Эдвард Нортон Лоренц ( 23 мая 1917 года — 16 апреля 2008 года) — американский математик и метеоролог, один из ранних исследователей в области теории хаоса. От открыл странный аттрактор и пустил в обиход выражение «эффект бабочки».

Начало карьеры

Lorenz was born in West Hartford, Connecticut. He studied mathematics at both Dartmouth College in New Hampshire and Harvard University in 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 Technology where he later was a professor for many years.

Исследования

Lorenz built a mathematical model of the way air moves around in the atmosphere. As Lorenz studied weather patterns he began to realize that the weather did not always change as predicted. Minute variations in the initial values of variables in his twelve variable computer weather model (c. 1960) would result in grossly divergent weather patterns. This sensitive dependence on initial conditions came to be known as the butterfly effect.

Lorenz went on to explore the underlying mathematics and 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 pattern of infinite complexity now known as the Lorenz attractor. At present, Lorenz still comes to his office on the 16th floor of the Green Building most days of week.
