My Programs

Java Applets:

I have written a couple of educational Java applets over the past year which have been relatively popular. You can find them at these links:

• Vector addition applet (and the source code)
• Kinetic theory applet (and the source code)

In both cases I started out by developing them as Macintosh-native applications, and later translated them into Java. The Macintosh programs can be found at these links:

• Vector Calculator
• Kinetic Theory (which I called "Molecular Dynamics," somewhat misleadingly)

TPlot

TPlot is a plotting application. You feed it your sets of data and it generates (two-dimensional) graphs for you. Multiple plots are supported, including multiple parametric plots, up to a maximum of four plots per graph. You can zoom in with the mouse, rescale just by resizing the window, and, niftiest of all, you can combine different plots just by using cut/copy and paste! Take a look at the TPlot homepage to learn more, or download it now. Bonus: if you have a developer environment for the Mac and occasionally write your own programs to do complicated calculations, the TPlot source code is available. You can compile it with your own code to generate plots and manipulate them in a fully interactive way!

I have just (April 1997) completed version 2.0 of TPlot, which supports scatter plots, more flexible choices to plot data from a file with many columns, high-resolution graphics, including exportable graphics to vector-drawing programs, and line dashing.
