Leipzig, B.G. Teubner, 1890. 8vo. Original printed wrappers, no backstrip and a small nick to front wrapper. In "Mathematische Annalen. Begründet durch Rudolf Friedrich Alfred Clebsch. XXXVII. [37]. Band. 4. Heft." Entire issue offered. Internally very fine and clean. [Klein:] Pp. 544-72; 573-90. [Entire issue: Pp. pp. 465-604]. First printing of Klein's important contribution to non-Euclidean geometry. Klein saw a fundamental unity in the subject of non-Euclidean geometry. Rather than a heterogeneous collection of abstruse mathematics, non-Euclidean geometry was in Klein's view a "concrete discipline".For over two millennia geometry had been the study of theorems which could be proved from Euclid's axioms. However, in the beginning of the 19th century it was proved that there exist other geometries than that of Euclid. Motivated by the emergence of the new geometries of Bolyai, Lobachevsky, and Riemann, Klein proposed to define a geometry, not by a set of axioms, but instead in terms of the transformations that leave it invariant; according to Klein, a geometric structure consists of a space together with a particular group of transformations of the space. A valid theorem in that particular geometry is one that holds under this group of transformations. This controversial idea did not only give a more systematic way of classifying the different geometries, but also gave birth to new geometric structures such as manifolds.

An excellent, near mint copy. (6), 129 pp. First edition of Ryle's second main work, in which he sets out to discuss true issues and dilemmas of the actual life of man.Gilbert Ryle (1900-1976) was an immensely influential British philosopher, who represented the ordinary language philosophers so strongly influenced by Wittgenstein. He was also greatly influenced by Bertrand Russell and his theory of descriptions and the conception of analysis embodied in that. Influenced by the idea of misleading expressions, which can be sorted out only with the help of logic, Ryle establishes his view of philosophy as cartography. Just like the inhabitants of a space on earth can talk about that space to the cartographer, so the ordinary user of a language can talk to the philosopher. However, in both cases the practical knowledge of the ordinary user must be transformed into the universal terms of the expert in order for him to say anything meaningful.In his "Dilemmas" Ryle, with the aid of the tools of the practicing philosopher, solves a number of puzzles for everyday man and makes him understand the meaning and use of philosophy in general.

København, Høst & Søn, 1928. 8vo. Uncut in the original printed wrappers. A bit of minor wear to extremities and a bit of wear to spine. An excellent, very nice and clean copy. 362, (1 - errata) pp. The rare first edition of Hjelmslev's first major book, in which he anticipates many of the views that led to the foundation of the seminal theory of language "Glossematics" which he framed together with H.J. Uldall. This foundational work treats the general laws of the formation of language and is an invaluable source for the understanding of Hjelmslev's linguistic theories. Hjelmslev had studied comparatvive linguistics in Copenhagen, Prague and Paris, when in 1931 he co-founded the "Cercle Linguistique de Copenhague", also known as the "Copenhagen School of Linguistics" with Viggo Brøndal (1887-1942). Hjelmslev's linguistic theories formed the basis of this seminal school, which soon became one of the most important centres of structuralism in the world. The single most important cornerstone of this internationally highly influential school was the new theory on language that Hjelmslev had developed together with Hans-Jørgen Uldall. This theory consisted in the double duality of the linguistic sign and is now known as "Glossematics", a now generally used term, which was coined by the two. "Glossematics" represents an attempt to analyze the contents and the form of language on a coherent basis. Hjelmslev's theories of semiotics became hugely influential, and virtually all of the greatest European thinkers interested in language and theories of language throughout the 30s, 40s, 50s, 60s and 70s were hugely influenced by Hjemslev, whose theories remain of seminal character to this day.

Library labels pasted on to front end-papers and stamps to title page, otherwise fine. Pp. 489-520. [Entire volume: VIII, 972 pp + 5 folded plates]. First printing of Epstein's seminal paper in which he was able to derive equations for the linear and quadratic Stark effect in hydrogen."In his classic paper on the theory of the Stark effect [The present], the splitting of the spectral lines in a hydrogen atom by a strong electric field, he worked out the quantization rules in an invariant form and then used them to calculate the splitting of the hydrogen lines. The splitting effect, first observed by Johannes Stark in 1913, could not be explained along classical lines. Showing that Niels Bohr's Quantum description of the hydrogen atom could solve the problem made Epstein's reputation as a theoretical physicist. The match between his theoretical predictions and Stark's data furnished striking support for the RutherfordBohr atomic theory.Working independently, the German astronomer Karl Schwarzschild publicly announced the solution to the same problem one day after Epstein's paper appeared. (As Epstein relates it, Schwarzchild initially had the wrong formula. He corrected it after seeing an announcement of the development of Epstein's result.) Epstein's other contributions to the development of the quantum theory of atomic structure between 1916 and 1921 ranged from his extension of Bohr's theory to nonperiodic motions, including beta decay and the photoelectric effect, to the interference of spectral lines."

