Paris, Imprimerie Royale, 1735. 4to. Fine recent marbled boards. Printed titlelabel on frontcover. (6),144 pp. and 1 double-page folded engraved plate. Johann B's paper: pp. (1-) 91. - Daniel B's papers: pp. (93-) 122 and pp. 123-144. A few marginal brownspots.
First edition of these prize winning papers by father (Jean) and son (Daniel). - Both papers deals with the cause of the inclination of the planetary orbits relative to the solar equator. - In Daniel's paper he put foreward the hypothesis of the existence of an atmosphere, resempling air, and rotating around the solar axis, resulting in an increasing inclination of the planetary orbits toward the equator of the sun. Daniel was the first importent Newtonian outside Great Britain. The problems faced here (by Daniel) are treated in Newtonian manner.The publication of these papers by father and son resulted in a controversy between the two, forcing Daniel to leave his fathers house. - Poggendorff I:161.
Méthode pour trouver les Tautochrones, dans des Milieux résistants, comme le Quarré des Vitesses.
(Paris, L'Imprimerie Royale, 1732). 4to. Without wrappers. Extracted from ""Mémoires de l'Academie des Sciences. Année 1730"". Pp. 78-101.
First printing of Johann Bernoulli's importent paper in which he for the first time (Euler did it at the same time) solved the problem of finding the tautochrone in a medium that resists a body's motion directly as the square of the body's speed.After Huygens first discovered that the cylcoid was a tautochronous curve in vacuo according to the hypothesis of uniform gravity" Newton and Hermann have also given tautochrones following the hypothesis of non-uniform gravity acting, and pulling towards some fixed point as centre. Moreover, they have considered the motion to arise in a vacuum, with no resistance. Truly pertaining to resisting media, Newton has also shown that the cycloid is a tautochrone in a medium for which the resistance is proportional tothe speed moreover, as far as any other kinds resisting media are concerned, there has been no progress made either in roducing the curves themselves or in demonstrating possible tautochronism in them [The 3rd edition of the Principia that Euler refers to finally in 35 alters this view to include the type of resistance offered here. It may be of interest to the reader to observe that Johan. Bernoulli published a paper in the Memoire de l'Acad. Roy. des Sciences in 1730, also present in his Opera Omnia, T. III, p.173, with the title (in tra. from French): Method for Finding Tautochrones in Media Resisting as the Square of the Speed in which Euler does not get a mention.].

Quantal phase factors accompanying adiabatic changes.
London, Royal Society, 1984. Royal8vo. Full buckram, gilt lettering to spine.In: ""Proceedings of the Royal Society of London"", Series A, vol. 392. IV,478 pp. (Entire volume offered). Berry's paper: pp. 45-57. Clean and fine.
First printing of the paper in which Berry describes his discovery of the ""Berry phase"", a unifying concept in quantum mechanics.""In 1983, Berry made the surprising discovery that a quantum system adiabatically transported round a closed circuit in the space of external parameters acquires, besides the familiar dynamical phase, a non-integrable phase depending only on the geometry of the circuit. This Berry phase, which had been overlooked for more than half a century, provides us a very deep insight on the geometric structure of quantum mechanics and gives rise to various observable effects. The concept of the Berry phase has now become a central unifying concept in quantum mechanics, with applications in fields ranging from chemistry to condensed matter physics. In particular, the Berry phase plays an important role in modern magnetism, an allows to reach a deeper understanding of a broad range of phenomena such as the spin-orbit coupling, the Aharonov-Bohm effect, the quantum Hall effect, the anomalous Hall effect, the magnon dynamics, the tunneling of magnetization in molecular magnets, etc. Further, in the light of the Berry phase, a number of new phenomena can be predicted in ferromagnets with a textured magnetization or in semiconductors with spin-orbit coupling.""

