Biography

Today we use the Greek letter pi as to denote the ratio of the circumference of a circle to its diameter.  But it was not always represented that way.  At one time it was designated by the letter E at other times as a ratio of single letters such as pi/delta.  Presumably this last notation suggests a ratio where the pi designates the circumference and the delta designates the diameter.  The ratio of the circumference to the diameter of a circle was introduced as the single letter π in a treatise examining lengths of curves.
