I love Edward. Thanks for having him back on. He has the mindset that most esoteric subjects in math, like what a local system is, or a Drinfeld module, can be explained simply. I think this is a fantastic frame and a necessary precondition to indeed explain simply ;).
In the Harvard math dept (where Ed was a Harvard Society of Fellows... Fellow) there is a "Basic Notions" seminar, in which professors tell grad students about something they now consider a basic notion. Many years ago Ed gave one on "the geometric Langlands correspondence". He was not 100% convincing that this is a _basic_ notion, but he came closer than I would've expected.
What a brilliant way to concretely elucidate an esoteric topic. He teaches it in a way a bright child could understand, with an unbridled and infectious enthusiasm. 10/10
Frenkel is an extraordinary communicator and a joy to listen to. His passion for the material really comes through and you can feel that it's rubbing off on Brady.
Watched the beginning of the Abel Prize lecture about Langlands just to realize the amazing effort that Brady is putting into the graphics. Here in this video, the graphics is so complimentary to the story. Wonderful work.
What always surprises me most is how spot-on Brady is in all of his work. I've been called knowledgeable over a wide variety of fields myself, but I don't think I've ever been quite *that* incisive. For example the idea that there might be other kinds of correspondencies/homomorphisms/functors between fields of mathematics really *did* have to be put in, while I would have missed that one, evenwhile being reasonably well educated and interested in math myself. Obviously I'll be combing through Edward's book forthwith, and an hour-long with a mathematician (also a pedagogue) of his pedigree is always a treat. But since these videos are about science education and outreach, as an ardent follower, I think Brady's role in getting the thing done might be a bit understated.
I was only watching Professor Frenkel's video on the Reimann Zeta Function the other day! I'm happy to see a documentary-length video with him as the subject matter expert!
Edward Frenkel can explain the most complex mathematical ideas in the simplest possible way which can be understood by anybody. This is a sign of highest inteligence not seen very often even among smartest people. And let's think for a moment that he does it in a language foreign to him. Which he started to use only as an adult.
I have two points to mention... 1. I find it mesmerising that Prof. Frenkel is able to not only make eye contact with Brady but also to stare directly into his camera lens to truly connect with the audience at large... a masterclass indeed! 2. I saw the BBC Horizon documentary on Wiles' feat (circa 1993) and the visuals have always struck me... a cross between a facetted torus and a weird cathedral-esque 4-d pan of columns... this always confused me yet I see now, thanks to Prof. Frenkel's simple description of what an elliptic curve and a modular form really is, that it is really so simple a concept to grasp (an example of how, sometimes, a popular documentary using flashy imagery can be misleading(?)) Thankyou for this indepth exploration... I've learned soooooo many things🥰
Are we not going to appreciate how he effortlessly slid his books into the conversation? Apart from being a mathematical genius, he's also a marketing genius.
Brady, I love these long form videos with great communicators. (Ed’s chat about string theory immediately comes to mind). Also, while speaking about great communicators, I appreciate YOU so much for the questions and insights you have. So many times you blurt out the exact thing that I am thinking! So long story short, thank you for all you do!
The hour-long Numberphile deep-dives are rare, but also really nice when they come out. I think the rarity makes it even better, as it means I'm really going to sit here and just listen along for the whole thing rather than hop around between 2 or 3 of them.
omg I read Dr. Frenkel's book "Love and Math" a few years ago!! it's one of my favorites, he has an incredible life story. So cool getting to hear him discuss the langland program!
