I'm tired of this headline, its an oversimplification. We absolutely DO understand how and why they stay in the air, we just don't have the hard numbers behind

- FabHK 7y ago> We absolutely DO understand how and why they stay in the air, we just don't have the hard numbers behind it. The article claims the opposite: we do have the hard numbers behind it (we can predict how a wing behaves), but we don't have a good conceptual explanation for it at a layman's level (the how and why, if you so will).
- nimish 7y agoWe have a very good explanation for experts though. It turns out lift is really damn hard to explain since fluids are quite complicated. There's no reason to expect there's a layman's explanation at all, but you can make one from Newton's laws (Navier-Stokes -- conservation of momentum) and conservation of energy (Bernoulli) and conservation of mass (continuity equation) They are very complicated and the complexity is required to understand all the weird edge cases
