Hanson in Quanta & Reality v. 86 Von Neumann advanced a ‘proof’ that it would be impossible to reinstate a classical determinism in microphysics; it was logically pointless to look for ‘hidden variables’ underlying quantum processes. 1971Nature 24 Dec. 433/2 Research in Britain concentrates on the fundamental microphysics of fogs.
