," I said, "and wants you to rally round."
"Very good, sir." Bicky looked a bit doubtful. "Well, of course, you know, Bertie, this thing is by way of being a bit private and all that."
"I shouldn't worry about that, old top. I bet Jeeves knows all about it already.
Don't you, Jeeves?" "Yes, sir." "Eh!" said Bicky, rattled. "I am open to correction, sir, but is not your dilemma due to the fact that you are at a loss to explain to his grace why you are in New York instead of in Colorado?"
Bicky rocked like a jelly in a high wind. "How the deuce do you know anything about it?" "I chanced to meet his grace's butler before we left England.
"I get you absolutely, dear boy." "Well, when I got to New York it looked a decent sort of place to me, so I thought it would be a pretty sound notion to stop here. So I cabled to my uncle telling him that I had dropped into a good business wheeze in the city and wanted to chuck the ranch idea. He wrote back that it was all right, and here I've been ever since.
What on earth am I to do?" "Jeeves," I said, "what on earth is Mr.
Bickersteth to do?"
"You see," said Bicky, "I had a wireless from him to say that he was coming to stay with me--to save hotel bills, I suppose. I've always given him the impression that I was living in pretty good style. I can't have him to stay at my boarding- house."
"Thought of anything, Jeeves?" I said. "To what extent, sir, if the question is not a delicate one, are you prepared to assist Mr. Bickersteth?" "I'll do anything I can for you, of course,
Bicky, old man."
"Then, if I might make the suggestion, sir, you might lend Mr. Bickersteth----"
"No, by Jove!" said Bicky firmly. "I never have touched you, Bertie, and I'm not going to start now. I may be a chump, but it's my boast that I don't owe a penny to a single soul--not counting tradesmen, of course." "I was about to suggest, sir, that you might lend Mr. Bickersteth this flat.
Bicky had stopped rocking himself and was staring at Jeeves in an awed sort of way. "I would advocate the dispatching of a wireless message to his grace on board the vessel, notifying him of the change of address. Mr. Bickersteth could meet his grace at the dock and proceed directly here.
"Thank you, sir."
Bicky followed him with his eye till the door closed. "How does he do it, Bertie?" he said. "I'll tell you what I think it is.
Jeeves made a long arm and opened the front door, and the old boy crawled in, looking licked to a splinter. "How do you do, sir?"
Great pal of Bicky's, and all that sort of thing. I'm staying with him, you know. Would you like a cup of tea?
Jeeves, bring a cup of tea." Old Chiswick had sunk into an arm-chair and was looking about the room. "Does this luxurious flat belong to my nephew Francis?"
Jeeves filtered in with the tea. Old Chiswick took a stab at it to restore his tissues, and nodded. "A terrible country, Mr. Wooster!
"Oh, just business, don't you know. The same sort of thing Carnegie and Rockefeller and all these coves do, you know." I slid for the door. "Awfully sorry to leave you, but I've got to meet some of the lads elsewhere."
"Halloa, Bertie! I missed him. Has he turned up?"
Toodle-oo, Bertie, old man. See you later."
"Pip-pip, Bicky, dear boy." He trotted off, full of merriment and good cheer, and I went off to the club to sit in the window and watch the traffic coming up one way and going down the other. It was latish in the evening when I looked in at the flat to dress for dinner.
"I suppose Mr. Bickersteth is a bit braced at the way things are going--what?"
"Sir?" "I say, I take it that Mr. Bickersteth is tolerably full of beans." "Not altogether, sir." "What's his trouble now?"
"Surely the duke believes that Mr. Bickersteth is doing well in business, and all that sort of thing?" "Exactly, sir. With the result that he has decided to cancel Mr. Bickersteth's monthly allowance, on the ground that, as Mr. Bickersteth is doing so well on his own account, he no longer requires pecuniary assistance."
"Great Scot, Jeeves! This is awful."
"Somewhat disturbing, sir." "I never expected anything like this!" "I confess I scarcely anticipated the contingency myself, sir." "I suppose it bowled the poor blighter over absolutely?"
"Well, have a stab at it, Jeeves!" "I will spare no pains, sir."
I went and dressed sadly. It will show you pretty well how pipped I was when I tell you that I near as a toucher put on a white tie with a dinner- jacket. I sallied out for a bit of food more to pass the time than because I wanted it.
He had the aspect of one who had been soaked with what the newspaper chappies call "some blunt instrument." "This is a bit thick, old thing--what!" I said. He picked up his glass and drained it feverishly, overlooking the fact that it hadn't anything in it.
"Jeeves." "Sir?" There was Jeeves, standing behind me, full of zeal. In this matter of shimmering into rooms the chappie is rummy to a degree.
"Oh, there you are, Jeeves!" "Precisely, sir."
"Jeeves, Mr. Bickersteth is still up the pole. Any ideas?"
"Why, yes, sir. Since we had our recent conversation I fancy I have found what may prove a solution. I do not wish to appear to be taking a liberty, sir, but I think that we have overlooked his grace's potentialities as a source of revenue."
Bicky laughed, what I have sometimes seen described as a hollow, mocking laugh, a sort of bitter cackle from the back of the throat, rather like a gargle. "I do not allude, sir," explained Jeeves, "to the possibility of inducing his grace to part with money. I am taking the liberty of regarding his grace in the light of an at present--if I may say so--useless property, which is capable of being developed."
Bicky looked at me in a helpless kind of way. I'm bound to say I didn't get it myself. "Couldn't you make it a bit easier,
Jeeves!"
"In a nutshell, sir, what I mean is this: His grace is, in a sense, a prominent personage. The inhabitants of this country, as no doubt you are aware, sir, are peculiarly addicted to shaking hands with prominent personages.
It occurred to me that Mr. Bickersteth or yourself might know of persons who would be willing to pay a small fee--let us say two dollars or three--for the privilege of an introduction, including handshake, to his grace."
Bicky didn't seem to think much of it. "Do you mean to say that anyone would be mug enough to part with solid cash just to shake hands with my uncle?"
"I have an aunt, sir, who paid five shillings to a young fellow for bringing a moving-picture actor to tea at her house one Sunday. It gave her social standing among the neighbours."
Bicky wavered. "If you think it could be done----"
"I feel convinced of it, sir." "What do you think, Bertie?" "I'm for it, old boy, absolutely. A very brainy wheeze." "Thank you, sir.
There is no doubt that Jeeves is in a class of his own.
"Sir?" "It won't work. We can't get anybody to come."
"I fancy I can arrange that aspect of the matter, sir." "Do you mean to say you've managed to get anybody?" "Yes, sir.
Eighty-seven gentlemen from Birdsburg, sir." I sat up in bed and spilt the tea.
"Birdsburg?"
"Birdsburg, Missouri, sir." "How did you get them?" "I happened last night, sir, as you had intimated that you would be absent from home, to attend a theatrical performance, and entered into conversation between the acts with the occupant of the adjoining seat.
"Well, any way, when we get it I'll make it up to five hundred. Bicky'll never know. Do you suspect Mr. Bickersteth would suspect anything, Jeeves, if I made it up to five hundred?" "I fancy not, sir.
After breakfast run down to the bank and get me some money."
"Yes, sir." "You know, you're a bit of a marvel,
Jeeves." "Thank you, sir."
"Right-o!" "Very good, sir." When I took dear old Bicky aside in the course of the morning and told him what had happened he nearly broke down. He tottered into the sitting-room and buttonholed old Chiswick, who was reading the comic section of the morning paper with a kind of grim resolution.
"That'll be absolutely all right, uncle. There won't be a newspaper-man in the place."
"In that case I shall be glad to make the acquaintance of your friends." "You'll shake hands with them and so forth?" "I shall naturally order my behaviour according to the accepted rules of civilized intercourse."
Bicky thanked him heartily and came off to lunch with me at the club, where he babbled freely of hens, incubators, and other rotten things. After mature consideration we had decided to unleash the Birdsburg contingent on the old boy ten at a time.
Jeeves brought his theatre pal round to see us, and we arranged the whole thing with him. A very decent chappie, but rather inclined to collar the conversation and turn it in the direction of his home-town's new water- supply system. We settled that, as an hour was about all he would be likely to stand, each gang should consider itself entitled to seven minutes of the duke's society by Jeeves's stop-watch, and that when their time was up
Jeeves should slide into the room and cough meaningly. Then we parted with what I believe are called mutual expressions of goodwill, the
Birdsburg chappie extending a cordial invitation to us all to pop out some day and take a look at the new water-supply system, for which we thanked him. Next day the deputation rolled in. The first shift consisted of the cove we had met and nine others almost exactly like him in every respect.
Boost for Birdsburg!"
"Boost for Birdsburg!" said the other chappies reverently. The chappie who had been brooding suddenly gave tongue. "Say!"
Bickersteth, as I understand it. Well, if you're the Duke of Chiswick, why isn't he Lord Percy Something? I've read English novels, and I know all about it."
"This is monstrous!" "Now don't get hot under the collar. I'm only asking.
"You're quite right, Simms. I overlooked that when making the agreement. You see, gentlemen, as business men we've a right to reasonable guarantees of good faith.
"Allow me to assure you, sir," he said, in a rummy kind of voice, "that I am the Duke of Chiswick." "Then that's all right," said the chappie heartily. "That was all we wanted to know. Let the thing go on."
"I am sorry to say," said old Chiswick, "that it cannot go on. I am feeling a little tired. I fear I must ask to be excused." "But there are seventy-seven of the boys waiting round the corner at this moment, Duke, to be introduced to you."
"I fear I must disappoint them." "But in that case the deal would have to be off." "That is a matter for you and my nephew to discuss."
"Well, then, I guess we'll be going." They went out, and there was a pretty solid silence. Then old Chiswick turned to Bicky: "Well?"
Bicky didn't seem to have anything to say. "Was it true what that man said?" "Yes, uncle."
Bicky's Adam's-apple jumped about a bit; then he started: "You see, you had cut off my allowance, uncle, and I wanted a bit of money to start a chicken farm. I mean to say it's an absolute cert if you once get a bit of capital.
"What is all this nonsense about hens? You led me to suppose you were a substantial business man."
"Old Bicky rather exaggerated, sir," I said, helping the chappie out. "The fact is, the poor old lad is absolutely dependent on that remittance of yours, and when you cut it off, don't you know, he was pretty solidly in the soup, and had to think of some way of closing in on a bit of the ready pretty quick. That's why we thought of this handshaking scheme."
"After what has happened? After this--this deceit and foolery? Not a penny!"
"But----" "Not a penny!" There was a respectful cough in the background. "If I might make a suggestion, sir?"
Jeeves was standing on the horizon, looking devilish brainy. "Go ahead, Jeeves!" I said. "I would merely suggest, sir, that if Mr. Bickersteth is in need of a little ready money, and is at a loss to obtain it elsewhere, he might secure the sum he requires by describing the occurrences of this afternoon for the Sunday issue of one of the more spirited and enterprising newspapers." "By Jove!"
"Great heavens!" said old Chiswick. "Very good, sir," said Jeeves. Bicky turned to old Chiswick with a gleaming eye.
"Jeeves is right. I'll do it! The Chronicle would jump at it.
"Wait! Er--wait, my boy! You are so impetuous!
"I won't go to that bally ranch." "No, no! No, no, my boy!
"I shouldn't mind that." "I should not be able to offer you a salary, but, as you know, in English political life the unpaid secretary is a recognized figure----" "The only figure I'll recognize," said Bicky firmly, "is five hundred quid a year, paid quarterly." "My dear boy!"
"Absolutely!" "But your recompense, my dear Francis, would consist in the unrivalled opportunities you would have, as my secretary, to gain experience, to accustom yourself to the intricacies of political life, to--in fact, you would be in an exceedingly advantageous position."
Chappies keep them on ice for years and years, and don't sell them till they fetch about a dollar a whirl. You don't think I'm going to chuck a future like this for anything under five hundred o' goblins a year--what?"
A look of anguish passed over old Chiswick's face, then he seemed to be resigned to it. "Very well, my boy," he said. "What-o!" said Bicky.
Bicky had taken the old boy off to dinner to celebrate, and we were alone.
"Jeeves, this has been one of your best efforts." "Thank you, sir." "It beats me how you do it." "Yes, sir."
"I fancy Mr. Bickersteth intends--I judge from his remarks--to signify his appreciation of anything I have been fortunate enough to do to assist him, at some later date when he is in a more favourable position to do so."
"It isn't enough, Jeeves!" "Sir?"
It was a wrench, but I felt it was the only possible thing to be done. "Bring my shaving things." A gleam of hope shone in the chappie's eye, mixed with doubt. "You mean, sir?" "And shave off my moustache."
People have called me a silly ass, but I was never in the same class with Bobbie. When it came to being a silly ass, he was a plus-four man, while my handicap was about six. Why, if I wanted him to dine with me, I used to post him a letter at the beginning of the week, and then the day before send him a telegram and a phone-call on the day itself, and--half an hour before the time we'd fixed--a messenger in a taxi, whose business it was to see that he got in and that the chauffeur had the address all correct.
Bobbie broke the news to me at the club one evening, and next day he introduced me to her. I admired her. I've never worked myself--my name's Pepper, by the way.
Almost forgot to mention it. Reggie Pepper. My uncle Edward was Pepper, Wells, and Co., the Colliery people.
"She--mentioned it," he said thoughtfully. I didn't ask for details. Women with hair and chins like Mary's may be angels most of the time, but, when they take off their wings for a bit, they aren't half-hearted about it.
"my stock's pretty low at home." There didn't seem much to be done. I just lit a cigarette and sat there. He didn't want to talk.
Bobbie's married life. Of course, one's always mildly interested in one's friends' marriages, hoping they'll turn out well and all that; but this was different. The average man isn't like Bobbie, and the average girl isn't like Mary.
Bobbie, she's proud of him, and doesn't want her handiwork disturbed. She gives him a sort of natural armour to protect him against outside interference. And that armour is shortness of memory.
I'm a chump. Well, if I had remembered half the things people have tried to teach me during my life, my size in hats would be about number nine.
Elephants, I read somewhere, are champions at the memory business, but they were fools to Bobbie during that week. But, bless you, the shock wasn't nearly big enough. It had dinted the armour, but it hadn't made a hole in it.
"I suppose you're right," said Bobbie. "But it beats me why she thinks such a lot of these rotten little dates. What's it matter if I forgot what day we were married on or what day she was born on or what day the cat had the measles?
"That's not enough for a woman," I said. "They want to be shown. Bear that in mind, and you're all right.
Bobbie didn't get into the soup all at once. Weeks went by, and months, and still nothing happened. Now and then he'd come into the club with a kind of cloud on his shining morning face, and I'd know that there had been doings in the home; but it wasn't till well on in the spring that he got the thunderbolt just where he had been asking for it--in the thorax.
I was smoking a quiet cigarette one morning in the window looking out over Piccadilly, and watching the buses and motors going up one way and down the other--most interesting it is; I often do it--when in rushed Bobbie, with his eyes bulging and his face the colour of an oyster, waving a piece of paper in his hand.
"Reggie," he said.
"Reggie, old top, she's gone!" "Gone!" I said. "Who?" "Mary, of course!
"Where?" I said. Anyhow, dear old Bobbie nearly foamed at the mouth.
"But she says on her birthday." "Well, when is her birthday?"
"Can't you understand?" said Bobbie. "I've forgotten." "Forgotten!" I said.
"I know it came somewhere between the first of January and the thirty-first of December. That's how near I get to it."
"Think." "Think? What's the use of saying 'Think'?
"And you can't remember?" "No." I rang the bell and ordered restoratives. "Well, Bobbie," I said, "it's a pretty hard case to spring on an untrained amateur like me.
"Well, fairly cold, perhaps. I can't remember." I ordered two more of the same.
Bobbie seemed to be thinking. "I've got it," he said suddenly. "Look here.
Bobbie's idea was to buy the whole twelve, and go through them till we found out which month hit off Mary's character. That would give us the month, and narrow it down a whole lot. A pretty hot idea for a non-thinker like dear old Bobbie.
Well, Mary had certainly kept her secret, and she had travelled quite extensively enough for Bobbie's needs. Then, October people were "born with original ideas" and "loved moving." You couldn't have summed up Mary's little jaunt more neatly.
Bobbie was all for May, because the book said that women born in that month were "inclined to be capricious, which is always a barrier to a happy married life"; but I plumped for February, because February women "are unusually determined to have their own way, are very earnest, and expect a full return in their companion or mates." Which he owned was about as like Mary as anything could be. In the end he tore the books up, stamped on them, burnt them, and went home.
"Reggie," he said, "I'm on the trail. This time I'm convinced that I shall pull it off. I've remembered something of vital importance."
"Yes?" I said. "I remember distinctly," he said, "that on Mary's last birthday we went together to the Coliseum. How does that hit you?" "It's a fine bit of memorizing," I said;
"but how does it help?" "Why, they change the programme every week there." "Ah!" I said. "Now you are talking." "And the week we went one of the turns was
Reggie, I'm going round to the Coliseum this minute, and I'm going to dig the date of those Terpsichorean Cats out of them, if I have to use a crowbar." So that got him within six days; for the management treated us like brothers; brought out the archives, and ran agile fingers over the pages till they treed the cats in the middle of May. "I told you it was May," said Bobbie.
He didn't apologize. "Reggie," he said, "I've got it now for certain. It's just come to me.
"Yes?" I said. "Well, don't you see that that brings it down to two days? It must have been either Wednesday the seventh or Saturday the tenth."
"Yes," I said, "if they didn't have daily matinees at the Coliseum." I heard him give a sort of howl.
"Bobbie," I said. My feet were freezing, but I was fond of him. "Well?" "I've remembered something too.
"But I'm always writing cheques." But this was for a tenner, and made out to the hotel.
"Reggie," he said, "you're a genius. I've always said so. I believe you've got it.
"Halloa!" he said.
"I'm here," I said. "It was the eighth. Reggie, old man, I----"
"Topping," I said. "Good night." It was working along into the small hours now, but I thought I might as well make a night of it and finish the thing up, so I rang up an hotel near the Strand.
"Put me through to Mrs. Cardew," I said. "It's late," said the man at the other end. "And getting later every minute," I said.
"Oh! is that Mr. Pepper?"
"Yes. He's remembered it, Mrs. Cardew." She gave a sort of scream.
The things they must hear, don't you know. Bobbie's howl and gulp and Mrs. Bobbie's scream and all about my feet and all that. Most interesting it must be.
"Yes?" "Was he--has he been--was he very worried?" I chuckled. This was where I was billed to be the life and soul of the party.
"But----"
"And you call yourself his friend! His friend!" (Metallic laugh, most unpleasant.) "It shows how one can be deceived.
"But, I say, when I suggested the thing, you thought it perfectly----"
"I thought it hateful, abominable." "But you said it was absolutely top----"
"I said nothing of the kind. And if I did, I didn't mean it. I don't wish to be unjust, Mr. Pepper, but I must say that to me there seems to be something positively fiendish in a man who can go out of his way to separate a husband from his wife, simply in order to amuse himself by gloating over his agony----"
"But----!" "When one single word would have----" "But you made me promise not to----" I bleated. "And if I did, do you suppose I didn't expect you to have the sense to break your promise?"
Now I'm going to give you a story. It's an Indian story about an Indian woman and her journey. Let me begin with my parents.
"I'm going to spread all my four daughters in four corners of the world." I don't know if he really meant [that], but it happened. I'm the only one who's left in India.
One thousand prisoners who sat in meditation. This was one of the most courageous steps I took as a prison governor.
One last thing and we've been avoiding bringing this up until now, but it's something you as an entrepreneur should know, it's a secret. And it's a secret that we didn't even understand for a long time and that secret is there are four types of startups and not knowing which type you are can really sink your company. So we call this market type.
Well, I'm involved in other things, besides physics. In fact, mostly now in other things. One thing is distant relationships among human languages.
(Applause)
The Awareness Of Knowledge Against The Suffering Of The Ego When we are suffering because of someone, Then, how do we solve that?
At that point, the ahamkar feels so much aaghat. [We feel] "I really don't know, but why are you hurting me?" that arises within.
And "who" is the one having this internal suffering and "Who" is the knower of this that is my Real Self.
That Absolute Knowledge (keval gnan) form is verily my own Real form. I am pure Soul, The Form of Absolute Knowledge (keval gnan).
There is also that in Aptavani 12, there is a chapter named "depression". In there, there is how to bring about solutions to ahamkar. Because ahamkar is our past life's mistakes that have been made.
You should tell ahamkar "say it". "You" are separate. The suffering ahamkar, is suffering because of the intellect.
Then we should sit on this side and say "I am Pure Soul",
"I am full of infinite bliss",
"I am full of infinite energy", "I am absolutely separate from all joint actions of mind, speech, and body". We keep saying all these.
Dada says "that is good. It is a profit." The man says, "Dada, you're saying its good, but I can't bear it".
But use solutions from these books: Flawless vision (Nijdosh Darshan), or in Aptavani 12. then Aptavani 9 has a big chapter on pride (maan) and insult (upmaan). Then there are lots of proofs to set flawless vision.
If someone asks, "why have you become so weak?" And you'll answer, "He told me off in front of everyone" And that guy will say "He said that you".
There is a chapter "Tapa" in Aptavani 12.
There is a chapter on the "seat of I-ness" and "To become one with the situation (tanmayakar)". They all talk about these things. The state of jagruti is such that you see the fault as separate, see the other person as faultless and to remain in the seat of pure Soul.
Through the nimit of "sticky files", if there was any type of internal suffering of the ahamkar, through dwesh (abhorrence) , through abhaav (aversion) through tiraskar (contempt); or through any type of because of the nimit of the other person if my own ahamkar was hurt. in those events, setting the jagruti of the five Agnas keeping the awareness of separation, seeing the other person as 100% nirdosh (faultless), the ahamkar (ego), the burning ahamkar, the internally suffering ahamkar, until it [the ego] becomes ashes keeping it separate, give me the strength to do this type of sayamik. In seeing the other person as nirdosh, using the keys of Dada's gnan, the intellect's interferences to bring samadhan (closure and inner satisfaction) in every way.
Give me the strength to set this jagruti. [I surrender ] my mind-speech-body All the illusory attachments associated with my name
In this video, we will show you how to use the automatic tool presetter option for Haas CNC turning centers
The automatic tool presetter offers three modes of operation: Manual mode is used for initial setup of tool offsets Automatic mode is used to update offset values after a tool's inserts have been changed
Check that "Manual" is selected in the "OP Mode" box The turret is at tool position number 12 and therefore the "Tool Number" box reads "12" This box will always display the current turret tool position
Here is a quick demonstration of the break detect routine running within our existing part program The part program is just ending a drilling operation Before continuing to a tight tolerance boring operation the machine will now automatically check that the next tool's insert is within size tolerance
That's all I'd like to say about shortest paths and weighted graphs in this unit. There's some I think interesting questions on the homework for you to get to know this concept better and to work with it and apply it to some interesting social networks. I'm going to take this last topic for this unit to be estimating the clustering coefficient.
The expected value of the connectivity of w and x for uniformly and randomly selected w and x from the set of neighbors. So write that code and we'll test it for you.
Welcome to the presentation on dividing fractions. Let's get started. So before I give you the intuition-- actually, I might do that in a different module-- I'm just going to show you the mechanics of how you divide a fraction.
But isn't this also the same thing as 2 times the inverse of 2, which is 1?
I'll show it to you. Actually, let me give you a couple more examples to show that dividing fractions really isn't a new concept, this whole notion of multiplying by the inverse. If I were to tell you what is 12 divided by 4?
So let's do some fraction division problems. What is 2/3 divided by 5/6?
Well, we know that this is the same thing as 2/3 times 6/5, and that's equal to 12/15. We can divide the numerator and denominator by 3, that's 4/5. What is 7/8 divided by 1/4?
I think you might be getting it now. Let's see, let's do a couple more. And, of course, you can always pause, and look at this whole presentation again, so you can get confused all over again.
Ah-ha! So what happens when you take a fraction and you divide it by a whole number or an integer? Well, we know any whole number can be written as a fraction.
And what is the maximum possible clustering coefficient for a node in B? Only consider nodes with degree greater than 2.
What I wanna do this video is prove that the opposite angles of a parallelogram are congruent So, for example, we wanna prove that CAB is congruent to BDC So, that angle is equal to that angle and that ABD, which is this angle is congruent to DCA which is that angle over here
The right way to think about this is of all the terms in the sum here, you need to take the one with the fastest growth rate. Log n is piddly as n gets big compared to n, and n is actually pretty piddly as n gets big compared to n².
N² is really the only thing that matters here.
This constant in front of the n² is not going to matter in Big Theta world, because we can go above it or below it. Any coefficient in here gives you the same answer. These terms drop out.
What was the translation applied to move the blue solid shape to the orange dashed shape?
So if you were to start with this blue solid shape, and you wanted to shift it to where the orange dotted shape is, how would you do that? And the way that I like to think about it is to just pick a point, and see what had to happen to that point.
So this point at the top of this - I guess - this quadrilateral-looking thing, it moved down here.
So it moved one to the left. And it moved one down.
So we can denote that with a transformation.
Moving one to the left is negative one (-1) in the horizontal direction. If we were moving to the right, it would have been a positive one (+1).
And we moved one down, in the vertical direction.
And that is another negative one (-1).
So let's follow our Jersey Square team and see what they did with customer segments. Now, what happened is, they got out of the building and this time, after they spoke to a series of customers, they spoke to over 60. And what they found out was what they originally thought was a single customer segment actually turned out to be there were two separate segments.
We put all these together, and we have a great series of hypotheses. What's interesting is the word hypotheses. I call that a $50 word.
I had dinner between the last video and this one. So I might have forgotten what I just did. I think I was about to-- if what I see on my board makes sense-- I was about to use the Taylor series, or in this specific example the Maclaurin series approximation, to figure out a polynomial version, a sum of polynomial terms to approximate e to the x.
And remember let me write here what the definition of the Maclaurin series was. That we said that f of x is equal to the sum from n equals 0 to infinite of the nth derivative of f evaluated at 0-- I don't know if I remembered to put it evaluated at 0 last time I wrote this down-- times x to the n over n factorial. And hopefully that makes sense to you.
Let me write the approximate. I'll call that p of x.
Well in this particular case, what's the derivative of any derivative evaluated at f of 0? Well that term is 1. We wrote that down right here. f of 0 is 1.
But it actually turns out that we take the infinite sum that the Maclaurin series not only approximates e to the x at x equals 0. When you take the infinite series, it actually equals e to the x. So when you take a Maclaurin series at 0, and the resulting function, the resulting polynomial actually converges-- and that's something we'll learn a little bit more rigorously hopefully later when we start doing analysis-- but it can actually converge to the function at all points.
Maclaurin series, that actually has a certain beauty to it. This number is kind of ugly when you write it out, 2.7 whatever, whatever. But when you write it to an exponent power as an infinite sum, it kind of has a nice rhythm to it.

All right, before we actually write a code that carries out this procedure, let's do an example. Here's a lovely heap. In fact, well, I just covered this up.
One of the interesting thing about a startup is how is your company going to be organized? What we now know is the most efficient way to think about all the pieces just all the parts is by a business model. And so the next question is okay, Steve just told me think about a business model but what is a business model?
The next piece about customer development to understand is what is it you're actually doing outside the building? And what I think about is you're really testing on the highest possible level your understanding of the customer's problem or need. You implicitly had a hypothesis.
"The teen girls are actually enthusiastic, in fact, trying to figure out how to buy our product right now."
I have a list of numbers here And my goal over the course of this video Is to actually order these numbers.
Now the last interesting thing that's a holdover from thinking about startups as smaller versions of large companies is kind of the hardest to get your height around. And that's large companies, they got VP of sales, what we need of VP of sales on day 1. Large companies, they have had some marketing.
"Listen, we're not going to have sales marketing and bus dev on day 1. We're not going to hire a VP of sales on day 1. We're actually going to have the founder get out of the building."
My name is Joshua Walters. I'm a performer. (Beatboxing) (Laughter) (Applause)
I reframe that as a positive because the crazier I get onstage, the more entertaining I become. When I was 16 in San Francisco, I had my breakthrough manic episode in which I thought I was Jesus Christ.

At least that's what it says on my pen." (Laughter) Some of you are in the field, I can see.
How much depends on where you fall in the spectrum. How much depends on how lucky you are. Thank you.
In the last video we saw that if we had a market with perfect competition and if the current short-term equillibrium price is above the price necessary or is above the price at which the firms would be generating economic profit then more and more firms would start entering because if the economic profit is positive then that means it is a better place to use your resources than whatever your opportunity cost is You're making profit above and beyond your opportunity cost so more and more enter it so after a little bit after one company enters it or maybe the same firm starts adding more seat-miles or adding more planes we have another short-term supply curve that looks like that and then a new equilibrium price that's a little bit lower and a new equilibrium quantity that's a little bit higher and that keeps happening still your equilibrium price was higher than your price necessary for a normal profit or a zero economic profit and so more people enter still and so we have another short term supply curve and we move further to the bottom right of this demand curve and then it keeps happening until we have a supply curve where the equilibrium price where this new short term equilibrium price is the same as the price at which everyone is making a normal profit or the price needed for zero economic profit. at that point people are neutral whether they drop out or enter into the market and so the quantity remains stable and so that's why we view each of these curves over here as our short run supply curves but this line right over here we do in yellow this line over here we've talked about this in previous videos that's why this line over here we call the long run supply curve because depending on whether the equilibrium price is above or below this at some point the supply will enter or exit the system so that we eventually get back to some point along this long run supply curve right over here Now this was assuming perfect competition many players identical products identical air travel no barriers to entry
Welcome back. In this presentation, I actually want to show you how we can use the antiderivative to figure out the area under a curve. Actually I'm going to focus more a little bit more on the intuition.
So this is just a formula that tells us the position, kind of how far has something gone, after x many, let's say, seconds, right? So after like, 4 seconds, we would have gone, let's say the distance is in feet, this is in seconds. After 4 seconds, we would have gone 256 feet.
So actually, if you look at it, I mean you could just eyeball it. The object, every second you go, it's going a little bit further, right? So it's actually accelerating.
Maybe I should switch back to, let me write that, v equals velocity. I don't know why I switched colors, but I'll stick with the yellow. So let's graph this function.
It's pretty straight.
I'm doing pretty good.
So this, I'll draw it in red, this is this going to be a line, right?
32t it's a line with slope 32. So it's actually a pretty steep line. I won't draw it that steep because I'm going to use this for an illustration.
This is velocity. This is that graph, and this is distance, right? So in case you hadn't learned already, and maybe I'll do a whole presentation on kind of using calculus for physics, and using derivatives for physics.
Right, this is the velocity, so say we had over this very small change in time, we have this roughly constant velocity that's on this graph. Actually, let me take do it here. We have this roughly constant velocity.

If we have 2 groups and in each group I have 4, (so that's one group of 4) (and then here is my second group of 4) we already know that we could write this as 2 times 4 which is the same thing as 4 plus 4. Notice, I have 2 fours here. I have 4 plus another 4, which is going to be equal to...
1, 2, 3, 4 twos. 2 plus 2 plus 2 plus 2 is equal to 8. These are both equivalent.
1, 2. Here we have 4 twos and we're adding them together:
1, 2, 3, 4. We take our 4 twos and we add them together. How else we could we represent 8?
8, 16, 24, 32.
Or you could've said: 8 plus 8 is 16, plus 8 is 24, plus 8 is 32.
So for the past year and a half, my team at Push Pop Press and Charlie Melcher and Melcher Media have been working on creating the first feature-length interactive book. It's called "Our Choice" and the author is Al Gore. It's the sequel to "An Inconvenient Truth," and it explores all the solutions that will solve the climate crisis.
This is one of my favorites. So this shows ...
(Laughter) (Applause) When the wind is blowing, any excess energy coming from the windmill is diverted into the battery. And as the wind starts dying down, any excess energy will be diverted back into the house -- the lights never go out.
So that's Push Pop Press' first title, Al Gore's "Our Choice." Thank you.
(MM: Yes.) All right.
The next is channels. How does your product over here get to your customers over here? We use distribution channels to do that.
Asking for Forgiveness First of all, the meaning of pratikraman is to turn around from our sins, our faults. Wash out [our] faults.
For all of these [instances], wherever we do atikraman, then immediately [do pratikraman] shoot-at-site. The moment we make a mistake, get rid of it instantly by doing pratikraman.
When the [mistake] remains pending then it will pile up and become a heap. Then we will not see a single mistake and will not recognize the mistakes So then, even if we do pratikraman, there won't be an end to it.
Where does all of this come in play? We have attained such immense bliss of the Self, So much peace, state of bliss [nidakudta] is coming into experience.
So many [atikramans] are happening
Ordinarily, we are seated here... it is always crowded, so during satsang we all sit closely packed together Just the way everyone is seated right now. In this, if someone has a yawn and elbows the person sitting beside him,
So then, he should do pratikraman right away for it. That, "oh I spoilt my inner intent towards that person through my mind." Then, the photographs that we take are the mistakes of the chit
This is called a "spoiled chit". These are atikramans done through the chit. "What are you laughing for?" This is the monkey business all of you have done.
Then through the intellect (buddhi)! Atikraman through the intellect We have "hit" [taken advantage of] someone through our intellect.
Many women trick their husbands through their intellect. They deceive them through their intellect. Such forms of deceit!
This is the ego. [These] mistakes of the ego.
If we harass someone, harass someone through our ego, hurt someone, Ego implies a person with a superiority complex keeps crushing a person with an inferiority complex. In reality, one has to give him love and nurture him through love.
"Why are they doing this to me?" all these atikramans [you have done] will not leave you all these [atikrakramans] will have to be repaid - compulsorily
Do you understand? these atikramans will not leave you, you will have to repay each of them So if you want to save yourself from all these repayments then, everyone wholeheartedly wherever, whatever [mistakes] have occurred do pratikraman for all of these and become free. Otherwise, all of this will come back on us.
"Remorse is an unending stream, flowing down from the heavens, Sinners bathe in it, and become fortunate." No matter how many atikramans you may have committed, but pratikraman frees you from all the sins
Youngsters come and tell me that, "Niruma, while we do pratikraman for sexuality, at that same time, atikraman towards it starts to happen." The atikraman starts again for the girl... ... whom we had already spoilt our intentions for.
I would like to talk today about what I think is one of the greatest adventures human beings have embarked upon, which is the quest to understand the universe and our place in it. My own interest in this subject, and my passion for it, began rather accidentally. I had bought a copy of this book,
"The Universe and Dr. Einstein" -- a used paperback from a secondhand bookstore in Seattle. A few years after that, in Bangalore, I was finding it hard to fall asleep one night, and I picked up this book, thinking it would put me to sleep in 10 minutes.
Anil Ananthaswamy: And I'll finally like to leave you with two images. This is an observatory in the Himalayas, in Ladakh in India.
Here are four examples of distribution channels--system integrator, dealer, web, direct sales. I want you to start thinking about which channel can handle the most complexity and which channel can handle the least. Enter the numbers 1 through 4.
Here's an example of a graph--imagine this is a social network graph, and we're going to look at the degree centrality of the nodes in the graph. Let's take a look at node 5. Node 5 has a degree centrality of 2 which really just means it has a degree of 2--there's 2 edges coming out of it.
So let's add it.
So you want to start off in the smallest place. So you start off here. This is the tenths, hundredths, thousandths place.
You can add as many zeroes to the right of this decimal, to the right of the 7, as you want, since we're sitting on the right side of the decimal, without changing its value. You can also do it here.
This 5.67, you can write it as 5.670. When you write it like this, and you have 6 plus 0 plus 0 is 6. And you keep going.
5 plus 0 plus 7 is 12. You write the 2 in the hundredths place, and carry the 1. 1 plus 0 plus 7 is 8, plus 6 is 14.
Write the 4, regroup the 1 into the ones place. 1 plus 7 is 8.
8 plus 5 is 13.
13 plus 5 is 18. This is 18.
Carry or regroup the 1. 1 plus 0 is just 1. And then finally.
Good morning Mr Fredrickson.
You're ready to go?
I'll meet you at the van.
Just a minute.
I wanna say one last goodbye to the old place.
Sure.
Take all the time you need, sir.

Morning Action Breaking News
I'm standing adjacent to the location where yesterday onlookers witnessed a lift off by what some are calling a flying house
Tell us what you saw
Construction workers in the area say the flying house belongs to this man... recently convicted public menace Carl Fredrickson
City officials say the search will continue but after yesterday's storm there may be no clues as to where Carl Fredrickson and his house have gone.
It appears as if elderly public menace Carl Fredrickson has indeed escaped
Yeaaaa ataboy Carl!
One Week Later
Okay...
Here we go
Are.. you ready?
Yeah
Good morning Mrs. Peterson
You ready to go.. go..
Oh no

(good) afternoon boys
Mr. Fredrickson!
That was so cool
let's do that again Mr. Fredrickson but next time I want to steer
That was the craziest thing I've ever seen
Hi there!
How many cups are in 3 and 1/2 gallons? So before even addressing this question, let's just think about how large a cup is. Actually, I'll give you a little bit of overview of how many cups there are in a pint, how many pints in a quart, and how many quarts in a gallon.
There are 16 cups per gallon. When you multiply these two quantities, the gallons will cancel out, and you'll just be left with cups, and that's what we wanted. So it's going to be 7/2 times 16.
You could divide 16 by 2 to get 8.
2 divided by 2 is 1. So it just becomes 7 times 8 divided by 1, or just 7 times 8, which is 56. So this is equal to 56 cups.
Prior to the dawn of Western civilization and written language science and spirituality were not two separate things. In the teachings of the great ancient traditions the outer search for knowledge and certainty was balanced by an inner feeling of impermanence and intuitive understanding of the spiral of change. As scientific thinking became more dominant and information multiplied, fragmentation began to occur within our knowledge systems.
"The eye with which I see God and the eye with which God sees me is one and the same." In the King James bible Jesus said, "the light of the body is the eye, if therefore thine eye be single, thy whole body shall be full of light." The Buddha said, "the body is an eye."
Resegmented market--well, you have a hypothesis about who the customers are-- that is you think you understand what your fit is, either in the low cost or there are specific in each needs and so you might have a better fit for them. And competitors, there's many if you're wrong but very few if you're right, and your risk is that you get the market and product redefinition just wrong. You didn't do enough customer discovery and you say--
"No, no, no. This is how we're going to enter this existing market. We're going to go after these set of usuals specifically," and oops, you are wrong.
Let's just take a look again if there's activities. If you remember what we're trying to do is get, keep and grow customers, and so these things on the left with all these arrows going into the funnel, those represent all the demand creation activities you were doing either paid or free. And in the physical channel that we're getting you into the funnel on the top.
6 is definitely 5 or larger, so we want to round up.
So this 9.564 becomes 9.6, or we can call this nine and six tenths. And then we're done!
Now the last thing I think I really want to mention and it really does belong in this lecture is the affect of market type on revenue. This is really interesting, because you might have heard about startups about something called the hockey stick, and the hockey stick is actually this kind of curve. Now, it turns out that what the hockey stick really represents are startups in a new market.

>> First, probably the most important thing, is that we actually quarry whether or not all the images have been loaded. If we don't do this little step, where we query this.fullyLoaded, then what's going to happen is you can go through your draw function trying to draw image data that hasn't actually been loaded into memory. Of course, you'll just see nothing on the screen but it's generally a good practice to let the entire thing load before you try to start working on it.
Here's another problem that Kortaggio sent me and, like the other two, this is quite interesting. Although, I think you'll start to see a pattern forming in how these are solved.
So in 12 minutes this is how far-- oh sorry --this is how far Chelsea travels, that's a c. And this is how far Alice travels, and she is going to travel 400 meters more. OK, that's what those two equations tell us.
And then in t minutes-- and that's what we're going to have to solve the problem for --b is going to have to travel 300 meters more than Chelsea right there. We just solve for t, so let's just solve for t. So what do you get?
Let's see, if we divide both sides by 6-- well, let's subtract 100 from both sides. So you have Bill's velocity times 6-- that's just that
--is equal to 6 times Alice's velocity minus 100. All I did is I subtracted 100 from both sides of this equation and I swapped the sides. Divide both sides by 6.
Va, the velocity of Alice, minus 100/6 minus vc. So minus this right here.
Minus va minus 400/12. This should simplify to t-- I'll just arbitrarily switch colors. t is equal to 300/va minus-- what's 100/6?
100/6 is the same thing as 50/3. Distribute the minus sign.
Minus va-- we can already see these are going to cancel out
--minus times a minus plus 400/12 is the same thing is 200/6 or 100/3. Right? Plus 100/3.
We're on problem 21. Stan's solution to an equation is shown below. All right, and I haven't looked at it yet, but let's just see what they ask us.
8 times n plus 20 is 8n plus 160. So that's wrong. So he made a mistake in step 1.
Well, I mean, if I have a negative number, the opposite of a negative is positive. So it's not going to be less. But if I positive number, then the opposite of it is negative, which is less than it.
That's what the y-intercept is.
Next problem.
OK, they've drawn us a graph.
They say-- let me copy and paste this one.
Copied it.
OK, which inequality is shown on the graph below?
So first of all, let's figure out the equation of this line right now.
So what's its y-intercept, first of all?
So when x is equal to 0, y is equal to minus 1.
If we put it in slope y intercept form, the equation of really, any line is y is equal to mx plus b.
Where m is the slope and b is the y-intercept.
Here, when x is 0, y is negative 1.
So the y-intercept is minus 1.
So b is minus 1.
So we know that y is equal to mx minus 1.
And now we just have to figure out the slope.
And the slope is just change in y for a given change in x.
So if we say change in y for a given change in x is equal to-- let's see.
When I increase x by 2, I increase y by 1.
So change in y is 1 when the change in x is 2.
And you could say when you increase x by 4-- I'm going four spots-- I increase y by 2.
So you could have done that.
You could have said change in y over change in x is 2/4, which is also equal to 1/2.
But either way, we now know the slope.
The slope is change in y over change in x.
So the equation of the line is y is equal to 1/2 x minus 1.
That's the equation of this line.
Now they want to know what the equation of the inequality is.
So first of all, they're including-- they have this grey area and they put this line in bold.
So that means that we're including the line.
If they had drawn a dotted line here that means we're not including the line.
But since they're including the line, it's going to be either greater than or less than or equal to.
That equal to is because we're including the line.
But just think about it.
So our choices are y is greater than or equal to 1/2 x minus 1 or y is less than or equal to 1/2 x minus 1.
Now think about for any given x.
Let's say when x is equal to 2.
When x is equal to 2, if you put it into this equation you get y is equal to 0 and that's this point on the line.
Now is the grey area all y values greater than 0 or all y values less than 0?
Well clearly, it's all y values greater than 0.
It's all the y values above the y value dictated by this equation.
The equation of this inequality or this area is y is greater than 1/2 x minus 1. And just a very easy way to eyeball it is OK, they're including the line, so I'm going to have this equal then-- it's going to either be greater than or equal to or less than or equal to, and since it's the area above the
Next problem, problem 25. This is another one where I think it makes sense to copy and paste it. It's a big one.
Which best represents the graph of y id equal to 2x minus 2. So the slope is 2. Its positive 2 and its y-intercept is minus 2.
If I increase x value by 2, what's happening to my y value? Is it increasing by 2 or is it decreasing by 2? Well it's decreasing.
OK, so they're giving us another one of these where they shaded a graph. These are good.
So they ask us, which inequality does the shaded region of the graph represent? So once again, it'll be good just to figure out what the equation of this line is. We could immediately say, OK, the y-intercept is 2.
The change in y is minus 3. It goes down by 3. So the slope is equal to minus 3.
So the equation of this line is y is equal to minus 3x plus 2. mx plus b. And if I look at the choices, already it looks a little bit different than that, but we'll get to that. But let's see what the inequality is.
So the shaded region is y is less than or equal to minus 3x plus 2.
And you can eyeball this. You can kind of say, oh, this is below the graph, so it's less than or equal.

I'm working a lot with motion and animation, and also I'm an old DJ and a musician. So, music videos are something that I always found interesting, but they always seem to be so reactive. So I was thinking, can you remove us as creators and try to make the music be the voice and have the animation following it?

Now, I want to start with a question: When was the last time you were called "childish"?
For kids like me, being called childish can be a frequent occurrence. Every time we make irrational demands, exhibit irresponsible behavior, or display any other signs of being normal American citizens, we are called childish. Which really bothers me.
The traits the word "childish" addresses are seen so often in adults, that we should abolish this age-discriminatory word, when it comes to criticizing behavior associated with irresponsibility and irrational thinking. (Applause) Thank you.
Now, when you think of glass, you might think of colorful Chihuly designs, or maybe Italian vases, but kids challenge glass artists to go beyond that, into the realm of brokenhearted snakes and bacon boys, who you can see has meat vision. (Laughter) Now, our inherent wisdom doesn't have to be insider's knowledge.
I'm going to withhold her ability to get more money from me, until she pays it back. (Laughter) True story, by the way.
Now, adults seem to have a prevalently restrictive attitude towards kids, from every "Don't do that, don't do this" in the school handbook, to restrictions on school Internet use. As history points out, regimes become oppressive when they're fearful about keeping control. And although adults may not be quite at the level of totalitarian regimes, kids have no or very little say in making the rules, when really, the attitude should be reciprocal, meaning that the adult population should learn and take into account the wishes of the younger population.
"The Wheels on the Bus Go Round and Round." Well, we heard that one too, but "Pioneer Germ Fighters" totally rules.
(Laughter) I loved to write from the age of four, and when I was six, my mom bought me my own laptop equipped with Microsoft Word. Thank you, Bill Gates, and thank you, Ma.
I don't know, you're kind of alienating a large client there. (Laughter) One publisher, Action Publishing, was willing to take that leap and trust me, and to listen to what I had to say.
Kids grow up and become adults just like you. (Laughter) Or just like you?
(Laughter) Adults and fellow TEDsters, you need to listen and learn from kids, and trust us and expect more from us. You must lend an ear today, because we are the leaders of tomorrow, which means we're going to take care of you when you're old and senile.
(Applause) Thank you. Thank you.
 We're on problem 21. In the figure below, n is a whole number.
I grew up on a steady diet of science fiction. In high school, I took a bus to school an hour each way every day. And I was always absorbed in a book, science fiction book, which took my mind to other worlds, and satisfied, in a narrative form, this insatiable sense of curiosity that I had.
And with "The Abyss," I was putting together my love of underwater and diving with filmmaking. So, you know, merging the two passions. Something interesting came out of "The Abyss," which was that to solve a specific narrative problem on that film, which was to create this kind of liquid water creature, we actually embraced computer generated animation, CG.
(Laughter) You know, I went and pitched it to the studio as "'Romeo and Juliet' on a ship:
"It's going to be this epic romance, passionate film." Secretly, what I wanted to do was I wanted to dive to the real wreck of "Titanic."
looking at the real Titanic through a view port. Not a movie, not HD -- for real. (Applause)
After the success of "Titanic," I said, "OK, I'm going to park my day job as a Hollywood movie maker, and I'm going to go be a full-time explorer for a while." And so, we started planning these expeditions.
I felt like I was physically present inside the shipwreck of Titanic.
And it was the most surreal kind of deja vu experience I've ever had, because I would know before I turned a corner what was going to be there before the lights of the vehicle actually revealed it, because I had walked the set for months when we were making the movie. And the set was based as an exact replica on the blueprints of the ship. So, it was this absolutely remarkable experience.
"What am I doing out here? Why am I doing this? What do I get out of it?"
People sort of think I went away between "Titanic" and "Avatar" and was buffing my nails someplace, sitting at the beach. Made all these films, made all these documentary films for a very limited audience. No fame, no glory, no money.
So, when I came back to make my next movie, which was "Avatar," I tried to apply that same principle of leadership, which is that you respect your team, and you earn their respect in return. And it really changed the dynamic.
So, here I was again with a small team, in uncharted territory, doing "Avatar," coming up with new technology that didn't exist before. Tremendously exciting. Tremendously challenging.
So one of the best ways to understand channels is to think about how business first started. We first started distributing and making physical products--cars, food, utilities, etc. and we distributed them through direct sales force--that is people you shook hands with, look in the eye and met. And it wasn't until the mid-20th century when we actually started selling virtual products-- things that didn't quite exist physically like insurance, stocks and bonds, enterprise softwares, shrinkwrap software start to be distributed through physical channels but they didn't exist in the real world.
that don't exist at all--Facebook, Twitter, Google--they're all bits, and they're also distributed via the web. This virtual virtual distribution channel allows for easier customerization, optimization, and allows you to change both product and channel almost on the fly. Through the rest of this lecture, we're going to show you which channels might be optimum for your startup and allow you to chose which one to pick.
So far we've learned what a complex number is; we've even learned how to graph it. And we learned how to add, subtract, and multiply it.

Welcome to the video on 'basic subtraction.' Let's do a little bit a review of 'basic addition' first. If I said '4 plus 3' (4 + 3), what would this mean?
4 minus 3 is equal to 1 and 4 minus 1 is equal to 3. You might say, well, did I pick the numbers just so it worked? Well, it turns out that it's always true.
3 plus 1 is equal to what? Well, that's easy. You know that from basic addition.
So I've been sent this definite integral problem and it seemed as good as any, and I think the key with this is just to see a lot of examples. So let's do it. This definite integral is from pi over 2 to pi of minus cosine squared of x times sin of x dx.
I want to do it however it is least confusing to you. OK let me erase that. Actually, let me do it with substitution, just because the way I was just doing is kind of my shortcut back in the day when I was a mathlete.
So now let's take the integral.
And now this is a very important thing. If you're going to do substitution, if we're going to say u is equal to cosine of x, we're going to have to actually make this substitution on the boundaries. Or we could do the substitution and reverse the substitution and then evaluate the boundaries, but let's do that.
This is pretty straightforward and I'm just going to rewrite it. What's cosine of pi?
Cosine of pi is minus 1.
Cosine of pi over 2, well that's a 0. So we have the integral from u is equal to 0 to u is equal to negative 1 of u squared du. And now this seems like a simple problem.
Well, the means should be exactly the same. So here it would be 7.5, and here 8.2. But the standard deviations are the population standard deviation divided by the square root of the sample size.
>> Now, in order to update the cx and cy offsets for trimmed sprites, we have to do a couple of interesting things. First off, you need to understand that [unknown] will only do a smart trim from the edges to the center. So, for instance, if you end up in a situation where you got a nice box and pixels in the top left quadrant, it won't actually trim that sprite because it can't shrink it to the center.

Welcome to this review of the installation procedure for Haas vertical machining centers start by walking around the machine and checking for any damage that may have occurred during shipping use a digital camera to document anything you find and notify the customer of your findings next, check that power and air are connected to the machine and that the connections are sized correctly local electrical code requirements dictate the size for the electrical service powering the machine machine power requirements are covered in the mill installation instructions and pre installation guide available online at haascnc.com these documents provide guidelines for the proper size cable for the particular machine configuration the airline must have an inner diameter of at least 1/2" or 13mm all the way from its source to the machine connecting the 1/2" hose directly to the hose barb with a hose clamp is preferred smaller fittings will significantly reduce the volume of air delivered and will hinder machine performance under demanding conditions with the appropriate power and air in place let's begin the machine installation process by disconnecting the shipping brackets from the doors remove all the accessory items
leave the lower packing layer between the enclosure panel and the pendant in place for now the control pendant weights approximately 80 lbs and you should ask for help from someone in the shop when lowering the pendant into position carefully bring the pendant to the top edge and make sure you are in a stable position in close proximity to the pendant before lowering it down slowly swing it out down clearing the enclosure be certain not to pinch any wires as the pendant is lowered into place align the pendant with the remaining front panel screw it can rest here momentarily while the shipping bolt is removed from between the pendant and the glove box insert the remaining screws and securely tighten all 6 screws back on the enclosure roof, insert the cable cover panel over the pendant pivot arm making sure not to pinch the wires coming from the pendant to the machine and tighten the panel screws using WD-40 or another pH neutral degreaser spray all way covers and other non painted surfaces that have been coated with Cosmoline
letting the WD-40 soak in while performing other tasks this will ease the removal of the Cosmoline a plastic scrapper can be used to remove particularly thick applications of Cosmoline do not use Scotch-Brite or metal scrappers as these will scratch the way covers note that none of the axis should be moved until all the Cosmoline has been removed this will avoid contamination of the way cover seals with a sticky residue apply pipe thread sealant to the blow off nozzle fitting and fasten it tightly to the lower front panel at the back of the machine open the air inlet valve to supply compressed air to the machine check that there are no air leaks and that the nozzle works correctly inside the machine, slide the auger onto the motor hub fasten the auger to the drive motor with a 5x16x18 bolt install the chip shoot next check the gasket alignment before exposing the adhesive surface peel back a small section of the gasket backing sheet and line up the holes slowly peel back the backing sheet while pressing the gasket against the flange while the WD-40 is softening the Cosmoline it's a good time to install accessories such as the tool holder tray and work table on the underside of the tool holder tray connect the work light power cable through the front enclosure panel zip tie any extra length of power cable neatly under the tray the tool holder vise is mounted to the outer end of the work table surface move to the rear control cabinet and check that the incoming power is balanced and that the transformer taps are set correctly using a multimeter at the main circuit breaker check the incoming voltage from phase to phase noting each of these values for later comparison
next, check the readings from phase to ground and record these values also
no phase to ground value should be larger than any of the phase to phase values a value that is too high likely indicates there is a bad or floating ground in the electrical service to the machine alert the customer what you found if the values are okay, switch the machine's circuit breaker to the off position and check that there is no voltage at the transformer using the average of the phase to phase voltage measurements just taken set the transformer tap position to match this average number
move to the T5 transformer and set the shorting plug to the range matching the transformer tap position just used now, switch on the machine's main breaker and move to the front control panel and press power on at the back of the machine, check that the wiring from the customer's service panel is in phase with the connections at the machine by checking that the phase indicating light is green a red light indicates the power is out of phase have the customer disconnect power at the service panel and lock out tag out or mark the breaker so that no one turns it on accidentally make sure to double check the incoming lines to ensure there is no voltage present before you swap the positions of the L1 and L2 lines at the circuit breaker after the machine has powered up and the control has initialized, you will see the machine activation screen write down the machine's serial number software version MAC address and the activation code retrieve the required key code by accessing the Haas portal from a computer at the portal, navigate a series of screens entering the machine information as you go when the information is entered you will receive the key code for activating the machine enter the key code and press write the machine will now function normally with the Cosmoline softened by the WD-40 it is ready for removal remove all visible signs of Cosmoline using shop towels to absorb all WD-40 and Cosmoline residue
leaving the machine clean with nothing left to contaminate the customer's coolant remove the screws from the shipping bracket
located between the spindle head and the machine table clip the zip ties that hold the flex tube tight to the shipping cradle now the Z-axis is free to move upwards at the control pendant, press zero return and then all the Z-axis will move upwards to clear the shipping cradle and the shipping bracket so they can be removed from the machine the machine used in our video example has the WlPS option installed and in this case, also remove the protective shipping bracket for the WlPS tool probe now we will begin the machine leveling process which achieves 3 things first, the machine is set at the correct height to clear the coolant tank second, the machine is rough leveled front to back and side to side finally, any twist or bow in the base casting is removed to ensure the machine will cut accurately the leveling process is covered in detail in an accompanying video available on the Haas portal with the machine geometry verified start the spindle warm up program press list program and then select the memory tab select program O0202 spindle warm up and press select program press cycle start and the spindle will begin turning at 500 RPM mention to the customer that it's good to run this program first thing in the morning anytime the machine has been sitting for more than a few days remove the protective film from the side windows the monitor the door handles and the enclosure entry edge protector now is a good time to install the coolant tank and its related components install the coolant tank handle onto the tank install the standard and TSC pumps and the gate filter is necessary remove the cover from the coolant level sensor jack insert the connector, and reinstall the cover cap before attaching the coolant level sensor to the coolant tank check that it registers the correct empty 1/2 full and full positions on the current commands page this will verify the sensor connection is good make the following connections between the machine the coolant pump hoses and the power cables attach the 3/4" coolant line from the coolant manifold to the standard coolant pump connect the power cord from the standard coolant pump to the receptacle labeled coolant if the machine is equipped with a TSC option connect the high pressure hose coming from the TSC pump to the high pressure filter on the machine connect the power cord for the TSC coolant pump attach the spray nozzle to the wash down hose and connect the hose to the mounting point on the enclosure when the coolant pump connections are complete ask the customer to fill the coolant tank so the connections that were just made can be tested for leaks while you are waiting for the customer to fill the coolant tank it's a good time to recheck the incoming voltages for fluctuations note the readings and compare them to your previous numbers variations should not be greater than plus or minus 5% when comparing your current values to those taken earlier if you note any fluctuations, let the customer know they may have some reason for concern in this video example, the 3 phase to phase and 3 phase to ground values are acceptable when the coolant tank is full, run each part of the coolant system to check that none of the connections are leaking use the machine's packing list to review the installed options for this machine and perform any installation steps required and check each option for proper function with the options checked, the spindle warm up program should be finished the installation is now complete and the machine is ready to run thank you for watching this review of Haas VMC installation process

Now the control tells me press [CYCLE START] to begin the probing routine
I've set G54 X and Y values, now I'm going to set Z I'm going to arrow to the left once so that I can select another template I'm going to choose Template 11.
"11" [WRlTE / ENTER] scroll to the right one time so I can enter the pertinent data I don't want any X or Y values but I'm going to be looking for the surface somewhere in the next half inch (0.5") in Z

And again, [CYCLE START] to begin the probing routine
Now that I've set my work offsets I'm ready to move on to the tool offsets Most of the tools for this job are already in the machine but I do have one new unique tool, tool 16, it's a shell mill So I'm going to go to Handle Jog mode and toggle through the
"Offset" pages until I can see the tool offsets Use the up and down arrows to get to tool 16 and then the right arrow to scroll across and fill in the information I need To do the automatic probing I need to tell the machine the number of flutes, three
Now that I've set all my offsets, I'm ready to begin cutting
Probing with the Haas machine is really that simple xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
All right, let's see if we can solve this problem. We're looking for our four clique. Now, four clique is going to have to have the property that each of the nodes is connected to each of the other nodes, so the alt degree or the degree of the node has to be at least 3.
Can you say a little bit about how social networks fit into the history of the use of technology in political protests? Right. This is a really an interesting topic in that with the dictators, what they want is a lot of people to believe that everybody is happy with what's going on.
Earlier we looked at the 4 phases of the entire customer development process, but now let's take a look at the customer discovery process itself and order its phases.
HTML5 can be used to create all sorts of engaging and dynamic applications. It's brought about an explosion of new browser features like rich graphics, device access and advance network connectivity.
In some sense the trend in web pages-- in the beginning it was only really technical people who could make their own webpages, and now it's getting easier and easier to just make use of sites that exist to put up a webpage of your own. Could you imagine social networking somehow going that way as well, where people can just try out and make their own little social networks just like blogs? So, people go on things like Twitter, because you have so many people you can actually mine information from.
Here we find our fun friend Phillip riding around on a delightful day. Phillip just loves his Twitter. Ohhh, but there's a problem!

Let's see if we can learn a thing or two about partial fraction expansion, or sometimes it's called partial fraction decomposition.
The whole idea is to take rational functions-- and a rational function is just a function or expression where it's one expression divided by another-- and to essentially expand them or decompose them into simpler parts. And the first thing you've got to do, before you can even start the actual partial fraction expansion process, is to make sure that the numerator has a lower degree than the denominator. In the situation, the problem, that I've drawn right here,
If x is equal to 8, you get x plus 3 is equal to 11, is equal to a times 0 plus b times-- what's 5-- 8 plus 5 is-- plus b times 13. Their b looks a bit like a 13. And then you get 11 is equal to 13b, divide both sides by 13, you get b is equal to 11 over 13.
So one extremely important operation in analyzing social networks is finding the shortest path between individuals in the graph-- not generally because we need the actual path but because we want to have some sense of how closely connected different pieces of the graph are.
But the pairwise shortest path problem is of independent interest. It's actually kind of fun and interesting to see essentially what allows Google Maps or MapQuest or Yahoo Maps to plot shortest paths for you to drive. But another kind of whimsical version of this problem is the Kevin Bacon game.
Well, the other interesting things that we have the teams do, and the JerseySquare guys was a great example, is to the start to put together the unit economics, the metrics that matter for both revenue and cost. So, then we're going to take the annual subscription revenue, $199, and see what their business looks like. So they assumed that the cost of a jersey with 25% off to them, that is, to JerseySquare was $150.
[Mooji] How will silence watch? How is everything watched?
And I should know what you're talking about.' No. If you want to know what they're talking about, you have to go to a dream-language school, in your dream, to study the alphabet of this people, and learn their language.
Some are telling you, 'Even from this one you must wake up!' What can it mean? What could it possibly mean to wake up from this?
The question is, who is the dreamer? What watches this dream? Even some people don't say it's a dream.
Okay, here's an example of a decision problem that comes up in social network analysis and that's the clique problem. Remember clique is a set of nodes in a network that are all pairwise connected-- everybody in the group knows everybody else in the group. We were given a graph G and a number k, let's say 4, and we're asked--is there a clique of size k in G.
So I have several groups of these ball-looking things and let's think about how many balls are in each group. We have:
1 2 3 4 5 6 7 8 9 10 11 12. And what I want to do is think about the different ways of dividing these 12 balls into different numbers of groups. So, for example, I could view these 12 balls as:
1...so that's 1 group of 3, 2 groups of 3, 3 groups of 3, 4 groups of 3. So I could view 12 as being 4 groups of 3.
And the way that we would write that... the way that we would write that... is that 12...is that 12 is equal to 4 groups of 3... ...4 groups of 3.
Or another way of reading this is that 12 is equal to 4 times 3. If I have 1, 2, 3, 4 groups, and in each of those groups I have 1, 2, 3 objects... I'm going to have a total of 12 objects.
1, 1 group of 4, 2 groups of 4, 3 groups...3 groups of four. So now we could view 12 as being 3 groups of 4. Or we could say, we could say that 3... (let me get the right tool out) ...we can say that 3, 3 times 4... ...3 times 4 is equal to 12.
We could write 6 times 2, 6...6 groups of 2, 6 times 2 is also...is also equal 12. But we don't have to stop there. We could also literally view 12 as 1 group of 12.
1...1 group...1 group of 12 here. So we could literally say 1...1 times 12...
1 times 12 is equal to 12. We have 1 entire group of 12, 1 times 12 is equal to 12. And we could think of it the other way around.
Let me draw that. So 12 groups of 1. This is 1 group of 1, 2 groups of 1, 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12.
Round 1,585 to the nearest ten. Let me rewrite the number. 1,585 to the nearest ten.
So we covered a lot of material in the customer segment part of the business model canvas. We talked about the jobs to be done. We talked about pains.
So an additional help in thinking about your value proposition comes from a great VC, Ann Miura-Ko, at Floodgate. Ann said, "We can think of startups' value propositions of having 2 forms." "Do they have technology insight, or are they market insights?"
Welcome back. In the last video, I told you that pressure times volume is a constant. That if you increase the pressure-- or if you increase the volume, you're going to decrease the pressure.
Now and then I think of when they were together. Like when you found a route that went from X to Y All those paths, they went through A and B, which isolates them from that whole subtree.
That can use two nodes. Now there's just no pathway that can use two nodes [No pathways]
That can use two nodes [No pathways]
Now there's just no pathway that can use two nodes [No pathways]
That can use two nodes That can use two nodes. That can use two nodes

Welcome back. I'm now going to do some more examples of a bit of a review of some of the derivatives that we've been seeing. And then I'll introduce you to something called the chain rule which expands the universe of the types of functions we can take the derivatives of.
So in the last presentation, I showed you how to function if I had f of x is equal to 10x to the seventh plus 6x to the third plus 15x minus x to the 16th. To take the derivative of this entire function, we take just the derivatives of each of the pieces, right? Because you can add them up.
So, one of the wonderful things about depth-first search is that it can be implemented really straightforwardly with recursion, which makes it very easy to read and pretty easy to reason about. Not so with breadth-first search. Breadth-first search is going to require a little bit more care to implement it in a way that keeps track of things in the right order.
Instead of recursion, it just has this open list to keep track of things. All right--here's another graph that we're going to search and this is going to help us illustrate the difference between depth-first search and breadth-first search. So, what we're going to do is we're going to start a search from v and let's see how it proceeds.
V is already marked. Y is not. Add y to our open list.
Y says we have to check x and z, those are the neighbors.
Z has already been marked and x is not. Take care of x and then just as before and now that everything is marked, it's going to end up popping this off the open list and it finishes. Let's look at the order in which nodes were marked.

The disrespect or faults that have happened towards Religions, Religious Leaders, or Religious Followers We may have knowingly or unknowingly been disrespectful (viradhna) towards any religion, religious sect, its religious beliefs, for its teachers (guru's), the Gods of that religion the deities of that religion (dev-devio), or its followers. Sometimes it comes in the newspapers or at a social gathering with friends there is gossip about how a certain saint did this or that, that he had illicit relations or fell into the pit of money or sensual pleasures, or for some land or property, or money.
And the goal of all this is to actually define the customer persona or archetype, which is just a fancy way for saying I want you to know everything about those customers. What could be everything?
You could almost imagine that there's a conversation going on between a psychic and a detective to solve a murder mystery. The detective is at a dead end and can't figure out how to solve the murder mystery and the psychic has this sort of amazing leap--oh, you need to check the finger prints on the body. This maybe not that amazing of a leap and you'll find that the murderer is Smith.
I've talked a lot about using polynomials to appro, approximate functions. But what I wanna do in this video is actually show you that the approximation is actually happening.
Just a few lines of code. Create a new XMLHttpRequest object like before. We call request.open again, pretty much the same except that we've changed weapon.jsan to bgmenu.ogg, and we set request.responseType to be arraybuffer.
Welcome to the presentation on adding and subtracting fractions. Let's get started. Let's start with what I hope shouldn't confuse you too much.
It's the same thing as ten over ten, right? ten over ten is one. So one tenth minus ten over ten is the same thing as one minus ten-- remember, we only subtract the numerators, and we keep the denominator ten, and that equals negative nine over ten. one tenth minus one is equal to negative nine over ten. Let's do another one.
Well the least common multiple of nine and four is thirty-six. So that's equal to thirty-six. So what's negative one ninth where we change the denominator from nine to thirty-six?

When you are thirteen and a half years old, you need to be learning negative numbers. [Salman Khan]
[Founder, Khan Academy]
When you are fourteen, you need to be learning exponents. That's silly. You need to be learning exponents once you really understand multiplication.
And you need to be learning negative numbers once you really understand the number line.
Once you get rid of the stigma and you open it up and everyone's a learner and everyone's just on the same playing field, I, it actually is empowering for everyone.
I have a two-year old son, Imran,and, obviously I care about what his academic experience [the future of learning] is going to look like, and I'm hoping that when he's five or six, he goes to a classroom that not only has five or six-year olds in it, but it has kids of all ages in that one classroom.
It's kind of a reversion back to the one-room schoolhouse, and when he goes to that classroom, some part of his day, and I'm not talking about the whole day, maybe twenty to thirty minutes of the day, especially for the core subjects, are spent on the Khan Academy, watching videos, and by that time, it won't be just Mathematics and Science, it will be grammar, it will be vocabulary.
["the slope of this orange line"]
He starts at the most basic concepts, he doesn't move on to more advanced concepts until he shows that he is 110% proficient at the more basic ones [mastery] and then it moves him on, and he gets data, and he gets feedback, and his teachers gets feedback, and the paradigm is all of these students at all of different ages, they're all going to be working at their own pace in every class, in grammar, in mathematics, in everything.
The teacher now, instead of having to give this one size fits all lecture to everybody, can now look at the data, and see where every students is, and the software identifies who's stuck.
The teacher, every now and then, will sit next to Imran and help Imran as a mentor, and actually have that human interaction. And, even better, the teacher isn't around. If the teacher is around, it may be better for Imran to be tutored by one of his peers.
Is the proportion true or false that 3/12 or 3:12 is equal to 5/35 or 5:35? Now to figure this out, we just have to figure out whether these are equivalent fractions, and the easiest way to do that, is to put both of them in simplified form, and see if we get the same answer. So let's try with 3/12 first.
What is going on in this baby's mind? If you'd asked people this 30 years ago, most people, including psychologists, would have said that this baby was irrational, illogical, egocentric -- that he couldn't take the perspective of another person or understand cause and effect. In the last 20 years, developmental science has completely overturned that picture.
"Can you give me some?" So the question is: What would the baby give her, what they liked or what she liked?
"A slingshot or maybe a spear might work. Which would actually be better?" You want to know all that before the mastodons actually show up.
(Laughter) Boy: This one lighted up, and this one nothing.
Maybe your product requires a physical distribution channel. Let's take a look at all the choices that you might have when you start a company. The first one is you might be an OEM.
I'm going to talk about an algorithm called Floyd Warshall after two of the inventors of this algorithm back in the early 60s, and it uses an idea called dynamic programming, which sounds so much cooler than its actually is. That means, it actually is a very cool idea. I have a professor friend who believes that I am predispose to see all problems at dynamic programming problems because it an algorithm design technique that I have been able to use successfully in a bunch of occasion, but it really is just an algorithm design technique.
The ij element of the i row, j column is filled in with the number and that number is the length of the shortest path from i to j hopping only all nodes numbered less than k. So I don't know about you but I used to play a game like this when I was younger, if I was in a building where the tiles were different colors, I'd sometimes declare let's say, the blue tiles are alligators, so I'm not going to step on any of the blue tiles and I'd try to walk stepping only on the tiles that I was allowed to use, so that the analogue of this in the graph is imagine we've got our graph, and we're trying to get a path from i to j, and some of the nodes are colored pink.
Use the associative law of addition to write the expression. We have a 77 plus 2 in parentheses, plus 3, in a different way. Simplify both expressions to show they have identical results.
And 79 plus 3 is 82, so this is equal to 82. That's if you just evaluate it the way that they gave it to us. Now, the associative law of addition tells us it doesn't matter whether we add 77 and 2 first or whether we add 2 and 3 first.
77 plus 2 plus 3. If we have no parentheses here, this is actually the same thing as this over here, because we'd go 77 plus 2 is 79 plus 3 is 82. But the associative law tells as, well, you know what?
So 2 plus 3 is 5, so this evaluates to 77 plus 5.
And 77 plus 5, once again, is 82. So it doesn't matter how you associate the numbers. Either way, you get 82.
What did we use to believe on how you physically build a startup? What was the process we used? We used to build startups by managing processes.
In fact for 30-40 years this was the canonical model for how to build startups and we'd say marketing, well, we understand. While engineering is developing the product, marketing is creating all the marketing communications material, hiring a PR agency, and creating early buzz and then from marketing the world's most fun job was have the party. You get to create demand by having a launch event and you think about branding and your job really was to create end-user demand and derive it into the potential sales channel.
I think I'll start out and just talk a little bit about what exactly autism is. Autism is a very big continuum that goes from very severe -- the child remains non-verbal -- all the way up to brilliant scientists and engineers. And I actually feel at home here, because there's a lot of autism genetics here.
And I was shocked to find out that my thinking was quite different. Like if I say, "Think about a church steeple" most people get this sort of generalized generic one.
"Well, we're designing a software for a phone and it has to do some specific thing. And it can only use so much memory." That's the kind of specificity you need.
"If by some magic, autism had been eradicated from the face of the Earth, then men would still be socializing in front of a wood fire at the entrance to a cave." Temple Grandin: Because who do you think made the first stone spears?
"My kid went to college because of your book, or one of your lectures," that makes me happy. You know, the slaughter plants, I've worked with them in the '80s; they were absolutely awful. I developed a really simple scoring system for slaughter plants where you just measure outcomes:
CA: Temple, can I just say it's an absolute delight to have you at TED.
TG: Well thank you so much. Thank you.
I think it'd be a good idea to practice with this algorithm a little bit to get better into your head. Let's say that we're going to try to find the shortest path from A to F in this graph and we're going to use the algorithm that we were kind of sketching out together on the previous line. As you recall, what is does is it does a kind of breadth-first search from A but instead of expanding nodes at the bottom of the tree it always expands the node that has the smallest number written in the node.
78 is 15% of what number? So there's some unknown number out there, and if we take 15% of that number, we will get 78. So let's just call that unknown number x.
Now, 15% mathematically, you can deal directly with percentages, but it's much easier if it's written as a decimal. And we know that 15% is the same thing as 15 per 100. That's literally per cent.
15 does not go into 7, So you could do it zero times and you can do all that, or you can just say, OK, that's not going to give us anything. So then how many times does 15 go into 78? So let's think about it.
15 goes into 60 four times.
15 times 5 is 75. That looks about right, so we say five times.
5 times 15.
5 times 5 is 25.
Put the 2 up there.
5 times 1 is 5, plus 2 is 7.
75, you subtract.
78 minus 75 five is 3.
Bring down a zero.
15 goes into 30 exactly two times.
2 times 15 is 30. Subtract. No remainder.
15 goes into 0 zero times.
0 times 15 is 0. Subtract. No remainder.
520, or what number before we figured out it was 520, that's what we're taking the percentage of. This is sometimes referred to as the base. That is the base.
78 is exactly 15% of 520.
I am very, very happy to be amidst some of the most -- the lights are really disturbing my eyes and they're reflecting on my glasses. I am very happy and honored to be amidst very, very innovative and intelligent people. I have listened to the three previous speakers, and guess what happened?
(Laughter) But there is a saying in my culture that if a bud leaves a tree without saying something, that bud is a young one. So, I will -- since I am not young and am very old,
They are entrepreneurs. [Unclear] told us they are always about four percent of the population, but 16 percent are imitators. But they also succeed at the job of entrepreneurship.

Many countries in the [unclear], they need legitimacy. To get legitimacy, governments often need to deliver things like primary education, primary health, roads, build hospitals and clinics. If the government's fiscal survival depends on it having to raise money from its own people, such a government is driven by self-interest to govern in a more enlightened fashion.
Ghanaian businessmen, South African enterprising leaders, our governments find it more productive to talk to the IMF and the World Bank. I can tell you, even if you have ten Ph.Ds., you can never beat Bill Gates in understanding the computer industry. Why?
The IMF, the World Bank, and the cartel of good intentions in the world has taken over our rights as citizens, and therefore what our governments are doing, because they depend on aid, is to listen to international creditors rather than their own citizens. But I want to put a caveat on my argument, and that caveat is that it is not true that aid is always destructive. Some aid may have built a hospital, fed a hungry village.
Between 1960 and 2003, our continent received 600 billion dollars of aid, and we are still told that there is a lot of poverty in Africa. Where has all the aid gone? I want to use the example of my own country, called Uganda, and the kind of structure of incentives that aid has brought there.
In the 2006-2007 budget, expected revenue: 2.5 trillion shillings. The expected foreign aid:
1.9 trillion. Uganda's recurrent expenditure -- by recurrent what do I mean? Hand-to-mouth is 2.6 trillion.
70 cabinet ministers, 114 presidential advisers, by the way, who never see the president, except on television.
(Laughter) (Applause) And when they see him physically, it is at public functions like this, and even there, it is him who advises them.
(Laughter) We have 81 units of local government. Each local government is organized like the central government -- a bureaucracy, a cabinet, a parliament, and so many jobs for the political hangers-on.
Three hundred thirty-three members of parliament. You need Wembley Stadium to host our parliament.
One hundred thirty-four commissions and semi-autonomous government bodies, all of which have directors and the cars. And the final thing, this is addressed to Mr. Bono. In his work, he may help us on this.
(Laughter) Thank you very much.
(Applause)
Here's the strategy that I would suggest. There's probably a couple of different ways to do this. We could take the original graph that we know there is some length I path, simple path from U to V and what we can do is for each edge in the graph say, well, what if we delete that edge?
With this kind of star network in particular, the datastructure that you need to set up is actually quite simple. We need to be able to compute the distance between any pair of nodes called say a which is labelled here in the graph, and b labelled here in the graph and they have to have lists of hubs such that the uh... the hub has to be on a shortest path from a to b, well all the paths from a to b in fact all the paths between anything in the network have to pass through x so as long as everybody has their distance to x which is 1 if it's an unweighed network but there could be weights on these edges as long as each node knows its distance to x we'll be able to intersect the lists for any pair of nodes and know the total distance from node a to node b. uh... one little bit of trickiness there though is that notice that x's list also has to have x on it but that's ok. It can just have x with a distance of zero so it can be its own hub and then we still should be fine we'll get the distance from a to x which is whatever the distance from a to x is plus zero so one is the answer I was looking for.
Let's think a little bit about what happened in the last video. I'll review again these different notions of money supply. And then let's talk about whether it's fair for people to think that they really have the money that they have
But then I take the builder's money, and I said, well, you know, this banking idea's a new idea to me. I'm just going to leave it all as reserves. I want to see how it all plays out first.
In M0 we said -- we'll call this our narrowest definition. And this is literally, how much gold is there in the system. Or how much stuff is there in the system that could be immediately used for conducting a transaction.
I actually have very little cash in my wallet right now, if any of you are thinking of mugging me.
All of my money is in a checking account. So if someone asked me how much money do you have, I'd give that number.
So if you went around the town, and you asked everyone, how much money do you have, and you added it up, you would get the total of the of their checking accounts. And so we had 810 gold pieces from the contractors, 900 gold pieces from the ditch diggers, and then 1,000 gold pieces from the farmers. Let's see, 1,900 plus 810.
So next, we're going to extend this idea of finding a path from V₁ to V₂ to the idea of finding a shortest path from V₁ to all other nodes. And one of the reasons we want to do that is to identify central node in a social network. Nodes that are likely to have a lot of influence, or well-placed, or very well-connected, and so we're going to look now at the question of given a node V₁, how central is it?
At the end of that process, every single node in the graph will have a shortest path from the--will be notated, annotated with the shortest path from V₁ to that node. So, the running time here is just the time it takes to do a single search,
Θ(n+m) and then you get the answer for all the nodes in the graph.
What is the perimeter of the shape? Each square in the grid is a one by one centimeter square. So, all we have to do is add up the lengths of these blue segments, right over here.
So let's take a look at our Jersey Square team and see what they've done with channels. By the time they've gotten to this part in the canvas, they've actually recognized that besides working on channels they actually have two distinct customer segments, sport jersey owners and single-game attendees. And just if you remember, by the time you understand you have multiple segments, that means you need multiple value propositions and multiple revenue streams.
 Let's see if we can apply some of our new tools to solve some line integrals.
Before we go into the details of the Cuban Missile Crisis, it's important to understand the world's environment entering into October of 1962.
And he is heading the Communist party there.
This is the middle of the Cold War. The U.S. believes in a strategy of containment, does not like this. So in 1961, the United States, the ClA, the Kennedy Administration, they try using Cuban exiles, people who have left Cuba, they try to support them to enter and invade Cuba at the Bay of Pigs.
>>> Ladies and gentlemen, please welcome Senior Vice President, Vic Gundotra.
[ Cheers and applause ] >>Vic Gundotra:
In society, we have to follow laws that maintain order. Did you know all chemical matter follows certain laws as well? In fact, we can describe those laws by looking at relationships.
 Let's try to get a better intuition of the chain rule, and in the process, we'll get a better intuition of how it applies to implicit differentiation or vice versa. So let's say-- and I'm going to get out of the world of x's and y's and f of x's for a second, just so that you see that those are just letters and there's nothing special about them.
We have a defined in terms of b, so it's not like we can just take the derivative. I mean, how do we do that? Well, that's where the chain rule comes in.
And so we're done. The derivative of a with respect to c is equal to this, which is this, 2b, the derivative of a with respect to b times the derivative of b with respect to c. So times cosine of c.
Why you're doing all this is to define the minimum viable product, or sometimes called the MVP for short.
The MVP basically is what product or service you're building in your first instance that's delivered to customers. And the MVP is not an alpha or beta. This is a big idea.
The MVP says, "No, no, no. We're not spec'ing a version 1.0 product

"and trying to understand what's the minimum version of a version 1.0--
"not what engineering or the founders thought
"but what is it customers are going to tell us they'll pay for or use now?" And while it might be, quote, a beta product, we never use that word. We actually tell customers it's a minimum viable product.
I'd like to take you to another world. And I'd like to share a 45 year-old love story with the poor, living on less than one dollar a day.
"I'd like to live and work in a village." Mother went into a coma. (Laughter)
"What is this? The whole world is laid out for you, the best jobs are laid out for you, and you want to go and work in a village? I mean, is there something wrong with you?"
"What do you want to do in a village? No job, no money, no security, no prospect." I said, "I want to live and dig wells for five years."
"Dig wells for five years? You went to the most expensive school and college in India, and you want to dig wells for five years?" She didn't speak to me for a very long time, because she thought I'd let my family down.
"You failed in your exam?" I said, "No."
"You didn't get a government job?" I said, "No."
"What are you doing here? Why are you here? The education system in India makes you look at Paris and New Delhi and Zurich; what are you doing in this village?
"You build this, you build this, you put this, and it'll work." This is what it looks like today. Went to the roof, and all the women said, "Clear out.
You have Jokhim Chacha who is 300 years old. He is my psychoanalyst. He is my teacher.
"What was the benefit you had from solar electricity?" And she thought for a minute and said,
"It's the first time I can see my husband's face in winter." (Laughter) Went to Afghanistan.
(Laughter) (Applause) So we went to Afghanistan for the first time, and we picked three women and said, "We want to take them to India." They don't even go out of their rooms, and you want to take them to India."
"Grandmothers?" The minister couldn't believe what was happening.
"Where did they go?" "Went to India and back." Went straight to the president. He said, "Do you know there's a solar-electrified village in Sierra Leone?"
"What's the story." So he summoned me and said, "Can you train me 150 grandmothers?" I said, "I can't, Mr. President.
"Difficult husband; not possible." Called the husband, the husband came, swaggering, politician, mobile in his hand. "Not possible."
"Why not?" "The woman, look how beautiful she is." I said, "Yeah, she is very beautiful."
"What happens if she runs off with an Indian man?" That was his biggest fear. I said, "She'll be happy.
"First they ignore you, then they laugh at you, then they fight you, and then you win." Thank you. (Applause)
All right, so let's think this through, what's going on here. So going back to the formula for a second. Remember all the clauses end up being in these groups, so there's one clause for each node that says that that node has to have one of the k colors.
Okay.

