Default RE: Bernoulli vs Newton

Here we go again...

FWIW, from a physics point of view the whole Newton vs. Bernoulli debate is rather absurd. There is no conflict between Newtons's laws and Bernoulli's law. Newton's laws explain on a microscopic level how a wing produces lift by deflecting air molecules downward causing a reaction force that we on a macroscopic level observe as lift and drag. What Bernoulli's law does is simply to keep track of the pressure and velocity changes that will occur in the vicinity of the wing as a result of the airstream being deflected.
