‎These seminal papers constitutes the description of the first realization of artificial radioactivity produced by neutron bombardment, and it is the first demonstration of neutron-induced radioactivity. These highlights and his many other results have left their imprint on the most diverse parts of physics. Fermi was awarded the Nobel prize in 1938 for these discoveries.""Acting on this idea, (Fermi reasoned that neutrons should be more effective than alpha particles in producing radioactive elements because they are not repelled by the nuclear charge and thus have a much greater probability of entering the target nuclei) Fermi bombarded several elements of increasing atomic numbers with neutrons. He hoped to find an artificial radioactivity produced by the neutrons. His first success was with fluorine. The neutron source was a small ampul containing beryllium metal and radon gas. The detecting apparatus consisted of rather primitive Geiger-Müller counters. Immediately thereafter Fermi, with the help of Amaldi, D’Agostino, Rasetti, and Segrè, carried out a systematic investigation of the behavior of elements throughout the periodic table. In most cases they performed chemical analysis to identify the chemical element that was the carrier of the activity. In the first survey, out of sixty-three elements investigated, thirty-seven showed an easily detectable activity. The nuclear reactions of (n, a), (n, p), and (n, ?) were then identified, and all available elements, including uranium and thorium, were irradiated. In uranium and thorium the investigators found several forms of activity after bombardment but did not recognize fission. Fermi and his collaborators, having proved that no radioactive isotopes were formed between lead and uranium, put forward the natural hypothesis that the activity was due to transuranic elements. These studies, which were continued by Otto Hahn, Lise Meitner, Irène Joliot Curie, Frédéric Joliot, and Savitch, culminated in 1938 in the discovery of fission by Hahn and Fritz Strassmann.""(DSB).""The present papers are a summary of these letters (the letters from the team communicated almost weakly to ""Ricerca Scientifica"") for the English speaking readers. ""When we (Fermi and Segre) went to Cambridge, we discussed with him (rutherford), in great detail, our work. The work which had been accomplished up to that date by our group is summarized in a paper which was presented by Lord Rutherford to the Royal Society (Paper No. 98). The manuscript of this paper had been prepared in Rome and delivered to him in Cambridge. he read it immediately with great attention, made several corrections to improve our English, and turned it over to the Royal Society. I asked him whether it would be possible to obtain a speedy publication and he immediately answered ""What did you think I was President of the Royal Society for ?"" (Collected Papers of Enrico Fermi, Vol. I, p. 641).Volume 149 contains the importent joint paper on SUPERCONDUCTIVITY by the brothers FRITZ And H. LONDON ""The Electromagnetic Equations of the Superconductor"", pp. 71-88.""In 1933 shortly before Heinz London joined his brother at Oxford, W. Meissner and R. Ochsenfeld made a startling discovery. It was well known that currents in superconductors flow in such a way as to shield points inside the material from changes in the external magnetic field. This indeed is an obvious property of any resistance less medium, fully discussed by Maxwell in 1873 long before the discovery of superconductivity. But a superconductor does more. Whereas a zero resistance medium only counteracts changes in the field, it actually tends to expel the field present in its interior before cooling.... The London quickly saw its implications and in 1935 published a joint paper on the electrodynamics of superconductors, in which they replaced (paper by Deaver and Fairbanks) by a new phenomenological equation connecting the current with the magnetic rather than the electric field...

