Disappointment to a noble soul is what cold water is to burning metal; it strengthens, tempers, intensifies, but never destroys it.
Wingtip vortices are a result of the finite length of a wing. Airplanes generate lift by having low-pressure air travelling over the top of the wing and higher pressure air along the bottom. If the wing were infinite, the two flows would remain separate. Instead, the high-pressure air from under the wing sneaks around the wingtip to reach the lower pressure region. This creates the vorticity that trails behind the aircraft. I was first introduced to the concept of wingtip vortices in my junior year during introductory fluid dynamics. As I recall, the concept was utterly bizarre and so difficult to wrap our heads around that everyone, including the TA, had trouble figuring out which way the vortices were supposed to spin. A few good photos and videos would have helped, I’m sure. (Photo credits: U.S. Coast Guard, S. Morris, Nat. Geo/BBC2)
cute story time: my one friend is dating a boy who is blind and they go for walks everyday and as they walk she describes everything to him and he always says that “she makes everything sound so beautiful, except herself, but one day I’m determined to make her describe herself in the same beautiful way she describes the earth” I’m so
there was a monarch butterfly outside with a torn wing and i thought it was dead so i went to pick it up off the ground with a flower but it began to hurriedly clutch onto it trying to drink something. it was totally trembling; it had a gash on it’s body and i knew it was dying but i couldn’t bring myself to kill it, so i googled a monarch’s favourite food and it ended up being mandarins. he literally devoured as much as he could before dying and i buried him outside my window.
You’re a good person
