`Sure, but that's what advocates of Everett consider important. In Copenhagen you have to`

`apply the Born rule and then say those are the probabilities of my observation and *one*`

`of them occurs. Everett says they all occur and different instances of *you* observe`

`them. So which is your theory. You did not answer my question below.`

Brent,You are quibbling. It's just in other equations in the process. If it wasn't, itcouldn't be computed and we would have no theory of decoherence that produces resultsbut of course we do...Edgar On Saturday, December 28, 2013 7:28:24 PM UTC-5, Brent wrote: On 12/28/2013 4:21 PM, Edgar L.

It produces a set of probabilities.How do you get from there to the definite observation?And indcidentally, there's a step in decoherence which is NOT "in the equations".That is taking a partial trace over the environment in some particular basis (the"pointer" basis). This is not an evolution of the Schrodinger equation. BrentEDgar On Saturday, December 28, 2013 6:12:47 PM UTC-5, Brent wrote: On 12/28/2013 1:44 PM, Edgar L. Owen wrote:Jason, You'll have to ask the physicists who do think that. I can't speak for them. There is a good mathematical theory of decoherence that works fine in this world. It says nothing about MW whatsoever. Why do you think there is a connection?Decoherence only diagonalizes the system+measurement density matrix under a partial trace (over the environment). The diagonal them contains theprobability values for the different eigenstates of the measurement operator.So then how do you get from there to a definite result? Do you, like Omnes,simply observe that you have predicted probabilities and so one of them obtains. Or do you go with Evertt and say that all of them exist with different measures and the apparent randomness is an illusion due to our consciousness being relative to the different outcomes?
