Pure mathematics Videos Recommended on Hacker News (97)

Pure mathematics is one of the 150 topics Hacker News readers organize their video recommendations around. These 97 videos each earned real recommendations in real HN threads between 2010 and 2026 — 412 recommendations in total — and they're ranked by how many separate months the community kept coming back to them, not by view count.

Pure mathematics: algebra, group theory, number theory, topology, analysis, geometry, calculus, linear algebra, Euler, prime numbers, Riemann hypothesis, mathematical proofs, famous theorems.

Why HN keeps sending people here — on Vectors | Chapter 1, Essence of linear algebra: “the most welcoming and informative introduction to the topic I've ever seen” — an HN commenter, 2018.
