Brownian Motion: Order from Chaos
Brownian Motion
Brownian motion can be defined as the random motion of particles in a liquid or gas caused by the bombardment from molecules in the containing medium. Have you ever looked at dust particles in the sunlight shining through a window? They appear to move about randomly, even defying gravity. This is an example of Brownian motion in which the dust particles are bombarded on all sides by gas molecules in the air. Other examples of Brownian motion include the motion of grains of pollen on the surface of still water, the dif
