From crumpled paper to termite mounds to three-sided coins, L. Mahadevan has turned the whole world into his laboratory.

The p-adics form an infinite collection of number systems based on prime numbers. They’re at the heart of modern number theory.

Have fun exploring a numerical puzzle, a geometric puzzle and a game of random patterns, all inspired by the playful genius of the legendary mathematician.

After 44 years, there’s finally a better way to find approximate solutions to the notoriously difficult traveling salesperson problem.

A small community of mathematicians is using a software program called Lean to build a new digital repository. They hope it represents the future of their field.

Despite recent progress on the notorious Collatz conjecture, we still don’t know whether a number can escape its infinite loop.

Computer scientists are trying to build an AI system that can win a gold medal at the world’s premier math competition.

Two computer scientists found — in the unlikeliest of places — just the idea they needed to make a big leap in graph theory.

Mathematicians have long grappled with the reality that some problems just don’t have solutions.
