Causal Particle Trajectories and the Interpretation of Quantum Mechanics

The fundamental disagreement between Bohr and Einstein at the 1927 Solvay conferences concerned not only the interpretation of quantum mechanics but also general philosophical orientations as to the nature of physical theory. Although these two aspects of the debate can never be fully separated, it is clear that, since quantum mechanics is after all a theory about the behaviour of matter, specific claims of the various interpretations can be more or less adequate in the face of experimental evidence, and even shown to be false in certain cases ¹ , ² .
