贝尔定理：量子维恩图悖论

MinutePhysics, with 3Blue1Brown, explains Bell's theorem using a Venn diagram paradox and polarizing filters. It shows why no local hidden variable theory can reproduce quantum correlations.

Why HN likes it: Repeatedly recommended as the most accessible explanation of Bell's inequality, reducing it to a simple counting problem.

“did a two part collab that simplifies some of it down to a counting problem that'd be suitable for grade school.”