Silver-Stained Roundels and Unipartite Panels before the French Revolution Flanders, Vol. 2: The Provinces of East and West Flanders
, Brepols Publishers, 2011 Hardcover, XIV 631 pages., 300 b/w ill. 900 colour ill., 230 x 315 mm, English. ISBN 9781905375318.
This checklist is the second in a series of volumes describing the silver-stained glass roundels and unipartite panels from the Middle Ages to the 18th century found in public buildings, museums and private collections in the present five provinces of Flanders (Belgium). It also includes documented roundels and unipartite panels whose whereabouts are presently unknown and those which have been removed to other locations or collections in the past. The checklist also mentions all known related material. Where possible, photographs of this material have been added. As far as the related material is concerned, the relevant publications are also mentioned. This material includes models, drawings, engravings, and roundels which belong either to the same series or to those which are copies of these series. The present volume covers the Provinces of East and West Flanders (more or less the former County of Flanders). The first checklist, concerning the Province of Antwerp, was published in 2007. Additional volumes for the Provinces of Flemish Brabant and Limburg (Vol. 3), and the one with Addenda (Vol. 4) are in the planning stage. The former County of Flanders, with the cities of Bruges and Ghent, must once have displayed huge quantities of stained glass, which for the most part have been lost or relocated. The causes and reasons for this loss include natural calamities, fires, deliberate destruction and neglect. Most of the surviving roundels are now in foreign collections: on the continent; in Great Britain; or in the United States of America. It is worthy of note that great efforts have been made in the USA and Great Britain to compile and publish checklists of silver-stained roundels and other small panels, originating from the Low Countries, whilst here, where they were produced, this series is the first genuine overview that has ever been published. During the 15th and 16th centuries roundels and small panels played an important role as 'public relations' gifts among the upper classes, the church and its associated religious orders. As these gifts played a very significant role in social life, demand for these items was very high. It is clear that the manufacture of roundels and small panels was a substantial part of the earnings of these glass workshops, which also produced monumental windows. The most popular themes were predominantly religious, but also included heraldic, secular, mythological and allegorical subjects. The seasons and months and labours of the year were also commonly found. In the late 16th and the 17th centuries the range of iconographical subjects became more secular with, among other themes, representations of professions. Heraldry also remained very important, and in the second half of the 17th and the beginning of the 18th centuries nearly all roundels and panels depicted armorials and included the name of their donors.

First appearance of this collection of Berthelot's famous memoirs on thermochemistry to which he turned his attention in 1865. In these lectures he introduced the concepts of 'exothermix' and 'endothermic'. He also intorduce his famous 3 principles - equivalence between internal and heat changes in chemical reactions, heat evolved or absorbed in a chemical change depends onlyon the initial and final states of the reactans and products, provided no external work is done, and ""law of maximum work"" which says that ""every chemical change accomplished without the intervention of energy from outside tends towards the production of a body or system of bodies which produce the most heat"". The principles of Thermochemistry given here Berthelot considered himself fundamental.""In the 1860s Berthelot was done with synthesis and turned to thermochemistry, the study of the heat of chemical reactions. In some of his work he had unknowingly been anticipated by Hess, but he went much further. He devised a calorimeter within which he could measure the heat of chemical reactions and ran hundreds of determinations. This work along with that being conducted by Thomson threw the science of thermochemistry into high gear.""(Asimov).

Together with the memoir printed at the same time in ""Mémoires de l'Institut.."" this is the first appearance of B's groundbreaking work on the nature of chemical affinity and the fact that many factors influence chemical reactions, comparing chemical affinity to the force of gravity. The paper was at the end of the year published separately.The theory set forth here ""led directly to Prout's investigations which yielded a knowledge of definite chemical proportions and thus played a very importent part in preparing the way for the development of the Atomic Theory on which the whole modern chemistry is based.""(Duveen, p. 75).""Berthollet read a memoir on the general theory of affinities while he was still in Egypt. This was the starting point of his complete new system of chemistry, first briefly sketched in Recherches sur les lois de l’affinité (1801) and later developed into the comprehensive, two volume Essai de statique chimique. Here he attempted to provide a proper basis for chemistry, so that its experimental results could be viewed in the light of theoretical first principles. Berthollet developed a theory and a model adequate for the understanding and the interpretation of the rapidly growing body of chemical knowledge in his time. He was aware that the positive work of constructing a new theory had yet to be performed after the shock of Lavoisier’s criticism of the old chemistry.(DSB).Parkinson ""Breakthroughs"", 1801 C.

