The French mathematician was cited “for his pivotal role in the development of the mathematical theory of wavelets.”

Top women in mathematics and physics discuss how they got to where they are—and why there aren’t more of them.

19th-century mathematicians thought the “roots of unity” were the key to solving Fermat’s Last Theorem. Then they discovered a fatal flaw.

The circadian clock is in nearly every cell, and researchers have untangled many of its secrets. But sleep has been harder to pin down.

The simple Möbius strip illustrates a deep mathematical challenge that has long tormented the field of symplectic geometry.

Without viruses, we might never have evolved.

Life might have originated in droplets that behave surprisingly like living cells.

László Babai has fixed the flaw in his retracted claim.

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.

A mission to collect samples from the far side of the moon could answer questions about a barrage of asteroids nearly 4 billion years ago.

The effort to unify quantum mechanics and general relativity means reconciling totally different notions of time.

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.

So-called “analogue experiments” are becoming increasingly common in physics, but do they teach or mislead?
