Systems are sets of entities, physical or abstract, comprising a whole where each component interacts with or is related to at least one other component and they all serve a common objective. The scientific research field which is engaged in the interdisciplinary study of universal system-based properties of the world is general system theory, systems science and recently systemics. This field investigates the abstract properties of matter and mind, and their organization, searching for concepts and principles which are independent of the specific domain, substance, and type of system, and of the spatial and/or temporal scales of its existence.

Systems science can be viewed as ... "a metalanguage of concepts and models for interdisciplinary use, still now evolving and far from being stabilized. This is the result of a slow process of accretion through inclusion and interconnection of many notions, which came and are still coming from very different disciplines. The process started more than a century ago, but has gathered momentum since 1948 through the pioneering work of Norbert Wiener, John von Neumann, Ludwig von Bertalanffy, Heinz von Foerster and W. Ross Ashby, among many others" (Charles François, 1999).

Cybernetics is the interdisciplinary study of the structure of complex systems, especially communication processes, control mechanisms and feedback principles. Cybernetics is closely related to control theory and systems theory.

Contemporary cybernetics began as an interdisciplinary study connecting the fields of control systems, electrical network theory, mechanical engineering, logic modeling, evolutionary biology and neuroscience in the 1940s. Other fields of study which have influenced or been influenced by cybernetics include game theory, system theory (a mathematical counterpart to cybernetics), psychology (especially neuropsychology, behavioral psychology, and cognitive psychology), and also philosophy, and even architecture.

Interview with Herman Kahn, author of On Escalation, May 11, 1965.jpg

Herman Kahn (February 15, 1922 – July 7, 1983) was a military strategist and systems theorist employed at RAND Corporation, USA. His theories contributed to the development of the nuclear strategy of the United States.

Kahn's major contributions were the several strategies he developed during the Cold War to contemplate "the unthinkable," namely, nuclear warfare, by using applications of game theory. During the mid-1950s, the Dwight D. Eisenhower administration's prevailing nuclear strategy had been one of "massive retaliation", enunciated by Secretary of State John Foster Dulles.

Did you know

  • ...that a successful experimental system must be stable and reproducible enough for scientists to make sense of the system's behavior, but unpredictable enough that it can produce useful results?
  • ... that the American systems scientist John Nelson Warfield found systems science to consist of a hierarchy of sciences.
    • Beginning at the base, with a science of description,
    • continuing vertically with a science of design,
    • then a science of complexity,
    • and next a science of action, called "Interactive management".
