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
Wiener–Hopf method Wiener–Hopf method The Wiener–Hopf method is a mathematical technique widely used in applied mathematics. It was initially developed by Norbert Wiener and Eberhard Hopf as a method to solve systems of integral equations, but has found wider use in solving two-dimensional partial differential equations with mixed boundary conditions on the same boundary. In general, the method works by exploiting the complex-analytical properties of transformed functions. Typically, the standard Fourier transform is used, but examples exist using other transforms, such as the Mellin transform. In general, the governing equations and boundary conditions are transformed and these transforms are used to define
