Most of us can recall Pi to four or five digits, thanks to high school math, but now a team of Swiss scientists has broken the world record for calculating the mathematical constant. It took three and ...

Today is Pi Day, an annual celebration of the famous mathematical concept that has fascinated people for millenia. But what exactly is π (pronounced like the word "pie"), and where did the concept ...

Rather than a typical post for Pi Day (3-14, get it?) celebrating the wondrous properties of this mystical number π = 3.141592653..., I thought I'd tell you about how π could play a role in combatting ...
