The mystery of pi.

Hem … pi goes on forever because it’s an irrational number and can’t be expressed as a simple fraction. A circle is curved so it can’t be expressed in a finite number.

My maths is basic so I’m sure there will be better answers.

Ah, I see what you mean!

Yes, so with a straight line, for example, you have consistency, but a circle is kind of always getting away from you, so to speak.

Thank you, ArchaeC, you've summed it beautifully in one sentence. When I looked it up all I got was several mathematical proofs by various famous mathematicians which might as well have been in Chinese. Brilliant!

A circle is curved, so no matter its size, it’s constant, so the ratio between its circumference and diameter is represented by the same irrational number that has an indefinite number of digits. 

I’m afraid I’m at the limit of my maths knowledge with this one. All I know is that it is easier to express its value as pi rather than 3.14159 …

I appreciate your effort, ArchaeC, thanks,
