Yeah, I haven't quite understood, or been told, what happens to, for example an electron and its wavefunction, when you stop to measure it.
I mean, an electron has a wave function describing its position and so on in the region of space it is confined. When I measure it, I get an output, and the wavefunction collapses - as far as I understand. But then, when I stop measuring, the electron has not been "destroyed" has it? So does it resume its original wavefunction, and continue as nothing has happened, or have I totally misunderstood something? :)
