物理学中被误解最深的概念

Veritasium's explainer on entropy, presented as one of physics' most important and least understood concepts. It uses examples such as heat engines and the sun's energy flowing through the Earth.

Why HN likes it: HN commenters say it made entropy intuition click and point to it in threads on energy, heat and equilibrium.

“This veritasium video explained it in a way that finally clicked for me”
