We might not write our dates as “month. day. year” as they do in North America, so to us it’s only 14.3.16 – but that doesn’t mean we can’t celebrate the brilliantness and fun that is Pi day.

The mathematical constant Pi is the ratio of a circle’s circumference to it’s diameter, but there’s so much more to know. *Did you know:* that it has been calculated to over one trillion digits past its decimal?

Pi is an irrational number, which means it is infinite and non-repeating – so it can be some good geeky fun to challenge yourself (or your friends) to memorise as many digits as you can. However, only 39 digits past the decimal are needed for accurate calculations.

Strangely enough the Pi, in Raspberry Pi (one of our favourite platforms here at Maker Workshop) is not named after the mathematical constant, rather Raspberry comes from the tradition of naming computer companies after fruit (Apple and Apricot are two examples) and Pi was originally because it was to only run Python code; however, as it now runs a full Linux distribution, it can run Python but also C/C++, Java and many other languages. And as someone pointed out the name ‘Kumquat Ja’ just isn’t as enticing.
