Talcott Parsons science. Parsons also became strongly interested in systems theory and cybernetics and began to adopt their basic ideas and concepts to the realm of social science, especially the work of Norbert Wiener (1894–1964) had his attention. Some of the students who arrived at the Department of Social Relations in the years after the Second World War were David Aberle, Gardner Lindzey, Harold Garfinkel, David G. Hays, Benton Johnson, Marian Johnson, Kaspar Naegele, James Olds, Albert Cohen, Norman Birnbaum, Robin Murphy Williams, Jackson Toby, Robert N. Bellah, Joseph Kahl, Joseph Berger, Morris Zelditch, Renee Fox, Tom O'Dea, Ezra Vogel, Clifford Geertz,
Norbert Wiener many results now widely known such as the non-differentiability of the paths. Consequently, the one-dimensional version of Brownian motion was named the Wiener process. It is the best known of the Lévy processes, càdlàg stochastic processes with stationary statistically independent increments, and occurs frequently in pure and applied mathematics, physics and economics (e.g. on the stock-market). Wiener's Tauberian theorem, a 1932 result of Wiener, developed Tauberian theorems in summability theory, on the face of it a chapter of real analysis, by showing that most of the known results could be encapsulated in a principle taken from harmonic analysis. In its