‎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"" constitute 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). The paper has by several physics historians been described 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 appearance of Feyman's landmark Quantum Electrodynamics (QED) illustrated but his famous Feynman-Diagrams which ""revolutionized nearly every aspect of theoretical physics"" (Kaiser, Physics and Feynman's Diagrams). The whole field of quantum electrodynamics advanced greatly because of this graphical formalism, which allowed researchers to communicate in an effective manner. Feynman, Schwinger and Tomonago shared the 1965 Nobel Prize in Physics ""for their fundamental work in quantum electrodynamics, with deep ploughing consequences for the physics of elementary particles"".""At Cornell, Feynman perfected his approach to quantum theory, melding several of his prewar insights with the more pragmatic, numbers-driven approach he had honed during the war. One of his first tasks was to publish a long article, based on his dissertation, that presented a brand-new approach to quantum mechanics. Published in 1948 under the title, 'Space-Time Approach to Non-relativistic Quantum Mechanics'"" in the journal Reviews of Modern Physics, his lengthy article focused on the 'Lagrangian' function for a particle, a particular combination of kinetic and potential energy familiar from classical mechanics. The probability that a quantum object would travel from one location, x1, at a time t1, to some other location, x2, at a later time t2, Feynman showed, could be calculated by summing over-that is, integrating-all of the possible paths through space and time that connected these two end points. The contribution of each path to the total would be weighted by its classical Lagrangian function evaluated along that path"" hence, the technique became known as path integrals. The main difference from the standard formalism lay not in outcomes, but in conceptual approach. Werner Heisenberg and Niels Bohr had argued vehemently during the 1920s that quantum mechanics spelled the end for any type of visualization of the atomic domain. Feynman countered with an intuitive approach, built around picturing the paths of particles through space and time. His greatest success [with his Feynman-diagrams] came on the heels of this path-integral approach"" (DSB).""Feynman's two papers on QED [the two present papers] were completed in April and May 1949. In the first one, 'The Theory of Positrons,' he carefully explains the meaning of his diagrams beginning with their application to the Schrödinger equation. Application to the Dirac equation yields an interpretation of the positron in which Dirac's original hole theory is no longer needed. The second paper, 'Space-Time Approach to Quantum Electrodynamics,' contains the Feynman rules and explains their usage. By these rules, computations for specific problems are simplified so much that Schwinger, much later, said: ""Like the silicon chip of more recent years, the Feynman diagram was bringing computation to the masses"""" (Brandt, Harvest of a Century).Dean Everett Wooldridge (1913 - 2006) was a prominent engineer in the aerospace industry.‎

‎First edition of Fermi's seminal and exceedingly important paper on beta-decay. In one stroke, Fermi had solved the major problem of beta decay: How do electrons come out of the nucleus if there are non to begin with? In the paper he coined the term neutrino and his groundbreaking work awarded him the Nobel Prize in physics in 1938.How pioneering and daring Fermi's theory was became clear when he first submitted his paper to the prestigious journal Nature. The journal's editor turned it down because ""it contained speculations which were too remote from reality"", consequently it became published in Zeitschrift für Physik. Eventually six years later, in 1939, Nature published Fermi's paper.In late 1933 Fermi wrote his famous article offering an elegant solution to a well know problem: Fermi proposed an entire new force of nature, the weak force. ""This new force, together with gravity, electromagnetism, and the strong interaction which binds the particles of the nucleus, constitutes the family of forces presently known in physics. The should account for the whole universe. Weak interactions [forces] occur between all particles and are thus unlike electromagnetism or strong interactions, which are restricted to certain particles. The first manifestation of the weak interaction to be treated in detail was the beta decay."" (DSB, IV, p. 579b).The ""canonical formalism of Heisenberg and Pauli gave rise, in the thirties and forties, to many applications of which the most important may be mentioned here: 1934 Enrico Fermi gave the formal explanation of beta-radioactivity of atomic nuclei by making use of the hypothesis formulated by Pauli in 1930 which postulated the existence."" (Enz, Charles. Of Matter And Spirit, 2009, p. 167).Pauli had named his proposed light particle a neutron. James Chadwick had named his much more massive nuclear particle a neutron as well which left the two particles with the same name. Fermi therefore, to solve the confusion, coined the term neutrino (Italian diminutive of neutron). Fermi is widely regarded as one of the leading scientists of the 20th century, Along with Oppenheimer he is frequently referred to as ""the father of the atomic bomb"".‎

In this sense atomic physics was showing signs of exhaustion, and one could expect the next really important advances to be in the study of the nucleus. Realizing this, Fermi decided to switch to nuclear physics. He initially investigated the theory of the hyperfine structure of the spectral lines and the nuclear magnetic momenta (FP no. 57), a suitable subject for making the transition from atomic to nuclear physics.""‎
