#### 14 March is the day of birth of Albert Einstein, who was awarded the Nobel Prize. Yet, today has established as the International Day of Constant pi.

As with many irrational numbers, pi’s digits are random and endless.

This has some interesting philosophical implications – see Borges’ “Library of Babel” (http://en.wikipedia.org/wiki/The_Libr…) and Pickover’s “We are in the Digits of Pi and Live Forever” (http://sprott.physics.wisc.edu/pickov…).

Of course, it all rests on the assumption that pi is normal (in the mathematical sense). That any number is normal is still unresolved, but the digits of pi we have so far give us reason to assume it is.
