Perhaps I should have said between Msg and Mdev (although the argument is still similar) that U(t) |moves up>= |moves up> over the period t. i.e. once the electron interacted with the SG device it took a while to reach the detector but the state of the system did not change in an important way. I know that perhaps I should have put some position representation in there but I don't think that's what your getting at? I'm assuming that there is no collapse of the wavefunction so my experiences are all experienced because states evolve unitarily. I understand that the unitary operator is not an observable operator but I can observe the consequences of its action on a system because I measure observables that give different eigenvalues each time I look (experience things - my experiencing is a form of measurement). Are you saying that during an OM there is no change i.e. it is a static picture? Are you thinking that unitary evolution goes on in between the static pictures? Surely the t in the exponential means that the system evolves over that t. As a ist person I can observe things changing over this t. Can you help me to see if I am making an error of thinking?
