Mathematical models for this phenomenon use the Fokker-Planck equation or the Langevin equation. Jean Perrin used it to obtain Avogadro's number, and Richard Feynman described a "ratchet" that uses it. This phenomenon is the physical version of the Weiner process, and is also [*] a stochastic process. The kinetic theory of gases was used in Einstein's 1905 explanation of it, and its namesake, a Scottish botanist, observed it in pollen grains in water. For 10 points, name this seemingly random motion of particles suspended in a fluid.
