Davy was chemically preparing Potassium and Sodium through an electrical current, and this made Gay-Lussac and Thénard envious of his success. They too decided to perform the same task, but they had no battery at their disposal as Davy had, so they had to form another way to chemically prepare the two elements. In 1808, they used a red-hot iron fused to potash, the water-soluble form of a manufactured salt containing potassium, to perform this task, a method that Davy admitted had its advantageous qualities. Gay-Lussac and Thénard were successful in preparing Potassium, and continued to make a full analysis of its chemical properties, and began to use it for their own experiments. In 1809, Davy performed the same task, using it to reduce Boron in Boracic acid.""‎

‎First appearance of a milestone paper in genetics being the ""REDISCOVERY"" OF MENDEL'S LAWS OF HEREDITY"" - This paper, together with the two other papers from the same year by Carl Correns and Erich Tschermak, laid the foundations of a new scientific discipline that, in 1906, was given the name ""genetics"", and less than a century later, rose to become the leading science in Western society. This French announcement was published 4 days before his longer paper ""Das Spaltungsgesetzt der Hybride"", in which Mendel is mentioned.De Vries completed most of his hybridization experiments without knowing about Mendel's work. Based on his own results, de Vries drew the same conclusions as Mendel. De Vries published his work in 1900, first in French then in German. In the French report there was no mention of Mendel, but this was amended by de Vries in the German paper. It is possible that de Vries read Mendel's paper before he published his own, and included Mendel's name in the later printing when he realized that other people also knew about Mendel's work. De Vries may have thought that his own conclusions were superior to Mendel's. ""During the 1880s, de Vries became interested in heredity. In 1889 he published Intracellular Pangenesis, in which he critically reviewed previous research on inheritance and advanced the theory that elements in the nucleus, ‘pangenes’, determine hereditary traits. To investigate his theories, he began breeding plants in 1892 and by 1896 had obtained clear evidence for the segregation of characters in the offspring of crosses in 3:1 ratios. He delayed publishing these results, proposing to include them in a larger book, but in 1900 he came across the work of Gregor Mendel, published 34 years earlier, and announced his own findings. This stimulated both Karl Correns and Erich von Tschermak-Seysenegg to publish their essentially similar observations.""

Now commonly called the Debye temperature, theta could be calculated from the elastic constants of the solid. The Debye equation, involving the then recently developed quantum theory, gave agreement with observed specific heat values.

‎First appearance of these milestone papers in Quantum Physics, constituting the first step in Quantum Field Theory and the invention of the Second Quantifization Method. By these papers Dirac ""gave the foundation for that theory, quantum electrodynamics""(Pais).""A New Radiation Theory. Dirac liked his transformation theory because it was the outcome of a planned line of research and not a fortuitous discovery. He forced his future investigations to fit it. The first results of this strategy were almost miraculous. First came his new radiation theory, in February 1927, which quantized for the first time James Clerk Maxwell’s radiation in interaction with atoms. Previous quantum-mechanical studies of radiation problems, except for Jordan’s unpopular attempt, retained purely classical fields. In late 1925 Jordan had applied Heisenberg’s rules of quantization to continuous free fields and obtained a light-quantum structure with the expected statistics (Bose Einstein) and dual fluctuation properties. Dirac further demonstrated that spontaneous emission and its characteristics—previously taken into account only by special postulates—followed from the interaction between atoms and the quantum field. Essential to this success was the fact that Dirac’s transformation theory eliminated from the interpretation of the quantum formalism every reference to classical emitted radiation, contrary to Heisenberg’s original point of view and also to Schrödinger’s concept of ? as a classical source of field.This work was done during Dirac’s visit to Copenhagen in the winter of 1927. Presumably to please Bohr, who insisted on wave-particle duality and equality, Dirac opposed the ""corpuscular point of view"" to the quantized electromagnetic ""wave point of view."" He started with a set of massless Bose particles described by symmetric ? waves in configuration space. As he discovered by’ playing with the equations, ’ this description was equivalent to a quantized Schrödinger equation in the space of one particle"" this’ second quantization’ was already known to Jordan, who during 1927 extended it into the basic modern quantum field representation of matter. Dirac limited his use of second quantization electromagnetic to radiation: to establish that the corpuscular point of view, once brought into this form, was equivalent to the wave point of view.""(DSB).‎

‎First printing of the famous paper in which Draper relates how he was able to made the first photographic portrait on a daguerreotype plate, giving an ennormously long exposure. The subject of the portrait, Draper's assistant, powdered his face with flour and sat in front of the camera for a half hour facing the sunlight.Draper stated that it is possible to make portraits in full sunlight, using mirrors as light reflectors. ""But in the reflected sunshine, the eye cannot support the effulgence of the rays. It is therefore necessary to pass them through some blue medium, which shall abstract from them their heat and take away their offensive brilliancy. Ihave used for this purpose blue glass, and also ammoniaco-sulphate of copper, contained in a large trough of plate glass, the interstice being about an inch thick."" (p. 217 in the paper offerd).""Draper first achieved wide celebrity for his pioneering work in photography. As early as 1837, while still in Virginia, he had followed the example of Wedgwood and Davy in making temporary copies of objects by the action of light on sensitized surfaces. When the details of Daguerre’s process for fixing camera images were published in various New York newspapers on 20 September 1839, Draper was ready for the greatest remaining challenge, to take a photographic portrait. A New York mechanic, Alexander S. Wolcott, apparently won the race by 7 October. But if Draper knew of this, he persisted in his own experiments and succeeded in taking a portrait not later than December 1839. His communication to the Philosophical Magazine, dated 31 March 1840, was the first report received in Europe of any photographer’s success in portraiture. The superb likeness of his sister Dorothy Catharine, taken not later than July 1840, with an exposure of sixty-five seconds, seems to be the oldest surviving photographic portrait.""(DSB).The volume contains also Michael Faraday's importent letter to Gay-Lussac on induction in the first English version.

