‎First apperarance of this paper, constituting the first reliable account of colour blindness.Usually Goethe or John Dalton - Huddart's case was cited in Dalton's paper of 1794 - is supposed to have discovered colourblindness. However, the English oculist Joseph Huddart was the discoverer of this phenomenon. The first physiological explanation of it does come from Goethe.Garrison & Morton: 5832.‎

‎First appearance of the six landmark papers in which Becquerel documents his discovery of Radio-activity, PROMPTING THE NUCLEAR AGE.Becquerel was an expert in fluorescence and phosphorescence, continuing the work of his father and grandfather. 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.‎

‎A Tentative Theory of Light Quanta.‎

‎London, Taylor and Francis, 1924. Later full buckram, gilt lettering to spine. In: Philosophical Magazine conducted by Oliver Joseph Lodge etc."", Vol. 47. - Sixth Series. VIII,1168 pp. and 8 plates. (Entire volume offered). De Broglie's paper: pp. 446-458. Internally clean and fine.‎

‎First English version of the papers which ESTABLISHED A NEW ERA IN PHYSICS by introducing the epochal new principle that particle-wave duality should apply not only to radiation but also to matter and thus CREATING QUANTUM MECHANICS. The English paper is a translation of de Broglie's 3 ""Notes "" which he published in ""Comptes Rendus"" in September and October 1923 (Ondes et quanta. - Quanta de lumière, diffraction et interférences. - Les quanta, la théorie cinétique des gaz et le principe de Fermat). 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. De Broglie relates ""After long reflection in solitude and meditation, I suddenly had the idea, during the year 1923, that the discovery made by Einstein in 1905 should be generalized by extending it to all material particles and notably to electrons"" (Preface to his PhD thesis 1924).""He made the leap in his September 10, 1923, paper: E=hv should hold not only for photons but also for electrons, to which he assigns a 'fictitious associated wave'. In his September 24 paper, he indicated the direction in which one 'should seek experimental confirmations of our ideas': a stream of electrons traversing an aperture whose dimensions are small compared with the wavelenght of the electron waves 'should show diffraction phenomena' .""(Pais ""Subtle is the Lord"", pp. 425-436).In the third paper (October 8) he discusses ""The interplay between the propagation of the particle and of the waves could be expressed in more formal terms as an identity between the fundamental variational principles of Pierre de Fermat (rays), and Pierre Louis Maupertuis (particles) as de Broglie discussed it further in his last communication . Therein he also considered some thermodynamic consequences of his generalized wave-particle duality. He showed in particular how one could, using Lord Rayleigh’s 1900 formula for the number of stationary modes for phase waves, obtain Planck’s division of the mechanical phase space into quantum cells.Louis de Broglie achieved a worldwide reputation for his discovery of the wave theory of matter, for which he received the Nobel Prize for physics in 1929. His work was extended into a full-fledged wave mechanics by Erwin Schrödinger and thus contributed to the creation of quantum mechanics. After an early attempt to propose a deterministic interpretation of his theory, de Broglie joined the Copenhagen school’s mainstream noncausal interpretation of the quantum theory.""(DSB).""This idea [i.e. de Broglie's that matter might behave as waves] was tested and confirmed by Davisson and Germer in 1927... Thus the duality of both light and matter had been established, and physicists had to come to terms with fundamental particles which defied simple theories and demanded two sets of 'complementary' descriptions, each applicable under certain circumstances, but incompatible with one another."" (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.""

‎First printing of this importent paper, the first to describe in detail how the phenomena of Self-Induction was discovered. Henry discovered the induction phenomena - how an electric current in one coil may set up a current in the other through the development of the magnetic field - independently of Faraday, but Faraday was first to publish on electromagnetic induction. Henry's experiments with induction led him to his importent discovery of SELF-INDUCTION, which is the phenomenon in which a change in electric current in a coil produces an induced emf in the coil itself. This phenomenon was also discovered inependently by Faraday, but this time Henry had published first. The basic unit of inductance was to be called ""the Henry"". Relevant to the controversy between Faraday and Henry is the following statement by A D Bache, Secretary of the American Philosophical Society introducing an abstract of Henry in J Franklyn Inst. 1835 pp. 169-70 (H. Norman 1053 and the paper offerd): ""A memoir on this subject has been since submitted to the Society, containing an extension of the subject, the primary fact in relation to which was observed by Professor Henry as early as 1832, and announced by him in the American Journal of Science. Mr. Faraday having recently entered upon a similar train of observations, the immediate publication of the accompanying is important, that the prior claims of our fellow countryman may not be overlooked.""(Spark Museum).Magee ""Source Book in Physics"", p. 515.‎

Raoult published his results on the effects of nondissociating organic solutes, from which he deduced a general law controlling the lowering of freezing points (the first paper offered). Four years later he extended this work to show the effect of solutes on vapor pressure (the second paper offered). Having established the effect of nondissociating compounds, he was in position to show that salts produced an eeffect which, though anomalous, could nevertheless be explained by the supposition that a dissolved molecule broke up into other molecules. This work was of great value in supplying a new method for determining molecular weights, since the depression of freezing point and vapor pressure (as well a the related rise in boiling point later discovered) are proportional to the moleculat concentrations ofthe solutions"" it was of equal value in supporting the ideas of van't Hoff on osmotic pressure. With the announcement of the dissociation theory of Arrhenius, the anomalies were explained and the full significance of the generalizations of Raoult was recognized.

