A new paper claims that a common digital security system could be tweaked to withstand attacks even from a powerful quantum computer.

To avoid garbled messages, mathematicians might translate them into geometric form.

Just five days after posting a retraction, László Babai announced that he had fixed the error in his landmark graph isomorphism algorithm.

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

The computer scientist Cynthia Dwork takes abstract concepts like privacy and fairness and adapts them into machine code for the algorithmic age.

Quanta Magazine invites readers to share about their early math and science learning experiences and to explore the interactive survey results.

The impasse in math and science instruction runs deeper than test scores or the latest educational theory. What can we learn from the best teachers on the front lines?

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

Computer scientists have come up with a bounded algorithm that can fairly divide a cake among any number of people.
