The ancient study of an object’s curvature is guiding mathematicians toward a new understanding of simple equations.

The legendary graph isomorphism problem may be harder than a 2015 result seemed to suggest.

Can you turn a two-dimensional fractal into a 3-D object? Break out your scissors and tape for a chance to win a 3-D printed sculpture.

How do physicists reconstruct what really happened in a particle collision? Through calculations that are so challenging that, in some cases, they simply can’t be done. Yet.

The same problem that caused the 2007 financial crisis also tripped up the polling data ahead of this year’s presidential election.

When divvying something up, there's more than one way to define what's fair.

Mathematicians have had a hard time finding commonalities in large groups of random shapes — until recently.
