joe, listen...
i'm going to presume that you've never taken a physics course before, have you? didn't think so.
when you take a physics course, you don't quietly sit there and accept the authority of the professor. that's not how science works, joe.
rather, the professor takes it upon his or herself to demonstrate the argument using a series of mathematical deductions. and, at every step of the way the professor - if it is a good professor - will invite you to challenge and question the results being developed.
further, a physics course will have something called a lab component where the student will actually do the experiments. this is fundamental, because science does not operate on authority but on the ability of the scientist to discover results on their own.
his comments actually give a lot away about what he thinks, and it's not very flattering to his intelligence.
