The famous mathematical ratio, estimated to more than 22 trillion digits (and counting), is the perfect symbol for our species’ long effort to tame infinity. By Steven Strogatz This article, ...

Pi, a mathematical constant denoted by the Greek letter π, is the ratio of a circle's circumference C to its diameter d: π = C/d. The circumference of a circle is, in turn, equal to 2πr, where r is ...

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 ...

A smarter way to find π using fake circles. This short shows a clever geometric idea that estimates pi without perfect circles, revealing why the method works and how approximation can beat precision.

Imagine a cup of tea. Wrap a piece of string around the circumference of the cup, and measure the length of the string. Then, lay your spoon on top of the cup, making sure it lies across the center of ...
