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?
