London, Macmillan and Co., 1895-96. Royal8vo. Bound in contemporary half calf with five raised bands and two black leather title labels with gilt lettering to spine. In "Nature", November - April, 1895-96, Vol. LIII [53]. Pp. 274-6. [Entire volume: XL, 624 pp.]. First printing of the English translation (translated by Arthur Stanton) of Göntgen's seminal paper in which he presented his groundbreaking discovery of X-rays; the foundation of roentgenology and thereby unveiling a new form of matter and offering a new revolutionary method for medical diagnosis."Translations of Rontgen's paper soon started to appear, beginning with an English translation in Nature on 23 January. By 20 Febrary Nature was commenting that "so numerous are the communications being made to scientific societies that it is difficult to keep pace with them, and the limits of our space would be exceeded if we attempted to describe the whole of the contributions to the subject, even at this early stage." (Bakker, p. 319)"Their [X-rays] importance in surgery, medicine and metallurgy is well known. Incomparable the most important aspect of Röntgen's experiments, however, is his discovery of matter in a new form, which has completely revolutionized the study of chemistry and physics. Laue and the Braggs have used X-rays to show us the atomic structure of crystals. Moseley has reconstructed the periodic table of the elements. Becquerel was directly inspired by Röntgen's results to the investigation that discovered radio-activity. Finally J. J. Thomson enunciated the electron theory as a result of investigating the nature of the X-rays." (DSB)."On Friday, 8 November 1895, Röntgen first suspected the existence of a new phenomenon when he observed that crystals of barium platinocyanide fluoresced at some distance from a Crookes tube with which he was experimenting. Hertz and Lenard had published on the penetrating powers of cathode rays (electrons), and Röntgen thought that there were unsolved problems worth investigation. He found time to begin his repetition of their experiments in October 1895. Although others had operated Crookes tubes in laboratories for over thirty years, it was Röntgen who found that X rays are emitted by the part of the glass wall of the tube that is opposite the cathode and that receives the beam of cathode rays. He soon discovered the penetrating properties of the rays, and was able to produce photographs of balance-weights in a closed box, the chamber of a shotgun, and a piece of nonhomogeneous metal. The apparent magical nature of the new rays was something of a shock even to Röntgen, and he, naturally, wished to be absolutely sure of the repeatability of the effects before publishing. The first communication on the rays, on 28 December, was to the editors of the Physical and Medical Society of Würzburg, and by 1 January 1896 Röntgen was able to send reprints and, in some cases, photographs to his friends and colleagues. Emil Warburg displayed some of the photographs at a meeting of the Berlin Physical Society on 4 January. The Wiener Presse carried the story of the discovery on 5 January, and on the following day the news broke around the world. The world's response was remarkably swift, both the general public and the scientific community reacting in their characteristic ways. For the former, the apparent magic caught the imagination, and for the latter, Crookes tubes and generators were promptly sold in great numbers.After a royal summons, Röntgen demonstrated the effects of X rays to the Kaiser and the court on 13 January. He was immediately awarded the Prussian Order of the Crown, Second Class.In March 1896, a second paper on X rays was published, and there followed a third in 1897, after which Röntgen returned to the study of the physics of solids. " (DSB)"Aside from its obvious applications, Roentgen's discovery galvanized the world of physics and led to a rash of further discoveries that so completely overturned the old concepts of the science, that the discovery of X-rays is sometimes considered the first stroke of the Second Scientific Revolution. (The First Scientific Revolution is, of course that which included Galileo and his experiments on falling bodies). Within a matter of months, investigations of X rays led to the discovery of radioactivity by Becquerel....The importence of the discovery was well recognized in its own time. In 1896 Roentgen shared the Rumford Medal with Lenard and in 1901, when Nobel Prizes were set up.the first to be honoured with a Nobel Prize in Physics was Roentgen." (Asimov).

