København, (1888-1889). 4to (bd. 1-2) + 8vo (bd. 3). Indbundet i tre samtidige, ensartede, nydelige grønne halvlæderbind med rygforgyldning. Slitage ved kapitæler og ved false. Hjørner stødt. Indvendig pæn og ren. I 2det Bind af dette tidsskrift findes originaltrykket af den først publicerede del af en af den moderne litteraturs hovedværker, Hamsuns "Sult". Heri trykkes for første gang de berømte linier "Det var i den Tid, da jeg gik omkring og sultede i København", indledningen til den roman, der gjorde Hamsun berømt og til det værk, der indvarslede en ny litterær epoke i Europa. "Sult" kom først i bogform to år senere, i 1890, og det er med publikationen af denne del, at Hamsuns ry som en forfatter i verdensklasse bliver slået fast."Knut Hamsuns debutroman fra 1890 er en af de bøger, der har sat skel. Den har virket med til at forme et nyt menneskesyn og en ny skrivemåde. Hamsun hentede stoffet fra sine egne trængselsår, da han uden slægt og venner gik arbejdsløs i Kristiania og kæmpede mod skuffelser, nederlag og sult." (Johannes V. Jensen).Som 27-årig i 1886 blev Hamsun for anden gang reddet fra en sultende tilværelse og sendt til Amerika, denne gang til Chicago, hvor han bl.a. arbejdede som sporvognskonduktør. Da han blev fyret fra dette job og vennerne havde skilliget sammen til en billet hjem, tog Hamsun i forsommeren 1888 tilbage mod Norden, -men han stod ikke af i Kristiania, han tog skibet videre til København. Da han stod og så skibet sejle fra Kristiania, tænkte han på sine nederlag i denne by, og en af den nyere litteraturs vigtigste sætninger indfandt sig i hans hoved: "Det var i den tid, da jeg gik rundt og sultede i Kristiania", -kimen til et af det 20. århundredes litterære hovedværker var lagt, og Hamsun satte sig med det samme på den nærmeste skibskiste og begyndte at skrive. Påvirket af Nietzsche og Dostojevski sad Hamsun i sit loftsværelse på Nørrebro og arbejdede døgnet rundt på sit første mesterværk. Efteråret 1888 stod den første del af monumentalromanen "Sult" færdig, men da Hamsun ikke turde risikere en afvisning fra Danmarks førende kulturperson, Georg Brandes, opsøgte han dennes bror, Edvard, som var chefredaktør på "Politiken". Edvard Brandes fik således æren af at være den første, der anerkendte Hamsuns talent. Til den stærkt forhutlede forfatter sagde han som den første: "Der venter Dem en meget stor Fremtid!" og om det manuskript, han præsenterede ham for: "det var ikke bare talentfuldt som så meget andet, det var mere, noget, der rystede mig." Edvard Brandes var ikke i tvivl om, at dette manuskript skulle trykkes, og da det var for langt til at stå i "Politiken", blev det trykt i tidsskriftet "Ny Jord", og med ét kunne alle, der tidligere havde afvist Hamsun og hans tidlige litterære forsøg, se, hvor stor en forfatter, de havde at gøre med. De tre bind af "Ny Jord" giver et fantastisk indblik i den Nordiske tidsånd i slutningen af det 19. århundrede. Vi finder hér, ud over både førstetrykket af "Sult" og Hamsuns "Kristoffer Janson" ligeledes den første del af den første danske oversættelse af Nietzsches "Saaledes talte Zarathustra", diskussioner og oversættelser af Darwin, bidrag af Strindberg , Høffdings "Om vor Tid og dens Ungdom" etc, etc.

Amsterdam, L. & D. Elzevirios, 1661. 4to. Contemp. full vellum, ms-title on spine. Title in red/black. Engraved portrai of Regius on verso of f 4 (H. Bloemaert pinxit, T. Matha, sculpsit). (44),523,(1- Errata) pp. 2 folded engraved plates (Globus Coelestis a. Orbis Terrarum Typus). Numerous woodcut illustrations in the text, astronomical, mechanical, physical, physiological, anatomical, theory of light, theory of vision etc. etc. Printed on good paper, clean and fine. Third edition (appeared 1651 a. 1654). This is edition having the 2 plates which appears here for the first time and not in the earlier editions.Henricus Regius (in Dutch: Hendrik de Roy) may be recognised today primarily as one of Descartes' correspondents. However, he was also the author of a textbook of natural philosophy, Fundamenta physices (1646), which offered an alternative to Cartesian epistemology and metaphysics. His correspondence with Descartes, and his simultaneous controversy with G. Voetius during the 1640s, reflected Regius' efforts to establish his intellectual independence from scholastic philosophy and Cartesian metaphysics.(Stanford Encyclopedia of Philosophy).Willems, 1274. - Poggendorff II, 587 b.

