The wave function does evolve in time, and the partial differential equation which describes this (schroedinger's Eqn) mentions the potential energy field and h-cross. I haven't looked at this stuff for a while, but I think it would be found that S's Eqn for a photon outside potential wells tends to show that it moves along at velocity c, as you might expect. So would a suitable energetic electron (though S's Eqn isn't really integrated with relativity). Nevertheless, as Donald Chan says, the lonely electron could be observed at A and then a short while later a very long distance away, because the evolution of the wave function will give (rather small but non-zero) values idefinitely far away at once. I wouldn't lose any sleep over it though, myself. ~e Julian Davies, waterloo ----------------------------------------------------------------- gopher://quux.org/ conversion by John Goerzen of http://communication.ucsd.edu/A-News/ This Usenet Oldnews Archive article may be copied and distributed freely, provided: 1.