For a basic overview of what "representations of Galois groups" means, I'll break it up into the two parts. Galois groups, and representations. Galois groups are the groups of symmetries of field extensions. That is, if you have one field contained in another field (fields basically being nice systems of number-like things with all the nice properties), the Galois group tells you all the symmetries (automorphisms) of this field extension; all the ways you can transform the bigger field in a way that keeps the smaller field completely fixed, but also where the larger field retains exactly the same structure. The simplest example of this that everyone will be able to understand is the Galois group of the complex numbers over the real numbers. There is the trivial "identity" automorphism; you just keep every complex number the same. Then there is also complex conjugation: you can swap i and -i, and swap all the other complex numbers accordingly, and the complex numbers will behave exactly the same (the structure is preserved). And furthermore, this doesn't affect the real numbers at all; they are fixed under complex conjugation. It turns out that these are the only possibilities. These symmetries form one of the most trivial groups, called Z/2Z or C2; the cyclic group of order 2. So the Galois group of the field extension of C over R is isomorphic to Z/2Z. Representations of groups are, as the name suggests, ways that you can represent the structure of a group. Specifically, it's the ways that the structure can be represented in terms of linear algebra. At a very basic level, we are looking for all the different and interesting ways that we can choose a vector space, and a set of linear transformations (matrices, basically), so that each element of the group is associated with a linear transformation, and the linear transformations interact in the same way that the elements of the group interact. It's a little bit more than that though, because there are endless ways you can make the vector space way bigger than it needs to be for the given group. So really it's more interesting to ask about irreducible representations; ones where all of the dimensions of the vector space are inseparably mixed together by the group's representation, and so it can't be split into two smaller representations acting independently. It turns out that the complete list of irreducible representations is extremely interesting; if you just look at the traces of all of the linear transformations (gathering up linear transformations that come from the same conjugacy class of the group, which are basically the same as each other but viewed in a different basis, so have the same trace), you get a table of numbers with conjugacy classes in one direction and irreducible representations in the other, called the character table, that has amazing properties. Firstly it's square; there are exactly as many irreducible representations as there are conjugacy classes in the group. Secondly, with the correct weighting by size of conjugacy classes, this table's rows and columns are all orthogonal to eath other. That's just the beginning; there are so many cool things about the character table, but I digress. A simple but nontrivial example might be the symmetric group S3. It has 6 elements, usually described as the permutations of 3 symbols. These are collected into 3 conjugacy classes; a class with just the identity, the class of transpositions (2-cycles), of which there are 3, and the class of 3-cycles, of which there are 2. There are also, of course, 3 irreducible representations. There's the 1D trivial representation, where every group element is mapped to the 1D identity transformation (1). There's the, again 1D, sign representation, where every even permutation (identity and the 3-cycles) is mapped to 1, and every odd permutation (the 2-cycles) is mapped to -1. And finally there's the 2D representation that corresponds to the symmetries of an equilateral triangle in 2D space, where the identity maps to the identity, the 2-cycles correspond to the 3 reflectional symmetries, and the 3-cycles correspond to the clockwise and anticlockwise rotational symmetries. The character table in this case is quite simple, so it won't look so interesting. But you can look up the Schur orthogonality relations, and check them for yourself.
I thought I will watch the first few minutes and tune out. I almost did not blink for an hour, and I would've listened to him for another hour. Amazing topic.
What I like of professor Frenkel is that he is not only presenting his story to Brady, but is actually seeking contact with us, the viewers by looking at the camera i.s.o. only Brady.
Beside his extraordinary explanation on Langlands Program, I studied mathematical education and was stunned by how he introduced the idea of number and negativity using floss, and of course topology as well.
An one hour? Tho, I guess, technically, based off of standard English rules of thumb, you would put AN before _one_ (because it starts with a vowel) vs using A before _one,_ just because it _pronounces_ like "wun".
I am myself mathematician (from Paris) and I am happy to discover how enthusiastic was Edward Frenkel when he speaks his magic mathematics. I am going to buy his book and I hope to understand better from him, because he is also very pedagogic ! True chance for his colleagues to have him with them ! Last thing, I remember Edward Witten (another Edward !), who proves that the "Geometric Langland program" can be interpreted as a Mirror Symmetry, ..., Electrifying !
Professor Frenkel always has something interesting and then presents it with great enthusiasm. Excellent... and I now have to go back to Ken Ribet's video!
i forgot where i heard this, maybe another numberphile video, but the math guy said "there is a life before and after knowing about generating functions" because they are that powerful.
Thanks for having Dr. Frenkel back again. It was interesting learning about the correspondence between elliptic curves and modular forms with a detailed example. Would love to see more videos like this!
The most exciting thing in Mathematics, explained by the best mathematics explainer on the planet. Absolutely brilliant, Numberphile hits another home run. Thank you thank you thank you!
You know, I was just thinking a week ago when this guy would return. I loved his video about the whole -1/12 controversy - really put it in a new light for me.
I would love to see a similar Numberphile video on Curry-Howard isomorphism (correspondence between logic and type theory) or Homotopy Type Theory (correspondence between topology and type theory/category theory).
I don't know what any of those are but I'd love to see more examples of such correspondence to grasp the broader idea better. Thanks for mentioning these, I'm going to try and read up!
Many thanks for such a fascinating in depth introduction to the Langland's program. Edward's enthusiasm is contagious. Can't wait for the next instalment!
I'm not even an amateur in math, just wrote a couple heuristic algorithms for a modified TSP problem and that was my limit. But this video was fascinating and inspirational.
