## Module content and teaching

###### Principal aims

"Brownian motion was originally the description given in physics for the random erratic movement of molecules. In 1905 Einstein made a detailed study in which he postulated certain properties should hold. In 1923 mathematical Brownian motion was born when a famous mathematician, Norbert Wiener, showed how to construct a random function W(t) giving the molecules ""position"" at time $t$ which had Einstein's properties. We will investigate methods of constructing such random functions. It turns out the Gaussian distribution is essential - it is impossible to do with any other distribution. "
