Ramanujan’s elegant formulas for calculating pi, developed more than a century ago, have unexpectedly resurfaced at the heart ...

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

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

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 ...

More than a hundred years ago, long before anyone imagined supercomputers or black hole simulations, legendary Indian ...
