Yesterday was 14th March. on a DD.MM format yesterday’s date is written as 3.14. There lies the connection with Pi. The Pi day as it is called is a celebration of this mathematical constant which  is the ratio of the circumference of a circle to its diameter. The value of Pi is 3.1415…… apparently you can compute to almost a trillion decimal points.

It has been represented by the Greek letter “π“. Popularly known as the transcendental number  meaning , it is not a root of a non-zero polynomial equation with rational coefficients. Ok its getting into rocket science realm. How this mathematical constant evolved should be seen in these video and how over tens of thousands of years several curious human mind went after solving this to the greatest decimal and the work is still on.
