This statement does not hold if velocity at time zero is known and the time of interest is the past.
This statement does not hold if velocity at time zero is known and the time of interest is the past. It is illustrated by a thought experiment involving a gamma-ray microscope, in which a photon and electron collide. A corollary to this statement involves (*) energy and time, and one side of this inequality is h bar over two. For 10 points, give this statement that there is a minimum product of the inaccuracies of measuring a particle's momentum and position, which is named after a German physicist.
