That made my head hurt. All you have to do is remember one thing: Shoot something with a shotgun and get some Pi later. 
(Or do you consider that two things?) |

My opinion of Quebecois went up with that one. Those guys figured out how to get the Canadian government to subsidize their shotgunning.

I misread the article the first time. That's a fair way to estimate pi.
Consider a square with side of length B with a circle of diameter B drawn inside. The area of the square with the circular area removed is B^2. The area of the circle is pi(B^2)/4. Their ratio reduces to 4/pi. Example with B = 7 inches - The circle's area is 38.48451 in^2. The square is 49 in^2. 49 / 38.483451 = 1.27327 = 4 / pi exactly. Another way to approximate pi by this method is to shoot at a circle with a diameter drawn. Count the number of pellets on the diameter and the circumference. Divide the number of pellets on the circumference by the number on the diameter to find the value of pi from its fundamental definition. The interesting experiment would be to count pellets from one shot, then two shots, and so on until you're tired of counting little holes, and watch the approximation converge on pi. |

Since my HP-41cx doesn't work anymore, I could e-mail my buddy who still has Pi memorized out to 100 places. I think he only has e memorized out to 50 places, so I don't know what good he really is.
I did like their simplification for measuring with a unit diameter circle rolled one time. I tend to think in formulas and often forget the real world. Seems like getting an approximation from a turning wheel would be easier than a shotgun, but maybe not as fun (until you have to count the holes). |

Go to 50 seconds in to see S&T's girls soccer team take math seriously
And then at 2:30, student finishes reciting 791 digits of pi

22/7 isn't bad. The Mark of the Beast over the boiling point of water is even better.

So do you guys like your pi room temp or warmed up a la mode?
