"Edward N. Lorenz, the MIT meteorologist whose efforts to use computers to increase the precision of weather forecasts inadvertently led to the discovery of chaos theory and demonstrated that precise long-range forecasts are impossible, died of cancer Wednesday at his home in Cambridge, Mass. He was 90.
Lorenz was perhaps best known for the title of a 1972 paper, "Predictability: Does the Flap of a Butterfly's Wings in Brazil Set Off a Tornado in Texas?" The memorable title pithily summarized the essence of chaos theory -- that very small changes in a system can have very large and unexpected consequences."
