Cybernetics is the study of communication and control in machines and living systems.
First-order cybernetics (Norbert Wiener) centred around deviation-limiting feedback control theory and examples. For current work See the IEEE journal: Transactions on Systems, Man, and Cybernetics. (parts A, B &C) <http://www.ieee.org/organisations/pubs/transactions/information.htm>.
Second order cybernetics (Heinz Von Foerster) <http://www.gwu.edu/cgi/asc/> is about complex emergent observing and self-observing learning guidance and control systems. see the Journals: Cybernetics and Human knowing <http://www.imprint-academic.com/C&HK>, and Systems Research and Behavioral Science <www.interscience.wiley.com/journals/srbs>.
