Imperial 8vo (26,4:19 cm), 18 pages 324-341 [1]. Letterpress on machine paper, in original publisher’s brochure on orange stock with black title printing.

First separate printing, in the original wrappers of Planck's derivation of the Fokker-Planck equation.

Content: The paper contains Planck's derivation of the Fokker-Planck equation, a generalization of Einstein's equation of Brownian Motion. The Fokker–Planck equation arises in a wide variety of natural science, including solid-state physics, quantum optics, chemical physics, theoretical biology and circuit theory. It's equation was first utilized by Fokker and Planck to describe the Brownian motion of particles. “In statistical mechanics, the Fokker–Planck equation is a partial differential equation that describes the time evolution of the probability density function of the velocity of a particle under the influence of drag forces and random forces, as in Brownian motion” (Wikipedia).

Condition: Wrappers at upper margin of front cover with small publisher's (?) stamp, bottom and top of spine with minimal faults, otherwise fine, uncut copy.

Rarity: APO (1988ff.) and ABPC (1973ff.) record no copy at all at auction.