The answer is product market fit--finding the right balance between the minimum level of viable product and the customer archetypes.
A virus, or viruses.
And in my opinion, viruses are, on some level, the most fascinating thing in all of biology. Because they really blur the boundary between what is an inanimate object and what is life?
I mean if we look at ourselves, or life as one of those things that you know it when you see it. If you see something that, it's born, it grows, it's constantly changing. Maybe it moves around.
And the genetic information can come in any form. So it can be an RNA, it could be DNA, it could be single-stranded RNA, double-stranded RNA.
And not all viruses have to look exactly like this. There's thousands of types of viruses.
We'll talk more about that in the future.
And inside they have some genetic material, which might be DNA or it might be RNA. So let me draw their genetic material. The protein is not necessarily transparent, but if it was, you would see some genetic material inside of there.
So let me draw this thing a little bit smaller. So let's say that this is my virus. I'll draw it as a little hexagon.
Let me draw the cell here. Cells are usually far larger than the virus.
Now, that's one method.
I'll just talk about that.
The viruses don't even enter the cell.
But that's beside the point.
We just haven't found them.
And I talk about that in a different video.
And then once there's enough of these and the cell has essentially all of its resources have been depleted, the viruses, these individual new viruses that have replicated themselves using all of the cell's mechanisms, will find some way to exit the cell.
Let me write that down.
And what you see emerging from the surface, essentially budding from the surface of this white blood cell-- and this gives you a sense of scale too-- these are HlV-1 viruses.
And so you're familiar with the terminology, the HlV is a virus that infects white blood cells.
And it's hard.
If you think that these are exotic things that exist for things like HlV or Ebola , which they do cause, or SARS, you're right. But they're also common things. I mean, I said at the beginning of this video that I have a cold.
So they're with us all around.
And it's not doing anything. And that doesn't look like life to me. It's not moving around.
But hopefully this gives you a good idea of what viruses are and why they really are, in my mind, the most fascinating pseudo organism in all of biology.
We all know the scene: Dorothy closes her eyes, and repeats the Good Witch's mantra,
"No coordinates exist like one's domicile, no coordinates exist like one's domicile, no coordinates exist like one's domicile." Only Dorothy doesn't say that. She says five one-syilable words,
"There's no place like home." Each a word you probably learned in your first year of speaking, each perfectly concise. It's not that L. Frank Baum didn't have a thesaurus, it's that in most cases $10 words fail.
"Ambulate This Direction?" Probably not. Would Patrick Henry have ignited a revolution by saying,
(Lakshmi Pratury)This session is going to be a little different because, Mansukhbhai wants to speak in hindi. So, we're going to have a little conversation. And I will do the best to translate it.
(Applause) (Mansukhbhai) After this I made a cooker, today the food that we eat, we eat it only to fill our stomachs but what our ancestors used to eat our great grandfathers used to eat made them very healthy.
They used to never get a number for their eye, for a long time their hair never became white What is the main reason for this? That the orignal elements that are in it, they stay.
Inside, the air will be cool without a fan When we come from outside inside our fridge the temperature is of 20 degree Celsius, so we will build a home, a cool home that will have a temperature Of 20 degree Celsius. This is our new thought.
(Applause) (MP) Thank you thank you thank you.
(Applause)
Let's start with a warm-up problem to avoid getting any mental cramps as we learn new things. So this is a problem that hopefully, if you understood what we did in the last video, you can kind of understand what we're about to do right now. And I'm going to escalate it even more.
Four times nine is equal to thirty-six. Right? Eighteen times two.
Yep, thirty-six. So we write the six down here, carry the three up there.
Just put the three up there, then you got four times two.
Four times two. And they're going to have to add the three. So let me just write that there.
Four times three. You got that one up there, so you're going to have to add that plus one is equal to-- that's going to equal twelve plus one, which is equal to thirteen. So it's thirteen.
Four times four. You have this little one hanging out here from the previous multiplications, so you're going to have to add that. And that's equal to sixteen plus one.
Four times six, plus one. What is that?
Four times six is twenty-four. Plus one is twenty-five.
Put the five down here.
There's no where to put the two-- there's no more multiplications to do-- so we just put the two down there. So sixty-four thousand three hundred twenty-nine times four is two hundred fifty-seven thousand three hundred sixteen. And in case you're wondering, these commas don't mean much.
I'm going to put a two-digit number. So times twenty-three. So you start off doing this problem exactly the way you would have done it if there was just a three down here.
Three times three is nine. Plus one, so three times three plus one is equal to-- that's nine plus one is equal to ten. So you put the ten there.
Two times six. That's easy. That's twelve.
Put the one up here. And I got rid of the previous one because that would've just messed me up. Now I have two times three.
Two times three is equal to six. But then I have this plus one up here, so I have to add plus one. So I get seven.
Two times three plus one is equal to seven. So this seven hundred twenty we just solved, that's literally-- let me write that down.
Thirty-six times twenty is equal to seven hundred twenty. And hopefully that should explain why we had to throw this zero here. If we didn't throw that zero here we would have just a two-- we would just have a seventy-two here, instead of seven hundred twenty.
Zero plus two is two.
One plus seven is eight. So thirty-six times twenty-three is eight hundred twenty-eight. Now you're saying, Sal, why did that work?
Eight hundred twenty-eight? Is that what we got? We got eight hundred twenty-eight.
Three times six is eighteen.
Eighteen is just ten plus eight. So it's eight, then we put a ten up here. And ignore all this up here.
Three times thirty.
Three times thirty is ninety.
Ninety plus ten is one hundred. So one hundred is zero tens plus one hundred. I don't know if this confuses you or not.
Twenty times six is one hundred twenty. So that's twenty plus one hundred. So I'll put that one hundred up here.
Twenty times thirty-- you might not know-- is two times three and you have two zeros there. And I think I'm maybe jumping the gun a little bit, assuming a little bit too much of what you may or may not know. But twenty times thirty is going to be six hundred.
One hundred plus seven hundred. Plus twenty plus eight, which is equal to eight hundred twenty-eight. My point here is to show you why that system we did worked.
Seventy-seven times seventy-seven. Seven times seven is forty-nine.
Put the four up here. Seven times seven, well, that's forty-nine. Plus four is fifty-three.
There's no where to put the five, so we put it down here.
Seven times seven is forty-nine. Plus four is fifty-three. Stick a zero here.
Seven times seven is forty-nine. Stick a nine there. Put a four there.
Seven times seven is forty-nine. Plus four, which is fifty-three. So notice, when we multiplied seven times seventy-seven we got five hundred thirty-nine.
Nine plus zero is nine.
Three plus nine is twelve. Carry the one.
One plus five is six.
Six plus three is nine. And then we have this five. So it's five thousand nine hundred twenty-nine.
Now, let's do something pretty interesting, this in some degree will be one of the easiest functions to find the maclaurin series representation of
Now we keep using the words get, keep, and grow, but this get, keep, and grow actually refers to human beings not just random ideas. And one of the things we need to understand is what's the archetype or the persona of our customers that we're actually wanting to get and so one of the things that's kind of hard for startups is to realize that getting customers isn't some abstract idea-- you really need to understand who your customers are and this is not just thinking about selling to consumers. Even in corporations, there are human beings with titles that you need to figure out almost the same things as you would in a consumer company.
Welcome to the presentation on dividing decimals. Let's get started with a problem. If I were to say, how many times does point two eight go into twenty-three point eight two eight?
How many times does twenty-eight go into twenty-three? Once again, still, it goes into it zero times, because twenty-three is smaller than twenty-eight. How many times does twenty-eight go into two hundred thirty-eight?
Twenty-eight is almost thirty.
Two hundred thirty-eight is almost two hundred forty. So thirty goes into two hundred forty eight times, because three goes into twenty-four eight times. So I'm going to guess that twenty-eight goes into two hundred thirty-eight eight times.
Eight times two is sixteen. Plus two is twenty-two. Subtract.
Once again, you recognize this is just purely a level two division problem-- a level four division problem. So now I say, how many times does twenty-eight go into one hundred forty-two? Well, once again, I'm going to approximate.
Twenty-eight, it's almost thirty. Let's see, thirty times four is one hundred twenty. So yeah, I'll take a guess and I'll say
Four times eight is thirty-two. And four times two is eight. Plus three is eleven.
Two minus two is zero. Four minus one is three. Huh!
Five times eight is forty.
Five times two is ten. Plus four is fourteen.
One hundred forty-two minus one hundred forty is two. Good!
Two is less than twenty-eight.
This five is correct. Now I just bring down the eight.
Twenty-eight goes into twenty-eight exactly one time. One times twenty-eight is twenty-eight, remainder of zero. Done!
So twenty-eight goes into two thousand three hundred eighty-two point eight, eighty-five point one times. Or you could say, point two eight goes into twenty-three point eight two eight, eighty-five point one times. That's the answer we had gotten.
Point two eight is almost one third. So twenty-three is almost one third of eighty-five. So at least it makes sense in rough numbers.
Thirty-three goes into forty-three one time. That's easy. One times thirty-three is thirty-three.
Forty-three minus thirty-three is ten. Bring down this two. Thirty-three goes into one hundred two?
Three times thirty-three is ninety-nine.
One hundred two minus ninety-nine? Well, that's easy. That's three.
Thirty-three goes into thirty-three one time. One times thirty-three is thirty-three. Minus thirty-three, zero.
So how many times does twenty-five go into three?
Well zero. So you could put a zero here just for fun if you want.
How many times does twenty-five go into thirty-three? Well, it goes into it one time.
One times twenty-five is twenty-five.
Thirty-three minus twenty-five is eight. Bring down the five.
Twenty-five goes into eighty-five? Well, we know twenty-five times three is seventy-five. So it'll go into it three times.
Three times twenty-five, we know that's seventy-five.
Eighty-five minus seventy-five is ten.
Bring down the zero. Up here we had brought down the five before. And twenty-five goes into one hundred, four times.
Here's our last random graph of this unit. We're going to again generate a graph on n nodes recursively. Same structure as before.
Write 2.75 as a simplified fraction. So once you get some practice here. You're going to find it pretty straightforward to do.
100 is divisible by both 100 and 10. So let's get this 10 to be a 100. So we can do that by multiplying it by 10.
70 plus 5 is 75.
And our denominator is 100, so this can be rewritten as 2 and 75/100. And we saw that in the last video, you would read this as two and seventy-five hundredths. Now, we aren't in a completely simplified fraction yet because 75 and 100 have common factors.
Three quarters is $0.75, four quarters is 100 cents, or four quarters is $1.00. So you divide both of them by 25. So 75 divided by 25 is 3, and 100 divided by 25 is 4.
In this segment, I want to give a few examples of stream ciphers that are used in practice. I'm gonna start with two old examples that actually are not supposed to be used in new systems. But nevertheless, they're still fairly widely used, and so I just want to mention the names so that you're familiar with these concepts.
So the first one is, it's kind of bizarre basically, if you look at the second byte of the output of RC4. It turns out the second byte is slightly biased. If RC4 was completely random, the probability that the second byte happens to be equal to zero would be exactly one over 256.
It so happens that for RC4 the probability is actually two over 256, which means that if you use the RC4 output to encrypt a message the second byte is likely to not be encrypted at all. In other words it'll be XOR-ed with zero with twice the probability that it's supposed to. So two over 256, instead of one over 256.
RC4. But nevertheless, this is something that can be used to predict the generator and definitely it can be used to distinguish the output of the generator from a truly random sequence. Basically the fact that zero, zero appears more often than it should is the distinguisher.
loaded into the initial state of the LFSR. You can see that the first two bytes are sixteen bits, plus leading one, that's seventeen bits overall, whereas the second
LFSR is 24 bits plus one which is 25 bits. And you notice we used all five bits of the key. So then these LFSRs are basically run for eight cycles, so they generate eight bits of output.
XOR these two things together, so in other words, you do the XOR here, what you'll get is the initial segment of the PRG. So, you'll get the first twenty bytes of the output of CSS, the output of this PRG. Okay, so now here's what we're going to do.
LFSR. Okay? So two to the seventeen possible values.
LFSR for twenty bytes, okay? So we'll generate twenty bytes of outputs from this first LFSR, assuming—for each one of the two to the seventeen possible settings. Now, remember we have the full output of the CSS system.
PRG takes as input both the key and the nonce. And the property of the nonce is that the pair, k comma r, so the key comma the nonce, is never—never repeats. It's never used more than once.
You realize that some stream ciphers are designed for software, like RC4.
When we park in a big parking lot, how do we remember where we parked our car? Here's the problem facing Homer. And we're going to try to understand what's happening in his brain.
"Where am I now within my environment?" Place cells are also being recorded in humans. So epilepsy patients sometimes need the electrical activity in their brain monitoring.
Find the perimeter of this hexagon. So the perimeter just means the distance around the object, or if you add up all of the lengths of the sides of the object, so we're going to add up all of the lengths of sides of this hexagon, and a hexagon is just a six-sided geometrical shape like this. So to find the perimeter, we just need to find the distance around the hexagon, which is going to be the sum of all of the lengths of the sides.
So 4 plus 4 is 8, 8 plus 4 is 12, 12 plus 4 is 16, 16 plus 4 is 20, 20 plus 4 is 24. And now we're in the tens place.
2 plus 2 is 4 plus 2 is 6 plus 2 is 8 plus 2 is 10 plus 2 is 12 plus 2 is 14. So the sum of these six 24's is 144. That is the perimeter.
When we talk about corruption, there are typical types of individuals that spring to mind. There's the former Soviet megalomaniacs. Saparmurat Niyazov, he was one of them.
Welcome to this presentation on logarithm properties. Now this is going to be a very hands-on presentation. If you don't believe that one of these properties are true and you want them proved, I've made three or four videos that actually prove these properties.
Let's see. I want to change-- There you go. Let's say I say that a-- Let me start over. a to the b is equal to c.
In one, you know a and b and you're kind of getting c. That's what exponentiation does for you. And the second one, you know a and you know that when you raise it to some power you get c.
The additive exponent prop-- I don't know. I don't know the names of things. And that equals two to eight, two to the eighth.
know that three to the negative two is equal to one / nine, right? The negative just inverts it. So this is equal to negative two, right?
I would like to tell you all that you are all actually cyborgs, but not the cyborgs that you think. You're not RoboCop, and you're not Terminator, but you're cyborgs every time you look at a computer screen or use one of your cell phone devices. So what's a good definition for cyborg?
Well, traditional definition is "an organism to which exogenous components have been added for the purpose of adapting to new environments." That came from a 1960 paper on space travel, because, if you think about it, space is pretty awkward. People aren't supposed to be there.
Somebody goes to another country, says, "How fascinating these people are, how interesting their tools are, how curious their culture is." And then they write a paper, and maybe a few other anthropologists read it, and we think it's very exotic. Well, what's happening is that we've suddenly found a new species.
"Oh, wow. Now suddenly we're a new form of Homo sapiens, and look at these fascinating cultures, and look at these curious rituals that everybody's doing around this technology. They're clicking on things and staring at screens."
"I'm going to teach you about time and space in the future." And I said, "Great." And he said one day, "What's the shortest distance between two points?"
"I want to be the first person to create a wormhole, to make things accelerate faster. And I want to make a time machine." I was always sending messages to my future self using tape recorders.
But then what I realized when I went to college is that technology doesn't just get adopted because it works. It gets adopted because people use it and it's made for humans. So I started studying anthropology.
They would click on a button, and they would be connected as A to B immediately. And I thought, "Oh, wow. I found it.
And then, once you do that, you can figure out how to present your second self in a legitimate way, instead of just dealing with everything as it comes in -- and oh, I have to do this, and I have to do this, and I have to do this. And so this is very important. I'm really worried that, especially kids today, they're not going to be dealing with this down-time, that they have an instantaneous button-clicking culture, and that everything comes to them, and that they become very excited about it and very addicted to it.
(Applause)
That actually does it for Unit 6. We basically got to the main points that I wanted to tell you about. I wanted to kind of express the notion of NP completeness and give you a chance to play with that a little bit, and in the homework, we're going to look at that in a little bit more depth.
I'm a neuroscientist, and I study decision-making. I do experiments to test how different chemicals in the brain influence the choices we make. I'm here to tell you the secret to successful decision-making: a cheese sandwich.
("Official! Chocolate stops you being grumpy") Cheese? Chocolate?
Neuro drinks, a line of products, including Nuero Bliss here, which according to its label helps reduce stress, enhances mood, provides focused concentration, and promotes a positive outlook. I have to say, this sounds awesome. (Laughter)
They put 16 people inside a brain scanner and showed them videos of ringing iPhones. The brain scans showed activation in a part of the brain called the insula, a region they say is linked to feelings of love and compassion. So they concluded that because they saw activation in the insula, this meant the subjects loved their iPhones.
Oxytocin can bias people to favor their own group at the expense of other groups. And in some cases, oxytocin can even decrease cooperation. So based on these studies, I could say oxytocin is an immoral molecule, and call myself Dr. Strangelove.
(Laughter) So we've seen neuro-flapdoodle all over the headlines. We see it in supermarkets, on book covers.
SPECT imaging is a brain-scanning technology that uses a radioactive tracer to track blood flow in the brain. For the bargain price of a few thousand dollars, there are clinics in the U.S. that will give you one of these SPECT scans and use the image to help diagnose your problems. These scans, the clinics say, can help prevent Alzheimer's disease, solve weight and addiction issues, overcome marital conflicts, and treat, of course, a variety of mental illnesses ranging from depression to anxiety to ADHD.
(Applause)
Use the associative law of multiplication to write-- and here they have 12 times 3 in parentheses, and then they want us to multiply that times 10-- in a different way. Simplify both expressions to show they have identical results. So the way that they wrote it is-- let me just rewrite it.
So 3 times 10 is 30, and we still want to multiply the 12 times that. Now, what's 12 times 30? And we've seen this several times before.

A Visit from Saint Nicholos by Clement Clarke Moore Twas the night before Christmas, when all through the house Not a creature was stirring, not even a mouse;
"Now, Dasher! now, Dancer! now, Prancer and Vixen! On! Comet, on!
"Merry Christmas to all, and to all a good night!"
This UMC-750 is connected to air and power and is operational However, the machine must be leveled and checked for proper geometric alignment before it will provide optimal performance and accuracy We will rough-level the machine side-to-side and front-to-back
Attach leveling tool T-2192 to the spindle housing with the precision level parallel to the X-axis Visually verify that the edge of the level lines up with the T-slots First, we will level the machine side-to-side
Rotate the leveling tool so the precision level is parallel to the Y-axis We will now adjust the level front-to-back Once again, check that the level tool edge lines up visually with a T-slot edge
Leave the leveling tool parallel to Y-axis and move to one end of X-axis travel with Y-axis in the middle of travel
Jog X-axis from end-to-end, stopping in the middle, to check X-axis roll As you reach the end of X-axis travel, note whether the front, or back side of the machine is lower on that end Raise the lower side until the bubble reads zero
After leveling the machine, our first alignment task is to check that the B-axis is parallel to the Y-axis up and down in the Y/Z plane, and side-to-side in the X/Y plane We will use the middle leveling screws to raise the middle of the machine to bring the B and Y-axes parallel After an additional reading, we will tilt the front trunnion support to the left or right using the front leveling screws, rotating opposite each other, to align the B and Y-axes side-to-side
Now, note the B-axis position, in our case it is B0.003
Handle jogging B-axis parallel to the X-axis will serve us temporarily until the B-axis to Y-axis parallelism has been achieved Later we will check and adjust the B-axis home position
Raise the Z-axis up and command the C-axis to C90 Now we will check the parallelism of the table surface to Y-axis in the up and down direction Starting at the back of the table, zero your indicator on the table face
Sweep with Y-axis from the back to the front over twenty inches (20" or 500mm) Record the indicator reading, you find; at the front edge of the table, noting both magnitude and direction. This measurement will show us the position of the table, relative to the Y-axis in the up and down direction
With our adjustment made, we sweep back to front again with the indicator set to zero at the back edge and noting our reading at the front edge. Continue to adjust the middle screws up or down as necessary until the indicator reads zero at each end of the 20" (500 mm) sweep. until the indicator reads zero over the twenty inch (20" or 500mm) sweep Now we will check the parallelism of the table surface to Y-axis in the side-to-side direction
Raise the Z-axis out of the way and recall that, in our case, we adjusted the B-axis position to B0.003 Now we will rotate to B90.003 degrees Move the axes to bring the indicator once again to the back edge of the table
The B-axis has been aligned to both the Y/Z and X/Y planes But the B-axis and C-axis home positions still need to be verified
The B-axis home position locates the table face parallel to the X/Y plane and the C-axis home position locates the table T-slots parallel to the X-axis
Starting with C-axis home, zero return the C-axis and bring your indicator against one of the T-slot walls Sweep the table over a distance of twenty inches (20" or 500mm) along the T-slot wall With zero set at the starting point, take a reading at the end of the 20" sweep
The specification for the B-axis home position is two thousandths (0.002", 0.050mm) over 20" (500 mm). If either the B-axis or C-axis home position readings exceed their limit, then the machine leveling process will need to be repeated.
Small errors in the leveling sequence can negatively influence the B and C home positions In the unlikely event that you verified the level is correct but the B or C home positions are still out of specification a slight adjustment up or down can be made to the left or right front screws to change the B and C home positions a small amount Re-check both home positions once you have made any adjustments
Move the spindle head down to the middle of Z-axis travel Attach the magnetic base to the spindle nose Position the test indicator to measure a ten inch (10" or 250mm) diameter circle at the center of the table
"Total Indicator Reading" for all four positions should not exceed five ten-thousandths (0.0005" or 0.012mm) On a number line, our "Total Indicator Reading" is three ten-thousandths (0.0003" or 0.0076mm) TlR which puts our spindle sweep measurement in specification The spindle sweep values are also affected by the precision of the leveling sequence
Parameters 1306 and 1307 tell the machine where the center of rotation of the table is compared to the X and Y-axes
Parameter 1308 tells the machine where the B-axis of Rotation lies, compared to the Z home position You can use the WlPS probing system, along with "Visual Quick Code" to check these parameters which can then be reset, if necessary Before starting this procedure, ensure the probing system on the machine has been calibrated

With the "Finish MRZP Set" program run and parameters 1306 through 1308 checked and set as necessary the "Rotary Zero Point Offsets" have now been properly set and the machine is ready to run xxxxxxxxxxxxxxxxxxxxxxxxxxx
So 3 times x literally means-- so let me write it over here.
So we have 3 times x. So we literally have an x plus an x plus an x. That right there is a 3x.
Now, let me draw 17 objects here. So 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17. Now, these two things are equal, so anything you do to this side, you have to do to that side.
It's a different shade of green. You are just left with the 3x. The 5 and the negative 5 canceled out.
So it's 3x is going to be-- let me write the equality sign right under it-- is equal to-- or you could either just do it mathematically. Say, OK, 17 minus 5. 17 minus 5 is 12.
1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12. That's what's subtraction is. It's just taking away five things.
7x minus 2 is equal to-- I'll make the numbers not work out nice and clean-- is equal to negative 10.
Now, this all of a sudden becomes a lot more-- you know, we have a negative sign. We have a negative over here, but we're going to do the exact same thing. The first thing we want to do if we want to get the left-hand side simplified to just 7x is we want to get rid of this negative 2.
Negative 10 is out here.
Negative 10, negative 9, negative 8, negative 7. There's a bunch of numbers here. You know, dot, dot, dot.
I don't have space to draw them all, but we're starting at negative 10, and we're adding 2 to it, so we're moving in the positive direction on the number lines. So we're going 1, 2. So it's negative 8.
Don't say, OK, 10 plus 2 is 12, so negative 10 plus 2 is negative 12. No!
Negative 10 minus 2 would be negative 12 because you'd be going more negative. Here, we have a negative number, but we're going to the right. We're going in the positive direction, so this is negative 8.
And we are left with just an x is equal to negative 8 divided by 8. We could work it out. It'll be some type of a decimal, if you were to use a calculator, or you could just leave it in fraction form.
Negative 8 divided by 7 is negative 8/7.
Negative 8/7, or if you want to write it as a mixed number, x is equal to 7 goes into 8 one time and has a remainder of 1, so it's negative 1 and 1/7.
Either one would be acceptable.
I have one last -- I was going to say, trig property. One last logarithm property to show you. So let me pick a suitably festive color for this last property.
Oh I can't keep undoing. Anyway, so let me write down here with more space. Because I'm going to do something fancy.
So I've just told you the difference between revenue streams and pricing models, but let's take a look at an example. So imagine I have 15 sales reps and they cover 27 cities in the United States, and they are traveling all the time and they work for me.
"Write a mathematical expression which corresponds to x time y minus a times b times c."

I have magically deduced that you're answer is 3--tada. All right, now I'll show you how I did it. I will not leave you in suspense for very long.
Good morning. im a nerd Actually I don't know what time it is for you, it's morning for me. Welcome to the presentation on slope and y-intercept.
It just brings the line down as we lower the y-intercept. And let's see I think the slope needs to be higher, because those two points, the line that goes through them is definitely steeper. I apologize for this thing acting up like.
Almost there, I think. There you go! So the equation of this line is seven / fourx.
There we go. The equation of this line is seven / eightx plus thirteen / four. Let's see if what I said about slope is right if we move.
The y-intercept is going to be like seven and something. seven and change. So first of all let's get this slope down. Oh boy.
No, it still seems like my slope-- see the y-intercept, I'm raising the line. Oh good, I got it exactly right.
Social networks have been around as long as there've been people forming communities but the modern study of social networks is different because it's now possible to put together social networks that include data on millions of people. Now that's more than any one individual could possibly hope to understand in detail. Unit four explores the notion of statistics, numbers that summarize complex structures like social networks.
Welcome to the presentation on level 4 subtraction. Let's get started with some problems. First problem I have here is 33,220 minus 399.
So for simplicity let's just say we're borrowing a 1. So you borrow a 1 from this 2 and this 10 will become a,the 0 sorry, will become a 10. And since we borrowed that 1, this 2 will become a 1.
1 is smaller than 9, so we have to borrow again. So we borrow 1 from this 2 now. So this 2 now becomes 1.
11 is larger than a 9.
1 is not larger than 3, so we have to borrow again. This is a good problem. Maybe I should've warmed you all up a little bit more.
I think we're done now. 10 is larger than 9, 11 is larger than 9, 11 is larger than 3, 2 is larger than nothing, 3 is larger than nothing. So now we're ready to subtract.
This is the easy part. 10 minus 9 is 1.
11 minus 9 is 2.
11 minus 3 is 8.
2 minus nothing is 2.
3 minus nothing is 3. So we get 32,821. The only thing that makes this harder than just normal subtraction is that you have to know how to do the borrowing.
13 is now larger than 8, but 2 is now smaller than 7. So we have to borrow again. This 2 becomes a 12.
13 is larger than 8, 12 is larger than 7, 5 is the same as 5, so you can actually do the subtraction. Because 5 minus 5 is 0. As long as the top number's not smaller than the number below it.
13 minus 8 is 5.
12 minus 7 is 5. 5 minus 5 is 0.
5 minus nothing is 5. Bring down the 2.
So the answer is 25,055. So let's do a problem now that I think will confuse you a little bit more because the borrowing isn't as easy. You have to actually borrow from a couple places.
So the same drill. So this 2 is less than 5, so we have to borrow. So this 2 will become a 12.
And now let's check our numbers again.
12 is larger than 5, nine is larger than 5, 9 is larger than 1 6 is larger than nothing, and 3 is larger than nothing, so we're ready to subtract.
12 minus 5 is 7.
9 minus 5 is 4.
9 minus 1 is 8.
6 minus nothing is 6.
3 minus nothing is 3. So there, we're done. The answer is 36,847.
Turn that into an 11. But you can't borrow from the 0, so you're going to have to borrow from this entire 20. Well, what's 20 minus 1?
This becomes a 19. so,lets check again 11 is greater than 2. Check. 9 is greater than 0.
Uh-oh. 1 is not greater than 5. So we have to borrow again.
11 is greater than 2, 9 is greater than 0, 11 is greater than 5 2 is obviously greater than nothing below it. So we're ready to subtract.
11 minus 2 is 9.
9 minus 0 is 9.
11 minus 5 is 6.
And 2 minus nothing is 2. So 3,201 minus 502 is equal to 2,699. I think you're now ready to try some of the level 4 subtraction problems.
I've told you multiple times that the derivative of a curve at a point is the slope of the tangent line, but our friend [? Akosh ?] sent me a problem where it actually wants you to find the equation of the tangent line. And I realize, I've never actually done that.
1 times e to the 1. So it equals e. So we're saying at the point, at the point 1 comma e, so at the point 1 comma 2.71, whatever, whatever.
If you did, you should thank [? Akosh ?] for being unusually persistent, and having me do this problem. See you in the next video.
Now we have four questions about bipartite graphs. The first question asked, what is the minimum number of edges needed to make B have a single reachable component consisting of all the nodes where B is a five by three bipartite graph. We know that trees are connected and that they have n-1 edges.
By this reasoning, we can see that it would take at least seven edges needed to make B have a single reachable component consisting of all the nodes.
Mercy - Compassion
Today our satsang topic is Mercy (daya) and compassion (karuna)
Generally speaking everyone thinks that daya and karuna are the same thing There doesn't seem like there is any difference between the two Daya and karuna
There is that much of a difference [between the two] The amount of difference there exists between knowledge (gnan) and ignorance (agnan) that is the amount of difference between daya and karuna Daya occurs where there is ignorance [of the Self] and after gnan there is karuna
And that is correct as well daya is said to be the root of religion (dharma) it is considered to be the root of religion (dharma) it is not considered to be the root of spiritualism (adhyatma) it is not considered to be the root to the path of moksha it is not considered to be the root to attaining the Soul It does help one start towards [the path of] religion then by following this, after a long period of time once the Self is attained after that karuna [starts to flow]..... so, the Self is not attainable through daya alone [the route] to attain the Self is a whole different story Of the infinite virtues, this [daya] is just one virtue that is [beneficial]... for one to progress in religion, for one to become spiritually ready, of all these right worldly interactions daya actually falls under this category of right worldly interactions a lot more [virtues] are needed along with that but daya is one of the big things [needed]
Why? Because they don't have ahamkar daya will only last if it is on the basement of ahamkar if there is no ahamkar then there is no daya there then one cannot maintain daya then in that case, there will only be karuna where is the difference between the two [daya and karuna]?
Daya is considered to be an attribute with duality (dwandva guna) An attribute with duality and karuna does not have duality within it What is an attribute with duality (dwandva guna)?
Where there is daya there is mercilessness for sure that is what is said
How?
As an example Wherever daya exists
there is ahamkar there One is not able to see [bear] the suffering (dukh) of others One goes into suffering due to the suffering of others
However, the tirthankars don't have ahamkar within They don't become pained due to others" suffering A person with daya will always be helping others
Whereas the Gnanis, the Atma Gnanis, the Tirthankars don't feel daya They don't even feel dukh either They feel karuna
They try to save one, as a result they do [the opposite] with the other one
This is true for people with daya Whilst the Gnani's don't have daya Dada said,
For both [animals] the inner intent is that of karuna now how can one have karuna for the mouse? And now how can one also have karuna for the cat? What must be the internal state of the Gnani?
They [Gnanis] can see for both [animals] They can see it for the cat and they can see it for the mouse as well They see
So they [Gnanis] will have karuna for her "That what is this poor thing doing she has no idea what the result of this [action] will be" and on the other side they [Gnanis] have karuna for the mouse "That this poor thing, has got this hisaab to suffer right now, although as a result, he [the mouse] is progressing to a higher development
but he has this kind of a hisaab to die in this way" and in this manner they feel karuna [for the two] So, mercy and mercilessness doesn't arise it is the same for both Gnani's do not do any interference - reactions to interferences
They constantly have karuna
They have karuna towards all the living beings of this world Besides that, they have nothing else, They don't want anything from anybody
When you try to explain this, still one doesn't understand common people have a lot of inner intent to save, and that [inner intent] should be there because they are in the worldly life and they are with ahamkar therefore this is a positive ahamkar we are not saying that it [the ahamkar] is wrong but for those who want to attain the Self and go to Moksha they will have to become free of ahamkar, the direction they have chosen is different their destination is different this discussion is for them it is not for the common person for the common people, doing this and having daya is correct for them if that wasn't there, then they would walk in the wrong direction because the Self has not been attained and the ahamkar hasn't left if it [ahamkar] doesn't fall into saving then it [ahamkar] will fall into hurting one or the other will be there in duality
do you understand? this is a very minute point the demarcation is extremely minute it is an extremely minute demarcation
between daya and karuna Even in your business this verily happens... The opposite party [antagonist]
And then it will verily affect you inside The same [event] will be visible within
It doesn't go out of one's chit The photo gets snapped there
Uneasiness occurs over there You can't bear the other person's dukh And you feel inner suffering inside
You'll see the water shoals on the island side... while the deep soundings run to the mainland. Have any of you seen the captain today? - No.
Smile, Ivan. I was trying to make him understand there'd been a shipwreck in the channel. But how appalling!
Death is for others, not for ourselves. That is how most of my other guests have felt. Your other guests?
I'm afraid we have finished dinner. But I have ordered something for you. Thanks.
He's had our two sailors so busy... chasing around the woods after flora and fauna... that we haven't seen them for three days. But what do you hunt here? I'll tell you.
He was a very rich man... with a quarter of a million acres in the Crimea, and an ardent sportsman. When I was only still up high he gave me my first gun. - Good for him.
- I see. Oh, his hunting dogs. Keep your voice low and listen.
You and I, we are hunters. So that's your most dangerous game. Yes.
Let's get going. It seems as though we've come miles. Yeah, but three hours doesn't take you far in this jungle.
Tyler Dewar: The way I feel right now is that all of the other speakers have said exactly what I wanted to say.
(Laughter) And it seems that the only thing left for me to say is to thank you all for your kindness.
TD: But maybe in the spirit of appreciating the kindness of you all, I could share with you a little story about myself.
TD: From the time I was very young, onward, I was given a lot of different responsibilities, and it always seemed to me, when I was young, that everything was laid out before me.
TD: But before that kind of formal lifestyle happened for me, I was living in eastern Tibet with my family.
(Laughter)
But it didn't turn out to be so fun and entertaining, as I thought it would have been.
TD: Nevertheless, I felt that, even though I've been separated from my loved ones -- and, of course, now I'm even further away. When I was 14, I escaped from Tibet and became even further removed from my mother and father, my relatives, my friends and my homeland.
TD: And I still do get to keep in touch with my mother and father, albeit infrequently. I talk to my mother once in a blue moon on the telephone.
TD: So those were just a few remarks about my personal background. And in terms of other things that I wanted to share with you, in terms of ideas,
So, even though I'm somewhat happy about the wonderful developments that are happening in the world, still, I feel a sense of impediment, when it comes to the ability that we have to connect with each other on a heart-to-heart, or a mind-to-mind, level.
TC: My relationship to this concept of heart-to-heart connection, or mind-to-mind connection, is an interesting one, because, as a spiritual leader, I'm always attempting to open my heart to others and offer myself up for heart-to-heart and mind-to-mind connections in a genuine way with other people, but at the same time, I've always been advised that I need to emphasize intelligence over the heart-to-heart connections, because, being someone in a position like mine, if I don't rely primarily on intelligence, then something dangerous may happen to me.
But I had a really striking experience once, when a group from Afghanistan came to visit me, and we had a really interesting conversation.
So we ended up talking about the Bamiyan Buddhas, which, as you know, were destroyed some years ago in Afghanistan.
So, we were talking about the differences between the traditions and what many people perceived as the tragedy of the destruction of the Bamiyan Buddhas, but I offered the suggestion that perhaps we could look at this in a positive way. What we saw in the destruction of the Bamiyan Buddhas
was the depletion of matter, some solid substance falling down and disintegrating. Maybe we could look at that to be more similar to the falling of the Berlin Wall, where a divide that had kept two types of people apart had collapsed and opened up a door for further communication. So I think that, in this way, it's always possible for us to derive something positive that can help us understand one another better.
So, with regard to the development that we've been talking about here at this conference,
TD: Of course, I rejoice in the development and the growth and the rise of the noble land of India, the great country of India, but at the same time, I think, as some of us have acknowledged, we need to be aware that some aspects of this rise are coming at the cost of the very ground on which we stand. So, as we are climbing the tree, some of the things that we're doing in order to climb the tree are actually undermining the tree's very root.
So I think the way forward for the world -- one that will bring the path of outer development in harmony with the real root of happiness -- is that we allow the information that we have to really make a change in our heart.
So I think that sincere motivation is very important for our future well-being, or deep sense of well-being as humans, and I think that means sinking in to whatever it is you're doing now.
So, since we've been here this week, we've taken millions of breaths, collectively, and perhaps we haven't witnessed any course changes happening in our lives, but we often miss the very subtle changes.
So, every one of you who has come here is so talented, and you have so much to offer to the world,
His Holiness the Karmapa: Tomorrow is my Talk.
Lakshmi has worked incredibly hard, even in inviting me,
And so Lakshmi had to put up with me through all of that, but I very much appreciate the opportunity she's given me to be here. And to you, everyone, thank you very much.
(Applause) HH: Thank you very much.
(Applause)
A lot of people, including myself, have found the study of World War I to be a little bit confusing sometimes. And I think the reason is, the world was very different, leading up to World War I, than it is today.
The other thing that you might notice is this huge state called "Austria-Hungary" - often called the "Austro-Hungarian Empire." And people say, "Well, you know, I'm familiar with some of these nations that have the words 'Austria' and 'Hungary' in them.
It really was trying to cobble together all of these folks that spoke all [of these] different [languages] - [and that consisted of] all [of these] different types of [ethnicity].
This is kind of a zoom-in of the Austro-Hungarian empire leading into World War I. And the Austro-Hungarian Empire is probably the most important empire to focus on if we're trying to understand how World War I started.
And you see probably the most dominant empire here is the British Empire. That's [the area in] pink [here]. That's the United Kingdom.
In particular, you have Great Britain - or or the United Kingdom - that obviously had a vast empire. "The sun never sets on the British Empire." And it wasn't ever setting on this empire that we just saw here.
John: Hi, I'm John Green. This is Crash Course World History and today we're going to talk about World War Il.
(chair rolling) An open letter to Canada. But first, let's see what's in the secret compartment today.
So the last thing I promised I would tell you about is inserting elements into a heap. And that turns out not to be all that hard, but it does involve some coding that we haven't done yet. The idea is that the new element that we're going to insert we stick at the sort of bottom right corner of the heap.
By running through the list of the N elements that we want the TopK of, and meanwhile we keep a heap of size K off to the side, and so we're trying to the largest K, in this case. So each new element that we encounter we ask, is this element bigger than the smallest value that we've kept so far? So does it deserve to be in the TopK so far?
Order the 4 phases of using customer development when building a company.
So, let's build up to the answer in steps. We know that if n=1, it just returns a single node.
If n=2, it's going to recursively generate a single node for G1, a single node for G2, then randomly choose nodes from those sets, which in this case are just the only nodes that are there, so it'll choose them, and then it connects them up. So, that's what n=2 looks like.
For n=4, we have two n=2, right?
G1 and G2 are both going to be an n=2 graph. Let me draw those. Then, it's going to randomly choose one of the nodes and one of the nodes and connect them up.
Convert 37 centimeters to meters. Let me write this over. 37, and I'll write centi in a different color to emphasize the prefix.
There are other companies who want to go for revenue first— typically, hardware companies, but not always. Sometimes on the web as well. The questions to ask are how long will it take to start doubling my revenue every month.
Today, we're going to be talking about distribution channels. How does your product get from your company to your customer? You're all familiar with the business model canvas.
Estimate the solution to 582,205 plus 610,859, rounding these two numbers to the nearest thousand. So we going to round each of these numbers to the nearest thousand and then add them, and that'll give us an estimate to this solution. So let's do each of these numbers.
582,000 when we rounded it down to the nearest thousand. Now, we have 610,859. Same drill.
Less than 5, round down. It is 5 or greater.
8 is greater than 5. Or it could even be 5 and we'd still around up, so we're going to round up in this situation. We're going to round up, so we end up with 600, and instead of 610,000, we're rounding up to 611,000.
0 plus 0 is 0.
0 plus 0 is 0.
0 plus 0 is 0.
2 plus 1 is 3.
8 plus 1 is 9.
5 plus 6 is 11. If there were more places here, we would carry the 1 in the tens place. But there isn't, so you can just write an 11 here.
Welcome back. So where we left off in the last video, I'd shown you this thing called the geometric series. And, you know, we could have some base a.
And that equals-- well, that's just going to be a times this exact sum, right? And that's the same a as this a, right? That a is the same as this a.
That is just a to the zero, plus a to the 1, plus a squared, plus up, up, up, up. All the way to plus a to the n, right? So let me ask you a question.
I think I can safely erase all of this, really. Well, I don't want to erase that much. I want to erase this stuff.
That's good enough. OK. So I have just-- dividing both sides of this equation by a minus 1, I get s is equal to a to the n plus 1 minus 1 over a minus 1.
1/2 to the zero, plus 1/2, plus-- what's 1/2 squared? Plus 1/4, plus 1/8, plus 1/16. So as you see, each term is getting a lot, lot smaller.
1/2 to the n is the same thing as 1 over 2 to the n. And if we look at the formula we figured out, we would say, well, that is just equal to 1/2 to the n plus 1, minus 1, over 1/2 minus one. And that would be our answer.
What's 1/2 to the infinity power? Well, that's zero. That's an unbelievably small number.
I bring to you a message from tens of thousands of people -- in the villages, in the slums, in the hinterland of the country -- who have solved problems through their own genius, without any outside help. When our home minister announces a few weeks ago a war on one third of India, about 200 districts that he mentioned were ungovernable, he missed the point. The point that we have been stressing for the last 21 years, the point that people may be economically poor, but they're not poor in the mind.
These are the three guiding principles of the Honey Bee Network: that whenever we learn something from people it must be shared with them in their language. They must not remain anonymous. And I must tell you that after 20 years,
(Audience Member: Rajasthan.) Anil Gupta:

