Text__xQ55UKOcEd-WfYQ0GneCwQ_text=Einstein explains Boltzmann's relation between entropy and probability, S\=k lg W,  using the example of a particle suspended in a fluid which moves with a certain  probability by the distance z from the bottom of a cylindrical container because of  atomic thermal motion. He then deduces the law of Brownian Motion from an  observation of the amount of the substance diffusing through the cross-sectional  unit over a certain time [t]. He subsequently introduces the statistical law of motion of  a Brownian particle.
