‎First printing of three landmark papers, all of seminal importance in history of physics: Feynman's undergraduate thesis at MIT, the intricacies of the fission process, the groundwork for atomic and hydrogen bombs and the forgotten birth of black holes: The first theoretical description of a black hole, the production of a singularity when a sufficiently large neutron star collapses.First printing of ""FORCES IN MOLECULES"" - know known as Feynman-Hellmann theorem - is Feynman's undergraduate thesis at MIT, published when he was just twenty-one, which helped to establish his name in the world of physics. ""This work treated the problem of molecular forces from a thoroughly quantum-mechanical point of view, arriving at a simple means of calculating the energy of a molecular system that continues to guide quantum chemists."" (DSB). ""As Feynman conceived the structure of molecules, forces were the natural ingredients. He saw springlike bonds with varying stiffness, atoms attracting and repelling one another. The usual energy-accounting methods seemed secondhand and euphemistic: [He demonstrated that] the force on an atom's nucleus is no more or less than the electrical force from the surrounding field of charged electrons-the electrostatic force. Once the distribution of charge has been calculated quantum mechanically, then from that point forward quantum mechanics disappears from the picture. The problem becomes classical"" the nuclei can be treated as static points of mass and charge. Feynman's approach applies to all chemical bonds"" (Gleick, The Life and Science of Richard Feynman, P. 54).Oppenheimer and Snyder's ""ON CONTINUED GRAVITATIONAL CONTRACTION"" constitutes the very first theoretical prediction of a singularity when a sufficiently large neutron star collapses. This phenomenon was later to be coined as a black hole. ""Had J. Robert Oppenheimer not led the US effort to build the atomic bomb, he might still have been remembered for figuring out how a black hole could form."" (American Physical Society). Many historians of physics describe this paper as the forgotten birth of black holes. ""Oppenheimer and his graduate student George Volkoff presented the first analysis of the formation of a neutron star in a 1939 Physical Review paper titled, ""On Massive Neutron Stars"". Oppenheimer wondered what would happen to a very massive neutron star. The Schwartzschild analysis of General Relativity has a theoretical limit, called the ""Schwartzschild limit"", when the ratio of mass-to-radius of a star is 236,000 times greater than the ratio for our sun. When this limit is exceeded, the Schwartzschild analysis does not yield a solution. Oppenheimer believed that a neutron star could have sufficient mass to exceed this limit. What would happen to it? Oppenheimer and his graduate student Hartland Snyder applied General Relativity theory to a star with sufficient mass and density to exceed the Schwartzschild limit. The Schwartzschild analysis assumed that the size of the star stays constant with time. Oppenheimer and Snyder found that they could achieve a real solution from General Relativity when the Schwartzschild limit is exceeded by assuming that the diameter of the star decreases with time. They presented their analysis in a 1939 Physical Review paper, titled, ""On Continual Gravitational Contraction,"" which concluded with: ""When all thermonuclear sources of energy are exhausted, a sufficiently heavy star will collapse. Unless fission due to rotation, the radiation of mass, or the blowing off of mass by radiation, reduce the star's mass to the order of that of the sun, this contraction will continue indefinitely."" This analysis concluded that when the Schwartzschild limit is exceeded, the star must collapse indefinitely until it reaches a singularity having an infinite density of matter"" (Bjornson, Singularity Predictions of General Relativity, P. 4).The Chandrasekhar / Eddington controvery in the mid 30ies did discuss the fate of neutron stars but the first thoroughly theoretical desciption was first published here. ""THE MECHANISM OF NUCLEAR FISSION"" is the first fully worked out theory of nuclear fission, which laid the groundwork for atomic and hydrogen bombs.""Wheeler's technical mastery of physics is best seen in the classic paper of Bohr and Wheeler. Bohr and Wheeler wrote the paper in Princeton, where Bohr was visiting in the spring of 1939, a few months after the discovery of fission. The paper is a masterpiece of clear thinking and lucid writing. It reveals, at the center of the mystery of fission, a tiny world where everything can be calculated and everything understood. The tiny world is a nucleus of uranium 236, formed when a neutron is freshly captured by a nucleus of uranium 235. The uranium 236 nucleus sits precisely on the border between classical and quantum physics. Seen from the classical point of view, it is a liquid drop composed of a positively charged fluid. The electrostatic force that is trying to split it apart is balanced by the nuclear surface tension that is holding it together. The energy supplied by the captured neutron causes the drop to oscillate in various normal modes that can be calculated classically. Seen from the quantum point of view, the nucleus is a superposition of a variety of quantum states leading to different final outcomes. The final outcome may be a uranium 235 nucleus with a re-emitted neutron, or a uranium 236 nucleus with an emitted gamma-ray, or a pair of fission-fragment nuclei with one or more free neutrons. Bohr and Wheeler calculate the cross-section for fission of uranium 235 by a slow neutron and get the right answer within a factor of two. Their calculation is a marvelous demonstration of the power of classical mechanics and quantum mechanics working together. By studying this process in detail, they show how the complementary views provided by classical and quantum pictures are both essential to the understanding of nature. Without the combined power of classical and quantum concepts, the intricacies of the fission process could never have been understood. Bohr's notion of complementarity is triumphantly vindicated"" (John Archibald Wheeler, Proceedings of the American Philosophical Society 154 (2010)).‎

