The Infinite Life of Pi

[39 sec read]


Pi = circumference/diameter

The number π is a mathematical constant, the ratio of a circle’s circumference to its diameter.


Pi – Infinite number

It is an infinite number. In recent years, Pi has been calculated to over one trillion digits past its decimal.



The mathematician Archimedes used polygons with many sides to approximate circles and determined that Pi was approximately 22/7.


Leonhard Euler

The symbol (Greek letter “π”) was first used in 1706 by William Jones. A ‘p’ was chosen for ‘perimeter’ of circles, and the use of π became popular after it was adopted by the Swiss mathematician Leonhard Euler in 1737.


Number of decimals discovered over the years

Isaac Newton used infinite series to compute π to 15 digits, but the invention of computers accelarated the computation of the decimals of π.