Berlin, Offentliches Leben, 1937. 8vo. In the original wrappers. With repair to lower part and lower right corner bended, otherwise a very nice and clean copy. [Hermann:] Pp. 309-398. [Entire issue: Pp. 273-504, (3) + frontispeice depicting Jakob Friedrich Fries.]. First printing of Hermann's publication on the historical development and foundation of physics. Today she if famous for her pioneering work with respect to the interpretation of quantum theory, the present paper being her most extensive on the philosophical aspects of the development of research in physics.Attempts to interpret and understand what was then new and very puzzling physics were of great contemporary importance when Grete Hermann entered the field, and her work in physics was mainly related to the interpretation of quantum mechanics. More specifically, her main work in physics was on the philosophical foundations of quantum mechanics, the significance of modern physics for the theory of knowledge, and causality in physics. She was one of the active early contributors to the historic debates on causality in quantum mechanics, and on the completeness of quantum mechanics and its description of reality.Hermann's work during the 1930s reveals the influence of her background in the neo-Kantian school, yet it also owes much to the way in which Heisenberg and Weizsäcker had interpreted Bohr's doctrine of the indispensability of classical concepts in the description of experience.Heisenberg has written that Grete Hermann came to Leipzig for the purpose of challenging the philosophical basis of atomic physics. Heisenberg devoted an entire chapter of his book "Physics and Beyond: Encounters and Conversations" to a reconstruction of discussions that he had on quantum mechanics and Kantian philosophy with Grete Hermann and Carl Friedrich von Weizsäcker.

Lancaster, American Institute of Physics, 1963. Lex8vo. Volume 130, 15 June, No. 6, of "The Physical Review", Second Series. Entire volume offered in the original printed blue wrappers. Previous owner's stamp to front wrapper. Wear to spine and extremities. Internally fine and clean. Pp. 2529-38. [Entire issue: Pp. 2135-2622]. First publication of this seminal paper in which the first thorough development of the quantum theory of optical coherence was presented. The present paper led directly to Glauber being awarded the Nobel Prize in physics in 2005 "for his contribution to the quantum theory of optical coherence". His theories are today widely used in the field of quantum optics."After the discovery of the maser and the laser in the sixties new ideas for quantum effects of the radiation field were in the air. However, there was no theory for their observation. It was only in 1963 that Roy [Glauber] had developed the quantum theory of optical coherence [in the present paper]. Here the concept of coherence state plays a central role. Coherent states had been proposed for the first time by Erwin Schrödinger in order to show that a wavepacket needs not always to be bound to spread. The coherent state became the crucial tool for Roy's theory of optical coherence. In particular, he could show that for coherent fields all correlation functions factorize." (Scully. Quantum theory of optical coherence. 2009. P. xv.).Glauber's work was essential for understanding and the further development of the laser.

Baltimore, Williams & Wilkins Company, 1908. Royal8vo. Offprint, uncut, unopened in the original printed wrappers. Reprinted from "The Journal of Experimental Zoölogy", Vol. V [5], No. 4. Light miscolouring to front wrapper, otherwise a very fine and clean copy. 577-632 pp. Scarce offprint of Jennings' important work in which he published the results of his investigations of heredity and selection in Paramecium. "Most of this lons paper was devoted to a study of the effects of environment and growth upon the sizes of Paramecium, both effects were found to be quite large. (Provine, The Origins of Theoretical Population Genetics, P. 100)"Herbert Spencer Jennings was widely recognized and greatly respected not only as a pioneering biological investigator but also as a thinker, philosopher, and educator . He was a master of the art of setting forth simply, clearly, and vividly, in print and in public lectures, the current state of genetics and general biology and of recognizing and pointing out their implications for the general public and for specialists in various disciplines. "Herbert Spencer Jennings (1868-1947), American botanist who was trained at Illinois Normal School and the University of Michigan, then spent a year studying protozoans with Max Verworn at the zoological station in Naples. In the early twentieth century, Jennings began studying inheritance and evolution in protozoans and introduced new experimental methods for laboratory study. By 1920 he had left the laboratory to popularize genetics and harmonize the relationship between biology, religion, and the humanities.
