Pi Day 2022- History, Aim and More

Every year on 14th march celebrate the pi day,  Also known as pi, the first three and most recognized digits are 3.14.

Pi Day is when mathematicians and math lovers around the world celebrate pi, which is the ratio of a circle’s circumference to its diameter.

The circle is often the first shape many learn in childhood and can be observed in nature in pinecones, apples, oranges, the cornea in our eyes the circle is everywhere!

Since its discovery, pi has been used every day. Engineering, construction, GPS, simulation, radio, TV, telephones, power generation, motors all of this is possible thanks to the magic of pi.

Some historians even debate whether pi was used when the ancient Pyramids of Giza were constructed because the structures are nearly perfect geometrically.


The first calculation of pi was done by Archimedes of Syracuse (287-212), an ancient Greek mathematician and astronomer. He calculated the area of a circle with the use of the Pythagorean Theorem.

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.

David Chudnovsky, a mathematician who built his own supercomputer with his brother to explore the inner infinity of pi, sums up the power of pi rather eloquently.
