Spark from the Deep: How Shocking Experiments with Strongly Electric Fish Powered Scientific Discovery (Animals, History, Culture)
William J. Turkel
Spark from the Deep tells the tale of ways humans got here to appreciate and use electrical energy via learning the advanced mechanisms of strongly electrical fish. those animals have the capacity to surprise power prey or would-be predators with high-powered electric discharges.
William J. Turkel asks thoroughly clean questions on the evolutionary, environmental, and ancient elements of people’s curiosity in electrical fish. motivated by way of painful encounters with electrical catfish, torpedos, and electrical eels, humans realized to harness the facility of electrical surprise for scientific treatments and at last constructed applied sciences to shop, transmit, and keep watch over electrical energy. Now we glance to those fish as an thought for engineering new sensors, computing device interfaces, self reliant undersea robots, and energy-efficient batteries.

(despite the truth that his experiments may develop into a staple of paranormal literature).40 One will not be capable of create existence de novo from an electrical spark, yet a robust adequate discharge may perhaps sincerely be used to forestall flow and respiratory and, whilst the stipulations have been correct, can be used to begin them up back. a number of the comparable ordinary philosophers who explored the connections among actual, chemical, atmospheric, and animal electricity—Cavendish, Priestley, Davy, and others—also.
find the money for to burn out string galvanometer wires, so he determined to take advantage of the capillary tube electrometer in its place. even though capillary electrometry had fallen out of fashion with physiologists via the mid-1920s—and Adrian was once one of many final to exploit the technique—the purposes for its decline have been inconsequential after the appearance of vacuum tube amplification. The electrometer used to be quickly, sturdy, foolproof, and its electric features have been an exceptional fit for the amplifier. however, while Adrian validated.
