What is Lorenz attractor?
[[File:Lorenz_attractor_yb.svg|thumb|Plot of a Lorenz attractor]] The '''Lorenz attractor''' (also called '''Lorenz system''') is a [[system of equations.]] [[Edward N. Lorenz]] formulated the [[equation|equations]] as a simplified [[mathematical model]] for [[atmospheric convection]]. The equations are [[ordinary differential equation]]s, called '''Lorenz equations'''. They are notable for having [[Chaos theory|chaotic]] solutions for certain parameter values and starting conditions. In particular, the Lorenz attractor is a set of chaotic solutions of the Lorenz system which, when plotted, resemble a butterfly or figure eight. The notion of [[butterfly effect]] is coupled with that of the Lorenz attractor. Lorenz first used the phrase in a speech he gave in 1972. {{math-stub}} [[Category:Mathematics]]
