I remember being taught that Bernoulli's principle causes lift. I was skeptical—how does the air on top know to reach the other end at the same time as the air at the bottom? I think I did ask, and I was just told this is how it works, and that's the correct answer for the exam. This was before the internet, and I couldn't just look up the correct explanation.

I parked it in my brain as something I didn't really understand and forgot about it. This was until not so many years ago when I found a satisfactory answer on YouTube. It was criminal to have been raised in an era without the internet.
