| 3.14 and a little bit more... |
Every circle in the universe (including all those which have never been drawn or even imagined) contains within it one of the most fascinating numbers in the whole of Mathematics.
Whether you measure in inches, centimetres, kilometres, light years or even Martian Zargs it's always the same. Circumference divided by Diameter gives the same answer. We call that number Pi (
) .
The crazy thing about is that it goes on for ever. You can't ever write it all down and there is no repeating pattern. Even if all the atoms in the universe were converted into digits, there would still be digits left to write. Every phone number in the world is hidden in there somewhere, in fact every number sequence you name, any length you like, is there. Convert the digits into letters and you will find, somewhere along the digits, every book that's every been written. Convert the digits to notes and you will find every song and every symphony.
We only know a few trillion digits so far using the best computers available, but all we are doing is opening the window a little wider on something which goes on for ever and which has been there for ever.
Here are some great ways of finding out a bit more about Pi:
