written by Fu-Kwun Hwang
This simulation shows Brownian motion, the random movement of particles in a fluid or gas due to molecular bombardment.  The simulation records the path of a suspended particle and also shows how gas molecules collide with the particle and the container walls.  The user can adjust the number of particles and the relative masses.
