A group of MIT undergraduates is searching for tetrahedra that tile space, the latest effort in a millennia-long inquiry. They’ve already made a new discovery.

Four mathematicians have cataloged all the tetrahedra with rational angles, resolving a question about basic geometric shapes using techniques from number theory.

The relationships among the properties of flexible shapes have fascinated mathematicians for centuries.

Christine Darden worked at NASA for 40 years, helping make supersonic planes quieter and forging a path for women to follow in her footsteps.

Long considered solved, David Hilbert’s question about seventh-degree polynomials is leading researchers to a new web of mathematical connections.

Imagine if we lived on a cube-shaped Earth. How would you find the shortest path around the world?

Two teams found different ways for quantum computers to process nonlinear systems by first disguising them as linear ones.

A number theorist recalls his first encounter with the Riemann hypothesis and breaks down the math in a new Quanta video.
