For 10 points, first discovered by looking at pollen grains under a microscope, name this phenomenon, the random movement of particles suspended in a fluid?
On an m-dimensional Riemannian manifold, the characteristic operator of this process is one half the Laplace-Beltrami operator. Lévy's condition describes the conditions necessary for a continuous process to be one. On long timescales it is well described by the Langevin equation and the workings of this Weiner process in fluids was the subject of a 1905 paper by Albert Einstein.
