Norbert Wiener the development of the digital theory. Wiener originated cybernetics, a formalization of the notion of feedback, with many implications for engineering, systems control, computer science, biology, philosophy, and the organization of society. Wiener's work with cybernetics influenced Gregory Bateson and Margaret Mead, and through them, anthropology, sociology, and education. A simple mathematical representation of Brownian motion, the Wiener equation, named after Wiener, assumes the current velocity of a fluid particle fluctuates randomly. For signal processing, the Wiener filter is a filter proposed by Wiener during the 1940s and published in 1942 as a classified document. Its purpose is to reduce
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.
