"Insulator" Quotes from Famous Books
 ... be instantaneous; but it was afterwards found that its velocity depended on the nature of the conductor, its resistance, and its electro-static capacity. Faraday showed, for example, that its velocity in a submarine wire, coated with insulator and surrounded with water, is only 144,000 miles a second, or still less. Wheatstone's device of the revolving mirror was afterwards employed by Foucault and Fizeau to measure ...

... subject, Correll fixed a pointed collector—a miniature lightning-conductor—above the flagpole on the summit of the roof. A wire was led through an insulator, so that the stream of electricity could be subjected to experiment in the Hut. Here a "brush" of blue light radiated outwards to a distance of one inch.
