Weak Measurements and Determinism

Click For Summary
SUMMARY

This discussion centers on the implications of weak measurements in quantum mechanics, specifically regarding the determinism of events. It posits that if the position and velocity of a particle can be identified through weak measurements, then the future evolution of that particle is theoretically deterministic. The conversation suggests that this determinism may extend to all micro and macro events, challenging the perception of randomness in quantum mechanics. The role of weak measurements in understanding these concepts is emphasized as underappreciated.

PREREQUISITES

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.
