If you haven't seen the trailer for the new Star Trek movie, then check it out here.
There's a part where James T. Kirk jumps from a car and then stops himself from sliding off the edge of a cliff as the car goes flying off the edge. Apparently someone at Popular Science (one of my favorite magazines) went ahead and calculated whether or not it was possible for Kirk to do this. The nice folks on Gizmodo put together a pretty great video about all this. Pretty interesting.
