Norbert Wiener firing of anti-aircraft guns caused Wiener to investigate information theory independently of Claude Shannon and to invent the Wiener filter. (To him is due the now standard practice of modeling an information source as a random process—in other words, as a variety of noise.) His anti-aircraft work eventually led him to formulate cybernetics. After the war, his fame helped MIT to recruit a research team in cognitive science, composed of researchers in neuropsychology and the mathematics and biophysics of the nervous system, including Warren Sturgis McCulloch and Walter Pitts. These men later made pioneering contributions to computer science and artificial
Advances in Complex Systems 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; and Traffic and Environmental Systems. The journal is indexed in "Mathematical Reviews, CSA Human Population and the Environment Abstracts, CSA Risk
