Ernst von Meyer in History of Chemistry. For this discovery Lord Rayleigh and W. Ramsay received the Nobel Prize 1904. The volume also contains WILLIAM CROOKES "On the Spectra of Argon" OSBORNE REYNOLD "On the Dynamical Theory of Incompressible Viscous Fluids and the determination of the Criterion" KARL PEARSON "Contributions to the Mathematical Theory of Evolution. - II. Skew Variations in Homogenous Materials" etc.After having made several measuring of the densities of gases "Rayleigh came across a curious puzzle. With oxygen he always obtained the same density regardless of how the oxygen might be produced whether from one particular compound from a second compound or from the air. The situation was different with nitrogen. The nitrogen he obtained from air constantly showed a slightly higher density than the nitrogen he obtained from any of various compounds. Rayleigh could think of several ways in which the nitrogen obtained from air might be contaminated but none of the possibilities checked out experimentally. He was so frustrated that he went so far as to write to the journal "Nature" asking for suggestions. Ramsay a brilliant Scottish chemist asked permission to tackle the problem and received it. The upshot was that a new gas somewhat denser that nitrogen was discovered to exist in the atmosphere. It was named argon and it was the first of a series of rare gases of unusual properties whose existence had never been suspected."Asimow.Dibner Heralds of Science No. 50 - Neville Historical Chemical Library vol.

Raoult published his results on the effects of nondissociating organic solutes from which he deduced a general law controlling the lowering of freezing points the first paper offered. Four years later he extended this work to show the effect of solutes on vapor pressure the second paper offered. Having established the effect of nondissociating compounds he was in position to show that salts produced an eeffect which though anomalous could nevertheless be explained by the supposition that a dissolved molecule broke up into other molecules. This work was of great value in supplying a new method for determining molecular weights since the depression of freezing point and vapor pressure as well a the related rise in boiling point later discovered are proportional to the moleculat concentrations ofthe solutions; it was of equal value in supporting the ideas of van't Hoff on osmotic pressure. With the announcement of the dissociation theory of Arrhenius the anomalies were explained and the full significance of the generalizations of Raoult was recognized.

An equivalent statement is the law of constant composition which states that all samples of a given chemical compound have the same elemental composition. For example oxygen makes up 8/9 of the mass of any sample of pure water while hydrogen makes up the remaining 1/9 of the mass. Along with the law of multiple proportions the law of definite proportions forms the basis of stoichiometry."Wikipedia. </em> unknown

Poincaré actually developed the concept of these functions as part of his doctoral thesis. Under Poincaré's definition an automorphic function is one which is analytic in its domain and is invariant under a discrete infinite group of linear fractional transformations. Automorphic functions then generalize both trigonometric and elliptic functions." Wikipedia. </em> unknown

"Before he was thirty years of age Poincaré became world famous with his epoch-making discovery of the "automorphic functions" of one complex variable or as he called them the "fuchsian" and "kleinean" functions." DSB.These manuscripts written between 28 June and 20 December 1880 show in detail how Poincaré exploited a series of insights to arrive at his first major contribution to mathematics: the discovery of the automorphic functions. In particular the manuscripts corroborate Poincaré's introspective account of this discovery 1908 in which the real key to his discovery is given to be the recognition that the transformations he had used to define Fuchsian functions are identical with those of non-Euclidean geometry. See Walter Poincaré Jules Henri French mathematician and scientist.The idea was to come in an indirect way from the work of his doctoral thesis on differential equations. His results applied only to restricted classes of functions and Poincaré wanted to generalize these results but as a route towards this he looked for a class functions where solutions did not exist. This led him to functions he named Fuchsian functions after Lazarus Fuchs but were later named automorphic functions. First editions and first publications of these epochmaking papers representing the discovery of "automorphic functions" or as Poincaré himself called them the "Fuchsian" and "Kleinian" functions."By 1884 Poincaré published five major papers on automorphic functions in the first five volumes of the new Acta Mathematica. When the first of these was published in the first volume of the new Acta Mathematica Kronecker warned the editor Mittag-Leffler that this immature and obscure article would kill the journal. Guided by the theory of elliptic functions Poincarë invented a new class of automorphic functions. This class was obtained by considering the inverse function of the ratio of two linear independent solutions of an equation. Thus this entire class of linear diffrential equations is solved by the use of these new transcendental functions of Poincaré." Morris Kline.Poincaré explains how he discovered the Automorphic Functions: "For fifteen days I strove to prove that there could not be any functions like those I have since called Fuchsian functions I was then very ignorant; every day I seated myself at my work table stayed an hour or two tried a great number of combinations and reached no results. One evening contrary to my custom I drank black coffee and could not sleep. Ideas rose in crowds; I felt them collide until pairs interlocked so to speak making a stable combination. By the next morning I had established the existence of a Class of Fuchsian functions those which come from hypergeometric series; i had only to write out the results which took but a few hours.the transformations that I had used to define the Fuchsian functions were identical with those of Non-Euclidean geometry." </em> hardcover

Peltier's use of small samples of these nonductile materials was fortunate because the anomalous behavior of these materials led him to construct a thermoelectric thermoscope and to measure the temperature distribution along a series of thermocouple circuits. He discovered that a cooling effect can take place at one junction and an excessive heating at the other. He then confirmed this discovery by using an air thermometer in place of the thermoscope. Peltier did not pursue the effect he had discovered and its importence was not fully recognized until after the thermodynamic work of William Thomson twenty years later."DSB X p. 500.Wheeler Gift no 2684. - Ronald's Library p. 389. - Parkinson "Breakthroughs" 1834 P. </em> unknown