"God, please cure him. And if you cure him, I will get my wall painted." And this is what he got painted.
"What is a scalable model?" -- as if the need of a community, which is only located in a space and time and has those needs only located in those places, has no legitimate right to get them for free because it's not part of a larger scale. So either you sub-optimize your needs to a larger scale or else you remain out.
I had to meet my love.
My desperation made me an innovator.
Even love needs help from technology.
Innovation is the light of my wife, Noor. New inventions are the passion of my life. My technology.
It's not that a coconut fell on my head, and I came upon this idea.
With no money to fund my studies, I scaled new heights. Now, they call me the local Spiderman.
My technology. (Applause) AG:
"How do we elongate the life of this girl of our village?" They were not related to her, but they tried to find out, "How can we use ... "
"Give me a place to stand, and I will move the world." I will just tell you that we are also doing a competition among children for creativity, a whole range of things. We have sold things all over the world, from Ethiopia to Turkey to U.S. to wherever.
A local hospital recently conducted a blood drive where they collected a total of 80 pints of blood from donors. The hospital was hoping to collect a total of 8 gallons of blood from the drive. Did they meet their goal?
But when problems get a little bit more complicated, it is nice to make sure that the units cancel out in this way, so that you know, OK, 1 quart is 2 pints. Pints in the denominator, pints in the numerator, cancel them out, and I'm just left with quarts, and 80 times 1/2, which is 40. So we have 40 quarts now, and now we can convert this to gallons.
40 times 1/4 is the exact same thing as 40 divided by 4, which makes sense. We're going to a larger unit. So 40 times 1/4 is 10, and the units left are gallons.
So did they meet their goal? Yes, they met their goal! How much more or less than their goal did the hospital collect?
So, what are we even talk...mean, when we say Order of Operations?
So let me give you an example. The whole point, is so we have one way to interpret a mathematical statment. So let's say I have the mathematical statement:
So, that's one way you would interpret it if we didn't agree on an order of operations - maybe it's a natural way - you just go left-to-right. Another way you could interpret it -- you say "oh, I like to do multiplication before I do addition" so you might interpret it as - I'll try to color code it - 7+ ... and you do the 3x5 first 7 + 3x5 which would be 7+ 3x5 is 15 ... and 7+15 is 22.
This way, we did the multiplication first, then the addition. We get 2 different answers. That's just not cool in mathematics.
So this is just completely unacceptable, and that's why we have to have an agreed upon Order of Operations. an agreed upon way to interpret this statement. So, the agreed upon order of operations is to do parentheses first. -- let me write it over here --
If you don't know what exponents are, don't worry about it right now. In this video we're not going to have exponents in our examples. So you don't really have to worry about it for this video.
Then you do multiplication and division next. they kind of have the same level of priority. And then finally you do addition and subtraction. So, what is this order of operations?
Let me label it - this right here is, that is the agreed upon order of operations and if we follow these order of operations we should always get to the same answer for a given statement. So what does this tell us? What is the best way to interpret this up here?
Then it simplifies to that right there. Remember multiplication and division, they are at the exact same level - so we're going to do it left-to-right. You xould also express this as multiplying by one-half and then it wouldn't matter the order.
So 40 divided by 2 is 20. We're going to have that minus sign. -5 times 6 is 30.

By the end of this year, there'll be nearly a billion people on this planet that actively use social networking sites. The one thing that all of them have in common is that they're going to die. While that might be a somewhat morbid thought,
There are 200 million Tweets being posted every day. And the average Facebook user is creating 90 pieces of content each month. So when you think about your parents or your grandparents, at best they may have created some photos or home videos, or a diary that lives in a box somewhere.

What's the most common marketing mistake? Believing that our product is special when it's really just a yawner. When we delude ourselves, we make mistakes like this.
Bud light goes down smooth like this guy here.
Where other beers, go down like this guy." So if your product isn't that dazzling, you must step boldly into the world of distraction. Your ad must be so funny, or so dazzling that your audience can't turn away. Then, your product pitch can come along for the ride.

I'm a storyteller. And I would like to tell you a few personal stories about what I like to call "the danger of the single story." I grew up on a university campus in eastern Nigeria.
All my characters were white and blue-eyed, they played in the snow, they ate apples, (Laughter) and they talked a lot about the weather, how lovely it was that the sun had come out.
(Laughter) Now, this despite the fact that I lived in Nigeria. I had never been outside Nigeria.
(Laughter) And for many years afterwards, I would have a desperate desire to taste ginger beer.
And when I didn't finish my dinner, my mother would say, "Finish your food! Don't you know?
(Laughter) She assumed that I did not know how to use a stove. What struck me was this:
Although I still get quite irritable when Africa is referred to as a country, the most recent example being my otherwise wonderful flight from Lagos two days ago, in which there was an announcement on the Virgin flight about the charity work in "India, Africa and other countries."
(Laughter) So, after I had spent some years in the U.S. as an African, I began to understand my roommate's response to me.
After referring to the black Africans as "beasts who have no houses," he writes, "They are also people without heads, having their mouth and eyes in their breasts." Now, I've laughed every time I've read this. And one must admire the imagination of John Lok.
A tradition of Sub-Saharan Africa as a place of negatives, of difference, of darkness, of people who, in the words of the wonderful poet Rudyard Kipling, are "half devil, half child." And so, I began to realize that my American roommate must have throughout her life seen and heard different versions of this single story, as had a professor, who once told me that my novel was not "authentically African." Now, I was quite willing to contend that there were a number of things wrong with the novel, that it had failed in a number of places, but I had not quite imagined that it had failed at achieving something called African authenticity.
It's a noun that loosely translates to "to be greater than another." Like our economic and political worlds, stories too are defined by the principle of nkali: How they are told, who tells them, when they're told, how many stories are told, are really dependent on power.
-- and that it was such a shame that young Americans were serial murderers.
(Laughter) (Applause) Now, obviously I said this in a fit of mild irritation.
(Laughter) But it would never have occurred to me to think that just because I had read a novel in which a character was a serial killer that he was somehow representative of all Americans. This is not because I am a better person than that student, but because of America's cultural and economic power,
(Laughter) But the truth is that I had a very happy childhood, full of laughter and love, in a very close-knit family. But I also had grandfathers who died in refugee camps.
What the Nigerian writer Chinua Achebe calls "a balance of stories." What if my roommate knew about my Nigerian publisher, Muhtar Bakare, a remarkable man who left his job in a bank to follow his dream and start a publishing house?
I went to a TV station in Lagos to do an interview, and a woman who worked there as a messenger came up to me and said, "I really liked your novel. I didn't like the ending.
(Applause)
Let's take a look at a customer acquisition process that reaches 100 people a day and activates 10%. How many customers will you have after two days? And how many will you have after a week?
Well, welcome back! I'm going to show you the last two logarithm properties now. So this one-- and I always found this one to be in some ways the most obvious one.

MENTOR AND STUDENTS: [Hearty laughter.] MENTOR:
Now that we have our tile sets parsed, we need a way to find the image and coordinate position of a specific tile in a tile set from our data array. Now to do this, we're going to have to create a new function called getTilePacket. That takes the index value we want from the data array of a layer, and determines an object like you see here.
Welcome to this "VMC Leveling" video This VF-2SS is connected to air and power and is operational however, the machine is not at the proper height or level to provide optimal performance and accuracy There are three steps to the leveling process
Larger machines with outrigger supports require additional steps during the leveling process This information can be found in the Haas machine Installation manual
To clear the coolant tank lift the Base Casting three and a half (3 ½") inches off the ground by adjusting the four corner leveling screws to the same height On base castings with 6 or 8 leveling screws the middle screws should not be touching the pads during the leveling procedure
Move the X and Y axes until the table is centered Clean the table surface and the leveling tool Make sure the calibration of your level is correct before starting
At the column side, look to see which rear corner of the machine if any, is lowest as shown by the leveling tool In this video, the leveling tool is angled down at the right rear corner of the machine as we get to full axis travel at the column This shows the right rear corner of the machine is low
With the leveling tool still parallel to the X-axis, re-measure for twist Start at the operator side move to the middle of Y-axis travel and then to the Column side Adjust the middle screws to remove any twist caused when the screws were tightened
Place the Leveling Tool in the center of the Mill Table with the precision vial parallel to the Y-axis Look at the bubble position at the operator side at the middle of Y-axis travel and at the Column side If the measurement shows there is bow in the base casting in either the up or down direction use the middle screws to make adjustments
Moving the Z-axis in "tenths" mode, bring the Test Indicator down to contact the mill table and zero the test indicator Take a measurement every 90 degrees of rotation This provides two values along the Y-axis and along the X-axis
Lock the leveling screws in place Tighten the locking nuts while holding the leveling screws so they don't rotate The customer's machine is now at the proper height and level and is free of any twist or bow in the base casting
Let's go over now how we can actually solve the top K problem using this idea of partitioning. Now, remember what we're given her is the list L and some number K and what we're interested in are the top K elements of L, and for the sake of simplicity in this example by top--I mean the smallest, the one that have the smallest values. You can always put things around, turn the right greater ends into less ends and so forth and everything will be fixed, but for now, let's just imagine that we're interested in the smallest element-- the smallest K elements if the lists were sorted.
In this video, I want to talk a little bit about Newton's first law of motion, And this is a translation from Newton's principia from Latin to English. So, the first law:
Lens problems are actually quite common throughout all camera brands. Usually it's cause by sand or grit interfering with the lens extension mechanism. Or the camera's been dropped with the lens extended.
These repair methods are listed in the order of risk of damaging your camera. Thus make sure you try them in the listed order.
And remember, these fixes (especially #6 and 7) should only be considered for a camera that's out of warranty, who's cost of repair would be excessive, and would otherwise be considered for disposal if unrepaired:
#1: Remove the batteries from the camera, wait a few minutes.
Put a fresh set of batteries back in (preferably rechargeable NiMH 2500mah or better) and turn the camera on.
If using rechargeables, and they're more than a year old, consider purchasing new rechargeable batteries as they may not be providing sufficient power to startup the camera.
#1a: If new batteries didn't work, try pressing and holding the Menu, Function, Function Set, or OK button while turning the camera on.
This along with Fix #1c and #2 sometimes work for lens errors that occur from batteries wearing down while the lens was extended. For those of you who can still access your camera's menus with this error, try finding and selecting the "factory reset" option to set your camera back to its original factory condition.
On some Canon cameras, this requires holding the menu button down with the camera powered on for up to 10 seconds. However note that a lens error might sometimes override the reset option, and thus the option might not appear.
#2: If the camera's batteries ran down completely while its lens was still open, the camera may show a lens error or not start properly when new batteries are installed. Remove the memory card and keep it removed, then install the new batteries.
Error E30 (for older Canon's) means that you don't have a memory card installed, so turn it off, slip in the SD card and turn it on one last time
#3:
Insert the cameras Audio/Video (AV) cable, and turn the camera on. Inserting this cable ensures that the camera's LCD screen remains off during the start process. Thus extra battery power is available to the camera's lens motor during startup.
If the AV cable doesn't fix the lens error by itself, consider keeping this cable installed while trying fixes 4, 5, and 7 as a means to provide extra power to help to these fixes.
But note that I DON'T recommend keeping the cable installed during Fix 6 as you may damage the AV port while tapping the camera.
Reinsert the cable only AFTER tapping the camera.
#4: Place the camera flat on its back on a table, pointed at the ceiling. Press and hold the shutter button down, and at the same time press the power-on button.
#5: Blow compressed air in the gaps around the lens barrels with the idea of blowing out any sand or grit that may be in there jamming the lens.
Other variations include blowing with a hair dryer in "no heat" setting, or sucking the gaps with a vacuum (careful with this one). Some people also have actually used a "Shop Vac" with this fix to help extend a retracted lens.
#5a: If you actually do notice sand particles stuck in the gaps around the lens barrel, and blowing air does not help to dislodge them, consider using a thin piece of paper or a sewing needle to help dislodge them. Pay particular care not to scratch your lens barrel with the needle.
Also, I do not recommend probing too deeply around the lens barrel with the paper (don't go more than a 1 cm or 1/2 in) .
Particularly I do not recommend probing deeply around the most outer (largest) lens barrel gap, as you may dislodge the lens barrel dust gasket that's located just inside of that gap.
Now we're entering into the realm of potentially damaging your camera in conducting the fix. There is definitely some risk in the following repair techniques, so carefully consider your options before considering conducting the following fixes. The following fixes are NOT recommended for a valuable camera.
#6: Repeatedly tap the padded/rubber usb cover on a hard surface with the intent of dislodging any particles that may be jamming the lens gears located inside the camera. Other variations include hitting a side of the camera against the palm of your hand.
#6a:
This is a variation of Fix #6, and should be tried if the lens barrels appears straight (not crooked).
In other words, try this if there's no obvious mechanical damage to the lens barrels that's causing the problem. With the lens pointed down, try "gently" tapping around the lens barrels with a small item such as a pen or pencil. The idea is to try to dislodge any sand particles that may be jamming the lens barrel stuck.
The next repair steps discussed are very extreme and have high potential for damaging your camera. However, they also have been shown to be the most effective in correcting a lens error. Again, consider the following only for a camera that you will dispose of if you can not repair it yourself.
#7a: Note that this particular fix is intended only for cameras with lens barrels that try to extend, but then stop partway, and then return to their stored position. Try grabbing and holding the smallest inner lens barrel at its furthest extended position, preventing it from returning to the camera.
#7b: You especially might consider this if the lens barrel appears obviously damaged, bent, or crooked such as from a fall. In that case, try thinking of the lens as a dislocated shoulder.
In such cases, the lens barrel guide pins have become unseated from their guide slots (see the below illustration). Your objective would be to try to reseat them by straightening the lens. Listen for a "click" to hint that they've been reseated, and immediately stop forcing the lens at this point.
More people have reported success with this method than with any of the other methods (see the polls in the right column).
Variations to #7b include gently pulling, rotating, and/or twisting the lens barrel while hitting the power button. Examine the lens barrels closely for any hint of tilt or unevenness. Again, the goal is to attempt to straighten or align the barrel if it's crooked or twisted.
Another variation includes looking for uneven gaps around the lens barrel, and then pushing on the side of the lens barrel that has the largest gap (note pushing the lens barrel all the way in is NOT recommended as it may become stuck there). Again, while doing any of the above, listen for a click that indicates that the lens barrel guide pins may have reseated in their guide slots. If you hear this click, immediately stop and try the camera.
Repeated tries of the above may be necessary. Consider repeating these steps, especially if you notice some progress in the operation of the camera.
The camera was finally repaired after three tries of fix #7b.
If you try these fixes, please post a comment on how the fixes worked for you. Your experience may help others. Note that most of the fixes listed here actually came from reader's comments on my blog site.
Life, liberty and the pursuit of happiness. We live our lives pursuing happiness "out there" as if it is a commodity. We have become slaves to our own desires and craving.
The ancient tenant "know thyself" has been replaced by a desire to experience the outer world of form. Answering the question "who am I?" is not simply a matter of describing what is on your business card. In Buddhism, you are not the content of your consciousness.
"I don't believe people are looking for the meaning of life, as much as they are looking for the experience of being alive." When the Buddha was asked, "what are you?" he said simply,
"I am awake." What does this mean, to be awake? The Buddha does not say exactly, because of the flowering of each individual life is different.
The Buddha spoke of the "middle way" as the path that leads to enlightenment.
Aristotle described the Golden Mean - the middle between two extremes, as the path of beauty. Not too much effort, but not too little either.
Yin and yang in perfect balance. Vedanta's notion of Maya or illusion, is that we do not experience the environment itself, but rather a projection of it created by thoughts. Of course your thoughts let you experience the vibratory world in a certain way, but our inner equanimity need not be contingent on external happenings.
Synesthetes can see sounds as colors or shapes or associate qualities of one sense with another.
Synesthesia refers to a synthesis or intermingling of the senses. The chakras and the senses are like a prism filtering a continuum of vibration. All things in the universe are vibrating but at different rates and frequencies.
Leo Tolstoy, author of "War and Peace", said
"everyone thinks of changing the world, but nobody thinks of changing him or herself." Darwin said the most important characteristic for the survival of the species is not strength or intelligence, but adaptability to change. One must become adept at adapting.
I was here four years ago, and I remember, at the time, that the talks weren't put online. I think they were given to TEDsters in a box, a box set of DVDs, which they put on their shelves, where they are now. (Laughter)
Don't you feel? (Laughter)
So, this whole event has been an elaborate build-up to me doing another one for you, so here it is. (Laughter)
Al Gore spoke at the TED conference I spoke at four years ago and talked about the climate crisis. And I referenced that at the end of my last talk. So I want to pick up from there because I only had 18 minutes, frankly.
You see, he's right. I mean, there is a major climate crisis, obviously, and I think if people don't believe it, they should get out more. (Laughter)
Well, I do. (Laughter)
I meet all kinds of people who don't enjoy what they do. They simply go through their lives getting on with it. They get no great pleasure from what they do.
No, it doesn't. (Laughter) It doesn't.
A friend of mine once said, "A three year-old is not half a six year-old." (Laughter) (Applause)
See, it's outrageous as a conception. The other big issue is conformity. We have built our education systems on the model of fast food.
What I want to do is to give you a broad overview of all of the wars that France was in at this time, and then talk about, in a little bit more detail, exactly what Napoleon was up to, and his role in either beginning or ending many of these wars.
So, you might remember, from 1792 to 1797, you had the war of the First Coalition.
And the players there were Prussia, Austria, and Great Britain. I'll just write "Britain" for short.
And, you might remember, it ended in the Treaty of Campo Formio, in 1797, due mainly to Napoleon's victories in Italy. This was Campo Formio there. At that time, he was in charge of the Italian Campaign; and the government of France, at that time, was the Directory -- in power, to a large degree -- because of Napoleon's ability to defend them.
They tend to be always at war with France in this period -- especially Great Britain. And instead of Prussia, you have Russia. And actually, just to help you visualize what the Austrian Empire looked like at this time, and the Prussian Empire. ...this map doesn't do it in justice.
As you can see, it is much... it encompasses much more than just the modern nation, or country, of Austria. Then you have the Russian Empire, which, you know, give or take, looks not too different than Russia today.
Here's a planar graph--a bunch of nodes and edges. I want you to figure out how many regions are in this graph and then write it in this box.
So, the first robot to talk about is called STriDER. It stands for Self-excited
Tripedal Dynamic Experimental Robot. It's a robot that has three legs, which is inspired by nature. But have you seen anything in nature, an animal that has three legs?
The problem that we had with STriDER I is it was just too heavy in the body. We had so many motors, you know, aligning the joints, and those kinds of things. So, we decided to synthesize a mechanical mechanism so we could get rid of all the motors, and with a single motor we can coordinate all the motions.
For IMPASS, we can do many, many different types of motion. For example, in this case, even though the left and right wheel is connected with a single axle rotating at the same angle of velocity. We just simply change the length of the spoke.
Cable-suspended Limbed Intelligent Matching Behavior Robot.
So, I've been talking to a lot of NASA JPL scientists -- at JPL they are famous for the Mars rovers -- and the scientists, geologists always tell me that the real interesting science, the science-rich sites, are always at the cliffs. But the current rovers cannot get there. So, inspired by that we wanted to build a robot that can climb a structured cliff environment.
Multi-Appendage Robotic System. So, it's a hexapod robot. We developed our adaptive gait planner.
Welcome to RoMeLa, the Robotics Mechanisms Laboratory at Virginia Tech. This robot is an amoeba robot. Now, we don't have enough time to go into technical details,
Robotic Air Powered Hand with Elastic Ligaments. There are a lot of really neat, very good robotic hands out there in the market. The problem is they're just too expensive, tens of thousands of dollars.
Hyper Degrees-of-freedom Robotic Articulated Serpentine. This is a robot that can climb structures. This is a HyDRAS's arm.
We actually have a fan club for the robot, DARwln:
Dynamic Anthropomorphic Robot with Intelligence. As you know, we are very interested in humanoid robot, human walking, so we decided to build a small humanoid robot. This was in 2004; at that time, this was something really, really revolutionary.
(Laughter) So, based on that success, the following year we did the proper mechanical design starting from kinematics. And thus, DARwln I was born in 2005.
DARwln also has a lot of other talents. Last year it actually conducted the Roanoke Symphony Orchestra for the holiday concert. This is the next generation robot, DARwln IV, but smarter, faster, stronger.
"I'm macho, I'm strong. I can also do some Jackie Chan-motion, martial art movements." (Laughter)
We have a fully autonomous vehicle that can drive into urban environments. We won a half a million dollars in the DARPA Urban Challenge. We also have the world's very first vehicle that can be driven by the blind.
Let's see if we can learn a thing or two about the hyperbola.
And out of all the conic sections, this is probably the one that confuses people the most, because it's not quite as easy to draw as the circle and the ellipse. You have to do a little bit more algebra. But hopefully over the course of this video you'll get pretty comfortable with that, and you'll see that hyperbolas in some way are more fun than any of the other conic sections.
I always forget notation. Approximately. This just means not exactly but approximately equal to.
So in the positive quadrant, that tells us we're going to be up here and down there. Another way to think about it, in this case, when the hyperbola is a vertical hyperbola, where it opens up and down, you notice x could be equal to 0, but y could never be equal to 0. And that makes sense, too.

So the Awesome story: It begins about 40 years ago, when my mom and my dad came to Canada. My mom left Nairobi, Kenya.
I found a girl, I settled down -- and I realize it sounds like a bad sitcom or a Cat Stevens' song -- (Laughter) but life was pretty good. Life was pretty good.
2006 was a great year. Under clear blue skies in July in the wine region of Ontario, I got married, surrounded by 150 family and friends.
2007 was a great year. I graduated from school, and I went on a road trip with two of my closest friends. Here's a picture of me and my friend, Chris, on the coast of the Pacific Ocean.
(Laughter) So you can't actually see them, but it was breathtaking, believe me.
(Laughter) 2008 and 2009 were a little tougher. I know that they were tougher for a lot of people, not just me. First of all, the news was so heavy.
2008, 2009 were heavy years for me for another reason, too. I was going through a lot of personal problems at the time. My marriage wasn't going well, and we just were growing further and further apart.
(Laughter) And slowly over time, I started putting myself in a better mood.
(Laughter) And then I got excited when it started getting tens of hits, and then I started getting excited when it started getting dozens and then hundreds and then thousands and then millions. It started getting bigger and bigger and bigger.
"You've just won the Best Blog In the World award." I was like, that sounds totally fake.
(Laughter) (Applause) Which African country do you want me to wire all my money to?
(Laughter) But it turns out, I jumped on a plane, and I ended up walking a red carpet between Sarah Silverman and Jimmy Fallon and Martha Stewart. And I went onstage to accept a Webby award for Best Blog.
(Applause) But look, I said I wanted to do three things with you today. I said I wanted to tell you the Awesome story,
The second "A" is Awareness. I love hanging out with three year-olds. I love the way that they see the world, because they're seeing the world for the first time.
These were four guys on the L.A. Rams in the 1960s you did not want to go up against. They were tough football players doing what they love, which was crushing skulls and separating shoulders on the football field. But Rosey Grier also had another passion.
And he even put out a book called "Rosey Grier's Needlepoint for Men."
(Laughter) (Applause) It's a great cover. If you notice, he's actually needlepointing his own face.
(Laughter) And so what I love about this story is that Rosey Grier is just such an authentic person, and that's what authenticity is all about. It's just about being you and being cool with that.
(Applause) When I was growing up, my dad used to love telling the story of his first day in Canada. And it's a great story, because what happened was he got off the plane at the Toronto airport, and he was welcomed by a non-profit group, which I'm sure someone in this room runs.
(Laughter) And this non-profit group had a big welcoming lunch for all the new immigrants to Canada. And my dad says he got off the plane and he went to this lunch and there was this huge spread.
"The craziest thing was, I'd never seen any of that before, except bread.
(Laughter) I didn't know what was meat, what was vegetarian. I was eating olives with pie.
(Laughter)
I just couldn't believe how many things you can get here."
(Laughter) When I was five years old, my dad used to take me grocery shopping, and he would stare in wonder at the little stickers that are on the fruits and vegetables. He would say, "Look, can you believe they have a mango here from Mexico?
"Can you believe someone climbed a tree over there, picked this thing off it, put it in a truck, drove it all the way to the docks and then sailed it all the way across the Atlantic Ocean and then put it in another truck and drove that all the way to a tiny grocery store just outside our house, so they could sell it to us for 25 cents?" And I'd say, "I don't believe that." And he's like, "I don't believe it either.
The cashiers at your grocery store, the foreman at your plant, the guy tailgating you home on the highway, the telemarketer calling you during dinner, every teacher you've ever had, everyone that's ever woken up beside you, every politician in every country, every actor in every movie, every single person in your family, everyone you love, everyone in this room and you will be dead in a hundred years. Life is so great that we only get such a short time to experience and enjoy all those tiny little moments that make it so sweet. And that moment is right now, and those moments are counting down, and those moments are always, always, always fleeting.
You will never be as young as you are right now. And that's why I believe that if you live your life with a great attitude, choosing to move forward and move on whenever life deals you a blow, living with a sense of awareness of the world around you, embracing your inner three year-old and seeing the tiny joys that make life so sweet and being authentic to yourself, being you and being cool with that,
I want to talk about the transformed media landscape, and what it means for anybody who has a message that they want to get out to anywhere in the world. And I want to illustrate that by telling a couple of stories about that transformation. I'll start here.
(Laughter) Now they might have liked to have done that here, rather than seeing these pictures go up online. But they weren't given that choice, because their own citizens beat them to the punch.
The 10th one was kittens on a treadmill, but that's the Internet for you.
(Laughter) But nine of the 10 in those first hours. And within half a day donation sites were up, and donations were pouring in from all around the world.
"How can we make best use of this media? Even though it means changing the way we've always done it." Thank you very much.
Show 109% by shading. So just as a bit of review, 109% if we were to write it out, would literally be 109 percent, which is the same thing as 109 per-- and I could write cent again, but that's getting old. Cent means 100, so it literally means 109 per hundred.
If you just shaded that in, that would be 100%. That would be 100/100, or 100 per 100, or 100%. I think you're getting the meaning of all of this.
Let's take a look at the first piece called the value proposition. The value proposition answers the question what are you building and for who? The value proposition says, "Hey, it's not about your ideal product, it's about solving a problem or a need for a customer."
Like Facebook or Twitter. Those are needs. Needs are different than problems.

When I was 10 years old, a cousin of mine took me on a tour of his medical school. And as a special treat, he took me to the pathology lab and took a real human brain out of the jar and placed it in my hands. And there it was, the seat of human consciousness, the powerhouse of the human body, sitting in my hands.
Within a period of 60 days, his vocabulary went from two to three words to 300 words. And his communication and social interaction were improved so dramatically that he was enrolled into a regular school and even became a karate super champ. Research shows that 50 percent of children, almost 50 percent of children diagnosed with autism are actually suffering from hidden brain seizures.
These are the faces of the children that I have tested with stories just like Justin. All these children came to our clinic with a diagnosis of autism, attention deficit disorder, mental retardation, language problems. Instead, our EEG scans revealed very specific problems hidden within their brains that couldn't possibly have been detected by their behavioral assessments.
(Applause)
Now that your done with the lectures, it's not the end. One of the things you might consider doing is putting together a lessons learned presentation. This summarizes everything you learned week to week either by watching the lectures or hopefully getting out of the building and talking to customers.
Take a look at steveblank.com and Alexander Osterwalder's website, businessmodelgeneration.com. I also recommend checking out startupweekend.org for other events and other courses, and we'll see you when you're a public company.
We're asked to add 4/9 and 11/12 and to write our answer as a mixed number, and then simplify and write our answer as a mixed number. So here we have two fractions we're adding together, but we have different denominators. So whenever you add fractions, the first thing you have to do is check the denominators.
27 isn't divisible by 12. 36, well, that is divisible by 12. That is 12 times 3.
9 times 4 is equal to 36. Now, you can't just multiply the denominator by 4. You also have to multiply the numerator by the same thing.
36, 12 times 3, so we're multiplying 12 by 3 to get 36. Well, if we did that to the denominator, we also have to do that to the numerator, so 11 times 3 is 33. And just like that, we've now rewritten each of the fractions so that they have the same denominator.
16 plus 33 in the numerator. And 16 plus 33 is what?
6 plus 33 would be 39 and then you have another 10, so it's 49. So it's equal to 49/36. Now, can we simplify this?
49, it's 7 squared, so it has 1, 7 and 49 as factors. This has 1-- it has a bunch of numbers, but it's not divisible by 7, so this is actually in simplest form, but this is an improper fraction. The numerator is larger than the denominator.
36 goes into 49 one time.
1 times 36 is 36, and then you subtract. 9 minus 6 is 3. 4 minus 3 is 1.
Gram is a unit of mass.
So decigram just means 1/10 of a gram. Millimeter. Meter is a unit.
An inch is a unit of length. We're all familiar with it. An ounce-- you have to be careful here-- if someone just has an ounce, that is 1/16 of a pound.
This brings us to a slightly more interesting problem called the Top K Problem. Here's the idea. Imagine we've got our list of values L, and there's n values in the list.
What do we do about computing statistics like those in an unsorted list. Well, plan A, especially for mathematical-minded people, might be to sort the list first, which as we say reduces the problem to one previously solved so that is safe. We know how to sort.
Âľ or the mean is the sum over all the elements on the list from 0 to n-1 We look up the value, we sum them all together, and then we divide by the number of values. It's just the definition of an average, and it's really straightforward to do that in Python as well.
Let's talk about how we might implement the shortestdistnode function. We give it all the distances we've calculated so far for all the nodes that we could do that for and so that's just a big pile here. There is a bunch of nodes and for each node, we have some value and a lot of these values are temporarily assigned and they may actually change later, but what we want to know is which of these we'd like to pull out the smallest value and then we'd actually like to lead it from this set so we don't have to worry about getting the same value over and over and over again
The shortestdistnode, you give it a mapping distances and it starts off with the best node undefined and best value something big from probably really want something bigger than this and for all the nodes that we have distances for If the distance for that node is better than the best we've seen so far, reassign and when you're done, just return the best node. This is really quite straightforward and what is the running time that this leads to?

Worldly Interactions without the inner hidden enemies of anger, pride, deceit and greed Jai Sat Chit Anand Today, our subject [for samayik] is
Up until the Self (atma) has not been realized all worldly interactions (vyavahar) are merely worldly interactions. Once the Self and its realm (nischay) is attained the actual vyavahar starts after that The correct [type of] vyavahar...
So, after this knowledge of the Self (Gnan) is attained, after the enlightened world view (samyaktva) is acquired, the worldly interactions that transpire, those worldly interactions (vyavahar) are called vyavahar without the inner hidden enemies of anger, pride, deceit and greed and it is called pure worldly interactions (shuddha vyavahar)
In case of mahatmas, after they have taken gnan, all their vyavahar is considered shuddha vyavahar. To remain in the pure Soul (Shuddhatma) and the 5th special directive (agna) from the moment one gets the chance to progress somewhat further in this from that moment onwards [it is considered shuddha vyavahar]
What is pure worldly interaction (shuddha vyavahar)?
The vyavahar that occurs after the Self and its realm (nischay) has been attained that is considered shuddha vyavahar. After attaining the Self (atma), the vyavahar that continues to remain, that is considered shuddha vyavahar. And until the atma is not attained the vyavahar is not considered pure (shuddha).
Worldly interactions (vyavahar)... it is on the foundation of vyavahar that nischay verily exists despite that vyavahar is a discharge (nikali) although vyavahar is nikali it is not worthy of intense contempt (tarchhod). By having intense contempt for vyavahar, it is not like nischay will become attained In fact if you have tarchhod for it [vyavahar], then nischay vanishes
In reality what is considered actual shuddha vyavahar? according to Dada in Akram, that if you are hurling abuses at someone
even then that vyavahar is called shuddha Why? In what way?
[The answer is] at that moment, what is going on within you? If it remains within you that "this Nitin (File 1) is hurling abuses
there is equanimity (sambhaav) within you And on the outside in the discharge [action] one is hurling abuses he doesn't have the desire (ichchha) to curse yet the curses are being hurled Dada has said that
You will become free You will certainly go to moksha - for sure!" Just that, visibly your vyavahar will not look beautiful
what is inauspicious (ashubha) vyavahar? One causes suffering (dukh) to others
There is violent intent (himsak bhaav)
Impure (ashuddha) vyavahar is terrible What is ashuddha vyavahar? One is hunting, is killing deers wild animals is killing wild animals
That is called ashuddha vyavahar very few people would do this [kind of vyavahar] Not everyone would do this One would have to go to hell (narak)
One acted violently towards someone - killed them Ashuddha vyavahar [It is] terrible
Aren't there these people who kill throngs of people? For the sake of their ego (ahamkar) they blow them up they indulge in [acts of] terrorism That is all considered ashuddha vyavahar
The one who [kills] binds less demerit karma (paap) But the one who instigated it [the killing] binds [more paap] The one who commits the sin (karyu) causes someone to commit the sin (karavyu) instigates someone to commit the sin (anumodyu) the one who cause others to commit the crime, and the one who instigates others to commit the crimes for these [two] the faults are graver
And in the case of ashubha vyavahar A person will have to act in that way For example, one will have to hunt deers he may be living in the jungle but he does it because he has no choice he doesn't have anything to feed his children so he does it forcibly [hunting the deers] [he feels] "instead of my children dying of hunger
he is remorseful (prashchyataap) the vyavahar is the same [as the other killer] but since his internal state of being is different so instead being considered as impure (ashubha) it is called inauspicious (ashuddha)
and the one who is in shubha [vyavahar] will remain hungry he will say "Even if I receive only flat bread after four days I will eat that but I will not kill" The one who is in shubha [vyavahar] is like that he will not pose as a hindrance to anyone
he will be adjustable he will not do anything that will cause suffering (dukh) to anyone If someone says to him "you won't get food today" "eat khakhra (indian flat bread)"
That is considered ashubha [vyavahar] And in our shuddha vyavahar In Akram
Despite that, when he [file 1] does something wrong, Then we [file 1] should do prashchyataap and pratikraman "This [behavior] is wrong.
then we are able to become free and this vyavahar comes to an end it is nikali because what lies at the root? That [fact that] "this is not mine"
So one of the areas where this kind of ordering process takes place in social network analysis is in measuring the centrality of different nodes. We talked a little bit about centrality in the previous unit, but let me talk a little bit about some different types of centrality that you might find useful. One that we're going to return to, and we've already kind of touch on is this node of closeness centrality.
Welcome back. Well I'm now going to do a presentation on how to essentially invert the chain rule or reverse the chain rule, because we're doing integration, which is the opposite of taking the derivative.
If I were to take the derivative of f of g of x-- hopefully this doesn't confuse you too much. I'll give another example with a concrete f of x and a concrete g of x. If I want to take the derivative of that, the chain rule just says the derivative of this composite function is just the derivative of the inside function. g prime of x times the derivative of the outer, or kind of the parent function, but still having g of x in at times. f prime of g of x.
Image invert colors. Let me rewrite that. The integral-- if I have g prime of x times f prime of g of x dx, then that is equal to f of g of x.
What is the integral of let's say sin of x to the third power dx. That's often written like this. That's often written like sin of x.
We're asked to solve the proportion 8/36 is equal to 10/n. So we need to figure out what n is. And the easiest way to do this is to multiply both sides of this equation by both denominators.
The whole purpose of doing that is so that this n in the denominator will cancel out with this n, which is essentially in the numerator. You can view this as n/1. So if you do that, the left-hand side of our equation becomes 8/36 times n, or you can even view it as 8n/36 because you can really do this as n/1.
36/1 is the same thing as 36. This 36 cancels out with that 36. And on the left-hand side, we have 8n, and on the right-hand side is equal to 10 times 36 is 360.
left-hand side, the 8's will cancel out, and you are left with n is equal to 360 divided by 8, and then we can figure out what that actually is.
8 goes into 360. So 8 is divisible not into 3, it's divisible into 36 four times.
4 times 8 is 32. Subtract.
6 minus 2 is 4.
3 minus 3 is nothing.
Bring down the 0.
8 goes into 40 exactly five times. 5 times 8 is 40, and then you have no remainder. So n is equal to 360/8, which is the exact same thing as 45.
So going back to our original proportion, we now solved for n, and we know that 8/36 is the same exact thing as 10/45.
Well it turns out all these are sort of right. You really do need to give the answer. Well this isn't quite right.
The mistakes of kshaya - vishay that have occurred for those whom we have meet in our lives In this matter, Dada usually says that from childhood up until the present Each and every person

