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
Stephen L. Adler to Hamiltonian equations of motion. The construction of a statistical mechanics of these matrix models leads, so Adler says, to an "emergent effective complex quantum field theory". Adler's Trace Dynamics has been discussed in relation to the differential space theory of quantum systems by Norbert Wiener and Amand Siegel, to its variant by David Bohm and Jeffrey Bub, and to modifications of the Schrödinger equation by additional terms such as the quantum potential term or stochastic terms, and to hidden variable theories.
