Hardcover. Condizione: Near Fine. __+__Two Major Works in One Volume (1819)__+__ Augustin Fresnel and François Arago, Mémoire Sur l Action que les rayons de lumière polarisés exercent les uns sur les autres , in Annales de Chimie et de Physique; Paris, by Crochard, 1819, vol 10 pp. 288 305 in the volume of 448. with two folding plates (one relatively large). Beautifully rebound in half-calf and marbled boards, with new endpaper; very usable, quite a lovely job. The only demerit here is an old cellophane tape repair on the title page. Fine copy. __+__ Fresnel's theory was confirmed by French physicist François Arago who later carried out this experiment. Fresnel discovered that light was a transverse wave instead of a longitudinal wave as had previously been thought, and he presented his results in 1817. --Azooptics. (They) describe experiments demonstrating that light vibrates transversely to its direction of forward movement. (in this paper translated as Memoir on the action that the rays of polarized light exert on one another . --Parkson, Breakthroughs, (1819). __+__ Bound with: Pierre Dulong and Alexis Petit, Recherches sur quelques points importants de la Théorie de la Chaleur , same volume, pp. 395 427. Introduction of the Dulong-Petit Law, .a fundamental step in statistical physics. The Dulong-Petit limiting law for the specific heats of solids, one of the first general results in thermodynamics, has provided Mendeleev with a powerful tool for devising the periodic table and gave an important support to Boltzmann s statistical mechanics. Even its failure at low temperature, accounted for by Einstein, paved the way to the the quantum mechanical theory of solids . -- The strange case of Dr. Petit and Mr. Dulong , Roberto Piazza, 2018. They were concerned with the specific heats of elements; but if these elements really existed as atoms, it seemed possible that there might be a connection between the weight of the atom and the amount of heat acquired to raise the temperature of a given weight of that element by a certain amount."--Complete Dictionary of Scientific Biography online. The Dulong Petit law, a thermodynamic law proposed in 1819. states the classical expression for the molar specific heat capacity of certain chemical elements. Experimentally the two scientists had found that the heat capacity per weight (the mass-specific heat capacity) for a number of elements was close to a constant value, after it had been multiplied by a number representing the presumed relative atomic weight of the element. These atomic weights had shortly before been suggested by John Dalton and modified by Jacob Berzelius. --Wikipedia) __+__ Also bound with: Simeon Dennis Poisson, Sur la Theorie des instrumens a vent , pp 129-142 (relating to his Sur le Mouvement des fluides ´elastiques dans les tuyaux cylindriques, et sur la th´eorie des instruments `a vent, M´em. Acad. Roy. Sci. Inst., vol. 2, p. 305, 1819). The propagation of a compressional wave in a three-dimensional fluid medium was first considered by S. D. Poisson in 1819 [23] but it remained, however, for Hermann von Helmholtz to give in 1860 a more thorough treatment of this whole problem. __+__ And with: (William Frederic Edwards), Sur l'Asphyxie , pp 5-29 (being a continuation of two earlier papers from 1817 and 1818). With: Welter and Gay-Lussac, Sur un Acide nouveau forme par ke siufre et l'oxigene , pp 312-320.…
