What is cybernetics?


Cybernetics is the interdisciplinary study of the structure of regulatory systems. Cybernetics is closely related to control theory and systems theory. Both in its origins and in its evolution in the second-half of the 20th century, cybernetics is equally applicable to physical and social (that is, language-based) systems.

Contemporary cybernetics began as an interdisciplinary study connecting the fields of control systems, electrical network theory, mechanical engineering, logic modeling, evolutionary biology, neuroscience, anthropology, and psychology in the 1940s, often attributed to the Macy Conferences.

Complexity theory


Complexity theory may refer to:

  • The study of complex systems.
  • Another name for Chaos theory.
  • Computational complexity theory, a field in theoretical computer science and mathematics dealing with the resources required during computation to solve a given problem.
  • The theoretical treatment of Kolmogorov complexity of a string studied in algorithmic information theory by identifying the length of the shortest binary program which can output that string.
  • Complexity theory and organizations or complexity theory and strategy, which have been influential in strategic management and organizational studies and incorporate the study of complex adaptive systems.
  • Complexity economics, the application of complexity theory to economics.
