If you ask any more questions I'l just hand you over to Anthony from now on. I don't think actually flying an airplane will explain the aerodynamics of lift any more than driving a car will help with understanding of rack-and-pinion. Yes, there will be an an intuition that will develop, but that's going to happen anyway, and that would have happened even if I were a 16-year-old sitting in pilot's seat. Doesn't mean that 16-year-old is going to understand aerodynamics. Let's face it. A large pecentage of people walking this planet think there is a "suction" force. I was watching the History Channel one day, and the narrator actually used that term - a "suction" force, and he did not mean the force that is on the other side of the barrier where the "suction" force was being applied. I've also seen countless erroneous explantions on the same channel about electronics which I do know about. Typically the narrator will say voltage when he meant current, or energy when he meant power. I'm more of a mind-over-matter type. I'll get my license and fly around and develop the intuition that you mention, certainly, but that's not enough. -Le Chaud Lapin- |
