This is known as Buffon's needle problem, after the French mathematician Georges-Louis Leclerc, Comte DE Buffon, who first proposed it in 1733.
这就是著名的蒲丰针问题，由法国数学家乔治·路易·勒克莱尔蒲丰伯爵在1733年第一次提出。
Ren Delin had extended it to long needle problem, who cancelled the limitation (the diameter of the convex domain is less than the distance of the grid of parallel lines).
任德麟作了进一步推广，即取消凸域直径不超过带域间距离这一限制。
