Is symmetry the key?

2005-04-19 Thread David Barrett-Lennard
It seems that it is meaningless to talk about an absolute measure on the ensembles for the multiverse. However, we can make real progress by simply appealing to principles of symmetry. For example, when an atom emits a photon it seems reasonable to assume there is 50/50 chance of measuring "up"

Copenhagen Interpretation

This group tends to relate concepts back to MWI. Perhaps CI is a useful way to think as well... At a given point in time, a thinking entity is only aware of a small subset of its surroundings. This suggests an ensemble of all mathematical possibilities that are consistent with that mind in that

Using QTI to generate algorithms

Consider the following experiment... On a computer we generate a million numbers at random, and we write a program that tests whether the numbers are stored in ascending order, and if not causes the experimenter to be killed. A device that measures the polarisation of photons from a light source

I bought his book "Schrodinger's Rabbits" yesterday, and have been skipping around through it. Some of you may recall that I have questioned if there is any theoretical way we could estimate the size of the multiverse if it is not a continuum. I had suggested the size may be related to the n
