Fundamental physics Videos Recommended on Hacker News (164)

Fundamental physics is one of the 150 topics Hacker News readers organize their video recommendations around. These 164 videos each earned real recommendations in real HN threads between 2009 and 2026 — 390 recommendations in total — and they're ranked by how many separate months the community kept coming back to them, not by view count.

Physics: classical mechanics, relativity, thermodynamics, electromagnetism, Feynman lectures, physical law, physics courses, Walter Lewin, Veritasium, physics explainers and demonstrations.

Why HN keeps sending people here — on I bought 1000 meters of wire to settle a physics debate: “Yeah I really liked the AlphaPheonix video[0] where he actually built the thing in a field and explained the entire effect properly.” — an HN commenter, 2023.
