Weak Measurements and Determinism

  1. Dec 5, 2009 #1
    Just a thought:
    If we could identify the position and velocity (via weak measurements) of a particle at some instant, and its future evolution is fully determined (at least in principle, not in practice), then can we extrapolate this to surmise that all events are are inherently deterministic? If true, then can we say all micro events are deterministic? And therefore all events (macro scale included) are determined in principle? Is not enough credit given to weak measurements?

    A weak measurement does not reveal a property of a single particle, but of an ensemble of particles. I hope it answers your questions.
