Thanks for visiting my site - I'll try to make it worth your while. Below are some small programs that I've written, mostly to demonstrate sundry applications of mathematics and physics. I've tried to provide variety but, as you'll see, I'm primarily a software guy and I'm not an authority on any of these topics. Usually I gain most of my knowledge about a subject while researching it for my demonstration. Full source code is included.

For something light, download the Earth Orbit demo, try the birthday trick or play Reversi. For hardcore geeks, the best I can offer is BigInt, RSA with BigInts, or the Newtonian Gravity demo. The Mandelbrot set viewer is light if you just admire the fractals, a bit heavier if you admire the underlying complex numbers.

My pièce de résistance is SpinShuffle, a unique new puzzle that is now available in free trial download form. If you like puzzles, I highly recommend checking it out at www.spinshuffle.com.
