Accounts Quote by John von Neumann
“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-that is, correctly to describe phenomena from a reasonably wide area.”

Science builds abstract mathematical models to predict phenomena rather than fully explain them.
In simple terms: Models predict, not explain.
Use models, test predictions.