‎First printing of this milestone paper in quantum physics in which Compton verifies Planck's quantum postulate and found that some of the X-rays had, in scattering, lenghtened their wavelenght. 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 printing of the paper in which Berry describes his discovery of the ""Berry phase"", a unifying concept in quantum mechanics.""In 1983, Berry made the surprising discovery that a quantum system adiabatically transported round a closed circuit in the space of external parameters acquires, besides the familiar dynamical phase, a non-integrable phase depending only on the geometry of the circuit. This Berry phase, which had been overlooked for more than half a century, provides us a very deep insight on the geometric structure of quantum mechanics and gives rise to various observable effects. The concept of the Berry phase has now become a central unifying concept in quantum mechanics, with applications in fields ranging from chemistry to condensed matter physics. In particular, the Berry phase plays an important role in modern magnetism, an allows to reach a deeper understanding of a broad range of phenomena such as the spin-orbit coupling, the Aharonov-Bohm effect, the quantum Hall effect, the anomalous Hall effect, the magnon dynamics, the tunneling of magnetization in molecular magnets, etc. Further, in the light of the Berry phase, a number of new phenomena can be predicted in ferromagnets with a textured magnetization or in semiconductors with spin-orbit coupling.""

He then combined induction proper (using Faraday’s findings and his own) with selfinduction to show how these produce a pattern of repulsions yielding an increased effect in spirals. He specifically linked these “magneto-electrical” results to the principles of static induction developed by Cavendish and Poisson. This explanation was then applied to Savary’s report of changes of polarity when magnetic needles were placed at varying distances from a wire in which a current was being transmitted (""Mémoire sur l’aimantation,"" in Annales de chimie et de physique, 34 [1827],.

Two days later he made a more remarkable discovery. It had occurred to him that perhaps thetransformation of amygdalin could be effected by the albumin in the almonds, in a manner similar to the action of yeast in sugar...Wöhler suspected that the decomposition was an example of what Berzelius had recently defined as catalysis. Liebig and Wöhler then divided up the detailed examination of the properties and composition of amygdalin.

‎First apperance of Villard's two papers in which he announced and described the discovery of a new type of radiation more powerfull and penetrating than alpha-and beta rays. The new type of rays was named by Rutherford as gammarays.""His (Villard)experiments in radioactivity led to the unexpected discovery of gamma rays in 1900. Villard recognized them as being different from x rays because the gamma rays had a much greater penetrating depth. He had discovered they were emitted from radioactive substances and were not affected by electric or magnetic fields. These came to be called gamma rays by another scientist, Ernest Rutherford. It wasn't until 1914 that Rutherford showed that they were a form of electromagnetic (EM) like light only with a much shorter wavelength than x rays. Now we know that gamma rays are a form of EM radiation similar to x rays. Gamma rays tend to have a higher energy and a shorter wavelength than x rays do. However, the dividing line between these two forms of radiation is not clearly defined. Scientists typically apply the term gamma ray to EM radiation with energies above several hundred thousand electron volts.""

With oxygen, he always obtained the same density, regardless of how the oxygen might be produced, whether from one particular compound, from a second compound, or from the air. The situation was different with nitrogen. The nitrogen he obtained from air constantly showed a slightly higher density than the nitrogen he obtained from any of various compounds. Rayleigh could think of several ways in which the nitrogen obtained from air might be contaminated but none of the possibilities checked out experimentally. He was so frustrated that he went so far as to write to the journal ""Nature"" asking for suggestions. Ramsay, a brilliant Scottish chemist, asked permission to tackle the problem and received it. The upshot was that a new gas, somewhat denser that nitrogen, was discovered to exist in the atmosphere. It was named argon and it was the first of a series of rare gases of unusual properties whose existence had never been suspected.""(Asimow).Dibner, Heralds of Science No. 50 - Neville, Historical Chemical Library vol.

The two crystals resembled each other as a right-hand glove resembles a left-hand glove....This was a revolutionary discovery and it took some courage to announce it. A few years before, the well-known chemist Mitscherlich had studies the same tartrate crystals and declared them all to be identical. Pasteur was only a twenty-sic-year-old unknown. neverthelless he announced his findings and went before Biot to repeat the separation ofthe crystals before the eyes of the aged authority in the field. Biot was convinced and Pasteur received the Rumford medal of the Royal Society for his work....Pasteur had thus founded the science of polarimetry in which the measurements of the manner in which the plane of polarized light was twisted could be used to help to determine the structure of organic substance, to follow various chemical reactions, and so on.""(Asimov).

‎First appearance of the landmark papers in which Becquerel documents his discovery of Radio-activity, PROMPTING THE NUCLEAR AGE, and the papers which the Curies announced the discoveries of the 2 elements Polonium and Radium.Becquerel was an expert in fluorescence and phosphorescence, continuing the work of his father and grandfather. 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. ""The Curie's owned their success to an extremely sensitive electroscopic apparatus constructed by Pierre and his brother Jacques, which made possible a ""new method of chemical analysis based on the precise measurement of radium emitted, a method still in use.""(DSB).Becquerel's discovery of the radioactive properties of uranium (1896) inspired Marie and Pierre Curie to investigate radiation. They reported their researches in a series of papers from 1897 in the Comptes rendus. First they isolated a new substance about three hundred times as active as radium. This they called Polonium in honour of Marie's native Poland. A further examnination of the residue of Pitchblende after the removal of uranium and polonium disclosed residual radio-activity far greater than was possessed by either substance alone. To this material the name Radium was given. The radium was found to be about two million times as radio-active as uranium.Garrison & Morton: 2003. - Magie ""A Source Book in Physics"" p. 613 ff.‎

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. 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 lecture to the Royal Society on November 20, 1806.
