A new study reveals that Srinivasa Ramanujan’s century-old formulas for calculating pi unexpectedly emerge within modern theories of critical phenomena, turbulence, and black holes. In school, many of ...

Mathematical formulas written over a hundred years ago could find an echo in the most current theories about black holes and ...

Most of us first hear about the irrational number π (pi)—rounded off as 3.14, with an infinite number of decimal digits—in ...

More than a century after Srinivasa Ramanujan scribbled his lightning-fast formulas for π in a notebook, physicists are ...

Discover how Ramanujan's century-old pi formulas connect to modern cosmology and turbulent fluid physics in groundbreaking ...

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, in a surprise discovery, have found ...
