‎First printing of the complete and accurate Debye-Waller factor. Peter Debye introduced the concept in 1913 but it was not untill Waller in 1923 with the present publication gave the complete fully usefull Debye-Waller factor.The Debye-Waller factor is the ratio of the coherent scattering or absorption cross section of a photon or electron by particles bound in a complex system to the value for the same process on an analgous free particle. It is often interpreted also as the probability of the coherent process, normalized to unity, with the difference between unity and the Debye Waller factor interpreted as the probability of incoherent processes.‎

‎First printing of Wallner's important paper on microscopic lines - Wallner Lines - in various materials. Wallner lines are microscopic fractures that propagate on a rigid surface. Using the Wallner lines, it is possible to determine the speed at which a surface is cracked. The method works for example on glass, epoxy, tungsten and carbon-filled rubber. The measurement of Wallner lines are a standard method of modern forensic science.‎

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"".‎

‎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.‎

‎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"". The paper appears to have inspired Dirac's fascination with the large number hypothesis.Also contain in this volume is the first appearance of EÖTVÖS' important paper in which he explains the eastward deflection of falling objects. 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.‎

‎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.""

‎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.""
