BOLTZMANN,Ludwig. “Über eine von Hrn. Bartoli entdeckte Beziehung der Wärmestrahlung zum zweiten Hauptsatze” AND WITH “Ableitung des Stefan’schen Gesetzes, betreffend die Abhängigkeit der Wärmestrahlung von der Temperatur aus der electromagnetischen Lichttheorie” [Derivation of Stefan’s law, concerning the dependency of heat radiation on temperature, from the electromagnetic theory of light], both in Annalen der Physik und Chemie, 1884, vol 22 pp. 31–39 and 291-294 in the volume of 616pp (with 9 folding plates).

Bound in contemporary calf with raised bands, and decorated boards, marbled edges. There is some small bit of rubbing two scrapes, but the volume still has a very nice appearance, and is quite tight and fresh. A near-fine copy, overall. $650

These two papers by Ludwig Boltzmann leading to the derivation of the Stefan-Boltzmann law. “A derivation of the law from theoretical considerations was presented by Ludwig Boltzmann (1844–1906) in 1884, drawing upon the work of Adolfo Bartoli…(who) in 1876 had derived the existence of radiation pressure from the principles of thermodynamics. Following Bartoli, Boltzmann considered an ideal heat engine using electromagnetic radiation instead of an ideal gas as working matter.”–Wikipedia

“Bartoli’s reasoning stimulated Boltzmann to work out a theoretical derivation, based on the second law of thermodynamics and Maxwell’s electromagnetic theory, of the fourth—power law previously found experimentally by Stefan…Although at the time the “Stefan-Boltzmann law” for radiation seemed to be an isolated result with no further consequences, it did at least show a possible connection between thermodynamics and electromagnetism that was exploited in the later quantum theory. In the 1920’s it was applied by Eddington and others in explaining the equilibrium of stellar atmospheres.”–Complete Dictionary of Scientific Biography online

(“The Stefan–Boltzmann law describes the power radiated from a black body in terms of its temperature. Specifically, the Stefan–Boltzmann law states that the total energy radiated per unit surface area of a black body across all wavelengths per unit time  (also known as the black-body radiant emittance) is directly proportional to the fourth power of the black body’s thermodynamic temperature T”–Wikipedia)
