The system has been successfully used to model a variety of physical processes such as stiffening springs, beam buckling, nonlinear electronic circuits, superconducting Josephson parametric amplifiers, and io

It is, however, on account of its electronic nature, also similar to a computing device and, therefore, electronic circuits are also used as analog computers to model more elaborate experimental

Typically, the right-hand side of these equations is a nonlinear function of the variables .. and .., i.e., (12.1) is a nonlinear dynamical system.

Polymineral-Metasomatic CrystallogenesisIn everyday life we feel safer and more comfortable with predictability and determinism: in technically controlled processes, small mechanical forces are expected to cause minor changes; the time-table of trains is hopefully reliable; the motion of the earth and moon around the sun are thought to be regular and stable.
