The Extraordinary Theorems of John Nash - with Cédric Villani

[@rodovre]

This remarkable mathematician, always with the same eccentric look and heavy French accent, now became a member of the French parliament! Awesome to have a mathematician in politics, a new wave.

[@fboileau1]

in france not that much, les francais ils aiment quand meme les intellos depuis un bout

[@linchenpal]

Greek times are coming back

[@FISHDINHO]

Using mathematics to predict economic markets caused the 2008 banking collapse. It's far from ideal.

[@linchenpal]

Dougaldinho Fishdinho not complety true: an application of math: deterministic formules following a normal distribution. Read about the warning from academia at the time and how for ex Fractal coulf have avoid it.

[@innertubez]

This is like a science lecture delivered by a magician.

[@gresach]

A beautiful lecture, communicating with kindness and humility, so much of the spirit of mathematics

[@abcde_fz]

God I wish this guy had more lectures. His voice, to a middle-of-the-road american English speaker such as myself, is so very well adapted to getting both the technical AND aesthetic nuances across, to me at least, that I could listen all day to stuff I don't even begin to understand, and still enjoy it immensely... :-)

[@NoriMori1992]

I love when non-native English speakers speak English more than well enough to be understood, but don't speak in quite the same way as native speakers. They say things in the most poetic and beautifully succinct ways. I also love when someone speaks English well and clearly but still has a really strong accent; there's something really satisfying about it.

[@OfficialTaj]

ME TOOOO!

[@skylark.kraken]

Definitely, how he called instructions to make a hyperbolic crochet a "recipe" 👌

[@deepakbellur9676]

I was about to say he spoke most interestingly but very tiringly!

[@mkrump9403]

He lives more than a decades in USA and never loss his french accent... The power of math and science haha.

[@mkrump9403]

His tough as nail french accent*

[@antonteodor6305]

You know you're talking with a Frenchman when analysis is being compared to fine cuisine...

[@Extys]

Actually it's because the word in Japanese is the same "fine cuisine" and "analysis". 22:10

[@antonteodor6305]

Yeah sure xD

[@AnandKrishAK]

May I know the Japanese word?

16:55 "Hyperbolic Crochet." In The Hitch-hikers Guide to the Galaxy, an entertaining 'Fiction' by the late Douglas Adams, R.I.P., there are some very large creatures. The width of their "Crochet Thread is standardised at one light year broad The Crochet hooks are five light years diameter by 200 light years length. These very large creatures only exist to make "Hyperbolic Crochet" and they do not understand the concept of "Large". to them everything is a normal size.

[@XrollhaX]

This talk was amazing. The first 12 minutes make you realize by yourself the following minutes of the video and Cédric keeps up giving us more and more. Amazing explanation. Glad I could watch it on KZbin.

[@brboLikus]

"Here, let me show you an example." Camera: full frontal view. "See here how it changes..." Camera: better change to the left!

[@ashnur]

probably they didn't want to share the exact graphics with the internet

[@brboLikus]

It was visible later in a full room view. But it was probably a technical issue since it wasn't shown through the presentation software. Great lecture, nonetheless!

[@hoangnamld]

They said the slides were given later after the talk, so they couldn't capture the graphics outside of his slides.

[@santiagobalado5505]

That's no excuse when they had footage of the screen themselves, as evidenced later.

[@infosec4u]

Un scientifique, un très grand savant ! On ne se lasse pas de l’écouter et de voyager dans le monde merveilleux de la mathématique. Je n’ai jamais vu autant de qualités pédagogiques , toujours prêt à écouter et à expliquer. J’aurais tant voulu l’avoir comme prof ! Merci beaucoup pour le partage

[@TwelfthRoot2]

I like how @ 41:49 he mentions conductor because a few years ago I was watching a completely unrelated video to math about a classical music awards ceremony in France and a pianist that I admire (Cyprien Katsaris) was getting an award. Well I spotted Dr. Villani in the the crowd. Of course I emailed the video to him for confirmation. He confirmed and laughed because I recognized him. Dr. Villani used to be a serious piano student when he was younger.

[@1vootman]

Aside from being a genius, He's an excellent teacher...something really needed these days.

[@LetsDark]

The missing slides at ~ 37:50 are very frustrating. :(

[@koenigmagnus]

Yes, we have to rely on his description.

[@EricEisaman]

Cédric is a brilliant communicator.

[@baptistewxpolpodcast3339]

Cédric is a national treasure ! Brillant exposé

[@friedrichbaumgarten8886]

His introduction has so much of literary beauty; I know he has quite high brow a literaric background but fairly unexpected; it is something mathematicians rarely have

[@ClementMasson]

Brilliant talk from Cedric, as always ! That was a moving tribute. I felt quite sad at the end of the presentation, hearing the circumstances of his death. Dying just after eventually gaining one of the highest acknowledgments, which he had been waiting for most of his life ... that's so dramatic ! A tribute movie could be very good, if only it really sticked to the real fact without over-dramatizing the thing.

[@TheR971]

I mean Galois wrote down all his ideas on finite groups the night before his death, without ever gaining acknowledgments. But he changed the world.

[@tobalaba]

Thank you Cédric and Royal Institution, from Argentina.

[@Hecatonicosachoron]

I just adore his enthusiasm! And also geometric flows and applications of diffusion equations to geometry, such a wonderful branch of maths!

