Stamp to front free end-paper and titlepage, otherwise fine and clean. Pp. 513-538; Pp. 673-702. [Entire volume: VII, (1), 790 pp.]. First printing of Heisenberg's two famous papers on "explosion showers" of cosmic rays; a subject he himself considered "the frontier of a wholly new and revolutionary physics." (DSB). "It appears to me that Heisenberg's experiences with the Fermi theory made a deep and lasting impact on him, which changed the course of his thinking. The strong increase of cross sections with energy he had found led him to surmise that physics may have to be revised at short distances. Already in his 1936 paper [the present] we find references to 'the introduction of a universal length which perhaps must be connected with a new change a principle in the formalism, just as for example the introduction of the constant c led to a modification of prerelativistic physics". Note also that 1936 was the last year Heisenberg worked on quantum electrodynamics." (Pais, Inward Bound)."While engaged in this political fight, Heisenberg vigorously pursued his search for a consistent quantum field theory. His tenacious adherence to what he believed to be the beginning of a new quantum revolution is in part attributable to his concern for the vitality of German research. In 1935 Heisenberg's research began to focus on high-energy collisions of elementary particles in cosmic rays, the highest energy phenomena then known. Examining the Fermi (weak) interaction in early 1936, Heisenberg discovered a mathematical minimum length, about the size of elementary particles, that appeared to trigger the onset of "explosion showers" of cosmic rays. The minimum length, a notion that he had earlier considered in the context of quantum eletrodynamics, marked, he belived, the boundary of quantum mechanics and the frontier of a wholly new and revolutionary physics.Heisenberg's revolutionary notions were challenged soon afterward by the alternative quantum electrodynamics of "cascade showers." generated by Bremsstrahlung and pair production. A controversy ensued, mainly between Heisenberg and several American physicists, over the existence of explosion showers and over allegiances to the two types of theories and their implications for the future course of physics. Fermi's weak-field theory soon proved inapplicable to the problem, but in 1939 Heisenberg extended his notions to Yukawa's (strong) meson theory of nuclear forces, revitalizing the controversy into the war years. A universal minimum length remained a permanent feature of Heisenberg's physics. Although explosion showers later called "multiple processes," were discovered after the war in cosmic-ray events, the invention of renormalization techniques and the experimental confirmation of quantum electrodynamics to the highest energies left Heisenberg's physics with only minority support."

London, Royal Society, 1984. Royal8vo. Full buckram, gilt lettering to spine.In: "Proceedings of the Royal Society of London", Series A, vol. 392. IV,478 pp. (Entire volume offered). Berry's paper: pp. 45-57. Clean and fine. First printing of the paper in which Berry describes his discovery of the "Berry phase", a unifying concept in quantum mechanics."In 1983, Berry made the surprising discovery that a quantum system adiabatically transported round a closed circuit in the space of external parameters acquires, besides the familiar dynamical phase, a non-integrable phase depending only on the geometry of the circuit. This Berry phase, which had been overlooked for more than half a century, provides us a very deep insight on the geometric structure of quantum mechanics and gives rise to various observable effects. The concept of the Berry phase has now become a central unifying concept in quantum mechanics, with applications in fields ranging from chemistry to condensed matter physics. In particular, the Berry phase plays an important role in modern magnetism, an allows to reach a deeper understanding of a broad range of phenomena such as the spin-orbit coupling, the Aharonov-Bohm effect, the quantum Hall effect, the anomalous Hall effect, the magnon dynamics, the tunneling of magnetization in molecular magnets, etc. Further, in the light of the Berry phase, a number of new phenomena can be predicted in ferromagnets with a textured magnetization or in semiconductors with spin-orbit coupling." (Patrick Bruno).

