## Quantum Mechanics

###### Temporal evolution of a wave packet in an infinite square well. This animated plot shows the probability of finding a particle as a function of position inside the well. At *t=0*, the wave packect has width *a/10* (where *a* is the size of the well), and is localized at the center of the well. The wave packet has no net momentum *p*, thus, the center of the wave packet does not move. However, since we know the approximate position of the packet at *t=0*, by the uncertainty principle, there must be a spread in the momentum. Thus the packet spreads out, although it eventually reforms. (This is known in the lingo as "collapse and revival.")
