It’s the most wonderful time of the year—for mathematicians, anyway. Pi Day is Thursday, March 14. The relatively new holiday is a celebration of the mathematical calculation pi, or the infinite ...

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 ...

It’s the most wonderful time of the year—for mathematicians, anyway. Pi Day is Friday, March 14. The relatively new holiday is a celebration of the mathematical calculation pi, or the infinite number ...

March 14 is Pi Day in the US, as the date matches the first three digits of the famous number. On Pi Day 2015, Google announced that a researcher had uncovered the first 31 trillion digits of pi, ...

Today is March 14, or "3/14," the first three digits of Pi. It's a day celebrated around the (geek) world as "Pi Day." Pi, of course, is the ratio of the circumference to the diameter of a circle. It ...

The number represented by pi (π) is used in calculations whenever something round (or nearly so) is involved, such as for circles, spheres, cylinders, cones and ellipses. Its value is necessary to ...

An algorithm to calculate Pi on IBM’s quantum computers honors Pi Day—and helps us understand how a quantum computer works. Ever since Archimedes hit upon a value for Pi in the third century B.C., ...

Everybody knows the value of pi is 3.14…er, something, but how many people know where the ratio came from? Actually, the ratio came from nature—it’s the ratio between the circumference of a circle and ...

Pi, a mathematical constant denoted by the Greek letter π, is the ratio of a circle's circumference C to its diameter d: π = C/d. The circumference of a circle is, in turn, equal to 2πr, where r is ...

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 perimeter ...