Chicago, The University of Chicago Press, (1939). 8vo. In the original blue printed wrappers. A very nice and clean copy - near mint. VIII, 71 pp. First printing of Carnap's seminal publication of his semantical period. Here Carnap presents a clear and detailed account of the application of logic and mathematics in empirical science and the central importance of the analytic/synthetic distinction herein.Carnap thought that the logic of science could be fruitfully applied to the problems of quantum theory as well. In particular, the final sections of Foundations of Logic and Mathematics (1939, §§24, 25) suggest that the vexed question of the "interpretation" of the wave-function can be resolved by appreciating that theories of modern mathematical physics operate with "abstract" terms which are implicitly defined, in the manner of Hilbert, in an axiomatic system (and thus require no "intuitive" or "visualizable" meaning) but which still relate to empirical phenomena (experimental measurements) indirectly. (Cambridge Companion to Carnap).These thoughts anticipate Carnap's later conception of the "partial interpretation" of theoretical terms.Rudolf Carnap (born 1891 in Ronsdorf, Germany, died 1970 in Santa Monica, California) was an immensely influential analytic philosopher, who has contributed decisively to the fields of logic, epistemology, semantics, philosophy of science, and philosophy of language. He was one of the leading figures of the Vienna Circle, and a prominent logical positivist. He studied philosophy, physics and mathematics at the universities of Berlin and Freiburg, and worked at the universities of Jena, Vienna and Prague until 1935, when he, due to the war, emigrated to the U.S., where he became an American citizen in 1941. In America he became professor of the University of Chicago.

Minor bumping to extremities. A nice, clean, uniform set. 20, 738 pp.+ (2), 739-1940 pp. + 1941-2974 pp. First publication of the first description of the world's first television satellite. Telstar I made a tremendous impact on the world by transmitting transatlantic live television. "Telstar captured the popular imagination in a way that it is hard to believe any satellite, especially a communication satellite, could do today. According to AT&T, more than half the population of the UK watched its first transatlantic transmission, a remarkable percentage given that far fewer people than today owned television sets." (Gavaghan, Something New under the Sun, p. 188)According to the US Space Objects Registry, Telstar 1 and 2 were still in orbit as of May 2010. The Telstar-satellites represent the true beginning of satellite communication.Telstar 1 was launched on July 10th 1962 and was the world's first active repeater satellite, the primary function of which was transmission of voice, black/white and colour television, fascimilie, and high- and low-speed data. The Telstar-project had five overall objectives; to demonstrate broadband transmission, test operational communication satellite reliability, obtain operational experience with ground terminals and provide space radiation measurement.Telstar 1 was a medium-altitude satellite with an elliptic orbit which was completed once every 2 hours and 37 minutes. Due to Telstar's non-geosynchronous orbit, its availability for transatlantic signals was limited to 20 minutes in each orbit that passed over the Atlantic Ocean. The Telstar 2 was almost identical with Telstar 1 but had a higher orbit to reduce exposure to the damaging effect of the radiation belt. The Chief of NASA's Communications Satellite Programs wrote in 1966: "Although not the first communications satellite, Telstar is the best known of all and is probably considered by most observers to have ushered in the era of satellite communications. This impression was a result of the tremendous impact upon the public by the first transmission of live television across the Atlantic Ocean. Telstar I was launched on July 10, 1962, and on that same day live television pictures originating in the United States were received in France." (Jaffe, pg. 107)"On the whole, Telstar made a tremendous impact in the nation by transmitting transatlantic live television, which demonstrated the possibilities for commercial satellite television and other services." (Delbert. Communication via satellite, 83 p). The Telstar-satellites were not the first launched satellites, but they were the first to demonstrate the possibilities of satellites and to present them to a broader audience. The three volumes offered contain a wide variety of articles related to the Telstar satellites from the technical design of the satellite to transmission test and evaluation to spacecraft test.Issue 1:1.

First French [and general] translation of Cantor's famous and exceedingly influential paper which contains the first proof that the set of all real numbers is uncountable; also contains a proof that the set of algebraic numbers is denumerable. "This article is Cantor's first published contribution to the theory of sets. The deep and epoch-making result of the paper is not the easy theorem alluded to in the title - the theorem that that the class of real algebraic numbers is countable - but rather the proof, in §2, that the class of real numbers is not countable [...]. And that marks the start of the theory of the transfinite. [Ewald, Pp. 839-40]."The first published writing on set theory [the present paper], contained more than the title indicated, including not only the theorem on algebraic numbers but also the one on real numbers, in Dedekind's simplified version, which differs from the present version in that today we use the "diagonal process," then unknown" (DSB)

First edition of Dewey's landmark work - one of the earliest American original contributions to psychology - in which he reformulated psychology focusing more strongly on the social environment and on the activity of mind and behavior than the psychophysics-inspired physiological psychology. This work "attempt to unite into a single system the neo-Hegelianism of Morris and the experimental psychology of Hall, or, as Dewey put it, to identify psychology with "philosophic method." During these years he moved toward a more liberal religious stance as well as toward what he would later term "instrumentalism," the view that ideas are tools for resolving and reconstructing problematic situations."

