Some browning as usual. With titlepage to the volume 1683. Titlepage with a stamp and a faint dampstain. First edition of Tschirnhaus' "Tschirnhaus Tranformation".Tschirnhaus work intensively on finding a general method for solving equations of higher of higher degree. "His transformations constituted the most promising contribution to the solution of equations during the seventeenth century; but his elimination of the second and third coefficients by means of such transformation was far from adequate for the solution of the quintic.(Boyer. A History of Mathematics, 1968, 472 p.).Tschirnhaus (1651-1708) , a Saxon nobleman, had as wide interest as acquaintances: He studied in Leyden, served in the Dutch army, visited England and Paris several times. He set up a glassworks in Italy and is said to have introduced Porcelain to Europe. He wrote about philosophy and mathematics and was a close friend of Leibniz."In mathematics, a Tschirnhaus transformation, also known as Tschirnhausen transformation, is a type of mapping on polynomials developed by Ehrenfried Walther von Tschirnhaus in 1683. It may be defined conveniently by means of field theory, as the transformation on minimal polynomials implied by a different choice of primitive element. This is the most general transformation of an irreducible polynomial that takes a root to some rational function applied to that root."(Wikipedia).Parkinson "Breakthroughs 1683 M.

Previous owner's name (Julius Christian Vilhelm Schousboe) in contemporary hand to title-page. First and last leaves brownspotted. 48, LXXIV (tables) pp. + 1 large folded map. First edition of this pioneer-work in oceanography and hydrography, as it is the first scientific investigation in this field of research. "Forchhammer's fundamental researches on the composition of seawater brought him international acclaim. He began this work in 1843, more as a geologist than as a chemist, to explain the phenomena that give rise to the deposits on the sea floor...He carried out analyses of over 160 samples collected for him over a twenty-year period by the Danish and British navies." (DSB V: p. 72). The work was translated into English as "On the Components of Sea Water" (1865) in Phil. Transactions.

London, Printed by Taylor and Francis - Published by the Author, (1862-) 73. Folio. Papersize 54,5x36,5 cm. Lithographed and fully handcoloured. Two birds, male and female on branches with fruits. J. Gould & H.C. Richter, del. et lith. - Walter, Imp. Fine and clean. The plate is accompanied with the original textleaf. (2) pp. This is an original plate from Goulds great work "The Birds of Great Britain", issued between 1862 and 1873. The plates in this work were executed by Gould himself, and a few by J. Wolf, H.C. Richer and Hart. Together with Audubon's plates, the Gould-plates are considered the best bird-art ever produced, AND THE PLATES IN HIS "BIRDS OF GREAT BRITAIN" ARE THE PEAK OF GOULD'S ARTISTIC LIFE. In the foreword Gould stresses the difference from his "Birds of Europe" in the treatment of the illustrations, the inclusion here of the figures of the baby birds and nests, and he comments "Many of the public are quite unaware how the colouring of these large plates is accomplished; and not a few believe that they are produced by some mechanical process or by chromo-lithography. This, however is not the case; every sky with its varied tints and every feather of each bird were coloured by hand; and when it is considered that nearly two hundred and eighty thousand illustrations in the present work have been so treated, it will most likely cause some astonishment to those who give the subject a thought.". Elsewhere he remarked upon employing "almost all colourists in London." - Wood p. 364. - Nissen No. 372. - Sitwell 102. - Zimmer pp. 261-62. - Not in Jean Anker.

(Leipzig, Johann Ambrosius Barth, 1906). No wrappers. Extracted from "Annalen der Physik" Vierte Folge. Bd. 20. Pp. 199-206. Clean and fine. First printing of one of the papers for which Einstein was awarded the Nobel Prize in 1921. It was for the papers "Ueber einen die Erzeugung und Verwandlung des Lichtes betreffenden heuristischen Gesichtspunkt" of 1905 and "Zur Theorie der Lichterzeugung...( Theory of light emission and absorption), the offered item, that Einstein received the prize: "for his services to theoretical physics and especially for his discoveryof the law of the photoelectrical effect" - his reward was not based on relativity."The quantum theory has affected virtually every branch of physics. Its earliest and one of its most significant developments was Einstein's application of the theory to what is known as the 'photo-electrical effect'....Einstein explained this effext by suggesting that the classical view that light is emitted in the form of continous waves must be abandoned. The photo-electrical effect could be explained only as an example of quantum action where the waves of light or X-rays are emitted in minute particles or bullets. It is he size of the bullet (the wave-lenght of the radiation) which determines the number of electrons ejected. It was for this, and not for the theory of relativity, that Einstein was awarded the Nobel Prize in 1921. Einstein's two fundamental papers on this subject are "Ueber einem Erzeugung...." 1905 and Zur Theorie der Lichterzeugung (the paper offered here)" (PMM the note to 391).Weil: 12 (with an asterix, denoting a major paper) - Boni:12.

Cologne, Jeremie Plantie, 1692. 12mo. In contemporary half calf over floral decorated wrappers. Small paper-label pasted on to top of spine. Wear to extremities. Title-page with underlinings in red. Intgernally nice and clean. 192 pp. + 1 engraved portrait. Uncommon first edition of this account of the romantic entanglements and military exploits of Charles Louis I, Elector Palatine. The son of Frederick V, the "Winter King" of Bohemia, and Elizabeth Stuart, sister of Charles I, Charles Louis spent much of his early life in exile due to the Thirty Years' War and the English Civil War. His political career was eventful but he is best known for his controversial personal life including his divorce from Charlotte of Hesse-Kassel and his bigamous marriage to Marie Luise von Degenfeld. His daughter, Elizabeth Charlotte, married Philippe I, Duke of Orléans, the younger brother of Louis XIV. She later became known as the "Grandmother of Europe" since her descendants included Francis I and Marie Antoinette.

