Propagation, Spreading, and Scattering
The state of each submicroscopic particle in a system is described, as we have noted before, by a function Ψ. The observable probability-density distribution of the particle over space at each time t and the observable changes associated with increasing time are derivable from this function. Analogous to the classic mechanical current found in a moving fluid is an apparent current of streaming probability density.
