More classic Newtonian physics works on the "macro levels." Quantum mechanics works on the large scale, too. It's just that the "weird" effects diminish with size. So while we can't be absolutely sure where a basketball is if we know its momentum, the size of the possible error in its location is several magnitudes smaller than we can actually measure in practice. That is, we can figure out where it's located to within an atom or so. And for a macro object, that's all we really need to know. A lens cap, on the other hand, is sufficiently small so that even if you think you've removed it, by the laws of quantum mechanics, it might still be covering your lens. So it's not really your fault for those missed shots. It's Heisenberg's fault. :) Eric - -- To unsubscribe, see http://mejac.palo-alto.ca.us/leica-users/unsub.html
