Braun's paper: pp. 552-559 a. 6 textillustrations showing the Braun tube and its operations. Clean and fine. <br/><br/><em>First printing of this groundbreaking paper being the first description of the principles governing the "BRAUN TUBE" which moves the elctron beams of alternating voltage the principle on which ALL TELEVISON TUBES operate. - Braun shared the Nobel Prize for 1909 with Marconi "in recognition of their contributions to the development of wireless telegraphy"."Cold cathode tube with side anode annular diaphragm to control spot size and built-in fluorescent screen. Beam deflection by one external coil with the trace viewed indirectly in a rotating mirror or by two coils at right angles for direct viewing. Excitation by hand-drive influence machine friction generator or by an induction coil. This "indicator tube" which enabled Braun to demonstrate how a variety of periodic and transient electrical phenomena could be visually examined is the ancestor of electric oscilloscopes televison picture tubes and other electron-beam display devices." Shiers & Shiers "Early Televison. A Bibliography to 1940" No. 263."The first oscilloscope or Braun tube was introduced in 1897. In order to study high-frequency alternating currents Braun used the alternating voltageto move the electron beam within the cathode tube. The trace on the face of the cathode tube represented the amplitude and frequency of the alternating-current voltage. He then produced a graph of this trace by use of a rotating mirror. The Braun tube was a valuable laboratory instrument and modifications of it are a basic devise in electronic testing and research. The principle of the Braun tube moving a electron beam by means of alternating voltage is the principle on which all televison operate."DSB II pp. 427-428.In 1909 he shared the Nobel Prize for physics with Guglielmo Marconi for their development of wireless telegraphy. </em> unknown
185143324Leipzig Johann Ambrosius Barth 1851. Without wrappers as issued in "Annalen der Physik und Chemie. Hrsg.von Poggendorff" Bd. 83 Viertes Stück.= Heft No. 8 of 1851. The entire issue offered Heft 2 of vol. 83 with titlepage to vol. 83. Pp.469-600 a. 2 engraved plates. Helmholtz's paper: pp. 505-540. Clean and fine. <br/><br/><em>First appearance of this paper in which Helmholtz for the first time measures and gives the mathematical formula for the duration of induced electrical currents and thus distinguished with mathematical accuracy from those due to nerve-action."In the offered paper he begins by stating a mathematical law which he had verified by a long and difficult series of experiments. By means of this law F. neumann was enabled to solve the problem he had previously laid aside as to the distribution of current in a copper disk rotating below the two poles of a magnet.After Helmholtz had extended this exponiential law mathematically to divided circuits he tested it experimentally by means of a new type of galvanic contact-key which madeit possible to vary the interval between the opening and closing of any current as required."Koenigsberger "Hermann von helmholtz" pp. 79-80. </em> unknown

Kirchhoff's paper: pp. 193-217. With titlepage to volume 100. <br/><br/><em>First printing of an importent papers on the theory of electricity in conductors telegraph-cables etc. determining the velocity of the electrical propagation. He found that the propagation velocity of electricity to be "very close to the velocity of light in empty space"."The work of Thomson on signalling along cables was followed in 1857 the paper offered by a celebrated investigation by Kirchhoff's on the propagation of electrical disturbance along a telegraph wire of circular cross-section. 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 </em> unknown

Very light browning to 2. Abhandlung. <br/><br/><em>First appearance in German of Volta's importent paper in which he describes the electrical forces that acts between the metal-plates in the Voltaic Pile. The German publication was printed in the same year as the Italian original "Sull' identita del Fluido Elettrico col Fluide Galvanico" 1802."A long memoir by Volta in two parts.reports that by measuring the electrometer deflections with different pairs of metals he found that the forces which drive the electric fluid.from the first metal to the second are: silver/copper 1 copper/iron 2 iron/thin 3 lead/tin 1 lead/zinc 5. Then the force for silver/zinc in immidiate contact is 12 12315 copper/tin 5 = 32 iron/zinc 9 513 etc. Thus 'the force or impulsion with which two metals act on the electric fluid is equal to the sum of the forces of the series of metals which stands between them and.the electric force is the same as that which arises when the two extreme metals have no effect on the force of the latter'. This is the first statement of what Maxwell called 'Volta'slaw of contact electricity'."Partington IV p.15. </em> unknown
