Today is pi day! No, that’s not a typo, it’s a reference to the mathematical term.
The date is 14th March, which can be written as 3/14, and is the first three digits of this amazing irrational number.
Many of us would have only come across pi during maths lessons, and probably haven’t come across it since. (Just to re-jig your memory, the circumference of a circle is two x pi x radius; and the area is pi x radius-squared – I bet your probably remembering any horrid maths teachers that you had instead of the numerical theory!)
But the number plays an important role in the field of irrational numbers, which are numbers that have a never-ending stream of digits, and without a pattern emerging amongst them.
This Pi-Search website allows you to search for any string of digits within the first 200 million digits of Pi.
See if you can find your date of birth within this massive set of numbers. You’ll definitely be in a select few if you can’t! Alternatively, if you clicked on this link because you thought it was about pie, the dessert; let us know your favourite one!
