‎1950 Trois gouaches sur papier cartonné, (1950), 32.5 x 24.7 cm.‎

‎Ces trois maquettes de mobilier de bureau ont été réalisées par le fabricant français de meuble Mercier Frères. La première gouache représente un bureau plat, très fonctionnel avec ses nombreux tiroirs. Un téléphone, un encrier et un livre matérialisent cette réalisation. La seconde gouache représente une chaise de bureau, capitonnée de vert, et à l'assise confortable. Un bureau, de confection plus modeste, vient compléter cette gamme. Une machine a écrire, recouverte de sa housse, et un dossier complètent cette scène. Fondée en 1828, Faubourg Saint-Antoine, par Claude Mercier, l'atelier de meuble deviendra Mercier Frères en 1867 et fermera ses portes dans les années 1980. Mercier Frères participa à de nombreuses expositions internationales. En 1924 Mercier Frères a été choisi pour représenter la France à l'Exposition Française de New-York. Fines pliures aux coins, infimes trous d'épingle et taches.‎

This letter was shown by Arago to Fresnel, who at once saw that it presented the true explanation of the non-interference of beams polarised in perpendicular planes, and that the latter effect could even be made the basis of a proof of the correctness of Young's hypothesis" for if the vibration of each beam be supposed resolved into three components, one along the ray and the other two at right angles to it, it is obvious from the Arago-Fresnel experiment that the components in the direction of the ray must vanish" in other words THAT THE VIBRATIONS WHICH CONSTITUTE LIGHT ARE EXECUTED IN THE WAVE-FRONT.""

But light waves, because of their transverse vibrations, are more complex than sound waves. Light can assume different forms of planes of vibration as well as different intensities. Using the same spectroscopic apparatus as in the preceeding experiment, Fizeau and Foucault observed the interaction of two rays produced by passing a single polarized ray through a birefringent crystal. In this case, instead of obtaining alternating bands of light and dark, they obtained bands of light periodcally polarized in different planes of vibration.""(DSB V, p. 19).‎

‎First appearances of this groundbreaking series of papers and memoirs in which Fresnel established the scientific basis for the wave theory of light and gave the theoretical framework for explaining, in the context of his theory of the transversal nature of lightwaves, the phenomena of double refraction, refraction, dispersion, polarization, interference, diffraction patterns, diffraction fringes as light spreads around objects, etc. He developed mathematically the hypothesis of the wave nature of light and he demonstrates its conformity with experience. His study of light was a dynamic interplay between theory and observation, between mathematics and experiment. - The offered series also comprises the contributions from Arago and the rapports from The French Academy's committees by Ampère, Biot and Fourier - see below nos. 6,11,14,15,a.nd 18.""From the point of view of method, his investigations extended from the manual operations of the laboratory to the most abstract mathematical analyses. Few physicists since Newton had been so versatile.""(Silliman in ""Historical Studies in the Physical Sciences"", vol. 4, p. 155.).""The wave-thory at this time was still encumbered with difficulties. Diffraction was not satisfactorily explained" for polarization no explanation of any kind was forthcoming the Huygenian construction appeared to require two different luminiferous media within double refracting bodies and the universality of that construction had been impugned by Brewster's discovery of biaxial crystals. The upholders of the emission theory, emboldened by the success of Laplace's theory of double refraction, thought the time ripe for their final triunph and as a step to this, in March 1817 they proposed Diffration as the subject of the Academy's prize for 1818. Their expectation was disappointed" and the successful memoir afforded the first of a series of reverses of which, in the short space of seven years, the corpuscular theory was completely owerthrown. The author was Augustin Fresnel...""(Whittaker ""A History of the Theories of Aether & Electricity"", vol. 1, p.107 ff.).""This concept of transverse waves met with the greatest hostility from the scientists of the day, who could not imagine an extremely fluid and rarified ether which at the same time possessed the mechanical properties of a rigid body. Even Arago admitted that he could not follow the exuberant engineer in his ideas. ButFresnel was convinced that at last he had the key to many mysteries, and with his model of waves he gave a full clarification of the phenomena of polarization. With insuperable precision he explained a long series of extremely complicated experiments, such as those of chromatic polarization that Arago himself had discovered by chance in 1811, and which the followers of Newton could not explain in spite of all their efforts. Following this line Fresnel reached the synthesis which is his masterpiece....we must recall the final interpretation that he gave of the famous phenomenon of partial reflection by transparent surfaces, that simple phenomenon which until then had puzzled Grimaldi, Newton, and Huygens, and which in Malus's experiments had unexpectedly acquired a special importencee as it had been compared to the great mystery of double refraction.""(Ronchi ""The Nature of Light"", p. 255 ff.).Comprising:1.

