#NationalPiDay
Pi is the ratio between the circumference of a circle and its diameter. While the idea of pi has been known for nearly 4000 years, accurately calculating it has been something of slightly more recent mathematical development. By 2000 BC, the Egyptians and Babylonians accurately used the constant to build. Mathematicians such as Archimedes, Fibonacci, François Viète, Adriaan van Roomen, and Gottfried Wilhelm Leibniz all calculated pi by various methods. However, in 1706, Welsh mathematician William Jones introduced the Greek letter π to represent the ratio of a circle's circumference; pi.
