Bell's Theorem: The Quantum Venn Diagram Paradox
An 18-minute video by minutephysics about quantum foundations and probability and statistics, on the Physics shelf. It came up in 2 Reddit threads, in r/3Blue1Brown and r/AskPhysics. It is pitched at intermediate level.

Builds Bell’s theorem as a paradox involving probability sets and quantum correlations.
Study notes
Intermediate, Derivation. Step 6 of 6 in The physics under electronics
Helpful first
- Basic probability
- Sets and intersections
What it builds
- Derive a constraint from an ordinary shared-property model.
- Use Venn-diagram reasoning to expose assumptions.
- Compare the constraint with entangled-photon correlations.
Useful moments
- 6:28When removing a filter changes results
- 8:24The everyday superset inequality
- 9:25What entangled means here
Check yourself: Which assumption about shared properties makes the classical inequality follow?