we're used to seeing things from a particular point of view that is from a particular frame of reference and things look different to us under different circumstances at the moment
you look to queue here you're upside down you're the ones upside down no europe turns out well not he's the one that's upside down his name well let's talk for a
hi you lose people want to really up that that you better come into my frame of reference now
frame of reference was inverted from what it usually is that view of things would be normal for me if i normally walk to my friends this represents a frame of reference just three route that together so that peace is at right angles to the other two now i'm going to move in this direction if either plane at the same spot on your screen but you know i'm moving that way because you see the wall moving that way behind me but how do you know that i'm not that i think bill and the wall moving workable now the wallet that the pier and you have no way of telling whether imovie or not but now you know that i'm moving the point of it is that all motions it's relative in both cases i was moving relative to the wall and the wall with moving relative to me all motion is relative but we tend to think of one thing is being fixed and the other thing has been moving we usually think of the earth inspect and walls are usually pick to beer so perhaps you were the part of the first time when it was the wallet was moving and not doctor whom a frame of reference text of the earth is the most common frame of reference in which to observe the motion of other things that is the frame of reference that you're used to the framers baton to the table the table is bolted to the floor the florida anchored in the building and the building at firmly attached to the earth of course the reason for having three rods if the position uh... any object such as this fall can be specified using these three reference line this reference line points in the direction which we called up two different directions here than it is on the other side of the air and these two reference lines specify a plane which we call horizontal or level in this film we're going to look at the motion of object in this third frame of reference and other frames of reference moving in different ways relative to the other frame well let's look at a motion this field ball can be held are by the electra mode no i'm going to open the switch and you watch the motions of the ball the ball is accelerated straight down by gravity along the line parallel to this vertical reference blood as you can see the electromagnetic mounted on the cockpit can move i'm going to do exactly the same experiment the doc resume did but this time while a cart is moving at a constant velocity is pulled along by spring which is longer on this photograph turntable and that hold that with a constant velocity when the car passes this line be lol this week that you can see i'm going to start the cart down at the end of the table so that by the time it gets to this point by can be sure it's moving with a constant velocity i want you to watch right here so that you will see the ball falling
i think you can see that the ball landed in exactly the same position of the did before when doctor whom did the experiment with the car text but this time the ball could not have fallen straight down let me show you off the ball was released at that point if it had fallen straight down because the cart moves on in the time to take the fall would have landed back here somewhere but it didn't wanted to do the experiment again best time i'm going to let you watch the motion through slow-motion camera which is fixed the cart moves by the ball will fall and you can watch a missile which the camera
how true this again first-time there'll be a line on the film so if you can see the fat repeatedly complete but the problem all to the ground all of this has been in a frame of reference fixed to the year all of this motion locked in a frame of reference which was moving along with the car frame of reference like that well so that you can see what it looks like i'm going through solution camera so that it was with the car permittivity experiment again incidently i started and the number to stand here when the ball for all of you will have something which is fixed as a reference point
in their moving frame of reference i think you can see but the problem all as a political straight line it looks exactly the same as the day before when doctor whom did the experiment with the car etc if we were moving along in this frame of reference and we couldn't see the surroundings then we wouldn't be able to tell by this experiment that we were moving at a constant velocity as a matter of fact we wouldn't be able to tell by any experiment that we were moving at a constant velocity i'm gonna do the experiment once more and this time i'm not going to stand here behind the ball at the fall so that you won't have any fixed repertoire
as far as you're concerned that time the karke wasn't necessarily moving at all that time when you couldn't see the background then i think perhaps it was harder for you to realize that you were in moving frame of reference important thing to realize here all frames of reference moving at constant velocity with respect to one another are equivalent doctor ivy showed you but the motion of the ball that was released from the moving karte looked like in the current frame of reference and in the car frame the motion looks simpler from a car now i want you to watch the motion white spot would probably be the clock moving out circle
but that is what it's practiced actually like in the hurt of reference this is your normal frame of reference you father thought moving in the circle because you're high moved along with the car you put yourself in the frame of reference of the moving truck so if it isn't always true that we view motion from the third frame of reference when the motion is simpler from the moving frame you automatically put yourself and not moving frame now we're going to do another experiment on a relative motion to show how the compare the block today of an object in one printer records to explore all serbian another frame of reference forgiveness drive a spark a certain stark it moves a straight across the table with a speed which is essentially constant because the forces of friction of the made very small this is just the law of inertia an object moves the constant velocity unless an unbalanced force acts on it how you get the same start backwards uh... dougherty and gives it the same started moves back in this direction with the same philosophy now we're on a car here a car which can move in which were you going to move in this direction and we're going to repeat the experiment all right let's go
if we were making measurements here then we would observe the same but lots of these that is the same experimental results that we did before and so would you because you are observing this experiment through with the camera which is fast into this car added you were in the moving frame of reference but now we're going to do the experiment again and this time you watched through a camera which is fixed in the poor frame of reference or concentrate on watching the clock to lecture i follow us i think you'll see that in a move faster that way and not so bad this way relative to u_n_ relative to the wall husband
here the car which was moving along in this direction with the velocity we were thinking on the card at a table here i am over on the side and uh... doctor doom was on the side and we were pushing back-and-forth on the table well i pushed it and went into this direction with the velocity v when doctor didn't want to do when in this direction the same velocity v but this is the velocity relative to the car what about the velocity relative to an observer on the ground in the picture brain well if it was pushed in this direction it's velocity to you plot being if it's in this direction it will also be used u minded b this is all very reasonable is nothing very hard to understand here the surprising thing about this expression is that it is not actor in all circumstances at very high speed by high speed i mean speeds close to the velocity of light expression breakdown at these very high speed we have to use the ideas about relative motion developed by a albert einstein in his special theory of relativity for all the speed of the we're ever likely to run into this expression you plus or minus the is completely adequate so far we've been talking about frames of reference moving at a constant velocity relative to one another now i'm going to do the experiment with the dropping ball again only that time the karte will be accelerated relative to the earth frame these weight will fall and give the cart a constant acceleration first of all out and then i'll really put the motion is very fast and i want you to watch at the point where the ball is released from the pic camera i don't know whether you thought that are not at the top of the vault with the things that was before for either prime it landed in a different spots this is because the cart kept on accelerating in this direction as the ball was falling now i'm going to let you see it again with the slow-motion camera fixed on to the car
this time you saw the bull moving off to one side falling down the vertical reference line as it did in the constant velocity case but suppose you were in the six telerate a frame of reference how could you explain this gravity is the only force acting on this fall so it should fall straight down but at the law of inertia is to hold there must be a farce pushing sideways on the ball in this direction accorded to deviate from the vertical path but what kind of a force is it it is not gravitational or an electric or nuclear force in fact it is in the force at all as we know what story left to conclude but it gets sensor is no force that could be pushing in this direction on the ball but the law governorship just does not hold this is a strange frame of reference we call a frame of reference in which the law of inertia holes and inertial the law how the nurse or holds in the third frame of reference so it is an inertial frame the car moving at constant velocity relative to the earth is an inertial frame but the car which is expel a rated is not an inertial frame because the frame of reference that we're used to living in is one in which the law of inertia holds when we go into a non inertial like the frame of the accelerated car our belief in the lava nurture is so strong but when we feed them acceleration of the ball sideways we think there is a port carpet so we make fiction but they're into force and sometimes we call this fictitious force fictitious forces arise an accelerated frames of reference the frame is accelerated in this direction so you in the frame cn acceleration of the ball in this direction and you say that there is a force cutting it
what's happening this time why doesn't the talking straight across the table i did it before how you can see it doesn't if we believe in the law of inertia but we must believe that there is an unbalanced force to change the velocity of the pot but this pope is nearly friction locks so what can be exerting this unbalanced correspondent though that you watched the motion this time through a camera which is fixed in the earth's frame of reference
i think if you concentrate on watching dot papa you can't be that it is a warning is a great time and that therefore there is no i'm not quite acting on it
now we're going to stop this rotation but i can talk to you about what is happening here i don't know about you but i'm busy in d fixed fame of reference there was no one balanced force within the frame of reference for taking in this turntable there was and unbalanced because the velocity kept changing was with the fictitious part rotating plane is unknown inertial or accelerated fame just as the accelerated frame of the karte the doctor humes showed you you know that every object which is moving in a circle has an acceleration toward the center of the circle this is the exploration of has a special namely and capital acceleration now you will this puck for a while workstudy while the turntable is rotating i'll get off theoretic i'm ready but the rotation
you concede that now the park isn't moving in a circle dr humans exerting a force to keep it moving in the circle and you can see this from the fact that the rubber ring is extended heat is exerting the center of the billboards and this is the only horizontal force acting on the part but not let's look at it again from his point of view in the rotating system he is exerting a force towards the center of the table and yet the puck is standing still produced more or less taylor some vibration how he believes in a lot of inertia so he thinks there's and equal parts on the part away from the center of the table so that there is no unbalanced boring this outward force in the pocket the fictitious sports in this case sometimes it's called the centrifugal force in the pics reference frame there is no award boris on the path now suppose the doctor doom stops exerting a barge watch the pot in the picture frame of reference the puck moves off in a straight line there's no no unbalanced boris acting on it now let's look at it again from his point of view in the rotating system when he releases the proc which to him was everest it mood the force away from the sender is now on unbalanced part on the talked to him the outward course on the part is fictitious in our food frame of reference it doesn't think that's but the doctor whom in the accelerated frame of reference it's a perfectly real force i hope by now doctor i do not have convinced you the rotating frame of reference is not in their shel frame for you've all been told that the hurt it's rotating abode of taxes and that also it travels in a nearly circular orbit around the time why then do we find in a frame of reference attached securely to the earth but the law of inertia seems to hold why don't we observed fictitious forces the five of the fictitious forces which we have to introduce in a non initial frame depends upon the acceleration of the frame these smaller the acceleration is v smaller the fictitious forces that we introduced here's a frame of reference attached to the equator of the car the acceleration of this frame is really very small because bearded spinning about it axis it has an acceleration directly inward app three d_ one hundred of a major per second square on they one kilogram at the equator their is the fictitious for us directly upwards out three one hundred but this is not by gravity which is a port downward of nine point eight new so the net downward force is smaller than that of gravity alone if i've dropped av one kilogram at the equator the acceleration would be slightly smaller than that due to gravity alone very much now the acceleration of the car in its orbit is even smaller still and produces even smaller affect in our frame of reference mike said that the earth was rotating abode faxes how do we know but this is slow well if you take a time exposure photograph of the stars they seem to be moving in circles a both p pole star but all motion is relative is there any way of telling which is moving or the stars the fact that it is because which is rotating can be demonstrated by means of the pendulum if i've got a pendulum swinging its wings back-and-forth in a plane though it turns out is this pendulum with the north pole of the art the plane of swing would remain fixed relative to the stars but would rotate relative now i'll have to show you what i need this pendulum is epicenter how this turntable which will represent europe no i was about the cable turning around in this direction i'll put a black arrow on so that you'll remember but the rotation the pendulum is that the north pole of the earth annuals motion as you ordinarily do standing on the earth the playing of swing rotates in the opposite direction from the rotation of the turntable and that exactly the same rate now look at it from the fixed cabral which will represent the frame of the stars the turntable the alert rotate but the plane of the pendulum remain specs a pendulum used for this purpose because approval pendulum use tommy dot wong at the beginning of this film let's look back again now the focal pendulum dropped slammed as its wings i think you can see the paint line where the planned trail began the amplitude upswing is decreasing the famed trail is not long now but the important thing to speak is that the plane upswing has been rotating during the half hour that we've been talking to you an inertial frame of reference is one in which the alarm inner cities without all frames of reference moving at a constant velocity with respect to an inertial frame are also inertial frame we use the word as an inertial frame of reference but it is only approximately one a small acceleration with respect to the stars for example the frame of reference other stars is the best we can do when we look for a frame of reference which is for all practical purposes bextra accelerated frame of reference is not a member shall frame and when we are in an accelerated frame we have to introduce forces which we called fictitious forces in order that the law of inertia and the other laws of physics don't change
So rather than just talk about this to death, let me use the example that we use throughout the lectures and this is just the team that actually did this in five days not three weeks. There was a team at Columbia University called Jersey Square, and they were a rental service for professional sports jerseys and in five days they did 169 interviews and had 190 people share their website and they actually sold 2 of their products five days from a raw idea into a business. So on day one, these were their initial hypotheses coming into the class.
"We don't even believe that there's market here. What's the total available market then? Is this like a hobby or a business?
All of the work we've been doing so far with line integrals has been with scalar functions or scalar-valued functions. And when I say that, that just means you give me an x and a y and you evaluate the function at that x and y, and you get another scalar value. You get just a number.
The actual coordinate in r2 on the Cartesian coordinates will be x of a, which is this right here. And then, y of a, which is that right there. And we've seen that before.
And I'm specifying that because, in general, when someone talks about a vector, this vector and this vector are considered equivalent. As long as they have the same magnitude and direction, no one really cares about what their start and end points are as long as their direction's the same and their

Use the commutative law of addition-- let me underline that-- the commutative law of addition to write the expression 5 plus 8 plus 5 in a different way and then find the sum. Now, this commutative law of addition sounds like a very fancy thing, but all it means is if you're just adding a bunch of numbers, it doesn't matter what order you add the numbers in. So we could add it as 5 plus 8 plus 5.
These are all going to add up to the same things, and it makes sense. If I have 5 of something and then I add 8 more and then I add 5 more, I'm going to get the same thing as if I had took 5 of something, then added the 5, then added the 8. You could try all of these out.
13 plus 5 is also 18. That is also 18. If we go down here, 8 plus 5 is 13.
13 plus 5 is also equal to 18. So no matter how you do it and no matter what order you do it in-- and that's the commutative law of addition. It sounds very fancy, but it just means that order doesn't matter if you're adding a bunch of things.

