Hitch-Hiker's Guide to Bell's Theorem

When Bell began working on his now famous inequality his goal was to determine the consequences of any local hidden variable theory, like that proposed by Einstein, Poldosky, and Rosen in 1935. The results of Bells work shook the foundations of the realist perspective of Quantum Mechanics, and had dramatic philosophical consequences on the debate over the goals and purpose of science. Many argue that Bells theorem is not only one of the most important discoveries in Modern Quantum Mechanics, but because of its extensive ramifications on the way we MUST look at Quantum Mechanics, it is also one of the most important in terms of the philosophy and direction of science.
