THE SMOLUCHOWSKI EQUATION

SMOLUCHOWSKI, MARIAN.

Über Brownsche Molekularbewegung unter Einwirkung äusserer Kräfte und deren Zusammenhang mit der verallgemeinerten Diffusionsgleichung.

Leipzig, Barth, 1915. 8vo. In the original printed wrappers. Author's presentation offprint with the printed presentation statement on top of frontwrapper "Überreicht vom Verfasser" [i.e. "Given by the author"]. Offprint from "Annalen der Physik", Vierte Folge, Band 48, 1915. A very fine copy, near mint. Pp. 1103-1112.

Scarce presentation offprint with the printed presentation of Smolukowski's important drift-diffusion equation or the Smoluchowski equation. Here he documented that In some cases, the average velocity field exists because of a force, for example, the equation might describe the flow of ions dissolved in a liquid, with an electric field pulling the ions in some direction. This is referred to as the drift-diffusion equation (not to be confused with the Einstein-Smoluchowski relation)