Now let's pray for Raghunath soul.
May The Lord grant absolution to Raghunath's soul.
Grandma, what was my papa like?...
Used to be very naughty.
From the time he was born.
- You want to know about your father? - Yes.
Playing marbles! 2 days before your exams? Moron!
- Go on upstairs.
- I stand to lose 5 marbles!
Your dad slogs it out at the mill. Some day he will die of tuberculosis... Doesn't mean a thing to you, does it?
You're still pushing matriculation!...
And your younger brother has graduated already.
Why don't you drop out of school?
You're squandering my money.
As if your hooch comes free. Now you hear me out Raghu.
- You.re going to pass matriculation.
- After how many more attempts?
I'm rooting for a strong base.
Hey Ramnikial! Hey pimp!
Look! My dad's beating me up!
Why are you abusing him? - Don't you hit me. Dad.
You're a graduate. Why don't you drill some sense into this ass?
If I try to.
I'll end up unlearning whatever I've learnt... - But he's made it to class ten now. - Sure, I have...
- A couple of years to each class.
- Just let me clear matriculation... then I'll score straight 0s in the intermediate exams.
And then, I'll become a doctor.
Directly...
Dad. Give up alcohol. Try yoghurt shakes instead...
- Ramnikial! My Dad's bashing me up!
- Shut up! For heaven's sake!
- Hello Uncle. - Pooja, welcome...
Idlis! Pooja, you're a darling!
Thanks. I was famished!...
They don't make it as delicious even in idli-country.
- He's shameless... eating it all alone.
- Mom, tell Dad not to call me that!...
His fly is open. How about that?
- What do we do about this fellow?
- Forget him.
Why are you standing? Sit down. I'll get you tea.
- No, thanks.
I'm getting late.
- You're always in a hurry...
Eat one.
Go on. Eat it up.
No more melodrama.
I'll take a walk.
- Where is he off to? - After her.
- How long are we to meet on the sly?
- Till we're married.
- Will we ever get married? - Of course we're getting married.
As soon as I get a job. And well make a home for ourselves.! Just you and I.
- Somewhere far away from this place. - Why? What's wrong with this place?
You and I don't belong here. Such creatures live in this place...
Come on wife, give me 15 bucks...
Your darling died doing house keeping jobs for a living!
And you blow up more than half of what I earn on hooch.
I guess the British left you behind. 15 bucks please. This last time.
- I've been hearing that all my life.
- This drunk is getting on my nerves!
- Only 15. please. - I told you I don't have it.
- You have the money. I know it.
- Leave me! - I wont! - Let go!
Dad or not, I'll break your bones!... whose bones will you break?
Who are you talking to?
- But Mom... - Break whose bones?
Your father's?
The man who fathered you... the man who brought you up? You want to break his bones?
He's unemployed because... his mill has shut down.
But look at you!
Shameless fellow!
You just sit at home.
Your mother slaves it out in other peoples. Kitchens.
Your father is unemployed.
And all you do is sleep and eat!
You want to break your father's bones? I'll break your teeth! - Let him go Aunt.
- Get lost!...
Now stop crying like a sissy.
- all of us.
- Who knows?
- Why are you laughing? - Must come here and see!
- Look! Over there! - They're stealing bananas!
Where did this fellow come from? Where's my book? Over there... get lost.
- Where's Raghu? - In there. Been studying all evening.
Studying what?
Studying physics out of a math text book?
Carroms?
The chalk is still showing. Now come for dinner.
- Waste of time. - Hi Vijay!
- What's it? - Nothing. - Like bananas?
- Shit!
Give them to me.
- Where are my bananas?
- Those were. Gone now.
Shut up!
- First ask what it's all about. - We never asked?
Well what? Landed a job. Sub inspector of police.
Really?!
- Party! Party! - Shut up!
- Who need's money? On sunday we will raid Dagdu's chicken coop.
Say what?...
Raghu!
Get up!
- Why are you fellows screaming?
- Dagdu knows we stole his chicken.
- How do you know he knows?
- He's screaming his head off.
- Why did you fellows come here?
- He's going to your house!
- I'm in a fix! - Come on. Raghu...
Go on.
Let him do what he wants.
We will see later.
Shut up and leave him alone.
Narm deo! Come down! Look what your son did!
They stole two of my chickens!
I'm not going to spare them!
They're out to ruin me!
- We are coming.
- Just you come down!
You aren't digesting my chicken! I wont spare anyone! You thieves!
The leader! The king of the loafers!
You ate all my chicken! I will hand you over to the police! Shut up, Dagdu.
Don't pick my brains fresh in the morning... Did you steal his chicken?
- Who says?
- He's saying!
Bones! Chicken bones! My chicken!
The ones you cooked last night! - On the terrace! I found the bones!
Does the name on the bones say Dagdu's Chicken...?... will you never mend your ways? You're such an embarrassment!
Who pays for my chicken?!
Take that. - What's happening? - The usual.
Studying... to become a doctor!
Why are you tearing his books? Books are sacred!
Doesn't make a difference to him!
Look at him staring! - Why, what have I done? Look, Dad is bashing me up!... shut up!
Shanta, your son is making life very difficult for me!... if you want to live in this house, you will have to do something...
All right, drop out of school and find yourself a job.
- Look at him laughing!
Scared!
Why don't you start a small business?
Say something.
- Mom, has he been drinking?
- Shut up, you fool... Now what job does he do? He's a fitter in a mill.
And he talks business.
Dad, business needs capital... if he's saying it, there must be a reason for it...
- He can't even run a business. - Ideas.
I've always had them.
- Can you spare 40,000?
- To do what?...
- To set up a fast food kiosk.
- Fast food! Fast food isn't small business.
Take Laxman's kiosk. He takes home 5000 a day. And he buys his supplies from Dadar.
I will buy mine from Byculla and Nasik. Directly.
I will make a killing out of potatoes and onions.
Laxman sells a dish at 12, and he makes a profit of 4.50...
I will sell for 10, and I will take a profit of 5...
He sells 300 a day.
I will sell only 200.
- Enough! - Listen to me! - Mom!
- Shut up! - You still won't give me the money. - I will.
I will borrow from my superannuation fund. - You won't fritter it away, will you?
- No way! I've made it!...
Gone down the drain... she broke the coconut with one blow.
Business is going to be great.
Bless me Dad...
- Darling, how about a 20? - Kill me! Sell my bones!...
Just this once. Tomorrow, I will kick it...
Some day you will kick the bucket.
- Hey old girl, what are you doing?
- What do you think? Ajig!...
I'm trying to make a leaky stove work.
- Then dump it.
- Dump it?
- Then what will you eat? Stones? - Not stones.
- we will cooks feasts every day. - Feasts!
Did your mother hit a pot of gold when she was washing dishes?
Drop the sarcasm.
Keep this. Money.
From tomorrow, you aren't working. The old girl is going to sit at home...
Your son is going to make a living.
How about a drink, old man?...
Got this. For you. I will treat you to booze every day.
But don't you bother your old woman anymore.
4550... 4600... 4630! - That's a lot of money. - This is just the beginning, Dad...
And Dad, that Laxman is effed!...
I will pay your loan back in a trice.
We're waiting for you... why?
Ardent you coming to collect donations for the Govinda festival?
You go ahead. I'm not coming.
No one will contribute unless you come along.
Just take money from those who want to give.
This time, I'm sponsoring the celebrations...
We couldn't take the prize at Vijaynagar this year.
- 'You've made 14'000 bucks in all. - Shorty took a nasty fall...
- I saved him today.
- I fell because you stepped away.
2 breads over here.
The festival is over.
Back to work. Two breads over there.
- Clear the plates over here.
- Shorty take his check... Mangya, please go over.
My back is still hurting...
You're just lazy.
Move it.
It will be your turn someday.
Then I will see.
- Great piece of ass!
- Hey beauty!
- Wait till I get back.
- Just like Helen!
- So how did you like the pav bhaji?
- Just clear the plates, smart ass...
- Your bill is 220.
- For what?
6 bhajis, 1 khada bhaji, 20 pavs.
5 puffs, 20 papads. That's cheap... - 'you want money from us?
Just take the plates, and get lost.
Want money, you bastard?... why are you using foul language?
So what if he did? He called you a bastard. So what will you do?
- Whoever you may be... just pay your bill.
Munna. That's my name.
Get it? I'm Bandya's brother.
I will carve you up!
Right here.
Leave him, boss!
He made a mistake...
Tell him that.
You want to run a business here?
I will kill him!
He asks me for money!
You're the boss! I'm apologizing for him. Please.
He made a mistake.
He's out of his mind.
Don't you fellows put on airs! - You're supposed to be meek.
- He's the one who hit me.
- In business, you have to... - why pick a fight with Bandya's men?
- Was that written on his face?
He should've said that he's Bandya's brother.
He should've said he hasn't the money and should've begged for food.
- Now cool down. - The next time... I'm not going to spare anyone.
Don Shorty!
- Why are you so glum? - What else do I do?
Dad put you up in business. And I am where I was. Unemployed.
Pooja's dad is going to get her married to someone very soon.
Once you get a job' you can get married...
- Job? Where?
Everyone wants bribes. - How much?
- Why do you want to know? - Just tell me.
- You can have it in two days... - where will you get so much?
- Not your concern.
Now stop moping. In a week's time' I will talk to pooja's dad too...
Hi Uncle, how are you?
Praying, I guess?...
Hey, isn't that a brand new tv? Solid piece...
Your hotel must be doing well. I have put up a kiosk too.
The daily take is about 5000.
Come over to the kiosk someday. I will treat you to great pav bhaji. And Vijay... he has a job now.
I put up 25,000, you know. I took it from Govind bhai...
I will pay him back in 2 or 3 months. And I thought, why don't I drop in to see you?... - why?
- Life would be great once...
- my brother and pooja are married.
Get up.
- What happened, Uncle?
You run a pav-bhaji kiosk!
And you think you're an equal?
I felt like slapping the old man.
- So, Vijay's wedding is off? - I've told Vijay... to lie low for 2 months.
And then, elope...
The tensions ease in a month or two ...the girl's parents fall in line.
Like that girl on the second floor who eloped with Keshav 6 months ago.
Now they're back at home.
- News is she's pregnant.
- Keeping track?
Hey jerks, over here...
Here come the beggars.
Satya, take the order...
oh, yes! The bloody beggars!... - what will you eat?
- The same.
2 khada bhajis. 1 bhaji, buttered.
8 pavs...
- Want some puff? - Sure.
2 buttered puffs. Get lost. Munna, what about the jerk we saw yesterday?...
Hey, come here... where's the jerk?
- Call him over here. - Forget it, boss.
He made a mistake...
- He doesn't have brains.
- You monkey. Just do what I tell you...
Else, I will bash your ears in. Get going... Forget him, boss.
Get lost.
Munna, let's get into the mood...
Just listen to them. Don't talk back. They're drunk.
Hi jerk! You won't ask us to pay up today?
Did the cat get your tongue' you bastard?...
Look at the anger in his eyes! Oh I'm scared!
You won't talk back?
Speak up!
- Why are you hitting me? - What will you do?
You fellows are eunuchs! They are bashing your friend up!
And you fellows are just enjoying the show?
What will they do?
You think you're a don?
You think I'm a coward?
Kill him!
Over here.
What have you done?
You scoundrels!
You've destroyed everything.
I didn't mean to kill him. But he would've killed Shorty.
What's going to happen now? My career is ruined!
Shut up Vijay!
Get up, and come with me to the police station... Go the police, and They're dead.
The police are in Bandya. S pay...
- Then what do we do?
- I'll still go to the police.
- All policemen aren't bad.
- Yes! No!
Listen to me.
Do what I say!
- Run! - No! Raghu!
Where have you hidden Raghu?
Or I will break your bones.
I have told you all I know.
- You're lying! - He doesn't know anything.
- I know nothing! - You're in it together. - I will fix all of you.
- Put on airs, have you?
- Why are you beating him?...
- if he doesn't know, he doesn't know.
Arguing with a senior? A policeman interfering with an investigation. I will have you suspended.
One last warning for all of you.
If I don't get Raghu in 2 days' I will make you march stark naked...
Don Bandya is making life hell for us all because of this Raghu.
So what if you voted for me?
And what's so great about what he has done?
He killed someone.
- What use coming here? - He wants to surrender to the police.
- So what do you want me to do?
- The police should...
- treat him properly.
- Why, is he a politician?...
kishore! Good you came!
Look, turn us over to the police...
Not now. The case is hot. Bandya is baying for blood.
- How long do we sit here?
Been 3 days since I ate or drank anything. - 'You have to hide. For a few days.
- Come with me. - Where?
- Only one person can help you now. - Who?
One-Eye Vittal
You did the right thing.
Mean pimps, those Bandya brothers. Good you killed the snake...
We didn't mean to kill him.
But he would've killed Shorty.
What do you want from me?
- We want to surrender to the police.
- The police has sold out to Bandya.
No one can help you there.
But there's one thing I can do.
Till the heat is on, you can stay here...
Have no fear. In here, your lives aren't in danger...
Hungry?
You haven't eaten?
Give them food.
- Thank you. - Don't mention it.
But you did the right thing bringing them here.
Now let's see what Bandya.
S gang does.
- Sorry about your brother. - That's why I am here.
- Come inside.
We talk here.
- Because we want to kill him.
One life for another!
- Whatever happened was an accident. - The dead man was my brother.
Suleiman name your price. I want Raghu. Ant any cost...
Raghu doesn't belong to any gang. I don't know where he is right now. I'm a peacemaker.
If you want to save a life' name your price... 2 million
- We lost our brother. - Shut up. 2 million?
- One-Eye Vittal will pay. - Why will he pay? Only one man in this city could give him shelter.
So go and tell him that if he wants to save his dog... he will pay up 2 million.
No deal. He'll take his 2 million' and he'll still kill...
- I don't trust his word.
- Trust my word. Five years back, that cur was working for me...
And he stabbed me in the back! No deal! I do my namaaz five times a day.
Even if I have to pay for it with my life...
I will make sure these men will not be hurt.
If you say so, I will pay up...
Go in.
You must be wondering why I agreed to pay 2 million.
'You know, time was when one-Eye Vittal used to rule Bombay...
They are going to bring those days back.
Oh I forgot, you don't touch cigarettes or alcohol...
- How do you stay alive? - That's just why I'm alive.
- What date for the deal? - Day after tomorrow.
Evening. - Where? - Cafe Britannia.
But one-Eye Vittal is a criminal' a murderer! And Raghu is with him?... I knew this would happen.
Raghu isn't responsible for whatever happened.
I hear one-Eye Vittal is settling the matter between Raghu and Bandya.
Then Raghu will turn himself over to the police.
- When is this going to happen? - Tonight.
I taped the gun under that table.
Why did they make us sit here?
I don't understand a thing.
Go on. Frisk me. I am not carrying guns.
No.
Call them over here.
Here it is.
What happened? The 2 million is in it.
Keep it. Not the money.
I want these two. You gave me your word.
I'm taking back my word. Can anyone do anything?
What about my word?
Does it mean more than my brother's life?
You dogs! Got fire in your veins?
It was a mistake.
Please forgive us.
Shut up! I will douse the fire tonight.
Scared? The sight of death scares you?
You killed my brother!
You jerks!
Why are you wasting time?
Just kill them!
Raghu, try to understand what I say.
Get this clear... - These men deserved it...
- Don't touch me!
I'm a murderer!
- Turn me over to the police!
- They will kill you.
What difference would it make? Let them kill me! I'm a killer!
If you didn't kill them' they would've killed you!... why don't you get this?
Drink.
- No! I don't drink! - Drink it up.
Like medicine.
Drink it. It's medicine.
Mom, what makes you so angry?
This is your Raghu...
Dad, scotch for you. It's foreign, you know...
A watch for you, Vijay. And a dress...
Mom...
look, a saree for you...
- And look at this... - Are you trying to buy us out? - It's a gift of love.
- Take everything away. - I didn't bring it to take it away. If you won't have it' throw it away...
Looking at that? It's real gold. 550 grams.
How much? 550 grams.
Dad, look at her gaping!...
Want to see something exquisite?
Come here.
Get it out.
Look at this. ...take a look.
The gun. Worth two big ones.
Two big ones means 200'000 quid... Look at this Dad.
Mom, take a look... why are you sacred?
Let me show you.
This is called the magazine. You shove it in like this. And you call this the trigger.
Just curl your finger around the trigger and... you aim it at the mark. Squeeze the trigger... and the game is over!
Got it, Mom?...
Not afraid of the police anymore, is he?...
Bandya threatened him. He has already killed Bandya. There's still time.
No policeman in all Bombay dares speak up to me.
I rule Bombay.
Why arrest me?
No one can even touch me.
No, you won't understand this.
Forget it...
- So Vijay, how goes the job? - Depends on when I find a job... - But I gave you the money...?
- That money I gave him.
But he's always putting it off.
- Whom did you give the money? - Himmat Shah. Perfect placements.
Why did you have to come, Don Raghu?
I'll be mad not to give him a job...
He should've told me he's your brother.
- So when are you giving him the job?
- Right away, boss... please consider this office yours.
Secure job. Great salary.
Hey! Who are you? How did you come inside?
Home Minister Kadam himself!
In my poor hovel!
- Welcome, and sit down.
- I haven't come here to sit down...
Raghunath Namdeo Shivaikar.
Don Raghu. He could be useful for me.
- Setup a meeting.
- He's no use for you.
He has an independent streak.
He won't work under anyone.
We will see. What isn't possible, given the money for it?...
Work for me, and he could become man of millions. Setup the meeting...
There are other punters in Mumbai. Why have you come to me?
There's a big difference between you and the others, son... you are quite melo dramatic.
- Sure.
Suit yourself. - I name my price.
Sure.
- Then I've made it!
- This is just the beginning, son...
Don Vittai, keep this...
- What's this? - A good will payment.
- For what assignment? - No dearth of assignments, son...
listen to another corny line. It's fantastic!
There're no thefts in Nepal, you know... Because they're a country of guards!
- Stop it. You're a bloody hore. - What's up, Deva?...
Keep it, Kishan...
- What's this? - Just keep it.
You take it at the police station, don't you?
Oh come on, I know...
- I'm not taking hrihes from you. - It isn't hard-earned money.
And We're going to rake in more. Go on Shorty, tell him... That home minister Kadam is inside Raghu.s pocket.
- Raghu, stay clear of him.
- Oh don't worry... now what did I tell him? ...tell him Shorty. Told him, we will do only what we feel like doing... And I will take whatever price I ask for.
Raghu, are you on hashish?...
I will tell you what, the two of you should get married... only your wives can manage the two of you. It'd take madmen to give us their daughters.
And I get kind of tongue-tied in the presence of girls. One minute... come over here. I will let you in on a secret.
These days, the sight of girls turns me off...
I will solve your problem.
Just come with me.
- Where to? - To Heaven!
Come in, now. No tensions. Just come inside...
Hey julie, here comes your hero!...
That's me!
My hero!
What's up, julie?
Lots of English ...took in an Englishman?...
- English-talking, fluently! - My girl, after all...
Take a look around.
See if you like someone.
No tension.
If you don't like it here, I have other points...
look, over there. Hema Malini...
Go on. Take a look for yourself.
Like her?
Saydo you like her?...
Go on Sonu, take him in...
Come on.
Go on, buddy...
Don't you want it tonight? Come on.
Who do you think you are? Aishwarya Rai?
I just did it yesterday night. You think I'm Tarzan.
How about playing cards?
You can give me a massage.
I'm playing cards after ages.
Get me some beer.
Will you just go on staring?
Haven't ever seen a girl?
Come on, take your pants off. Don't waste time. This is peak hour...
Seen lots of guns. Even 12 year olds carry guns these days.
Put it down. And come over.
What happened? Got a shock?
- You're running a temperature.
- You want to take me to the doctor?
Just get over with what you're here for.
Don't you empathise or anything.
I'm scared of sympathies.
Go on, drop your pants...
- Sweets? What are we celebrating? - Vijay has found a lot.
Good.
At least one of your sons is making an honest living.
Now find a good girl, and get him married...
- That will help your wife. - That's why I'm here.
Balaji, you know it and I know it. Vijay and Pooja are in love...
- Why don't we get them married?
- That's on of yours, the loafer... he came to tell me that.
No problem even if my daughter stays a spinster.
- But I won't give her to your family.
Daddy, listen to me...
Go in.
You're still here? Look, he of you. Stop pursuing my daughter...
- Balaji, listen to me...
- Not a word...
Were it someone else, I would've thrown him out...
- What? He insulted my Dad? - Right.
- Threw him out?
- Right.
This fellow has airs... what's his name?
- Pooja's dad.
- Yes.
That's him.
He's getting some rich man's son to come and see Pooja.
- What...?
When? - Friday.
- The day after tomorrow.
Here, have some sweets. I've had enough, thank you... - just taste some.
Shall we fix a date for the wedding say two months from now?
So Uncle, how have you been?...
So this is the boy?
Nice.
- What do you call it?
- Smart boy.
- And those cars down there? - Belongs to them.
- How far has your son studied?
- Our son is an engineer.
Bless his mother!
Smart boy. Engineer.
Has cars. Don't you care for your son?
Why don't you find a good girl for your son?
Some virgin...?
Get out of here. And find a good girl for your son.
Let me tell you something...
Pooja will marry Vijay.
Get it?
This time, I'm talking.
Next time, I will pump in all six...
Rascal!
Won't you let anyone rest in peace?
- How much in it?
- 1.5 million.
- I asked for 2.5 million.
- Sorry, boss. Business is slack...
- I will pay you up in 15 days.
- No excuses next time.
Take it Rane.
It's for you.
- For news about one-Eye Vittal. - No need for this, boss...
Keep it. For a cop, your tastes are too extravagant...
- Anything else?
Let me know. - I want that pimp. Raghu.
Track Raghu for me.
I will make you the richest shop in Bombay.
Are we to sit idle? Come on, let's bust Bandya's gang...
That's just what they want us to do.
They must be fielding for us.
If we step out of here, they will take us out...
Are we eunuchs? Won't we avenge Don Vittal's death?
Sure. We will take revenge.
But all in good time.
There's a time for everything.
- No jokes? - I swear it. A two room apartment.
- The company is giving it to me.
- Really?
- I can move in next week. - Your Mom and Dad will be so happy! We are going to live there.
- Why? - I want to break away from my past.
I want to start a new life.
I don't want to be called Raghu's brother... But you don't mind keeping the job your brother fixed for you?
He might've landed me the job. But this esteem I have earned... this apartment I've been given, is my dint of my hard work... Raghu borrowed to give you the money.
You're selfish.
I will return all his money.
I might he leaving this house. But I'm not breaking ties.
- I will send you money every month.
- What are you saying, Vijay?!...
We aren't going anywhere Without your parents.
Nohe wants to leave. Go with him...
Why are you so sad?
I'm here with you.
Once their wings are grown, the fledglings will fly alone...
That right our children have too.
Onlythey don't have a sky to fly.
To this earth they are tied... an earth being divided into ever smaller squares.
Go on. We do not seek to intrude upon your lives.
- We only want to live in your hearts.
- In my heart you will live forever. I look at you, and I wish I had a daughter...
- What do you mean left home?
- You know they won't live with me. - I can't do anything.
I won't have anything to do with my past.
People who live here are gentlemen.
- What are you saying?
- What I'm saying is right.
And I'll rather you didn't come here again.
- Have dinner.
- Thanks, I've had my fill...
- Enough, Raghu. - Let me drink tonight, Sonu...
Scum!
He's scum.
I never imagined Mom and Dad would have to live all alone.
What haven't they done for him? Educated him. Made him a graduate.
And he gets married, and he goes off with his wife...
- Why don't you live with them?
- I'll take good care of them.
By that old woman, she won't live with me...
- Why?
- Because...
- Because... - What...?
Because she won't take my money. I'm into had business.
Why don't you give it up?
You can't, isn't that so?...
So there's no difference between you and Vijay.
He wanted happiness in life.
And all his life, he drank!...
What happiness...?
Nothing!
Wanted the son to do well in life.
He dreamed of better days... nothing!
- What's happening?
Did you call?
- I telephoned.
- Did you speak to Shorty?
- Yes. They should he coming.
- When did you come?
- A while ago. Coming from my hotel.
- When did it happen? - This afternoon.
- When is the funeral?
- His brother and sister are expected.
The funeral is tomorrow.
- Are you sure Rane? - Certain.
10:30 tomorrow morning.
- At the crematorium in Dadar. - Dadar...
- So how are you, Dagdu?
- Fine... just fine...
- you look disturbed. What is it? - It's nothing.
- Tell me. - The doctor says my daughter... - has to undergo surgery.
- What's wrong with her? She has a hole over here ...in the heart.
- It will cost 100,000.
- Take it from me...
- I will borrow it from Ram Niklal - On interest? You don't need to.
Take it from me. Say, I'm settling for the chickens I stole from you...
Wait here, please...
What's this crowd? Move aside.
- You're operating on my father?
- Yes. Why?
If anything happens to him, I will kill you...
Forgive him, doctor. I'm his wife. Please do whatever you can...
My son doesn't know that being a hooligan doesn't help every time.
Please proceed.
Don't cry.
Everything will he all right.
- Where's Vijay? - At office.
- He should he here soon.
- Dad is fighting for his life.
And he's still in office?
Tell him never to show me his face!
Else, I will kill him!...
Shut up you fool! You want to kill?
Whom?...
Why is your father lying here? Whose fault is it?
The doctor says he's out of danger.
But he needs blood. Can any of you...?
- Where are you going? - To give my blood.
Your blood is full of cocaine and alcohol. Just stay here. For my loved ones, even my blood is poisoned...
Suleiman, how does this gang manage to get news about us?... inspector Rane.
He's the mole.
- Where did you pick him up from? - A hotel. Was with a girl.
Picked him up in the middle of his act.
Where will I find him?
I will tell you! 10 tomorrow morning.
The whole gang is going to Shirdi.
- Shirdi?
- Yes.
See that van? They're in it.
The ambulance will overtake them on the bridge.
Let him pass.
Look! There's the dog!
What's going on in this city? Why are people paying for blood?
In Gandhi's country of non-violence, why are people becoming...
- worse than animals?
- Just what we'll like you to tell us.
- The goons own the government. We are trying our best... to root out terrorism from this state.
You've made a hero out of Raghu. You give him so much publicity! - If he owns the entire state!
- When I hear allegations like that... my heart weeps tears of blood!
In the service of the people...
I wake sleepless nights! And this is what you accuse me of!
Do I weep false tears for my people? Is this a put-on?
This grand standing makes you hell eve he's really a do-gooder.
Sonuyou look very happy... What's it about?
- Meaning, you're with child?... - yes.
- Just abort it.
- No.
I want the baby. - Why?
It's yours.
What...? What did you say? You hitch!
You want to saddle me with someone else's bastard!
You think you can trap me because I share a joke with you?
- I will kill you! - What are you doing?!
Drill some sense into her head.
She belongs to the gutters.
That's where she stays.
My baby? My baby! I will kill you!
Stop it now.
There's ethics in your business too.
I could raze this place, you know... - Now get out of my way. - Go, take care of him...
Raghu, listen to me. You don't get worked up over these small things...
- I didn't ask him to marry me. - I knew this would happen.
Women like us have no right to fall in love.
Here comes the girl on the third floor.
- Blossoming! But her man is worn out.
- The monkey doesn't deserve her.
What a swish-and-sway! Come on beauty, respond...
You're always taunting married women. Aren't you ashamed? Why be ashamed about being warm-blooded?
- Let go of my hand.
Pooja, listen to me. No point confronting them...
- why don't you just ignore them? - Ignore them?
This has gone from taunts to molestation.
- I'm going to the police.
- Pooja, try to understand...
Going to the police will only make things worse.
- Besides, we have to live here.
- I'm ashamed of you!... if you're so scared, just sit at home. I will go to the police station myself...
No...
Get lost! I don't want to see your face.
- Raghu, please listen to me. - Not one word!... Bloody white-collared wimp cant even protect his wife's honour!
- Get out of my face!
- Raghu, I beg of you!... Take him away! Or I will kill him!
Come on now, get up...
- But those men... - I will speak to him.
- Pooja cant even go to work. - I will take care of it.
He's too agitated now. I will talk to him later.
- Are the boys from that locality?
- Yes.
- He's your brother after all.
- Someone like that? Eunuch?
- Who are they?
- Pickpockets.
- New in that area, I guess. - Find out. Bloody jerks!...
Cash? Just put it on my account. Now get lost.
Are you his pimp?
Get lost!
Look at this monkey now.
You jerks, tomorrow onwards, I don't want to see you... in the area you work out of.
Get me?
Understand?
Why? Your father owns the area?
Why did the music stop?
- Go on girls, dance. - He's dead. Dance on...
- kill the jerk. - Shut your eyes now, jerk...
The minister has palmed this city off to the hoods.
The Hindu and the Muslim do not fight each other.
They are set against each other for political gains.
Kill a pig and throw the carcass into a mosque. Allah forbid! Allah forbid!
The old man just wont let up.
When will he finish his lecture? When will I kill him? When will I eat dinner?
- Why not kill just now?
- No, not you. I will kill him... - You don't trust me?
Why bother? We just took the contract. So we just kill.
In this land of Gandhi Nehru and Maulana Azad... some politicians are spreading terror.
Shall we stay mum?
No!
4 o'clock. At Azad Maidan.
Move it now.
Remember this.
The people are honest.
And the grace of Allah is with us.
- Son, what is your problem?
- You are the problem...
- I do not understand. - That's what I've come to explain.
- Come on. No point arguing with them. - You're going alone.
I have a score to settle with him.
Move it now.
- Go on, son.
I will join you.
- Fine...
Move it!
- Enjoy! We rule Mumbai! Say what?
Shorty. Why are you moping?
Here, take a drink...
- I'm not in the mood.
- Then make the mood.
Come with me.
- Where to?
- To Heaven!
- Not today. - You wont come with me? - Fine!
- Wait, I'm coming...
- But I wont go upstairs.
- Suit yourself. Now come along.
Hi, how are you?...
- why have you come here?
- To meet son... - Go away. No one here is for you.
Keep that.
Very proud of your money, are you?
You keep your money... with all your money, have you ever bought a woman's heart?...
Body is all you have bought.
And we decide who we sell to.
Now get out and don't ever come back!
Talk too much, and I will waste you!...
Waste me? You will kill me?
Go on! Shoot!
Lost your manhood?
You want to use that thing to get a woman's body?
How many of us will you kill? Mile, shobha, come over here...
Go on.
Just want to see sonu. For two minutes. Not for two seconds!
Let him come.
I aborted it... why?
I didn't want to breed the spawn of this gutters.
Come on. Come with me. - No.
Sonu, I will marry you...
Now don't create a scene for nothing. Just come along.
May the Goddess of Fortune favour you.
What's your name?
Sonia.
- Nice name. - And your father's name?
Had I a father to my name, I wouldn't have been a prostitute.
You must never say that. From today, We are your parents.
Now come on. Cut out that film scene.
Time to leave.
- I will come again, Mother.
I'm waiting downstairs. Hurry up.
Bye, Mother...
- Now what happened to you? - He married a prostitute?
So what? Your son is no doctor or engineer. He's lucky he found someone like sonia.
She will take good care of him.
- So how was the bhaji? - Super!
- Correct accent?... perfect!
Raghu trained her well, right?...
- How's business? - Super! Pull down that t-shirt.
I told you that's the last order. Out with the money, now pay up...
The don!
- What? - You didn't give him money.
What money?
3 special bhaji, 1 khada bhaji 1 puff buttered, and 10 pav extra...
You think they will take money from us?
Pay up.
I don't want you to create another raghu someday.
- And you're doing what she says? - Keep it. Else, she will thrash me...
- The tea is super! - Thank you. Imagine him drinking a late tea.
I'm here to tell you something.
Yes, go on...
Come on, outside...
- so what says you?
- Why did you kill that old man?
Why do I kill anyone?
For the money. 10 million. That's what I was paid.
He tangoed with our minister.
He told me to bump him off.
- Why? Are you related to him? - In the riots that followed... 30 Muslims died.
And 21 Hindus. And this pimp of yours... he gives it the colour of religion.
Not one, you've killed 53 people...
- You should've got 52 times 10 million.
- No place for arithmetic in my head.
Look, he gave us the contract, so we bumped him off...
But this shit load of tensions ...no not for me.
You used to say that you wont do it just because he told you to do it.
- You'll do what you thought was right.
- Had we brains enough we would've...
- made inspectors like you. What raghu? - Forget it.
- Clean collar. - No. White collar, we call it...
Listen to these white-collar types, it would be tough making altering...
But altering wouldn't be tough. Look, there's still time...
Get out of this. Or you will be sucked into the vortex. You might be doing these jobs for the minister.
But for the world, it's you who is doing all this...
Come the day of reckoning, he will wash his hands clean of you...
You're the one who's going to hang for it.
I rule this city!
I rule Mumbai! I've made myself! No minister made me anything.
I walk into your police station, and your bosses stand up for me...
- Tell him that. - How mistaken you are.
They don't stand up for you.
They stand up for your patron saint.
I will hear you say this the day he washes his hands off you.
I've heard enough of your lectures!
Don't you pick my brains.
- Else I will do it, right here and now.
- Leave him...
- at least listen to what he says.
Everyone's trying to make me see reason.
For the world, you might be Don raghu.
For me, you're the old raghu I knew... from the slums. Take an advice.
Calm down, and think over what I said...
I'm very angry with you. You married, and you never even told me...
- And I take you for a son.
- I did it in a hurry.
All's well that ends well. But do you know about a honeymoon?
- Did you take her for a honeymoon?
- I wanted to, but...
Bravo!
Two tickets to Switzerland. Hotel bookings for the stay.
Take her for a holiday.
What a lovely baby. Looks just like you.
You will have to bring your father around.
We are tired of telling him.
Tell him, that he must give it up for your sake... We are at the end of our lives. But your journey has just begun.
You will Tell your father, wont you?...
Yes raghu, your mother is right. The government is granting amnesty...
If the two of you give yourselves up... the court will let you go after a short sentence.
That's right, raghu...
And during those years, we will take care of your wife and child...
Afterwards you will live a free man with your wife and your children.
Think it over, son...
Ever since I was a child, I've seen these trains plying...
They run between VT and Dadar... Karjat... Kasara.
But They're always on their rails. Will they ever run on roads?
Will they ever soar into the skies?
All my life I'm stuck to the track. I can never change my track.
- But this life... finished. - I feel like slapping you.
Hey Ram Nikial... you pimp...
look, he's bashing me up!...
why did this have to happen to us?!
Even fake 500 buck bills have arrived in the market.
Be seated, khub chandani... Now he's done with me. And here's the next quarry.
I knew you'll come. You've been trying to grab Mr Parvez's plot of land.
- Any luck? - That parsee is very touchy.
At the drop of a hat, he runs to the cops, and he drags the press in...
I'm losing millions.
Want me to do it for him?
100 million for my party fund. - 100 million?! Good God!
But he will vacate, wont he?... stop being adamant.
The builder is paying you well.
Just take it.
The poor fellow is losing millions.
What will you do if I don't sell?
You will kill me, will you?...
But I cant kill you.
If you're dead, who is going to sign the papers?...
I'm not going to kill you.
But this boy, I can kill!...
Leave him, please! Don't let anything happen to my baby!... Give them the house!
Keep the house to yourself.
- Take that.
pay him up.
All yours.
Buy yourself a nice house, and live happily ever after...
Come on.
Sure, it isn't my time.
That's why I signed the papers...
But one day, I will fix all of you. First that cur! The minister...
Then you. And then that builder. Who do you fellows think you are?
You wont mend your ways, will you? Now what do they call it?...
- Clean collar. - No.
White. White collar.
Yes, these white collar types think they have what you call it...?...
- The wisdom of king Solomon. - Right!
Tell them to live in peace with their wives and their children... but no, they wont have any of it.
They want to prove They're heroes!...
After I leave, you're going straight to the cops, the press, the ministers...
And you will say that I took your house away perforce.
You will make life tough for me ...for my minister. But why?
Why take all the trouble?
Why did you uncork the champagne? The papers haven't arrived yet.
This is my champagne. What's your problem? - I thought...
- We will open another.
He rakes it in.
But he's a number one miser.
Pour it out.
Here comes your papers.
- So what happened?
- He signed.
Now live it up.
Tell me, where do you want the cash delivered...
I will pick it up later.
But there's a small problem. - Now what problem? - The old talked me out of my head.
- Wasted?
Too bad.
This is just too bad.
Do something. Go underground for sometime.
I saw nothing. I don't know who killed my husband.
I never even saw him.
Not because I'm afraid of you.
Because of my son. He's helpless in the face of your terror.
But don't you think no one can do anything against you.
I'm going to do something.
- What happened, raghu? - Nothing. Go back to bed...
- Don't chew my brains.
Go to bed. - It's 3 in the morning. You will wake up Idiot.
I told you to go to bed, you whore!...
whore.
Foul language for others.
But for me, the bitter truth... 20 years ago... he must've been someone like you.
He didn't leave me a name.
With so much love, my mother named me sonia...
But for the rest of the world, I was a whore.
Just a bad word... on one hand, you expect me to be a perfect wife... to take care of you, your house, your bed and your son...
But do you give me the status Of your wife?
No. For you, I'm just a whore...
I'm going out of my mind!
Forgive me.
Look at me... I cant even get sleep.
If I could only fall asleep in peace for just 2 hours, I'll give anything!...
I'm going out of my mind! Look... at my eyes. They're tired.
Tired of waking.
Going out of my mind!
Look how peacefully my son sleeps.
I want to sleep just like he does.
Two hours... can you put me to sleep for just two hours?
Every day he Tells me, Dad, take me to the beach...
Dad, take me to the pictures... Dad, buy me ice cream...
How can I take him out?
I cant walk in the open. How can I take you out?
I remember those days when Dad used to take to the beach.
He would put me on a horse.
I miss those days.
When I see people with their children, I feel like killing them!...
Going out of my mind!
Sonu! Do something!
I'm going out of my mind!
That's what We are doing at 3:30.
And where are we at 4:30?
At the hospital. I'm chief guest. And then at five... that thing about the kids ...some cancer or something.
- What's it? - A memo.
- From the party president.
- Read it out.
The press insists that you have close links with the under world.
Please explain your position. Falling which, the party will take steps to impeach you...
The old man has gone senile.
He cant even touch me.
I've spoken to the Chief Minister's personal assistant.
He was saying... your name doesn't figure on the list of candidates...
- for the coming elections.
- Hear that? For 25 years, I've been in politics. And he wont give me a ticket...
Type out a resignation, and give it to the press... Tell them that the governor can have my resignation after a week.
- Not but. if... if raghu isn't arrested in two days.
Alive... or... you get it?
Understood.
Understood? So you get it too.
Hi kishore! What brings you here?
- Where's raghu? - It's Eohit's birthday today. They have gone to the temple.
- Don't go there. - Why not?
You are to be shot at sight. Orders have been issued.
Take my advice, if you want to save your lives, run... - where's this temple?
Do you have a safe house somewhere? Some place no one knows about? Yes.
Take your family, and go over.
Else, they will be tortured...
Get going.
Dad, take everyone and go to my house in Alibagh...
- I will never set foot in your house. - I beg of you!
Everyone's life is at risk.
Just listen to me. For once.
Afterwards, I will do whatever you ask me to do... - where is this place?
- My chauffeur knows.
- And you? - I will come later. Get going, Mom.
Dad, please Tell her...
Take care of Mom and Dad.
Why have you come here? The cops are all over the place. This morning, the cops picked up shorty and the others... - what's this crowd?
- You know...
- Tell me, or I will slap you.
- There's news that... the cops killed two of your boys in an encounter.
What are you doing here?
Come inside.
Raghu, why did you come here?
- To kill me in an encounter. I know. - Then run away.
I will help you to cross over to Nepal... Dubai.
- You think I cant go myself? - Then get going.
- Shorty... - The cops have killed him. - I know.
That's why I came to you. - Why me?
I want to meet Kadam. For once.
- How will you get to him? - I will Tell you.
Home Minister Kadarm's residence... - suleiman Badshah here. - Yes sir.
I will put you through.
He's coming on line.
- Yes suleiman, what can I do for you? - What is this I hear Mr Kadarm?...
Have you issued orders for killing raghu in an encounter?
What could I do, suleiman? He was creating so many problems...
Had it been one or two murders, I could've taken care of him... He crossed all limits... even killed the poor parsee. I was nearly sacked.
- Any news of him? - No.
He has gone underground.
We will find him.
Where can he go?
I've set up checkpoints all over Mumbai.
- What if I get him for you?
- He's coming to my house.
At 11 tonight.
But, he will cross check with me at 8 o'clock... if I say yes, he comes.
You will have your money before that... 2 conditions.
One, you will come to my house. With the cash. 8 o'clock...
Done.
You have my word.
Done.
Done.
He's coming. At eight.
The Commissioner's office.
- Put the Commissioner on.
Your Dad! Home Minister Kadarm.
Tell him that.
Kadarm speaking.
Listen, raghu is going over to suleiman Badshah's house... - Know him... the peacemaker? - The one who lives in Kanjur?
Yes. He's the one. Raghu will go there at 11 tonight.
Make sure you post plain clothes men.
By ten tonight.
Raghu will be in police custody by tonight.
What for? Looking for a hike in the budget for jails?
Or are you minding the budget for bullets?
Bloody righteous serfs in uniform! Pump him dry. After he's dead, make doubly sure.
Custody, he says...
And the public think the police are monsters!
Go downstairs.
What are you staring at? I told you to go down.
Suleiman, you take good care of me...
- Wont you count it? - Have I ever counted? I'm giving you 100,000 more...
- why?
- Because I will break my promise.
Suleiman, now what can I do? I cant keep him alive, can I?...
To save my ministry, I have to kill him...
I have to kill him, right?...
I'm the one who introduced you to raghu. Forgotten that?
Come on, suleiman.
No point being righteous...
He has become a pain in the neck. What could I do? Kadarm, you're scum!
Between a snake and you, I'll kill you first... if you want to survive these times, you have to be a snake... if you kill raghu, who will do your dirty work for you?...
- or are you giving it all up? - Don't talk like a fool, suleiman...
These days, there.s this name coming up in the papers... what's his name? ...what's the name?
Anwar! Useful fellow.
Fix a meeting with him.
He will make millions If he teams up with me.
Like the millions I have made.
Stay where you are, pimp...
You've made arrangements for sending me off, have you?...
Mistake! Mistake! Grave mistake!
Men make mistakes, and I'm no angel!...
This suleiman! He's the one who instigates me against you! Look!
He took 2.6 million from me for turning you in.
Son...
Call me son, and your brains will be lying on the table!... sure! I wont. If you insist...
Look... come with me to the police station.
I will get you out in 1 month. I swear it! By my kids!
You don't trust me?
Then stick your gun in my head and take me with you.
Oh, and I have to give you your 30 million...
Liar!
You're a liar.
All your life you've told lies to trap people.
I know you will kill me. Because now you have Anwar.
That done, you will also kill Anwar.
Then someone else... then someone else... You are the worst criminals. You create criminals.
You're rotten to the core.
And the one after you will do just this.
Don't kill me!
I beg of you! - Bend and I break your head. - All right, I wont...
Now that you look in the face of your death, you've lost your nerve...
Can you bring shorty back to life?
Tell me. Can you? Say it!
Why are you wasting your time? I will kill him if you wont. No suleiman, I will kill this one...
Don't worry for me. Just get out of here!
This way... run!
Mom!
Open the door!
Raghu, what's the matter?...
The police are going to kill me!
They killed shorty!... shorty is gone!
There... Bandya's men are going to shoot through the window...
I killed the three Bandya brothers.
Mom, shut the window!... shut the window!
Raghu, what are you doing?...
- sonu, where's Rohit?
- He's sleeping...
Let him sleep in peace.
I killed the Bandyas. Are the windows shut?
Shut the windows! They will kill my son!
My son is going to die! Shut up! Silent now.
Nothing is going to happen to you. Come with me.
- No! - Come outside.
- The police are out there. - I'm with you. Come.
My wife is nice, isn't she, Mom?... she's nice, isn't she?... sonu, go upstairs.
Go, be with my son... when he turns 18, you must take good care of him...
I have you with me now, Mom... sonu, go to Rohit...
- sit here, son.
- You too, Mom... - Yes, I will sit too. - The police will kill me!...
- You're with me, Mom?...
Yes, now what's the matter with you?...
Can I just have a little to drink ...just a little?
I haven't had a drink in 3 days!
- What happened? - Look! Over there!
- What? - Pervez's wife!
She spits in my face! Every day!
- Look at her! - Look at me. I'm here with you.
- She's there!
- There's no one over there.
Mom, can I get some cocaine?...
Expensive, isn't it?... Take this. Sell it!
Take it. It's worth 200,000.
Sell it, Mom!...
if nothing else, just give me a drink of kerosene!...
Give me my release, Mom!... sell it!
This is what you call a gun... Worth 2 big ones... You know how much that is?
Two hundred thousand!...
This is the magazine; You slide it in here... like this...
Give me my release, Mom!...
This is the trigger...
wind your finger around it... and point it at the mark... squeeze the trigger... and the game is over!...
I haven't killed him! I just gave him his release!
I haven't killed him. Really.
I haven't killed him! He died a long time ago. The life ebbed out today.
I didn't kill my son... I really didn't kill him!
I didn't kill him! I'm his mother!
You're a mother too! I have not killed my son! I haven't!
Your father had the right to say that he took to crime... because he was wronged.
But there are thousands who are wronged this way. Not everyone takes to crime. I'm not much educated.
My mom took me to my grandmother's home and told her to take care of me. They treated me like a maid. So then I decided to run away from my home at the age of eleven,
"Are you coming for home?" and I would just tell them my story. After that I started to work with them at the New Delhi railway station. I am a ragpicker there, I used to collect water bottles and refill them to sell for Rs.5 in general train compartments (bogies)
After 6 months, I didn't have any income because every platform had a villain and they would take all my money. Then I decided to go find some other work, I ran away because I wanted to travel a lot.
After that in 2008 I participated in a worldwide competition, which someone suggested to me as they were looking for young photographers. (As shown) I participated and sent these 6-7 pictures in this worldwide competition. They chose me, I got selected in the top 10.
After that I went to the U.S.A for 6 months, where I started studying in ICP (International Center of Photography) They also gave me an opportunity to take photographs of the re-construction of the World Trade Center every week, one day for 2 hours. They gave me permission to click photographs.
"Duke of Edinburgh" award and I am a gold award holder. They e-mailed me an invite to London and on the first day I went inside the Buckingham Palace and had lunch with Prince Edward.
After that in 2010 in Bahrain, there was an Indian Ladies Association they invited me and my exhibition there and awarded me. After coming back I was still, working on my project "Apna Ghar", and apna ghar... Before this exhibition, some of the pictures were selected were selected for The White Chapel gallery in London and some photographs were displayed in Switzerlands photo museum.
So, what I'm going to do is just give you the latest episode of India's -- maybe the world's -- longest running soap opera, which is cricket. And may it run forever, because it gives people like me a living. It's got everything that you'd want a normal soap opera to want:
(Laughter) Another half an hour after 12 days. There were two Sundays in between.
(Laughter) The Mahabharata was like that as well, wasn't it? You fought by day, then it was sunset, so everyone went back home.
(Laughter) You could play it on the banks of the Ganges -- that's as clean as the Ganges has been for a long time. Or you could play many games in one small patch of land, even if you didn't know which game you were actually in.
(Laughter) As you can see, you can play anywhere. But slowly the game moved on, you know, finally.
1983 was when we won the World Cup.
1991,'92, we found a finance minister and a prime minister willing to let the world look at India, rather than be this great country of intrigue and mystery in this closed country. And so we allowed multinationals into India. We cut customs duties, we reduced import duties, and we got all the multinationals coming in, with multinational budgets, who looked at per-capita income and got very excited about the possibilities in India, and were looking for a vehicle to reach every Indian.
(Laughter) And so, India had to go and play the T20 World Cup, you see. India didn't want to play the T20 World Cup.
(Crowd cheering) The Pakistani batsman trying to clear the fielder. Announcer:
(Cheering) India, T20 champions. But what a game we had, M. S. Dhoni got it right in the air, but Misbah-ul-Haq, what a player.
(Laughter) If he had bowled fast, the ball would have gone where it was meant to go, but it didn't go. And we suddenly discovered that we could be good at this game.
(Laughter) And so England invented T20 cricket, and allowed India to hijack it. It was not like reengineering that we do in medicine, we just took it straight away, as is.
An opening ceremony to match every other. This was an India that was buying Corvettes. This was an India that was buying Jaguar.
(Laughter) The new owners of Indian cricket were not the old princes. They were not bureaucrats who were forced into sport because they didn't actually love it; these were people who ran serious companies.
I mean the IPL had 2.3 billion dollars before a ball was bowled, 1.6 billion dollars for television revenue over 10 years, and another 70 million dollars plus from all these franchises that were putting in money. And then they had to appeal to their cities, but they had to do it like the West, right? Because we are setting up leagues.
Of course, a lot of people said, "Maybe they dance better than they play." (Laughter) But that's all right.
And then of course there was Shah Rukh playing the Kolkata crowd. We'd all seen matches in Kolkata, but we'd never seen anything like this: Shah Rukh, with the Bengali song, getting the audiences all worked up for Kolkata -- not for India, but for Kolkata.
An Indian film star hugging a Pakistani cricketer because they'd won in Kolkata. Can you imagine? And do you know what the Pakistani cricketer said?
"Players are being bought and sold? Are they grain? Are they cattle?"
Going at 1,500,000 dollars. Chennai. Shane Warne sold for 450,000 dollars.
"For four weeks, I'm earning more than Frank Lampard and Steven Gerrard, and I'm earning more than the footballers, wow." And where was he earning it from? From a little club in India.
So, at 2.3 billion dollars before the first ball was bowled. What India was doing, though, was benchmarking itself against the best in the world, and it became a huge brand. Lalit Modi was on the cover of Business Today.
Right so, finally, an English game that India usurped a little bit, but T20 is going to be the next missionary in the world. If you want to take the game around the world, it's got to be the shortest form of the game. You can't take a timeless test to China and sit through 14 days with no result in the end, or you can't take it all over the world.
Rewrite 5 plus 5 plus 5 plus 5 plus 5 plus 5 plus 5 as a multiplication expression. And then they want us to write the expression three times using different ways to write multiplication. So let's do the first part.
5 times 7. Same thing. You could write them in parentheses.
10 plus 5 is 15, plus 5 is 20, plus 5 is 25, plus 5 is 30, plus 5 is 35. So all of these evaluate to 35, just so you see that they're the same thing. These are all equivalent to 35.
They didn't ask us to do it, but I thought I would point it out to you.
7 five times would look like this:
7 plus 7 plus 7 plus 7 plus 7, right? I have 7 five times. I added it to itself five different times.
Experiences
Some of us have had tremendous experiences. Of biblical magnitude. But they pass.
Perhaps, unconsciously, or we have not yet understood, or recognized, that perhaps, is the mind that keeps looking for experience, and if we could get an experience like that one, and we could stretch it out, eternally...
'I'd be okay with that!' [laughter]
Today I have just one request. Please don't tell me I'm normal. Now I'd like to introduce you to my brothers.
(the aid worker pernille ironside) [Applause]
[Anderson Cooper] Thanks. You have the coolest name, by the way, yeah.
[Pernille Ironside] So one of the groups you just mentioned earlier on, the CNDP [Congrès national pour la défense du peuple], I was part of a humanitarian group that met with him and its commanders for the first time in 2007, in order to negotiate the release of children.
And kids can be saved, they can be brought back and the work could be done? [Applause] [Ironside]
[Ironside] You know, they all have, like any of our children here, they all have hopes and dreams and they have the capacity to overcome the violence that they have been exposed to and forced to commit. And I've seen children make that transformation through the programs that I've helped deliver with my colleagues.
And I'd really like to emphasize that it's those colleagues who are, day in, day out, the Congolese and other national workers, who are really the unsung heroes. [Applause] (I Was Here - World Humanitarian Day August 19 - whd-iwashere.org)
The attachment-abhorrence that occurs for people after falling for talk that is beneficial or harmful regarding them A well-wisher (hitechu) and an enemy (vervi) Hitechu is someone who... (for instance) if your daughter made a mistake, then I would come directly to you
Give me the strength to do a samayik with pure applied awareness of the Self (shuddha upyog), All those [individuals] that have I have come across in my worldly interactions, All those [individuals] that I have met due to work related matters
Would it be the total number of Web users? Well, for an Android game, they're not on the Web. They might hear about it on the Web, but that's not really gonna help you understand the served available market.
If you've practiced and hopefully, memorized your multiplication tables, you'll now find out that you're prepared to do most any multiplication problem. You just have to understand, I guess for lack of a better word, the system of how to do it.
Let's do sixteen times nine.
Sixteen times nine. And you immediately might say, Sal, I haven't memorized my sixteen times tables, there's no way I'm going to be able to do that problem.
So nine times six is fifty-four. You know that from your multiplication tables. And so what you do is you write fifty-four, but you only write the four down here in the ones place, and you carry the five.
Nine times one. Well, that's straightforward.
Nine times one is equal to nine.
Anything times one is equal to itself. But we have this five sitting up here, so nine times one, we have to add that five. So we have to add that plus five.
Fourteen. And there you have it.
Sixteen times nine is one hundred forty-four. And if you remembered your times tables up to twelve you also realize that's twelve times twelve. But just knowing only these two pieces of information, we were able to solve a harder problem.
Ten plus six. This is sixteen. And I can rewrite nine, well, I'm just going to write nine as nine.
Nine times six is equal to fifty-four. But instead of writing fifty-four, I'm going to write that's equal to fifty plus four.
Nine times six is equal to fifty plus four. Well, this is my ones column right here. Let me make a little dotted line.
Nine times ten. Well, you've memorized this. And anything times ten is just that anything with a zero.
What's ninety plus fifty? It is one hundred forty.
So nine times ten is ninety, plus fifty is one hundred forty. And we could rewrite one hundred forty as one hundred plus forty just to be consistent. So what we'll do is we'll put the forty down here, and then we carry the one hundred, but the one hundred really doesn't go anywhere.
Fifty-five times eight. Same exercise. First, you start with the eight.
Eight times five. Let me write it down.
Eight times five we know is forty.
So eight times five, you write the zero down here. It's zero plus forty. And then you say eight times five again.
Eight times seven.
Eight times seven is fifty-six. Let me write it-- this is a different problem now. So eight times seven is equal to fifty-six.
Seven times seven is forty-nine.
Seven times seven is equal to forty-nine. But we have to add this five up here, so you add this five. What's forty-nine plus five?
Five hundred forty-six. Ten minutes ago, you probably never thought that you could figure out the seventy-eight multiplication tables, but you see it's a pretty straightforward process. Let's do a bunch more.
What's three times nine?
Three times nine is equal to twenty-seven.
Put the seven in the ones place.
Put the two up here in the tens place, because it's twenty plus seven. Two tens is twenty. Plus seven is twenty-seven.
Three times eight is equal to twenty-four. But I have this two sitting up here so I'm going to have to add a two. So I get twenty-six.
Three times eight is twenty-four. Plus two is twenty-six.
Two hundred sixty-seven. Now I'm going to do another one, but I'm going to up the stakes a little bit. Just when you thought you were getting comfortable with this,
So what's six times nine? Let me write it here.
Six times nine. We saw this show before. This is fifty-four.
So six times three is eighteen, plus five is twenty-three. Just to be clear, we didn't multiply six times three and add five. We actually, if you looked at where we are in our place on the problem, this is actually a thirty.
So what's nine times two? And I won't do this side math over here. I think you're getting the pattern.
What's nine times two?
Nine times two is eighteen.
Eighteen. Then we do nine times six.
Nine times six is fifty-four. And fifty-four plus one is fifty-five.
Fifty-five. What's nine times three?
Nine times three is twenty-seven-- if we have that memorized. And then twenty-seven plus five is thirty-two. Let me switch colors.
Thirty-two. And then you have nine times seven. That's sixty-three, but we have this three hanging out there.
Welcome back. In the last presentation, I showed you how to essentially reverse the chain rule when you're doing an integral. And you could also do this by integral, it's called integration by substitution.
Right? u is equal to sine of x, right? u is sine of x. Well, what's the derivative of u? du, dx.
Well, we know what du dx is, right? du of dx is equal to cosine of x. We memorized that, and maybe in a future presentation I'll actually prove it to you. So what we can now do is substitute these 2 things into this integral.
Let's take the integral of 2x plus 3 times x squared plus 3x plus 15 to the fifth power dx. That looks complicated to you, doesn't it? Well, just like we said, this is a pattern, like we saw in the previous examples.
So this is du dx, right? du dx times u to the minus 3 dx. And I know what you're thinking, Sal. Well, du dx is e to the x. u is also e to the x.
One definition of NP says, that a problem is in NP, if it has a short accepting certificate. An accepting certificate is information that we can use to quickly show that the answer to the decision problem is yes, (if it actually is yes) and here, short means polynomial size and quickly means polynomial time.
To define NP even more formally, we're going to say a problem is an NP if there is a verification in algorithm. This is a basically computer program on A like a subroutine A such that for any input for the problem that is a "yes", there is a certificate C such that the size of C is polynomial in the size of x, and the verification algorithm will say "yes" but for any x that is a no, there is no certificate C that's polynomially sized with respect to x and the verification algorithm says "yes", so for any yes answer to the problem, a verification algorithm will say "yes" for some small certificate; otherwise, it'll say "no" for all small certificates. For the Sudoku example, the verification algorithm is what we describe as something to take the original Sudoku problem with things not filled in and the answer is printed in the back of the magazine where the answer filled in, and it checks to see whether this is the actually a solution to that.
If it is, then it says "yes" and if it's not, it says "no". Now this is going to fit the NP definition that we've got here because for any Sudoku problem that is solvable, there is some grid that we solve it and we can show what that grid looks like, but for any problem that it's not solvable, there is no way that we can fill in this grid with numbers. So that the verification algorithm will say that it's okay.
Is P contained within or possibly equal to NP? So one possibility here is, I don't know, and if I knew that, I'd win a Fields Metal!, meaning sort of the equivalent of the Math Nobel Prize because this is a big important open question. The other choice is no, P is not contained within NP because if the problem is NP, it means it's decidable in polynomial time and we don't need any kind of certificate and so, it's not an NP and then finally the opposite of that is, yes if it can be decided in polynomial time, no certificate is needed.
so Michele Thompson she has been diagnosed with something known as persistent sexual arousal syndrome, that sounds devastating right well she has up to three hundred orgasms a day alright okay so first we start off with persistent sexual arousal syndrome and that sounds pretty good right? three hundred orgasms yeah it became a really really serious problem for her it effected her relationships a lot of men couldn't keep up with her, I would imagine so so you know she would date guys for a couple months and they would you know get super tired of her, literally and they would leave her, so she thought she was never going to find her knight in shining armor yeah hold up before we get to him she had to leave a job at a factory because the vibrations of a machine sent her into an orgasmic epileptic fit you know she's like wha ha ha ha ha wha right and they're like hey hey just bring it down for a second I mean three hundred a day do you have any idea how much that is no that's insane that's insanity by the way she was working sorry she was working at a biscuit factory so you better get it right, biscuit factory aka cookie factory but um so yeah the machines out in the factory were setting her off man she's sensitive alright so we get to the man riding in for the rescue right his name is Andrew Carr he's a thirty two year old and they've been dating for the past six months she says that they have sex up to ten times a day and that he's doing a great job at um playing into her sexual arousal syndrome gez'um lord mercy ten times a day I didn't think anyone else was doing that, that's not even, I don't even, look, that kind of makes me think the story might be untrue, why is that? what kind of guy can have sex ten times a day? that's like physically impossible. yeah, there's something fishy going on here. because I mean, she's probably embellishing her sex life with him, I don't know but look but on the other hand, she did get, the other guys didn't make it right. and this guy did make it so obviously something's working right so she's happy with him maybe it's not ten maybe it's eight maybe it's four or maybe it's five I don't know four sounds superhuman but maybe he's a super generous guy and they're not only having coital relations maybe he's also you know giving her a little licky lick that's the first time we've ever come up with that I've hear of sippy sip but licky lick okay that's what the direction you decided to go with this? alright what you could of done is he's helping a sister out yes, in a couple of different ways and my guess is you're exactly right he's probably going downtown you know a little this a little that little this you know he's mixing it up right giving her a little boom boom pow here and there a little spinning the records as it were. so uh but they had a video with this which you know is probably copyrighted so you know I don't want to get into it but that dude the whole time she's talking about how many orgasms he's given her he's got the biggest shit eating grin you've ever seen in your life he's like okay and i'm like dude I don't know that I'm bragging you know yeah at the same time she's getting orgasms at a cookie factory yeah I mean that's what I'm talking about I mean a biscuit sends her into a canipsion right so you're like you know what I'm saying while on the other hand if the brother's actually putting out ten times a day that is pretty impressive so I'm split on this story but it reminded me of another story when i was in a brothel obviously, in turkey, in turkey the turkey brothel? yeah, you remember this story so I'm a kid and a friend of mine, kid teenagers right friend of mine takes me and another friend of mine from the states, the states that's what he called it uh to a turkish brothel uh the least sexually appealing place in the world, okay and it was perfect because you go there and you go oh no I'm done with brothels, not interested, right and one, there's one disaster after another okay it's like Amsterdamn but the road is closed off and you walk down the road and you see the women in the houses right and it's like oh no, oh no please please right, and so guy goes into the most disastrous of the options I mean this woman is gigantic she's old and okay, nothing wrong except she's in her lingerie or whatever I guess that was lingerie
Yes, indeed, we could have the 24 down here, but it can't be any deeper than the third level by the same argument that puts the smallest at the top. If you're the third smallest and you're, say, six or seven levels down, what are those numbers that lie above you in the tree. They have to be smaller than you, so you can't have been at least not the unique third smallest.
Welcome to the presentation on averages. Averages is probably a concept that you've already used before, maybe not in a mathematical way. But people will talk in terms of, the average voter wants a politician to do this, or the average student in a class wants to get out early.
1 plus 3 plus 5 plus 20 equals, let's see, 1 plus 3 is 4.
4 plus 5 is 9.
9 plus 20 is 29. And we had 4 numbers; one, two, three, four.
So 4 goes into 29. And it goes, 7, 7, 28. And then we have 10, I didn't have to do that decimal there, oh well.
2, 8, 25.
34 00:01:36,91 --> 00:01:40,88 So 4 goes into 29 7.25 times.
So the average of these four numbers is equal to 7.25.
And we can kind of view this, 7.25, as one way to represent these four numbers without having to list these four numbers. There are other representations you'll learn later on. Like the mode.
