The STP ChemicalDemon program displays a histogram of the energy of a demon that exchanges energy and particles with a one-dimensional lattice of particles. The purpose of this simulation is to understand how the demon acts as an ideal thermometer and ideal measurement of the chemical potential....

The STP TemperatureMeasurementLJ program simulates the exchange energy between a demon and a system of particles interacting via the Lennard-Jones potential. The program shows the kinetic temperature of the system as a function of time, and the energy distribution of the demon. The purpose of...

The GR Kerr Exploding program simulates orbits of objects released in an explosion in the equatorial plane of a rotating black hole using the Kerr metric. It is distributed as a ready-to-run (compiled) Java archive. Double clicking the gr_kerr_exploding.jar file will run the program if Java is...

As an Othello player I have used since 1988 several tools and programs for improving my game play. The most often used tools have been: Thor, Cassio and WZebra. Those programs are very interesting tools for studying Othello but they have all the same drawback: you are locked to one OS platform....
