Bell's Theorem Clearly Explained | Quantum Theory

This is a detailed explanation of Bell's Theorem, including how John Bell arrived at his theorem, what his precise assumptions were, and the deep significance this result has had for the Foundations of Physics. This is the tenth video in my Quantum Theory Playlist.
