Experimental Researches in Electricity. - Fifteenth Series. § 23. Notice of the character and direction of the electric force of the Gymnotus. Sections 1749-1795. Received November 15 - Read December 6 1838.

183942286London Richard and John E. Taylor 1839. 4to. No wrappers as extracted from "Philosophical Transactions" 1839 - Part I. Pp. 1-12. 1 textillustr. Some discolouring to the 2 first leaves. First appearance of this paper in which Faraday finds by experimenting with a species of Gymnotus a group of electric fishes one was send to him by Humboldt proves that its electricity is of the same nature as all other kinds of electricity "The skock in very varied circumstances of position was procured: the galvanonmets affected magnets were made a wire was heated polar chemical decomposition was effected and the spark obtained."Abstract.From 1831 to 1852 Michael Faraday published his "Experimental Researches in Electricity" in The Philosophical Transactions of the Royal Society. These papers contain not only an impressive series of experimental discoveries but also a collection of heterodox theoretical concepts on the nature of these phenomena expressed in terms of lines of forces and fields. He published 30 papers in all under this general title.They represents Faraday's most importent work are classics in both chemistry and physics and are the experimental foundations for Maxwell's electro-magnetic theory of light using Faraday's concepts of lines of force or tubes of magnetic and electrical forces. His many experiments on the effects of electricity and magnetism presented in these papers lead to the fundamental discoveries of 'induced electricity' the Farday current the electronic state of matter the identity of electricity from different sources equivalents in electro-chemical decomposition electrostatic induction hydro-electricity diamagnetism relation of gravity to electricity atmospheric magnetism and many other."Among experimental philosophers Faraday holds by universal consent the foremost place. The memoirs in which his discoveries are enshrined will never ceaseto be read with admiration and delight; and future generations will preserve with an affection not less enduring the personal records and familiar letters which recall the memory of his humble and unselfish spirit."Edmund Whittaker in A History of the Theories of Aether and Electricity. unknown

BRAUN, FERDINAND - THE INVENTION OF THE CATHODE-RAY INDICATOR TUBE - SEEING BY ELECTRICITYBiblio.com

Ueber ein Verfahren zur Demonstration und zum Studium des zeitlichen Verlaufes variabler Ströme; On a Method for the demonstration and study of currents varying with time.

189743448Leipzig Johann Ambrosius Barth 1897. No wrappers. In "Annalen der Physik und Chemie Neue Folge" Bd. 60 No 3. Pp. 401-576 textillustr. and 2 folded plates. the entire issue offered "Heft 3". Braun's paper: pp. 552-559 a. 6 textillustrations showing the Braun tube and its operations. Clean and fine. 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. unknown

183448203Leipzig Johann Ambrosius Barth 1834. 8vo. Contemp. hcalf. Spine gilt and with gilt lettering. Spine slightly rubbed. In: "Annalen der Physik und Chemie. Hrsg.von Poggendorff" Bd. 35. X6308 pp. a. 5 folded lithographed plates. Entire volume offered. Faraday's papers: pp. 1-45 a. 222-226 1 plate 8. Reihe - pp. 413-444 9. Reihe. Stamp to verso of titlepage and verso of plates. Clean and fine printed on good paper. First appearance in German - prepared by Faraday himself for publication in Annalen - of two groundbreakings papers in chemistry and physiscs.In the FIRST PAPER 8. Reihe Faraday brings forth the idea "that the atoms of matter are in some way endowed or associated with electrical powers to which they owe their most striking qualities and amongst them their mutual chemical affinity." He showed how natural it is to suppose that the electricity which passes through the electrolyte is exact equivaklent of that which is possessed by the atoms separated at the electrode: which implies that there is A CERTAIN ABSOLUTE QUANTITY OF THE ELECTRIC POWER ASSOCIATED WITH EACH ATOM OF MATTER.- Faraday further verifies that the electricity of the violtaic pile is proportionate in its intensity to the intensity of the affinities concerned in its production. - Dealing with the the decompositions in electrolysis he shows that THE FORCES TERMED CHEMICAL AFFINITY AND ELECTRICITY ARE THE SAME.In the SECOND PAPER 9. Reihe Faraday independent of Henry's discovery of the same phenomena in 1832 discovers SELF-INDUCTION or the "extra current" and points out the importent influence it must have in the construction of electro-magnetic machines electro-motors."Faraday showed that the powerful momentary current which was observed when the circuit was interrupted was really an induced current governed by the same laws as all other induced currents but with this peculiarity that the induced and inducing current now flowed in the same circuit. In fact the current in its steady state establishes in the surrounding region a magnetic field whose lines of force are linked with the circuit; and teh removal of these lines of forcewhen the circuit is broken originates an induced current which reatly reinforces the primary current just before its final extinction."Whittaker in "A History of the Aether and Electricity""In the series of experiments which are detailed in this paper the author inquires into the causes of some remarkable phenomena relating to the action of an electrical current upon itself under certain circumstances wherby its intensity is highly exalted and occasionally increased to ten twenty or even fifty times that which it originally possessed."Abstract. unknown
