The Year in Math and Computer Science
Even as mathematicians and computer scientists proved big results in computational complexity, number theory and geometry, computers proved themselves increasingly indispensable in mathematics.
A Scientist Who Delights in the Mundane
From crumpled paper to termite mounds to three-sided coins, L. Mahadevan has turned the whole world into his laboratory.
Building the Mathematical Library of the Future
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.
When Math Gets Impossibly Hard
Mathematicians have long grappled with the reality that some problems just don’t have solutions.
Conducting the Mathematical Orchestra From the Middle
Emily Riehl is rewriting the foundations of higher category theory while also working to make mathematics more inclusive.
How Physics Found a Geometric Structure for Math to Play With
Symplectic geometry is a relatively new field with implications for much of modern mathematics. Here’s what it’s all about.
New Geometric Perspective Cracks Old Problem About Rectangles
While locked down due to COVID-19, Joshua Greene and Andrew Lobb figured out how to prove a version of the “rectangular peg problem.”
In a Single Measure, Invariants Capture the Essence of Math Objects
To distinguish between fundamentally different objects, mathematicians turn to invariants that encode the objects’ essential features.
Graduate Student Solves Decades-Old Conway Knot Problem
It took Lisa Piccirillo less than a week to answer a long-standing question about a strange knot discovered over half a century ago by the legendary John Conway.
