Ah, but you could if you knew the position and condition of EVERY particle in the system, as well as continually updated information regarding outside influences like solar radiation, cosmic dust and the like. Weather station data points probably account for something like 10^-9999999 sand grain's worth of information from the entire system's Sahara. That coarse a sampling is only a little better than a random guess. We're way ahead of that on soundboards because we get to chose and modify some of the controlling factors. If we could control the surface temperature of the continents and oceans, we could have some better idea of next week's weather too because trends could be "corrected" and steered somewhat. >Your analogy brings the idea of quantum (spelling anyone) into the >arena--where sometimes looking at something changes its state.

Good point, and that's why we have to work with relatively coarse models. Our instrumentation isn't of fine enough resolution to tell us anything potentially useful without corrupting the measured item. It's hard to determine the location of an egg in space by bouncing bowling balls off it. Incidentally, the simulated piano sound installation in that Betsy Ross worked about like a long range weather forecast phoned in from a cave.
