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 ...

Pi Approximation Day 2023 is here! On this day, we celebrate the mathematical marvel known as Pi or 3.14. Pi is an irrational number, which means it can never be written as a fraction and has no end.

You might be familiar with the never-ending number π (pi), which is most relevant for studying circles. But you might not know much about the genius guy who first calculated pi: Archimedes of Syracuse ...

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., ...

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 ...

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, ...

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 ...