[@mrjohnnybond]

missing some slides about the heat equations. very frustrate. otherwise very good presentation! thank you to all who were involved!

[@TheRoyalInstitution]

Sorry if this affected your enjoyment of the video. When editing we put in all the slides given to us by the lecturer and don't leave any out!

[@mrjohnnybond]

I think the video was very good, and well made too. the missing slides aren't that important, it is weird though that while he is frantically pushing his computer's buttons to illustrate something the video has his face in full. maybe a brainfart of a cameraman?

[@metapyziks]

I guess the cameras were all in fixed positions, with none of them showing the projected screen. Edit: Nevermind, they show a shot later on that can see the screen. It really would have helped if that camera was used while he was demonstrating that part.

[@Maxander2001]

Agree, I also found it very frustrating to watch him watch his slides. Argghh!

[@metapyziks]

True, but overall it was a really interesting lecture!

[@ShenghuiYang]

Both mathematics and this lecture are a piece of art.

I think my mother, who liked so much geometry, who saw the geometric representions of spaces at n dimentions she would be so pleased to studied John Nash's work... as much as stutied Galois' work! Thanks for this explnanations!

[@n124lp]

Thanks for a very interesting presentation. It's rather amazing that I or anyone else with a computer and Internet connection can "attend" presentations at the Royal Institution. It is unusual to see a presentation by a distinguished mathematician that intertwines mathematical information with a human story. Had you asked me yesterday, whether I thought that was a good idea, I would have said no, concentrate on the math. Having seen this presentation has fundamentally changed my mind.

[@alexvernes9264]

[@Research0digo]

A5:59 The best atlas to globe model was envisioned and proved by Buckminster Fuller. Instead of showing Antarctica spreading across the bottom of a map, he has it and all the other continents accurately shown, by merely making the breaks in the flat map where the various oceans and seas are. Keeping his theme of 'dymaxion-everything', he dubs his atlas to globe invention his Dymaxion projection. :)

[@LivingLatexKali]

One thing I would point out is that there *are*, after a fashion, "particles" of temperature, namely phonons. The phononic field even serves as a good model of the higher-order fields to the degree that you can create phononic singularities that precisely model the predicted behaviour of gravitic singularities.

[@scin3759]

Very impressive description of how some mathematicians prove big theorems. Break the problem into smaller problems and seek the help of experts in different fields. Obviously that necessitates knowing a network of experts. If all mathematicians worked that way, there would be even more impressive results than there are. This is something every young mathematician should be told early on.

[@robertschlesinger1342]

Very interesting, informative, and worthwhile video. A must see for all interested in the history of mathematics.

[@ishi92]

so well explained. That was a joy to experience! Thanks Cedric!

[@robertj.simpson354]

Good point about facing Mecca or any locale; one cannot simply use a straight line connecting one's current locarion with Mecca by using a flat map (usually a Mercator map), rather one must use the map's coordinate system of longitude and latitude to determine the true direction. Yet the length of the line pointing from one's current location to Mecca, even when Earth's coordinate system is duely implemented, may not represent the shortest distance to Mecca since the very opposite direction, a 180 degree turn, may accurately connect one's locale to Mecca along the shortest distance in the right direction, the direction similarly corrected for longitude and latitude coordinates. Calgary and Toronto (Canada) are almost equidistant to London England, but you'd be tempted to think that Calgary would be a couple thousand kilometers more distant while looking at the two Canadian cities in relation to London using a Mercator map, if not considering Earth's coordinates that suitably adjusts for the planet's sphericity. Similarly, the true shortest straight line distance between certain locations on Antarctic with Mecca will require the navigator plotting this to draw a line that actually runs off the side of a Mercator map to reappear on the other side of the map.

This is some next level of mathematical exposition! 👏💯🧠

[@dustinsc2023]

I loved the in depth explanation of partial differential equations as well as the different explanations of the formulas, and the geometry of visualizing the extra dimensions. I also loved that Nash did not like the movie since it got so many things wrong, but in a way math is like magic, mysterious and wonderful, as if peering through the mind of god or being able to communicate with the creator, yet at the same time being in awe and wonder as to how it is done.

[@hantzu1675]

JFN was asked about the film during a Q&A and he didn't criticize it. He just referred to fact that it had won Oscars etc. I suspect he was being diplomatic.

Cédric Villani is brilliant. He looks like someone who loves adventures. In 18xx or 17xx he would be someone like DaVinci, Edison or some other great inventor, maybe on a ship on the ocean searching for something that has never been found by anyone. A very very intelligent person. Btw, during my research on game theory for so many years I had the vision/idea (because of your gemetry stuff) about a multidimensional cube with payoff-tables, changing its sides based on changing payoff scenarios. A fast rotating cube, always changing its side always searching for the best fitting strategy. Nash has always something to do with geometry I really don't know why his work is somewhat inspiring.

I'm not bothered by showing equations on the screen - apparently unlike most people [I don't REALLY believe that it's "death" to show equations in a book or at a talk, anyway.] So, I very much enjoyed his talk, and would like to know more about John Nash.

HELLO, CEDRIC, On contemplating your words, I thought. It's true my prior reference to transcendental numbers relies upon the smoothness or crooked edginess of their expansion. What is helpful is to study and analyze the Complete Mathematical Works of George Saliba. Also helpful is to study the Foundations of Geometry as understood by the Writings of Islam Abdou Abdou of Egypt. I encourage you in this.