London, Printed by Taylor and Francis - Published by the Author, (1862-) 73. Folio. Papersize 54,5x37 cm. Lithographed and fully handcoloured. 2 birds seen, female and male in natural habitat, foliage. J. Gould & H.C. Richter, del. et lith. - Walter, Imp. Fine and clean. The plate is accompanied with the original textleaf. (2) pp. This is an original plate from Goulds great work "The Birds of Great Britain", issued between 1862 and 1873. The plates in this work were executed by Gould himself, and a few by J. Wolf, H.C. Richer and Hart. Together with Audubon's plates, the Gould-plates are considered the best bird-art ever produced, AND THE PLATES IN HIS "BIRDS OF GREAT BRITAIN" ARE THE PEAK OF GOULD'S ARTISTIC LIFE. In the foreword Gould stresses the difference from his "Birds of Europe" in the treatment of the illustrations, the inclusion here of the figures of the baby birds and nests, and he comments "Many of the public are quite unaware how the colouring of these large plates is accomplished; and not a few believe that they are produced by some mechanical process or by chromo-lithography. This, however is not the case; every sky with its varied tints and every feather of each bird were coloured by hand; and when it is considered that nearly two hundred and eighty thousand illustrations in the present work have been so treated, it will most likely cause some astonishment to those who give the subject a thought.". Elsewhere he remarked upon employing "almost all colourists in London." - Wood p. 364. - Nissen No. 372. - Sitwell 102. - Zimmer pp. 261-62. - Not in Jean Anker.

London, Macmillian and Co, 1927. Royal8vo. Bound in contemporary half cloth with whilte title paper-label to spine. In "Nature", vol. 119, 1927, entire volume offered. Stamp to front free end-paper and title-pages of each issue.Light wear to extremieies, otherwise fine. Pp. 558-560. [Entire volume: LIX, (1), 948, 100]. First edition of this seminal and highly influential paper on electron diffraction. Today the paper is regarded as one of the most important in the entire journal of Nature, and it led directly to Davisson receiving the Nobel Prize in physics in 1937. It advanced understanding of physics at the quantum level and led to inventions such as the electron microscope. Davisson and Germer's confirmation of the de Broglie hypothesis if today known as the Davisson-Germer experiment."Davisson's investigations on the scattering of electrons entered a new phase when, in April 1925, his taget was heavily oxidized by an accidental explosion of a liquid-air bottle. He cleaned the target by prolonged heating and then found the distribution-inangle of the secondary electrons completely changed, new showing a strong dependence on crystal direction. Prior to the accident the target had consisted of many tiny crystals, but heating converted it to several large crystals. Davisson and L. H. Germer, who had replaced Kunsman before the accident, at once began bombarding targets of single crystals. [...] When Davisson returned from England, he and Germer began a systematic research for some sort of interference phenomenon, and in January 1927 they observed electron beams resulting from diffraction by a single crystal of nickle. The results were in good agreement with de Broglie's prediction. For his confirmation of electron waves Davisson shared the Nobel Prize in physics in 1937 with G. P. Thomson." (DSB, III, 597b-598a).

Berlin, Julius Springer, 1932. 8vo. Bound in a contemporary half cloth. In "Zeitschrift für Physik". Library stamp to free front end-paper and title-page. A nice and clean copy. Pp. 318-339. [Entire volume: VII, 857 pp.]. First printing of Ruska and Knoll's seminal paper in which the first description of an electron microscope appears. This allowed researchers for the first time to view objects as small as the diameter of an atom. Not only did the discovery have profound influence on physics, it also revolutionized biological research, as it now became possible to distinguish individual molecules. Ruska received the Nobel Prize in physics in 1986 for his discovery regarding the electron microscope.In 1933 the theoretical description presented in the present paper led Ruska to build a two-stage electron microscope with a resolution exceeding that of the optical microscope. The technique behind is largely built upon de Broglie's revolutionary theory regarding the wavelength of electrons. The volume contains many important contributions to 20th century physics, among others: Heisenberg, W. Über den Bau der Atomkerne. II. Pp. 156-64: This is the second paper in a series of three which presents Heisenberg's neutron-proton model. Shortly after Chadwick discoverd the neutron in 1932, Heisenberg developed a theory suggesting that atomic nuclei are composed of protons and neutrons, this introduced the concept of the nuclear exchange force and isotopic spin.
