‎Die specifischen Wärmen der Elemente Kohlenstoff, Bor und Silicium. (2 Parts).‎

‎Leipzig, Johann Ambrosius Barth, 1875. Contemp. hcalf. Spine gilt. raised bands. Spine slightly rubbed. In ""Annalen der Physik und Chemie. Hrsg. von J.C. Poggendorff"", Bd. 154. X,644 pp. and 5 folded engraved plates. (Entire volume offered). Weber's paper: pp. 367-423 a. pp. 553-582.‎


‎First appearance of this importent paper in which Weber was able to explain why the Law of Dulon & Petit, based on the specific heat of only thirteen elements, was only approximately true. ""An explanation of this anomalous behaviour is to be found in the fact that, as shown by the physicist Heinrich Friedrich Weber, and confirmed by many workers in more recent times, the atomic heat increases at different rates with rise of temperature.... A theoretical basis for this law was obtained in more recent times by P. Debye.""(Findley ""A Hundred Years of Chemistry"", p. 77-78).""The three curious exceptions (C, B, Si) to the Dulong-Petit Law which were until now a cause for despair have been eliminated: the Dulong-Petit law for the specific heats of solid elements has become an exceptional rigorous law...""(Weber).On Albert Einstein and Weber's specific heat, see Pais: ""Subtle is the Lord"", pp. 389 ff.‎

‎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"".‎

‎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. ‎

‎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).‎