Fantastic! Really the first time I could have such a deep understanding of this fascinating Langland's programme! Thanks for doing this video, and of course to the brilliant Edward Frenkel, and giving the required time to make us understand! Please continue doing this on this fascinating programme, or similar math mysteries! I think that 100k views in 3 days is just the sign that the public is also catching on this and wants to know! This is so important to make maths being understood to as many people as possible, as it is so impossible to grasp such level of maths for so many people, even with some years of maths in college, as compared to physics where people can really catch up much more easily with things, because of our general intuitive grasp with real things around us.
I love Dr. Frenkel. I got his autobiography novel over 10 years ago thanks to Numberphile and it got me motivated to go back to school and get my graduate degree. I read his book, got inspired, started to self learn, and then enrolled when I realized my mind was still able to enjoy the whole process of learning difficult topics and theorems to solve complex problems. Whoever is fimling this, please stop zooming in, panning to erronous locations, auto focus/zoom harshly, because it looks like a POV of the blair witch project or an amateur adult film.
Thanks for giving this an hour! Edward is one of my favourite speakers. Having some grasp of the Fermat proof is on my bucket list, and this takes me a couple of steps closer, esp in the elliptic curve/modular forms correspondence.
This is the first video I’ve seen from this presenter, but it’s clear that he knows (perhaps loves) the subject and has a clear way of explaining it so that I feel like I’m grasping it. Edit: And I kind of love that house that he’s in. Perhaps an A-frame.
I had a high school math teacher who was a great mathematician but a terrible, terrible teacher. The guy in the video is just the best, a famous mathematician who is also a fantastic teacher. Wish these kind of people were more common! (They're super common on Numberphile of course, but harder to find in the wild)
The alien melody from Spielberg's/Williams's "Close encounters of the third kind" in the fragment about harmonic analysis... instantly recognized it, the movie is so deeply engraved in my memory...
I love Frenkel. at 40:12 Bless his heart for thinking a non-mathematician will enjoy reading about elliptic curves, even if it is Ash & Gross's treatment.
Wow! Super dense, but super informative. This is the first time I’ve really understood generating functions, and that was only from the first 15 minutes of the video! 😂
How on Earth did those three mathematicians come up with that harmonic series? It feels like magic that it "just works" for that counting function. I'd also be interested to hear whether Professor Frenkel thinks Riemann might be solved in this way by translating it to some other domain of mathematics and treating it as a different problem?
I think the series came out of the definition of the generating function, though not sure where the 11,22,33 etc come from! Let’s clear it up in part 2!
How one man can have so much knowledge in his head - and this is most likely not even a percentage of his total mathematical knowledge is just.... wow!
To stay that composed whilst jumping from one methodology to next and having the wherewithal to give tangible examples I could understand without having to rewind - I doff my hat to you Sir. Am also assuming that was one take 😮
For "tunnels below surface", look closer at continued fractions, especially in the Stern-Brocot context which provides exact arithmetic visioned by Gosper. I conjecture that the elementary proof of FLT can be found there.;)
these long, detailed numberphile videos are rare but they're always the best
This is the longest numberphile video, so it's very rare
Edging is better than instancy
Assuming an average duration of ten minutes, with std dev of five minutes, the chance of a video longer than one hour is nearly zero!

I'd also be interested to hear whether Professor Frenkel thinks Riemann might be solved in this way by translating it to some other domain of mathematics and treating it as a different problem?
Agreed (with first point), I'd like to see an explanation as to how that series was arrived at.
I think the series came out of the definition of the generating function, though not sure where the 11,22,33 etc come from! Let’s clear it up in part 2!
How one man can have so much knowledge in his head - and this is most likely not even a percentage of his total mathematical knowledge is just.... wow!
I like the fact that after so many years finally this topic is getting popular!
More of these long form vids please. : ). That was cool
Dr. Frenkel's long-awaited return!
This is hands down one of my favorite Numberphile videos
What a beautiful episode!
his eyes shine so bright I need a sun blocker
Best video of the Langlands Programme!
To stay that composed whilst jumping from one methodology to next and having the wherewithal to give tangible examples I could understand without having to rewind - I doff my hat to you Sir.
Am also assuming that was one take 😮
Professor Frenkel is incredible to listen to
Closing the curtains and putting on the projector for this one.
For "tunnels below surface", look closer at continued fractions, especially in the Stern-Brocot context which provides exact arithmetic visioned by Gosper. I conjecture that the elementary proof of FLT can be found there.;)
