‎First printings of this series of epoch-making papers in which Janssen introduced the ""PHOTOGRAPHIC REVOLVER"" and its first successfull use leading to the ""First Film"" and hereby ""realized one of the operations necessary for cinematography""(DSB).In the first papers he conceived the idea of a device of historical interest, the photographic revolver, the technique of short exposures, which is announced here. The third paper is the epoch-making paper in which he specifically describes the ""revolver"" and its results, the ""first film"". The fourth paper is his responce to Marey's famous expriments with the ""revolver"" recording the flight of birds.""A long barreled canon-like automatic camera was invented in 1874 by an outstanding pioneer of modern astronomical photography, Jules Janssen. Janssen used the revolving plate technique and called his camera a 'pistol'. Janssen's method used the forerunner of a number of 'gun' cameras with a slowly revolving plate and shutter operated by clockwork. The photos were taken every 70 seconds along the margin of the negative and he used his pistol to record a 48 image sequence of the transit of Venus across the sun at an exposure rate of 1.5 seconds.""""In planning for the observation of the transit of Venus, which he was to observe in Japan on 9 Deembe 1874, Janssen decided to substitute for visual observation at the time of transit a series of photographs taken in rapid succession, which would permit him to measure the successive positions of the planet in relation to the solar limb. He ordered the construcion of an apparatus consisting of three circular disks with the same axis: the first, pierced by twelve slits, served as the shutter"the second contained a window" the photographic plate, which was circular, was fixed to the third. The first two disks turned with a synchronized movement, the shutter disk continuously and the other irregularly in the intervals of time in which the window was not swept by a slit. A series of separate images laid out on a circle was thus obtained on the plate. In a general manner the apparatus provided an analysis of a motion on the basis of the sequence of its elemental aspects. Here Janssen realized one of the operations necessary for cinematography, which was invented twenty years later, and which required, besides analysis, the synthesis of images."" (DSB).‎

It was then that he observed the helium line and forwarded the spectral data to ockyer. He also noted the size of the solar prominences. The day after the eclipse he attempted to take their spectra again and succeeded despite the absence of the obscuring moon. he then announced jubilantly that it was the day after the eclipse that was the real eclipse day for him. Lockyer also reported this method of studying prominences without an eclipse....Like Lockyer he lived to see his observation of the helium line vindicated by Ramsay's discovery of that element on earth.""(Asimov).""This (the discovery of helium lines in the sun by Lockyer) was announced on the same day by the French astronomer Janssen, who was in India observing a total eclipse. As a result, the French government some ten years later struck a medallion showing the heads of both scientists.By that time, the two men had made a much more dramatic discovery at the same time, this time in cooperation. Janssen, studying the spectrum ofthe sun during the eclipse, had noted a fine line he did not recognize. he send a report on this to Lockyer, an acknowledges expert on solar spectra. Lockyer compared the reported position of the line with lines of known elements, concluding that it must belong to a yeat unknown element, possibly not even existing on the earth.

A new form of condenser was tested on the small engine employed, and the results it yielded formed the starting-point of a series of investigations which were aided by a special grant from the Royal Society, and were described in an elaborate memoir presented to it on the 13th of December 1860 (the paper offered).

The papers are the French translations of his papers published in Abhandl. d. königl. Akad. d. Wissenscchaften in Berlin in 1861 and 1862.In the course of his preparatory work in the autumn of 1859, Kirchhoff made an unexpected observation. It had long been known that the dark D lines, noticed in the solar spectrum by Fraunhofer (1814), coincided with the yellow lines emitted by flames containing sodium.....Kirchhoff's unexpected discovery was that if the intensity of the solar spectrum increased above a certain limit, the dark D lines were made much darker by the interrposition of the sodium flame. He instantly felt that he had got hold of ""something fundamental"", even though he was at a loss to suggest an explanation. On the day following the surprising observation, Kirchhoff found the the correct interpretation, which wass soon confirmed by new experiments: a substance capable of emittiing a certain spectral line has a strong absorptive power for the same line....The dark D lines in the solar spectrum could accordingly be ascribed to absorption by a solar atmosphere containing sodium. Immense prospects thus opened up of ascertaining the chemical composition of the sun and other stars from the study of their optical spectra. A few more weeks sufficed for Kirchhoff to elaborate a quantitative theory of the relationship between emissive and absorptive poweer.""(DSB VII, pp. 381-82).PMM, 278 b. - Barchas, 1169-70 - Sparrow, 117 - Horbli, 59 - Dibner, 153 (the note).‎

It is at the same time the simplest and least understood law in physics. Kirchhoff's law states that given thermal equilibrium with an enclosure, the radiation inside will be always black, or normal, in a manner which is independent of the nature of the walls, or the objects they contain. This is known as the concept of universality. That is, that radiation within an enclosure can always be described by a universal function dependent only ontemperature and frequency. This universal function was first given us by Max Planck, in 1900. Kirchhoff's law STANDS AT THE HEARTH OF ALL MODERN ASTROPHYSICS. It is the basis for setting the temperature of the stars, for the gaseous model of the Sun, and for believing that we now know the temperature of the entire universe.""(Pierre-Marie Robitaille)..The research background for the paper was his unexpected observation that if the intensity of the solar spectrum increased above a certain limit, the dark D lines were made much darker by the interposition of the sodium flame. he instantly felt, that he had got hold of ""something fundamental"".

