The thorny thought experiment has been turned into a real experiment — one that physicists use to probe the physics of information.
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.
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.
Researchers are tracking the different strains of SARS-CoV-2 and studying how they spread through our population and our bodies.
Renormalization has become perhaps the single most important advance in theoretical physics in 50 years.
