I mean : Suppose we have got a problem, that can be stated as a (set of) binary proposition(s) P(i)....(e.g. "The laws of nature are local","The speed of the particle is v") Then, obviously the phycisist's job is to answer "yes" or "no" (by extension to find the velocity)....but since quantum physics is quantum, the lazy man answer could be, and it's then always true !! : It's a superposition of "yes" and "no".... So why bother trying to answer, when quantum logic always knows : Maybe you just have to find the relative coefficients of the superposed states. (Don't bother to give an answer, it's useless) ??
