  • Hey! I'm Jacob Barnett, are you guys excited?

  • (Cheers)

  • Alright!

  • I am here to tell you why you guys should forget everything you know,

  • right now!

  • So, first thing you guys need to know:

  • suppose you guys are all doing your homework.

  • OK, you know, it's something you have to do;

  • and, you're doing great on your homework,

  • you are getting great grades, fabulous prizes, such as you know,

  • Benjamins and all this great stuff.

  • I'm here to tell you that you're doing it all wrong!

  • That's right, I did just say that, you're doing it all wrong!

  • In order to succeed

  • you have to look at everything with your own unique perspective.

  • OK, what does that mean?

  • That means that, when you think,

  • you must think in your own creative way,

  • not accepting everything that's already out there.

  • By the way,

  • the people I'm showing you in the background are my little brothers Ethan and Wesley,

  • one of them is a chemist and the other one is a meteorologist.

  • So, your perspective might be the only way you can see

  • art or history or music, or whatever.

  • So, let me show you one of the ways in which I can see math.

  • So, for example,

  • that's 32 and the rotations represent:

  • addition, subtraction, division, multiplication, etc.

  • My main reason of coming out here

  • is to do some quantum mechanics, OK?

  • So, today, what we're gonna do is,

  • we're gonna do the Schrödinger equation,

  • split it into time independent components,

  • and we're gonna solve it for

  • the boundary conditions of a lattice and a particle in the box.

  • So, let's get to work!

  • So, I have some lecture notes, which I'd like you guys to pass out.

  • I'm gonna split them into two rows.

  • So, if I can have some people come up and get these?

  • No, wait. Before you come up here

  • I need to let you know about something very quickly.

  • OK, just stay there. I'm kidding!

  • (Laughter)

  • I didn't -- (Applause)

  • I did not come here to frighten you all with quantum mechanics -- not yet.

  • So, let's think about something simpler.

  • How many of you here have heard about circles?

  • OK, good.

  • So, why are circles important?

  • They are the shape of cookies.

  • They are the shape of skateboard wheels,

  • and most importantly,

  • they're the shape of the thing that turns on your X-box 360.

  • (Laughter)

  • So, what do we know from school about circles?

  • We know Pi r2, we know they're round.

  • Do we know anything else?

  • Not really.

  • (Laughter)

  • So, let me tell you something cool you can do with circles.

  • It's called Johnson's Theorem.

  • It's not really a theorem, it's just, you know,

  • a way mathematicians can think of stuff.

  • So, what Johnson said was,

  • "You take three circles,

  • you overlap them in a way so that there's six blue lines" --

  • where I call each of the circles blue;

  • so there's six lines coming in one point.

  • The other three points are in a circle of the same size;

  • Interesting.

  • So, this isn't just Pi r2, This is something new.

  • So because Johnson didn't just think:

  • "Oh, it's gotta be Pi r2 and round, that's it,"

  • he created math.

  • And he did it in his own unique perspective way.

  • So, now I know not all of you are necessarily mathematically gifted,

  • so --

  • (Laughter)

  • so, let's move on to some more interesting stuff.

  • By now you might have heard about Isaac Newton in your High School career.

  • You might have heard about him from prisms

  • or whatever he might have done.

  • So, in 1665, Isaac Newton was at the University of Cambridge.

  • Now, for those of you who really know your history,

  • at that time Cambridge had closed due to the plague.

  • So, Isaac Newton, he didn't have a way to learn.

  • He had to stop learning, and he was probably,

  • hiding in a dormitory with his cat running from the plague.

  • Now, while he was doing this he decided he had to stop learning,

  • but he didn't want to stop thinking.

  • OK? So, because of that he was thinking about this problem in astrophysics.

  • And specifically I think he wanted to calculate

  • the motion of the Moon around the Earth,

  • so I sort of revamped that problem into the case of Mercury around the Sun.

  • So, OK.

  • What he did was, in order to solve this problem he created calculus,

  • Newton's three laws, the universal law of gravitation,

  • the reflecting telescope to check his work, and optics,

  • and all this crazy stuff in that two years that he had stopped learning.

  • So, I guess that was really good for us,

  • because at that time Newton had to stop learning;

  • but when he stopped learning he started thinking and he created science.

  • And, OK, that's just great, we now have a theory of physics!

  • So, OK.

  • He could have probably been some top scholar,

  • he could have had a 4.0 GPA,

  • he could have been on the dean's list,

  • he could have had his professors proud;

  • but he wouldn't have created anything

  • if he didn't stop learning.

  • Newton needed to start thinking,

  • and think of things out of his own unique perspective,

  • in order to create his theory.

  • So, now let me formally introduce myself

  • because I did not do that at the beginning of the talk.

  • So, about 11 years ago I was diagnosed with this thing called autism.

  • What that meant was I was focusing on things in such extreme detail,

  • that it seemed I wasn't thinking at all.

  • Basically I'd be like,"Oh, look here's this reflection of that light,

  • so there's light up here, but, oh, there's my shadow,

  • so there's a light back there" and I looked over and it's over there.

  • (Laughter)

  • OK.

