p. 775. Togethernesslocked

  • John Polkinghorne


‘Togetherness’ reviews Einstein's thought experiments, each of which purported in some way to circumvent the limitations of the Heisenberg uncertainty principle, and Niels Bohr's success in showing that application of quantum ideas to all aspects of the proposed experiments resulted in the uncertainty principle surviving unscathed. With Boris Podolsky and Nathan Rosen, Einstein continued to argue that there must be something incomplete in conventional quantum theory. It failed to account for what he believed must be definite values of spin components. The EPR effect — togetherness-in-separation — and the work of John Bell, and later Alain Aspect, that vindicated the predictions of quantum theory are then discussed.
