**As today is National Pi Day, what better time to remind you of some the magnificent mathematical resources we have at the Library?**

Aside from all the books and journals we have on the topic down on Level 1 and online, we have access to a host of mathematical databases, including MathWorld – the web’s most extensive mathematics resource – and PlanetMath, a collaborative virtual community which aims to help make mathematical knowledge more accessible.

If numbers aren’t quite your thing and you’d like a quirkier interpretation of the theme, why not pop up to our Leisure Reading Collection on Level 4 and borrow a copy of Yann Martel’s Booker Prize winning *The Life of Pi*?

*Pi Day* is celebrated on March 14th 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 has been calculated to over one 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 memorize, and to computationally calculate more and more digits.
