‎First appearance of Weisskopf seminal paper in which he for the very first time gave an indication that QED (Quantum electro dynamics) might be made a tractable theory.""At Pauli's suggestion [Weisskopf] computed the electron's self-energy in perturbation theory, including both electrons and positrons. In doing this calculation [Weisskopf] made a sign error, which was quickly pointed out by Wendell Furry"" when this was taken into account, the result was a self-energy that diverged logarithmically as the electron's radius a tended to zero (1934). This was an astonishing result: Classical electrodynamics was long known to produce a linear divergence, and the one-particle version of QED, already mentioned, yielded a quadratically divergent self-energy. The ""soft"" logarithmic divergence of QED with electrons and positrons was a first indication that QED might be made a tractable theory"" (Jackson, Victor Frederick Weisskopf).Later Feynman, Schwinger and Tomonago shared the 1965 Nobel Prize in Physics ""for their fundamental work in quantum electrodynamics [QED], with deep ploughing consequences for the physics of elementary particels"".‎

‎Scarce first edition. As privatdozent Hermann Weyl had given a course on Riemann's theory of functions" but instead of following his predecessors in their constant appeal to intuition for the definition and properties of Riemann surfaces, he set out to give to their theory the same kind of axiomatic and rigorous treatment that Hilbert had given to Euclidean geometry. Using Hilbert's idea of defining neighborhoods by a system of axioms, and influenced by Brouwer's clever application of Poincare's simplicial methods (which had just been published), he gave the first rigorous definition of a complex manifold of dimension 1 and a throughout treatment (without any appeal to intuition) of all the questions regarding orientation, homology, and fundamental groups of these manifolds. ""Die Idee der Riemannschen Fläche"" (1913) immediately became a classic and inspired all later developments of the theory of differential and complex manifolds.(J.Dieudonne in DSB).‎

‎First printing of Weyl's exceedingly important paper which initially did not attract much attention but ""its repercussion turned out to be remarkably strong in the long range"". (Scholz, Weyl Entering the ’New’ Quantum Mechanics Discourse , p. 14). In it Weyl put forth an analysis of the foundations of quantum mechanics.""Weyl's (1927) paper, referred to by Yang above, is entitled Quantenmechanik und Gruppentheorie (Quantum Mechanics and Group Theory). In it, Weyl provides an analysis of the foundations of quantum mechanics and he emphasizes the fundamental role Lie groups play in that theory. Weyl begins the paper by raising two questions: (1) how do I arrive at the self-adjoint operators, which represent a given quantity of a physical system whose constitution is known, and (2), what is the physical interpretation of these operators and which physical consequences can be derived from them? Weyl suggests that while the second question has been answered by von Neumann, the first question has not yet received a satisfactory answer, and Weyl proposes to provide one with the help of group theory."" (SEP)Weyl’s approach to quantization was so general that for decades to come it did not attract much attention of physicists. At the beginning it even attracted very few successor investigations inside mathematics and was not noticed in the foundation of QM discourse, which was exclusively shaped by the Hilbert and von Neumann view until the 1950s. Although the immediate reception of Weyl’s early contributions to QM until about 1927, in particular his (Weyl 1927), was very sparse, its repercussion turned out to be remarkably strong in the long range:""1. A first and immediate next step was made by Marshall Stone and John von Neumann. They both took up Weyl’s statement of a uniquely determined structure of irreducible unitary ray representations. The result of this work is (for finite n) the now famous Stone/von Neumann representation theorem.2. A second line of repercussions may be seen in that part of the work of E. Wigner and V. Bargmann, which dealt with unitary and semi-unitary ray representations. In particular Wigner’s now famous work (at the time among physicists completely neglected) on the irreducible unitary ray representations of the Poincar´e group (Wigner 1939) looks like a next step beyond Weyl’s non-relativistic quantum kinematics from 1927. 3. A third impact is clearly to be seen in George Mackeys’s work. Mackey expressedly took up Weyl’s perspective (Mackey 1949) and developed it into a broader program for the study of irreducible unitary representations of group extensions.4.Finally, Weyl quantization was taken up by mathematical physicists from the later 1960s onwards with the rise of deformation quantization (Pool 1966). Here the starting point was the idea to translate the operator product introduced by Weyl’s own quantization.The last two points lead straight into very recent developments of mathematical physics.""

