Be aware, though, that not everyone agrees with this widely accepted explanation. Jef Raskin, who among many other amazing accomplishments created the Macintosh computer project, was convinced that the commonly held theory for how wings create lift according to the Bernoulli principle is wrong. I won’t even try to simplify his explanation because it’s way over my head. I’ll tell you this, though, the question that got him thinking there had to be more to the explanation than just the Bernoulli effect was this: “If the Bernoulli effect explains lift, then how can a plane fly upside down?” This bugged him as a kid, and when he got frustrated and pestered his teach about it, he was told,
“Shut up Raskin!”
Eventually he learned enough math to verify for himself that the Bernoulli effect doesn’t cut it, that it doesn’t account for all the lift needed to make a plane fly.
Read this excerpt from one of his articles and you’ll see it gets pretty complicated. It’s a taste of his explanation for why the Bernoulli equation doesn’t account for how a wing creates lift:
