What's up in

A numerical puzzle, a geometric puzzle and a game of random patterns — all with connections to the legendary mathematician — elicited an enthusiastic response from readers.

Struggling with math problems that can’t be solved helps us better understand the ones we can.

Bryna Kra searches for the patterns in sequences of numbers that explain how complicated dynamical systems evolve over time.

For almost a century, the anonymous members of Nicolas Bourbaki have written books intended as pure expressions of mathematical thought.

David Conlon and Asaf Ferber have raised the lower bound for multicolor “Ramsey numbers,” which quantify how big graphs can get before patterns inevitably emerge.

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.

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.
