Brownian Motion

http://www.dnatube.com/video/435/Brownian-Motion-randnom-movement

Brownian motion or pedesis (from Greek: πήδησις Pɛɖeːsɪs "leaping") is the presumably random moving of particles suspended in afluid (a liquid or a gas) resulting from their bombardment by the fast-moving atoms or molecules in the gas or liquid. The term "Brownian motion" can also refer to the mathematical model used to describe such random movements, which is often called a particle theory.
