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)

"I firmly believe in small gestures: pay for their coffee, hold the door for strangers, over tip, smile or try to be kind even when you don’t feel like it, pay compliments, chase the kid’s runaway ball down the sidewalk and throw it back to him, try to be larger than you are— particularly when it’s difficult. People do notice, people appreciate. I appreciate it when it’s done to (for) me. Small gestures can be an effort, or actually go against our grain (“I’m not a big one for paying compliments…”), but the irony is that almost every time you make them, you feel better about yourself. For a moment life suddenly feels lighter, a bit more Gene Kelly dancing in the rain."
