A propos de cet article
FIRST EDITION, FULL VOLUME 152, PART II OF THE 1862 PHILOSOPHICAL TRANSACTIONS COMPLETE WITH A NUMBER OF NOTABLE PAPERS. Handsomely illustrated with 48 plates. Fleeming Jenkin was a professor of engineering at Edinburgh as well as an imaginative electrician and cable engineer of note. Present here is Jenkin's important paper on the electrical theory of submarine cables in undersea telecommunications. In it, Jenkin makes "a determination. of the specific inductive capacity of gutta-percha. This was the very first true measurement of the specific inductive capacity of a dielectric which had been made after the discovery by Faraday of the existence of the property, and his primitive measurement of it. At the time when Jenkin made his measurements the existence of specific inductive capacity was either unknown, or ignored, or denied, by almost all the scientific authorities of the day" (Memoir of Fleeming Jenkin). Note that Part II of this paper appeared in a different volume and we offer it separately. Also included: Joule on the heating effects of fluids in motion and the results of experiments "on the difference between the temperatures of an elastic fluid on the high-and-low pressure sides of a porous plug through which it was transmitted. Joule is well known for his discovery of Joule's Law, the connection between heat and mechanical work, where heat is a form of energy. "From Joule's extensive and reliable data [presented in this paper] Thomson derived an empirical law [stating] that the cooling effect per unit pressure difference varie[s] as the inverse square of the absolute temperature" (Carwell, 202). Also included: a paper by Stokes investigating the spark spectra of metals, spectra of the electric arc, form and effects of the electrodes; Cayley on analytical geometry; Hopkins mathematical theory of the motions of glaciers; Robinson on the spectrum of the electric light given by a compound body is not the superposed spectra of its elements.
