Edit: 31:00 This resonates with me a lot, I have asked myself many times with Galois Theory why anything shown was thought of, or how any of it follows from the axioms. Most of what I've seen was either too vague to actually show the specifics, or too technical to clearly explain the underlying material, so you're doing a great service by laying this out fully.

I had an interesting career in ASIC and DSP design, in one chip it was based on Galois fields and Golay error correction, another was based on the Fast Wavelet Transform with DCT inside and an FFT engine, another was more mundane, building a pattern waveform generator based on sine waves but not using a high resolution Sin ROM, instead computing Sin from low resolution Sin and Cos. Math and ASIC design is a special pairing made in heaven, lots of flexibility to produce the desired result, it's my favourite type of chip design, no arguments about architecture, the math defines tjhe that. Do I remember much about Galois fields, nope, not a darn thing.

Very well explained introduction to a fascinating but quite opaque subject! Great work! I am keenly looking forward to follow-up videos. What you say in the final segment is very true. In particular the Bourbaki collective has killed the human and historical element in teaching mathematics and the tone they set has made modern mathematics somewhat cleaner perhaps but much more difficult, and unnecessarily difficult, to learn. Therefore, pedagogical videos like yours, which teach mathematics in a language and from a perspective more suited to the human brain, are very important. You could improve the audio quite a bit by suppressing reflections in the room you are recording in. It sounds very echoey. (Not like the echo in a large hall or outside, but lots of very fast reflections from nearby surfaces. This is one of the main reasons for bad quality of voice recordings and it becomes very obvious once you hear examples with and without those reflections.)

@@martintrifonov AFAIK Bourbaki did important work in cleaning up the foundations of algebraic geometry, which had previously gotten into quite a mess and even produced some wrong results due to a lack of rigor. The Bourbaki books were great as an underlying structure but their huge success had a detrimental effect on the pedagogy of mathematics in my opinion, and not only in my opinion, as you can read in the Wikipedia entry: >>As Cartier remarked, "The misunderstanding was that many people thought it should be taught the way it was written in the books. You can think of the first books of Bourbaki as an encyclopedia of mathematics... If you consider it as a textbook, it's a disaster."

Nice vfx. You have screen recorded a digital art program. I can see the artifacts of the pressure sensitivity graph in the writing. I think the canvas in the video is a 3D asset, but you could have placed it and distorted it with a perspective grid. You are using a soft brush that adds up on overlaps making it look very realistic as if the liquid collected. What blending mode are you using? Is it just opacity? I am guessing you have some textures here and there or some glossy shading applied to the 3D canvas. It looked very good, I might have to steal some of your methods. The editing where the pacing of the sped up writing following you sentences was very good. Sometimes it was in parallel, but that’s what you gotta do no? I think I will use motion graphics with custom typography with this kind of pacing. It is taking a long time to develop, especially when I want to continue to multiply my tasks with pairings between glyphs and innovative characters and transitions, but hey it could become a big animated typeface for math with special dynamic customizable characters! I don’t have much experience with coding so many variables though, but I am beginning to design a custom encoding and variable axes for it… just pseudo code at this point
@martintrifonov5 ай бұрын
Nice detective work :) ! Pretty close, a few things I did a bit different. I didn't screen-record the whiteboard, rather I just made drawings on my Remarkable (E-book type) tablet. I downloaded the drawing files from the tablet to my computer, and I wrote a little code that reconstructs the paths of the lines and animates them. The drawing is reconstructed from the paths using the p5js and p5brush libraries. The latter, p5brush, creates realistic looking brush strokes. And yes, from there on you are mostly correct - some shading and composition! The editing (speeding up the pace of the drawing) was rather labor-intensive. I'm thinking this could be automated a bit in the future. Interesting, what you're describing about a dynamic animated math typeface - but I'm not sure I follow completely. Could you elaborate a bit on what this project is?

It's a fair question! It is a symmetric polynomial, yes - and you're right to say that we can't learn how to represent it using using only elementary symmetric polynomials by the argument in the first proof. The first proof only shows how to represent power sum polynomials (x^k+y^k+z^k) using elemetnary symmetric polynomials. However, the second proof in the video shows how to do this with any symmetric polynomial, including your example. Hope that makes sense!

If we are given a polynomial of degree 3, with roots a,b,c... can we compute something like sqrt(a) + sqrt(b) + sqrt(c)? Also, can we make use of computing symmetric expressions to give us good starting points for polynomial root finding algorithms or modify the iteration steps in one? I'm imagining for example... unlikely scenario but, if you knew for example that your given polynomial has only real roots, and one root is particularly larger than the others, you could approximate that large root by computing (r1^50 + r2^50 + ... + r_n^50)^(1/50).

@@martintrifonov Looking at this again with fresher eyes, at least for the first question I asked I think the sums of powers of roots can be applied to taylor series. For sqrt(x) a taylor series centered at x=1 converges if x is in [0,2]. If we only have real, positive roots we could compute sqrt(r1) + sqrt(r2) + ... + sqrt(r_n) by squishing the roots closer to the origin by substituting cx for x in our starting polynomial, where we can pick a constant c. After computing the taylor series to an accuracy we like, we can multiply the sum of those approximations by sqrt(c) to get the final answer. It should be relatively straightforward to determine the largest magnitude a root might have and pick c to be that largest magnitude.

I had the same obstruction for the Galois theory : too much theory to learn before solving any equation....it is the same than a promise for a good dessert but you have to eat a lot of heavy dishes ;-) For me Lagrangian resolvents was the point I stopped, because despite I understand the main ideas (splitting fields and so on, .... more in the group theory and fields) the difficulty is to guess whether a given equation is Galois solvable and how to process in that case. There is an unknown too : can you apply the theory when the coefficients ARE NOT rationals (not integer).. is this for "algebraic equations" only ? Guessing the resolvents (or the intermediary fields) is the extra I need ....the new entries in your "bag".
