Abstract: There are networks in almost every part of our lives. Some of them are familiar and obvious: the Internet, the power grid, the road network. Others are less obvious but just as important. The patterns of friendships or acquaintances between people form a social network. Boards of Directors join together in networks of corporations. The workings of the body's cells are dictated by a metabolic network of chemical reactions. In recent years, sociologists, physicists, biologists, and others have learned how to probe these networks and uncover their structures, shedding light on the inner workings of systems ranging from bacteria to the whole of human society. This lecture looks at some new discoveries regarding networks, how these discoveries were made, and what they tell us about the way the world works. http://www.santafe.edu/events/abstract/276
<>The System Dynamics Group was founded in the early 1960s by Professor Jay W. Forrester at MIT. At that time, he began applying what he had learned about systems during his work in electrical engineering to every day kinds of systems. What makes using system dynamics different from other approaches to studying complex systems is the use of feedback loops. Stocks and flows help describe how a system is connected by feedback loops which create the nonlinearity found so frequently in modern day problems. Computers software is used to simulate a system dynamics model of the situation being studied. Running “what if” simulations to test certain policies on such a model can greatly aid in understanding how the system changes over time. See http://web.mit.edu/sdg/www/

Systems Theory: the transdisciplinary study of the abstract organization of phenomena, independent of their substance, type, or spatial or temporal scale of existence. It investigates both the principles common to all complex entities, and the (usually mathematical) models which can be used to describe them. See: http://pespmc1.vub.ac.be/SYSTHEOR.html
Systems theory or general systems theory or systemics is an interdisciplinary Interdisciplinarity article field which studies systems System article as a whole. Systems theory was founded by Ludwig von Bertalanffy Ludwig von Bertalanffy article , William Ross Ashby William Ross Ashby article and others between the 1940s 1940 article and the 1970s 1970 article on principles from physics Physics article , biology Biology article and engineering Engineering article and later grew into numerous fields including philosophy Philosophy article , sociology Sociology article , organizational theory Organizational theory article , management Management article , psychotherapy Psychotherapy article (within family systems therapy Family systems therapy article ) and economics Economics article among others. Cybernetics Cybernetics article is a related field, sometimes considered as a part of systems theory. See http://www.definition-info.com/Systemics.html
