He spelled out the fundamental tenets to his approach in 1875: (Weber’s law was incorrect for the case where only one kind of electricity is assumed to move, since the equation entails that a current exert a force on a charge at rest" (2) a revision would be possible if one assumed that the electrodynamic action occurred via an intervening medium, for then electric particles that are not moving relative to each other (moving at equal velocities) could still exert forces on one another by virtue of their absolute motion in the medium" forces should not be restricted to the line joining two charges. In 1876 Clausius simplified the equation he had previously proposed by subjecting it to the condition of the conservation of energy. In doing so, however, he ignored the possibility that energy changes might occur in the intervening medium.""(DSB).‎

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.

‎First printing of this monumental memoir (the invention of the TORSION BALANCE) dealing with the best way to construct a magnetic compass. The paper contains the design of a torsion suspension declination compass and the demonstration that the forces of torsion is proportional to the angle of twist. Coulomb received the prize awarded by the Academy for this paper drafted by the Academy in 1777 (he shared the prize with Van Swinden). - ""The importance of this memoir for Coulomb's career is that it CONTAINED ELEMENTS OF ALL HIS MAJOR PHYSICAL STUDIES: the quantitative study of magnetism, torsion and the torsion balance, friction and fluid resistance, and the germ of his theories of elasticity and magnetism.""(DSB).""Coulomb’s first writings on torsion were presented in his Academy prize-winning memoir of 1777, ""Recherches sur la meilleure maniere de fabriquer les aiguilles aimantées.""......... his simple, elegant solution to the problem of torsion in cylinders and his use of the torsion balance in physical applications were important to numerous physicists in succeeding years. In chapter 3, Coulomb developed the theory of torsion in thin silk and hair threads. Here he was the first to show how the torsion suspension could provide physicists with a method of accurately measuring extremely small forces. He showed that within certain angular limits, torsional oscillation consisted of simple harmonic motion. He examined the parameters relating the angle of twist to the length, diameter, and elastic properties of the torsion thread. In the range of simple harmonic oscillation Coulomb demonstrated that the force of torsion was proportional to the angle of twist. He used this principle in measuring small magnetic forces and also called attention to its use in measuring other forces, notably those of fluids in motion. Eventually he was able to measure forces of less than 9 x 10-4 dynes.""""Coulomb’s major memoirs in electricity and magnetism are his 1777 memoir on magnetic compasses, the famous series of seven electricity and magnetism memoirs read at the Academy from 1785 to 1791, and several magnetism memoirs prepared after the French Revolution. In his electrical studies Coulomb determined the quantitative force law, gave the notion of electrical mass, and studied charge leakage and the surface distribution of charge on conducting bodies. In magnetism he determined the quantitative force law, created a theory of magnetism based on molecular polarization, and introduced the idea of demagnetization (basically, that combinations of magnetic poles can ""cancel"" each other).""(DSB).Parkinson ""Breakthroughs"": 1777:P‎

It was his view, expressed between 1898 and 1900, that the source of activity was external to the radioactive element. He imagined that radium, say, had the ability to act as a Maxwellian demon and select from the atmosphere those air particles which were moving more swiftly than the average, absorb some of their energy, and eject them at a lower speed. This theory, which never received full publication, contravened the second law of thermodynamics"" and although Crookes thought that he might have experimental support for it, his evidence did not measure up to the critical scrutiny of Stokes.""

No one before M. Charles Cros had thought of reproducing sound by making an apparatus capable of registering and reproducing sounds which had been engraved with a diaphragm. The inventor gave the name of Paleophone (voix du passé) to his invention. On April 30, 1877 he submitted a sealed envelope containing a letter to the Academy of Sciences in Paris explaining his proposed method. The letter stated in French, ""Alors qu'il séjourne à Sablé au début de 1877, Charles Cros rédige une courte note, « Procédé d'enregistrement et de reproduction des phénomènes perçus par l'ouïe », dans laquelle il expose le principe de ce qu'il nomme « Paléophone » (« voix du passé ») : « Un index léger est solidaire du centre de figure d'une membrane vibrante "" il se termine par une pointe [...] qui repose sur une surface noircie à la flamme."" The English translation is one close to this: ""A lightweight index is fixed to the center of figure of a vibrating membrane, it ends with a tip [...] based on a blackened surface flame. This surface is integral with a disc driven by a double movement of rotation and linear progression. The system is reversible: when the tip makes ironing in the furrow membrane restores the original acoustic signal."" The letter was read in public on 3 December following. In his letter, after having shown that his method consisted of detecting an oscillation of a membrane and using the tracing to reproduce the oscillation with respect to its duration and intensity. Cros added that a cylindrical form for the receiving apparatus seemed to him to be the most practical, as it allowed for the graphic inscription of the vibrations by means of a very fine-threaded screw.""(Wikipedia)‎

