The Physics of How Bird Wings Work
Destin from Smarter Every Day explores one of those things we’ve all seen, but perhaps never fully understood. Just like the wing of an airplane, a bird’s wing (in this case a macaw) relies on creating higher pressure underneath than above the wing to create lift. You just will…not…believe…how they do it. That evolution refined such an intricate structure tens of millions of years ago, that’s enough wonder to last me the rest of the day.
You’ll never look at a bird the same way again.