‎First printing of Finkelstein's landmark paper in which he identified the Schwarzschild surface as an event horizon, ""a perfect unidirectional membrane: causal influences can cross it in only one direction"". This did not strictly contradict Oppenheimer's results, but extended them to include the point of view of infalling observers. Finkelstein's solution extended the Schwarzschild solution for the future of observers falling into a black hole. This paper influenced Penrose and Landau and essentially triggered the black-hole research.""Many prominent doubting physicists were reluctant to accept the concept of a black hole, in large measurement because of the anomaly that the implosion of a star cannot be observed. Yet a particle inexorably falls into the center at r = 0 just as time marches on - because in general relativity time and space exchange roles inside a black hole (which has the making of another paradox). One solution, or at least reconciliation, of the observational black hole paradox was achieved only in the last decades. David Finkelstein (in the present paper) ascertained a new reference frame of framework for Schwarzschild space-time. Finkelstein's reference frame simultaneously covered all regions of space-time from the imploding star to distant reaches of space. This all-embracing reference frame is now called the Eddington-Finkelstein frame"" (Kreitler, Trends in Black Hole research, P. 6). ‎

‎On the Conversion of Electric Oscillations into Continous Currents by means of a Vacuum Valve. (+) An Instrument for the Measurement of the Lenght of Long Electric Waves, and also Small Inductances and Capacities. - [THE ""FLEMING-VALVE""]‎

‎London, Harrison and Sons, 1905. 8vo. In the original printed wrappers. In ""Proceedings of the Royal Society of London"", vol. 74, No. 505. With new paper back-strip (presumably after having been extracted from a binding). Ex-libris (""Alan. A. C. Swinton"") pasted on to verso of title-page. Internally fine and clean. Pp. 476-487"" pp. 488-498. [Entire volume: Pp. (2), 447-518].‎

‎First printing of these two seminal articles, in which the basic principle of the modern wireless valve, also called the ""Fleming Valve"", is introduced for the first time, making radio-telephony and broadcasting possible. ""The immense superiority of the Fleming thermionic valve to all previous detectors of wireless waves caused it to be widely used as an efficient and reliable detector."" (PMM). When Lee DeForest perfected the ""grid"" in 1907, Fleming's wireless signals could be amplified to the degree necessary to make radio-telephony and broadcasting possible. The Edison effect was first described in a paper by William Henry Preece, who was shown an experiment by Edison ""On a peculier of Glow-Lamps when raised to high Incasdence"", 1885. This effect was known as the ""Edison effect"", and in 1890 Fleming, an electrical engineer who had worked with Edison Company in London and was now professor at University College, began a careful study of this phenomenon in carbon filament lamps. In 1904 he was able to demonstrate that this occurred not only with electric waves but also with wireless waves. He thus introduced the basic principle of the modern wireless valve, which permits only unilateral conductivity. (see PMM No. 396).
