Pi Day 2008

Pi – An irrational constant used to represent the ratio between a circle’s circumference and its diameter, symbolised by the greek letter Pi, approximately 3.14159265358979323846264338327 (not rounded)

Pi Day – A geek holiday held to celebrate the mathematical constant Pi, observed on March 14 (3/14 in the American date format)

We celebrated Pi Day 2008 in style. My Maths class were particularly excited about it, and I’d brought in some pies and cakes and other circular food, as well as a half-moon cake (because there are Pi radians in half a circle) and we did some hardcore integration involving Pi (not just for fun, it was on the course) and then paraded Pi around and took pictures!

We had a medley of the Pi Song (Mathematical Pi by Ken Ferrier and Antoni Chan) – the song can be downloaded from this page (I also recommend The Milk Song)

I know Pi to about 35 decimal places, thanks to the song (plus a few extra digits). The record is 100,000, which is pretty crazy. Pi presents us with the most incredible concept; the fact that its decimal digits go on infinitely without any significant repeats, with no patterns emerging, it may as well be random. We have always wished to learn from Pi and discover its secrets. Maybe one day the numbers will be plotted on a graph in such a way that we will realise a connection with something in nature, space, the truth about life … who knows?
