- Pi was first approximated by the Babylonians and the ancient Egyptians. However, Archimedes of Syracuse was the first to calculate it by using polygons in a circle to find a closer approximation.
- The symbol we use for pi today was introduced by William Jones in 1706 but popularized by Leonhard Euler in 1737.
- Pi is now used by mathematicians all over the world. Ithas over 1,000,000,000 digits calculated so far!
