Cybernetics is a theory of the communication and control of regulatory feedback. The term cybernetics stems from the Greek Κυβερνήτης (meaning steersman, governor, pilot, or rudder). Cybernetics is the discipline that studies communication and control in living beings and in the machines built by humans.

A more philosophical definition, suggested in 1958 by Louis Couffignal , one of the pioneers of cybernetics in the 1930s, considers cybernetics as "the art of assuring efficiency of action" (see external links for reference).

1 History

The word cybernetics is found in the Gorgias by Plato, it also had a French usage, though Norbert Wiener, who later developed the modern form, wasn't aware that the physicist André-Marie Ampère (1775-1836) had already used it for his classification of the sciences to define "how the citizens can enjoy a peaceful time".

In the late 1700s James Watt's steam engine had a governor, a simple feedback mechanism, a cornerstone of cybernetic theory. In 1868 James Clerk MaxwellJames Clerk Maxwell ( June 13, 1831 November 5, 1879) was a Scottish physicist, born in Edinburgh. Maxwell developed a set of equations expressing the basic laws of electricity and magnetism as well as the Maxwell distribution in the kinetic theory of gas published an article on governors.

Despite being widely influential within cybernetics, systems theory and, more recently, complex systems, h and Grey Walter. While cybernetics is generally thought to have American origins, the book itself was actually published in FranceThe French Republic or France ( French: Republique francaise or France is a country whose metropolitan territory is located in western Europe, and which is further made up of a collection of overseas islands and territories located in other continents. where information theory was hailed as a new general discipline which included cybernetics. When asked why he had chosen the name cybernetics, Wiener replied, "I didn't know what else to call it."

In the spring of 1947, Wiener was invited to a congress on harmonic analysis, held in Nancy, France and organized by the bourbakist mathematician, Szolem Mandelbrot (1899-1983), uncle of the world famous mathematician Benoit Mandelbrot.

During this stay in France Wiener received the offer to write a manuscript on the unifying character of this part of applied mathematics, which is found in the study of Brownian motion and in telecommunication engineering. The following summer, back in the United States, Wiener decided to introduce the neologism cybernetics into his scientific theory.

Wiener popularized the social implications of cybernetics, drawing analogies between automatic systems such as a regulated steam engine and human institutions in his best-selling The Human Use of Human Beings : Cybernetics and Society (Houghton-Mifflin, 1950).

Cybernetics is somewhat erroneously associated in many people's minds with robotics, due to uses such as Douglas Adams's Sirius Cybernetics Corporation and the concept of a cyborg, a term first popularized by Clynes and Kline in 1960.
