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
If the journey is not what you expect, do not be surprised. All models are wrong, but some are useful. -- George Box