The paper ""represents the basis of the one written by the same author in collaboration with Wolfgang Pauli in 1943, in which, by following analogous lines, the proof of the non-existence of regular particle-type solutions was generalized to the case of cilyndrical geometries in Kaluza-Klein theory (Einstein & Pauli, 1943). Besides, other generalizations were subsequently presented. The (non)-existence of such solutions in classical unified field theory was undoubtedly an important criterion leading Einstein's investigations.""Galvagno and Giribet).""In his search for a unified field theory that could undercut quantum mechanics, Einstein considered five-dimensional classical Kaluza-Klein theory. He studied this theory most intensively during the years 1938-1943. One of his primary objectives was finding a non-singular particle solution. In the full theory this search got frustrated, and in the x5-independent theory Einstein, together with Pauli, argued it would be impossible to find these structures.""

‎First editions, in the scarce offprint versions, of Einstein's last and highly important contributions to General relativity, and in which is shown that the equation of motion follows directly from the field equation that defined the geometry.""Einstein's last importent contribution to general relativity deals again with the problem of motion. It is the work done with Leopold Infeld and Banash Hoffmann on the N-body problem of motion. In these papers, the gravitational field is no longer treated as external. Instead, it and the motion of its (singular) sources are treated simultaneously. Anew approximationscheme is introduced in which the fields are no longer necessarily weak but in which the source velocities are small compared with the light velocity .... The equations obtained have found use in situations where Newtonian interaction must be included. '(These equations) are widely used in analyses of planetary orbits in the solarsystem. For example, the Cal Tech Jet Propulsion Laboratory uses them, in modified form, to calculate ephmerides for high-precision tracking of planets and spacecraft.""(Pais ""Subtle is the Lord"", p. 290-91).""The problem of the equation of motion of bodies is the following. The 1916 theory had a classical structure in the sense that there were both field equations (the curvature of space-time is determined by the mass and motion of bodies in space-time) and equations of motion of bodies (the world line of small mass is a geodesic). Are these two statements really separate? If the field equations were linear, they indeed would be. They are not linear, however, and Einstein showed (in the papers offered) that if matter is represented by a point singularity of the metric field, these singularities are located on world lines that are geodesics of space-time, provided its metric satisfies the equation of general relativity.""(DSB).Weil: 202 a. 295 (both with an asterix denoting a major paper). - Boni: 236 a. 236.1.‎

‎First edition of the first explicit statement of Einstein's energy-mass equation E=mc2.Nearly all descriptions of Einstein's scientific work state that the mass-energy equivalence E=mc2 was first formulated in Einstein's 1907 review paper 'Über das Relativitätsprinzip und die aus demselben gezogenen.' published in 'Jahrbuch der Radioaktivität und Elektronik' (see Weil no. 21 and Dictionary of Scientific Biography, vol. 4 pp.323 for examples). However, in his paper 'Über die von Relativitätsprincip geforderte Trägheit der Energie' [the offered paper] which predates the former mentioned by six months, Einstein gave a clear statement of the mass-energy equivalence E=mc2. See Lanczos: The Einstein Decade, pp.149-150 and 153 as well as Volume 2 of 'The Collected Papers of Albert Einstein' pp. 428.Einstein's first paper regarding the relation E=mc2 is his fourth 1905 paper, 'Ist die Trägheit eines Körpers von seinem Energieinhalt abhängig?'. In this short paper Einstein showed that a body releasing the energy E in the form of radiation will have its mass decreased by E/c2, and concluded that the mass of a body is a measure of its energy content, e.g., that all energy has mass. The next time Einstein returns to the subject is in his 1906 paper 'Das Prinzip von der Erhaltung der Schwerpunkts Bewegung und die Trägheit der Energie.'. Here Einstein concluded that one must either ascribe the inertial mass E/c2 to any form of energy E or else give up the fundamental law mechanics regarding conservation of the motion of the center of gravity. Then finally in the 1907 paper 'Über die von Relativitätsprincip geforderte Trägheit der Energie.' [the offered paper] Einstein makes the decisive step of assuming that all mass has energy. On page 382 Einstein considers the total energy of a moving mass point as the sum of its kinetic energy and its rest energy. In classical mechanics it is most convenient to set the second term to zero but in relativistic mechanics one obtains the simplest expression by setting the rest energy equal to mc2. Einstein then continues to show that this stipulation cannot lead to a contradiction in any relativistic argument. In a footnote on page 382 Einstein states for the first time the equation E=mc2 and mentions that this equation is the expression of the principle of the equivalence of mass and energy - see Volume 2 of 'The Collected Papers of Albert Einstein' pp. 428.The volume contains another paper by Einstein ""Bemerkungen zu der Notiz von Hrn.

‎First printing of Johann Albert Euler's importent paper in which he set forth the so-called ""Theorem of Johann-Albert Euler"", stating that the trajectory of a ball is a parabola followed by a straight line. The eldest son of Leonhard Euler was a prominent geometer in his own right. In 1758, Johann-Albert Euler (1734-1800) published a study of the motion of a sphere on an horizontal plane in the presence of Newtonian friction. His main result would be rediscovered independently by Gaspard Coriolis as part of his authoritative theoretical work on the topic: Théorie mathématique des effets du jeu de billard (1835). Johann Albrecht Euler, born in St. Petersburg 1732 was a Swiss-Russian astronomer and mathematician and he was the first child born to the great Swiss mathematician Leonhard Euler.‎
