This asks for two answers:

First, the why.  Nothing has changed since the time St. Paul visited Athens, and he found that “all the Athenians and the foreigners who lived there would spend their time in nothing except telling or hearing something new.”  

Second, the what to do about it.  First step, we must stop teaching physics at school as if it were a branch of applied algebra.  (And our university physics departments must stop teaching the subject as if their primary aim were to produce more university physicists. )

Thirdly, I would not allow anyone to perform in Bertolt Brecht’s play Life of Galileo unless they had a reasonable grounding as to what Galileo actually achieved in the field of mechanics.  Although previously Dominic de Soto had moved towards the idea that propelled motion and falling motion were not, as Aristotle thought, different types of motion, it was Galileo who put this on a firm foundation and launched modern mechanics.
