Pi in a Spiral ~ Math as Art Poster
- from our Affiliates
Here is a beautiful visual depiction of Pi, or π, is a mathematical constant, the ratio of a circle's circumference to its diameter, commonly approximated as 3.14159. It has been represented by the Greek letter "π" since the mid-18th century, though it is also sometimes spelled out as "pi". This depiction will be problematic for math experts, because the Pi pertains to circles, whereas this depicts it as a spiral, for purely artistic reasons.
