*This sounds reasonable, but when I try to apply I run into big trouble. Suppose there's a free Nitrogen molecule coming my way, and when it strikes me I experience a breeze. Am I ever entangled with it prior to impact? IIUC, its wf spreads with time. Same for an assumed wave packet. Not sure which wf is appropriate to apply, That aside, but whichever, that's an initial form which spreads and it is most concentrated when initially observed. But where is the observer to set the initial condition? TIA, AG* -- You received this message because you are subscribed to the Google Groups "Everything List" group.
