..., then it "collapses." I'm guessing that after collapse, it's not a wave (probability function) anymore, but a data point. However, there's no difference between a probability function and any other integrable real-valued function in math, except of course the integral from - to + infinity of the former is always 1. You know more about the multidimensional case than I do; I'm all 1-D.
