History of computer science probability theory to the problem of how to best encode the information a sender wants to transmit. This work is one of the theoretical foundations for many areas of study, including data compression and cryptography . From experiments with anti-aircraft systems that interpreted radar images to detect enemy planes, Norbert Wiener coined the term cybernetics from the Greek word for "steersman." He published "Cybernetics" in 1948, which influenced artificial intelligence. Wiener also compared computation, computing machinery, memory devices, and other cognitive similarities with his analysis of brain waves. The first actual computer bug was a moth. It was stuck in

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;
