Series: II [of IV]. 8vo. viii, 272 pp. Frontis. port., 21 figs. Later half gilt-stamped black cloth, gray boards. Bookplate of Nicholas Chako. Near fine. This is the second volume [Band 2] in the series, with all the titles being: Band 1: Vorlesungen uber Mechanik (464 S.) / hrsg. von W. Wien. Band 2: Vorlesungen uber mathematische Optik. Band 3: Vorlesungen uber Electricitat und Magnetismus. Band 4: Vorlesungen uber Theorie der Warme. "In a period of expanding scientific knowledge, the need soon arises for ordering and logical analysis of new knowledge. Among the leading physicists of the nineteenth century, it was Kirchhoff whose temperament was best suited to this task. In all his work he strove for clarity and rigor in the quantitative statement of experience, using a direct and straightforward approach and simple ideas. His mode of thinking is as conspicuous in his contributions of immediate practical value (the laws of electrical networks) as in those with wide implications (the method of spectral analysis). The excellence of Kirchhoff as a teacher can be inferred from the printed text of his lectures (he managed to publish only those on mechanics, the others being edited posthumously)." â" DSB VII, p. 382.

Akad. Wiss. Berlin, 1876. - Berlin 1877, 4°, pp.75-84, Broschur. Erstdruck! Gustav Robert Kirchhoff (1824-1887) Physiker, der sich insbesondere um die Erforschung der Elektrizität verdient gemacht hat.

8°. X, 636 S. mit 5 gefalt. Kupfertafeln. Pbd. d. Zt. mit handschr. Rückenschild. DSB 7, 379. Poggendorff I, 1260. - Erste Ausgabe seiner ersten Veröffentlichung und zugleich eine seiner wichtigsten. Er beschreibt hier die Gesetze der elektrischen Stromverzweigung, die später als "Kirchhoffsche Regeln" bezeichnet wurden. - "The excellence of Kirchhoff as a teacher can be inferred from the printed text of his lectures (he managed to publish only those on mechanics, the others being edited posthumously). They set a standard for the teaching of classical theoretical physics in German universities, at a time when they were taking a leading position in the development of science" (DSB). - G. R. Kirchhoff (1824-1887), Professor in Breslau, Heidelberg und Berlin, begründete mit Bunsen die Spektralanalyse und stellte das nach ihm benannte Gesetz über Emission und Absorption von Licht sowie die Regeln über die Verteilung elektrischer Ströme auf. - Einband etwas berieben, St.a.T., etwas gebräunt, die Tafeln teils wasserrandig, sonst gut erhalten. Sprache: deutsch.

(Leipzig, Johann Ambrosius Barth, 1858). Without wrappers. In "Annalen der Physik und Chemie. Hrsg. von J.C. Poggendorff", Bd. 103, No 2. Pp. 177-352 a. 1 folded engraved plate. (Entire issue offered). Kirchhoff's papers: pp. 177-206 a. pp. 206-209. First appearance of this importent paper on the mechanical equivalent of heat in which Kirchhoff showed that the variation of the heat of a chemical reaction is given by the difference in heat capacity between products and reactants in an equation. Integration of his equation permits the evaluation of the heat of reaction at one temperature from measurements at another temperature.Kirchhoff's Law describes the enthalpy of a reaction's variation with temperature changes. In general, enthalpy of any substance increases with temperature, which means both the products and the reactants' enthalpies increase. The overall enthalpy of the reaction will change if the increase in the enthalpy of products and reactants is different.

(Entire issue offered). Kirchhoff's paper: pp. 529-545. Clean and fine. Firs appearance of Kirchhoff's first paper on conductivity in which he presents his Circuit-Law. The significance of this paper is that Kirchhoff proved with action at a distance that electric disturbances travel along wires of neglible resistance with the velocity of light. He accomplished this with the laws of Newtonian electrodynamics before Maxwell formulated his equations."The theory of variable currents raised more difficult problems. The law of dynamical interactions between currents had been formulated by Ampere (1826) in the spirit of the concept of action at a distance.The field was still open when Kirchhoff entered it in 1857 with his own general theory of the motion of electricity in conductors (in the paper offered). 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 Weber and Kirchhoff however, pointing to the extreme character of the condition of infinite conductivity, dismissed this result as a mere accidental coincidence."(DSB VII, p. 380-81).

1 3/4 pp. gr.-8vo°. Nadelspuren am linken Rand. An ein Mitglied der Museumsgesellschaft in Frankfurt a.M., dessen Wunsch nach einemVortrag er nicht erfüllen könne.". Die Zeit, in der ich einmal die Ehre hatte, das zu thun, steht mir noch in der angenehmsten Erinnerung; dennoch muß ich . mich außer Stande erklären, Ihrer ufforderung nachzukommen. Mit meinem Fußübel geht es sehr viel besser, als in den früheren Jahren, dennoch behindert mich dasselbe noch in empfindlicher Weise bei jeder ungewöhnlichen Unternehmung und hält mich in der Furcht, daß wieder ein ernstlicher Rückfall einritt .".

M. und die Uebersendung der Mittheilung des Hrn. Otto v. Littrow, die mich in hohem Grade interessirt. Gestatten Sie mir, Ihnen meinen herzlichsten Dank für dieses Wohlwollen auszusprechen [.]".

Paris, Victor Masson et Fils, 1861. Without wrappers. In: "Annales de Chimie et de Physique", 3e Series - Tome 62, Cahier Juin 1861. Titlepage to vol. 62. Pp. 129-256. (The entire issue offered). Kirchhoff's paper: pp. 160-192. Small stamps to verso oftitlepage. First French edition of a milestone paper by "The Grandfather of Quantum Theory" in which he formulates the law named after him, "KIRCHHOFF'S LAW", which was the "key to the whole thermodynamics of radiation. In the hands of Planck, Kirchhoff's successor to the Berlin chair, it proved to be the key to the new world of the quanta, well beyond Kirchhoff's conceptual horizon."(DSB, VII, p.382)."Kirchhoff's Law of Thermal Emission was formulated in 1859 (Über das Verhältnis.) - the paper offered here in the first French version. It is at the same time the simplest and least understood law in physics. Kirchhoff's law states that given thermal equilibrium with an enclosure, the radiation inside will be always black, or normal, in a manner which is independent of the nature of the walls, or the objects they contain. This is known as the concept of universality. That is, that radiation within an enclosure can always be described by a universal function dependent only ontemperature and frequency. This universal function was first given us by Max Planck, in 1900. Kirchhoff's law STANDS AT THE HEARTH OF ALL MODERN ASTROPHYSICS. It is the basis for setting the temperature of the stars, for the gaseous model of the Sun, and for believing that we now know the temperature of the entire universe."(Pierre-Marie Robitaille).The research background for the paper was his unexpected observation that if the intensity of the solar spectrum increased above a certain limit, the dark D lines were made much darker by the interposition of the sodium flame. he instantly felt, that he had got hold of "something fundamental". Another notable, and importent paper in the development of photography, is in the same issue ALPHONSE POITEVIN "De l'Action chimique de la Lumiere sur les Substances organiques. Son emploi à l'impression photographique."Pp. 192-210.