8 plus 8 is 16. I just ran eight miles, so I'm a bit tired. And, 4/8, so that's 32.
62 00:03:16,95 --> 00:03:20,75 And now we divide this number by 4.
4 goes into 336.
67 00:03:31,85 --> 00:03:34 33 minus 32 is 1, 16.
So the average is equal to 84. So depending on what school you go to that's either a B or a C. So, so far my average after the first four exams is an 84.
78 00:04:20,31 --> 00:04:23,49 So let's say that x is what I get on the next test.
80 00:04:28,18 --> 00:04:31,99 So now what we can say is, is that the first four exams, I
could either list out the first four exams that I took. Or I already know what the average is. So I know the sum of the first four exams is going to 4 times 84.
97 00:05:22,71 --> 00:05:25,08 So, 5 times 88 is, let's see.
5 times 80 is 400, so it's 440.
440 equals 4 times 84, we just saw that, is 320 plus 16 is 336.
336 plus x is equal to 440. Well, it turns out if you subtract 336 from both sides, you get x is equal to 104. So unless you have a exam that has some bonus problems on it, it's probably impossible for you to get ah an 88 average in the class after just the next exam.
117 00:06:34,67 --> 00:06:39,05 If I said that there are 6 exams in the class, and the
highest score I could get on an exam is 100, what is the highest average I can finish in the class if I were to really study hard and get 100 on the next 2 exams? Well, once again, what we'll want to do is assume we get 100 on the next 2 exams and then take the average. So we'll have to solve all 6 exams.
exams times the 84 average. And this dot is just times. Plus, and there's going to be 2 more exams, right?
6 goes into 5 36. I don't know if if I gave myself enough space. But 6 goes into 53, 8 times.
48.
56.
9 times.
9 times 6 is 54.
6 minus is 20 6 goes into-- so we'll see it's actually 89.333333, goes on forever. So 89.3 repeating. So no matter how hard I try in this class, the best I can do.
So I tried to do a small good thing for my wife. It makes me to stand here, the fame, the money I got out of it. So what I did, I'd gone back to my early marriage days.
(Laughter) So one day she said, openly, I'm not going to support this research. Then other victims, they got into my sisters.
(Applause) Play video one.
(Video) Arunachalam Muruganantham: The thing I saw in my wife's hand, "Why are you using that nasty cloth?" She replied immediately, "I know about napkins, but if I start using napkins, then we have to cut our family milk budget."
That is my idea.
AM: And previously, you need a multimillion investment for machine and all. Now, any rural woman can.
(Video): (Singing) You just think, competing giants, even from Harvard, Oxford, is difficult.
(Applause)
We will now embark on what is probably my least favorite exercise or computation in mathematics-- and I think you'll see why-- where we will invert a 3 by 3 matrix. And in my mind, the only thing less pleasant than inverting a 3 by 3 matrix is inverting a 4 by 4 matrix. It very quickly becomes obvious to you that it's probably better for a computer to do this.
So let's take a look at the types of partners. One of the most interesting concepts is strategic alliances. One of the concepts in start-ups that is important to remember is this idea of the whole product.
So, Intel Inside® was a great example of joint business development. They managed to exchange advertising dollars for a prominent position on the outside of computer manufacturer's boxes. What computer manufacturers got in exchange was gross margin that they never would have gotten in a low-margin business.
say "Hey, this is going to be a 2". But what we'll do in this video is to think How to troubleshoot these problems systematically.
- a coefficient is only one number by multiplying the variable So, some number by multiplying the variable or we can call the coefficient times the variable is equal to something What you want to do is just divide both sides by 7 in this case, or divide both sides by the coefficient
7 times something divided by 7 is only This original thing 7 's if void and 14 divided by 7 is 2 Then your solution is x equals 2
If I have more y 2y's 4 ' s, I'll have 6 y's and this is equal to 18 and now, we know how to do this
If I have 6 times something equal to 18, if we divide the two sides the equacao by 6, do I solve the equacao then divide the left by 6, and divide the so I figur by law 6
and we then y equals 3 and you can try This and ' and ' cool about a equacao You can always check if you got the right answer
2 times 3, this and ' equal to 6 and then 4 times 3 and ' equal to 12 6 more ' equal to 12 and 18 soon this works
On face value, the next type of partnership is the most unlikely. It's when competitors get together in programs to do something jointly for their industry, for example, tradeshows, industry associations, etc. It turns out the automobile industry action group has 900 members of competitors who also to vie to sell the same products to the auto industry.
In October 2010, the Justice League of America will be teaming up with The 99. Icons like Batman, Superman, Wonder Woman and their colleagues will be teaming up with icons Jabbar, Noora,
As fascism took over Europe in the 1930s, an unlikely reaction came out of North America. As Christian iconography got changed, and swastikas were created out of crucifixes, Batman and Superman were created by Jewish young men in the United States and Canada, also going back to the Bible.
This is the kind of thinking that went into creating The 99. The 99 references the 99 attributes of Allah in the Koran, things like generosity and mercy and foresight and wisdom and dozens of others that no two people in the world would disagree about. It doesn't matter what your religion is; even if you're an atheist, you don't raise your kid telling him, you know,
"So when's the article coming out?" He said, "Naif, Islam and cartoon? That's not timely.
Jabbar: Dana, I can't see where to grab hold. I need more light.
Now, tell me which way to go. Dana: That way.
Alarm: Threat imminent. Jabbar:
Jabbar: We're here to help you. Dr. Razem:
Thank you. (Applause) So "The 99" is technology; it's entertainment; it's design.
"Yes, Rayan, just go away." He left his Scooby Doo in his house. I said, "Go away. I'm working.
"Who's falafel?"
(Laughter) True story. (Laughter)
Just as a quick aside, if you're familiar with matrix multiplication, there is a very nice connection between this little algorithm that we're just working on and matrix multiplication. To appreciate that, the first thing you need to understand is that if we can represent a graph on a set of nodes as a matrix and it's a matrix that consists of all 0s and 1s and if it's a sparse graph, say mostly zeros. But if there's a link between node I and node J, then the corresponding position in the matrix has a number in it, number 1.
I want to describe this next result just because it just shows how weird computational complexity results can be. Let's think about the colorability of planar graphs. In particular, here's a decision problem.
A three coloring of planar graph isn't any easier than three coloring in general graph, it's NP complete. What about coloring a graph with four colors if its a planar graph. Well, remarkably, the problems gotten harder and harder from constant to linear to basically it seems like it requires exponential time, it goes back to constant time, and that's because of the celebrated 4-color map theorem that says that any map can be colored with four colors and in this particular case, any map can be translated into a planar graph and so we know that every planar graph can be colored with four colors.
Let's do some problems. Let's say we had two hundred thirty-five times-- I'm going to use two different colors here, so bear with me a second.
Seven times three is twenty-one, plus the three we just carried is twenty-four.
Seven times two is fourteen, plus the two we just carried. This is sixteen. So we're done with the seven.
Four times two is eight, plus the one we just carried, so that's nine.
And now we just add up everything.
Five plus zero is five, four plus zero is four, six plus four is ten, carry the one, and one plus one plus nine, well, that's eleven. So the answer is eleven thousand forty-five. Let's do another problem.
Eight times seven is fifty-six, plus two is fifty-eight, carry the five.
Eight times eight is sixty-four, plus the five we just carried. That's sixty-nine. We're done with the eight.
Nine times seven is sixty-three, plus the two that we just carried is sixty-five. Carry the six.
Nine times eight is seventy-two, plus the six we just carried. That's seventy-eight. And now we just add again.
Four, eight plus seven is fifteen, one plus nine plus five is fifteen, one plus six plus eight is also fifteen, and one plus seven, that's eight. So the answer, hopefully-- I don't have a calculator in front of me-- is eighty-five thousand five hundred fifty-four, assuming I didn't make any careless mistakes. Let's do one more problem.
Three times three is nine, add the one. That's ten, carry the one. Three times two is six, plus one.
Well, that's seven. And then we've done the-- I think I've made a mistake someplace.
Okay, now we're ready to do the four, or the forty, and since it's a forty, because it's in the tens place, we put a zero right here. We say four times four-- well let's clean up the stuff at the top. I always forget to do that.
Four times two is eight, plus the one, well that's nine.
And now we're done with the four, or the forty, depending on how you want to view it. Now we're ready for the six, or the six hundred. Since it's a six hundred, we put two zeros here, and we just treat it like a six.
Six times three is eighteen, plus two is twenty, carry the two. Six times two is twelve, plus two is fourteen.
And now we add it all up. Two. Six.
Seven plus three is ten. Fourteen, carry the one.
One plus nine is ten.
Carry the one. That's five, that's one. I hope you can see.
In this video i want to clarify two ideas that we talk about on a regular basis but they are really kind of muddled up in our popular language
I just got sent this problem, and it's a pretty meaty problem. A lot harder than what you'd normally find in most textbooks. So I thought it would help us all to work it out.
lefthand side of the equation. Now, this is just a standard quadratic equation, so we can figure out now where the x-values that satisfy this quadratic equation will tell us where our normal line and our parabola intersect. So let's just apply the quadratic equation here.
I can just divide everything by 1/2, so this is minus 1 over 4 x0, I just divided this by 2, plus or minus 1/2, that's just this 1/2 right there, times the square root, let me see what I can simplify out of here. So if I factor out a 4 over x0 squared, then what does my expression become?
1 over the square root of 2 squared is 1/2. Is equal to minus 1 over 2 x0. So let's be careful here.
The conflicts or attachment - abhorrence that happens at home as a result of seva or satsang. Let's do samayik on the interferences that occur in the home because of the apparent reason of satsang. This has now become our major vocation.
All right--so let's do some swapping. So, here's how it works. We start out at the root where the problems is and we say "Okay."
In a web or mobile product, instead of building a physical prototype, you need to have a low fidelity app or website available for customer feedback. What does low fidelity mean? Well that's just kind of my description of you don't need an entire finished website but you should at least have a wireframe.
Write 15:25 as a fraction in simplest form. So 15 to 25 is just a ratio, and we can write it. So they've given us 15 to 25.
3 and 5 don't share any common factors greater than 1, so it is in simplest form. So we've done what they asked. We've written it as a fraction in simplest form.
Alright. So now we know how to parseJSON data. How do we actually retrieve that from our server?
XMLHttpRequest object, and we do this using the new keyword, followed by
XMLHttpRequest with the parentheses. Now, note that case is sensitive here. Next, we need to call the XMLHttpRequest open method.
First, we need to specify the HTTP method to use. In our cases, we're pretty much always going to want to use GET. Second, we specify the URL to call out to.
Much like ranking ranking pain, I want you to think about ranking gains. And so, think about it and make a list of what each gain your products and services create according to its relevance to the customer. This is the big idea--the relevance to the customer because much like in pain, you're going to make your first list thinking you got it.
All the parameterizations we've done so far have been parameterizing a curve using one parameter. What we're going to start doing this video is parameterizing a surface in three dimensions, using two parameters. And we'll start with an example of a torus.
That would be the slice. It would trace out, and we're thinking about not a full doughnut, just the surface of a doughnut. So it would trace out a circle like this.
Khan Academy is most known for its collection of videos, so before I go any further, let me show you a little bit of a montage. (Video) Salman Khan:
"My 12 year-old son has autism, and has had a terrible time with math. We have tried everything, viewed everything, bought everything. We stumbled on your video on decimals, and it got through.
(Laughter) The other thing that happened -- and even at this point, I said, "OK, maybe it's a good supplement.
Then I started getting letters from teachers, and the teachers would write, saying, "We've used your videos to flip the classroom. You've given the lectures, so now what we do --"
And this could happen in every classroom in America tomorrow -- "what I do is I assign the lectures for homework, and what used to be homework, I now have the students doing in the classroom."
"What would you do if you had carte Blanche in a classroom?" I said, "Well, every student would work at their own pace, on something like this, we'd give a dashboard." They said, "This is kind of radical.
Me and the rest of the team were like, "They're never going to want to do this." But literally the next day they were like, "Can you start in two weeks?"
(Laughter) BG: So fifth-grade math is where that's going on right now?
Like that focus graph, a lot of the teachers said, "I have a feeling a lot of the kids are jumping around and not focusing on one topic." So we made that focus diagram.
So we need to figure out what 46 plus 43 is. Let me write it down again and I'll write it like this:
46 plus 43. What we do here is we just first look at the ones place We literally have 6 ones plus 3 ones or you could say 6 and 3, and 6 plus 3 is just 9.
Divide and write the answer as a mixed number. And we have 3/5 divided by 1/2. Now, whenever you're dividing any fractions, you just have to remember that dividing by a fraction is the same thing as multiplying by its reciprocal.
So dividing by 1/2 is the exact same thing as multiplying by 2/1. And we just do this as a straightforward multiplication problem now. 3 times 2 is 6, so our new numerator is 6.
5 goes into 6 one time.
1 times 5 is 5. Subtract. You have a remainder of 1.
This 1 comes from whatever is left over. And now we're done!
3/5 divided by 1/2 is 1 and 1/5. Now, the one thing that's not obvious is why did this work? Why is dividing by 1/2 the same thing as multiplying essentially by 2.
2/1 is the same thing as 2. And to do that, I'll do a little side-- fairly simple-- example, but hopefully, it gets the point across. Let me take four objects.
So that is one group of two and then that is another group of two, how many groups do I have? Well, 4 divided by 2, I have two groups of two, so that is equal to 2. Now, what if I took those same four objects: one, two, three, four.
So dividing by 1/2 is the same thing as multiplying by 2. And you could think about it with other numbers, but hopefully, that gives you a little bit of an intuition.
So Google Search was a very simple multi-sided market--just two sides. There were users, and there were payers. But can the canvas actually work with something more complicated, like in the life sciences?
"Oh, we understand what a value proposition is; it's not like what our technology is--it's what gain and pain we're providing." So simplify protein purification, increase yield, increase throughput, decrease cost. Now we're making a lot more sense, and now, if you look at the customer segments-- oh, now they're actually getting down to very specific groups.
Welcome to the presentation on ratios. Now, I'm going to start just giving you a definition of ratios, and this I got from Wikipedia.
"A ratio is a quantity that denotes the proportional amount of magnitude of one quantity relative to another." So I'm going to tell you from the beginning that I think a ratio is something that's easier to understand than to give a definition for because I don't think that Wikipedia definition is that useful. Let me give you some examples. If there are-- let's say there are-- let me make this pen size is right.
Or you could also look at that as the ratio of boys to girls is five hundred / one hundred, which equals five / one. And this is the typical way that a ratio is written: five hundred:one hundred of boys girls. Now, let me ask you a couple of questions based on that.
Sal Khan lives in California outside of San Francisco
The government is monitoring private phone calls your children and my children's private phone calls and tracking who their associates are.
This June we learned that out private lives are no longer private. The US government is secretly tracking the emails purchases, text messages, location and phone calls of people all over the world. Ed Rooney, Ed?
Government surveillance has gone on for decades, but things got a lot worse in 2001, when the US congress passed the Patriot Act, giving secret FlSA courts more authority to grant surveillance requests on a large scale. Instead of getting a warrant for an individual person suspected of crime the governement could now search a large list of persons. Even those under the no suspicion of criminal activity.
FlSA courts aren't required to disclose what court orders are being approved and supporting evidence isn't needed. Of the 1,789 request for authorization, one was withdrawn by the government. All the other ones were granted
This is the most essential problem. Through these secret courts and secret interpretations of the laws, US government agents can illegally track internet users based on things like keywords,
Words like "marijuana"
Almost any email you send might get your account monitored. This kind of tracking can make you second guess what you say. That's why mass spying is unconstitutional.
Experts on surveillance, privacy and intelligence agree on one thing. The NSA, Presidents Bush and Obama and their secret courts are interpreting multiple laws in a way that most Americans would find shocking. This is allowing the kind of surveillance and collection that the Constitution was not meant to allow.
Pretty straightforward problem, don't you think? Now what if I were to ask you what is the average of the five consecutive numbers? Well now, there's two ways of doing this.
I shouldn't say number -- seven odd integers.
Actually it becomes a much harder problem if it was just seven odd -- well actually, the only thing that could be odd are integers anyway, so you could almost assume it. But the sum of seven odd integers is 217. What is the largest of the integers?
X is the largest of them, right? We can assume that they're odd because apparently the problem will work out so that they're odd. So what is the sum of these seven numbers?
Right.
So 7 goes into 249 -- did I do this addition properly? I want to make sure. 2 plus 4 is 6, 6 plus 6 is 12, 12 plus 8 is 20, 20 plus 10 is 30, 30 plus 12 is 42.
259. So 7 goes into 259 -- let's see, 7 goes into 25 three times, 3 times 7 is 21, 49 -- it goes into it 37 times. So we get x is equal to 37 and we're done.
Now that have a basic understanding of what a ratio is, let's see if we can tackle some more advanced problems. So, I have a classroom. It's got fifty-five students in it. fifty-five students.
In Order to Acquire an Opinion Free Vision for Individuals... When it comes to the opposite person instead of bringing closure and inner satisfaction (samadhan) we tend to have overt insistences (aagraha) when speaking with them we tend to have opinions (abhipraya) when talking with them The other person tends to feel pain (dukh) [due to our interactions]
In whatever activities Whatever actions that have occurred For that person
And the pure Soul is separate, is nirdosh (flawless), and shuddha (pure) [May I] set this drashti (vision) During all actions
Up to this day Wherever I have given such abhiprayas (opinions) May I clean them during this samayik
Alright, now let's try creating our own XML HTTP request. What we'd like to do is requestWeapon.JSON which is the previous JSON code that we parsed. Then, once the response kicks in, we'd like the onLoad function specified to parse it, like we did before, If you're a little confused, more detailed instructions are provided in the comments here.
I'm here to enlist you in helping reshape the story about how humans and other critters get things done. Here is the old story -- we've already heard a little bit about it: biology is war in which only the fiercest survive; businesses and nations succeed only by defeating, destroying and dominating competition; politics is about your side winning at all costs. But I think we can see the very beginnings of a new story beginning to emerge.
50/50, 90/10, whatever that player wants to propose. The second player either accepts the split -- both players are paid and the game is over -- or rejects the split -- neither player is paid and the game is over. Now, the fundamental basis of neoclassical economics would tell you it's irrational to reject a dollar because someone you don't know in another room is going to get 99.
The next step in this funnel is remember we just talked about getting customers and let's talk about keeping customers. This is what I called the you-should-be-so-lucky-to-have-this-problem part of the funnel, and that's how you grow the customers you have. When you're thinking about growing customers, nothing magic.
A retailer in the United States called Sears had a line of tools that they sold to people who made things and their product line always had three types of products--good, better, and best. And what they would try to get you to do is get you into the store looking at the price of the good product but then when you got there, you said-- well, I deserve better and then someday I could aspire to the best.
My life has been an unexpectable, unsusual journey and I keep discovering new things about myself, as I suppose all of you do. When I was young, I used to think that happiness comes from approval, acceptance, applause, material acquisition. But I have learnt that all these tickle my ego, but the feel-good factor is temporary.
>> Now tiled, similar to texture packer, outputs a JSON file that we first need to load into memory. What we would like you to do is to perform a xhr in the load function here to load the tiled JSON data into our game.
>> With this in mind, your next assignment requires you to use the data file you've parsed to render the few images on the screen. You're going to need to fill out the two functions below to properly draw images on the screen. Now, before you get started, let's talk about something real quick.
The drawSprite function needs to fix this. It assumes that it's going to be given a spritename, which represents the name of the loose asset file as well as the position X and position Y on where it wants to render it on the canvas. Since we're just given a spitename, we need to map where that spritename exists inside of the atlases that we've loaded.
Once the drawSprite function figures out what atlas this given sprite is actually in, it can pass that data to drawSpritelnternal, handing off the sprite information, what atlas sheet its coming from, as well as the position X and Y that was given to us from drawSprite. Drawspriteinternal should actually do the heavy lifting of positioning the element, and drawing it to the world, taking advantage of the draw image API that we just covered with all of its new fancy bells and whistle parameters.
What I'd like to show you today is something in the way of an experiment.
Today, thanks to technology, we can share those stories as never before, by email, Facebook, blogs, tweets, on TED.com. The tools of social networking, these are the digital campfires around which the audience gathers to hear our story. We turn facts into similes and metaphors, and even fantasies.
Welcome to the presentation on systems of linear equations. So let's get started and see what it's all about. So let's say I had two equations now.
--but lets just say for sake of argument, that first line all the x's and y's that satisfy 9x minus 4y equals negative 78, let's say it looks something like that. And let's say all of the x's and y's that satisfy that second equation, 4x plus y equals negative 18, let's say that looks something like this. Right?
16 plus 9. 4y minus 4, that just equals 0. So that's plus 0 equals, and then we have minus 72 minus 78.
--x equals minus 6. There we solved the x-coordinate. Now to solve the y-coordinate we can just use either one of these equations up at top.
So they actually intersect someplace around here instead. I drew these, the line probably look something more like that. But that's pretty cool, no?
Now if I were doing this as fast as possible, I'd probably multiply this equation times 7 and it would automatically cancel out. But that's easy way. I'm going to show you that sometimes you might have to multiply both equations-- actually, not in this case.
140 00:07:07,456 --> 00:07:10,71 Hope this one's harder.
I think it will. OK, negative 3x minus 9y is equal to 66. We have minus 7x plus 4y is equal to minus 71.
We asked 50 rights advocates how they turn information into action and we asked what info-activism means to them
Info-activism means having access to technology and being able to use technology to create and disseminate information in a very democratic and participatory way
Giving people information helps them make informed decisions helps them mobilise and motivate their communities and it also means helping to raise hope in circumstances where that's the last thing that you actually feel you have
People who haven't had access to sophisticated tools for communicating and advancing their agenda now have pretty amazing access
We have these amazing tools with the internet and mobile phones to spread messages very quickly And the entertaining messages spread even more quickly
It has to be people centred.
Has to be participatory
And it has to be the strategic use of different communication tools
It's about using new spaces that have opened up because of the internet and even new media as well even cheaper forms of digital technology whether it's video or other platforms such as online publishing And it's about making use of all these new spaces to do you know, to do old fashioned activism engagement creativity interaction mobilisation connecting people participatory accessible inspired sharing co-operation action change 10 tactics for turning information into action a film by
Tactical Technology Collective
Information is power.
It can raise awareness, improve lives uncover corruption and rights abuses and when used effectively within a campaign bring about equality and justice.
Info-activism is what happens when rights advocates use information as their primary asset for driving change.
It is what happens when we turn information into action to address an issue.
Info-activism involves harnessing information and communication tools for positive social change.
Here are ten tactics explained through successful campaigns from around the world that you can use to turn your information into action 10 tactics for turning information into action.
Mobilising people around the issues that matter to them Requires a strong message, clear goals and a good plan.
Video is a powerful tool that can be used to bring people together to take action.
We train communities in making videos and in one of the areas where we train communities they made a film on land rights in a very feudal part of Gujurat and all the videos actually end with a call to action.
So the call to action in this video was to stand up for their rights and ask for the land.
Video is a good tool because I think a lot of communities do not have literacy and access to other forms of technology, for instance the internet.
In that sense I think video is a very good medium to reach out to such communities because you see things happening right in front of your eyes and it really creates a lot of impact.
As a result of this film which was screened in around 25 villages around 700 people took a rally out and went to their local administrative office and filed complaints that they were not being distributed land
Although the application is still under process the fact that 700 people got together and took a rally out was a great thing and it was one of the biggest impacts that we've had.
Online platforms, such as social network websites can be used as virtual meeting spaces for people concerned about a particular need or issue
Rebecca Saabe Saade uses Facebook in her work with lesbian, bisexual and transgender women in Lebanon.
Because facebook is so popular in Lebanon it allows the organisations Rebecca works for to connect with a large number of people struggling with discrimination and social pressures.
But using popular social network sites like Facebook has disadvantages as well.
When I was working with marginalised society it was different because mainly the pressure is social so just by being out it's a problem.
So we had to find a way to use this very popular tool in Lebanon without damaging their security or their anonymity.
So what we did is we started this very lonely profile that doesn't have any friends, that just contains very basic information: the logo, the name of the organisation, the country and what we work on which is lesbians or trans in Lebanon.
The whole point of this profile is not specifically social networking.
It's just to help these women or whoever is looking for support for lesbians in Lebanon to just get to our website. It's linked to our website.
I mean we have profiles in different places but this is the point. The point is to always advertise in a very popular way to get them to our website.
Working with a very marginalised community that I work with we were aware that Facebook is not private at all.
No matter what you try to do it can not be private.
So if we start a group, for example, and a lot of girls join that group, it will be very clear that these girls are lesbians, most probably.
So what we had to do was find a very inventive way of not connecting anyone to us.
The Pink Chaddi campaign in India also revealed pros and cons of using Facebook.
'Chaddi' means 'underwear' in Hindi
The Pink Chaddi campaign was developed as a response to women being attacked by a right wing political group called Sri Ram Sena simply because they were seen drinking in pubs.
The Pink Chaddi group mobilised 16,000 people to join the campaign within just three days and it peaked a few months later with over 50,000 members.
"In a shocking incident of moral policing... hoodlums viciously attacked girls who were at a pub..."
A lot of the images of this attack were broadcast on television across the country and a lot women and other people got very angry at how women were being treated by the Ram Sena.
There was a lot of momentum on the online group, a lot of anger and resentment that had to be translated.
One of the ways it did get translated was the sending of the Pink Chaddis to Pramod Muthalik.
There was a lot of media coverage as well of this act and in response what he has said first was that he would respond by giving pink saris because he wants to cover up our perversion with something decorous like a sari.
The Pink Chaddi campaign has definitely been successful in my opinion because it has allowed for a space in which a conversation has happened between ordinary people and the Hindu right which is not always possible.
It's a non violent response and it's not about beating up people who were involved in the campaign which is very often what happens -- that there is a violent response.
There were various problems with the online activism which made it difficult to translate into an offline mode and one of them was the fact that it was on Facebook.
And Facebook stops you from messaging the people in your group after you hit 5,000 members.
So without realising when we crossed that mark and became 16,000 and 40,000 we realised we could not communicate with anybody who was in the group anymore.
All that could be done was discussion boards and messages on the wall which were not effective enough to communicate with everyone.
Later, the Pink Chaddi campaigners learnt that using Facebook had other disadvantages as well.
The groups online presence was hacked into, defaced and later deleted while offensive messages were sent to the group's creators.
Despite numerous requests on Facebook to re-establish the group months later, no action had been taken.
These examples highlight the need to be alert to both the opportunities and risks involved in using online platforms for activism.
As media recording devices have become smaller and cheaper people have started to record rights abuses, as they happen.
Supporting witnesses to record rights abuses and providing spaces where they can be broadcast is a useful tactic that can be used to highlight rights abuses and have them addressed.
For me the power of video lies in it's ability to convey the visual evidence and the real first hand experience of what it's like to experience, for example, a human rights abuse.
The exciting thing now is people have cell phones which they can use to capture the first person reality that they experienced.
So it's no longer just a select few who get to tell the stories.
Everyone has the potential to be a witness.
Witness, record, broadcast and expose.
This was the tactic used by the Targuist Sniper -- an anonymous video activist in Morocco who filmed police officers taking bribes from motorists.
So he filmed those police in different places in different days of the week doing the same thing.
He filmed about 10 or 15 police agents doing the same abuses in the streets of those villages.
He put that on YouTube: he published the first, second and third videos The videos were seen by hundreds of thousands of users.
They pushed the government to arrest those agents and they pushed the government actually to use the same technique and hide cameras in the street and monitor police agents by using the same technique as was used by the Targuist Sniper.
In a different context in Burma citizens' documentation of state abuses does not appear to have changed the behaviour of its military regime.
However, bloggers have recorded and broadcast what they have witnessed putting a global spotlight on Burma and this has raised awareness about the human rights abuses that are taking place.
Now, in Burma, everything is restricted especially internet, email and online stuff.
But a lot of people in Burma are using blogs.
So they are posting stories, images, whatever they can get.
And then people around the world can see what is actually happening in Burma.
Blogs and cheap digital recording devices were seen as integral to the so-called Saffron Revolution that took place in Burma.
As the Burmese protests about economic hardship and military brutality grew in size and frequency, reports of military violence also increased.
Images of protesting nuns and monks wearing saffron coloured robes were broadcast on the internet and were then picked up by mainstream media across the globe, leading the military regime to temporarily cut all internet and most cellphone services during the peak of activities.
Despite this, as Aung explains, the deployment of simple, cheap cameras was critical for recording what happened while blogs were an invaluable tool for getting news and images distributed to the outside world.
What happened was people saw this thing happening in front of their eyes and they just took a camera and they just shot it.
All the photos, audio, videos that they got they just posted them up on blogs.
That did automatically become a very good success.
But under repressive regimes successful online info-activism does not always easily translate into offline impacts.
In Burma, many bloggers are now paying a high price for their online activism during the Saffron Revolution.
Many have been jailed with sentences sometimes stretching beyond 50 years.
This shows why the consequences of online activities need to be thought through carefully in advance by those involved in uncovering and broadcasting rights abuses.
Victims and survivors of human rights abuses are already vulnerable.
So it's really important when we film them to make sure we don't doubly victimise them.
For us that means making sure that people understand the worst case scenario for who will see the footage.
In a digital era you can't assume that once a piece of footage is out there it won't be copied, placed on YouTube and seen by the perpetrator or the person who is responsible for whatever happened.
We think you should explain the worst case scenario and help people make their own judgement about whether they want to speak out or be seen and then take measures to protect them.
So disguising their identity or voice and taking those steps.
I think one of the biggest challenges now for info-activism is how we encourage thousands of people who are now participating in movements for human rights using video to think about how they understand the importance of consent and how do they understand these issues so they don't doubly victimise people who have experienced human rights abuses.
Mobile recording devices, blogs, videos and online broadcasting channels Are just some of the ways that info-activists can record and expose rights abuses and support actions that will address them.
But as these examples have highlighted, it is essential to carefully consider people's need for anonymity, to protect those who may be vulnerable to further abuses.
To really engage an audience, you need to be creative.
Rather than overwhelm people with words or text there are many ways to visualise an issue.
Animation is one way and it is a medium that also provides a creative license to explore sensitive issues.
I think animation would be particularly good as a info-activism tool in advocacy in a situation where there's an explosive or sensitive political context where you don't necessarily want to handle things in a literal way or in a head-on way when you're dealing with, for example, race or gender sensitivities because you can use animals or objects, for example, in animation rather than real people.
That gives you a license to deal with a lot of things that you can't deal with in conventional film making.
I think the magic of animation appeals to everyone.
Moving inanimate objects or objects you don't expect to move is quite amazing and it's something that excites most people.
I'm currently working on a project in Cairo with a group called The Women and Memory Forum who are re-writing Arabic mythology or folk tales from a feminist perspective
We're producing a three minute animation based on one of those re-writes in order to have different cultural representations of women in the Middle East.
Maps are another way to visualise information.
There is something timeless about maps and this may be why they are a medium that people seem to trust.
During the 2006 Israeli invasion of Lebanon human rights NGO, Samidoun used maps to help people understand what was happening.
We did a couple of maps during the summer of 2006 at the time of the Israeli invasion of Lebanon.
The two main maps, one detailed the daily bombings on Lebanon every day and it was updated daily.
And the second map detailed damages in infrastructure and vital sites.
During that period when we started we didn't really know what we wanted out of collecting that information but we wanted to understand what we were going through.
As we started working and publishing the stuff we had we discovered different uses for it in activism, in organising relief work and in facilitating reconstruction later on.
You don't need to create new maps to embed your messages.
Anyone who tries to look at the Tunisian Presidential Palace using Google maps, is likely to find some unexpected information thanks to the work of Tunisian activists involved with the independent collective blog site, Nawaat.org
There is a very creative experience that we've seen on the Tunisian internet when activists from Nawaat geo-tagged their videos on YouTube.
By geo-tagging I mean giving geographical information or the name of the place of the video you are publishing on YouTube.
By doing that you are making your information, your video available and watchable on the mapping tools of Google.
So what the Tunisian activists did is they geo-tagged all the videos about human rights abuses in Tunisia by putting them around the Tunisian Presidential Palace in Carthage So when you go to Google Earth and you go to the Presidential Palace you will find it surrounded by videos talking about human rights abuses in Tunisia
So you will find two sides of Tunisia. The touristic side of Tunisia about the big history and on the right side information about the recent Tunisia the modern Tunisia of human rights abuse.
Maps and animation are two of many tools that can be used to help people navigate and interpret information in a visual way, that will engage them and embed pictures in their minds that are likely to resonate over time.
It is easy to get lost in the big picture of human rights abuses.
Bringing people's personal stories to the front of your info-activism is one way to make sure people's experiences are not ignored.
We use personal stories in our information activism because as a feminist organisation the personal is political and for us they really demonstrate the real life application of human rights and women's rights.
An example of where we've used digital stories in our work is in a training with two groups of women.
One group of women were survivors of sexual assault because of their sexual orientation.
And another group of women who had survived domestic violence.
We put these stories together on a DVD and we distributed the DVD with a book that gave instructions on how to integrate the stories in a human rights education programme.
So the stories were really meant to provide alternative training materials to people who are trying to do change-making training.
We hope that will also contribute to the information that's out there but assist in understanding and also reduce violence against the groups that we are speaking about and help inform policy that is really addressing the needs of people as they identify them.
This a particular example of how a silenced community can take control over their own words and images and make something not necessarily revealing their identities as well.
They get to choose the voice, the images and also have control over the actual equipment and the computers themselves.
Personal stories can be compiled and distributed in many different ways.
Grassroots video-making can capture people's experiences in a way that will bring about change.
We were working with a group in the Democratic Republic of the Congo where about 5 million people have died as a consequence of the conflict.
One of the biggest problems is the use of child soldiers.
This group was trying to find a way to engage communities to think about why they let their children become child soldiers.
So they thought to produce a video that would open a debate in their community.
They showed it in communities all around the Eastern Congo to start a discussion.
I think that's really important because they thought not only about what the issue was, but they also thought about who their audience was what their goal was and what story they had to tell.
They were successful in starting to get people thinking about that and then they realised their campaign had moved on.
And so they needed a new tactic.
At that time the International Criminal Court was starting to think about its first prosecutions. So they said, 'well how can we influence the criminal court to think about that'
A completely different audience.
So they made a different video which really brought the voices directly of those children who had been forced into the military to show to senior officials at the criminal court.
And they chose a different story.
It wasn't an open story, it was much more of a directed story saying to that audience
'You need to act on this because this is a crime of war... ...a crime against humanity'
For me that's really an illustration about how the power of personal experience at a local level captured by people who are closest to it can be used as a tactic to influence different audiences at different times to really achieve change.
Blogs are renowned for their ability to blur the lines between personal and public dialogue which makes them an effective storytelling tool.
The collaborative blog project, Blank Noise allows people to support an ongoing discussion about sexual harassment in India.
They invite bloggers to talk about their experiences of urban sexual harassment.
But they do in a way where, well in the year that I participated they asked us to talk about it as if we were superheroes.
So it's a very interesting take on urban sexual harassment.
It's not a report, it's not like a sob story, it's kind of wittily put.
So it's a great way of making things readable as well for a different audience.
I think blogs are good tools for info-activism because they lend themselves to storytelling.
Blogs are very personal so it becomes quite easy for individuals to put their perspectives out there.
And it's very easy to use, it's like journaling.
It's a very accessible way of writing and also reading about issues.
The way most blogs work for info-activism and for advocacy is through blog communities.
Blog communities centre around a particular issue and they usually have a time-frame where they write around a particular issue.
Blogs, documentary videos and online stories are three ways that personal stories can be used to ensure that people's experiences reach different audiences and bring about social change.
A good joke can spread far and wide and can be a powerful tool, especially when it is used to criticise or mock power in environments where it is difficult to do that in a direct way.
In Egypt, while activists were trying to mobilise people against the Mubarack's regime we got tonnes of contributions from practically unknown young people on the internet of humorous images that are basically remixing of film posters depicting the face of the President in place of famous villains and thugs and thieves and members of organised crime or whatever to make a statement about the current situation.
In a very short period of time because of the incessant use of humour the whole mystique of power around the President was completely destroyed and he is now perceived as an aging old man who is trapped into this role and being very inefficient about it.
That became like a kind of narrative platform to build an actual movement that is demanding democratic reform and clean elections and so on.
People don't only laugh at good jokes.
Ever been to a karaoke bar with your family or friends?
The Asia Pacific Network of Sex Workers in Thailand use karaoke to raise awareness about serious things using popular songs with lyrics and video clips that are re-focused on sex worker's rights.
It's a clever tactic, which uses popular music to transmit information to sex workers and their allies and to get them thinking about what is wrong with the laws and policies that affect their communities and to push for change.
I use video Karaoke because in Asia people love to sing a song and see the picture Video Karaoke in Asia is really popular.
So it's easy to get people into it.
That's why I got the idea to change the lyrics of a song So it was easy to get a message across about anti sex worker policies and the new trafficking laws.
For sex workers from the Asia Pacific Network Kareoke provides a common language, even when they do not have another language in common.
The group's karaoke videos have been screened across the region at parties, performances and in front of audiences of thousands such as at an international HlV/AlDS conference.
One video received nearly 10,000 views online on YouTube and Blip.tv
A different example of how humour can be used came in the form of a birthday gift to Belarus's President, Alexander Lukashenko after he complained publicly that the internet was too anarchic and announced plans to tighten content restrictions.
Activists responded with an online campaign that sought to mock what they saw to be propagandising government-controlled media.
Humour is the first step to break taboos and to break fears.
So by making people laugh about dangerous stuff like dictatorship, repression, censorship is a first weapon against those fears, actually
There is a very funny campaign launched in Belarusia, a few years ago.
It's called 'Give Luchenko his net' Because Luchenko made statements accusing the internet of playing against the government of Belarus saying 'their is a lot of untrue content there'.
So the Belarusian activists made a clone of YouTube and Live Journal And published their stuff, very funny videos and humorous cartoons about President Luchenko
This kind of use of tools that are easily identifiable by internet users, but switching the content to something political and shaping it in a humourous pattern that makes fun and it makes political accounting interesting.
Making people laugh can be a highly effective way of breaking down barriers that prevent positive social change.
Websites, karaoke video clips and film posters are just three ways to convey a serious message in a light, yet effective way.
Sometimes an overlooked part of info-activism work is the value of maintaining and sustaining healthy networks.
Networks are power in the digital age and exploiting them fully requires planning and time.
All the non-profit work and campaigning is basically about people.
And when you translate it into technical language
People are contacts.
Not only people but organisations, groups, relationships in between them.
All of this is information that you can build on that you can use to engage your audiences and you can use to engage your targets.
I am personally involved in a project called CiviCRM which is a free and open source software built especially for non-profit organisations and advocacy groups.
It has been built with a lot of feedback from all those groups so in my personal opinion it's basically an excellent tool for managing contact information.
FrontlineSMS is a different kind of software that also supports targeted, network communication this time, specifically using SMS.
Well managing contacts is obviously important from an organisational point of view but speaking from the perspective of the someone you are communicating with the last thing they want to be receiving is messages or information that they are not concerned about, that does not interest them, is not relevant to them.
So if you're running multiple campaigns clearly you don't want to be sending the wrong groups of people the wrong messages.
It may be necessary to send a message just to a group of women in a particular area or maybe to human rights activists working in a particular region.
If you're not categorising people in the right way then you're going to start blasting people with things they don't want.
Not only does that affect the effectiveness of your project or your campaign but it also upsets people and it can be very counter-productive.
A good example of how FrontlineSMS is being used to help send targeted messages and communicate with targeted groups was during the reconstruction efforts after the Asian Tsunami where a project being run by Mercy Corps was looking to have conversations and send specific information to a different number of groups.
So using FrontlineSMS they were able to group people into different categories and these people included farmers, who might want to know the coffee prices in different markets, Government Ministers who wanted summary information on the different market prices being charged in different areas other people wanted weather forecasts.
Using FrontlineSMS and using the grouping facility and functionality within the software they were able to put people into multiple groups depending on what information they wanted to receive and then they could target those people with an SMS providing them with that market price, or that weather report or whatever the information might be.
If you want to manage your contact information in your info-activism work you need to be systematic you need to try to integrate information collection on almost all the levels
But after some time you will see the incredible effects of seeing different connections, seeing patterns.
Basically it's like getting a very powerful tool to find out about what's happening around you and giving you a powerful tool to achieve your goals.
Databases, client relationship management systems and bulk text messaging software are three tools you can use to manage your contacts and to sustain healthy and productive relationships with the people who want to support you.
Sometimes issues are very complicated.
They may involve issues that have been evolving for a long time or they may be connected with many events and many different people.
To enable an issue to be understood you may need to find out what information exists and whether you have a legal right to access it.
Every year most of us pay our taxes to the government and every few years we elect the representatives who will run that government and therefore we're handing over power and money and we have a right to know how that money is spent and how that power is exercised.
In over 82 countries around the world access to information or freedom of information laws give everyone a right to ask a question and get an answer from their government.
The international standards are very clear that access to information procedures should be simple, fast and free.
Generally they are.
In the majority of countries filing a request for information is free.
So we have many examples from around the world where people have asked the government a question got information and used that in public debate to change the way things are done.
Farmsubsidy.org is an initiative that lobbies for access to information about government farm subsidies across the European Union.
It aims to ensure that journalists and civil society are able to scrutinise how the billions of euros of funding allocated for farm subsidies is spent.
Within our campaign at farmsubsidy.org when we're successful we're almost faced with an avalanche of information.
Deciding which information to draw the attention of the media to is very difficult
If you've got an enormous data set and you're trying to find out ways to present it to people one really good way of doing that is to make it relevant to them in their locality, in the area where they live.
A great way of doing that is to use a map to plot the data out on Google Maps, it's quite easy to do that now, the technology is free we've done that with Sweden because we got excellent coordinate information for Sweden and so we were able to present seven years worth of farm subsidy payments in Sweden on a single Google map so people could zoom right in to find out where the money goes in their area and that really makes it relevant to them -- much better than looking at a long list that goes page after page of boring text.
But getting access to government information is not always easy whether a freedom of information law exists or not.
It took me three years to get the data on the UK farm subsidy recipients and I'm not quite finished in fact with my request.
So you have to be prepared for a long fight and to not take no for an answer and to use any tactic you've got whether it's your legal rights or whether it's political pressure that you can apply through anyone you might know working in the area or maybe even through the media
You need to just build up the pressure using your rights as a citizen.
In another example, technologists and rights advocates obtained information from multiple sources including government and non government agencies.
The information came in many different forms and so the challenge lay in making it meaningful to a global audience who could then take action.
A project I was involved with was the featured layers on the Darfur Crisis in Goggle Earth.
We were a team of about a dozen people assembled by the United States Holocaust Museum.
They wanted to, in a very engaging way raise awareness of what was happening in Darfur.
We really pushed the boundaries of what could be done in Google Earth.
We had a great amount of information -- spreadsheets, photos, videos plus the base layers in Google Earth themselves which were recently updated satellite images often showing villages that had been destroyed in Darfur.
We spent about six months working with that data to really pay proper respect to the situation there so that we could convey a powerful message.
It got great coverage by Google and in the media and thousands, maybe even hundreds of thousands of people have seen those layers and it's greatly raised awareness of the issues there.
We also provided direct means for people to get involved in the campaign.
So from the layers there were links to sign petitions and to get even more deeply involved in the cause.
It's not always an easy task exercising your right to information and then finding the right ways to present dense information to engage the public.
But it is an important tactic in Info-activism.
If you can persist you may be rewarded with significant leaps forward for your cause.
Not so long ago, real time collaboration between large numbers of people was difficult if you weren't physically gathered in the same space.
New technologies have changed this.
We are now seeing innovative examples such as what is sometimes called swarming.
Swarming is what happens when people's experiences and knowledge are pulled together to create a combined effect far greater than their individual acts.
As the 2008 Mumbai attacks unfolded, a swarm was created using Twitter. A microblogging service that allows people to send and read each others personal updates via the internet and mobile phones.
When the Mumbai terror attacks were happening there were a lot of us within the vicinity and we started pouring out our emotions and talking about what was going on and what we were seeing on television into Twitter.
We were feeling like 'what do we do?' and we were feeling alone in our homes because we weren't allowed to get out and it allowed us to feel less alone, less angry as a group and we able to actually network with people on the ground to bring out information that was required.
For instance, we had people going to hospitals and collecting lists of injured and dead which wasn't published anywhere on the web and they were faxed to us and then we quickly put them up as links on Twitter to a blog that was supporting this.
In other cases it was about getting the right kind of blood to the hospital that required that kind of blood.
So its about spontaneous mobilisation of a community that already exists through the multiples nodes and hubs that you have as you leave your footprints on the web.
The other thing that is really sort of almost magic about microblogging is the aggregation of these things and the amplification of these things because it is a broadcast mechanism.
So that served in getting a lot of interest from mainstream media which fed back into how effective the mobilisation could be around awareness of what was going on.
As the Mumbai terror attacks showed, mobile phones have become vital tools during crises.
In Madagascar, mobiles were used with computer software to enable citizens to report what was happening when anti-government protests turned violent.
One software program, FrontlineSMS allowed text messages to be sent and received by large numbers of subscribers in Madagascar while Ushahidi allowed subscribers messages to show on a map.
In 2009, during the troubles in Madagascar where I believe some demonstrators were shot by the army there was clearly an opportunity there to collect information and news and voices of people on the ground who were experiencing the troubles, who were involved in the demonstrations and who were impacted by what was going on.
Using technologies you can combine the collective voice of people so people can SMS in information, they can send in emails, they can complete online forms.
You can then aggregate that information with the news coming in from the mainstream and then bringing all that together you get a much better picture of what's happening on the ground.
Ushahidi, the crowd sourcing platform, which used FrontlineSMS to allow people to text a number and then contribute to the news through their mobile phones so people could go to the internet and send emails or they could go onto a website and complete a form.
People generally prefer, due to convenience and speed, sending an SMS and FrontlineSMS was used to collect those messages which was then posted to the Ushahidi site and from that point they were aggregated with the other reports coming in including information from the mainstream media and then placed on a map and it gave a very good idea of where the hotspots of the trouble were and it gave a much broader view of what was happening in the country than otherwise would have been given.
As these examples illustrate, mobile phones, when connected with online platforms can be a powerful way to combine experiences and knowledge to report events comprehensively as they unfold.
Technology that listens is technology that responds to individual information needs.
One example is Infonet's budget tracking platform which allows people to send free SMS enquiries about the allocation of funding for development projects in their local area.
Citizens can then contact social watch groups to assess if funds have been spent in the way that was intended.
The context here is that we developed a system that uses short code SMSs and we get people sending in queries about the amounts of money that have been allocated for projects at a local level.
It's a two way process because they query the system and at the same time, they feed the system with content.
Infonet's budget tracking platform has led to a number of discoveries of misused funds.
By leaking these findings to government and mainstream media
Infonet has been able to ensure that corruption has been addressed and citizen efforts have been rewarded with action.
Recent developments have greatly increased the ways technology can listen and respond to people's needs.
The phone used to be something that was controlled by the telecommunications monopolies and over the last few years, there's been a whole renaissance in telephony technology that's built around voiceover IP.
You can now run your own phone company on free software.
What that means is you can do all of the creative call centre and interactive voice menus and that kind of stuff on your own phone system or on your own home computer so many activist groups will now set up a call-in line.
Using their own phone system, the Kubatana Trust of Zimbabwe developed a platform that ensured citizens were informed via an SMS about where they could vote in government elections.
In Zimbabwe, we've had many elections over the last seven or so years
One of the government's tactics was to make it difficult for people to work out where to vote and where to register to vote.
But one of the things that we did was to help people find out where to vote by cooperating with another organisation that had managed eventually to get the voters' roll into a database format.
We got people to send us their national registration IDs using SMS. We compared those IDs against this database and then we SMSed back to the people where they could vote.
It was a very interesting campaign and a lot of people took advantage of it.
While thousands of people used this system developed by the Kubatana Trust the experience showed that lack of literacy and language differences continued to limit people's use of SMS services.
To address this, Kubatana are now developing 'Freedom Fone'. A system that uses voice recognition rather than text to provide people with information.
The Freedom Fone project is being built out so that each group can take a copy of this software and run it on their own system and simply provide the menus of what kind of information they are going to access and provide.
Freedom Fone registers that they called and the phone system calls them back so the organisation is able to cover all the costs.
There is a tool that has been overlooked I think by the development sector and that's the area of interactive voice response.
We believe that if we can make this an easier device to use by non-profits that we will see people reach out to their communities using dial-up information services which would become almost the poor person's equivalent of the internet, being able to dial up for information when you need it.
Designing and using technologies that can listen to people's needs and respond quickly can be a good way to quickly address immense gaps in information and improve information flows.
When corruption and right's abuses are being committed by those with the most power such as governments, multinational companies, police or the military It is sometimes necessary to investigate and expose what is going on.
Although there was widespread knowledge of police brutality in Egypt it was an issue the mainstream media seemed unwilling to report on.
To help affected citizen's carry out investigations Journalist, Noha Atef, began a blog called 'Torture in Egypt'.
All the content is about torture crimes committed in Egypt and the relationship between policemen and citizens.
'Torture in Egypt' was started at the time when torture was not highlighted enough, at all.
Torture crimes were rarely mentioned on TV It was not very interesting to mainstream media.
So 'Torture in Egypt' highlighted it and it was inspiring to other internet users, especially bloggers to write about torture and even their views. Because what they were reading in 'Torture in Egypt' that was really shocking.
By uncovering human rights abuses in Egypt through though this blog,
Noha has managed to correct some serious injustices.
In 2007 a woman wrote telling Noha that her husband had been kept in prison for 14 years even though the courts had found him not guilty of the crime he was arrested for.
The court said that he was not guilty but the policeman, a certain policeman, kept him detained. And he was renewing the papers to keep him in jail.
And I wrote about it many times and I was following it up.
Noha's article was cited in mainstream media across Egypt.
The policeman involved in the case wrote to her upset at the public attention he was receiving.
A short time later the jailed man was released from prison free, as he should have been 14 years earlier.
Another effective investigation was carried out in Tunisia.
The story of the Tunisian aeroplane video began when a friend of mine, Tunisian activist and blogger was searching the internet for photos related to aeroplanes in Tunisia and he found the image of the Tunisian Presidential aeroplane in a website for jetspotters -- people who share photos of planes they have taken in airports.
He kept on searching and found more than 20 photos of the same Presidential aeroplane in different airports in Europe.
So he went to the Tunisian Presidential website and took the list of the official trips of the Tunisian President and compared that with the photos with dates and places of the photos of the Presidential plane in Europe and he found out that only one trip was official
So the question that he asked was
'Who is using the Tunisian aeroplane and why?'
He went out and made a video mashing up those images using Google Earth flying over the different airports where the plane was witnessed.
He published that on YouTube and engaged the Tunisian blogosphere to talk about issues of transparency and the abuse of power.
Big mainstream media like foreign policy magazine published the story and investigated the case and said that the Tunisian aeroplane was used by the first lady of Tunisia for some personal shopping in luxury shops in Europe.
As a result of the public attention this video received the government in Tunisia blocked YouTube and another popular video sharing site, Dailymotion.
Despite this, this story, like the Torture in Egypt blog shows how the internet can be used both as a tool to investigate abuses of power and to broadcast and spread the truth.
As digital tools become cheaper, more widespread and easier to use our ability to access, analyse and share information grows.
By linking new technologies with creative thinking communities and advocates can transform information into powerful action that defends and promotes human rights.
Tactical Tech have been working with rights advocates to use information for advocacy for over a decade.
In this film we've collected advocates stories and shown 10 tactics you can use to turn information into a force for change
If you'd like to implement some of these tactics Try using one of our toolkits and guides which will tell you how to use different techniques and provide you with the software and tools you will need.
Then, think about how you can document your own info-activism stories and when you have done this, tell us so that we can share these stories with others.
The information age is here.
And with it comes the power for us all to make change.

