Investigations on the Theory of the Brownian Movement

Arturo de Giorgi will present "Investigations on the Theory of the Brownian Movement"  (Albert Einstein, 1905,  translated into English by A. D. Cowper., 1959)

Abstract: In this paper it will be shown that according to the molecular-kinetic theory of heat, bodies of microscopically-visible size suspended in a liquid will perform movements of such magnitude that they can be easily observed in a microscope, on account of the molecular motions of heat. It is possible that the movements to be discussed here are identical with the so-called ‘‘ Brownian molecular motion ” ; however, the information available to me regarding the latter is so lacking in precision, that I can form no judgment in the matter.
