# Lorenz attractor

KidzSearch Safe Wikipedia for Kids.

The **Lorenz attractor** (also called **Lorenz system**) is a system of equations. Edward N. Lorenz formulated the equations as a simplified mathematical model for atmospheric convection. The equations are ordinary differential equations, called **Lorenz equations**. They are notable for having 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.
