A DEMONSTRATION OF BROWNIAN MOTION

This applet demonstrates Brownian motion. The big particle can be considered as a dust particle while the smaller particles can be considered as molecules of a gas. On the left is the view one would see through a microscope. To the right is the supposed explanation for the jittering of the dust particle.
