As limestone, calcium carbonate is a biogenic rock, and is more compacted than chalk. As marble, calcium carbonate is a coarse-crystalline, metamorphic rock, which is formed when chalk or limestone is recrystallised under conditions of high temperature and pressure.
Definition: A wavefunction is a function describing the probability of a particle's quantum state as a function of position, momentum, time, and/or spin. Wavefunctions are commonly denoted by the variable Ï.
Wave function collapse means the same thing in quantum mechanics as it does in classical statistical mechanics. I see a lot of misleading answers to this question. Most have some validity, but I think in one way or another, they miss the point. The most important thing to realize about wave function collapse is that it's not specific to quantum mechanics. The history is that in 1931, Koopman and Weil discovered a way of reformulating classical statistical mechanics in terms of a complex Hilbert space of wave functions.
