Explore the Infinite World of Pi on Pi Day

Pi is an essential mathematical constant representing the ratio of a circle's circumference to its diameter. Pi is commonly approximated as 3.14159, but its decimal representation goes on infinitely without repeating.

To celebrate Pi Day on March 14th (3/14), we've compiled some interesting facts about pi:

  1. Pi is an irrational number, which means it cannot be expressed as a simple fraction and has an infinite number of decimal places.
  2. Pi has been studied for thousands of years, with the ancient Egyptians and Babylonians approximating its value.
  3. Pi has been calculated to be over 31 trillion digits, with the most recent record set in 2020.
  4. Pi is used in many areas of science and engineering, including calculating the circumference of circles, calculating the volume and surface area of spheres, and designing computer algorithms.
  5. Welsh mathematician William Jones first used the symbol for pi (π) in 1706, but it was popularized by the Swiss mathematician Leonhard Euler in the mid-1700s.
