It implies something       non-sensical, yet there is all this evidence of something happening       that is very different from our normal macroscopic based intuition.              > Quantum mechanics tells us what results we'll get.

But I do think that this is something worth thinking       about in order to get a deeper understanding, perhaps beyond QM.       I've been studying QM since the early 1970's, and it is only in the last       decade or so that there has been much interest in the "interpretation"       of QM and what it implies about the mechanisms of particle       propagation. I think this is long over due.              > Sylvia.       >       > [*] Spell check says that this isn't a word, but what does it know?              BTW, I like "actee" as a word, even if it isn't in the dictionary!              Rich L.              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
