In my book, I use OM in two distinctly different contexts. In chapter 4, the concept OM is introduced in the context of the strong self-sampling assumption. It is meant to be an experiential unit of sampling. In chapter 7, OMs are identified with the quantum state \psi, including identifiying the amplitude of \psi with the (necessarily complex) measure of the observer moment. \psi contains just that information needed to define where the observer is in space and time (coordinates are not enough to specify a location in the mulitverse). Are these two usages equivalent (or at least compatible). For the moment, I don't see why not, which is why I wrote the book that way. However, these things are not the states of Bruno's universal dovetailer (assuming that particular ontology). Multiple programs will generate the same sequence of experiences, the same sequence of \psi's. Can we answer the question of whether successive \psi's are related to each other? If \psi_1 and \psi_2 are related by a unitary transformation, the we can say that they're related, but the temporal relationship is undefined. Given an operator (observable), we can determine if \psi_2 lies in a lower dimensional eigenspace of the operator than \psi_1, hence \psi_2 is potentially a successor to \psi_1. Also if the magnitude of \psi_2 (if known) is less than \psi_1, it is also potentially a sucessor. But this is all a bit nebulous. I would perhaps like to put it this way - if \psi_1 and \psi_2 can be related by means of a projection operator corresponding to an observable that a conscious being may possibly make, then there is a consious observer in the Multiverse for whom those experiences are so related. Otherwise, they're not related. This probably entails that the set of observers is more likely the powerset of observer moments, depending on how much bite the anthropic principle has. Sorry for rabbitting on here... this is getting a bit speculative. -- ---------------------------------------------------------------------------- Prof Russell Standish Phone 0425 253119 (mobile) Principal, High Performance Coders Visiting Professor of Mathematics hpco...@hpcoders.com.au University of New South Wales http://www.hpcoders.com.au ---------------------------------------------------------------------------- -- You received this message because you are subscribed to the Google Groups "Everything List" group.
