Really? Are you saying that the Sh. eq. gives a measure distribution for "outcomes" of "observables" even when there are no obserrver-moments? What is that supposed to mean? If by "observables" you mean Hermitian operators, how does the Sh. eq. do the above? My view, as I have stated repeatedly, is that it should be possible to derive a measure distribution for computations implemented by a physical system and that given a wavefunction & the Sh. eq., it should be possible to show that the ratios of the measures of appropriate computations that could be conscious (if present, e.g if there is a brain in the system) to the total measure of such are the usual effective probabilities. > My own preference is to talk about a quantum > history, which under some > (perhaps rather flaky) assumptions, could be > identified with the concept of observer moment. What's a "quantum history"? Any relation to the "consistent histories interpretation"? ===== - - - - - - - Jacques Mallah ([EMAIL PROTECTED]) Physicist / Many Worlder / Devil's Advocate "I know what no one else knows" - 'Runaway Train', Soul Asylum My URL: http://hammer.prohosting.com/~mathmind/ __________________________________________________ Do You Yahoo!?
