CLAUSIUS and FIZEAU. CLAUSIUS, Rudolf. "On the Moving Force of Heat and the Laws Regarding the Nature of Heat itself which are deducible therefrom" in "The London, Edinburgh, and Dublin Philosophical Magazine and Journal of Science;" London, Richard Taylor, 1851, (fourth series) vol 2 pp 1-21 and 102-119. AND bound with Hippolyte Fizeau's "On the hypotheses relating to the luminous ether, and an experiment which appears to demonstrate that the motion of bodies alters the velocity with which light propagates itself in their interior" (same volume), pp 568-573. [++] The Clauisus is the first translation into English of his "Über die bewegende Kraft der Wärme und die Gesetze, welche sich daraus für die Wärmelehre selbst ableiten lassen" vol 79 pp. 368−397 and 500−524, 1850. In this paper, Clausius introduced the concept of entropy and stated the second law of thermodynamics in a form that is now widely recognized. He emphasized that heat does not spontaneously flow from a colder body to a hotter one, and he introduced the idea of entropy as a measure of the unavailability of energy for doing work. [++] "In 1851 [in the original appearance of the "Comptes Rendus." vol 33 pp 349-355, 1851, and which ap-pears here in translation I the same year] Fizeau found a way of overcoming the seemingly impossible difficulty of measuring the small increment in the velocity of light that in theory would be produced by a body in motion. His method was simply to produce interference fringes from rays of light that had passed through two parallel tubes containing a fluid moving in opposite directions. Even a relatively small difference in the velocity of the two light rays would cause a perceptible displacement of the interference fringes. Using air as the test medium, Fizeau discerned no change in the speed of light, a result that he expected because the refractive index of air is equal almost to one. With water, however, the velocity of light was altered by an amount that accorded reasonably well with Fresnel s formula. In 1886 A. A. Michelson and E. W. Morley repeated the experiment on a larger scale and confirmed Fizeau s results."--Complete DSB online.
