How/when does quantum mechanics become classical mechanics?
Can you give me an example of a system where we can see the transition from quantum mechanics to classical mechanics?
One example is the double-slit experiment where electrons, which exhibit quantum behavior, are fired at a screen with two slits. On the other side of the screen, the electrons form an interference pattern, which is a quantum effect. However, if we gradually increase the size of the particles or decrease the distance between the slits, the interference pattern disappears, and we see classical behavior, like a straight-line trajectory.