One of the things we'd like able to do is to compute statistics on lists. Imagine that we've got a set of n nodes and we've got L, which is a list of values-- one for each of the nodes in the network and we want to compute statistics. What are statistics?
Astatistic is actually quite a simple idea. It's just a number that summarizes a list of numbers. If we have a list L--say a list of the centrality scores.
How many scores are in the list that are between 2 and 3 inclusive? These are all different statistics and some of these are may be more useful than others but there's lots of different statistics that we might want to compute. In general when you're doing an analysis of large structures like social networks, we need some way of summarizing this large amount of data--you can't just present the data in the raw form--it's too much for people to think of all at once.
Namaskaram. Please play it.

[intro music] It's a hot day in Rome, but you know, the ancient Romans had figured out how to stay cool. We're in a room that reconstructs a room in the villa of Livia.
Livia was the wife of the emperor Augustus. There is a lovely summer house, a resort of sorts,
Now there's one more error in this code, but it's tricky to catch and it's tricky because, the JavaScript engine of most browsers won't catch it either. Let's take a look at that for a second. Now, if you go back up to the top here, you might notice that there's no semi-colon at the end of this ent.update statement.
Let's take a look at the next step in searching for a business model, and that's customer validation. By now to get to this step we assumed you believe you have product market fit. Now, you would say, "Okay, now I can hire people."
"Now I could run my million dollar Google AdWords campaign," and we say, "No, not really." We don't really think you have enough evidence to do so. We kind of hear you that you believe you do, so we're going to do this again, but this time try to get orders or users or both, depending on what your business model said.
"Okay, I now have a lot of customer feedback." "How could I have best described this based on what the customers are actually telling me?" Because you'll ask "So, I explained it to you like this."
"Yeah, I ignored the first 7 things you said, but when you said number 8 that's when I really got interested and excited." And so you're going to develop both corporate or company and product positioning, and you're going to do this way before you ever spend money on external PR agencies by actually listening to your own customers. And then in Phase 4 you're going to verify or repeat, and you're going to see if you're ready to start scaling sales and marketing spending in customer creation, which is the most expensive part of a startup.
Let's say we have an ellipse formula, x squared over a squared plus y squared over b squared is equal to 1. And for the sake of our discussion, we'll assume that a is greater than b. And all that does for us is, it lets us so this is going to be kind of a short and fat ellipse.
So that's my ellipse. And then we want to draw the axes. For clarity.
That's the x-axis. This is the y-axis. And we immediately see, what's the center of this?
1, 2, 3. 1, 2, 3. I think this -- let's see.
-- pick a good color. It's going to look something like this. And what we want to do is, we want to find out the coordinates of the focal points.
-- since we're along the major axes, or the x axis, I just add and subtract this from the x coordinate to get these two coordinates right there.
The awakened awareness against engrossment in sweet mistakes This nature of our mind-body complex (prakruti) that still severely rebukes others, or causes suffering to them,
the kshayas, the aversion (abhaav) [that occurs] we want to clean all of these [mistakes] as many times as these mistakes arise in this, the ego still catches onto [the good that has happened] "Wow, I am in such excellent experience" Or these other things [mistakes]
And then a new type of moha arises; that of "knower-ship", That "I know it so well, I had lot of fun,
That is yet another pitfall. We want to progress in this way, that where do we still find sweetness in the worldly life? And when the bitterness stops, then the moha for mithaas tends to arise,
That is the bitterness decreases, when the suffering from insults occur, then we set gnan, "they are instruments (nimit), they are faultless, and they are a File". But we swallow the morsels of maan so quickly.
So we should catch this. We do say that," besides the experience of the pure Soul, I do not want anything else" but do make a list of what else we want. What are the things we feel sweet about, make a list
Then if someone says "you are good" then we become happy. If someone says "you are right" then we become happy.
"What you said is exactly right, your intellect is really good, you help so much in seva". We immediately swallow up that praises (maan). Sweetness (mithaas)
So let us take this advanced samayik, where have we derived sweetness in the worldly life (sansaar)? in eating, drinking, sleeping, money, to establish oneself, maan, impression, have our own way, what are the areas one takes sweetness in. And why doesn't it pinch us? Why we are still not fed up of this mithaas?
In areas where we have made a firm resolve, for instance, " I don't want vishay", then some amount of jagruti remains in these cases. But on the other side, not all the pratyakhyans for all the other mistakes have been made.
That is also a hole If there are no insults then it is good - that is also a type of "want". Security (hunf) of other people
"When even the slightest suffering occurs, I want to go towards the Soul" That should be our inner intent That should be our resolve
If we feel suffering from one thing then we [our vrutio] begin to feel, "Instead of this the other thing was better, it should have been like this". As long as one feels like this then we will not be able to come to our main home [that of Soul]
"I will only use this and not use that". If you investigate you will find that in this worldly life the vrutio are stuck in so many places. They are not free
It will surely come now... try another spoon, it will surely come... oh no happiness came..." then it [the ego] will experience that really there was no happiness in it [shikhand]. So in this way, we want the ego to experience the happiness and then become free from it. If we say "hey leave the shikand so you will not have any moha for it" that will not happen.
This discussion is not about cutting off what one likes but to keep this in our awareness and further to that after coming into gnan "oh likes this, likes this, likes this... I am in great experience of this gnan ..." if we find sweetness in that, then we will make a list of that as well. as this garbage within us is very dangerous
No matter how many luxurious hotels come our way or air condition taxis comes to take us around... we say "No buddy, I want to reach my destination of moksha". We cannot miss that goal. "Besides the experience of the pure Soul, I don't want anything else".
That goal cannot get missed. We want to keep this kind of awareness. And if we recognize these [mistakes] then the jagruti will remain
With pure applied awareness of the Self (shuddha upyog), in relative phases in relative relations in File number 1 whatever results are taking place whatever events (sanyog) or circumstances (avastha) arises in those wherever mithaas (sweetness) is being taken
[I am] becoming engrossed in [these mithaas] besides the experience of the pure Soul, I don't want anything else despite having this determination vrutio (inner tendencies) are slipping outwards and enjoying happiness for all those types of mistakes related to mithaas please grant me the absolute energy to see them separately in samayik the mithaas obtained from maan the mithaas obtained from moha the mithaas obtained from the happiness derived from the 5 senses the mithaas obtained from garvaras for any type of mistakes that have occurred for all those mistakes please grant me the absolute energy [ to see this] in samayik with awakened awareness to see this besides moksha besides the experience of the pure Soul in this worldy life
I don't want any happiness I am making an unflinching determination [May I] remain sincere to this determination please grant me the absolute energy [to do so] in that determination vrutios take happiness from outside whatever pol (deception and insincerity) arises for all those types of mistakes please grant me the absolute energy to recognize those mistakes
Entanglements of the intellect while solving files with equanimity There are two parts in this case: there is vengeance (ver) with people there is attachment and abhorrence (raag-dwesh) whether it is ver or it is illusory attachment (moha) there are two pitfalls attachment (raag) or abhorrence (dwesh) with people but as we continue to clean [older mistakes] a new puzzle arises for us "I am not able to progress further" and" I am not able to see my mistakes"
So today we will do this type of samayik Do you want to do this samayik or take something else? We should do this a little right? do the men have this kind of perplexity?
For each one the hat is made to the size of the head It is, it is and it is I too have some kinds as well
In this video we're gonna talk about the law of demand which is one of the core ideas of micro-economics. And luckily for us, it is a fairly intuitive idea. It just tells us that if we raise the price of a product, that will lower the quantity demanded for the product.
"ceterus perebus" all the relationship between price and quantity demanded. If we talk about an actual quantity, we should say the quantity demanded. So DEMAND vs QUANTlTY DEMANDED, these are two different things.
So here's my attempt at translating that description of an algorithm into actual Python code ended up using helpful structures maybe a little different than before so I've got a Dijkstra's algorithm.
Dijkstra is the name of the individual who first described and analyzed this algorithm for a single-source shortest path. So we give it a single source. We give it a single node in the network.

So security is two different things: it's a feeling, and it's a reality. And they're different. You could feel secure even if you're not.
"Should I stay, or should I flee?" And if you think about it, the rabbits that are good at making that trade-off will tend to live and reproduce, and the rabbits that are bad at it will get eaten or starve. So you'd think that us, as a successful species on the planet -- you, me, everybody -- would be really good at making these trade-offs.
Let's say I go to a store and I have fifty dollars in my pocket. fifty dollars in my wallet. And at the store that day they say it is a twenty-five percent off marked price sale. So twenty-five percent off marked price means that if the marked price is one hundred dollars the price I'm going to pay is going to be twenty-five percent less than $one hundred.
The discount is going to be twenty-five percent of x. But we know that this is the same thing as x minus 0.25x. And we know that that's the same thing as-- well, because we know this is onex, x is the same thing is onex.
And then the next year, let's call that year two, it shrinks by twenty-five percent. So this could have happened in the stock market. The first year I have a good year, my portfolio grows by twenty-five percent.
So if something shrinks by twenty-five percent, that means it's just going to be 0.75 or 75% of what it was before, right? one minus twenty-five percent. 0.75 times $125. So let's work that out here. $125 times 0.75.

So one has to understand some of the principles
Some of the principles First [one needs to know] what can one call stock of karma (bharelo maal) Many times mahatmas know it theoretically that all this is bharelo maal but when the bharelo maal comes out practically when it comes out then one doesn't realize that this is bharelo maal and that it is File number 1"s
So this awareness doesn't remain throughout "That this is all bharelo maal and that I am separate" Because what did we call bharelo maal? besides the pure Soul whatever remains in File number 1 is called bharelo maal.
but all this is foreign baggage it is a foreign border it is foreign! If that exact [awareness] remains 100% then there is nothing getting spoilt and everyone is in their correct place We are in our place and the bharelo maal is in its place
"I do not agree with what you are saying" So then that [bharelo maal] will play out its part and leave from our side, we don't have an opinion for it [the bharelo maal] That becomes declared
That is the ego a thought comes from the mind - he [the ego] instantly goes there Wherever the chit goes - he [the ego] goes there So he [the ego] becomes engrossed in all of these
Do you understand? That is how the stock of karma (bharelo maal] works; the mind, intellect, chit and ego are all bharelo maal the anger, pride, illusionary attachment, greed attachment - abhorrence are all bharelo maal that [bharelo maal] is coming out - keep this awareness And if the ego becomes engrossed even slightly, then the internal suffering will immediately start within you inside the "chun, chun, chun (slight form of internal suffering)" will start once this chun, chun, chun begins realize that this ego has gotten involved it has gone to sign
Then there comes such a stage where you simply know that he [the ego] has gone and he will come back immediately he will move back from that place and return [You tell him], "This is not your seat, your seat is that of pure Soul The thoughts that are coming are not yours
As soon as your vision asks this question, "where did he go?" you will immediately see that he [the ego] has gone to the intellect or [he] has gone to the mind or the ego [he] has gone to the Chit.
As soon as we realize that, "I the pure Soul am the knower", The direct light of the Self (pragnya) becomes present, and all of these [bharelo maal] sheds off No one's force works there, and all of them shed off
Good habits, bad habits all these are bharelo maal
Besides the pure Soul and the 5 Agnas everything else goes into the bharelo maal And our stock of karma (bharelo maal) has to be emptied out it is getting emptied out on its own now, We have to keep it separate and not become one with it We have to remain in our Knower - Seer state
So, today in samayik how do we keep this bharelo maal separate? how do we see the stock of karma separately? Today in samayik, see which type of bharelo maal is perplexing us It is not letting us stay in knowledge (gnan)
There are a lot of ways the people around us can help improve our lives. We don't bump into every neighbor, so a lot of wisdom never gets passed on, though we do share the same public spaces. So over the past few years, I've tried ways to share more with my neighbors in public space, using simple tools like stickers, stencils and chalk.
(Laughter) How can we lend and borrow more things, without knocking on each other's doors at a bad time? How can we share more memories of our abandoned buildings, and gain a better understanding of our landscape?
New Orleans has a parade. (Laughter) The city has some of the most beautiful architecture in the world, but it also has one of the highest amounts of abandoned properties in America.
I turned the side of this abandoned house into a giant chalkboard, and stenciled it with a fill-in-the-blank sentence: "Before I die, I want to ..." So anyone walking by can pick up a piece of chalk, reflect on their life, and share their personal aspirations in public space.
"Before I die, I want to be tried for piracy." (Laughter)
"Before I die, I want to straddle the International Dateline."
"Before I die, I want to sing for millions." "Before I die, I want to plant a tree." "Before I die, I want to live off the grid."
"Before I die, I want to hold her one more time." "Before I die, I want to be someone's cavalry."
"Before I die, I want to be completely myself." So this neglected space became a constructive one, and people's hopes and dreams made me laugh out loud, tear up, and they consoled me during my own tough times. It's about knowing you're not alone; it's about understanding our neighbors in new and enlightening ways; it's about making space for reflection and contemplation, and remembering what really matters most to us as we grow and change.
South Africa, Australia, Argentina, and beyond.
Our shared spaces can better reflect what matters to us, as individuals and as a community, and with more ways to share our hopes, fears and stories, the people around us can not only help us make better places, they can help us lead better lives. Thank you. (Applause)

We've got the function f of x is equal to x plus 2 squared plus 1, and we've constrained our domain that x has to be greater than or equal to negative 2. That's where we've defined our function. And we want to find its inverse.
So the point 5, 2 is, let me make sure. 5 minus 1 is 4. Square root is 2.
Have you ever come home to a note that made life just a little bit easier? A tip from someone you trust that helps you find the things you care about. When you have lots of options in front of you, it's easy to find yourself wishing for a bit of advice.
So, the first thing we do, is grab the body dom object using document.getElementByld, with an id of body, and we create a div object, as well as a canvas object, and set their id's appropriately to div.id = "gameContent" and canvas.id = "gameCanvas" and finally, we append the div object to the body and the canvas object to the div. If we open this up into our browser, we can see that we have indeed created a div element and inside that is our new canvas element and both with a proper id.
Let's assume I'm using Google AdWords and I'm paying $0.50 per pay-per-click. Now, let's assume my campaign at $0.50 each gets me 10,000 people to come look at my website. Well, $0.50*10,000, that cost me $5,000, but the goal isn't to just have people visit, the goal is to get them to the end of the funnel and at the end of the funnel,
Welcome to the presentation on why, not how, borrowing works. And I think this is very important because a lot of people who even know math fairly well or have an advanced degree still aren't completely sure on why borrowing works. That's the focus of this presentation.
Let's say I have the subtraction problem 1,000-- that's a 0. 1,005 minus 616. What I'm going to do is I'm going to write the same problem in a slightly different way.
1,005-- what I'm going to do is I'm going to separate the digits out into their respective places. So that is equal to 1,000 plus let's say zero 100's plus zero 10's plus 5.
1,005 is just 1,000 plus 0 plus 0 plus 5. And then that's minus 616. So that's minus 600 minus 10 minus 6.
616 could be rewritten as 600 plus 10 plus 6. And I put a minus there because we're subtracting the whole thing. So let's do this problem.
Into the 100's, 10's and 1's buckets. Well, we need 10 here, so let's put 10 here. So it's 10 plus 5 is equal to 15.
15 minus 6 is 9.
90 minus 10 is 80. 900 minus 600 is 300. So 300 plus 80 plus 9 is 389.
Let me do a simpler problem. I actually started off with a problem that tends to confuse the most number of people. Let's say I had
732 minus-- Let me do a fairly simple one. Minus 23. Sometimes those 3's just come out weird.
12 minus 3 is 9.
20 minus 20 is 0 and then you just bring down the 700. You get 700 plus 0 plus 9, which is the same thing as 709. And that's the reason why this borrowing will work.
Well, 2 is less than 8. I need a 10 from someplace. Well, one option we can do is we can just get the 10 from here.
12 minus 8 is 4. But here we see this 0 is less than 30, so we can't subtract. But we can borrow from the 500.
100 minus 30 is 70.
Bring down the 400. And this is the same thing as 474. And the way you learn how to do it in school is you say, oh, well, 2 is less than 8, so let me borrow the 1.
10 minus 3 is 7 and you bring down the 4. Hopefully what I've done here will give you an intuition of why borrowing works. And this is something that actually I didn't quite understand until a while after I learned how to borrow.
For this problem, we are to calculate the expected number of edges in an Erdos-Renyi graph with 256 nodes and a success probability of 0.25. But before we answer that question, I want to look at a simpler question where we have 4 nodes and a success probability of 1. In the case where the success probability is 1, every possible edge will be created.
>> Our solution for parsing the atlas definition is pretty straightforward. First, we're given atlasJSON data that's been loaded from an xhr request. The first step that we need to do is actually go through and call JSON.parse on that.
All right, this time we're going to do just a tiny bit differently. What we're going to do is we're going to search this graph starting from b and we're going to mark as we go the order in which we've added things to the open list. So, we started off with b, the only thing on the open list, we visit both the neighbors of b add them to the open list, pull c off the open list, add it's neighbors d, b, and we work on d, take it off the open list, add its neighbors e and c.
>> In addition to that atlas we have, we also have a very large and very complex data file. This data file represents how the atlas should be rendered to draw the entire map. Now this is a pretty complex file because its actually been generated by an external tool, called tile.
So just to recapitulate some of the stuff we talked about in this unit, ultimately, we talked about various different kinds of graphs, various different kinds of growth rates, the whole notion of Big Theta and Big O notation to capture asymptotic growth rates and connecting these things up with various kinds of recurrence relations. There ended up being kind of a nice correspondence between several different kinds of graphs, several different kinds of recurrence relations, and several different growth rates. These growth rates are obviously important for understanding how these graphs work, but they are really important for algorithm analysis, as well, and we're going to see algorithms with various run times that look like these as we proceed.
A ticket agent sells 42 tickets to a play. The tickets cost $29 each. Use rounding to estimate the total dollars taken in from the sale of the tickets.
29, if we round to the nearest ten, 9 in the ones place is greater than or equal to 5, so we round up. The nearest ten is 30. And another way to think about it.
I've talked a lot about precision and the inclinations I have not told you "why" this is happening...I am not going to go into the physics of it.
So I've been requested to do the proof of the derivative of the square root of x, so I thought I would do a quick video on the proof of the derivative of the square root of x. So we know from the definition of a derivative that the derivative of the function square root of x, that is equal to-- let me switch colors, just for a variety-- that's equal to the limit as delta x approaches 0. And you know, some people say h approaches 0, or d approaches 0.
I'm going to multiply the numerator and the denominator by the conjugate of the numerator is what I mean by that. Let me rewrite it.
Once you spend enough time designing algorithms to solve specific problems you start to realize that some problems don't seem to allow for efficient solutions.
Last year at TED I gave an introduction to the LHC. And I promised to come back and give you an update on how that machine worked.
And for those of you that weren't there, the LHC is the largest scientific experiment ever attempted -- 27 kilometers in circumference.
"No they don't. They're small wires." They can do that because when they are very cold they are what's called superconducting wire.
In one of the joints between over 9,000 magnets in LHC, there was a manufacturing defect. So the wire heated up slightly, and its 13,000 amps suddenly encountered electrical resistance. This was the result.
>> Baz Luhrmann: The subject today is location.
Location, location, location.
Can you imagine what a subject that is when you're setting out to make a sweeping romantic epic that by its very nature must use the landscape, the great outdoors to amplify and express drama? [ Music ]
>> Because it is an epic, it's a true epic, the [inaudible] of the locations had to be epic. [ Music ]
>> Baz Luhrmann:
The location that we needed to shoot this film on, there's in Australia what's called the Near Outback, which is an Outback that's closed, but there's also a place in the north of Australia, the faraway north which is really the faraway of the faraway, which even today in a world which increasingly you can just about go anywhere, is truly a frontier.
It's truly vast.
It's truly inaccessible, and it's truly empty. [ Music ]
>> In the Kimberley, we found an area that we can get to.
The most incredible variation between beautiful billabongs.
The [inaudible] ranges.
Salt flats that in a distance of ten or so kilometers change color, change the look of them, of what you see here. [ Music ]
All of those great big epic expanses we've been able to get in the short distance. [ Music ]
Well, there was always a concept design that had a mountain that's remarkably like that, a river at the base of the mountain and the homestead between the river and the mountain.
I came and scouted this around about August 2005 for the first time.
I came down the road over there, took some shots at dusk looking back at the mountains, which at the time I'm taking, look pretty special.
They were printed up and taken back to Sydney amongst lots of other photos of the area, and Baz hesitated over the photos and then went back to them, and then we came back.
We surveyed, and this was where the homestead was going to be. >> Ian Gracie:
We're sort of making a picture that's, you know, in the true Bazmark way it's going to look good.
If a mountain wasn't here, we wouldn't be here.
We could be almost anywhere, but the mountain was our guiding element. >> Baz Luhrmann:
We never left them, and I think one of the attractions for me to make this next film was to re-engage in my great romantic love of those sweeping location epics, and the idea of going out onto an exotic faraway location with a 300 plus crew to try and capture an emotional romance was in itself a really exciting prospect. >> Hugh Jackman:
To be out on location for so long and movies this big is so hard to pull off. >> To bring this number of people, this number of vehicles, 55 trucks and all the other things that we've got, to bring them this distance is, has never been done in Australia before at this level.
[ Music ]
Somewhere over in the mud flats back there there's a whole unit circling [inaudible] and doing things like that.
We're just a little bit away from them, but, hey, we had to build a road to get here this morning.
Once you're on the flats here, we're OK, but infrastructure and logistics, that's what it's all about for a movie of this size. >> Hugh Jackman:
I think you capture something out here that you never can recreate even with the best visual effects.
As an actor, of course, it makes it a lot easier to come to places like this that at best you get to see from about 40,000 feet in the air, you know, in an airplane.
It's an honor really to be able to do it, and every day me and my [inaudible] Francesco we say thank you, Baz.
Thank you, Baz.
Because without Baz and his crazy vision,
First thing we start off with is, we create a variable here called Render Engine Class and you define a variable by starting with the keyword var, and then the variable name, and then you say equals, whatever you would like it to be equal to. In this case we use an opening brace, to indicate that we'd like this to be a javascript object. This is the object literal notation, for defining an object in Javascript.
It's important to analyze the running time of this algorithm so we have some idea of how efficient it is. And again, that's going to involve counting up the number of primitive steps, primitive statements, time that the algorithm takes when solving a problem. We'll assume, as before, that n represents the number of nodes in the graph and m represents the number of edges.
So yeah, I'm a newspaper cartoonist -- political cartoonist. I don't know if you've heard about it -- newspapers? It's a sort of paper-based reader.
(Laughter) It's lighter than an iPad, it's a bit cheaper. You know what they say?
(Laughter) Ladies and gentlemen, the world has gotten smaller. I know it's a cliche, but look,
(Laughter) Any computer designers in the room?
Yeah well, you guys are making my life miserable because track pads used to be round, a nice round shape. That makes a good cartoon. But what are you going to do with a flat track pad, those square things?
(Laughter) Don't go asking for a Frappuccino there. So we are bridging the digital divide.
Yeah. Well, the Internet has empowered us. It has empowered you, it has empowered me and it has empowered some other guys as well.
(Laughter) You know, these last two cartoons -- I did them live during a conference in Hanoi.
(Laughter) So I was cartooning live on a wide screen -- it was quite a sensation -- and then this guy came to me. He was taking pictures of me and of my sketches, and I thought, "This is great, a Vietnamese fan."
(Laughter) No, but it's true: the Internet has changed the world. It has rocked the music industry; it has changed the way we consume music.
(Laughter) And it has changed the way your future employer will look at your application. So be careful with that Facebook account -- your momma told you, be careful.
(Laughter) In short, technology, the internet, they have changed our lifestyle. Tech guru, like this man -- that a German magazine called the philosopher of the 21st century -- they are shaping the way we do things.
(Laughter) (Applause) You will not like it. And technology has even changed our relationship to God.
(Laughter) Now I shouldn't get into this. Religion and political cartoons, as you may have heard, make a difficult couple, ever since that day of 2005, when a bunch of cartoonists in Denmark drew cartoons that had repercussions all over the world -- demonstrations, fatwa, they provoked violence.
(Laughter) In 2006, a few months after, I went Ivory Coast --
I was there to report on that story in cartoons. I've been doing this for the last 15 years; it's my side job, if you want. So you see the style is different.
(Laughter)
"Another time." So back in Abidjan, I was given a chance to lead a workshop with local cartoonists there and I thought, yes, in a context like this, cartoons can really be used as weapons against the other side.
So, preaching for freedom of speech is easy here, but as you have seen in contexts of repression or division, again, what can a cartoonist do? He has to keep his job. Well I believe that in any context anywhere, he always has the choice at least not to do a cartoon that will feed hatred.
Thank you.
(Applause)
What I wanna do in this video is step trough the insertion sort function that we wrote in the last video. But before I do that I actually just want to focus on one part of it, cuz I realized that I used something that you probably don't reckognize cuz we haven't used it before. I used...
Alright, now that we've got some better tools, let's take a look at a bigger piece of code. Now this is the entire base game engine class for the game that we're going to be building. Now, what I'd like you to do, is debug this much
So, what was interesting was number 1, shared economics. Well, that was right. You both have an economic reason to want a partner.
Convert 51.8 decimeters to kilometers. So let's just think about what decimeters means in terms of meters, and then we can think about what kilometers mean in terms of meters, and then convert them. So we're going to start with 51.8 decimeters.
And we need this because this decimeter and that decimeter are going to cancel out, and we're going to be just left with meters. Now 1 meter is how many decimeters? Well, the prefix deci means 1/10.
10 of these make up 1 of these, or 1/10 of a meter per decimeter, which is exactly what that is telling you. 1/10 of a meter. Now if you multiply these two things, what do we get?
Multiplying by 1/10 is the same thing as dividing by 10. So this is going to be equal to 51.8 divided by 10. The decimal's just going to move to the left.
So we're going to want meters in the denominator and kilometers in the numerator. Why? Because this meter and that meter will cancel out.
Where we left off on the last video, I think we're getting a reasonably good appreciation for how huge the Sun is especially relative to the Earth and how far the Earth is away from the Sun.
And most of these diagrams that we see in science textbooks, they don't give justice...
In fact, when I showed this Sun over here that was about 5 or 6 inches across,
I said that the Earth would be this little speck, about 40 feet to the left or the right, or its orbit would have a radius of about 40 feet.
It would be this little speck orbiting at this huge, huge distance. If you look at this Sun over here
So in this situation, this Earth right here
--this is drawn to scale-- this Earth would not be anywhere near this close, it would be about 200 feet that way, or about 60 or 70 meters.
There are a lot of web 2.0 consultants who make a lot of money. In fact, they make their living on this stuff. I'm going to try to save you all the time and money and go through it in the next three minutes, so bear with me.
It's always rising, falling; a half million people visit every day. But this isn't about Reddit. It's about discovering new things that pop up on the web.
(Laughter) And this was a special name. Mister Pants, or "Splashy" to his friends, was very popular on the Internet.
"What a great thing, we should all vote this up." And Redditors responded and all agreed. So the voting started.
And it wasn't long before other sites like Fark and Boing Boing and the rest of the Internet started saying, "We love Splashy Pants!" So it went from about five percent, which was when this meme started, to 70 percent at the end of voting. Pretty impressive, right?
(Laughter) And the Reddit community -- really, the rest of the Internet, really got behind this. Facebook groups were created.
Everyone wants to hear their news anchor say, "Mister Splashy Pants." (Laughter) I think that's what helped drive this.
Greenpeace was thrilled, the whales were happy -- that's a quote. (Laughter) And actually, Redditors in the Internet community were happy to participate, but they weren't whale lovers.
Thank you. (Applause)
The Wrong belief of Doership Today our topic for satsang is
The wrong belief of doership (kartapanani bhranti) In the path of spiritual evolution (samsaran marg) from the single-sensory (ekendriya) organism [we have come] from embodied souls in an unnamed state (avyavahar rashi ) to a manifested state (vyavahar rashi) after coming into the vyavahar rashi we moved from the single-sensory (ekendriya) organism to two senses, namely touch and taste (beindriya) to three senses to four senses to five senses to animals after wandering in so many 8,400,000 sources (yoni) [We've evolved] from monkeys to chimpanzees
After wandering through all these cycles going through these cycles wandering through them, we have come then after coming into the human form this wrong belief of doership (kartapanani bhranti) arises
until then everything was in darkness this wrong belief did not exist "I am the doer" didn't exist The sensory organs are not yet fully developed either even the mind (mun), intellect (buddhi), Subtle component of vision and knowledge (chit) and Ego are not fully developed
If he does good work, he does selfless work for people, or he helps others, he does good work Then everyone compliments him "Oh, what great work you are doing"
"God is doing all this, I am not doing anything" But internally he is tasting the 'sweet juices of doership" (garvaras)
"I am not doing anything. God is doing all this" "What can I..."
This is not only kartapanani bhranti but it is with deceit how sticky did he make it? Because the buddhi has increased So it learned this as well
He'll say "I am doing it because of Dada's grace" "Or else I wouldn't know how to" But internally he tastes the sweet praises
He believes the actions of the mind as "I am doing" The thoughts are sprouting on their own whatever was charged is now discharging And yet what does he believe?
The speech is coming forth on its own it is a tape recorder that is playing Yet he believes "I am the one speaking" "How well I spoke!"
Even if the other person didn't want to say anything He has to [answer] because the question was posed he has to say "you spoke really well" Then he feels "Wow, how well I spoke"
So many wrong beliefs engulf a person [the belief] of "I spoke"
Then when the buddhi makes some decision Now the buddhi is making this decision based on vyvavasthit The Ego (Bappu)
Against the wrong belief of doership the knowledge that vyavastit is the doer is the only antidote to kill that belief Real knowledge (gnan) against deluded (mithya) gnan is always the antidote to kill it And vyavasthit is the doer
No one is the doer Where you have said scientific circumstantial evidence is the doer Then who is the doer in that case?
where does the evidence even remain where is the Self? It is said to be an evidentiary instrument (nimit) Nimit and doer
the difference is as vast as the earth and the sky Nimit means simply his presence he is equivalent to a catalyst what doership is there of a catalyst? Because we give the catalyst a name that is the reason why it happened the experiment was completed
And another equivalent wrong belief (bhranti) Bhranti number 2 It is through scientific circumstantial evidence that everything is occurring but one believes "I am doing [it]"
If one was the doer If one is actually doing it Then when he wishes [to do]
doership is under the power of other forces (par-satta) instead he believes it [doership] is under the power of the Self (swa-satta) The power to do [is under him] That is bhranti
And then more than that there are so many other wrong beliefs I am her husband
I am his father I am his son I am his boss
it is temporary it is constantly changing also as long as the discharge ego still has a stance until then the belief that "I am the doer" will exist If we become the knower of that discharge ego Then this belief doesn't arise and the discharge ego doesn't interfere in between
because during discharge there is no doership it [the discharge] occurs automatically but because he [the ego] has a habit, he believes [he is the doer] it is his belief, he only just believes [in reality] he doesn't do anything And because this belief arose, then something new starts We don't have anything new arising
As much spiritual awareness (jagruti) you maintain at this level and you don't give it any support Then it will quickly get emptied out by that much Do you understand?
That is how you should stay separate vyavasthit is the doer That should remain in your awareness From morning to evening vyavasthit is the doer
Jai Sat Chit Anand
So I just want to tell you my story. I spend a lot of time teaching adults how to use visual language and doodling in the workplace. And naturally, I encounter a lot of resistance, because it's considered to be anti-intellectual and counter to serious learning.
Thank you! (Applause continues) Thank you very much.
(Laughter) But he wrote that for his wife. (Laughter)
(Applause) Now comes the part that I hate. Well, because Mr. Anderson told me that this session is called "Sync and Flow,"
I was wondering, "What do I know that these geniuses don't?" (Laughter) So, I'll talk about musical composition, even though I don't know where to start.
(Laughter) (Applause) Jennifer Lin: Nice to meet you.
OK, that's nice. So, I'm going to have a moment to think, and I'll try to make something out of it.
(Music ends) (Applause) The next song, or the encore that I'm going to play is called "Bumble Boogie," by Jack Fina. (Applause)
(Music ends) (Applause)
An optional piece of software is something called launchpad central at www.launchpadcentral.com.
The launchpad central allows you to share your work, your customer discovery narrative, what's you're doing outside the building with mentors and instructors and everybody else. Some of you might think, "Well, I don't want to share what I'm doing," but it's not sharing your IP or your great ideas--it's actually sharing what you found out in testing your hypothesis and it allows others to comment in real time. So in fact, you won't have to sit alone thinking about "Am I on the right path or is this the right strategy, etc."
Why grow homes? Because we can. Right now, America is in an unremitting state of trauma.
(Laughter) And we know it's incredibly ugly. It could have been an English Tudor or Spanish Colonial, but we kind of chose this shape.
(Applause)
We are asked to identify the percent amount and base in this problem. They ask us 150 is 25% of what number? So another way to think about it is 25% times some number, so I will do 25% in yellow.
