Abstract
In 1930 L.S. Ornstein and G.F. Uhlenbeck [1] addressed again the problem of elaborating a suitable model for the Brownian motion, and they refined in more detail the Langevin dynamical equation to investigate the phenomenon at time scales shorter than those considered by Einstein [2] and Smoluchowski [3] in 1905-6.

Notes
- 1.
The behavior of a Brownian motion under the effect of an elastic restoring force has also been empirically investigated with a few clever experiments by E. Kappler [6] confirming the idea that the Smoluchowski approximation holds well when the drag \(\alpha \) is large.
