Heisenberg Uncertainty Principle?
When physicists say there is a so-and-so chance that a particle is in a particular place, do they mean…
1) that the particle has an exact location, but the best they can do with their crude measurements is to calculate the chance that it is in any place in particular
2) that the particle’s position is literally a fuzzy zone of chance with no absolute position
3) something else?
This also (of course) applies for speed, but I don’t want to confuse things…
