Hi Liz >> Is there something wrong with quantum indeterminacy?

Apart from the fact the MWI removes it? And that that is the point of MWI? And that probability questions in MWI are notoriously thorny? This is why I resort to the Quantum Suicide experiment or better still to Quantum Russian Roulette. The experimenter is 1-p certain of his own survival, not unsure about it. Otherwise, he'ld never take part. And this certainty has nothing to do with the fact that in the other outcome he dies. It doesn't matter what happens in that branch. His certainty is consequent on the fact that all outcomes obtain and being a MWI believer he believes just that. The Stanford Encyclopedia puts it: "The quantum state of the Universe at one time specifies the quantum state at all times. If I am going to perform a quantum experiment with two possible outcomes such that standard quantum mechanics predicts probability 1/3 for outcome A and 2/3 for outcome B, then, according to the MWI, both the world with outcome A and the world with outcome B will exist. It is senseless to ask: "What is the probability that I will get A instead of B?" because I will correspond to both "Lev"s: the one who observes A and the other one who observes B." I agree with that analysis, and disagree with subsequent attempts to smuggle some notion of probability back in. I'll read them again shortly just to see if they are any more convincing but on the face of it MWI has an issue with 1-p indeterminacy. It shouldn't really be there. Regards.

Interesting. I think there's a slight bias (in non-magicians) towards the coin coming down one way or the other - either the same as it started or the opposite, I can't remember which (There could be an ig-nobel in finding out for sure...) -- You received this message because you are subscribed to the Google Groups "Everything List" group.
