Maybe no one in your social circle can.
While taking King’s Pilot School class I was taught that Bernoulli’s Principal explains how planes generate lift. But a few months later I saw someone post online who said that it is actually debated whether this is true. I thought it was interesting and have been thinking about it lately. A little research found this article in Scientific American which describes the ongoing debate.
And why do you have to be so rude?
I get annoyed at clickbait titles.
It’s quite obvious Bernouilli’s theorem is largely correct, even though it does not cover the entirety of why air behaves like this.
Planes stay in the air because of aerodynamic lift. Planes are designed around this principle and thousands of planes stay in the air because we know this is how it works.
To be clear I have no idea either way.
Is this one of those “we know what the principle is (aerodynamic lift) and how to make it work but we don’t know why it works the way it does?”

No, we know why. There are just certain peculiarities that cannot be explained by the existing theories.
Maybe I’m misunderstanding some nuance here but it sounds like you’re saying exactly what the person you replied to said.
The article is much less about the principle, because even it says it is scientifically true. The focus of the article is “we can’t explain it, man!” It’s a really long “how do magnets work” piece.

Oh boy, you’re going to be really surprised when you learn how steel ships float.
Wing diverts air down
Newton’s 3rd law means wing goes up
That is not, in fact, how aerodynamic lift works.
Sure it is.
It’s really not. The longer travel of the air over the top of the wing creates an area of lower pressure than the air flowing under the wing, effectively “pushing” the wing upward.
That is true, yes. The shape of the wing creates a pressure gradient, causing the wing to lift up and deflect the air down. Newton’s law requires an equal and opposite force.
This spoon in the sink illustration really shows this:

Because it is clickbate we know the general principles as to why aircraft work but not 100%.
It is like saying you don’t know how a week works because you can’t tell me what day Dinsdag is.
Doesn’t really matter how high quality the piece is. The title is too clickbaity. Everyone here on Lemmy is here because we fled shitty internet practices at some point, so we’re fairly sensitive to things like sensational wording. I’m guessing most downvoters did not click the link.
