because I’ve assumed that no entanglement with the apparatus happens, but I guess for the action of the apparatus on the atom there probably has to be an equal and opposite reaction of the atom on the apparatus, of some form… and I’m not sure how to think of that in the context of quantum mechanics.
Yet this entanglement thing is the essence of QM, and a major contention issue still.
