Why did the ancients invent increasingly subtle and ingenious methods to arrive at an exact value of p? Human curiosity.
How do you find the holy grail of mathematics?
You start with a circle, which is the easiest geometric shape to draw (just fix one end of a string in place and swing the other end around it, inscribing a circle). Then measure the circle’s perimeter (also known as the circumference) and the distance across its widest point (the diameter). Divide the circumference by the diameter—and you have that well-known but eternally daunting number,
That is part of the mystique of
