Avi Wigderson and László Lovász won for their work developing complexity theory and graph theory, respectively, and for connecting the two fields.

Enter the world of perfect numbers and explore the mystery mathematicians have spent thousands of years trying to solve.

By harnessing randomness, a new algorithm achieves a fundamentally novel — and faster — way of performing one of the most basic computations in math and computer science.

A former graduate student reflects on how Isadore Singer, who died on February 11, brought together mathematicians, physicists and anyone else interested in the deeper connections between diverse fields.

A new thought experiment indicates that quantum mechanics doesn’t work without strange numbers that turn negative when squared.

In a second season of enlightened conversations, Steven Strogatz and leading researchers nourish our pandemic-starved minds.

To the surprise of experts in the field, a postdoctoral statistician has solved one of the most important problems in high-dimensional convex geometry.

A new proof demonstrates the power of arithmetic dynamics, an emerging discipline that combines insights from number theory and dynamical systems.
