**Did You Know - Page 05: **What is Pi? Why is it celebrated?

**•**Maths enthusiasts, assemble! a little bit of learning and a whole lot of fun awaits on March 14, which is celebrated as Pi Day.

**What is pi?**

When you take the circumference of any circle and divide it by its diameter, you always get a value approximately equal to 3.14. Being an irrational number, the digits after the decimal point go on forever, starting with 3.1415926535... This unique number is called ‘pi’, written with the Greek letter 𝝅. Since this number is always the same no matter what the size of the circle, it is one of the most famous constants in Maths. Pi is immensely useful in many areas including Maths, Science, Astronomy, Architecture, Construction, and Engineering.

**Why March 14?**

March 14 was chosen as Pi Day because it can be written as 3-14, which looks like 3.14. Physicist Larry Shaw organised the first Pi Day celebrations at San Francisco's Exploratorium Science Museum in 1988.

Several fun traditions are followed to celebrate the day, and many of them involve pies. ‘Pie’ sounds like ‘pi’, so no surprises there! Pie-eating contests, pie-bake sales, discounts on pies, pie potluck parties, and so on... there's no end to the possibilities, just like there's no end to pi itself.
