Turing Machine Applet

The following Java™ applet animates a Turing Machine that can add or multiply numbers. The animation shows the flow of events in the calculation (the writing and reading of symbols on an endless tape) and the decision rules used to process each step in the calculation.

An explanation of the Turing Machine can be seen in the applet by clicking the button entitled "How the Applet Works".

If the applet does not appear after several seconds, or if it continues to appear all gray, you may need to install Java on your computer, or you may be behind a corporate firewall that blocks incoming Java applets.