‎First German edition of Fresnel's epoch-making memoir from the French Academy (1826) and incorporating his experimental results from the years 1815-19, in which he for the first time explained the causes of the diffraction effects as the mutual interference of the secondary waves emitted by those portions of the original wave-front which have not been obstructed by the diffraction screen. His methods of calculation utilized the principles of both Huygens and Young and he summed the effects due to different portions of the same primary wave-front. He demonstrates that the transverse wave theory of light explains the observed phenomena of reflection, refraction, interference, polarization, difraction patterns, diffraction fringes etc., making a strong case for the theory of the transverse nature of light waves. The memoir records also Fresnel's famous mirror-experiment.""In broad contect Fresnel's work can be viewed as the first successfull assault on the theory of imponderables and a major influence on the development of nineteenth-centurty energetics."" (DSB V, p. 171).""Augustin Fresnel seems to have adopted a wave theory of light from the very beginning of his studies. His first paper, presented to the Academy...in October 1815, and entitled ""La Diffraction de la Lumiere"" (the paper offered), was written after a long correspondance with Arago, who had promised Fresnel his full support. ""The wave theory"" Fresnel wrote, ""is well suited to explaining the complicated propagation of light phenomena, and since, as we know from the case of sound, waves can surcomvent obstacles, I decided to make a study of shadows.....It is because they cross in regions common to them both that two pencils of rays can produce fringes. hence it follows that the vibrations of rays which cross at very small angles can cancel out whenever crests of one correspond to the throughs of the other.""The voume contains further a notable paper by AMPÈRE ""Bestimmung der krummen Fläche der Lichtswellen in einem Mittel, dessen Elasticität verschieden ist nach den drei Hauptrichtungen, d.h. nach debjenigen, in welchem die von der Elasticität erregte Kraft in desselben Richtung wirkt, in der die Theilchen dieses Mittels verschoben wurden.""

‎First printing of Lebedew's importent paper which he presented at an international conference (1899), and in which he described his detection of the pressure of light.""He was interested in the possibility that light might exert pressures. This had been predicted by Maxwell's equations and it was a handy explanation, for instance, for the fact that comet's tails always pointed generally away from the sun whether the comet was approaching the sun or receding. In 1901 (in the paper offered), using very light mirrors in a vacuum, Lebedew was actually able to observe and measure the pressure exerted by light, again confirmning Maxwell's theories, as well as providing a vehicle for Arrhenius' life-spores.""(Asimov).Parkinson ""Breakthroughs"", 1899 C.‎

‎Extremely scarce first edition of the paper in which Lorenz, independent of Maxwell, stated that light is electromechanical in nature, probably inspired by his former teacher H. C. Oersted, the discoverer of electromagnetism and professor at the Polytechnic College, he aimed at unifying the forces of nature without introducing new physical hypotheses. ""The idea that the various forces in nature are merely different manifestations of the one and same force has proved itself more fertile than all physical theories"".Most impressive of all Lorenz’ achievements in optics is his electromagnetic theory of light, developed in a relatively unknown paper of 1867, two years after Maxwell’s famous paper on the same subject. At that time Lorenz did not know Maxwell’s theory, and his own approach was quite different. Lorenz’ electromagnetic theory of light can be described briefly as an interpretation of the light vector as the current density vector in a medium obeying Ohm’s law. This paper contains the fundamental equations for the vector potential and the scalar potential or - for the first time - the corresponding retarded potentials expressed in terms of the current density vector and the electrical charge density. The concept of retarded potentials had already been introduced in an earlier paper by Lorenz in connection with research on the theory of elasticity. He found that the differential equation for the current density vector was the same as his fundamental wave equation for the light vector, completed with a term which explains the absorption of light in conducting media, and that his theory led to the correct value for the velocity of light."" (Mogens Pihl in DSB).The paper was published in English, 1867 ""On the identity of the vibrations of light with electrical currents.""

