Pi Day Celebration: 8 Amazing Facts About the Number π

For centuries, Pi (π) has captivated mathematicians, scientists, and curious minds alike. Its infinite decimal expansion, its role in geometry, and its countless practical applications make it a truly remarkable number.

But what exactly is π? It’s a mathematical constant representing the ratio of a circle’s circumference to its diameter. In other words, it’s the distance around a circle divided by the distance from one side of the circle, through the centre, to the other side. Its approximate value is 3.142. This works for all circles because they are mathematically similar. For Pi Day, we have a list of 8 amazing facts about Pi for you.

• Pi is a never-ending number So far, pi has been calculated to 100 trillion digits, thanks to Google Cloud.

• Since the exact value of pi can never be calculated, we can never find the accurate area or circumference of a circle.

• Pi is the most recognised maths symbol in the world.

• People have been using pi for thousands of years. More than 4,000 years ago, the ancient Egyptians and Babylonians had figured out this constant and were using it to make calculations.

• Scientists use pi every day to make important calculations, such as determining the volume of a sphere, the area of a circle and the volume of a cylinder.

• If one billion digits of pi were printed on average it would go from NYC to the middle of Kansas.

• The calculation of pi is a stress test for a computer. Since it indicates the level of activity within the computer’s processor.

• Pi Day happens on March 14 is celebrated as Pi Day because 3.14 is the first digit of pi and it also happens to be Albert Einstein’s birthday.
