He should have started his lecture with the chart shown at the 26 minute mark. Saying when we measure the pressures on the airfoil, we see high pressure at the front and bottom of the airfoil. Let me explain what is going on…

I found his explanation at the 13 minute mark to be hand wavy. He talked about flow turning and momentum change but just hand waved away why pressure is higher at the bottom of the wing.