‎First printing of WEYL ambitious paper in which he used the Stoney units, named after the Irish physicist George Johnstone Stoney, to unify quantum processes and gravity thereby seeking to create a ""Unified Field Theory"".

In the paper, he also describes a device with which the effect can be demonstrated experimentally.The Eötvös effect is the change in perceived gravitational force caused by the change in centrifugal acceleration resulting from eastbound or westbound velocity. When moving eastbound, the object's angular velocity is increased (in addition to the earth's rotation), and thus the centrifugal force also increases, causing a perceived reduction in gravitational force. This phenomenon had been observed in the early 20th century on research ships on which gravity was measured" they noticed that measurements of g yielded smaller values when the ship went eastward, and larger ones when they went westward. These observations are mentioned by Eötvös in a paper in which he provides the explanation of the effect.‎

‎First printing of the seminal paper that coined the term ""black hole"", giving name to a then peculiar and controversial field of study that today is considered one of the most important in modern physics and a key to understanding the universe. ""In 1968, physicist John Archibald Wheeler popularized the term ""black hole"" to describe collapsed stars that have undergone total gravitational collapse, leading to a singularity from which no light can escape... Wheeler's introduction of the term helped to demystify the concept of black holes and fostered greater public and scientific interest in the field. His pioneering research contributed to the understanding of the potential existence of black holes as significant energy sources, particularly in the centers of galaxies, and positioned him alongside other prominent figures in theoretical physics. The ongoing search for black holes, including candidates like Cygnus X-1, continues to inspire research and deepen our understanding of fundamental cosmic phenomena and the fabric of space-time."" (Zabilka). A black hole is a supermassive star that has collapsed due to exhausting its supply of nuclear fuel, and therefore gravity compresses it into a superdense sphere that absorbs anything that approaches it"" not even light can escape. John Archibald Wheeler was a pioneer in black hole research and responsible for popularizing our undersatnding of this complex phenomenon. He was a prominent physicist and mentor for Nobel prize winner, Kip S. Thorne. ""John Archibald Wheeler is a major figure in twentieth century particle and gravitational physics. Along with Schwarzschild, Oppenheimer, Roy Kerr, and Stephen W. Hawking, he stands as a pioneer in the understanding and theory of black holes. Among the most significant contributions Wheeler made was breaking down the psychological barrier that exists for scientists and public alike to believe in something that has an esoteric name. By giving the singularity a common name like black hole, Wheeler put it within reach and made acceptance of the unusual theoretical results easier. Wheeler’s timing was also impeccable. While Wheeler and many others, especially Hawking, had been studying singularities for several years immediately after the radio discovery of the pulsars and their explanation in terms of neutron stars, the total collapse into singularities was the next logical step. By giving these objects a catchy name, Wheeler was able to bring them to attention and start the massive outpouring of interest that followed. Black holes provide clues to the resolution of outstanding difficulties in cosmology. They have been proposed as explanations of the missing mass needed to bring the mass of the universe to a level where the expansion will be slow and eventually reverse into the next phase of collapse. They have been proposed as a source of the massive energy outpouring of the quasars. Further, they appear to hold significant implications for studies in the field of general relativity. Wheeler has pioneered in seeking a theory that would combine quantum physics and general relativity into a theory of quantum gravity, a first step in formulating the long-sought unified field theory in relativity studies. At the present time, relativistic equations break down when confronted with the infinite forces and gravity of a singularity. The most fruitful consequence of the naming and study of black holes has been the significant research stimulated by the effort to find black holes. While incontrovertible proof is not yet available, Cygnus X-1 and two or three other dynamical doubles where objects on the order of 10 solar masses are invisible are circumstantial candidates for status as black holes. The search to strengthen the evidence continues, and exciting results will continue to develop.""‎
