- the study of automatic control and communication functions in both living organisms and mechanical and electronic systems, involving the application of statistical mechanics to feedback: During WW II, cybernetics was used to develop radar-controlled antiaircraft guns; today the field is working on prosthetic arms and legs linked directly to the human nervous system.
- 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 systems
