There are various myths. One language or one way of saying constitutes its own ontology. For example, Greek Myths have ontologies in which Appolo, Venus or Pegasus exists. In same way, Physics presupposes as an entity the velocity or the acceleration which is the universal in ordinary language. A myth in higher level gives forceful instruments to the lower level myth. Physics couldn't fulfil its function without mathematics. Moreover, the higher level myth couldn't give the instruments if the lower level were not a myth. Even the thing language is a myth. And, as a myth, it can ask for a help of physics.
