Paris, Firmin Didot. 1826-30. Large 4to. (37 x 27 cm.). 2 volumes, both in the original printed yellow boards. Spines rebacked and with wear amd missing some of the paper. Upper part of back hinge on vol. 2 partly detached. Previous owner's name to front free end-paper. Marginal brownspotting throughout. XX,129,XXII,(130)-318 pp., and 62 engravings, of which 33 are text illustrations (3 of these coloured and 1 in two colours). Printed on thick, fine paper. First edition (the French and the German edition published simultaneously) of Bröndsted's magnum opus, his pioneering "Travels and Archaeological Researches in Greece". The work is based on Bröndsted's extensive travels in Greece, and especially the second part, which contains a major study of the Parthenon, is of great significance. "Bröndsted was trained in Denmark as an archaeologist and philologist. After travelling in France and Italy for some years he left Italy in 1810 on the company of Haller van Hallerstein, Linckh and Stackelberg with the intention of exploring Greece and Asia Minor. This group was involved in the excavations at Aegina, and together with Cockerell and Foster they also excavated at Bassae." (Blackmer, 214). Graesse I,546. Brunet I,1273.

The papers represents one of the first announcements of Berzelius' discovery of the fixed chemical proportions, determining the weights and valencies of the various constituent elements in inorganic compounds. The papers were published at the same time in Swedish, German (both here in Annalen and in Schweiger's Journal), and in French. By running many hundreds of analysis of chemical compounds he gave so many examples of the law of definite proportions that the world of chemistry could no longer doubt its validity, and in so doing he gave experimental evidence to the atomic theory. He hereby laid a solid fundation for the further development of chemistry. A reprint is found in Ostwald's Klassiker der exakten Wissenschaften, No. 35.According to Söderbaum (Jac. Berzelius, 2, p.12) "It was a giant work, one of the most importent in the history of chemistry, which was here presented. One is even more impressed when one remembers that it was a pioneer undertaking in every sense of the term. Analytic and synthetic methods existed before Berzelius' time, to be sure, but there were no precise methods of the sort which he required. They all had to be elaborated at the cost of time and labour."(J. Erik Jorpes "Jac. Berzelius", p.45)."In general Berzelius's efforts were directed toward the consolidation and extension of the atomic theory. He improved chemical analysis and determined the composition of a large number of compounds, thus verifying the laws of constant and multiple proportions and furnishing the most accurate equivalent weights then available. By ingenious methods he arrived at the correct atomic composition of most common substances, and thus was enabled to draw up (in 1826) a table of atomic weights very nearly identical with the modern one."(Leicester & Klicktein "A Source Book in Chemistry", p. 258).Parkinson "Breakthroughs", 1810-20 C.

Matthias Claudius (1740-1815) was a German poet, who is now mostly known for his "Wandsbecker Bothe", the famous newspaper that between 1771 and 1775 appeared as the first popular periodical to also contain stories and articles presented for a wider audience belonging to different educational levels.Claudius had studied theology and political science and later became the private secretary of Count Ulrich Adolph. The Count sent him to Copenhagen, where he stayed for a number of years and made the acquaintance of Friedrich Gottlieb Klopstock, who stimulated his literary longings. From 1768 he worked as an editor for Klopstock's brother in Hamburg, where he met Herder and Lessing, two of the most influential thinkers of the time. In 1771 he went on to Wandsbek, where he came to edit the newspaper of commerce, "Der Wandsbecker Bothe", which had been initiated by Schimmelman. It is under the editorship of Claudius that the paper becomes famous all over Germany, and it is he, who turns it into the first popular newspaper of the country. The paper only ran from 1771 till 1775, and after that Claudius published his own writings under the name of "Der Wandsbecker Bote" and the pseudonym "Asmus".This is a beautifully printed and illustrated work that contains many famous pieces.

Berlin, Julius Springer, 1929. 8vo. Bound in contemporary halfcloth. In "Zeitschrift für Physik", Vol. 53, 1929. Entire volume offered. Library stamp to title page, otherwise fine and clean. Pp. 840-856. [Entire volume: VII,(1),889,(1) pp.] First edition of the landmark paper in which Szilard solved the puzzle of Maxwell's demon and discovered a theoretical model that serves both as a heat engine and information engine, establishing the connection between entropy and information. "This work is now considered to be the earliest known paper in what became the field of "information theory". (Lanouette, Genius in the Shadows: A Biography of Leo Szilard, the Man Behind the Bomb). In the philosophy of thermal and statistical physics, Maxwell's demon is a thought experiment created by Maxwell to show that the Second Law of Thermodynamics has only a statistical certainty. "Maxwell's demon was first mentioned in a letter written to Tait in 1867. Maxwell was one amongst a number of researchers in the developing field of thermodynamics who was interested in seeking an understanding of thermal phenomena in terms of an underlying atomic physics. However, unlike Boltzmann and Clausius, who were attempting to prove the law of entropy increase from such atomic physics, Maxwell had realised that if thermodynamics was ultimately grounded in atomic theory, then the second law of thermodynamics could have only a statistical validity." (SEP). Szilard (In the present paper) attempted to investigate this special case of intelligently operated devices by considering a box containing only a single molecule. He argued that in order to achieve the entropy reduction, the intelligent being must acquire knowledge of which fluctuation occurs and so must perform a measurement. The second law would not be threatened provided there was a compensating cost to performing this measurement, regardless of the character of the intelligent being."Claude E. Shannon, who spelled out detailed relationship between information and entropy in the 1950s, also later acknowledged that Szilard's paper had proposed the basis for his new field study."

