Download-able Programs (for your amusement):
1) Turing Machine Simulator:
Simulates actions of TM's.
Outputs tape results + statistics.
Comes with transition functions for various TM's including
the Universal TM
and includes programs to encode and decode TM's into
binary form for UTM.
Includes source code as well as executables for x86.

2) Program that determines if 2 arbitrary regular expressions
are equivalent (C source code and .exe for x86):

3) Windows 95 program that displays a bubble which
you can "whack" any number of times and observe the
waves traverse the surface and criss-cross each other.
Does not use any differential equations, but rather
the solutions to the angular component of Laplace's
equation, called "spherical harmonics".
Several parameters including rotations in 3-d
can be changed by the user:

4) Interested in Genetic Algorithms?
Program that generates 3-legged creatures that have
"evolved" in a 2-d Darwinian world. The victors know
how to crawl towards "food". Included is a Windows 95
"viewer" that allows you to see the critters roam around.
The viewer also has other goodies such as a fractal
generator that allows the user to zoom in or out of the patterns.
These fractals are based on the idea of cycloids inscribed
within other cycloids. Comes with a readme file.

5) Exotic electron orbitals:
This program displays the quantum mechanical
"trajectories" inside a hydrogen atom of an electron
in any number of levels of excitation and angular
momentum. Visualizes seldom seen orbitals for high
quantum numbers. (Windows 95)

Einstein quotes:
Only two things are infinite: the universe and human stupidity. And I'm not sure about the universe.
Unthinking respect for authority is the greatest enemy of truth.
The important thing is not to stop questioning. Curiosity has its own reason for existing.
It should be possible to explain the laws of physics to a barmaid.
If we knew what it was we were doing, it would not be called research, would it?
