This is a quote I read and I am having problems understanding it:
"Lift is produced by the changing direction of the flow around a wing. The change of direction results in a change of velocity (even if there is no speed change, just as seen in uniform circular motion), which is an acceleration. To change the direction of the flow therefore requires that a force be applied to the fluid; lift is simply the reaction force of the fluid acting on the wing."
The part I do not understand is that lift is the reaction force of the fluid on the wing, should it not be the other way arround?
