Recreational & visual math is one of the 150 topics Hacker News readers organize their video recommendations around. These 141 videos each earned real recommendations in real HN threads between 2010 and 2026 — 552 recommendations in total — and they're ranked by how many separate months the community kept coming back to them, not by view count.

Math explainers and recreation: 3Blue1Brown, Numberphile, Mathologer, puzzles, fractals, surreal numbers, math history, mathematicians, beautiful proofs, math in everyday life.

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.
