‎First printing of the paper in which Airy describes his remarkable experiments aiming at finding the density of the earth. His approach to the problem was to determine the differences of gravity at the top as well at the bottom of a suitable deep mine.""One of the most remarkable of Airy's researches was his determination of the mean density of the Earth. In 1826, the idea occurred to him of attacking this problem by means of pendulum experiments at the top and bottom of a deep mine. His first attempt, made in the same year, at the Dolcoath mine in Cornwall, failed in consequence of an accident to one of the pendulums. A second attempt in 1828 was defeated by a flooding of the mine, and many years elapsed before another opportunity presented itself. The experiments eventually took place at the Harton pit near South Shields in 1854. Their immediate result was to show that gravity at the bottom of the mine exceeded that at the top by 1/19286 of its amount, the depth being 383 m (1,256 ft) From this he was led to the final value of Earth's specific density of 6.566.[This value, although considerably in excess of that previously found by different methods, was held by Airy, from the care and completeness with which the observations were carried out and discussed, to be ""entitled to compete with the others on, at least, equal terms."" (The currently accepted value for Earth's density is 5.5153 g/cm.). (Wikipedia).‎

(Horblit: 100 - Dibner: 62).""From 1814 until 1820 Ampére did not perform the kind of research that would have made it into the annals of the histrory of science, but on September 11, 1820 when he heard Francois Arago speak about Oersted's work, he got fresh inspiration and started the work that made him famous. Arago related how Oersted had found that a steady electric current influences the orientation of a compass needle. After a weak Ampère had determined experimentally that that two straight, parallel, and current-carrying, wires execute a force on each other. The magnitude of the force is inversely proportional to the distance between the wires and proportional to the strenghts of the current..... During the following years he continued his researches, both experimentally and theoretically. he built an instrument for measuring electricity that later was developed into the galvanometer. Finally in 1825 he presented his collected results to the Academy IN ONE OF THE MOST CELEBRATED MEMOIRS IN THE HISTORY OF NATURAL PHILOSOPHY (The paper offered).""

The Difference Engine No.2...is entirely described by its aid."" .Babbage considered his mechanical notation system to be one of his finest inventions, and thought it should be widely implemented. It was a source of frustartion to him, that no other machine designerr adopted it (probably because no ther engineer during Babbage's time attermpted to build machines as logically and mechanically complex as Babbage's.

‎First appearance of the paper in which Babinet expounds his importent law, stating the formula that holds between diffraction and diffraction pattern in optics. The principle plays an important role in antenna design and Babinet’s principle is particularly interesting to consider in this case where the metasurfaces and their complements can be regarded as variations on a folded dipole antenna array and patch antenna array, respectively. Babinet was together with Fresnel one of the pioneers in the development of the new optics, the wave-theory of light.""An early proponent of the wave theory of light which had recently been perfected by Fresnel and Young, Babinet devoted much of his research to extending its applications. His first published paper on optics. ""Sur les couleurs des réseaux,"" dealt with Fraunhofer’s discovery that white light viewed through a wire grating produces a series of continuous spectra. Babinet derived the formula that relates the deviation of rays of a given color to the ratio of their wavelength divided by the sum of the diameter of the wires plus the distance between any two wires. He also showed that diffraction experiments could yield an improved measure of wavelengths and presented a table of new values.Babinet realized that the grating was only one of a number of means of producing diffraction effects, so he extended his theoretical work to include other systems. The result was a concept known today as Babinet’s principle: ""If parallel rays fall normally on a diffraction system formed from a large number of openings... the diffraction phenomena will remain identically the same if the transparent parts become opaque, and reciprocally.""(DSB).‎

‎First printing of an importent paper in the history of photochemistry as he here discovered some effects of coloured rays of the solar spectrum.""Edmund Becquerel seems to be the first person to observe, in 1840 (in the paper offered), that the latent daguerreotype image which had been underexposed could be intensified if re-exposed to the yellow and red rays of the spectrum and then developed with mercury... Explaining this phenomenon, Becquerel called the yellow-red continuing rays (""rayon continuateurs"") in contrast to the primary rays, which exicited or produced the light image and which he called exiciting rays (""rayons excitateurs"").... They are dependent on the wave lenght of the light.""(Eder ""History of Photography"", pp. 265 ff.)""Becquerel was an early experimenter in photography. In 1840 he discovered that the silver halides, natively insensitive to red and yellow light, became sensitive to that part of the spectrum in proportion to their exposure to blue, violet and ultraviolet light, allowing Daguerreotypes and other photographic materials to be developed by bathing in strong red or yellow light rather than by chemical treatment. In practice this technique was rarely used."" (Wikipedia).‎

‎"BECQUEREL, EDMOND. - THE BEGINNING OF SOLAR-CELL-ENERGY.‎

‎Sur les effets électriques qui se produisent sous l'influence solaire.‎

‎(Paris, Bachelier), 1839. 4to. No wrappers. In: ""Comptes Rendus Hebdomadaires des Séances de L'Academie des Sciences"", Tome IX (No.22). Entire issue offered. Becquerel's paper: pp. 711-713.‎

‎First printing of this important paper, which together with Becquerel's paper ""Mémoire sur les effets èlectriques produits sous l'influence des rayons solaires"" and ""Recherches sur les effets de la radiation chimique de la lumière solaire, au moyen des courants électriques"", published the same year, marks the beginning of Solar-Cell-Energy, the first step in a long path to solar panels, and a technology of immense importence for humanity. In 1923 Albert Einstein received the Nobel Prize for his theories explaining the photoelectric effect (his 1905-paper).The ""photovoltaic effect"" is the basic physical process through which a solar cell converts sunlight into electricity. In 1839, nineteen-year-old Edmund Becquerel, a French experimental physicist, discovered the photovoltaic effect while experimenting with an electrolytic cell made up of two metal electrodes. Becquerel found that certain materials would produce small amounts of electric current when exposed to light.‎

‎First edition of Henri Becquerel's importent study of the magnetic substances in which he sets forth his discovery that ""the magnetic rotation of the bodies is connected with their refractive index and with another function that varies with their specific magnetism"". For the first time it was showed that there is a connexion between the rotatory power and the magnetic properties of matter.The volume contains other importent papers, more than 10 papers by , MARCELLIN BERTHELOT, mainly on Thermo-Chemistry.‎
