First edition of Bardeen' paper on hole concentration and germanium point contacts. Bardeen is known as the inventor of the transistor, for which he, together with Shockley, was awarded the Nobel Prize in Physics in 1956. Bardeen is the only person to have been awrded the Nobel Prize in Physics twice, first in 1956 and again in 1972 for his part in the development of the theory of superconductivity (BCS-theory) and thus became the only person, until this day, to receive the Nobel Prize more than once in the same field.

Wicksell contributed to a number of different economic disciplines, including his groundbreaking work in monetary theory. "The standard view of the quantity theory before Wicksell was that increases in the money supply have a direct effect on prices - more money chasing the same amount of goods. Wicksell focused on the indirect effect. In elaborating this effect, Wicksell distinguished between the real rate of return on new capital (Wicksell called this the 'natural rate of interest') and the actual market rate of interest. He argued that if the banks reduced the rate of interest below the real rate of return on capital, the amount of loan capital demanded would increase and the amount of saving supplied would fall. Investment, which equaled saving before the interest rate fell, would exceed saving at the lower rate. The increase in investment would increase overall spending, thus driving up prices. This cumulative process of inflation would stop only when the banks’ reserves had fallen to their legal or desired limit, whichever was higher.In laying out this theory, Wicksell began the conversion of the old quantity theory into a full-blown theory of prices. The Stockholm school, of which Wicksell was the father figure, ran with this insight and developed its own version of macroeconomics. In some ways this version resembled later Keynesian economics. Among the young Swedish economists who learned from Wicksell were Bertil Ohlin, Gunnar Myrdal, and Dag Hammarskjöld, later secretary general of the United Nations."

Lancaster, American Institute of Physics, 1951. Lex8vo. Volume 84, December 15, No. 6, 1951 of "The Physical Review", Second Series. Entire volume offered in the original printed blue wrappers. Previous owner's stamp to front wrapper. Minor wear to extremities and a bit of discolouring to spine and extremities. Front wrapper with light tie-markings after having been bundled and tied. Fine and clean. Pp. 1232-1242. [Entire issue: Pp. 1079-1286, iii-x]. First publication of the influential and groundbreaking description (the detailed description including the derivation) of the Bethe-Salpeter equation. Due to its generality, it has been used in nearly all branches of theoretical physics and has been presented in many different forms. In general, the theory describes the bound states of a two-body quantum field theoretical system in a relativistically covariant formalism. In Early 1951, Bethe and Salpeter published a paper in which they introduced the concept of the Bethe-Salpeter equation but had not made the final calculations and derivations. This paper presents the theory including the derivation and is therefore known as the first documented publication of the theory.

(Berlin, Julius Springer, 1924). 8vo. Bound in contemporary half cloth. In: "Zeitschrift für Physik", 21-22 band, 1924. Find and clean. Pp. 73-110. [Offered volume: Pp. 382, V, 416.] First printing of Lanczos exceelingly important paper in which he discovered an exact solution of the Einstein field equation which represents a cylindrically symmetric rigidly rotating configuration of dust particles. This was later rediscovered by Willem Jacob van Stockum and is known today as the van Stockum dust. It is one of the simplest known exact solutions in general relativity and regarded as an important example, in part because it exhibits closed timelike curves. Lanczos served as assistant to Albert Einstein during the period of 1928-29.

