This phenomenon is the original inspiration for the Langevin equation, but that description breaks down at small timescales because inertial forces overcome thermal ones.

This phenomenon is the original inspiration for the Langevin equation, but that description breaks down at small timescales because inertial forces overcome thermal ones. This phenomenon is the subject of the second of the Annus Mirabilis papers in 1905, where he assumed that this problem satisfies the diffusion equation to show that the distance travelled is proportional to the square root of time elapsed. A Scottish Botanist discovered this phenomenon while looking at pollen grains in water but it was first explained comprehensively by Einstein. For 10 points, name this process, the random motion of tiny particles in a fluid.
