Around 250 B.C., the Greek mathematician Archimedes calculated the ratio of a circle's circumference to its diameter. A precise determination of pi, as we know this ratio today, had long been of ...

The Archimedes ran RISC OS, a very nice graphical operating system written explicitly for the ARM architecture. RISC OS is now available for the Raspberry Pi, finally bridging the gap between ...

Archimedes determined the upper and lower range of pi by finding the perimeters of inscribed and circumscribed polygons. By doubling the number of sides of the hexagon to a 12-sided polygon ...

Archimedes is the attested author of the first rigorous definition of pi, which he did by way of geometry, using polygons ...

Pi Day is Friday, March 14. The relatively new holiday is a celebration of the mathematical calculation pi, or the infinite number representing the constant ratio of a circle’s circumference to its ...