‎First apperance of Majorana's paper which was the first experimentally to prove the speed of light as set forth by Einstein in his special relativity theory. Majorana was critical to Einstein's relativity, and he therefore tried to prove experimentally that the postulate of the speed of light was wrong. His experiments turned out otherwise, and he hereby proved Einstein's postulate that the speed of light was independent of the velocxity of its source.‎

‎First appearance of Malebranche's importent paper in which he elucidates and expounds his model of matter. He ""utilized this model to study luminous phenomena and to provide an account of universal gravitation, of planetary motion, and of gravity. This model, considered in itself as the seat of action in the universe, inspired his idea that light consists of vibration in a medium under pressure.""(DSB).""Malebranche’s subtle matter is a unique primary substance that, forced to move at high speed in a closed universe, is obliged to whirl in vortices the dimensions of which can decrease without limit, a property predicated on the supposition that no vacuum can exist. The formula for centrifugal force then requires that these small vortices, which are actually the universal material of all physical entities, be not only perfectly elastic but capable, as well, of releasing a ""fearful"" force upon breaking up. A theoretical model of this sort is not a trivial invention.The memoir alluded to above (the paper offered here) won him membership in the Académie des Sciences at the time of its reorganization in 1699. Henceforth, Malebranche actively participated in scientific life, while gathering the material he was to incorporate in the sixth edition of the Recherche (1712), in which he made the necessary revisions, corrections, and additions in those sections devoted to all the topics in which he thought science bore on his philosophy.""(DSB).‎

‎Versuche über das Sonnenlicht.‎

‎Halle, Rengerschen Buchhandlung, 1803. Without wrappers as extracted from ""Annalen der Physik. Herausgegeben von Ludwig Wilhelm Gilbert"", Jahrgang 1802, Bd. 12, Zwölftes Stück. Pp. 409-416. Titlepage to vol. 12.‎

‎This is Ritter's first expositon of his discovery of ultraviolet light. It was announced the year before in a halfpage letter addressed to Gilbert's Annalen and printed in the Annalen. With that discovery, it became clear that visible light represents no more than a fraction of a continous spectrum.A year earlier, in 1800, William Herschel discovered infrared light. This was the first time that a form of light beyond visible light had been detected. After hearing about Herschel's discovery of an invisible form of light beyond the red portion of the spectrum, Ritter decided to conduct experiments to determine if invisible light existed beyond the violet end of the spectrum as well. He had heard that blue light caused a greater reaction in silver chloride than red light did. Ritter decided to measure the rate at which silver chloride reacted to the different colors of light. He directed sunlight through a glass prism to create a spectrum. He then placed silver chloride in each color of the spectrum and found that it showed little change in the red part of the spectrum, but darkened toward the violet end of the spectrum. Johann Ritter then decided to place silver chloride in the area just beyond the violet end of the spectrum, in a region where no sunlight was visible. To his amazement, this region showed the most intense reaction of all. This showed for the first time that an invisible form of light existed beyond the violet end of the visible spectrum. This new type of light, which Ritter called Chemical Rays, later became known as ultraviolet light or ultraviolet radiation (the word ultra means beyond).‎

Experiments and Calculations relative to physical Optics. 1804) - which gives the first really convincing evidence that the fringes are produced by interference of light waves, and giving the experimental demonstrations of the general law of Interference.These importent demonstrations served as the experimental basis for the wave hypothesis of light. - In his two first papers ""On the Theory of Light and Colours"", 1802 and ""An account of Some Cases of the Production of Colours not hitherto described"", 1802 - he only partially announced his principle of Interference, and the statement of it in ""An Account..."" was entirely hypothetical and not experimental. (Magie. Source Book in Physics gives extracts of this paper and a later paper under the head: Discovery of the interference of light, pp.308-15).Young also shows here that diffraction effects can be explained by the interference law.""The experimental basis for the wave hypothesis of light as Young formulated it was interference. The fact has already been observed that two trauins of water waves may be so superposed that in certain regions the throughs of one train will lie continuously on the crests of another, thereby producing zero disturbance...Destryctive interference is said to occur between the two trains of waves in the former case and constructivee interference in lthe latter. Similarly, two sound waves may be so combined as to produce alternate regions of silence and enhanced sound. The phenomenon of interference, of which the forgoing are familiar examples, is easely comprehensible in the case of combining waves, but would be utterly incomprehensible in the case of combining streams of particles. So when Young demonstrated that two beams of light could, under properly controlled conditions be made to combine in such a way as to produce alternate regions of darkness and light, he was rightly considered to have identified in light a characteristic property of waves."" (Lloyd Taylor in: Physics. The Pioneer Science. p. 511).Of the three papers published in the years 1802-04 the last is the most importent as it gives the experimental demonstrations of the interference of light.
