  • This is a really beautiful proof that connects complex numbers and primes to derive a formula for calculating pi. It should only require high-school algebra prereqs. [VIDEO] If you want to truly follow the proof, there's one little bit on the chi function in there …

    In The Exterior Algebra and Central Notions in Mathematics (2015) [pdf]
  • 3Blue1Brown has been recommended on HN before ( [LINK] ) But it's so great I think it bears bringing up in case anyone reading this comment has missed it. This channel animates math proofs, shows you the intuition behind fields of math, and constructs subjects …

    In Physics Travel Guide: a tool that makes learning physics easier
  • This is a half hour 3Blue1Brown video: [VIDEO] If you're willing to watch at least the first half of it, I think it'll give you a very intuitive grounding for 1) why integers have unique polynomial representations, and 2) why that's related to (semi)prime factorization.
