This was the first step toward his atomic theory of in chemistry.‎

‎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.""

The Debye equation, involving the then recently developed quantum theory, gave agreement with observed specific heat values.

‎First appearance of these papers constituting Dirac's own theory of quantum mechanics.""Dirac wanted to establish an algebra for quantum variables, or, as he now termed them, q-numbers... He wanted his q-number algebra to be a general and purely mathematical theory that could then be applied to problem of physics. Although it soon turned out that q-number algebra was equivalent to matrix mechanics, in 1926 Dirac's theory was developed as an original alternative to both wave mechanics and matric mechanics. It was very much Dirac's own theory, and he stuck to it without paying much attention to what went on inmatrix mechanics... In the summer of 1926, Dirac published a new and very general version of q-number algebra, this timepresented as a purely mathematical theory. In this paper (offered here) he did not refer to physics at all... The work had little impact on the physics community but seems to have been appreciated by those who cultivated the mathematical aspects of quantum physics. Most of the results obtained by Dirac in his paper ""The Elimination of the Nodes in Quantum Mechanics"" had been found earlier by the German theorists using a method of matric mechanics, but Dirac was able to improve on some of the results and deduce them from his own system of quantum mechanics.""(Helge Kragh).‎

The average lifespan of a platelet is normally just 5 to 9 days. Platelets are a natural source of growth factors. They circulate in the blood of mammals and are involved in hemostasis, leading to the formation of blood clots. Platelets release thread-like fibers to form these clots.Garrison & Morton, 864.‎

‎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.

Are these two statements really separate? If the field equations were linear, they indeed would be.

VIII,1000 pp. a. 4 plates. (The entire volume offered). Einstein's paper: pp.371-384. Stamps on titlepage (Allgemeine Electricitäts-Gesellschaft a. AEG Forschungsinstitut). Internally clean.‎

‎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.

The theories laid down here is also called Euler's second theory and it is the most interesting. It was of the greatest importtence as a basis for later developments.""He applied his mathematics to astronomy, working out the nature of some perturbations, being in this respect the precursor of Lagrange and Laplace. He began to replace the geometric methods of proof used by Galileo and Newton with the algebraic, a tendency carried to its conclusion by Lagrange. In particular he worked on lunar theory, that is, on the analysis of the exact motion of the moon, the complications of which have been the despair of astronomers and mathematicians since the time of Kepler. - Eneström: 398, 399, 400 a. 401.‎

He also shows that very high speeds are necessary for good efficiency. He argues that ""by means of fixed conducting tubes, adjust the incoming velocity of the water so that the speed of efflux relative to the rotor is zero"" in this way, the theorietical efficiency will be 100% at the desired speed of operation.""""(Truesdell).Enestroem: 179.‎
