…inventors and doctors and engineers don’t typically even bother learning relativity. Should I repeat that? Complain to engineering departments and medical schools if you think that should change. Nothing useful has even been designed or built using relativity. If you want to look and look and look for a counterexample then you’ll be wasting your time. I’m not going to waste mine.
