""Arago .... made several important contributions to electromagnetism on his own. On 20 September 1820 he announced the discovery of the temporary magnetization of soft iron by an electric current, which suggested to Ampère a theory about the nature of magnetic ""currents"" and provided the technological key to the electric telegraph. Ampère calculated that the magnetic power could be multiplied by twisting the current-carrying wire into a helix, and with Arago he carried out the first experiments on primitive solenoids. In his historical articles Arago was always careful to credit Ampère with the major share of this discovery, which ultimately depended upon Ampère’s mathematical theory.""(DSB).Arago formed a close freinship with Fresnel,whose views on the nature of light he ardently supported. He assisted Fresnel in some of his most importent work and made original discoveries in the same field.Magie ""A Source Book in Physics"", p. 443 ff.‎

Follwing the discovery of X-rays by Röntgen, Bexquerel investigated fluorescent materials to see if they also emitted X-rays. He exposed a fluorescent uranium salt, pechblende, to light and then placed it on a wrapped photographic plate.He found that a faint image was left on the plate, which he believed was due to the pichblende emitting the light it had absorbed as a more penetrating radiation.. However, by chace, he left a sample that had not been exposed to light on top of a photographic plate in a drawer. he noticed that the photographic plate also had a a faint image of the pechblende. After several chemical tests he concluded that these ""Becquerel rays"" were a property of atoms. He had, by chace, discovered radio-activity and prompted thee beginning of the nuclear age. He shared the Nobel Prize for Physics in 1903 with Marie and Pierre Curie. The ""Becquerel Rays"" were later discovered to be a composite of three forms of emanation, distinguished by Rutherford as alpha, beta and gamma rays.Dibner: 163 (the later Mémoire from 1903) - PMM: 393 (1903- Mémoire) - Garrison & Morton: 2001 (only the first paper). - Magie ""A Sourve Book in Physics"" p. 610 ff. - Norman:157.‎

These 3 papers were extended to form his doctoral thesis of 1924 ""Recherches sur la Théorie des Quanta."" - This English edition (of the papers) was published before his thesis of 1924 as the paper is dated October 1, 1923, and published here in the Februar issue of Philosophical Magazine, months before the thesis.The English version contains furthermore an addition, a postscript, which contains a generalization of the theory which is consistent with the special theory of relativity, and NOT published in ""Comptes Rendues"" in 1923.With the three communications to the Academy of Sciences (the 3 Comptes Rendus papers) in the fall of 1923 de Broglie had presented the main ideas of his unified dynamics of light quanta and atoms. He was confident enough about his results that he submitted them also in English in the offered paper. At the end of the paper he summarized his results.

(Printing and the Mind of Man, 417).This volume of Philosophical Magazine contains another importent paper in the history of Quantum Mechanics"": ""The Quantum Theory of Radiation"" by BOHR, KRAMERS AND SLATER, pp. 785-802. ""After Kramers had succeeded in extending the scope of the correspondence argument to the theory of optical dispersion ""thus rounding off a treatment of the interaction of atomic systems with radiation that accounted for all emission, absorption, and scattering processes"" Bohr ventured to propose a systematic formulation of the whole theory, in which what he called the virtual character of the classical model was emphasized. In this he was aided by Kramers and a young American visitor, J. C. Slater, and the new theory was published in 1924 under the authorship of all three. The most striking feature of this remarkable paper, ""The Quantum Theory of Radiation,"" was the renunciation of the classical form of causality in favor of a purely statistical description. Even the distribution of energy and momentum between the radiation field and the ""virtual oscillators"" constituting the atomic systems was assumed to be statistical, the conservation laws being fulfilled only on the average. This was going too far: the paper was hardly in print before A. H. Compton and A. W. Simon had established by direct experiment the strict conservation of energy and momentum in an individual process of interaction between atom and radiation. Nevertheless, this short-lived attempt exerted a profound influence on the course of events"" what remained after its failure was the conviction that the classical mode of description of the atomic processes had to be entirely relinquished.""

This phenomena was called the ""Compton Effect"" in his honour. For this discovery Compton received the Nobel prize in physics in 1927.""Compton was able to account for this (lenghtening of wavelenght) by presuming that a photon of light struch an electron, which recoiled, subtracting some energy from the photon and therefore increasing its wavelenght. This made it seem that a photon acted as a particle: thus after more than a century, the particulate natuer of light, as evolved by Newton, was revived... What itamounted to was that Compton brought to fruition the view that electromagnetic radiation had both a wave aspect and a particle aspect, and that the aspect which was most evident depended on how the radiation was tested. De Broglie was, at the same time, showing that this held true also for ordinary particles, such as electrons.""

