This is the mathematical definition of pi.
Pi is the ratio between a circle's circumference and its diameter.

Not to be confused with Mizzou's own Dr. Banks, this English mathematician spent some 30 years calculating the first 707 digits of pi. Turns out he made an error after the 527th place :(

This Greek letter is used to represent two times pi.
Tau

This is another name for “the quantity which, when the diameter is multiplied by it, yields the circumference.” (It's obvious why they changed it, I hope.)

In 1888, a man from this state claimed to have supernaturally obtained the ability to exactly measure a circle and proposed to round pi to 3.2 through the state legislature to 'copywright' his findings. A math professor proved that his claims led to an obviously errant approximation for pi.

Known as the Diophantine approximation of Pi, this fraction gives a very crude approximation.

According to mathematicians, it is more accurate to say that circles have infinitely many of these rather than none, owing to its relationship to pi.