Berlin, Reuther & Reichard, 1922. 8vo. Uncut in the original grey printed wrappers. Tear at hinges, but no loss. Carnap's signature to title-page. 87 pp. Presumably Carnap's own copy, with his signature/owner's inscription to title-page, of the first edition of Carnap's first publication, his doctoral dissertation. Printed in Kant-Studien, Ergänzungshefte, Nr. 56. Issued by H. Vaihinger, M. Frischeisen-Kähler and A Liebert. 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. In Jena he was appointed Professor of Mathematics, though his main interest at that time was in physics. By 1913 he planned to write his dissertation on thermionic emission, but this was interrupted by World War I, where he served at the front until 1917. Afterwards he studied the theory of relativity under Einstein in Berlin, and he developed the theory for a new dissertation, namely on an axiomatic system for the physical theory of space and time. He thus ended up writing the important dissertation under the direction of Bouch on the theory of space (Raum) from a philosophical point of view. The dissertation was submitted in 1921, and, due to the clear influence from Kantian philosophy, it was published the following year in this supplement to the "Kant-Studien". After the publication of his first work, Carnap's involvement with the Vienna Circle began to develop. He met Reichenbach in 1923 and was introduced to Moritz Schlick in Vienna, where he then moved to become assistant professor at the university. He soon became one of the leading members of the Vienna Circle, and in 1929 he, Neurath, and Hahn wrote the manifest of the Circle.As the title indicates, "Der Raum" deals with the philosophy of space. Partly influenced by Husserl, under whom he studied at Freiburg, Carnap poses the question whether our knowledge of space is analytic, synthetic a priori or empirical. His answer is that it depends on what is meant by "space", and thus differentiates between three kinds of theories of space: Formal (which is analytic [a priori]), intuitive (which is synthetic a priori), and physical (which is empirical [or synthetic aposteriori]). He compares this division of space with that of geometry into: projective, metric and topological. This, of course, anticipates much of his later philosophy, and some of his theories developed in this paper became the official position of logical empiricism on the philosophy of space. In this work he also develops a formal system for space-time topology, which became quite influential.

Koppenhagen (Copenhagen), (Mads Vingard, sold by Heinrich Waldkirch), 1597. 4to. In contemporary limp vellum. Binding soiled and miscoloured, edges of boards missing small part of vellum. Leaf O-T2 with hole from burning in inner margin(Primarily affecting (P3-S3). Dampstain in upper margin. 104 ff (of which two are blank). First edition of August Erich's first-hand account of Christian IV's coronation in Copenhagen in 1596. His work offers a detailed account about the proceedings, the participants and the significance of the event. "August Erich calls himself "German Secretary to his Royal Majesty". He was present at the ceremonious coronation of King Christian IV August 29, 1596, and describes the various processions, festivities and tournaments. He also records the names of the persons taking part in the coronation and how they were dressed." (Thesaurus I, 230). Christian IV was crowned on 29 August 1596 at the Church of Our Lady in Copenhagen by the Bishop of Zealand, Peder Jensen Vinstrup (1549–1614). He was crowned with the new Crown Regalia which had been made for him by Dirich Fyring. Christian IV (1577-1648) is probably the most famous - and infamous - king in the history of Denmark. On the one hand, he is known as the longest reigning monarch, as the patron and creator of some of the country's most significant and spectacular buildings. On the other hand, he is also known as the king who definitively crushed Denmark's dreams of being a great power. The following year, the work was published in Danish.

With titlepage to the volume (1733/1735). Margins of titlepage with a few brownspots. First appearance of these milestone papers in the histroy of electricity in which Dufay explains his discovery of two kinds of electricity and the relation between them, attraction and repulsion, shocks and sparking, and the full recognition of electrostatic repulsion. He formulates the two-fluid theory of electricity. He further showed that "not all bodies can become electrified themselves" (by friction) and went on to show, "that they can all acquire a considerable (electrical) virtue when the tube (of rubbed) glass), wood, metals or liquids are brought near them,", provided only that they are insulated by beiing stood on "a support of glass or of sealing-wax".Dufay "TRANSFORMED A COLLECTION OF MISCELLANEOUS WEEDS INTO THE FIRST GARDEN OF EUROPE" (Heilbron)"Dufay's substantive discoveries - ACR, the two electricities, shocks and sparking - are but one aspect, and perhaps not the most significant, of his achievement. His insistence on the impiortence of the subject, on the universal character of electricity, on the necessity of organizing, digesting and regulariizing known facts before grasping new ones, all helped to introduce order and professionel standards into the study of electricity at precisely the moment when the accumulation of data began to require them. He foundthe subject a record of often capricious, disconnected phenomena, the domain of the polymaths, textbook writers, and prfesional lecturers, and left a body of knowledge that invited and rewarded prolonged scrutinity from serious physicists."

Berlin, Springer, 1932. 8vo. Orig. full yellow cloth. with orig. printed dustjacket. Jacket with a few minor small tears.

(8),262,(2) pp. With many annotations in small pencil by Niels Arley throughout. First edition. In the early years of quantum mechanics several distinct formulations were developed; Heisenberg's matrix mechanics, Schrödinger's wave mechanics, and Dirac's more general transformation theory. However these theories lacked strict mathematical rigor (only much later through Schwartz's theory of distributions did Dirac's theory achieve this). Quantum mechanics is one of the fields of science which was fortunate to attract the attention of a mathematician of von Neumann's character. Von Neumann showed, in a paper published 1927, how generalized infinite-dimensional Euclidean spaces (function spaces) and linear operators provide the proper mathematical framework for quantum mechanics. Von Neumann was strongly influenced by Hilbert's program of axiomatizing the fields of science. The axiomatic approach which von Neumann takes in his theory has ever since dominated modern physics and functional analysis, and it was von Neumann who coined the term 'Hilbert space'. Von Neumann's work in this field culminated in this monograph which in addition to the earlier paper includes his important considerations, inspired by Bohr and Heisenberg, regarding the problem of measurement, in particular von Neumann's disproof of hidden variables.

