Most people first learn about the number π (pi) in school, usually when studying circles. It is often written as 3.14, but this is just an approximation. In reality, pi is an irrational number, ...

Pi Day is upon us again, for those who note today’s date in the format 3/14 (March 14). But rather than talk about Pi Day itself, as I did last year, this year I want to talk about Pi and mathematical ...

Two scientists were surprised to find pi lurking in a quantum mechanics formula for the energy states of the hydrogen atom. “We didn’t just find pi,” says Tamar Friedmann, a visiting assistant ...

Most of us first hear about the irrational number π (pi)—rounded off as 3.14, with an infinite number of decimal digits—in school, where we learn about its use in the context of a circle. More ...

In 1655 the English mathematician John Wallis published a book in which he derived a formula for pi as the product of an infinite series of ratios. Now researchers from the University of Rochester, in ...

There’s a formula for pi, so why not for pie (pizza pie)? Pizza–of which the round kind has an area of pi times radius squared–is among the world’s most beloved foods. Yet what constitutes pizza ...

The "Pi in the Sky" math challenge gives students a chance to take part in recent discoveries and upcoming celestial events, all while using math and pi just like NASA scientists and engineers. In ...

While building a simpler model for particle interactions, scientists made a sleek new pi. Representations of pi help scientists use values close to real life without storing a million digits. The ...
