Will Kinney - http://www.acsu.buffalo.edu/~whkinney/ <http://www.acsu.buffalo.edu/~whkinney/index.html> - is on the right path ! with probabilities (and Sabine H. has always presented a view of probabilities that is something where I don't understand what she is talking about), but what this is all about is Sabine always states and states here): *QM (or the Schrodinger Equation, SE) is **incomplete** because it does not solve* the measurement problem*, so there must be a new nonlinear SE, and maybe hidden variables. And BTW, MWI doesn't solve *the measurement problem* either.* and Will is saying *If probabilities are integrated in QM, [*but somehow there are no hidden variables (whatever they are that Sabine is talking about)] *then it's OK.* @philipthrift -- You received this message because you are subscribed to the Google Groups "Everything List" group.
