Divide any circle’s circumference by its diameter and you get pi. But what, exactly, are its digits? Measuring physical ...

For the 30th anniversary of Pi Day, Google went there. It made a Pi-themed Google Doodle out of, yep you guess it, pie ingredients. Hilarious. SEE ALSO: Virginia Woolf gets a Google Doodle of her own ...

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 ...

Uncover the surprising connection between Ramanujan's pi formulas and the universe. Learn how his century-old math helps explain turbulence, black holes, and more.

Katie has a PhD in maths, specializing in the intersection of dynamical systems and number theory. She reports on topics from maths and history to society and animals. Katie has a PhD in maths, ...

For more than a century, Srinivasa Ramanujan’s uncanny formulas for the number pi have looked like pure mathematical fireworks, dazzling but detached from the physical world. Now a new wave of ...

Science often isn’t a bold “Eureka!,” a shout that that is loudly proclaimed after decades of painstaking research. Rather, many times, it begins with a “Huh, that’s funny,” and it ends someplace ...

A nearly 400 year-old formula for pi has been spotted in a quantum-mechanics formula for the energy states of the hydrogen atom, according to researchers in the US. Derived by English mathematician ...

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 ...

Physicists are now using principles from quantum mechanics to build a new model of the abstract concept of pi. Or, more accurately, they built a new model that happens to include a great new ...
