Famous Fluid Equations Spring a Leak
Researchers have spent centuries looking for a scenario in which the Euler fluid equations fail. Now a mathematician has finally found one.
Mathematician Proves Huge Result on ‘Dangerous’ Problem
Mathematicians regard the Collatz conjecture as a quagmire and warn each other to stay away. But now Terence Tao has made more progress than anyone in decades.
Black Hole Singularities Are as Inescapable as Expected
For the first time, physicists have calculated exactly what kind of singularity lies at the center of a realistic black hole.
Karen Uhlenbeck, Uniter of Geometry and Analysis, Wins Abel Prize
A founder of modern geometric analysis who produced “some of the most dramatic advances in mathematics in the last 40 years,” Uhlenbeck is the first woman to be awarded this top honor.
The Trouble With Turbulence
Turbulence is everywhere, yet it is one of the most difficult concepts for physicists to understand.
A Traveler Who Finds Stability in the Natural World
The mathematician Alessio Figalli is rarely in one place for very long. But his work has established the stability of everything from crystals to weather fronts by using concepts derived from Napoleonic fortifications.
Mathematicians Tame Turbulence in Flattened Fluids
By squeezing fluids into flat sheets, researchers can get a handle on the strange ways that turbulence feeds energy into a system instead of eating it away.
Mathematicians Disprove Conjecture Made to Save Black Holes
Mathematicians have disproved the strong cosmic censorship conjecture. Their work answers one of the most important questions in the study of general relativity and changes the way we think about space-time.
How Einstein Lost His Bearings, and With Them, General Relativity
By 1913, Albert Einstein had nearly completed general relativity. But a simple mistake set him on a tortured, two-year reconsideration of his theory. Today, mathematicians still grapple with the issues he confronted.
