Buffon's needle

释义

Buffon's needle

Suppose that a needle of length l is dropped at random onto a set of parallel lines a distance d apart, where l < d. The probability that the needle lands crossing one of the lines can be shown to equal 2l/(πd). The experiment in which this is repeated many times to estimate the value of π is called Buffon's needle. It was proposed by Georges Louis Leclerc, Comte de Buffon (1707–88).
