An interesting

point: To the best scientific guesses we have, the

Universe .. Everything, ;-) .. shouldn't be more than a few

Googol (10^100)

kilometers wide, and it's probably a

sphere or

hypersphere. So you would use

Pi to calculate its

area or how much stuff is inside of it.

The thing is that to calculate anything to a

Googol with

significant digits, you only need 100 digits of Pi. So we could calculate the number of

quarks (small

atomic particles) in the entire

Universe with, giving ourselves a thousand times more head-room than we think we need, 100,000 digits of Pi.

Here is the first 119,000 digits of Pi. Just

imagine - with this number we could calculate

perfectly the amount of atomic particles in

Creation, if we had

Its diameter (or some related precise measurement).

So, if this is the case, why do we have

supercomputers working at this minute on Pi's digits well into the Billions? And why do people have it memorized to all those digits?