Marcel Vertès (1895 -1961) was a magnificent and very versatile artist. He was a costume designer, portraitist, muralist, satirist, ceramicist, author and illustrator, perhaps most generally known as the academy award winning costume designer for John Huston's "Moulin Rouge" from 1952 and for his classic murals at the Café Carlyle at the Carlyle Hotel in New York. Vertès was Born in Budapest in 1895. After serving his country in World War I, he abandoned plans to study law and made his way to Paris to become an artist. In 1940 he left Paris for New York where he set up a studio on West 57th Street. In the late 1950'ies, he returned to Paris, where he died in 1961, having served on the jury of the Cannes Film Festival.

London, Richard Taylor, 1834-35. 4to. No wrappers as extracted from "Philosophical Transactions" 1834 - Part II. and 1835 - Part I. Both titlepages to the volumes present.Pp. (2),247-308 a. (2),95-144. Both papers clean and fine. First appearance of these two groundbreaking papers in which Hamilton carries further the dynamics of Lagrange by expressing the kinetic energy in terms of the momenta and the co-ordinates of a system, and discovers how to transform the Lagrangian equations into a set of differential equations of the first order for the determination of of the motion. The Hamilton principle is also called The Principle of "Least Action". The Hamilton Principle as stated in the papers offered here "was the first of his two great "discoveries". he second was the quaternions, which he discovered...1843 nd towhich he devoted most of his efforts during the remaining 22 years of his life."(DSB).Maupertouis, Euler, and Lagrange introduced the principle of "Least Action" covering the science of dynamics, and now Hamilton brought the principle into a form which was capable of expressing all the laws of Newtonian science in a representation as minimum-problems, that is, all gravitational, dynamical and electrical laws could be represented as minimum problems. In 1925 Heisenberg, Born and Jordan showed, that the Hamilton equations are still valid in quantum theoryAlthough formulated originally for classical mechanics, Hamilton's principle also applies to classical fields such as the electromagnetic and gravitational fields, and has even been extended to quantum mechanics, quantum field theory, relativity and criticality theories. Its influence is so profound and far reaching that many scientists regard it as the most powerful single principle in mathematocal physics and place it at the pinnacle of physical science.

Very slight wear to extremities, otherwise a fine and clean copy. Rare in the publisher's binding. P. 151; Pp. 105-6. [Entire volume: LII, 686 pp.]. First printing of this seminal publication in the history of television; it is generally considered the earliest and most important paper in the early development of television. It constitutes the first description of an electronic method of producing television.Responding to an article in the June 4, 1908 issue of Nature by Shelford Bidwell entitled "Telegraphic Photography and Electric Vision," A. A. Campbell Swinton wrote a letter to the editor of Nature proposing a solution to the most pressing problems in achieving "distant electric vision": "This part of the problem of obtaining distant electric vision can probably be solved by the employment of two beams of kathode rays (one at the transmitting and one at the receiving station) synchronously deflected by the varying fields of two electromagnets placed at right angles to one another and energised by two alternating electric currents of widely different frequencies, so that the moving extremities of the two beams are caused to sweep simultaneously over the whole of the required surface within the one-tenth of a second necessary to take advantage of visual persistence." (SWINTON)."The final, insurmountable problems with any form of mechanical scanning were the limited number of scans per second, which produced a flickering image, and the relatively large size of each hole in the disk, which resulted in poor resolution. In 1908 a Scottish electrical engineer, A. A. Campbell Swinton, wrote that the problems 'can probably be solved by the employment of two beams of kathode rays' instead of spinning disks. Cathode rays are beams of electrons generated in a vacuum tube. Steered by magnetic fields or electric fields, Swinton argued, they could 'paint' a fleeting picture on the glass screen of a tube coated on the inside with a phosphorescent material. Because the rays move at nearly the speed of light, they would avoid the flicker problem, and their tiny size would allow excellent resolution. Swinton never built a set (for, as he said, the possible financial reward would not be enough to make it worthwhile)..." (Britannica). Siers & Siers, Early Television no 366.

