A professor of mine once said to me that all teaching was a process of lying, and then of replacing the lies with successively better approximations of the truth. This is the opposite of what Feynman thought. He said, and I agree, something like "the hard part about teaching is making concepts simple without saying things that are false." The whole challenge of teaching is NOT lying, but instead saying simple things that are still true. That said, I see the appeal of choosing omega.
