(1) randomly plot points inside the unit square (2) some will fall within the unit circle The fraction of points inside the circle approaches π/4 as the number of points → ∞ (source: https://commons.wikimedia.org/wiki/File:Pi_30K.gif …)pic.twitter.com/7R08x6k3AN

Buffon's Needle Trick is my fav way of approximating π (1) draw parallel lines separated by the needles length (2) throw a bunch of needles in the air (& run) (3) the fraction of needles that cross a line → 2/π as # of needles → ∞ (source:http://mathgifs.blogspot.com/2013/11/buffons-needle-and-his-noodles.html …)pic.twitter.com/nlzbguepum
