2020-02-01 | No One Can Explain Why Planes Stay in the Air - Scientific American
'Air molecules flowing atop a wing do not behave like that, but Bernoulli’s theorem does not say why not. '
'Although it is a fact of experience that air moves faster across a curved surface, Bernoulli’s theorem alone does not explain why this is so. '
'This means that Bernoulli’s theorem alone is insufficient to explain these facts. '
'Nevertheless, there are several reasons that Bernoulli’s theorem does not by itself constitute a complete explanation of lift. '
'In other words, the theorem does not say how the higher velocity above the wing came about to begin with. '

That's a clickbait title there. The article basically says "there are more than one competing factions of scientists who have differing theories and ideas on how some aspects of flight work". It's not that we don't know why planes stay in the air, it's more that we don't have a 100% verified model that answers all questions about flight. This same thing is true for gravity, quantum physics, the origin of the universe and life itself. We may not have perfect models of any of those things, but we understand them enough to apply them and make use of them. You don't always have to have a full model of things in science in order to understand how to apply it. Flight is one of those things. We're doing fine with it after only about 100 years of doing it.

Is that not what the article said?
Obviously there is adequate understanding to apply it, but no complete understanding. We know bees fly but cannot mathematically explain it.

Yes that is essentially what the article said, but the title (OP didn't write the title, btw) made it sound like we have no understanding of the mechanics of flight at all. We have a great deal of understanding on how lift, drag, aerodynamics and fluid dynamics pertaining to flight works but we lack a 100% mathematical model for it. I took offence to the title because of that fact. It was just too sensational for what the contents actually said.

Well duh, obviously.
OP IS FAGGOT, after all.

OP is indeed a faggot. He made 79 submissions to /v/Canada and 64 submissions to /v/WinnipegJets. He probably voted for Trudeau as well.

Planes are TRANNIES!!!

If helicopter blades produce lift, is it because they push air downward, or is it because they produce a vacuum above the craft and the craft falls into the hole in the atmosphere above it?
