Word Origin & History
AlgolBeta Persei, variable star in the constellation Perseus, late 14c., lit. "the Demon," from Arabic al-ghul "the demon." It corresponds, in modern representations, to the gorgon's head Perseus is holding, but it probably was so called because it visibly varies in brightness every three days, which sets
EXPANDit apart from other bright stars. The computer language (1959) is a contraction of algo(rithmic) l(anguage); see
algorithm.