In 1829, Jöns Jakob Berzelius of the Royal Karolinska Institute, Stockholm extracted thorium from a rock specimen sent to him by an amateur mineralogist who had discovered it near Brevig and realised that it had not previously been reported. The mineral turned out to be thorium silicate, and it is now known as thorite. Berzelius even produced a sample of metallic thorium by heating thorium fluoride with potassium, and confirmed it as a new metal. He called the black mineral thorite, in honor of the Scandinavian god Thor.Parkinson ""Breakthroughs"", 1829 C.

First edition of this milestone work in astronomical obeservation, where Bessel reduced the observations for the ""personal equation"" based on Bradley's observations and here published Bradley's Greenwich observations for the first time and making a catalogue of 3222 stars extracted from them.""The positions of Bradley’s stars valid for 1755 were published by Bessel as Fundamenta astronomiae pro anno 1755 (1818). This work also gives the proper motions of the stars, as derived from these observations of Bradley, of Piazzi, and of Bessel himself. It constitutes a milestone in the history of astronomical observations, for until then positions of stars could not be given with comparable accuracy: through Bessel’s work, Bradley’s observations were made to mark the beginning of modern astrometry. During this investigation Bessel became an admirer of the art of observation as practiced by Bradley"" and because Bradley could not evaluate his own observations, Bessel followed and also taught the principle that immediately after an observation, the reduction had to be done by the observer himself. Further, he realized that the accurate determination of the motions of the planets and the stars required continuous observations of their positions until such motions could be used to predict ""the positions of the stars .... for all times with sufficient accuracy.""

First appearance of a milestone paper in astronomy, giving the solution of the great problem of distances in the universe which had baffled astronomers ever since the time of Copernicus, announcing the FIRST SUCCESSFUL DISPLACEMENT OR PARALLAX OF A FIXED STAR and hence deducing the FIRST RELIABLE DISTANCE OF THE EARTH TO A FIXED STAR. The parallax observed corresponded to ab. 600.000 times that of the earth from the sun. On these grounds Bessel calculated the distance to about 11 light years, and this was confirmed by fresh investigations by Bessel in 1839-40 (the second paper offered). In 1842-43 it was also confirmed by C.A.F. Peters at Pulkowa. It is the first published instance of the fathom-line thrown into celestial space.Bessel communicated his observations in Comptes Rendus, in a letter to Humboldt (the offered paper dated Nov. 5, 1838), in ""Monthly Notices"" in letter to J. Herschel, and in ""Astronomische Nachrichten"" Vol. 16, No 365-66 (pp. 65-96), 1838), where a more detail account was published.Ther paper ""Bestimmung der Entfernung des 61sten Stern des Schwans"" in ""Astronomische Nachrichten"" is dated at the end: Altona 1838, Dec. 13.Bessel's investigation was hailed by John Herschel when Bessel was awarded the R.A.S. gold medal ""The greatest and most glorious triumph which practical astronomy has ever witnessed"". ""For determining the parallax of 61 Cygni, Bessel selected two comparison stars of magnitude 9-10 at distances of roughly eight and twelve minutes of arc. 61 Cygni is a physical double star whose components differ in brightness by less than one magnitude. The distance of sixteen seconds of arc between the components favored the accuracy of the determination of the parallax because pointing could be carried out with two star images. After observing for eighteen months, by the fall of 1838 Bessel had enough measurements for the determination of a reliable parallax. He found that p = 0.314? with a mean error of ±:0.020?. This work was published in the Astronomische Nachrichten (1838), the first time the distance of a star became known. Bessel’s value for the parallax shows excellent agreement with the results obtained by extensive modern photographical parallax determinations,...""
