# Pointless Pi or mesmerising maths?

International Pi day was held on March 14 – when thousands of people around the world celebrated this number that never ends.

If you are the same generation as myself, you will probably remember the first few digits – 3.14159 – and have a brief memory of using it in your maths lessons to work out either the circumference or diameter of a circle.

However, for some, learning a mind-blowing amount of the numbers in Pi has become a kind of mathematical sport, with reports of people reciting up to 40,000 digits or more. How on earth does anyone even check they are saying the right numbers!?

According to the Pi day website: “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.”

Pi is obviously a fascinating concept, with many mathematicians and scientists trying to work out if it has an even larger significance.

Its symbol (the Greek letter π) has also helped to make this number become quite a fun and popular part of maths.

So, are you a Pi fan or would you rather eat a lovely steak and kidney pie than sit around memorising ‘pointless’ numbers? Since I am not very good with numbers, I think I’ll stick to the edible variety myself, although I might be tempted to wear a Pi t-shirt, just to make me look intelligent!
