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 ...

Celebrate Pi Day and read about how this number pops up across math and science on our special Pi Day page. For more than two millennia, mathematicians have produced a growing heap of pi equations in ...

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 ...

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 ...

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 ...

Math enthusiasts around the world, from college kids to rocket scientists, celebrate Pi Day on Thursday, which is March 14 or 3/14 — the first three digits of an infinite number with many practical ...

In new research, physicists uses 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 ...
