Why should quantum states be so hard to identify and describe? Heisenberg's uncertainty principle states that we cannot know a particles position and velocity at the same time.
But we can. It's just that if we prepare the particle in the same state again and measure we'll get different values and the more precisely we measure q the more scatter we get in the measure of p.

But nothing prevents us from describing where a particle WAS and how fast it was moving, 2 hours ago, just not right now, at the same time. If we throw away immediacy we have Heisenberg describing the world exactly-in the immediate and maybe the remote past. or whats a david deutsch for?
