Perhaps I should've been a little more precise in my language and instead of saying Schrodinger's equation is the ultimate reality I should've been saying the quantum wave function, which is approximated by Schrodinger and made precise by Dirac, is the ultimate reality. * *> And the observable problems that produces are ......? * *> I suppose that when the velocity of a particle is comparable to the SoL, the result of Schrodinger's equation will differ substantially from those of the Dirac equation, but offhand I can't offer a specific example. AG* *I can give you an example , for the lighter elements Schrodinger's equation can accurately predict their spectral lines. but for the heavier elements like uranium the electrons are going around so fast that they are relativistic, so you need Dirac's help. * *Earlier you asserted that QM is local. You were very certain. But don't Bell experiments strongly suggest instantaneous action at a distance, which suggests that QM is NON-LOCAL? AG * *When I started this thread, I gave an example of two experiments with an SG apparatus, one situated horizontally and another at a 30 degree angle from the horizontal. Since they produce different UP/DN states, that is at different angles for identical sets of incident electrons, I conjectured that this could only occur IF the electrons have no preexisting states, and the resultant states were caused by the measurement process. IOW, isn't this example sufficient to deny local realism? AG * -- You received this message because you are subscribed to the Google Groups "Everything List" group.
