Airspeed Velocity of a Swallow

At first I was pleased when I ran across this fascinating paper that determined the answer to the penultimate geek question (the ultimate being "42"). Perhaps in comparison, I'm not that big of a geek, but then it occurred to me that the fact that I found this and thought it was way cool, makes me an even bigger geek! Ah well, nothing I didn't already know. (The reason I was looking in the first place.)
