    To really comprehend how sick his achievement was, consider this: Andrew Wiles, the already extremely smart guy that proved Fermat's last theorem, spent 7 years trying to prove it using loads of techniques and concepts that had been developed in the 20th century. Ramanujan on the other hand lived in the beginning of the 20th century, so he had independently invented some of those very same concepts himself, and already tried using them in his proof!!! This means he was on the right track, and considering these where scribles he made in a notebook during travels he made, he clearly wasn't investing nearly as much time into proving it as Wiles while at the same time having the disadvantage that he had to come up with stuff that was already well established in Wiles time. It's like someone from ancient Greece who knows absolutely no calculus(cause it wasn't developed) and only has a solid background in classic geometry coming close to proving advanced theorems in calculus by individually developing a large part of the machinery of the subject that took hundreds of years and a lot of people to develop! That's just completely insane and of the charts, and what I would imagine only a highly advanced alien with a much larger brain than a human to be able to do.

I really Dig Mathologer/Burkard's channel, and I especially liked his -1/12 vid. I'm glad someone finally mentioned him, and not surprising it was you, cause Matt is also a boss. Thanks for that, and another captivating video too, of course.

    That was a fantastically whirlwind trip tying together some seemingly remote threads! And it's especially poignant to realize that Ramanujan might well have proven FLT decades before it was actually done. I particularly liked the "near-miss" treatment of FLT solution attempts, because that's the way I've always looked at Pell's equation - no (non-zero) square can equal n times another, if n is a (positive) non-square (e.g., Euclid's proof that √2 is irrational); - but you can always find numbers that "miss by 1" - - and that is Pell's equation! p² = nq² + 1 . . as well as what might be called, the associated Pell's equation p² = nq² - 1 which has solutions for infinitely many n's, but none for infinitely many other n's.

    Matt, you and Ramanujan really are quite similar. His search for near misses regarding Fermat's Last Theorem reminds me very much of the Parker Square. But on a serious note, this is a great video and I'm going to check out all of the information you've linked us in the description now.

    Thank you Matt for another great video and an interesting challenge problem. I thought that my process might be interesting. After one mistaken attempt, I was able to solve A^4 + B^4 = 635,318,657 in three tries. 1) For A^3 + B^3 = 1729, the sum is just one more that a cube. I hoped that one A would be a low single-digit. Knowing that our nine-digit target begins with 63 (almost 64), and remembering that the leading digits of powers of 2 are themselves close approximations of powers of 2 that are 1/1024 as large, I thought that one B could be close to 2 times a power of 10. Wrong! 635,318,657 ~ 2^6 x 10^7, the fourth root of which will NOT yield my hoped-for result. 2) What if A and B were approximately equal? Then A and B might be close to (635,318,657 / 2) ^ 1/4 ~ 133.5. Choose the integer part for A. Solution 1: A = 133 and B = 134! 3) What if the difference between A and B was the greatest? The fourth root of 635,318,657 is about 158.8; again choose A by selecting the integer part. Solution 2: A = 158 and B = 59! Luckily, my method led me to the solutions. This "least and greatest difference - integer part" strategy also works with 1729. Would it also work for the lowest number that is the sum of two squares in two different ways? For 65, the "greatest" portion yields A = 8, which is approximately the square root of 65 ~ 8.06, but "least"-wise would give us a guess of A = 5, as (65/2)^1/2 ~ 5.7. The second solution is instead A = 4, B = 7. Often times, however, for A^2 + B^2 = N, the "least difference" method, A ~ (N/2)^1/2, will give you a good first approximation, with the solution being near by. Keep up the good work!

    It appears that Ramanugan might have cracked Fermat theorem had he lived another 20 years. That was an incredibly difficult proof and we should remember that Wiles needed help in the end. I think Galois theory should be introduced in high school, after all Galois had very little education, his name is on the first page of Wiles’ proof of Fermat

    No, Ramanujan was an actual mathematician, and a great one at that. Not someone who had just memorised a few algorithms to multiply numbers, which I'm sure is hard, but not quite on the level of Ramanujan. The fact that he could visualise numbers was just an added bonus.

    Thanks for talking about the generating functions Matt. The way people usually tell the 1729 story, like he invented it out of thin air, seems misleading. I also believe this fact about 1729 was recorded in the notebooks years before the Taxi-Cab incident. I forget the exact page, but I think its on a page that also contains a geometrical problem (This narrows it down a lot since Ramanujan did so little geometry in his notebooks).
