Cybernetics is an interdisciplinary science that studies control processes in animate and inanimate systems, machines, and creatures, with a focus on self-regulation achieved through feedback loops.
Norbert Wiener defined "cybernetics" as the study of control and communication in animals and machines in his book of the same name published in 1948.
The name cybernetics is derived from the Greek kybernts (steersman, governor, pilot, or rudder, which is the same root as governance).
Machines based on cybernetics, robotics, and biology have become fairly popular because of the movie industry. A cyborg, which is an organism with both artificial and natural systems, is a machine like this.
