The sciences do not try to explain, they hardly even try
to interpret, they mainly make models. By a model is meant a
mathematical construct which, with the addition of certain
verbal interpretations, describes observed phenomena. The
justification of such a mathematical construct is solely and
precisely that it is expected to work.
-- John Von Neumann
