In electrical engineering, we have our own set of fundamental principles. The "terminal" set of primitives governing electronics (electrostatics and electrodynamics) is Maxwells Equations http://en.wikipedia.org/wiki/Maxwell_equation. [Ironically, during his lifetime, Maxwell was also someone who was a leading expert on aerodynamics. The notions of gradients, the Laplacian, and scalar potentials have strong parallels in both fields.] In EE, we have out own myths, like power lines causing brain cancer, but when they arise, the experts work hard to show indisputable evidence, verifiable, rigorous evidence to the contrary, to nip the non-sense in the bud. We do still have areas of disputes, like what causes shot noise in circuits [http://en.wikipedia.org/wiki/Shot_noise], but on the bread- and-butter basics, you won't find a college-leve textbook speaking untruth. So naturally I am extremely surprised to see this happening in aerodynamics. You are, after all, the rocket scientists. ![]() Really? Many books still can't agree on the definition of current. Some say it is the movement of electrons and some say it is the movement of positive charge and some say it us both. Which is the absolute truth, Mr. Wizard? Matt |
