Abstract

The introductory section of Marian von Smoluchowski's seminal publication on the kinetics of Brownian motion ( Ann. Physik 1906, 21, 756) includes a simple model that provides lucid access to the topic. The present contribution is intended to draw attention to this model. On its basis, an expression is derived that allows the calculation of the mean displacement Brownian particles undergo.