Lugduni (Lyon), Seb. Gryphium, 1556. 8vo. Cont. full calf. Raised bands, gilt borders on covers. A gilt centerpiece on both covers. Leather at upper compartment of back gone and a nick to lower compartment. Corners bumped and worn, somewhat rubbed. 567,(71) pp. Old repair to foot of title, no loss of text. Some old ownership inscriptions on endpapers and title, 2 old engraved bookplates pasted on front-and endpapers. Internally with a few mainly marginal brownspopts and a faint dampstain in lower corners of the first leaves. Woodcut initials. "Somnium" pp. 3-178 having geographical woodcuts in the text and a woodcut map of the old world. Printers woodcut-device on title. Fourth Lyon-edition of Macrobius's 2 main works. In the "Somnium" he uses passages of Cicero's work as mere suggestions to construct a treatise on Neoplatonic philosophy - the most satisfactory and widely read Latin compendium on Neoplatonism that existed during the Middle Ages. Macrobius was one of the leading popularizers of science in the Latin West, and his conception of the world geography as an equatorial and meridional ocean (depicted in the book) dividing the earth into four quarters, dominated scientific thinking on world geography in the Middle Ages. - His "Saturnalia" deals with Roman feasts in form of table-talk at a banquet in Rome, giving information of food and drink and their preparation (Vicaire 986 (ed.1492, Simon p. 547 (ed. 1492)). and is fascinatingly rich in philological, historical, antiquarian and scientific lore, throwing a clear light on the interests and taste of the period. - Adams vol.

Bruxelles, Fr. Foppens, 1699. Small 8vo (12mo). Bound in a beautiful later full calf (ca. 1800) w. five raised bands on back. Gilt back and blindstamped ornamental borders on boards. All edges of boards gilt, and gilt borders on inside of boards. Hinges cracked and boards loosening, inner hinges crudely repaired. A bit of brownspotting, but internally a very nice copy. The very rare Bruxelles-edition, published same year as the first edition (Paris, Barbin). Fénelon's main work, written when he was a tutor to the Duke of Burgundy in order to hold up Ulysses as an example for the young prince. Fénelon was a leader of the Quetism heresy, and in 1699, the year Télemaque appeared, Pope Innocent XII condemned his writings. The true first edition of Fénélon's Télemaque appeared in one volume in 1699 under the title "Suite du quatrième livre de l'Odyssée d'Homère, ou les Aventures de Télémaque, fils d'Ulysse", and containing only half of what we consider Télémaque today. According to Brunet, the first edition was suppressed, and Moetjens printed a pirate-edition (called the second edition) in Haag with the same year and date (June), and a bit later the same year, the second part appeared. Several editions appeared the same year, and Brunet mentions one without printer or Place (but Paris), and the Liége- and Bruxelles-editions. "Dans les différentes éditions que nous venons de décrire dans lesquelles il le soit sont celles de LIÉGE, 1699, et de BRUXELLES, FR. FOPPENS, même date, l'une et l'autre impr. en France, en 2 vol. in-12, et en dix livres." (Brunet II:1212). Foppens also printed an edition in Bruxelles 1700, but that is divided into 16 books. All early editions of this work are scarce, and the first edition is almost impossible to get a hold of. This main work of French literature has been printed numerous times after the author's death (1715), and editions printed before his death, are a great rarity. The later editions were corrected and divided into numerous books, not intended in the original manuscript."Une autre circonstance allait aggrever la situation de l'archevêque de Cambray. Peu de temps après sa condemnation, parut le livre qui l'a rendu le plus populaire et qui, après la "Bible" et l'"Imitation de Jésus-Christ", est un de ceux qui ont eu plus d'éditions: "Les Aventures de Télémaque". (N.B.G. 17:328). The controversial but highly popular work was, among other things, accused of satirically portraying Louis XIV, and thereby publicly humiliating him, -this was probably not the intention, but there is no doubt that the work was critical towards the reigning regime, and put forth many ideas not previously heard of. In true utopian political manner, Fénélon warns against overgrowth of the metropolis and preaches groundbreaking doctrines like free trade, international arbitration etc. He actually foresees the French Revolution as a result of the flourishing despotism so visible in France at the time. Lamartine (in his "Life of Fénélon") describes the saintly poet as the first Radical and the first communist of his century, though not to his own knowledge, and he directly traces the Utopias which produced the revolutions of 1793 and 1848 to his groundbreaking work, "The Adventures of Telemachus". Especially the part "Voyage en Salente" is considered very important for the study of utopian literature, but the entire work is characterized by the attempt to represent people as they might have behaved and might still be, were they governed by sages and saints and according to the laws of God. The work represents a religious ideal where God is always higher than man; it is greatly political, greatly influenced by the appreciation of ancient Greek life, and is designed to evoke the feeling of honour, responsibility and religion in the young prince.

