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:
- Pi is an irrational number, which means it cannot be expressed as a simple fraction and has an infinite number of decimal places.
- Pi has been studied for thousands of years, with the ancient Egyptians and Babylonians approximating its value.
- Pi has been calculated to be over 31 trillion digits, with the most recent record set in 2020.
- 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.
- 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.