  • So, because of that, you know,

  • people thought I would never learn

  • because it just looked I was just staring into the opening;

  • it looked like I wasn't doing anything at all.

  • So, people told me I would never learn, I'd never think,

  • I'd never talk, I'd never tie my shoes, which --

  • OK, they might have had a point, you know,

  • I'm wearing sandals.

  • So -- (Laughter)

  • You know, but however, at that age,

  • I went to the Barnes and Noble, and I got a textbook,

  • and from the data that was in that textbook I derived Kepler's laws.

  • When I wasn't supposed to be learning or thinking at all.

  • So, basically from the other people's point of view

  • it wasn't really looking too good, I wasn't fingerpainting, or doing story time,

  • or any of the other stuff the 2-3-4 year olds would do;

  • but, you know, what they did was, because I --

  • they took me to special Ed.,

  • which is extremely special

  • in the fact that it didn't educate me.

  • (Laughter)

  • So, during that time I had to stop learning

  • because I didn't have a way to learn, you know,

  • I was just in special Ed.

  • So what they would do is --

  • So, I wasn't able to learn anything at all.

  • However, at that age I started thinking about things

  • and sort of the way of all of these shadows,

  • and I think that's why I like astrophysics, and physics, and math today;

  • because I had to stop learning,

  • I believe that's why I do what I do today.

  • OK, so let me continue about gravity.

  • It's a very exciting topic for those of us who are in physics.

  • So let me continue.

  • Now, what happened was,

  • about a couple of centuries later,

  • the physicists had enough experimental technology to test Newton's orbit.

  • Now, Newton predicted that the orbit of Mercury was an oval,

  • or as scientists like to say "an ellipse."

  • However, when we pointed our telescopes out, we saw that thing.

  • For those of you who are scientists you know that's extremely exaggerated, but --

  • This was not looking good, Newton had failed.

  • One of the greatest physicists, of all minds, had failed, he failed!

  • (Laughter)

  • So, we needed someone else, just like Newton had done,

  • to forget everything they knew!

  • And you know, recreate this.

  • That man's name was Albert Einstein.

  • Albert Einstein, what he would -- he was also --

  • he was stopped in his tracks, he was not doing very well.

  • He was Jewish and it was pre-Nazi Germany,

  • so, he was not able to get a position at the local university.

  • He had to work at a patent office;

  • which, OK, that's not theoretical physics, and we're talking about Einstein here.

  • So, yeah,

  • what happened was, Einstein, he had all this time to think all of a sudden.

  • He had to stop learning, but he had all this time to think;

  • and so, what he had done was,

  • he liked to have these thought experiments

  • and liked to think about all these different things.

  • So what Einstein thought was,

  • OK, he pictured himself on a trampoline with a couple of friends,

  • which -- they are actually -- a failure of my sentence there,

  • and the fact that physicists

  • that's usually a couple more than they have.

  • (Laughter)

  • Albert Einstein was probably on a trampoline with one of his friends,

  • and you know, they were probably playing some,

  • I don’t know, tennis or something.

  • So, however, you know, they are physicists,

  • they don’t have very good hand to eye coordination,

  • so they probably didn't, you know,

  • catch the tennis ball, and it went rolling around them;

  • and Einstein looked at this and said,

  • "Without friction, this is gravity!"

  • He realized, "This is just gravity."

  • So, afterwards, he predicted the motion

  • which is gonna end up like that crazy thing;

  • but that crazy thing is exactly that other crazy thing.

  • So, Einstein had solved the problem

  • just by thinking about it in his own unique perspective,

  • in his own unique way.

  • He stopped learning, and he started thinking,

  • and he started creating.

  • So now let me get back on the story, you know,

  • I wasn’t really looking too good,

  • so I just kind of brush it over there.

  • So, about three years ago, I --

  • OK, there was a calculus class I wanted to sit in the back of,

  • so, I decided, in order to sit in the back of this,

  • I am going to learn: algebra, trigonometry,

  • all this other middle school stuff,

  • all the high school math,

  • and first year undergrad calculus in two weeks,

  • so I could sit in the back of this class.

  • I was ten.

  • (Laughter)

  • Okay --

  • So, also at that time, proving this,

  • I got accepted into the University;

  • and yet again I was still ten.

  • So, OK, then I had to go to an entrance interview,

  • you know, that’s what you gotta do, its a university.

  • So, I had to go to this entrance interview,

  • and because of parking, I had all these coins,

  • and, you know,

  • I dropped them all over the guy's office;

  • making him think I had no common sense

  • and he pretty much held me back for a semester.

  • So, I also had to stop learning at that time.

  • OK, what did I do?

  • Did I stop learning and just, you know, start playing video games and stuff?

  • No!

  • I started thinking about shapes!

  • (Laughter)

  • And I was thinking about this specific problem in astrophysics

  • that I was really interested in at that time,

  • which I still kind of am.

  • Now, what I did was,

  • over the next two weeks I started thinking about these shapes,

  • I started thinking about this problem,

  • and after a while I had solved it.

  • So, I have solved this problem in astrophysics,

  • which basically is similar to,

  • you know, what's happening with Einstein and Newton right now.

