Description of Lift On An Airfoil
There are several ways to explain how an airfoil generates lift. Some are more complicated or more mathematically rigorous than others; some have been shown to be incorrect. For example, there are explanations based directly on Newton’s laws of motion and explanations based on Bernoulli’s principle. Either can be used to explain lift. This article will start with the simplest explanation; more complicated and alternative explanations will follow.

At last, some curious traveller from Lima will visit England and give a description of the ruins of St Paul’s, like the editions of Balbec and Palmyra.”

“And then he would lift this finest
of furniture to his big left shoulder
and tuck it in and draw the bow
so carefully as to make the music
almost visible on the air.”
