Pi can calculate the circumference of a circle by measuring the diameter — the distance straight across the circle’s middle — and multiplying that by the 3.14-plus number.

Here's what to know as math lovers around the world mark Pi Day. Pi Day was first celebrated in 1988 at San Francisco's Exploratorium, a museum of science and technology that encourages visitors ...

Despite this difficulty, over the past 300 years, mathematicians have established different proofs of pi's irrationality, using techniques from across mathematics.

March 14—aka Pi Day—isn’t just for math nerds. It’s the one day a year where we celebrate the magic of the number π (pi), which starts at 3.14 and goes on forever.

In 'Math for English Majors,' Ben Orlin says celebrating Pi Day on March 14 is mathematically wrong. It should be July 22.

On a number line, if you pin up 3.14, pi, and 22/7, pi is just ever so slightly closer to 22/7 than to 3.14, making the fraction the superior approximation. Ben Orlin / Black Dog & Leventhal ...
