factual, for it does not describe observed facts and contains no immediate counterpart of these facts. Yet there is a strict correspondence between the sequences of facts and the end-product of the unitary evolution of wave-functions of composite systems, since these wave-functions provide us with information about the probability of facts and also about the mutual dependence of (or correlation between) the facts. As a consequence of this accepted dissociation between facts and representation, any motivation to modify the representation each time an experimental outcome is obtained disappears. No intrusion of fact-like discontinuities into the wave-mechanical representation is needed; nothing like collapse of the wave function is required. One has only to find the proper translation scheme, or empirical correspondence rules, between the representation and the (sequences of) facts." /> Complemetarity, representation and facts - Bitbol Michel | sdvig press
