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

Advances in Complex Systems Advances in Complex Systems (ACS) is a peer-reviewed journal published quarterly by World Scientific providing a multidisciplinary perspective to the study of complex systems. The journal was founded in 1997 and aims to "promote cross-fertilization of ideas among all the scientific disciplines having to deal with their own complex systems". Papers in ACS are divided into five sections, each managed by a separate editor: Physics and Mathematics; Computer Sciences; Biological Systems; Social and Economic Systems;