London, Harrison and Sons, 1934 a. 1935. Royal8vo. Bound in 2 contemp. full cloth. Gilt lettering to spine. A stamp on verso of titlepages. In: "Proceedings of the Royal Society", Series A, Vol. 146 and vol. 149. VI,942 pp. + VIII,600 pp. (Entire volumes offered). The joint papers: pp. 483-500 (1934) and pp. 522-558 (1935). These seminal papers constitutes the description of the first realization of artificial radioactivity produced by neutron bombardment, and it is the first demonstration of neutron-induced radioactivity. These highlights and his many other results have left their imprint on the most diverse parts of physics. Fermi was awarded the Nobel prize in 1938 for these discoveries."Acting on this idea, (Fermi reasoned that neutrons should be more effective than alpha particles in producing radioactive elements because they are not repelled by the nuclear charge and thus have a much greater probability of entering the target nuclei) Fermi bombarded several elements of increasing atomic numbers with neutrons. He hoped to find an artificial radioactivity produced by the neutrons. His first success was with fluorine. The neutron source was a small ampul containing beryllium metal and radon gas. The detecting apparatus consisted of rather primitive Geiger-Müller counters. Immediately thereafter Fermi, with the help of Amaldi, D’Agostino, Rasetti, and Segrè, carried out a systematic investigation of the behavior of elements throughout the periodic table. In most cases they performed chemical analysis to identify the chemical element that was the carrier of the activity. In the first survey, out of sixty-three elements investigated, thirty-seven showed an easily detectable activity. The nuclear reactions of (n, a), (n, p), and (n, ?) were then identified, and all available elements, including uranium and thorium, were irradiated. In uranium and thorium the investigators found several forms of activity after bombardment but did not recognize fission. Fermi and his collaborators, having proved that no radioactive isotopes were formed between lead and uranium, put forward the natural hypothesis that the activity was due to transuranic elements. These studies, which were continued by Otto Hahn, Lise Meitner, Irène Joliot Curie, Frédéric Joliot, and Savitch, culminated in 1938 in the discovery of fission by Hahn and Fritz Strassmann."(DSB)."The present papers are a summary of these letters (the letters from the team communicated almost weakly to "Ricerca Scientifica") for the English speaking readers. "When we (Fermi and Segre) went to Cambridge, we discussed with him (rutherford), in great detail, our work. The work which had been accomplished up to that date by our group is summarized in a paper which was presented by Lord Rutherford to the Royal Society (Paper No. 98). The manuscript of this paper had been prepared in Rome and delivered to him in Cambridge. he read it immediately with great attention, made several corrections to improve our English, and turned it over to the Royal Society. I asked him whether it would be possible to obtain a speedy publication and he immediately answered "What did you think I was President of the Royal Society for ?" (Collected Papers of Enrico Fermi, Vol. I, p. 641).Volume 149 contains the importent joint paper on SUPERCONDUCTIVITY by the brothers FRITZ And H. LONDON "The Electromagnetic Equations of the Superconductor", pp. 71-88."In 1933 shortly before Heinz London joined his brother at Oxford, W. Meissner and R. Ochsenfeld made a startling discovery. It was well known that currents in superconductors flow in such a way as to shield points inside the material from changes in the external magnetic field. This indeed is an obvious property of any resistance less medium, fully discussed by Maxwell in 1873 long before the discovery of superconductivity. But a superconductor does more. Whereas a zero resistance medium only counteracts changes in the field, it actually tends to expel the field present in its interior before cooling.... The London quickly saw its implications and in 1935 published a joint paper on the electrodynamics of superconductors, in which they replaced (paper by Deaver and Fairbanks) by a new phenomenological equation connecting the current with the magnetic rather than the electric field...

First edition of these 2 papers which unifies the Euclidean and Non-Euclidean geometries, by reducing the differences to expressions of the "distance function", and introducing the concepts "parabolic", "elliptic" and "hyperbolic" for the geometries of Euclid, Riemann and of Lobatschewski, Gauss and Bolyai. He further eliminates Euclid's parallel-axiom from projective geometry, as he shows that the quality of being parallel, is not invariant under projections.Klein build his work on Cayley's "distant measure" saying, that "Metrical properties are not properties of the figure per se but of the figure in relation to the absolute." This is Cayley's idea of the general projective determination of metrics. The place of the metric concept in projective geometry and the greater generality of the latter were described by Cayley as "Metrical geometry is part of projective geometry." Cayley's idea was taken over by Felix Klein....It seemed to him to be possible to subsume the non-Euclidean geometries, hyperbolic and double elliptic geometry, under projective geometry by exploring Cayley's idea. He gave a sketch of his thoughts in a paper of 1871, and then developed them in two papers (the papers offered here).Klein was the first to recognize that we do not need surfaces to obtain models of non-Euclidean geometries....The import which gradually emerged from Klein's contributions was that projective geometry is really logically independent of Euclidean geometry....By making apparent the basic role of projective geometry Klein paved the way for an axiomatic development which could start with projective geometry and derive the several metric geometries from it."(Morris Kline).The offred volumes cntains other importen mathematical papers by f.i. by Klebsch, Lipschitz, Neumann, Noether, Thomae, Gordan, Lie, Du Bois-Raymond, Cantor (Über trigonometrische Reihen),etc.(Sommerville: Bibliography of Non-Euclidean Geometry p. 45 a. 49.)
