How AI Discovered a Faster Matrix Multiplication Algorithm

DeepMind researchers trained an AI system called AlphaTensor to find new, faster algorithms for matrix multiplication. AlphaTensor quickly rediscovered — and surpassed, for some cases — the reigning algorithm discovered by German mathematician Volker Strassen in 1969.

Can a New Law of Physics Explain a Black Hole Paradox?

A group of physicists recently used circuit complexity, a concept from computer science, to describe the quantum evolution of physical systems. Some computer scientists who initially balked at the idea have since become its closest allies.

Could One Physics Theory Unlock the Mysteries of the Brain?

Some neuroscientists hypothesize that our brains work optimally at a "critical point" between subcritical and supercritical extremes. If so, brain diseases like epilepsy could be associated with a divergence from the critical point.

When Computers Write Proofs, What's the Point of Mathematicians?

What is a mathematical proof? What we tend to think of as an eternal, immutable truth, is perhaps better understood as a social construct, number theorist Andrew Granville explains.

P vs. NP: The Greatest Unsolved Problem in Computer Science

How hard is it to prove that a problem is hard? This question is at the heart of meta-complexity, an area of theoretical computer science with implications that go far beyond any specific technology.
