Bell’s Theorem and EPR

Bell’s Theorem and EPR

2019-03-2101:13:04

Zak and Derek discuss nothing less than the fundamental nature of reality. They start with the arguments made in the Einstein, Podolsky, and Rosen paper from 1935, which were then tackled by John Bell in 1964 with Bell’s Theorem and Bell inequalities.
