Every year on March 14th we celebrate and this year on Friday March 14, 2025, we observe the unofficial National Pi(e) Day = 3.1415926535897932384626433832795 or 3.14 for short.
Pi is the ratio between the circumference of a circle and its diameter, accurately calculating it has been something of slightly mathematical development.
In 1706, Welsh mathematician William Jones introduced the Greek letter π to represent the ratio of a circle's circumference; Pi.
We can celebrate the National Pi Day by Throw a Pi party, and decorate with Pi symbols.
I want to wish to all friends and to everyone at ActiveRain community a Happy National Pi Day.
