(In terms of the ideal gas law, k = n R / P.).""In 1802 he (Gay-Lussac) showed that different gases all expanded by equal amounts with rise in temperature. Charles had made the same discovery some years earlier but had not published it"" the credit therefore belongs to Gay-Lussac at least as much, and probably more.

‎First German edition of this milestone in mathematical statistics, first published in Latin as ""Theoria motus corporum coelestium in sectinibus conicis solem ambientum. 1809."" - In this work Gauss revealed for the first time his method of least squares. On January 1, 1801, the Italian astronomer Giuseppe Piazzi discovered the planetoid Ceres, but could only observe it for few days before it was lost in the glare of the Sun until the end of the year. After so many months of not being observed it was not possible to calculate with existing methods at which position it should reappear. However Gauss, at an age of 24, astounded when he in December predicted the exact location at which Ceres again could be observed. Gauss did not reveal how he had calculated the orbit of Ceres. First in 1809 Gauss published his second book ""Theoria motus corporum coelestium in sectionibus conicis solem ambientium"" (the offered item) in which he revealed his new method of orbit calculation. In the first part he dealt with differential equations, conic sections and elliptic orbits, while in the second part, the main part of the work, he showed how to estimate and then to refine the estimation of a planet's orbit using a new method involving minimizing the sum of squared residuals, e.g., the method of least squares. He was able to prove the correctness of the method under the assumption of normally distributed errors. It is here that the Gaussian curve, expressing statistical distribution in probablility, makes its appearance. This work, along with the 'Discuisitiones', was the fruit of the triumphal decade in Gauss' life and established his reputation as a mathematical and scientific genius of the first order.

Stimulated by this work he studied the reactions of other gases to see whether there were other simple relationshipas, and in 1808 he announced the la of combining volumes, which is now known as GAY-LUSSAC'S LAW, This generalization, obviously connected with some fundamental property of matter, was in part responsible for Avogadro's hypothesis.""(Leicester & Klickstein).Parkinson ""Breakthroughs"", 1809 C. - Leicester & Klickstein ""A Source Book in Chemistry"" pp. 292 ff.‎

‎First printing of probably Gauss' most importent work in physics by presenting his ""Principle of Least Action"" , which states that the motion of a system of points which are influenced both by each other and by outside conditions is such as to maximize the agreement with free motion, given the existent constraint. The work is based on his Potential Theory.""In it (the present paper) Gauss stated that the law of least constraint: the motion of a system departs a little as possible from free motion, where departure, or constraint, is measured by the sum of products of masses times the squares of their deviations from the path of free motion. He presented it merely as a new formulation equivalent to the well-known principle of d'Alembert. This work seems obviously related to the old meditations on least aquares, but Gauss wrote to Olbers on 31 January 1829 thai it was inspired by studies of capillarity and other physical problems."" (Kenneth O. May in DSB).The two papers (first printings) by Abel (book-lenghts memoirs) are his last works - he died 1829 and they were published after his death - on the theory of ""elliptic functions"", the discovery of which he shared with Jacobi. In these papers he mentions also the great discoveries published in his memoir 1826 (Memoire sur une proprieté générale d'un classe très-etendu de fonctions transcendentes), which was not published until 1841.Together with these 3 memoirs is found a paper by Alexander von Humboldt: ""Über die bei verschiedenen Völkern üblichen Systeme von Zahlzeichen und über den Ursprung des Stellenwerthes in den indischen Zahlen"", 1829.

