Abstract
Since 1927, physicists with few exceptions (Einstein, Podolsky and Rosen; de Broglie; Landé) accepted the Copenhagen interpretation of the quantum formalism, due to Heisenberg, Bohr and Pauli. Since 1934 I opposed this. I contended that the quantum formalism in its statistical interpretation (Einstein, Born) had no special epistemological consequences; that it could, and should, be interpreted realistically (and, of course, locally); and that the so-called indeterminacy relations were just scatter relations; and that the so-called ‘collapse of the wave packet’ was something that occurred in any probabilistic theory and had nothing to do with Planck’s quantum h and even less with an action at a distance. I now submit a new variant of the EPR experiment that can decide between a realistic interpretation and Copenhagen.
