In this thesis, we present the story of the number pi. The first breakthrough in the calculation of its digits was made by Archimedes. The story gains new dimensions with the invention of infinitesimal calculus in the 17th century and reaches its climax with the discovery of Chudnovsky formula. This formula presents us with the world of elliptic and hypergeometric functions, and of complex multiplication. The correctness of the implementation can be verified with the BBP formula. We finish by using hypergeometric series to generate series for other constants, which is made possible by Zeilberger's algorithm.
