(Entire volume offered). (12),452 pp. and 4 folded engraved plates. Internally clean and fine. Small stamps on verso of titlepage. Laplace's papers: pp. 1-114, pp. 141-182, pp. 273-293, pp. 293-338 a. pp. 373-394. First German edition of Laplace's groundbreeking papers on the "Short-range Forces" i.e. capillary action, cohesion of solids, chemical reactions etc., where Laplace makes a major contribution to the mathematization of the subject. The papers are his first contributions to mathematical physics, and appeared as supplements to Book X of the fourth volume of his "Traité de mécanique céleste"."The importence, for Laplace's theory, of the shortrange character of the molecular forces cannot be overstressed. Small terms involving the square of the distance were repeatedly ignored, and it is no coincidence that in his concluding remarks to the second supplement Laplace reiterated his belief in the idntity of the forces at work in optical refraction, capillary action, and chemical reactions. In accordance with his belief that capillarity is a consequence of intermolecular action at a distance (albeit a very small distance), he tried to determine the relativemagnitude of the attractive force between the particles composing the liquid (F1) and the force between the particles of liquid and those of the tube (F2).... experiments, performed at Laplace's request, by Gay-Lussac, Haüy, and Jean-Lois Trémary...gave the theory added plausibility, as Laplace himself was always ready to observe; and they certainly helped it to survive the criticism of Laplace's only contemporary rival in the treatment of capillarity, Thomas Young."(DSB XV, Suppl. I, pp. 358 ff.).

Berlin, Julius Springer, 1927. 8vo. In contemporary half cloth with gilt lettering to spine. In "Zeitschrift für Fhysik", vol. 46. Entire volume offered. Library stamp to title page. Pp. 1-46. [Entire volume: VII, (1), 902 pp.]. 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."

Leipzig, B. G. Teubner, 1909. 8vo. Bound in contemporary half calf with gilt lettering to spine. In "Mathematische Annalen", 67 band. 1909. Bookplates to pasted down front free end-paper and library stamp to verso of title page. Top half of spine is detached. Bookblock, however, still firmly attached. Fine and clean. Pp. 281-300. [Entire volume: IV, 575 pp.]. First printing of a groundbreaking work in Number Theory. Edward Waring (1734-98) stated, in his "Meditationes Algebraicae" (1770), the theorem known now as "Waring's Theorem", that every integer is either a cube or the sum of at most nine cubes; also every integer is either a fourth power of the sum of at most 19 fourth powers. He conjectured also that every positive integer can be expressed as the sum of at most r kth powers, the r depending on k. These theoremes were not proven by him, but by David Hilbert in the paper offered.Hilbert proves that for every integer n, there exists an integer m such that every integer is the sum of m nth powers. This expands upon the hypotheis of Edward Waring that each positive integer is a sum of 9 cubes (n=3, m=9) and of 19 fourth powers (n= 4, m=19).This issue also contains F. Hausdorff's "Zur Hilbertschen Lösung des Waringschen Problems", pp. 301-305.(Se Kline p. 609).

Clean and fine First edition of this importent paper where Fraunhofer analyzed diffration phenomena and interpretet them in terms of a wave theory of light, leading him to formulate the GRATING EQUATION. - "In the paper in 1823, Fraunhofer revealed his continued invstigation of diffraction gratings. Using a diamont point, he could rule up to 3,200 lines per Parish inch. He continued his study of the effect of oblique reays, developed formulations based on the wave conception, and calculated a revised set of wavelenghts for the major spectral lines. Thus, his earlier observations of the dark lines in the solar spectrum enabled him to make the highly precise measurements of dispersions; then his ude of the wave theory of light allowed him to derive, with suitable simplifications, the general formulation of the grating equation still in use today."

(Paris, Victor Masson, 1849). Without wrappers. In: "Annales de Chimie et de Physique", Troisieme Series - Tome 26. Cahier 3-4. Pp. 299-528 a. 2 folded engraved plates, showing apparatus used.(Entire issues offered). The joint paper takes up both issues. With half-title to tome 26. First appearance of this classic paper, which contains extensive comparative studies of respiration and calorimetry. They refined Lavoisier's experiments on measuring the oxygen uptake and carbon dioxide production of animals and calculated the first good ratios of what came to be called the "RESPIRATORY QUOTIENT". It was the use of the apparatus and methods developed here, that enabled scientists the world over to gain some understanding of utilization of energy by many different animals.The inspiration for the space age scientific novel by JULES VERNE "De la Terre a la Lune" (1865) was based on the methods described by Regnault and Reiset in this paper to provide oxygen and remove carbon dioxide produced by men, dogs and chickens in the "projectile". The paper is cited several times in this famous novel.The species study in the Regnault and Reiset collaboration included warm-blooded animals, such as dogs, cats, and rabbits as well as hibernating and non-hibernating marmots. Cold-blooded animals , such as frogs, salamanders, reptiles and lizards were also described...In over 100 experiments their assays included the effects of temperature, season, diet, level of nutrition, compositionof air, sex, hibernation, age, body weights and other variables onrespiratory exchange and nitrogen exhalation or absorption (Based on W. Flatt & W. Payne).Garrison & Morton: 932.

