Agulha de Buffon e o número Pi

Features Agulha de Buffon e o número Pi

This app features a mathematical experiment known as the Buffon needle.
It is a classic problem of geometric probability, where a needle is dropped randomly in a region of uniformly spaced parallel lines.
This app simulates a simple case where the needle length is the distance between two adjacent parallel lines.
Let N be the total number of needles thrown at a given time; let C be the number of needles crossing the lines.
Let R = 2 × N ÷ C.
R is an approximation of Pi ( π).
In this app, the user can change the number of needles dropped at each tap and the number of threads in the target region.
