I think you mean "Lorenz attractors?" Sad actually, misunderstanding, that is. I believe Lorenz (as opposed to the physicist Lorentz) is/was a mathematician working on meteorology (atmospheric physics) in the early 1960s when he discovered what some call "the Mask." Simple descriptions appear in the books: %A R. Abraham %A C. Shaw %T Dynamics: The Geometry of Behavior %S Visual Mathematics Library %V 2, Chaotic Behavior %V 3, Global Behavior %I Aerial Press %C Santa Cruz, CA %D 1984 Starting on page 86? of part 2. There is also a SIGGRAPH video "Fly Lorenz." A detailed description can be found in %A C. Sparrow %T The Lorenz Equations %I Springer-Verlag %C New York %D 1982 There are also numerous books on non-linear dynamics, fractals, and that non-descriptive catch-all term "chaos." [See Gleick] Don't worry. When I first heard the term "Feigenbaum's" constant, "Oh! There's a new value for Feignebaum's constant!" I thought Edward Feigenbaum had done some real work, it took me a little while to realize my climbing partner meant "Mitchell Feigenbaum." Ach! Who's Mitchell?! Bill had never heard of "Edward Feigenbaum." Who's Edward?! I don't know. Ach! Science is getting too complex!
