In this simulation, 66 of the 100 needles crossed a line (you can count ’em). Using this number, we get a value of pi at 3.0303—which is not 3.14—but it's not terrible for just 100 needles. With ...

The proof resolves a nearly 80-year-old problem known as the Duffin-Schaeffer conjecture. In doing so, it provides a final answer to a question that has preoccupied mathematicians since ancient times: ...

What you’ll get is a pretty good estimate of the irrational number pi (3.14159...). To celebrate Pi Day this year, here are three ways to estimate pi using random chance that you can try out at home.

The ancient Greeks wondered when “irrational” numbers can be approximated by fractions. By proving the longstanding Duffin-Schaeffer conjecture, two mathematicians have provided a complete answer. The ...

Google's 2026 Doodle celebrates Pi Day by highlighting Archimedes' polygon method to approximate pi, marking the significance ...

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., ...