‎First printing of an importent paper in which Gerhardt introduced the concept of ""type"" in organic chemistry in order to understand all substitution reactions.""Gerhardt adopted Laurent's nucleus, or unitary theory and combined it with the theory of types and radicals. In 1852 he discovered the anhydrides of organic acids and explained their structure by an extension of the water type of Williamson. He further proposed that all organic compounds could be related to one of four inorganic types: water, hydrogen, hydrogen chloride, and ammonia. These types could be used to explain most organic reactions as double decompositions. Since Gerhard felt that the formula of organic compounds never ecpressed the actual structure of the molecule, but only its reactions, he was satisfied with this theory and carried it no farther. However, it was a great advance in systematization and helped to bring order into the confused field of organic reactions.""(Leicester & Klickstein ""A Source Book in Chemistry 1400-1900"", p. 351.).""Gerhardt will occupy a permanent position in the history of Chemistry for his services to organic classification, for his concept of homology, for his preparation of acid anhydrides, and for his reform of equivalents.""(DSB V, p. 374).The volume contains further importent papers Marcelin Berthelot ""Sur la Bichlorhydrate D'Essence de Térébenthine"", pp. 223-230, by Arago, Edmond Becquerel etc.etc.‎

By 1900 he had developed an improved method of fractional crystallization, producing a greater concentration of radium salts in a shorter time, by using bromide instead of chloride. One direct result of his highly influential efforts, by which pure radium bromide became commercially available for research, was the 1903 verification by William Ramsay and Frederick Soddy of the production of helium from radium. Giesel was the first to observe the decomposition of water by radium salts.""(DSB).When his close friends and nearby colleagues Julius Elster and Hans Geitel obtained inconclusive results regarding magnetic influence upon Becquerel rays, Giesel provided a key to these rays’ non-X-ray character by his decisive proof of their magnetic deflectability in October 1899.‎

Every supposed stage in this process was abundantly illustrated from records of actual nebulae and clusters which he had observed.""(Berry).""Illustrated with many examples at every stage, these papers (1811 a. 1814) showed brilliantly how dynamic changes can be inferred from virtually static evidence"" and Herschel concluded by characterizing the Milky Way in its present stage of dissolution as ""this mysterious chronometer"".

‎First appearance of a fundamental paper in modern optics in which Helmholtz published his discovery of the resolution limit of the microscope. He found that the limit for the difference of magnitude that we are able to distinguish plainly is in general found equal to half the wave-lenght of theparticular light employed. A further increase in optical power beyond that of the best modern instruments does not therefore seem possible.‎

‎First appearance of an importent paper, founding the metric of interstellar space.It was the contemporous discoveries of the first minor planets, ceres in 1801, Pallas in 1802 and Juno in 1803, that prompted Herschel to investigate the origin of the spurious diameters of stars. ""Were their apparent diameters as real as those of planets or spurious as for stars? To address this question Herschel conducted an extensive series of experiments in his garden in Slough, examining through his telescope small globules of differing sizes and materials placed in a tree some 800 ft (ca. 244 m) away (Herschel 1805). His observations showed that for the smallest globules the diameters were all spurious and all of the same size. Furthermore, he found that, if just the inner part of the aperture of the telescope were used, the spurious diameters, whether of globules or of stars, were larger. If the whole aperture was employed, the diameters were smaller, and if only an outer annular aperture was used the diameters were smaller still. This experimental discovery that unfilled apertures can be used to obtain high angular resolution remains today the essential basis for interferometric imaging in astronomy (in particular Aperture Masking Interferometry). The theoretical justification of this result came with Airy's analysis of the diffraction pattern of a circular aperture 30 years later (Airy 1835), and it took a further 30 years before the idea of using multiple apertures was developed. In an early study the Reverend W. R. Dawes noted that he had frequently found great advantage from the use of a perforated whole aperture' and that when observing Venus this produced a central image of the planet perfectly colourless, and very sharply dened' (Dawes 1866). But it was left to Fizeau, in his submission to the Commission for the Prix Bordin the following year, to remark on une relation remarquable et n´ecessaire entre la dimension des franges et celle de la source lumineuse' and suggest that by using an interferometric combination of light from two separated slits il deviendra possible d'obtenir quelques donn´ees nouvelles sur les diametres angulaires de ces astres' (Fizeau 1868).""‎
