How Maxwell’s Demon Continues to Startle Scientists
The thorny thought experiment has been turned into a real experiment — one that physicists use to probe the physics of information.
Mathematicians Find a New Class of Digitally Delicate Primes
Despite finding no specific examples, researchers have proved the existence of a pervasive kind of prime number so delicate that changing any of its infinite digits renders it composite.
Matrix Multiplication Inches Closer to Mythic Goal
A recent paper set the fastest record for multiplying two matrices. But it also marks the end of the line for a method researchers have relied on for decades to make improvements.
How to Understand COVID-19 Variants and Their Effects on Vaccines
Researchers are tracking the different strains of SARS-CoV-2 and studying how they spread through our population and our bodies.
How Mathematical ‘Hocus-Pocus’ Saved Particle Physics
Renormalization has become perhaps the single most important advance in theoretical physics in 50 years.
