Pi, is a non-repeating, never-ending decimal that is the circumference of a circle divided by its diameter. Recently, the number came to my attention when I read the book Born on a Blue Day, Daniel Tammet's autobiography about his life with Asperger's and synaesthesia. If you have 10 minutes watch this fascinating video where he calculates Pi to 22,500 decimal places.
