For all of its complicated formulas, and mathematics, in the final analysis, aerodynamics is the study of how to accelerate air to produce a force to sustain, propel, or maneuver a flying machine.
Lou,
Your description is pretty darn good. I would only make one comment, about the part quoted above. The discipline of aerodynamics is really more about the pressure exerted by the air on the aircraft. Even though the deflection of the surrounding air is a necessary and inescapable part of the phenomenon, the aspect that we humans find useful to study, at least in the design of aircraft, is the part that occurs at the surface of the aircraft. This is where we make design decisions, and indeed, the pressure distribution on the wing could be viewed as the thing which is actually designed in the process of designing a wing.
