Sorry, as Steven pointed out, events *that are modeled as* having zero
probability happen all the time. What you should not do with such
events is give them positive (ie, atomic) weight in statistical
calculations (= theory), and therefore you should not *predict* their
occurance as individuals (unless you have no fear of becoming a
laughingstock = practice).

I thought your name was Ewing. Is it really Brouwer?<wink/>
(Don't bother, I know. The reference to Brouwer is close enough for
tsukkomi[1].)
