        That's one of the first topics I discussed on this list. My
answer now is the same as it was then. First, we know that some
observations do have more measure than others, because if not we'd see
only 'white rabbits'. Second, in physics we deal with ratios of infinite
quantities all the time. The key is to use a limiting process in the
definition. One can renormalize the measure distribution to make it into
an effective probability distribution. If you like you can take the
latter to be the fundamental quantity, but it's easier to work with
measure so we don't have to worry about the normalization.
