fuckyeahfluiddynamics:

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 have several done years of RPing, and this has taken me to countless different forums and, if you are at all familiar with RP forums, let me tell you, they were the lowest of the low some six or seven years ago.

In one of these forums, a legendary tale happened, a tale that, if I can ever recommend one thing to you, it is this:

The Ballad of Edgardo.

A story that happened to an anonymous RPer years ago.

Anyone will be able to appreciate it (and trust me, you will), but if you are kinsmen or kinswomen to me, if you ever had to experience the shittiest of RP forums and their terrible userbases, particularly that one guy that does whatever he wants and is an asshole that clearly godmods but gets away with it because the actual mods don’t give a damn, you will find the beauty behind the ballad that much brighter.

Just trust me on this one. It’s not a particularly long read, either.

I hope you enjoy The Ballad of Edgardo
