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, 1903-1957, founder of modern detonation theory and computer science
"The scientist describes what is; the engineer creates what never was."
Theodore von Kármán, 1881-1963, father of aerothermochemistry
