Norbert Wiener the amount of noise present in a signal by comparison with an estimate of the desired noiseless signal. Wiener developed the filter at the Radiation Laboratory at MIT to predict the position of German bombers from radar reflections. It is necessary to predict the future, because by the time the shell reaches the vicinity of the target, the target has moved, and maybe has changed direction slightly. They even modeled the muscle response of the pilot, which led eventually to cybernetics. The unmanned V1's were particularly easy to model, and on a good day, American guns fitted with Wiener filters
William James Sidis of intelligence as "silly, pedantic, absurd, and grossly misleading". Regardless of the exaggerations, Sidis is judged by other high IQ peers such as MIT Physics professor Daniel Frost Comstock and notable American mathematician Norbert Wiener to have had real ability. Sidis' life and work, particularly his ideas about Native Americans, are extensively discussed in Robert M. Pirsig's book "" (1991). Sidis is also discussed in "Ex-Prodigy", an autobiography by mathematician Norbert Wiener (1894–1964), who was a prodigy himself and a contemporary of Sidis at Harvard. A Danish author Morten Brask wrote a fictional novel based on Sidis' life; "The Perfect
