Abstract

A model always means a more or less drastic simplification of some real system in order to describe or even to explain a phenomenon which is experimentally observed in that real system. A description of a phenomenon is a mathematical formulation of its constitutive variables, mostly in the form of a differential equation or a system of differential equations which contain the experimental parameters of the phenomenon as constants. An explanation goes beyond a pure description in that it reduces the occurrence of the phenomenon to more elementary relationships or laws which were known already. It is evident that the border line between a descriptive and an explanatory model is hazy and very often depends on the point of view.
