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 ...

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

Ramanujan's pi-computing machinery exactly mirrors the necessary structure in modern physical theories (LCFTs).

Why did Ramanujan’s formulae stay relevant for a century? His set of 17 expressions offered huge speed. They gave long digit ...

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 ...

Math teacher Marcus Hung squinted in mock concentration. "3.1415," he said before pausing dramatically and then smiling. "That's about it." Reciting the digits of the irrational number pi is not his ...

In 1914, Indian mathematician Srinivasa Ramanujan made public a collection of 17 mathematical expressions for calculating pi, an iconic constant used worldwide. These formulations, compact yet highly ...
