Cybernetics, Second Edition: or Control and Communication in the Animal and the Machine

nCybernetics or Control and Communication in the Animal and the Machine (Reprint of 1961 Second Edition) by Norbert Wiener is a seminal work that had long-ranging implications for the fields of computers, automation, electrical engineering, neuroscience, and communications. nAuthor Norbert Wiener (b. 1894, d. 1964) was a mathematician and philosopher, as well as a long-term professor of mathematics at the Massachusetts Institute of Technology (MIT). A child prodigy, Wiener graduated from high school at just 11 years old, and completed his BA in mathematics from Tufts University at the age of 14. By age 19, he had received his Ph.

D from Harvard for a dissertation on mathematical logic. nWhile he was later a pacifist, Wiener contributed to the war efforts in both world wars, working on ballistics during World War I and anti-aircraft guns during World War II. By the late 1940s, he had grown concerned with the militarization of science, and stopped contributing to any military projects or taking government funding. nWiener taught philosophy at Harvard during his early career, but was unable to secure a permanent teaching position-a fact he attributed to anti-Semitism, as the son of Jewish immigrants. After World War I, he was hired at MIT, where he would teach for the rest of his career. nIn addition to teaching, Wiener conducted research in cognitive science and developed theories in cybernetics, computing, and automation. He also wrote many books and articles on these topics, as well as two autobiographical works. nCybernetics or Control and Communication in the Animal and the Machine is one of Wiener's best-known works. Cybernetics refers to the science of control systems and communications in both machines and living beings. This book demonstrates the first public use of the term and describes the way self-regulating mechanisms (including the human brain) function through the receipt, processing, and use of external feedback. nThis interdisciplinary work is the result of years of discussions with medical scientists, physicians, mathematicians, and physicists, giving it a wide range of influences both on the book's concepts and on the fields that it impacted. The book has been foundational for research into computing, electronic engineering, automation, telecommunications, and neuroscience. nAt the core of cybernetics are feedback loops, the inflow of information and subsequent response. Both philosophical and technical, the book presents
