PI (3.14159265359....) is an infinitely complex arrangement of digits,
each, in the long run, no more likely to turn up than any other digit.
Yet PI can be completely defined by :
PI/4 = 1 - 1/3 + 1/5 - 1/7 + 1/9 - 1/11 + ······
An infinite object expressed by a finite number of symbols.
A small finite number of symbols, but an infinite number of terms.
