Archimedes' value, however, was not only more accurate, it was the first theoretical, rather than measured, calculation of pi. How did he do it?

Although many sought to find it, the calculation of pi, which is also expressed by the fraction 22/7, is commonly credited to Greek mathematician Archimedes of Syracuse more than 2,200 years ago.

Archimedes' method of approximating π with polygons, and similar techniques developed in China and India, would be the dominant way mathematicians would approach the calculation of the digits π ...

Greek mathematician Archimedes of Syracuse calculated the infinite mathematical concept pi in the 200s BCE, which we celebrate annually on March 14, or Pi Day.

Archimedes' method finds an approximation of pi by determining the length of the perimeter of a polygon inscribed within a circle (which is less than the circumference of the circle) and the ...

An algorithm to calculate Pi on IBM’s quantum computers honors Pi Day—and helps us understand how a quantum computer works.

Bursts of calculations of even more digits of pi followed the adoption of iterative algorithms, which repeatedly build an updated value by using a calculation performed on the previous value.

It was first recorded by Archimedes, but you can replicate his discovery in all kinds of ways. Here's the pie version of Pi, the down, dirty and baked goods approach, illustrated by Brady Haran, a ...

Scientists have calculated the value of pi to one hundred trillion digits, but you don't have to be a mathematician to understand it.

In honor of Pi Day, we bring you a brief history of everyone's favorite irrational constant.

Saha and Sinha did not find the most efficient method for calculating pi, though. Other series have been known for several decades that provide an astonishingly accurate value much more quickly.
