Brent: But it's also divided up according to the probability measure, so I
don't think conservation laws are violated in Everett's formulation.
Richard: I do not understand how it is divided up according to the
For example in the Schrodinger Cat experiment, the cat is 50% alive or dead
I read the explanation on the basis of frequency but that did not make
sense to me either.
