Cybernetics,

Cybernetics describes the application of statistical mechanics methods to communications engineering. Its subject matter ranges from such control mechanisms as servo-mechanisms, mathematical calculators, and automatic pilots, to the nerves and brain of the human body.

This is a study of human control functions and mechanico-electrical systems designed to replace them. As such it impinges on every branch of science. It is the outgrowth of extensive theoretical study and experimentation by Dr. Wiener and a group of outstanding scientists -- including physiologists, psychologists, mathematicians, and electrical engineers.
