‎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"".‎

Il a cherché en particulier à savoir pourquoi et comment une substance comme le fer peut s'aimanter de façon forte et permanente alors que la plupart des autres matériaux restent inertes ou s'aimantent faiblement et transitoirement quand ils sont mis en présence d'un champ magnétique. Pierre Weiss a fait d'importantes découvertes théoriques qui l'ont conduit à inventer des électroaimants très puissants. Il a enseigné à Rennes, à Lyon, à l'École polytechnique fédérale de Zurich dont il avait été élève, et enfin à Strasbourg. Dans ces Universités, il a fondé des laboratoires renommés par leurs recherches et par les chercheurs qui s'y sont formés. - Pierre Weiss s'intéresse aux propriétés magnétiques de la matière en présence d'un champ magnétique extérieur. Ses recherches s'inscrivent dans une longue série de travaux initiée par Michael Faraday en 1845 et poursuivie par André-Marie Ampère, James Clerk Maxwell, James Ewing, Pierre Curie et Paul Langevin. Ces travaux se développent dans le cadre de la physique classique complétée par la thermodynamique statistique de Ludwig Boltzmann. Pierre Weiss prend le relais des travaux de Curie et Langevin. Il jette les fondements de la théorie du ferromagnétisme qui sera, par la suite, réinterprétée par Werner Heisenberg et Niels Bohr en 1929 dans le cadre de la mécanique quantique. Et c'est Louis Néel, un élève de Pierre Weiss, qui poursuit ces recherches pour lesquelles il obtient le Prix Nobel de Physique en 1970.

‎First printing of Weizsäcker's exceedingly important paper containing the first appearance of Bethe-Weizsäcker formula, or Semi-Empirical Mass Formula (SEMF), a theoretical formula relating the curve of nuclear binding energy, nuclear masses, and certain other nuclear properties.In nuclear physics, the semi-empirical mass formula (SEMF) (sometimes also called Weizsäcker's formula, the Bethe-Weizsäcker formula, or the Bethe-Weizsäcker mass formula to distinguish it from the Bethe-Weizsäcker process) is used to approximate the mass and various other properties of an atomic nucleus. As the name suggests, it is based partly on theory and partly on empirical measurements. The theory is based on the liquid drop model proposed by George Gamow, which can account for most of the terms in the formula and gives rough estimates for the values of the coefficients. Although refinements have been made to the coefficients over the years, the structure of the formula remains the same today.The present volume also contain conttributions by Wener Heisenberg: Die Struktur der leichten Atomkerne. ‎

‎---- PREMIERE EDITION FRANCAIS ---- "H.

‎Scarce first edition. ""In his 1818 monograph ""Ds Kontinuum"" Hermann Weyl initiated a program for the arithmetical foundations of mathematics. In the years following, this was overshadowed by the foundational scemes of Hilbert's nitary consistency program and Brouwer's intuitionistic redevelopment of mathematics. In fact, nor long after his own venture, Weyl became a convert to Brouwerian intuitionism and critized his old teachers program. Over the years, though, he became more and more pessimistic about the practical possibilities of reworking mathematics along intuitionistic lines, and pointed to the value of his own early foundational works. Weyl's work ""Das Kontinuum"" has come to be recognized for its importence as the opening chapter in the actual development of predicative mathematics, whose extent has been plumbed both mathematically and logically since the 1960'ties.""

‎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.""
