Calculating pi with unprecedented accuracy has zero scientific usefulness. But as a show of computing muscle and a mathematical curiosity, it’s endlessly intriguing.
We need just a little more party hat…
It’s March 14, the day we irrationally celebrate the ratio of a circle’s circumference to its diameter. Here’s a roundup from our archive of what we know about pi.
Pi is at the center of all circles.
We know pi appears when we talk about circles. But it appears in many other places, too. Why, pi, why?

This Pi Day we should celebrate William Jones, the 18th century Welsh farm boy who named the mysterious number.
Mathematicians have long been revealing the beauty in the one of nature’s most mysterious numbers.
Pi has an interesting relationship with some other unique constants in mathematics.
On international Pi Day it’s time to look at Pi’s position in unique formula that’s praised much for its beauty in uniting several mathematical constants.
This “pi plate” shows some of the progress toward finding all the digits of pi.
On the occasion of Pi Day, a look at the history of calculating the actual, and increasingly exact, value of pi (π).
Would anyone like a slice of my π pie?
3/14 on the calendar approximates the first three digits of the mathematical constant π. Math nerds will celebrate with baked goods, but π is a deeper, nobler entity.
Let’s paint a picture of ‘pi’.
The number pi (π = 3.14159265358979323846…), unique among the pantheon of mathematical constants, captures the fascination of the public and professional mathematicians. Three years ago one of the authors…
Some people have argued that Pi’s days are numbered and that other tools, such as tau, could do its job more efficiently. As someone who has studied Pi throughout his entire working life, my response to…
