... Other scientists were much more ready than Einstein to modify the classical 19th century view of determinism. A new theory, called quantum mechanics, was put forward by Heisenberg, the Austrian, Erwin Schroedinger, and the British physicist, Paul Dirac. Dirac was my predecessor but one, as the Lucas ...

... Standard quantum mechanics presupposes the existence of an externally defined classical variable called t. The other variables, x play a very different role and are represented by operators. This is clearly an approximation that requires the existence of a classical clock external to the system, and ...
