Quantum Mechanics treats familiar situations as if they were occupied by waves instead of familiar particles. This treatment can solve many problems that classical physics lacks the depth for. Exploring new ways of defining all of our previous concepts of physics in terms of waves leads us to also consider brand new properties that evolve from waves that particles do not have. One example of such a property is revival. A point particle has a definite position and moment while a wave exists everywhere at different amplitudes, and these amplitudes or shapes can repeat themselves. This may seem to imply some correspondence between wave revival and classical periodicity, and in some cases it does, but altogether revival is a phenomenon unique to waves with very faint connections to classical concepts.
