A lightning rod or lightning conductor (British English) is a metal rod mounted on a structure and intended to protect the structure from a lightning strike. If lightning hits the structure, it is most likely to strike the rod and be conducted to ground through a wire, rather than passing through the structure, where it could start a fire or ...
The lightning rod invented by Benjamin Franklin in 1752 suggested a way of avoiding the common problem of lightning causing damage to the wooden sailing ships of the period. In Britain, the Royal Navy chose a protection system with a chain draped into the sea from the top of the mast as a lightning conductor. This system proved unsatisfactory ...
Aspiring conductors need to obtain a broad education about the history of music, including the major periods of classical music and regarding music theory. Many conductors learn to play a keyboard instrument such as the piano or the pipe organ , a skill that helps them to be able to analyze symphonies and try out their interpretations before ...
French physicist Alfred Kastler invented the MASER. 1951: First nuclear power plant in the US 1952: Japanese engineer Jun-ichi Nishizawa invented the avalanche photodiode [20] 1953: First fully transistorized computer in the U.S. 1958: American engineer Jack Kilby invented the integrated circuit (IC). 1960: American engineer Theodore Maiman ...
Conductors view their gestures as the primary means to communicate musical ideas, whether or not they choose to use batons. Leonard Bernstein is quoted as saying, "If one [the conductor] uses a baton, the baton itself must be a living thing, charged with a kind of electricity, which makes it an instrument of meaning in its tiniest movement."
The steam turbine invented by Sir Charles Parsons in 1884 is still used to convert the thermal energy of steam into a rotary motion that can be used by electro-mechanical generators. Such generators bear no resemblance to Faraday's homopolar disc generator of 1831, but they still rely on his electromagnetic principle that a conductor linking a ...
Alternative music’s eternal paranoid android, Thom Yorke has guided Radiohead through self-deprecating college-rock, triple-guitar art-rock, mindfuck electronica and most spaces between. He’s ...
The famous kite experiment enabled the Philadelphia group to established what had been surmised by others, that lightning was identical to the mild charge of electricity produced by the friction of the electrostatic machine. Franklin invented the lightning rod, which goes down in history as the first practical electrical invention.
