AI Reveals New Possibilities in Matrix Multiplication
Inspired by the results of a game-playing neural network, mathematicians have been making unexpected advances on an age-old math problem.
Chaos Researchers Can Now Predict Perilous Points of No Return
A custom-built machine learning algorithm can predict when a complex system is about to switch to a wildly different mode of behavior.
Wheel Made of ‘Odd Matter’ Spontaneously Rolls Uphill
Physicists have solved a key problem of robotic locomotion by revising the usual rules of interaction between simple component parts.
Physicists Pin Down How Quantum Uncertainty Sharpens Measurements
Throwing out data seems to make measurements of distances and angles more precise. The reason why has been traced to Heisenberg’s uncertainty principle.
Four Years On, New Experiment Sees No Sign of ‘Cosmic Dawn’
When astronomers tried to confirm a signal from the birth of the first stars after the Big Bang, they saw nothing.
How Bell’s Theorem Proved ‘Spooky Action at a Distance’ Is Real
The root of today’s quantum revolution was John Stewart Bell’s 1964 theorem showing that quantum mechanics really permits instantaneous connections between far-apart locations.
