In 1914, Indian mathematician Srinivasa Ramanujan published a short paper detailing several unusual formulas for calculating ...

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 ...

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 ...

For more than a century, Srinivasa Ramanujan’s uncanny formulas for the number pi have looked like pure mathematical ...

Most of us first hear about the irrational number π (pi)—rounded off as 3.14, with an infinite number of decimal digits—in school, where we learn about its use in the context of a circle. More ...

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 ...
