From a deterministic point of view Shown below is a diagram of the Aspect experimental setup. 1 The Hidden Variable Theory says that nature is deterministic and, despite what may be predicted by Quantum Mechanics, particles always have a definite position. What happens to the photons which are produced in this experiment When a blue photon is produced at the source, if it travels to the left ...

Einstein's critique of Quantum Mechanics in the EPR paper was an attempt to show that Quantum Mechanics was somehow not complete. The argument indicates that, eventually, physicists will need to develope some new theory to describe nature. One way to escape from this critique is suppose that the quantum mechanical approach to describing nature is valid and the apparent incompleteness arises from ...

One of the first physicsts to be publically troubled by the philosophical interpretations of quantum mechanics was Albert Einstein. In 1935, he co-authored a paper which was intended to show that Quantum Mechanics could not be a complete theory of nature. The arguments in the EPR paper are very similar to ones which Einstein himself made in correspondences to friends, but are not exactly the ...