  • I am not going to tell you the exact problem

  • due to the fact that I have not published it, yet.

  • When my paper gets published, you may figure out about it;

  • (Laughter)

  • for those who read scientific papers.

  • (Laughter)

  • I thought about all these problems and you know,

  • I only has a 500 cheap thing of paper from Officemax;

  • and since I was thinking about these multidimensional things,

  • it filled them up really quickly.

  • So, then I moved on to white boards because I was out of paper.

  • But the white board, it also filled up pretty quickly,

  • so then I moved on to my parents' windows.

  • After that I got chased down by all this Windex and stuff

  • and, you know, my equations would get erased by these horrible Windex creators but,

  • so, because of that,

  • after about a month or so,

  • my parents realized I was not going out to the park,

  • I was just drawing these weird shapes on the windows.

  • And basically I was trying to disprove myself,

  • you know, I didn’t want to end up like Newton;

  • I did not want to, you know,

  • be proven a hundred years down the road, disproved.

  • So, what I did was, I was going on the windows,

  • I was trying to disprove myself, but to no avail.

  • After that, my parents,

  • you know, they figured I should be on the park,

  • so they called some guy up at Princeton,

  • and they told him to disprove what I was doing.

  • Unfortunately that wasn't the case, and he said I was on the right track;

  • so, I'm not going to the park.

  • (Laughter) (Applause)

  • Then because I had to stop learning,

  • I started thinking and I solved the problem.

  • After that I decided to create a calculus video

  • for other people who wanted to still do calculus;

  • the three others out there, and,

  • so that way they could also learn.

  • OK, so, I made this calculus video,

  • people noticed that I was 12 and I was doing a calculus video.

  • After that, the first people that noticed was the Indianapolis Star,

  • and they put me on the front page of some newspaper

  • and as you can see from this picture,

  • I was eating a sandwich, it was really yummy.

  • So, OK.

  • After that, my calculus video, it went viral.

  • At the time of this photo it had some two million views.

  • So, first of all a calculus video going viral, who would have ever thought?

  • (Laughter)

  • So, after that it got translated into whatever this language is.

  • Is there anybody who can tell me what language this is?

  • I can't read it. (Audience) Chinese

  • OK, it's Chinese, OK, good to know.

  • (Laughter)

  • So, then after that, I had some guy from Fox TV call me up,

  • and I was able to draw on his windows, and he was Glen Beck.

  • (Laughter)

  • The thing special about that experience was that the windows were huge,

  • 23 floors above the ground, and overlooked the Chrysler Building,

  • so that was a fun experience.

  • (Laughter)

  • Then after that I started having some really strange visitors show up to my house.

  • (Laughter)

  • I had Morley Safer show up, and he's from CBS Sixty Minutes.

  • Now, for those of you who can really see this picture very well,

  • you may notice that I am wearing the same sandals.

  • (Laughter)

  • Now, let's sort of recap what we've done.

  • Have Einstein, and Johnson,

  • and Newton, and everyone I talked about,

  • are they really geniuses?

  • Is that really what has made them so special?

  • Is that really why they did all their work?

  • Absolutely not! They, no!

  • That's not why! (Laughter)

  • OK, so, what happened was, all they did was,

  • they made the transition from learning,

  • to thinking; to creating,

  • which by now the media has translated into, you know, genius.

  • Now, I'm pretty sure they had relatively high IQs;

  • but, as some of you may know,

  • there are lots of people out there with high IQs who don't create this sort of thing,

  • they usually just end up memorizing a couple hundred thousand digits of Pi.

  • So, first of all, my question to them is: why not memorize a different number?

  • Like, I mean, I am wearing Phi right now.

  • So, in conclusion,

  • I am not supposed to be here at all,

  • you know, I was told that I wouldn't talk.

  • There's probably some therapist watching this who's freaking out right now.

  • (Laughter) (Cheers) (Applause)

  • OK, I am not supposed to be talking, I am not supposed to be learning;

  • but because I made that transition from learning to thinking, to creating,

  • I am here today;

  • and I am talking to some four hundred to eight hundred people in New York.

  • OK.

  • Now, what would I want you guys to get out of this speech?

  • What I want you guys to do is, for the next 24 hours,

  • I know you guys may have school or what not, even though it's a Saturday;

  • for the next 24 hours don't learn anything!

  • You are not allowed to learn anything for the next 24 hours.

  • (Audience) Yes!

  • (Laughter)

  • However, what I'd like you to do is,

  • I'd like you to go into some field,

  • I mean, you all have some passion, I don't know about it,

  • I've been talking to you for 11 minutes.

  • I have no idea what you guys are interested in.

  • But, you guys have some passion and all out there

  • and you all know what it is.

  • So, I want you to think about that field

  • instead of learning in that field;

  • and instead of being a student of that field,

  • be the field!

  • Whether it's music or architecture,

  • or science or whatever;

  • and I want you to think about that field

  • and, who knows, maybe you can create something.

  • Thank you very much. I'm Jacob Barnett.

  • (Cheers) (Applause)

Hey! I'm Jacob Barnett, are you guys excited?
