Cybernetics is a transdisciplinary approach for exploring regulatory systems, their structures, constraints, and possibilities. Cybernetics is relevant to the study of systems, such as mechanical, physical, biological, cognitive, and social systems. Cybernetics is applicable when a system being analyzed is involved in a closed signaling loop; that is, where action by the system generates some change in its environment and that change is reflected in that system in some manner (feedback) that triggers a system change, originally referred to as a “circular causal” relationship. Some say this is necessary to a cybernetic perspective. System dynamics, a related field, originated with applications of electrical engineering control theory to other kinds of simulation models (especially business systems) by Jay Forrester at MIT in the 1950s.
A cyborg, short for “cybernetic organism”, is a being with both organic and artificial parts. See for example biomaterials and bioelectronics. The term was coined in 1960 when Manfred Clynes and Nathan S. Kline used it in an article about the advantages of self-regulating human-machine systems in outer space. D. S. Halacy’s Cyborg: Evolution of the Superman in 1965 featured an introduction which spoke of a “new frontier” that was “not merely space, but more profoundly the relationship between ‘inner space’ to 'outer space’ – a bridge…between mind and matter.”