(Berlin, J.A. Barth, 1902). No wrappers. In "Annalen der Physik", Vierte Folge. Band 8, No 5. Pp. 1-232 a. 1 folded plate. (Entire issue offered, No. 5). Lenard's paper: pp. 149-198. The block is punched in inner margins after cords. Punching does not affects the text. Fine and clean. First printing of Lenard's famous paper in which he made the crucial discovery that the electron energy showed not the slightest dependence on the light intensity', a fact to be explained in 1905 by the existence of light-quanta by Einstein."In 1902 Lenard succeeded in discovering importent properties of the photoelectric effect. He found that as the intensity of the light increases the number of electrons set free rises, but their velocity remains unaffected: the velocity depends solely on the wavelenght. The interpretation of this relationship was provided in 1905 by Albert Einstein's hypothesis of light quanta. In 1905 Lenard received the Nobel Prize in physics for his cathode ray experiments; and in 1907 he succeede Quincke as professor and director of the physics and radiology laboratory at the University of Heidelberg...(The Laboratory was renamed the Philipp Lenard Laboratory in 1935)."(DSB VIII, p. 181). - Parkinson "Breakthroughs" 1902 P.

København (Copenhagen), Levin & Munksgaard, 1933. Orig. printed wrappers. Backstrip with 2 small nicks and frontcover a bit faded at margins. 65 pp. (Det Kgl. Danske Videnskabernes Selskab, Mathematisk-fysiske Meddelelser XII,8). First edition of this fundamental papers in the development of quantum field theory. The process of measuring electromagnetic fields involves the observation of charged test bodies in those fields. Therefore the theory of electrodynamics is an inseparable extension of mechanics. A quantum theory of fields thus inherits, in some form, the limitations of measurement which lie at the foundation of quantum mechanics. In 1931 Landau and Peierls published a critical analysis of the consequences of such limitations in a relativistic quantum theory of fields. Landau and Peierls came to the negative conclusion that in several cases, the concept of momentum was without physical meaning and quantities such as the strength of a field was un-measurable. In their famous paper from 1933 Bohr and Rosenfeld (the work offered) carefully reviewed the arguments of Landau and Peierls and showed, through the use of particular measuring arrangements, that a consistent quantum theory of fields is possible without further limitations than the ones which secure the consistency of quantum mechanics. The BR-paper is often credited with having laid the foundation for quantum electrodynamics. Bohr continued his work in this field, and in 1937 he completed a manuscript entitled "Field and Charge Measurement in Quantum Theory", but this was never published. When, in the late 1940s the important work on QED by Tomonaga, Schwinger, Dyson, and Feynman appeared in The Physical Review, Bohr and Rosenfeld again joined and published the essentials of the 1937 manuscript in the same journal.See Abraham Pais: Bohr's Times, pp.358-364.

Kopenhagen, Jens Hostrup Schultz, (1835). 4to. 41 pp. Clean and fine. First printing of the second Danish decree to abolish the slave trade. Denmark was the first souvereign state in the world to abandon the slave trade by a decree issued in 1792. This did not mean, that the trade was hereby stopped. When France and England in 1831 and 1833 in conventions banned the trade, the Danish king Frederik VI issued this decree of 1835 to support these conventions. The decree of 1835 contains a detailed Criminal Law for transport of slaves over the Atlantic.The decree was issued in two forms at the same time, one with only Danish text and one with Danish and German paralelltext (the version offered).

First German edition of Mendeléev's doctoral dissertation "O soedineni spirta s vodoyu" from 1865. "In it he first developed the characteristic view that solutions are chemical compounds and that dissolving one substance into another is not to be distinguished from other forms of chemical combination. In this thesis, he also adhered to the principles of chemical atomism."(DSB). - This work contributed to the birth of a popular legend, which claims that Mendeleev invented the standard for Russian vodka, saying it should contain 40% of alcohol by volume. Mendeléev is credited as being the creator of the first version of the periodic table of elements. Using the table, he predicted the properties of elements yet to be discovered.The volume contains other notable papers by Kohlrausch, Fizeau, Zöllner etc. and Julius Thomsen's "Thermochemische Untersuchungen"

Cayley's paper: pp. 259-261 Fitrst appearance of Cayley's famous paper on the Four-Colour-Problem"The four-colour map problem (to prove that on any map only four colours are needed to separate countries) is celebrated in mathematics. It resisted the attempts of able mathematicians for over a century and when it was successfully proved in 1976 the ‘computer proof’ was controversial: it did not allow scrutiny in the conventional way. At the height of his influence in 1878, Arthur Cayley had drawn attention to the problem at a meeting of the London Mathematical Society and it was duly ‘announced’ in print. (the paper offered). He made a short contribution himself and he encouraged the young A. B. Kempe to publish a paper on the subject. Though ultimately unsuccessful, the work of Cayley and Kempe in the late 1870s brought valuable insights..... Francis Galton is revealed as the ‘go-between’ in suggesting Cayley publish his observations in Proceedings of the Royal Geographical Society." (Tony Crilly).The Four-Colour-Theorem was proved in 1976 by Kenneth Appel and Wolfgang Haken. It was the first major mathematical theorem to be proved using a computer.
