The mathematically inclined geek will appreciate this graphic expression of Pi as the number 3.1415926... wrapped in the shape of the mathematical symbol for Pi!

Pi is a mathematical constant which represents the ratio of any circle's circumference to it's diameter. When a circle's diameter is 1, it's circumference is Pi!

This t-shirt is black in colour and features the most revered mathematical constant in the known universe!

Have fun memorising!
