| The History of Cybernetics
As it is known, the first artificial automatic regulatory system, a water clock, was invented by the mechanic Ktesibios (2-1 century BC) from ancient Greece. In his water clocks water flowed from a source such as a holding tank into a reservoir, then from the reservoir to the mechanisms of the clock. The device used a cone shaped float to monitor the level of the water in its reservoir and adjust the rate of flow of the water accordingly to maintain a constant level of water in the reservoir, so that it neither overflowed nor was allowed to run dry. This was the first artificial truly automatic self-regulatory device that required no outside intervention between the feedback and the control of the mechanism. The word cybernetics was first used in the context of self-governance by Plato (428-348 BC) in the Laws to signify the governance of people. In 1834 Andre Marie Ampere, the French physicist and mathematician, systematized the human knowledge of that time under different numbers. Under number 83 he listed a science that was to deal with the methods of regulating society. Ampere termed this science “cybernetics” from the Greek word “kubernetes” meaning “steersman” or “pilot”. This literal translation embodies much of the modern relevance of the cybernetics principles. After Ampere, however, the term “cybernetic” was forgotten until it appeared again in 1948 in a book of the well-known American mathematician Norbert Wiener (1894-1964). His book was entitled “Cybernetics or Control and Communication in the Animal and the Machine” The name ‘cybernetics’ was coined by N. Wiener to denote the study of “teleological mechanisms”, that is machines with corrective feedback. Wiener was part of a group of very brainy people of various specialties – psychology, mathematics, sociology, philosophy, knowledge management. So, the modern study of cybernetics began at the intersection of neurology, electronic network theory and logic modeling. Wiener popularized the social implications of cybernetics, drawing analogies between automatic systems such as a regulated steam engine and human institutions. The laws described by N. Wiener as the basis if cybernetics greatly interested scientists of many specialties. The foundations of cybernetics were laid and its basic principles were formulated in the works of mathematicians, physicists, physicians and engineers. The works of American scientists Claude Shannon and John von Neumann were of outstanding importance. Thus, the study of control and response to complex systems has been keeping great minds busy for thousands of years, and Wiener seems to be regarded as the chief modern architect. 5.
