(functioning as singular)the branch of science concerned with control systems in electronic and mechanical devices and the extent to which useful comparisons can be made between man-made and biological systemsSee also feedback (def. 1)
coined 1948 by U.S. mathematician Norbert Wiener (1894-1964) from Greek kybernetes "steersman" (metaphorically "guide, governor") + -ics; perhaps based on 1830s French cybernétique "the art of governing."
The future offers very little hope for those who expect that our new mechanical slaves will offer us a world in which we may rest from thinking. Help us they may, but at the cost of supreme demands upon our honesty and our intelligence. [Norbert Weiner, "God and Golem, Inc.," 1964]
The scientific study of communication and control processes in biological, mechanical, and electronic systems. Research in cybernetics often involves the comparison of these processes in biological and artificial systems.
The general study of control and communication systems in living organisms and machines, especially the mathematical analysis of the flow of information. The term cybernetics was coined by Norbert Wiener, an American mathematician of the twentieth century.
