Personally I think pi, the ratio between the diameter of a circle and its circumference, is much more amazing, and appears in a much wider variety of places, but we all recognise it as 'part of the woodwork', so it's invisible.

Tell me of the wonder of Pi.

pi's pretty cool (and yes, that sounds extremely sad )

 

One of the most fasinating formulas associated with pi is this:

 

pi/4 = 1 - 1/3 + 1/5 - 1/7 + ...

 

Although it's not particularly efficient, it's quite incredible such a simple formula could lead to a value that mathematicians have been trying to obtain accurately over 2000 years.
