...surely this challenges the concept of emergence? I'm imagining the subatomic equivalent of the butterfly in Beijing "causing" the thunderstorm in Toronto. Are *all* the changes which are so small as to "be" no change at all, still no change in aggregate? (If not, of course, they were never really *no* change.)
