Cyberneticist Cyberneticist A cyberneticist or a cybernetician is a person who practices cybernetics. Heinz von Foerster once told Stuart Umpleby that Norbert Wiener preferred the term "cybernetician" rather than "cyberneticist", perhaps because Wiener was a mathematician rather than a physicist. The word cyberneticist was used by Nicolas Rashevsky who began as a theoretical physicist, Robert Rosen, who began his career as a mathematician, regarded Neuro cybernetics—and more generally Biocybernetics—as fields closely allied to Mathematical Biology and Mathematical Biophysics in which control theory and dynamical system theories also play significant roles. Today "cybernetician" is preferred by members of the American Society for
Complex system or communities. Complex systems may have the following features: Although it is arguable that humans have been studying complex systems for thousands of years, the modern scientific study of complex systems is relatively young in comparison to established fields of science such as physics and chemistry. The history of the scientific study of these systems follows several different research trends. In the area of mathematics, arguably the largest contribution to the study of complex systems was the discovery of chaos in deterministic systems, a feature of certain dynamical systems that is strongly related to nonlinearity. The study of neural networks
