‎First edition in French of Kirchhoff's milestone papers on the interpretation of the dark D lines - noticed by Fraunhofer in 1814 - in the spectrum of the sun, the papers that inspired Max Planck to his theory of quanta (1900). The papers are the French translations of his papers published in Abhandl. d. königl. Akad. d. Wissenscchaften in Berlin in 1861 and 1862.In the course of his preparatory work in the autumn of 1859, Kirchhoff made an unexpected observation. It had long been known that the dark D lines, noticed in the solar spectrum by Fraunhofer (1814), coincided with the yellow lines emitted by flames containing sodium.....Kirchhoff's unexpected discovery was that if the intensity of the solar spectrum increased above a certain limit, the dark D lines were made much darker by the interrposition of the sodium flame. He instantly felt that he had got hold of ""something fundamental"", even though he was at a loss to suggest an explanation. On the day following the surprising observation, Kirchhoff found the the correct interpretation, which wass soon confirmed by new experiments: a substance capable of emittiing a certain spectral line has a strong absorptive power for the same line....The dark D lines in the solar spectrum could accordingly be ascribed to absorption by a solar atmosphere containing sodium. Immense prospects thus opened up of ascertaining the chemical composition of the sun and other stars from the study of their optical spectra. A few more weeks sufficed for Kirchhoff to elaborate a quantitative theory of the relationship between emissive and absorptive poweer.""(DSB VII, pp. 381-82).PMM, 278 b. - Barchas, 1169-70 - Sparrow, 117 - Horbli, 59 - Dibner, 153 (the note).‎

(Whittaker ""A History of the Theories of Aether and Electricity"", pp. 230 ff.).""The field was still open (the nature of the electric current) when Kirchhoff entered it in 1857 with his own general theory of the motion of electricity in conductors. His first paper, in which he treated linear conductors from the same premises as Weber, turned out to coincide in all essentials with an investigation carried out by Weber shortly before but delayed in publication. Both physicists noticed a remarkable implication of their theory: in a perfectly conducting circuit, oscillating currents could be propagated with a constant velocity, independent of the nature of the conductors, and numerically equal to the velocity of light. Both Kirchhoff and Weber, however, pointing to the extreme character of the condition of infinite conductivity, dismissed this result as a mere accidental coincidence.""(DSB)‎

‎Teaching and Impact of the 'Doctrinale' of Thomas Netter of Walden (c. 1374-1430) ,‎

‎Turnhout, Brepols, 2011 Hardback, XVI 298 p., 4 b/w tables, 156 x 234 mm. ISBN 9782503531793.‎

‎The first full-scale study of theologian Thomas Netter of Waldens Doctrinale, a work whose important response to the threat of Lollardy remained invaluable to later Counter-Reformation polemicists and apologists. Thomas Netter of Walden (c. 1374?1430) was a Carmelite friar, royal confessor, diplomat, religious superior, and theologian. His only extant theological work, the Doctrinale antiquitatum fidei catholicae ecclesiae contra Wiclevistas et Hussitas, was written with the purpose of combating the errors of Wyclif and his followers. For this reason, Netter's name and work are familiar mainly to those engaged in the study of Lollardy. Outside this field, Netter is almost unknown today, yet in his lifetime he was a highly regarded churchman who, it was said, could have had the pick of any diocese in England. From his death in 1430 until the middle of the eighteenth century Netter was a much-quoted and copied author whose exposition of Catholic teaching on subjects such as the Church, religious life, and the sacraments proved useful to many Counter-Reformation polemicists and apologists. This book is the first survey of the whole of the Doctrinale and it argues that there is more to Netter than anti-Lollard polemic. The author examines the principal topics in Netter's work : God, humanity, Christ, the Church, religious life, prayer, the sacraments ... and he makes the case that there is a definite plan which links the various parts of the Doctrinale into a whole giving it a certain theological unity.

‎This volume presents an interdisciplinary study of the triumphal entry of the Cardinal-Infante Ferdinand into Antwerp in 1635, and pays special attention to Rubens?s monumental arches and oil sketches that ornamented the entry. This volume deals with the triumphal entry of the Cardinal-Infante Ferdinand, brother of King Philip IV of Spain, into Antwerp in 1635, one of the largest and most spectacular festivals ever mounted in an early modern city. The outdoor festivities in honor of the city?s new governor included a citywide procession, performances, fireworks, music, and political speeches. Along the processional route appeared nine richly ornamented stages and arches designed by Peter Paul Rubens and executed by a group of local painters and sculptors, including Jacob Jordaens, Theodoor van Thulden, and Jan van den Hoecke. To commemorate the event, the city commissioned a lavish festival book, entitled the Pompa Introitus Ferdinandi (1641), which contains learned commentaries by Jan Gaspar Gevaerts, a city official and Latinist, as well as folio engravings by Theodoor van Thulden after Rubens's stages. More than a simple description of the event, Gevaerts? volume offers a rich compilation of references to ancient writers and reproductions of ancient coins.While most literature on the subject has focused on Rubens?s nine monumental arches and his twelve preparatory oil sketches for the designs, this volume will examine the entry and its accompanying festival book as a whole. A group of highly distinguished specialists from different disciplines will discuss the entry and Gevaerts? book from a myriad of viewpoints, including art, architecture, music, theater, history, politics, classical knowledge, and economic and intellectual networks. It is the first time that the entry will be examined from a truly interdisciplinary perspective. The book draws on a wide variety of primary sources, including Rubens?s preparatory oil sketches, Gevaerts? festival book, pamphlets describing the entry, and political songs from the period.

‎Nicodemus Tessin the Elder was an architect, gentleman, and founder of the artistic dynasty that was immensely influential at the Swedish court in the seventeenth and eighteenth centuries. He was architect to the crown, to the nobility, and to the city of Stockholm, and he supplied buildings for a wide range of functions, from palaces to banks, courthouses, and fortifications. His unusually extensive travels in the Netherlands, Italy, France and Germany provided him with a comprehensive picture of contemporary European architecture, which he drew on as he synthesized a new group of buildings that would attract international attention as models for princely architecture. His productivity required a new approach to architecture, and he was part of the first generation of architects in northern Europe to develop the architectural studio, distinguishing the design process from the business of building, and in the process recreating himself as the modern architect.

‎First printing of this importent paper in which Koenig set forth his ""Law of least Action"". The law states that the kinetic energy of a system of mass points is equal to the sum of the kinetic energy of the motion of the system relative to the center of gravity and of the kinetic energy of the total mass of the system considered as a whole, which moves as the center of gravity of the system.""While still in Franeker, Koenig wrote the draft of his important essay on the principle of least action, which was directed against Maupertuis. The controversy touched off by this work, which was published in March 1751, resulted in perhaps the ugliest of all the famous scientific disputes. Its principal figures were Koenig, Maupertuis, Euler, Frederick II, and Voltaire" and, as is well known, it left an unseemly stain on Euler’s otherwise untarnished escutcheon. The quarrel occupied Koenig’s last years almost completely" moreover, he had been ill for several years before it started. Koenig emerged the moral victor from this affair, in which all the great scientists of Europe—except Maupertuis and Euler—were on his side. The later finding of Kabitz2 testifies to Koenig’s irreproachable character.""(DSB).‎
