His team's work on antiaircraft directors -- devices that observe enemy planes or missiles and calculate the aim of countermissiles -- became crucial when German rockets were used in the blitz of England. Webb25 jan. 2024 · Shannon showed that Boolean algebra could be used to move away from the relays themselves, into a more abstract understanding of the function of a circuit. He used this algebra of logic to analyze, and then synthesize, switching circuits and to prove that the overall circuit worked as desired. shuttle tuscaloosa to birmingham
