OOPS! I sent this reply only to Hal - instead of the list. So here's the fwd to the list. Brent Meeker On 04-Sep-02, Hal Finney wrote: > I think on this list we should be willing to seriously > consider the many-worlds interpretation (MWI) of quantum > mechanics as the ontology for our universe

Dear Tim, Thank you for the reply but ... Well, I did not mean to imply that we should "look to Egan's fictional character for actual theories" or any other novel or fiction... I think that I asked you a similar question before regarding the idea that Egan is discussing using the fictional ch

hi all. Ive started a group dedicated to finding a sequel theory to quantum mechanics focusing on local hidden variables. now 1 year old, almost 3000 msgs already, 100 subscribers. several graduate students, one practicing QM physicist working in superconductors etc., hope to see you there. will

I think on this list we should be willing to seriously consider the many-worlds interpretation (MWI) of quantum mechanics as the ontology for our universe. In particular, we should not assume that wave function collapse is anything more than an illusion caused by decoherence of formerly interacti

Dear Tim and scerir, I am VERY interested in this discussion! ;-) It seems to me that fact that the amplitudes of observables in QM are complex valued and thus do not obey trichotomy may be at the root of the difficulty. When we attempt to make sense of situations such as those we obtain in E