‎First printing of this milestone paper, being the first ""Note"" from Marie Curie about ""radioactivity"". This same ""Note"" contains a the fundamental observation: ""Two uranium ores... are much more active than uranium itself. This fact... leads one to believe that these ores may contain an element much more active than uranium."" This paper gives the first proof of the fact that radiation is an atomic property.""Henri Becquerel, discovered (1896) that uranium salts shielded from light for several months spontaneously emit rays related in their effects to Roentgen rays. Mme. Curie became enthusiastic about this subject filled with the unknown and, as she later acknowledged, involving no bibliographic research.The first step in the research was to determine whether there existed other elements capable, like uranium, of emitting radiation. Abandoning the idea of hyperfluorescence, couldn’t one calculate by electrical measurement the effects on the conductivity of air that were revealed by the gold-leaf electroscope? Pierre Curie and his brother Jacques had constructed an extremely sensitive apparatus to measure weak currents"" Mme. Curie employed it in testing both pure substances and various ores. In her first ""Note"" in the Comptes rendus""de l Académie des sciences (12 April 1898) she described the method that she followed throughout her life, the method that enabled her to make comparisons through time and crosschecks with other techniques:""I employed... a plate condenser, one of the plates being covered with a uniform layer of uranium or of another finely pulverized substance [(diameter of the plates, eight centimeters"" distance between them, three centimeters). A potential difference of 100 volts was established between the plates.]. The current that traversed the condenser was measured in absolute value by means of an electrometer and a piezoelectric quartz. In general she preferred the zero method, in which the operator compensates for the current created by the active material by manipulating the quartz. All of her students followed this procedure.""(DSB).The first results came in 1898: the measurements varied between 83 × 10-12 amperes for pitch blende to less than 0.3 × 10-12 for almost inactive salts, passing through 53 × 10-12 for thorium oxide and for chalcolite (double phosphate of uranium and copper). Thorium would thus be ""radioactive"" (the term is Mme. Curie’s" its radioactive properties were discovered at the same time, independently, by Schmidt in Germany.‎

‎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 came the announcement in 1899 by Marie Curie of induced radioactivity, brought about by the action of polonium or radium on inactive substances. The induced radioactivity persisted over a considerable period of time, a phenomenon of great concern to Pierre Curie. He took up the question with Debierne, with whom he published two papers in 1901(the first two papers offered)"" their experiments could be explained by Rutherford’s theory of emanation (radon), a radioactive gas emitted by radium. With J. Danne, Curie measured the diffusion coefficient of radium emanation in the air and proved, as Rutherford had done, that it liquefies at - 150°C. In order to clarify the nature of the emanation he studied the law of diminution of the activity of a solid after having removed it from a chamber in which a radium salt was present. In two notes presented to the Academy on 17 November 1902 and 26 January 1903 (the third and fourth papers offered), Curie showed that this activity diminishes according to an exponential law characterized by a time constant that, for the emanation, is equal to 5,752 days, regardless of the conditions of the experiment. The importance of this discovery, which marks the point of departure for all modern measurements of archaeological and geological dating, did not escape his, for at a meeting of the Société Française de Physidque in 1902 he defined a standard for the absolute measurement of time on the basis of radioactivity. Almost immediately Rutherford and Soddy showed that the exponential diminution was caused by the transmutation of radioactive elements."" (DSB. Pierre Curie).‎

‎First printing of probably the first (in the Juillet issue of Annales) official announcement of Daguerre's invention of the photographic process. The paper offered here preceeded the official report in Comptes Rendues which was published at the end of 1839 (in the July-December issue). The first report of on the discovery was presented to the Royal Academy on January 7, 1839 and delivered in full on August 19, 1839 (and printed in the July-Dec. issue of Comptes Rendues). The paper also preceeded Daguerre's own publication of 1839 ""Historique et description du daguerréotypie...""In 1839 Arago took a personal interest in announcing and popularizing the inventions of Niepce and Daguerre, who were awarded government pensions as a result of Arago’s recognition of their inventions’ potential significance.""In 1829 Daguerre went into partnership with Niepce, who had managed to produce images by the action of light some three years earlier but had failed to make the process really practical. Daguerre carried on and began to use copper plates on which silver salts were deposited. ight was made to focus upon that and an image was formed. The light portions of the image darkened the salts, while the shadowy portions left them unaffected. The unchanged salt was dissolved away by sodium thiosulfate (a process that had been suggested by John Herschel and a permanent image of sorts was left behind.""(Asimov).‎

‎First appearance of Daniell's first paper on the construction of the famous ""Daniell-Cell"", in which he announced his invention of the battery, THE FIRST RELIABLE SOURCE OF AN ELECTRIC CURRENT. In the new invention by Charles Wheatstone of the electric telegraph in 1837, the Daniell cell was used as the electric source.In 1831 Daniell was appointed profesor of Chemistry at King's College London. He invented several scientific instruments, including a hygrometer for measuring humidity he is best known for his work in electrochemistry, his interests having been aroused by the work of his good friend Faraday. Volta's battery had the defect of rapid diminution in current. What was needed, however, was a battery yielding a constant current over a considerable lenght of time. In 1836 Daniell succeeded, producing the Daniell cell, of copper and zinc. his was the first reliable source of electric current.Parkinson ""Breakthroughs"" 1836 P.‎

That many of his conclusions are now out of date should in no way diminish the historical interest in his experiments, nor the importent service thet he rendered cosmogony by the example he gave of putting various hypotheses to the test of actual calculations. Darwin's method remains a milestone in the development of cosmogony, and subsequent investigators have favored it over the merely qualitative arguments prevalent until that time.""(DSB).‎
