Pi goes on and on forever and never stops!  Nope!  Never!  There’s not even a pattern to the numbers (it’s irrational).  
This is not the kind you eat (sorry), but the mathematical pi.  
Pi is important in the measurement of circles.  (It’s the ratio of a circle’s circumference to its diameter AND the ratio of a circle's area to the square of its radius) and knowing that is very useful, for instance, in calculating what size tires to put on your car.

On March 14, 2004, Daniel Tammet set a new British and European record when he recited the number pi from memory to 22,514 decimal places in a time of 5 hours, 9 minutes, 24 seconds.  The event was organized by, and in aid of, the (British) National Society for Epilepsy, and took place at Oxford's Museum of the History of Science.
Daniel Tammet is a high-functioning autistic with savant syndrome.   He has astonishing mental skills which include the ability to visualize numbers in his head.  These abilities first emerged following epileptic seizures as a toddler. Daniel is one of only 25 documented savants in the world.  His bestselling 2006 memoir “Born On A Blue Day,” documents his life growing up and living with Asperger's syndrome and synesthesia, a condition which causes him to understand words and numbers as shapes, colors, textures and motions.
