A Chaotic Pendulum in Phase Space with Javafigure of pendulum

What are Pendulum Applets?

Applets are Java's little application programs that are transferred over the Web to run on your local computer. Our applets solve the equation of motion of the pendulum numerically, display the results in various ways, and lets you interact with the program. There is a separate control window with buttons and slide bars to adjust the parameters and to control the animation.

Warning: the behavior of a chaotic system can be hypersensitive to the precise values of its parameters and initial conditions; even small changes can make big differences. For this reason we also list a number of parameter choices that give interesting behaviors; just double click on them to run the applet with these parameters. Then go experiment!
