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 probability measure. For example in the Schrodinger Cat experiment, the cat is 50% alive or dead every time. I read the explanation on the basis of frequency but that did not make sense to me either. On Fri, Dec 27, 2013 at 4:23 PM, meekerdb <meeke...@verizon.net> wrote: > On 12/27/2013 9:18 AM, Edgar L.
