WebBrownian Motion Brownian motion is the motion of a particle due to the buffeting by the molecules in a gas or liquid. The particle must be small enough that the effects of the discrete nature of matter are apparent, but large compared to the molecular scale (pollen in the early experiments, various plastic beads these days). http://galileo.phys.virginia.edu/classes/304/brownian.pdf
