Just five days after posting a retraction, László Babai announced that he had fixed the error in his landmark graph isomorphism algorithm.
Gaining an intuition about half-life requires some unintuitive thinking.
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.
By folding fractals into 3-D objects, a mathematical duo hopes to gain new insight into simple equations.
A simple and elegant way to stack identical flat objects so that they project over an edge as far as possible.
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.
What formula describes the farthest you can stack flat blocks over the edge of a table to form a seemingly gravity-defying half-bridge to nowhere?
An unexpected connection has emerged between the results of physics experiments and an important, seemingly unrelated set of numbers in pure mathematics.
