About:
As you might know, the word "pi" indicates an irrational number, with no repeating/repeating decimals. It can be dated back to being the 16th letter of the Greek alphabet. In geometrical terms, it is the ratio of a circumference of a circle to it's diameter. But above all, most people know of it as the mathematical term, 3.14. Of course, that may be but the simplified form you see on a calculator, yet how exactly did this infinite number come into play?
