Happy Pi Day

Internation Day of Mathematics – March 14th (Also know as 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 maths enthusiasts to recite the infinite digits of Pi, talk to their friends about maths, and eat pie.

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

What is Pi?

Pi (π) is the ratio of a circle’s circumference to its diameter.  The diameter of a circle is the distance from edge to edge, through the centre, and the circumference is the distance around the circle.

After measuring circular objects for thousands of years, it has always been determined that a circle is a little more than 3 times its width around (3.14), and because pi is a ‘constant number’, it will always be the same for any circle of any size.
