But in quantum mechanics that's not the reason we must settle for probability and can't achieve certainty; Bell's Inequality is violated so if quantum weirdness is caused by hidden variables (and I doubt they are) they can't be caused by local hidden variables like those of a coin flip. * * >> **It's true that you can't touch probability, but you can't touch >> entropy either, but both are "things" that exist in the physical world.* > > *> I don't think so.

At room temperature it's about 2.9 x 10^-21 joules per bit. That sure sounds physical to me. * *>> "Many Worlds, in it a measurement is simply a change.

JKC claims that consciousness has nothing to do with Many Worlds or with quantum mechanics, the only thing they have in common is that consciousness is strange and quantum mechanics is strange. * * John K Clark See what's on my new list at Extropolis <https://groups.google.com/g/extropolis>* e4a -- You received this message because you are subscribed to the Google Groups "Everything List" group.
