Page "Error" Paragraph 19

The word cybernetics stems from the Greek Κυβερνήτης ( kybernētēs, steersman, governor, pilot, or rudder — the same root as government ).

In applying corrections to the trajectory or course being steered cybernetics can be seen as the most general approach to error and its correction for the achievement of any goal.

The term was suggested by Norbert Wiener to describe a new science of control and information in the animal and the machine.

Wiener's early work was on noise.
