Further, Noelle-Neumann describes the spiral of silence as a dynamic process, in which predictions about public opinion become fact as mass media's coverage of the majority opinion becomes the status quo, and the minority becomes less likely to speak out.
Von Neumann introduced the study of rings of operators, through the von Neumann algebras. A von Neumann algebra is a *-algebra of bounded operators on a Hilbert space that is closed in the weak operator topology and contains the identity operator. The von Neumann bicommutant theorem shows that the analytic definition is equivalent to a purely algebraic definition as an algebra of symmetries.
