Beware of this video:

Almost everything it says about the physics is wrong.
Disparaging Bernoulli is wrong.
Bernoulli was a smart guy. Bernoulli's theorem is still a theorem.
It is not restricted to internal aerodynamics.
Explaining lift in terms of Coanda is wrong.
I do not have time to go into the details right now.
I have a 20-hour job to do today, working the polls.
For now, you can read a reasonably careful explanation here:
