WIENER, CHR. - THE CAUSE OF BROWNIAN MOVEMENTS DISCLOSED.

Erklärung des atomistischen Wesens des tropfbar-flüssigen Körperzustandes, und Bestätigung desselben durch die sogenannten Molecularbewegungen.

Leipzig, Johann Ambrosius Barth, 1863. Conemp. hcalf. 5 raised bands, gilt spine and gilt lettering to spine. A few scratches to spine. A small nich to middle of spine.Small stamp on verso of first -and general- titlepage. In: "Annalen der Physik und Chemie. Hrsg. von J.C. Poggendorff", Vierte Reihe Bd. 28, (=Poggendorff Bd. 118). Entire volume offered. X,644 pp. and 8 engraved plates. Wiener's paper: pp. 79-94.

First printing of this importent paper in the development of the atomic theory.
The cause of the Brownian movement was ascribed by C. Wiener in 1863 to bombardment of the suspended particles by the molecules of the liquid. This was confirmed by Svedberg in 1906; he found that the length of the path described agrees with that calculated from the kinetic theory by Einstein (1905) and Smoluchowski (1906).

The volume contains further notable papers: G. KIRCHHOFF "Zur Geschichte der Spectral-Analyse und der Analyse der Sonnenatmosphäre". Pp. 94-111.
L. LORENZ: "Ueber die Theorie des Lichts". Pp. 111-145. - Lorenz is well known for his theory of the electromagnetic nature of light, which he, independently of Maxwell, published in 1867.
