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
Scientific imperialism Scientific imperialism Scientific imperialism is a term that appears to have been coined by Dr. Ellis T. Powell when addressing the Commonwealth Club of Canada on 8 September 1920. Though he defined imperialism as "the sense of arbitrary and capricious domination over the bodies and souls of men," yet he used the term "scientific imperialism" to mean "the subjection of all the developed and undeveloped powers of the earth to the mind of man." In modern parlance, however, scientific imperialism refers to situations in which critics perceive science to act imperiously. Philosopher of science John Dupré described it (in his
