Throwing Hotdogs to Calculate Pi's ValueThe web site tells it all. You actually can calculate an approximate value of pi by throwing a frozen hotdog. For those familiar with the history of mathematics, the hot dog experience is a slight variation of the Buffon Needle Experiment. What is needed:
Now, the calculation phase. Multiply the number of tosses by two and divide by the number of "line touches." For example, if the hot dog was thrown 200 times, and it crossed 128 times, the calculated value is (200 x 2)/128 = 3.125. Not a bad approximation for pi! On the CutTheKnot website, Scott Brodie provides a good overview of the history of the Buffon Needle Experiment and the related mathematics.
