Brownian motion is a special case of an Ito process, and is the main building block for the diffusion component. In fact, any diffusion is just a time scaled Brownian motion. One important property of Brownian motion is that its increments are uncorrelated (in fact, they are independent) whereas in general Ito process there can be loads of cross-correlation happening.

Essentials of Brownian Motion and Diffusion (Mathematical Surveys & Monographs) (9780821815182): Frank B. Knight: Books. The Brownian motion of particles suspended in liquids can be described from an equation sphere and the translational diffusion coefficient describing the net.

Brownian motion is named in honor of his work. As a botanist, Brown first observed the effect in pollen floating in water, where it is visible with the naked eye. Through experimentation, Brown determined that the specks of pollen were not propelling themselves independently, but …

A long time ago I started writing a book about Markov chains, Brownian motion, and diffusion. I soon had two hundred pages of manuscript and my publisher 

Brownian motion in a smoke cell; Brownian motion of carbon particles in water; Diffusion of copper sulfate crystals in water; Diffusion of copper sulfate solution in water; Diffusion of nitrogen dioxide into air; Diffusion of hydrogen into air; Diffusion of ammonia and hydrogen chloride gas; Diffusion of bromine vapour Brownian motion will then be abstracted into the random walk, the prototypical random process, which will be used to derive the diffusion equation in one spatial dimension. This will provide the basis for our discussion of atomic diffusion mechanisms in solids, which is the subject of the next chapter. Here is where I get confused. I have also been told that due to Brownian motion, the net displacement of any given particle is zero.