Berlin, Weltkreis-Verlag, 1928. 8vo. In the original printed wrappers. Wear to extremities, loss to top and bottom of spine and a waterstain to the right part of front wrapper. Internally with light pencilmarks throughout. 46 pp. First printing of Carnap's publication in which asserted that many philosophical questions were meaningless, the way they were posed amounted to abuse of language. An operational implication of this opinion was taken to be the elimination of metaphysics from responsible human discourse. This is the statement for which Carnap was best known for many years.The publication also introduces for the first time his universal "meaning criterium". He indicates that the elimination of metaphysics serves philosophy, not science. All in the Vienna Circle followed Carnap's judgement in Pseudoproblems of Philosophy and Schlick's contention in his response to Planck's renewal of anti-Machian polemics that questions like that of the reality of the external world were not well-formed ones but only constituted pseudo-questions. (Stanford Encyclopedia of Philosophy). Carnap himself said about the publication: "The pamphlet Scheinprobleme in der Philosophie… was first written in the Spring of 1927, at the end of my first year in Vienna. It shows, therefore, a stronger influence of the Vienna discussions and Wittgenstein's book [Tractatus]. [the] condemnation [in Scheinprobleme] of all theses about metaphysical reality, which I sharply distinguish from empirical reality, is more radical than that in Aufbau, where such theses are only excluded from the domain of science. My more radical outlook was influenced by Wittgenstein's view that metaphysical statements, while in principle unverifiable, are therefore senseless. This view was accepted by the majority of the members of the Vienna Circle and other empiricists." (Nieli. Wittgenstein: From mysticism to ordinary language. P. 63.).

Berlin, G. Reimer, 1827. 4to. As extracted from "Journal für die reine und angewandte Mathematik, 2. Band, 1827"., without backstrip. Fine and clean. [Gudermann:] Pp. 223-226. [Entire volue: Pp. 198-292 + two folded plates]. First printing of Jacobi's accouncement of the Rodrigues's formula (formerly called the Ivory-Jacobi formula). Rodrigues's formula is a formula for Legendre polynomials independently introduced by Olinde Rodrigues in 1816 and Sir James Ivory in 1824 and Carl Gustav Jacobi in 1827 [The present]. The name "Rodrigues formula" was introduced by Heine in 1878, after Hermite pointed out in 1865 that Rodrigues was the first to discover it, and is also used for generalizations to other orthogonal polynomials.

Library stamp to free front end-paper and title-page. Minor bumping to extremities. A nice and clean copy. [Mentioned article:] Pp: 1288-1295. [Entire issue: 837-1658]. First publication of Khang and Sze's seminal and exceedingly influential paper on Floating Gate MOSFET. The technology is today used in flash memory cards. "In 1967, Kahng and Sze reported the first floating-gate structure as a mechanism for nonvolatile information storage. Since then, floating-gate transistors have been used widely to store digital information for long periods in structures such as EPROMs, EEPROMs, and Flash memories." (Hasler, Paul. FLOATING-GATE DEVICES, (1) p.).

Tübingen, Max Niemeyer, 1962. 8vo. Orig. full brown cloth, original dust-jacket. Near mint copy. VII, (1), 189 pp. First edition of Heidegger's important interpretation of Kant's "System aller Grundsätze des reinen Verstandes" from "Kritik der Reinen Vernunft". The work is founded on the basis of a lecture-course given by Heidegger in Freiburg in 1935-36 under the title of "Grundfragen der Metaphysik"; the work is translated into English as ""What is a Thing?" and constitutes an in part revision of the notions put forth in his "Kant und das Problem der Metaphysik"."Aus dem Umkreis der Grundfragen der Metaphysik stellen wir in dieser Vorlesung EINE Frage auf. Sie Lautet: "Was ist ein Ding?" Die Frage ist schon alt. Das stets Neue an ihr ist nur, dass sie immer wieder gefragt warden muss." (p.1).As much as this is an interpretation of Kant's notion of "thing", it equally presents us with Heidegger's own philosophy on this metaphysical question.

Bristol, Pelican/Penguin book, 1955. Small8vo. In the original blue and white wrappers. 230 pp. A nice and clean copy with some sunning. First edition, presentation-copy for Quine, of Körner's influential work on Kant. With the following presentation-inscription from Körner: "To W. V. Q. / With Kind wishes, / S. K.". A letter dated the "27th May, 1955", accompanies the book; it reads as thus "Dear Quine, / I Know that the enclosed is not/ really your cup of tea. But sending/ it to you gives me a good reason/ for sending you my good wishes. / Yours sincerely, / S. Körner". The book was written for laymen which meant that Kant was introduced for a broader audience and was rediscovered and reintroduced to the English-speaking work after the Second World War.