Clausius's paper pp. 481-506. First printing of this MILESTONE PAPER IN THERMODYNAMICS, which together with his paper from 1850, established the second law of thermodynamics. In the offered paper Clausius introduces the symbol T for the universal function of temperature (a + 1) and he introduces the concept of "entropy" (the greek word for 'transformation'), but without using the word (Clausius introduced the word later in 1865), he calls this new theorem "the principle of the equivalence of transformations". This principle paints a dramatic picture of the end of the world, the so-called "heath-death of the universe"."Entropy, on the other hand, of the complementary experience of water seeking its own level, of hot bodies cooling, of springs untensing, of magnetism wearing off and electrical charges leaking away, of a destiny suchThat no life lives forever; - That dead men rise up never; that even the weariest river Winds somewhere safe to sea: a world getting old and running down."(Gillespie in "The edge of Objectivity" p. 400-01.)."Clausius discovered that if he took the ratio of the heat content of a system and its absolute temperature, this ration would always increase in any process taken place in a closed system. (A closed system is one that loses no energy to the outside world and gains no energy from it.) With perfect efficiency, which is never realized in the real world, of course, the ratio would remain constant, but i would never, under any circumstances, decrease."(Asimov). - Parkinson: Breakthroughs 1854 C.

Paris, Victor Masson, Imprimerie de Bachelier, 1848. 8vo. Contemp. hcalf, raised bands, gilt spine. Very light wear along edges. Small stamps on verso of titlepage and on verso of plate.

A few marginal brownspots to P.'s paper. Otherwise fine and clean. First full exposition of Pasteur's first revolutionary paper on the discovery of "molecular assymetry" - also constituting his first published scientific paper. In order to secure priority, Pasteur announced his discoveries first in its preliminary form in a short paper of 4 pages in "Recherches sur le dimorphisme", Comptes rendus hebdomadaires des séances de l' Académie des Sciences, 20 mars 1848, XXVI, pp. 353-355. In the offered form it is the first full treatment of his discoveries."Pasteur came to the conclusion, on one hand, that all tartrates could be regarded as mutually isomorphic, but at the same time - based on Mitscherlich's work - that the sodium ammonium salts of both the tartaric and racemic acids also crystallized isomorphically, which in turn suggested that all racemic and tartaric salts would crystallice identically. An they do crystallice identically, albeit in a very special way Half the crystals of the racemic salts are characterized by a mirror-inverted form."(Hans-Werner Schütt in "Eilhard Mitscherlich")."Another discovery of great importence was made by Pasteur. In 1844 Mitscherlich had stated that the crystals of sodium ammonium tartrate and sodium ammonium racemate were identical, although solutions of the former were found to be active but those of the latter were inactive. Since this statement was contrary to his views on the relation between crystalline form and optical activity, Pasteur examined these salts and found, it is true, that the crystals of the tartrate resembled the other tartrates which he had examined i possessing hemihedral faces arranges in a similar manner. The crystals which was obtained from a solution of the inactive racemate, at the ordinary temperature, were also found, contrary to expectation, to have hmihedral faces...."(Alexander Findley in "A Hundred years of Chemistry", p.59-60).It is related that Pasteur, on making this discovery, rushed from his laboratory and, meeting the lecture assistant in physicss, embraced him, exclaming: "I have just made a great discovery! I have separated the sodium ammonium paratartrate into two salts of opposite action on the plane polarisation of light. The dextro-salt is in all rspects identical with the dextro-tartrate. I am so happy and overcome by suchnervous excitement that I am unable to place my eye again to the polariization apparatus.".Among other importent chemical papers the volume contains Gay-Lussac: Mémoire sur L'Eau Régale. Pp. 203-229.

I pragtfuld fuld håndkolorering. Øverst i midten er indsat Amager og Saltholm i større målestok. Kortet "ligger ned", er orienteret øst/vest. Med kompasrose og vindretninger angivet. Det berømte søkort over Sundet fra Jaillot's "Neptune Francois", men i P. Mortier's samtidige udgivelse heraf fra Amsterdam med tilføjelsen "Levée et Gravée" i kartouchen. Jaillot's to søkort over Danmark gav anledning til en kritik af Jens Sørensens opmåling idet Admiralitete forelagde ham de franske og påtalte, at Sørensens kort næppe kunne være korrekte. Det var de imidlertid. Her er for første gang trykt det mere korrekte Amagerkort, der foranlediger at øen på næsten alle senere kort gengives stor og rund.
