In the 18th century, French philosopher Georges-Louis Leclerc, Comte de Buffon determined that you can approximate pi by dropping needles on a grid of parallel lines (whose spacing is greater than the length of a needle) and calculating the probability that they will cross a line. The probability is directly related to pi.
Using this app, you can perform this experiment without the hassle of preparing sticks of equal length, surface marker, tape measure, etc. Drop the sticks with a tap and see how close you get to pi!
