Buffon's Needle

Buffon's Needle

This applet provides a simulation of Buffon's Needle experiement.  A needle of length 1 being dropped at random on a floor covered with boards of width 1. Users can drop 1, 2, 10, or 20 needles.  Blue needles do not cross the crack between two boards; red needles do.  If X represents the ratio of crossings to attempts, then 2/X should approach a familiar number, Pi.
