It's Pi Day

Pi Day is celebrated on March 14th (3/14) around the world. Pi (Greek letter “π”) is the symbol used in mathematics to represent a constant — the ratio of the circumference of a circle to its diameter — which is approximately 3.14159. Pi Day is an annual opportunity for math enthusiasts to recite the infinite digits of Pi, talk to their friends about math, and eat pie.

Today our pupils learnt about the origins of Pi and how to apply it to work out the diameter of a circle during Maths classes. The theme carried on to lunch, where we all ate Pi.

Pi has been calculated to be over 50 trillion digits beyond its decimal point. It will continue infinitely without repetition or pattern as an irrational and transcendental number. While only a handful of digits are needed for typical calculations, pi’s infinite nature makes it a fun challenge to memorise, and computationally calculate more and more numbers.