‎First appearance of the paper in which the authors set forth the equation which bears their name.The equation is named for Diederik Korteweg and Gustav de Vries who studied it, though the equation first appears in Boussinesqs work, 1877.""In mathematics and physics, a soliton is a self-reinforcing solitary wave (a wave packet or pulse) that maintains its shape while it travels at constant speed. Solitons are caused by a cancellation of nonlinear and dispersive effects in the medium.... Solitons arise as the solutions of a widespread class of weakly nonlinear dispersive partial differential equations describing physical systems. The soliton phenomenon was first described by John Scott Russell (1808-1882) who observed a solitary wave in the Union Canal in Scotland. He reproduced the phenomenon in a wave tank and named it the ""Wave of Translation"".Scott Russell's experimental work seemed at odds with Isaac Newton's and Daniel Bernoulli's theories of hydrodynamics. George Biddell Airy and George Gabriel Stokes had difficulty accepting Scott Russell's experimental observations because they could not be explained by the existing water wave theories. Their contemporaries spent some time attempting to extend the theory but it would take until the 1870s before Joseph Boussinesq and Lord Rayleigh published a theoretical treatment and solutions. In 1895 Diederik Korteweg and Gustav de Vries provided what is now known as the Korteweg-de Vries equation, including solitary wave and periodic cnoidal wave solutions."" (Wikipedia).‎

‎In this paper Korn gives a technical decription of his invention of his telephotographic machine (later the fax-machine)In 1902, Arthur Korn (1870-1945) in Germany invented telephotography, a means for transmitting still photographs by means of electrical wires. In 1907, Korn sent the first inter-city fax when he transmitted a photograph from Munich to Berlin. By 1906 his equipment was being put into regular service for transmission of newspaper photographs between Munich and berlin via telegraph circuits.

‎Fist printing of Kramer's doctoral thesis in which he calculated the relative intensities of the fine-structure components on the Basis of Bohr's Correspondence Principle and obtained results which generally agreed with Paschen's measurements.Bohr had concluded ""that polarizations and intensities should, in the limit of high quantum numbers, be given by the Fourier components of the quantized motion and that even at low quantum numbers the Fourier components in the initial and final states should give an indication of the intensities to be expected. In his doctoral thesis at Leiden in 1919 (published by the Royal Danish Academy of Sciences) - the paper offered - Kramers developed the mathematical formalism required to apply these ideas"" he also carried out detailed calculations for the case of a hydrogen atom in an external electric field. This led to a satisfactoery interpretation of the intensities of Stark components.""(H.B.G. Casimir in DSB VII, p. 491).‎

‎This edition of the first treatise on the differential calculus, first published 1696, is the first with the commentaries by the famous French astronomer Nicolas-Louis De Lacaille, taken from his noted ""Leçons élémentaires de mathématiques"".""The Analyse des infiniment petits was the first textbook of the differential calculus. The existence of several commentaries on it - one by Varignon (1725) - attests to its popularity. The question of its intellectual ownership has been much debated. Jean Bernoulli, who is known to have instructed L’Hospital in the calculus about 1691, complained after L’Hospital’s death that he (Bernoulli) had not been given enough credit for his contributions. L’Hospital himself, in the introduction to his books, freely acknowledges his indebtedness to Leibniz and to the Bernoulli brothers. On the other hand, he states that he regards the foundations provided by him as his own idea, although they also have been credited by some to Jean Bernoulli. However, these foundations can be found, less explicitly, also in Leibniz, although Leibniz made it clear that he did not accept L’Hospital’s Platonistic views on the reality of infinitely small and infinitely large quantities.""(DSB).‎

‎Scarce first edition of l'Hôspital's second book - his second successfull textbook - the manuscript of which was left completed at his death in 1704. His first book ""Analyse des infiniment petits pour l’intelligence des lignes courbes"", 1696 was the first textbook of the differential calculus, and his name lives on in the name of the rule for finding the limiting value of a fraction whose numerator and denominator tend to zero. His mathyematical teacher was Jean Bernoulli.The year in which Newton published the anti-Cartesian ""Arithmeticus"" there appeared in France a conspicuously successfull textbook on Cartesian geometry along the lines of that of Guisnée. This was the ""Traité Analytique des Sections Coniques"".... a book which contains less original material than that of Guisnée, but which is more extensive and closer to the modern manner of treatment. The work had been intended for publication at the time the authors famous calculus textbook appeared in 1696, but l'Hospital's illness apparently led to delay and it appeared posthumously in 1707. It is Cartesian in emphasis and although it consists of but one volume, follows generally the tripartite plan of Lahire and Ozanam: first an algebraic quasi-analytic treatment of the Conic Sections along the lines of Apollonian theory"" then an analytic study of the loci, and finally a long section on the customary construction by conics of the roots of cubic and quartic polynominal equations... LHospital sometimes used two axes and seems to have recognized the interchangeability of these, but he betrays some hesitation... In general, L'Hospital (like Descartes) was more interested in analytic geometry as a measure of ecpressing loci algebraivcally than as a method of deriving the properties of a curve from its equation.""