Babbage's paper: pp. 557-560. Some faint, mostly marginal brownspots. First printing of this importent paper being babbage's report on the Scheutz differnce calculator, explaining its functions by way of his own notations."Babbage's report on the differnce engine built by the Swedish printer Georg Scheuts (1785-1873) and his son Edvard (1821-81), based on Babbage's own designs.... In 1854 the Scheutzes took their engine no. 2 to England in the hopes of marketing it. There they were introduced to Babbage, who received them with great friendliness and showed a lively interest in their work. Babbage devoted two whole days to investigating Scheutz' engine for which he had much praise, especially for the way they had succeeded in building it with the funds at their disposals.... As part of his effort to promote the Scheutz Engine, Babbage gave a talk on it before the Academie des Sciences, illustrated with drawings by his son henry, in which Babbage's system of mechanical notation was used to describe the machines construction and functions. This talk was published (the paper offered) without illustrations in the Academie 'Comptes rendus'. ((Hook & Norman "Origins of Cyberspace", No. 73).

Pennsylvania, The American Institute of Physics for the Acoustical Society of America, 1959. 4to. In the original yellow printed wrappers. In "The Journal of the Acoustical Society of America", Vol. 31, No. 9, September, 1959. Pp. 1253-56. [Entire volume: xii, 1161-1296 pp]. A fine and clean copy. First edition of the important paper in which Ehmer described a complete set of auditory curves, which are regarded as the earliest contribution to the later development of digital audio files, MP3, today used in all iPods and digital music players. The MP3 algorithm takes advantage of a perceptual limitation of human hearing called auditory masking, as introduced in the present paper.Moving Picture Experts Group (hence the names: MPEG-1 or MPEG-2 Audio Layer 3 (or III), more commenly referred to as MP3), began development of the digital audio system "1 Audio Layer 3" in 1959, when Richard Ehmer first came up with the idea of auditory masking. It was, however, not until 1989, when Oscar Borello at the University of Buenos Aires, developed the first fully working device to play digital audio files, that it became a reality. The first personal MP3 player was released in September 1995 and when Nullsoft's audio player Winamp came in 1997 its popularity increased tenfold. The MP3-file is probably the most disputed and infamous - in the eyes of large record labels - computer related development ever released. The MP3 made it easy to exchange music, legal as well as illegal; major record companies started arguing that free sharing of music caused fewer sales, and they initiated lawsuits, the most famous being Napster.To this day the MP3-file is probably the most used and exchanged file in the entire history of the electronic computer.

Leipzig, B.G. Teubner, 1904. With orig. printed wrappers (no backstrip) to 4. Heft, 59. Bd. of "Mathematische Annalen". The issue: pp. 449-572. Zermelo's paper: pp. 514-516. First appearence of this fundamental paper in metamathematics and mathematical logic. By this paper Zermelo contributed decisively to the development of set-theory. Zermelo took up the problem, left over by Cantor, of what to do about the comparison of sets that are not well-ordered. "In 1904 (the paper offered) he proved....that every set can be well-ordered. To make the proof he had to use what is now known as the axiom of choice (Zermelo's axiom), which states that given any collection of nonempty, disjoined sets, it is possible to choose one member from each set and so make up a new set. The axiom of choce, the well-ordering theorem, and the fact that any two sets may be compared as to size, are equivalent principles."(Morris Kline). A controversy arose around "The axiom of Choice", from Bertrand Russell, Tarski, Frege, Hilbert, Brouwer and others, mainly, and of course importent, over how to interpret the words "choose" and "exists".

Both works in "Annales de Chimie et de Physique", 5me Series - Tome IV. 572 pp. (The entire volume offered). Berthelot's works: pp. 5-131 a. 141-214 + pp. 445-537. Internally clean and fine. First appearance of this collection of Berthelot's famous memoirs on thermochemistry to which he turned his attention in 1865. In these lectures he introduced the concepts of 'exothermix' and 'endothermic'. He also intorduce his famous 3 principles - equivalence between internal and heat changes in chemical reactions, heat evolved or absorbed in a chemical change depends onlyon the initial and final states of the reactans and products, provided no external work is done, and "law of maximum work" which says that "every chemical change accomplished without the intervention of energy from outside tends towards the production of a body or system of bodies which produce the most heat". The principles of Thermochemistry given here Berthelot considered himself fundamental."In the 1860s Berthelot was done with synthesis and turned to thermochemistry, the study of the heat of chemical reactions. In some of his work he had unknowingly been anticipated by Hess, but he went much further. He devised a calorimeter within which he could measure the heat of chemical reactions and ran hundreds of determinations. This work along with that being conducted by Thomson threw the science of thermochemistry into high gear."(Asimov).
