Lorenz, who died earlier this month, was a mathemetician and a meteorologist who, in the early 1960s, discovered that weather simulation models he was developing were exhibiting chaotic, non-predictive behavior, despite a fixed set of variables and no apparent equipment malfunction. Two identical weather simulation machines, side-by-side, given the same variables to process. Wildly different results. How?
