Please provide brief answers to the following:
1) In the famous EPR paper, the authors do not attempt to define reality, rather they give a minimal criterion which they consider a "reasonable" requirement of reality. (See 4th paragraph of EPR paper). Explain, in your own words, what the EPR criterion for reality is. How is this criterion expressed in Nick Herberts's hypothetical Bohr-Einstein conversation?
2) Bell's theorem involves predictions about polarization correlations (PC) in an EPR type experiment. The actual data for such an experiment is basically a list of pairs of results from two detectors like those shown on pg. 218. Construct three such lists, with 10 measurements per list, for the cases when PC = 0, 1, and 1/2. (Note that the data for either detector should always show an equal distribution of U and D measurements).
3) Clauser carried out the first actual EPR-type experiment, the results of which demonstrated a clear violation of the Bell inequality (thus apparently invalidating purely local models of reality). However, the Clauser experiment is considered to have a loophole. What is this experimental "loophole" and how did the later experiments of Aspect et al. get around it?
Everyone also needs to send me a specific question you had about the reading.
