In 1882 the german mathematician Ferdinand Lindemann showed that pi is a transcendental number http://en.wikipedia.org/wiki/Transcendental_number

Such numbers have an infinitesimal decimal expansion with no periodicity in the numbers.

It has been said that the decimalexpansion of pi is the perfect generator of random numbers.

The record is ten million decimals generated with a computer using the Taylor-series expansion of arcustangens π/4 =1 and then solving for pi.

Perhaps the strangest quality of pi is that it surfaces in many areas of science other than geometry.

Probability calculus, imaginary numbers, infinitesimal series, calculus e.g..

So in the infinite number of decimals of pi are hidden the answers to many scientific enigmas. http://en.wikipedia.org/wiki/Pi
