Lorenz Equations

Here T r, b 0 are parameters. Ed Lorenz (1963) derived this three-dimensional system from a drastically simplified model of convection rolls in the atmosphere. The same equations also arise in models of lasers and dynamos, and as we’ll see in Section 9.1, they exactly describe the motion of a certain waterwheel (you might like to build one yourself).
