It was a surprise that when any circumference of a circle is divided by its diameter, the answer was always the same; the number we know know as Π. This was known many years BCE; but, it wasn't named then.

No one created pi; it's just there when calculating using our base 10 number system.

The first person to use the symbol Π for this number was William Jones in the eary 1700's. It became popular when Leonhard Euler, in the mid 1700's began to use it. (Euler was one of the greatest mathematicians of all times; and probably wrote more articles and books on mathematics than anyone else; so, when he began to use it, it came into standard use.)

Thanks for the history lesson Geno.

I think Euler is pronounce Oiler. Do you think that this is correct?

It is "Oiler," Melody......there remains a debate about who the greater mathematician was, Euler or Gauss. Euler was certainly more prolific in his output, even in his advanced years (when he was almost totally blind).....(I might throw Archimedes into the debate, as well !!!)
