Bruce - the ony way you can do branch counting to get measure is if the branches obey a physically symmetry. Then you can apply the indifference principle - just as you say the probability of a die outcome is 1/6th, you can say the probability of up or down is 1/2. But by construction, your "counter example" does not have symmetric branches, therefore branch counting does not apply. All we can say is that there will be some probability of each outcome. Just like slicing a cake, you can slice the Multiverse in many different ways, with different effects on the measure. Quentin is not claiming to be able to generate the Born rule from all of this, just that it is an open problem. Some say the Gleason theorem is sufficient for this. My own derivation sort of goes the other way. Starting with a probability measure attached to each branch, you can construct an inner product space (and prove it is a Hilbert space) that gives you the Born rule. Is this the only way of constructing an inner product space? The Gleason theorem suggests it is. What would be nice is to have all of that arise naturally from information processing considerations. I don't know if that is possible. It might be we need to augment our theory of computation with something like quantum computation, for example. -- ---------------------------------------------------------------------------- Dr Russell Standish Phone 0425 253119 (mobile) Principal, High Performance Coders [email protected] http://www.hpcoders.com.au ---------------------------------------------------------------------------- -- You received this message because you are subscribed to the Google Groups "Everything List" group.
