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)
Humans Already Use Way, Way More Than 10 Percent of Their Brains - It’s a complex, constantly multi-tasking network of tissue—but the myth persists. - By now, perhaps you’ve seen the trailer for the new sci-fi thriller Lucy. It starts with a flurry of stylized special effects and Scarlett Johansson serving up a barrage of bad-guy beatings. Then comes Morgan Freeman, playing a professorial neuroscientist with the obligatory brown blazer, to deliver the film’s familiar premise to a full lecture hall: “It is estimated most human beings only use 10 percent of the brain’s capacity. Imagine if we could access 100 percent. Interesting things begin to happen.” Johansson as Lucy, who has been kidnapped and implanted with mysterious drugs, becomes a test case for those interesting things, which seem to include even more impressive beatings and apparently some kind of Matrix-esque time-warping skills. Of course, the idea that “you only use 10 percent of your brain” is, indeed, 100 hundred percent bogus. Why has this myth persisted for so long, and when is it finally going to die?

Team at T4T LAB imagine organic architectural environments
These striking renders by students at Texas A&M University’s Department of Architecture are great examples of experimental, abstract design environments. Some look almost finished while others are in early stages, but all show off a tremendous level of ambition and imagination. No doubt their inspiration came from natural structures as well as the sort of parametric ideology of architects such as Zaha.
