William Jones and his Circle: The Man who invented Pi. In 1706 a little-known mathematics teacher named William Jones first used a symbol to represent the platonic concept of pi, an ideal that in numerical terms can be approached, but never reached.
Pi is known as an irrational number. When calculated, its decimal places are unending, and the numbers have no pattern of repetition. Therefore, it cannot be described as a ratio of two integers. The ancient Greek mathematician Archimedes is believed to be the first to calculate pi, which bears the same symbol as the 16th letter of the Greek alphabet.
