"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 CONTACT INFO
