Chaos theory Lorenz attractor Butterfly effect
Edward Norton Lorenz (
May 23, 1917– April 16, 2008[ [http://web.mit.edu/newsoffice/2008/obit-lorenz-0416.html Edward Lorenz, father of chaos theory and butterfly effect, dies at 90 - MIT News Office ] ] ) was an American mathematicianand meteorologist, and a pioneer of chaos theory. He discovered the strange attractor notion and coined the term " butterfly effect".
Lorenz was born in
West Hartford, Connecticut. MITTech Talk, 1991-06-26, [http://web.mit.edu/newsoffice/tt/1991/24996/24998.html Lorenz Receives 1991 Kyoto Prize] ] He studied mathematics at both Dartmouth Collegein New Hampshireand Harvard Universityin Cambridge, Massachusetts. During World War II, he served as a weather forecaster for the United States Army Air Corps. After his return from the war, he decided to study meteorology. Lorenz earned two degrees in the area from the Massachusetts Institute of Technologywhere he later was a professor for many years.
Lorenz built a
mathematical modelof the way air moves around in the atmosphere. As Lorenz studied weatherpatterns he began to realize that they did not always change as predicted. Minute variations in the initial values of variables in his twelve variable computer weathermodel (c. 1960) would result in grossly divergent weatherpatterns. This sensitive dependence on initial conditions came to be known as the butterfly effect. [Term first recorded from Lorenz's Address at the Annual Meeting of the American Association for the Advancement of Science, in Washington, December 29, 1979.]
Lorenz went on to explore the underlying
mathematicsand published his conclusions in a seminal work titled "Deterministic Nonperiodic Flow", in which he described a relatively simple system of equations that resulted in a very complicated dynamical object now known as the Lorenz attractor.
He was awarded the
Kyoto Prizein 1991 and cited for "profoundly [influencing] a wide range of basic sciences and brought about one of the most dramatic changes in mankind’s view of nature since Sir Isaac Newton."

Lorenz continued to be active in his work well into his seventies, winning the
Kyoto Prizefor basic sciences, in the field of earth and planetary sciences, in 1991.

He was an avid outdoorsman, who enjoyed hiking, climbing, and cross-country skiing. He kept up with these pursuits until very late in his life, and managed to continue most of his regular activities until only a few weeks before his death. According to his daughter, Cheryl Lorenz, Lorenz had "finished a paper a week ago with a colleague." [ [http://www.nytimes.com/2008/04/17/us/17lorenz.html?ref=us Edward N.
