If we ask, for instance, whether the position of the electron remains the same, we must say 'no'; if we ask whether the electron's position changes with time, we must say 'no'; if we ask whether the electron is at rest, we must say 'no'; if we ask whether it is in motion, we must say 'no'.
J. Robert OppenheimerBoth the man of science and the man of action live always at the edge of mystery, surrounded by it.