It contains much new and useful information; it is written with clearness and precision, and better adapted to the purposs of instruction than any similar work which have appeared in the United States since 1800. The modern practice of double entry is clearly exemplified by Turner, and a very trifling revision would render [the present work] one of best elementary treatises on merchants accounts extant" (Foster, The Origin and Progress of Book-keeping).

Bln., Voss, 1767. Two nice, cont., uniform full calf w. five raised bands on backs, coloured title- and tome-labels and richly gilt backs. Traces of use, especially to the bands. Some gilding and part of title-label on vol. one worn off. Internally a bit of soiling, but a good copy on good paper. Old owner's name on t-p. (M. Harboe). Woodcut title-pages and vignettes. First edition of Lessing's first collection of "Lustspiele", containing the first printing of "Minna von Barnhelm".Lessing (1729-1781) is the most important literary writer of the Age of German Enlightenment; with him this period is fulfilled as well as overcome."Minna von Barnhelm" is one of Lessing's most important and successfull works and is considered one of the absolute best of his plays. "Es war die erste deutsche Dramatische Dichtung, welche nicht gemacht, sondern erlebt war." (Hettner, Geschichte der deutschen Literatur im 18. Jahrh., II: 310). Lessing himself wrote in a letter that should "Minna of Barnhelm" not turn out to be the very best of his plays, he would be very disappointed, and never have anything to do with the theatre again. " "Minna von Barnhelm" ist unbedingt die vollendeste dichterische Leistung Lessings." (Hettner, II: 310). Goethe also considered this work a masterpiece; he found it the most sincere thing to have come out of the Seven Years War and a work of immense importance and impact. With this work we find the genres of drama and comedy fulfilled."Nach ein paar Wanderjahren kehrte er nach Berlin zurück, wo 1766 un 1767 zwei seiner Meisterwerke erschienen: der "Laokoon" und das Lustspiel "Minna von Barnhelm".

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.

Paris, Estienne Michallet, 1688. Cont. full calf. 5 raised bands on back, back richly gilt, all edges of boards gilt. Lacking leather at capitals, front-hinge cracked, so cords are showing. Second or third printing of the original edition. The title-page states "seconde edition", but it is probably the third, printed in the same year as the first and second, being a page-by-page re-impression of the second, except for the fact that corrections have been made and the errata-leaf is thus not printed in the third. Both the second and third original editions are from the same year and by the same printer as the first. "La seconde édition, également impr. en 1688 n'offre que quelques légers changements..., et la troisième, sous la même date, ne qu'une simple réimpression de la seconde." (Brunet III:720). This work includes the first French translation of Theophrast's Characters (and probably the first translation into any modern language?). "Theophraste a eu le grand honneur, comme on sait, d'être ttraduit au XVIIe siècle par La Bruyère: et c'est pourquoi, en France plus que dans tout autre pays, en dehors même du cercle des érudits, son nom et son opuscule sont populaires." (navarre, Budé-edition of "Caractères", Paris, 1920).Jean de la Bruyère (1639/1644 - 1996) was a very famous French moralist and writer. "C'est au commencement de 1688 que parut la premiere édition des "Caractères de Théophraste traduits du grec, ou les Mæurs de ce siècle." L'auteur mettait ses propres observations sur la société moderne sous le patronage d'un ancien." (N.B.G. p. 427). The "Characters" gave La Bruyère quite a few enemies and created furor in the learned world. In Denmark Holberg calls him "trivial and simple" (Epistle 404). "Mais si en effet la malignité contemporaine, applaudissant aux traits satiriques de l'ouvrage, a peu contribuer à sa vogue, le jugement de la postérité l'a consacré comme un des meilleurs livres de notre langue." (N.B.G. p. 427). This work is thus still considered to be one of the greatest French books. Voltaire writes in "Siecle de Louis XIV, c. XXXII": "On peut compter parmi les productions d'un genre unique les "Caractères" de La Bruyère. Un style rigide, concis, nerveaux, des expressions pittoresques, un usage tout nouveau de la langue, mais qui n'en bless pas les règles, frappèrent le public". Bruyère's work with the translation really did cause astonishment and had an immense impact on late 17th century Europe and onwards; it created a new literary genre in Europe, and the age of Enlightenment was delighted with the short, precise characterizations of people and their customs. For an analysis of the contents and the impact on the time of La Bruyère see Nouvelle Biographie Generelle (N.B.G. pp. 426-39). Brunet V:798 + III:721, Graesse 4:61.

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...

