Buffon’s Needling Ants
The classic probability experiment known as Buffon’s needle produces a statistical estimate of the value of pi, the ratio of a circle’s circumference to its diameter. The experiment consists of randomly dropping a needle over and over again onto a wooden floor made up of parallel planks. If the needle’s length is no greater than […]

Fractal Roots and Artful Math
The term “mathematical art” usually conjures up images of M.C. Escher’s endless staircases, Möbius-strip ants, and mind-boggling tilings. Or it might remind one of the intimate intertwining of mathematics and art during the Renaissance with the development of perspective painting and eye-teasing stagecraft. A view of the recent MathArt/ArtMath show at the Selby Gallery in […]
