The principle was introduced ""in order to obtain the necessary relation to the ordinary theory of radiation in the limit of slow vibrations we are therefore led directlyto certain conclusions about the probability of transition between two stationary states in this limit."".The ""Principle of Correspondence"" is the physical priciple that the behaviour of atomic and other systems should approximate to that predicted by classical physics in certain specific circumstances where quantum effects are expected to be unimportent. Bohr used the principle to explain his theory of the hydrogen atom, which among other things successfully predicted many features of the spectrum of light emitted by energetic hydrogen atoms.

(Leicester & Klickstein, p. 417)""It was not till 1858 that a satisfactory theory of molecular constitution was advanced, simultaneously and independently, by thwo young chemists, Friedrich August Kekulé and Archibald Scott Couper. The theory of molecular constitution put foreward....by Couper and Kekulé rested on two main postulates, the quadriivalency of carbon,....and the capacity of the carbon atom for mutual linking or combining together to form a carbon ""chain"". By this hypothesis of the mutual linking together of carbon atoms - which waslater confirmed by experiment - it was possible to explain the formation of organic compounds containing a large number of carbon atoms. On the foundation of their postulates two postulates, moreover, (they) showed how the molecular constitution or mutual linking together of the atoms of a compound could be represented diagrammatically and the relstions between different compounds made readily intelligible.

‎First edition of the work in which Bohr introduced his famous Liquid Drop Model of the atom in order to interprete the nuclear structure. (The paper was not continued as Kalckar died the following year).""It had, of course, been clear to Bohr that analogies with atomic spectra could not be of help in interpreting his (earlier) picture of nuclear structure. Peripheral electrons, thinly spread within the atomic volume, can be compared to a dilute gas of particles interacting in pairs only. By contrast Bohr's picture of intranuclear motions of tightly bound nucleons should show 'essential collective aspects', he said. Now, together with Kalckar, he suggested that for nuclei a much more proper comparison would be with a drop of liquid. That analogy should not be taken too literally, the dynamics of a true liquid drop is vastly different from thta of nucleai. Yet the comparison, treated cautiously, was tempting and in the event proved fruitful in many respects, particularly in regard to collective motions.""(Pais ""Niels Bohr's Times"", pp. 339-40).""In the liquid drop model, formulated by Niels Bohr, the nucleons are imagined to interact strongly with each other, like the molecules in a drop of liquid. A given nucleon collides frequently with other nucleons in the nuclear interior, its mean free path as it moves about being substantially less than the nuclear radius. This constant ""jiggling around"" reminds us of the thermal agitation of the molecules in a drop of liquid. The liquid drop model permits us to correlate many facts about nuclear masses and binding energies"" it is useful in explaining nuclear fission. It also provides a useful model for understanding a large class of nuclear reactions."" (FAQ).Rosenfeld No 56.‎

‎First edition of these papers, in which Cartan intruced the concept of ""Torsion"", the main inspiration for Einstein in his searce for a unified field theory. The ECT of gravity is a modification of the General relativity Theory""The Einstein-Cartan theory, also known as the Einstein-Cartan-Sciama-Kibble theory, is a classical theory of gravitation similar to general relativity but relaxing the assumption that the affine connection has vanishing antisymmetric part (torsion tensor), so that the torsion can be coupled to the intrinsic angular momentum (spin) of matter, much in the same way in which the curvature is coupled to the energy and momentum of matter. In fact, the spin of matter in curved spacetime requires that torsion is not constrained to be zero but is a variable in the principle of stationary action. Regarding the metric and torsion tensors as independent variables gives the correct generalization of the conservation law for the total (orbital plus intrinsic) angular momentum to the presence of the gravitational field. The theory was first proposed by Élie Cartan in 1922 and expounded in the following few years. Dennis Sciama and Tom Kibble independently revisited the theory in the 1960s, and an important review was published in 1976. Albert Einstein became affiliated with the theory in 1928 during his unsuccessful attempt to match torsion to the electromagnetic field tensor as part of a unified field theory. This line of thought led him to the related but different theory of teleparallelism."" (Wikipedia).‎

