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 ...

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, ...

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 ...

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 ...

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 ...

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 most people associate the mathematical constant π (pi) with arcs and circles, mathematicians are accustomed to seeing it in a variety of fields. But two University of Rochester scientists were ...
