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
Mathematics and Mechanics of Complex Systems both printed and electronic forms. "MEMOCS" publishes articles from diverse scientific fields with a specific emphasis on mechanics. Its contents rely on the application or development of rigorous mathematical methods. The journal also publishes original research in related areas of mathematics of well-established applicability, such as variational methods, numerical methods, and optimization techniques, as well as papers focusing on and clarifying particular aspects of the history of mathematics and science. Among the contributors are Graeme Milton, Geoffrey Grimmett, David Steigmann, Mario Pulvirenti and Lucio Russo.