‎Regnault announced here that he has found experimental evidence for the approximate nature of Dulong & Petit's Law for both elements and compounds.""His first results on the specific heat of solids were presented to the Academy of Sciences on April 3, 1840. One finds there the first experimental demonstration of the approximate law of Dulong and Petit, which had been ypothesized, rather than established, by these physicists. For 24 pure elements, Regnault demonstrated that this law was only partially true mostly because there was no accepted table of atomic weights at that time."" (Laurie Dahlberg)‎

‎First appearance of this classic paper in whic Maupas determined that fertilization in protozoa is essential to the indefinite continuation of a cell strain. His discovery proved an importent stimulus to subsequent investigation not only upon protozoa but also in the area of parthenogenesis.""He found in Paramecium that after generations of division, the stock becomes infeebled. Ultimately the individuals die, unless they meet partners for conjugation. When two such enfeebled individuals meet, their bodies are approximated and they interchange nuclear elements. Next, division takes place. The stock has regained its vigour. No differentiation of sexes is evident in the conjugatory process, though such differentiation can be traced in other prorozoa.""(Singer ""The Story of Living Tings"", p. 531 ff.).Thomas Hall ""A Source Book in Animal Biology"", pp. 458-60.‎

‎First printing of this importent paper being babbage's report on the Scheutz differnce calculator, explaining its functions by way of his own notations.""Babbage's report on the differnce engine built by the Swedish printer Georg Scheuts (1785-1873) and his son Edvard (1821-81), based on Babbage's own designs.... In 1854 the Scheutzes took their engine no. 2 to England in the hopes of marketing it. There they were introduced to Babbage, who received them with great friendliness and showed a lively interest in their work. Babbage devoted two whole days to investigating Scheutz' engine for which he had much praise, especially for the way they had succeeded in building it with the funds at their disposals.... As part of his effort to promote the Scheutz Engine, Babbage gave a talk on it before the Academie des Sciences, illustrated with drawings by his son henry, in which Babbage's system of mechanical notation was used to describe the machines construction and functions. This talk was published (the paper offered) without illustrations in the Academie 'Comptes rendus'. ((Hook & Norman ""Origins of Cyberspace"", No. 73).‎

(Entire volume offerd). Faradays papers: pp. 149-189 (Sixth series) + pp. 301-331 a. 481-520 (Seventh series). Internally clean and fine, printed on good paper.‎

‎First appearance in German - prepared by Faraday himself for publication in Annalen - of 2 historical papers in chemistry and physiscs in which Faraday in the first detects a new recombination-effect in electrolysis and in the second we have the MILESTONE PAPER in which Faraday announces the discoveries of further laws of electrochemistry, stating the general relations of electricity to chemistry and introducing new terms with precise meanings. The first part of the paper introduces his new terminology, giving the words a limited and precise meaning. These words, devised with the assistance of William Whewell, are now familiar to all chemists, electrode, anode, cathode, ion, anion, and cation. He also introduces the ""Volta-electrometer"", and arrives at the ""Law of electro-chemical equivalents"". The paper offered is one of Farday's most famous papers.""Another section of the paper is devoted to a closer examination of the law of constant electrochemical action with respect to water and to the development of a gas electrometer to measure quantities of electricity. Faraday's ""Volta-electrometer"" provided the first practical means for the quantitative measurement of electricity."" (Source Book in Chemistry p. 280-81).The Sixth series: ""In the course of his experimental investigations of a general and importent law of electro-chemical action, which required the accurate measurement of thegases evolved during the decomposition of water and other substances, the author was lead to the detection of a curious effect, which had never been previously noticed, and of which the knowledge, had he before possessed it, would have prevented many of the errors and inconsistencies occurring in the conclusions he at first deduced from his earlier experiments. The phenomena observed was the gradual recombination of elements which had been previously separated from each other by voltaic action. This happened when, after water had been decomposed by voltaic electricity, the mixed gases resulting from such decomposition were left in contact with the platina wires or plates, which had acted as poles"" for under these circumstances they gradually diminished in vo.umes, water was reprioduced, and at lust the whole of the gases disappeared.""(Abstract) - Faraday explains the causes of this recombination.‎
