Includes a brief history, a page with different formulas and a list of references.

History, formulae, algorithms, programs, records of computation, and references.

Includes introduction on why people would want to calculate Pi, four methods for calculating it, over 8000 digits, poems and music.

An introduction to the number Pi and its history.

Clubs, links, memorizing technique, records, art, and programs.

Every sport has its championship. Every sport has its world ranking list. For many who like to memorize numbers, PI is the ultimate number, and it makes sense to create a list for people to get in touch and learn where they stand in the world of memorizers.

An article describing a potential link between two disparate mathematical fields-number theory and chaotic dynamics-that could lead to a proof that every digit of pi occurs with the same frequency.

An article by Charles Seife about how mathematicians slowly circle in on a proof that pi's unpredictable digits really are as random as they seem.

Provides generated pictures and personal signs out of digits of Pi. Also a Picture Gallery, PiSign, PiPhonie.

The concept of pi refers to the constant ratio of the diameter:circumference of any circle; irrespective of the number of degrees contained within that circle. An article in the "Science in Ancient Artwork"-Series by Charles William Johnson.