‎First appearance of this seminal paper in which artificial radioactivity was announced for the first time. Curie and Joliot were awarded the Nobel Prize in Chemistry 1935 ""in recognition of their synthesis of new radioactive elements"".""Until this date (1934), atomic nuclei emitting radiation were found in nature: it was called the natural radioactivity. It had been known since Rutherford that this natural radioactivity changed a nucleus into an other one: for instance radium becomes finally lead after many radioactive decays. We could say that lead does not become gold but gold becomes lead! But... this change of matter was not under control. It was not possible to construct the desired chemical element as the alchemist dreamed... But Irene and Frederic Joliot-Curie, made the dream become almost reality.""""Another very important development in the early 1934 by the Joliot-Curies in connection with irradiation of aluminum by alpha particles. The two French scientists detected the production of the recently discovered positrons. [...] However, they soon realized that the positron activity continued after the alpha source was removed and that they had, in fact, discovered positive beta radioactivity. The importance of the discovery of artificial radioactivity was immediately recognized and resulted in a Nobel Prize in chemistry to the Joliot-Curies in 1935. The new phenomenon immediately became widely employed in nuclear physics, chemistry, biology, and medicine."" (Kragh, Quantum Generations, p. 187)""These elegant experiments, which provided the first chemical proof of induced transmutations and showed the possibility of artificially creating radioisotopes of known stable elements, were repeated and extended in the major nuclear physics laboratories of various countries "" (DSB).Born on 12 September 1897 in Paris, Irène Curie was the daughter of Pierre and Marie Curie. ""During World War I, she worked as a nurse, helping her mother operate radiography equipment, and then studied physics and mathematics at the Sorbonne, gaining a doctorate for studying the range of alpha particles. She then went to work for her mother at the Radium Institute. There she met Frédéric Joliot whom she married in 1926. Frédéric Joliot was born on 19 March 1900 in Paris - He joined the Radium Institute in 1925 and obtained his PhD in 1930. Together the Joliot-Curies worked on radioactivity and the transmutation of the elements. Twice they just missed major discoveries: in 1932 when Chadwick beat them to the neutron, and in 1933 when Anderson discovered the positron. However, in 1934, whilst bombarding light elements with alpha particles, the Joliot-Curies noticed that, although proton production stopped when the alpha particle bombardment stopped, another form of radiation continued. The alpha particles had produced an isotope of phosphorus not found in nature. This isotope was radioactive and was decaying through beta-decay"" (DSB).‎

First, on the nature of the metals of the fixed alkalis. Second, on the nature of Hydrogen and composition of ammonia. Thirdly, on the metals of the earth"" and Fourthly he makes a comparison between the antiphlogistic doctrine, and a modified phlogistic hypothesis.""(Abstract). He further gives arguments for considering potassium and sodium, which he discovered in 1808, as a element.""Humphry Davy was one of the most brilliant chemists of the early nineteenth century. His early study of nitrous oxide brought him his first reputation, but his later and most importent investigations were devoted to electrochemistry. Following Galvani's experiments and the discovery of the voltaic pile, interest in galvanic electricity had become widespread. The first electrolysis by means of the pile was carried out in 1800 by Nicholson and Carisle, who obtained oxygen and hydrogen from water. Davy began to examine the chemical effects of electricity in 1800, and his numerous discoveries were presented in his Bakerian lectures."" - Wheeler Gift: 2518.‎

‎First edition in French (the first English 1808) of this importent historical paper in chemistry, in which Davy shows that electricity is capable of decomposing some alkalies, isolating two new substances and discovering potassium and sodium. Neville in his Historical Chemical Library vol. I, p.340, writes about this paper ""ONE OF THE GREAT CLASSIC RESEARCHES IN CHEMISTRY, in which Davy announced in this, his second Bakterian lecture, the isloation of metallic potassium and sodium by the electrolytic decomposition of their fused oxides.""""He (Davy) began his own electrical experiments...The results were spectacular. On October 6, 1807, the current passing through molten potash liberated a metal, which Davy called potassium. The little globules of shining metal tore the water molecule apart as it eagerly recombined with oxygen and the liberated hydrogen burst into lavender flame. Davy danced about in a delirium of joy. A week later he isolated sodium from soda.""(Asimow). The paper offered here describes these discoveries.""Humphry Davy was one of the most brilliant chemists of the early nineteenth century.

‎First appearance of these milestone papers in the histroy of electricity in which Dufay explains his discovery of two kinds of electricity and the relation between them, attraction and repulsion, shocks and sparking, and the full recognition of electrostatic repulsion. He formulates the two-fluid theory of electricity. He further showed that ""not all bodies can become electrified themselves"" (by friction) and went on to show, ""that they can all acquire a considerable (electrical) virtue when the tube (of rubbed) glass), wood, metals or liquids are brought near them,"", provided only that they are insulated by beiing stood on ""a support of glass or of sealing-wax"".Dufay ""TRANSFORMED A COLLECTION OF MISCELLANEOUS WEEDS INTO THE FIRST GARDEN OF EUROPE"" (Heilbron)""Dufay's substantive discoveries - ACR, the two electricities, shocks and sparking - are but one aspect, and perhaps not the most significant, of his achievement. His insistence on the impiortence of the subject, on the universal character of electricity, on the necessity of organizing, digesting and regulariizing known facts before grasping new ones, all helped to introduce order and professionel standards into the study of electricity at precisely the moment when the accumulation of data began to require them. He foundthe subject a record of often capricious, disconnected phenomena, the domain of the polymaths, textbook writers, and prfesional lecturers, and left a body of knowledge that invited and rewarded prolonged scrutinity from serious physicists.""

‎First printing of Faraday's famous letter to Gay-Lussac in which he claim to be the discoverer of electro-magnetic induction, analysed the results of the Italian philosophers, pointing out their errors, and defending himself from what he regarded as imputations on his character. The style of this letter is unexceptionable, for Faraday could not write otherwise than as a gentleman"" but the letter shows that had he willed it he could have hit hard. The letter was later translated into English and published in ""Philosophical Magazine"" in 1840 under the title ""On Magneto-electric Induction"".""In 1831, seemingly out of nowhere, came the discovery of electromagnetic induction and the beginning of the experimental researches in electricity which were to lead Faraday to the discovery of the laws of electrochemistry, specific inductive capacity, the Faraday effect, and the foundations of classical field theory.""
