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.

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 ...

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 ...

Ramanujan’s elegant formulas for calculating pi, developed more than a century ago, have unexpectedly resurfaced at the heart of modern physics. Researchers at IISc discovered that the same ...
