1850408771850. <p>Rare 19th Century American Electricity Broadside</p> <p>Electricity Wonderful experiments! At the Liberty Hall Groton this evening Feb. 19 inst. Dr. Fisk begs to inform the ladies and gentlemen of this place that he will give one night of pleasing and instructive amusement . . . Broadside. Woodcut illustrations. N.p.: Samuel B. Hall n.d. ca. 1850. 627 x 225 mm. Small portion of one corner torn not affecting text some creasing minor stains but very good.</p> <p>Rare nineteenth-century American broadside advertising Dr. Fisk's traveling show offering a "pleasing and instructive" demonstration of the many and varied uses of electricity. Among the marvels promised were "a splendid railway engine . . . driven by electricity 200 miles per hour" "electro-magnetic engines of immense power . . . driving a variety of useful machines" and "cannons and fireworks . . . fired by electricity." The broadside also proclaims that "a medical galvanizing machine will be at work for the benefit of all" which Dr. Fisk whom we have not been able to identify would use to make "chickens . . . fly without heads" and "sheep that have been dead some time . . . jump and run about." The broadside has blank spaces for inserting the place and date of Dr. Fisk's performance which have been filled in with the words "Liberty Hall Groton Connecticut" and "Feb. 19" in pencil in a nineteenth-century hand. </p> . unknown books

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

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

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

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
