Pi Day is coming: Start planning your parties now (Source: Flickr)

If you love maths, prepare to π your pants with excitement.

In just over two weeks, there will be a once-in-a-century opportunity for maths lovers to geek-out on an ultra-special Pi Day.
Pi Day falls on March 14 every year and is so called because when written numerically it follows the first three digits of the mathematical constant π that allows us to work out the circumference, area and volume of round objects.
It is celebrated (predominantly in the US) as an annual chance to get kids excited about the subject.
This year however, Pi Day will give us a whole 10 digits when we reach 3/14/15 at 9:26:53 in the morning.
One mathematician, Jeffery S Rosenthal, argues that it can be taken even further, claiming all of the infinite digits of π could be reached on a single point in time on that date.
I thus propose that March 14, 2015, at 9:26:53.58979... (i.e., at 26 minutes and 53.58979... seconds after 9 o'clock a.m., where the remaining digits of 53.58979... all follow the digits of pi) be designated and celebrated as Pi Instant, the single instant when all of pi's infinite digits are all laid out before us. Start planning your parties now!
You don't need to tell us twice.