Stamp to front free end-paper and titlepage, otherwise fine and clean. Pp. 375-389. [Entire volume: VIII, 917 pp.]. First printing of London's early paper on Gauge Theories and Weak Interactions in which London anticipated many of Weyl and Pauli's ideas on the same subject."In the face of such elementary experimental evidence, it must have been an unusually strong metaphysical conviction that prevented Weyl from abandoning the idea that Nature would have to make use of the beautiful geometrical possibility that was o?ered. He stuck to his conviction and evaded discussion of the above-mentioned contradictions through a rather unclear re-interpretation of the concept of "real state", which, however, robbed his theory of its immediate physical meaning and attraction." (From the present paper).

A very nice and clean copy externally as well as internally, near mint. Pp. 366-368. [Entire issue: 361-414]. First edition of this groundbreaking paper in which the first demonstration of a coherent light emission from a semiconductor diode or laser diode is presented. The semiconductor laser is built upon Gallium arsenide (GaAs) which is a compound of the elements gallium and arsenic. It is a III/V semiconductor, and is used in a wide variety of devices such as microwave frequency integrated circuits, monolithic microwave integrated circuits, infrared light-emitting diodes, laser diodes, solar cells, and optical windows.Later advances and improvements in materials has made the injection laser a fundamental and essential device in many important systems such as DVD- and CD-players.

Minor bumping to extremities. A nice and clean copy. Pp. 560-603. [Entire volume: (6), 754 pp.]. First edition of the influential paper on television signals. Gray was highly influential in the development of television and conducted pioneering research in this field. "The design of a television system, once the fundamental principles are understood, involves a detailed consideration of the methods by which the several important functions are to be performed.(1) In the present system the initial signal wave is obtained by sweeping a spot of light over the subject in parallel lines completely scanning it once every 18th of a second. The light reflected is collected by large photoelectric cells which control the transmitted current." (From the introduction to the present paper)."A spotlight scanning method was adopted (in the present paper) to illuminate the subject, the beam of light being obtained from a 40A Sperry arc. Three photoelectric cells of the potassium hydride, gas-filled type were specially constructed and utilised to receive the reflected light from the subject. At that time they were probably the largest cells that had ever been made and presented and aperture of 120 square inches." (Burns, R. W.

IV, 600.] First printing of Hilbert's "Habilitationsschrift", a fundamental work on algebraic invariants. With this he meant to revolutionize the feld by several new methods thatplay no part in the 1888 proof but would reappear to some extent in Hilbert’s (1891-92; 1893) response to Gordan’s criticism. By that time Hilbert’s resultsplus further ones by Gordan would solve Gordan’s problem.

Pp.189-205. [Entire volume: IV,420 pp]. First appearance of Lalandé important paper in which the "Landé interval rule" was introduced for the very first time."Lalandé interval rule states that when the spin-orbit interaction is weak enough to be treated as a perturbation, an energy level having definite spin angular momentum and orbital angular momentum is split into levels of differing total angular momentum, so that the interval between successive levels is proportional to the larger of their total angular momentum values."

Entire volume offered in the original blue wrappers with owner´s stamps to front wrapper. A very fine and clean copy. Pp. 590-1. [Entire issue: Pp. 299-592.]. First printing of Kerst's important paper in which a proposal for a collider (Particle-Antiparticle Collider) is presented for the first time. "The beginning of the subject can be traced back to a study by Kerst and collaborators (1956). (Pais. Inward Bound, p. 574.). Colliders are today absolutely fundamental in both applied and theoretical physics."The real beginning of colliding beams comes in a paper by Donald Kerst et al., published as a letter to the editor in the Physical Review in early 1956 [the present paper]. Kerst was the leader of a Midwestern Universities Research Association (MURA), which was the training ground for so many of the important accelerator physicists of the 1960s and 1970s. [...] Kerst and his colleagues had recognized in the relativistic case the enormous advantage of colliding beams over the fixed-target technique in attaining very high energy." (Hoddeson. The Rise of the Standard Model, 1997, p. 263).
