A Random Walk with Pi | Weird Science | Scoop.it

This Figure exhibits a 100 million base 4 walk on π, where the color is coded by the number of returns to the point. The authors empirically tested the normality of its first roughly four trillion hexadecimal (base-16) digits using a Poisson process model, and concluded that, according to this test, it is “extraordinarily unlikely” that π is not 16-normal (of course, this result does not pretend to be a proof).