With the rare original dust-jacket, in excellent condition, w. a tear to upper front hinge, no loss, and a few other small nicks and tears w. almost no loss. Some underlinings and marginalia in pencil. XV, (1), 294 pp. First edition, presentation-copy, of Quine's main work, in which he introduces the notorious indeterminacy of translation thesis. This is the most philosophical of all of Quine's works, and it has greatly affected the development of logic, philosophy of language and mathematics, and analytic philosophy in general.The presentation-inscription to front free end-paper reads as thus: "To Rod Firth/ with best regards./ Van". Roderick Firth was Quine's colleague as professor of philosophy at Harvard. He was chairman of the philosophy department at Harvard from 1957 until 1963. He earned a doctorate at Harvard in 1943, joined the faculty in 1953 and became Alford Professor of Natural Religion, Moral Philosophy and Civil Polity in 1962.It is in his "Word and Object" that Quine propounds his "indeterminacy of translation"-thesis, which became central in the development of philosophy of language. "Language is a social art. In acquiring it we have to depend on intersubjectively available cues such as to what to say and when. Hence there is no justification for collating linguistic meanings, unless in terms of men's dispositions to respond overtly to socially observable stimulations." (Preface p. IX).Quine bases his main thesis on his consideration of the linguist, who attempts to translate a hitherto unknown language. There are different methods that the linguist could apply as to the breaking down of sentences and distribution of function among the words. Quine reaches the conclusion that if any hypothesis of translation needs to be defended, this can only be by appeal to context, by determining what other sentences the language user would utter in the language that is unknown to the linguist. But even here the indeterminacy of translation sets in, because, according to Quine, any hypothesis can be defended, if only enough other hypotheses of other parts of the language are adopted. This indeterminacy of language also applies to the known languages, and even one's own, and thus Quine implies that there are no such entities as "meanings" of right and wrong. Quine thus denies any absolute standards in translating one language into another, but he admits that there are good and bad translation, -this is just not philosophically or logically relevant. Translation can be inconsistent with behavioral evidence, however and thus Quine propounds his pragmatic view of translation. "Neurath has likened science to a boat, which, if we are to rebuild it, we must rebuild plank by plank while staying afloat in it. The philosopher and the scientist are in the same boat. If we improve our understanding of ordinary talk of physical things, it will not be by reducing that talk to a more familiar idiom; there is none. It will be by clarifying the connections, causal or otherwise, between ordinary talk of physical things and various further matters which in turn we grasp with the help of ordinary talk of physical things." (P. 3 - § 9).

Hittorf's papers pp. 177-211 (Bd. 89), pp. 1-33 (Bd.98), pp. 1-56 (Bd.103), pp.337-411 a. 513-586 (Bd. 106). In all 7 engraved plates. All issues fine and clean. First printing of all 4 fundamental papers on electrochemistry, where Hittorf states his concepts of ionic migration and transport numbers, concepts that should be the foundation stones of the later evolved theory of ionization, culminating in Svante Arrhenius's famous discovery of electrolytic dissociation."After Faraday's experimental investigations in 1834, it was accepted that the electricity passing through an electrolytic cell was carried by the movement of charged ions produced from the decomposition of the compounds making up the solution. Daniell had extended these ideas in 1839 and showed that salts were compounds not of acid anhydrides and metallic oxides as had been thought, but of metallic cations and elemental or compound acid anions. Believing that the conductivity of solutions was due to these ions, he began a study of their transference. In 1853 Hittorf took up the problem. He extended the ideas of Daneill by reasoning inthe following manner: Cations and anions exist in solutions and migrate under the influence of current through the solution. The migration of the cation toward the cathode and away from the anode, and the deposition of the anode on the positive electrode, together result in a decrease of teh salt in the neighborhood of the anode. A similar analysis shows that there is also a decrease in the concemtration of the salt in the neighborhood of the cathode. If the motion of the two dissimilar ions were the same, the decrease in the concentration of the salt would be the same at the two electrodes.....Hwe concluded that the speeds of migration...were different and he characterized this fact by defining "transport numbers", which specified the portion of the transport of electricity carried by each ion. (DSB VI, p. 439). - Leicester & Klickstein "A Source Book of Chemistry", p. 400-406.In the 2 issues of 1853 are contained 2 papers by Helmholtz of fundamental cjharacter, both in physiology and on the theory on the conservation of energy.

(Bd. 89 No.6 a. 7). Pp. 211-233 a. pp. 353-377."In this work (the papers offered) Helmholtz for the first time enters the field of mathematical physics and physiology, with the full equipment of the higher mathematical analysis, of which he was the only master in its application to the latter science.....This very interesting and fundamental work on the distribution of electrical currents in material conductors is purely mathematical in character, owing to Helmholtz's method of proving the theorems, which are intelligible enough from the physical point of view, It is essentially connected with the treatise on the CONSERVATION OF ENERGY, since helmholtz merely substitutes for the expression 'free tension' there employed, the identical concept of Gauss's potentia, or Green's potential function."(Koenigsberger in "Hermann von helmholtz", p. 99-103.).

London, Macmillan & Co, 1908. Royal8vo. Bound in publisher's pictorial cloth. Gilt lettering and Nature's logo to spines and front board. In "Nature", May - October, 1908, Vol. LXXVIII [78]. Entire volumes offered. "Emmanuel College" in gilt lettering to spines. Two library stamps to title-page and first index page. A small tear to top of spine and signs after removal of label to spine. 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.
