Welcome to the Institute of Mathematics and its Applications (IMA)!
The Institute of Mathematics and its Applications (IMA) exists to support the advancement of mathematical knowledge and its applications and to promote and enhance mathematical culture in the United Kingdom and elsewhere, for the public good.
It is the professional and learned society for qualified and practising mathematicians, with a membership of around 5,000 comprising of mathematicians from all sectors, as well as those with an interest in mathematics.

Right off the bat I have to turn this off because the lil toy experiment he did by blowing on the cup and the ball popping out. He said its because you passed air over the top of the ball. This is not correct. Why the ball popped out was because the air was forced around the side of the ball and because you can't have the ball and extra Mass of air occupying the same space. The ball is forced to move it would to prove this make the ball much heavier than its cup and suspend the cup. Blow again. This time the ball won't move but the cup will shoot away from the ball.
and as we all can see the wing demo he does the wing is tilted upwards. Meaning the air mass that is being forced into the wing by the fan is hitting the bottom part of the wing. This is what causes lift. Not the foil design. The foil design only makes this effect more efficient. Meaning less force is need to lift the wing. Not what causes the wing to lift in the first place. The wing is essentially ricocheting of the mass of air much in the same way a rock ricochet off of water when you skip a rock on a pond. Each time the flat surface of the makes contact with the water at the right angel and with enough force. The rock ricochet off the water lifts into the air until it loses the engery to maintain lift and it hits the water again and again doing the same thing until enough engery has transferred away from the rock for it to lift any longer and the rock then sinks to the bottom. A plane does this same thing. Without proper engery applied at a proper angle. A plane won't lift. No matter what the design is. This is proven by a plane flying upside down. This us proven by a flat wing design. This is proven when you tilt the planes nose downward. In all these examples the plane ignores this notion that the air foil design is what makes a plane fly.
1:38 What a stupid idea to place your rotor *in front of* your model. The amount of turbulence you create there will never be cancelled by the structure of wooden cubes you made between the airfoil and the rotor. A real wind tunnel literally sucks. You talk about Bernoulli's equation. I just hop the was not based on the concept of "equal traveling time" of air flowing over and under the wing. For that, see ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-UqBmdZ-BNig.html
2:18 wrong, that's exactly where I have been, but you took it away too soon. The rules were "move one place up, down, left or right", right'? I moved from "Start" up, leading me to the face on the lowest row as my first move. Moving up from the upper row leads you ending up in the lowest row. But nice try anyway.
