At Long Last, Mathematical Proof That Black Holes Are Stable

Quanta Magazine: In 1963, the mathematician Roy Kerr found a solution to Einstein’s equations that precisely described the space-time outside what we now call a rotating black hole. (The term wouldn’t be coined for a few more years.) In the nearly…

How Florence Nightingale Changed Data Visualization Forever

Scientific American: In the summer of 1856 Florence Nightingale sailed home from war furious. As the nursing administrator of a sprawling British Army hospital network, she had witnessed thousands of sick soldiers endure agony in filthy wards. An entire fighting force…

Weyl loops link up

Physics World: For the first time, a team of physicists have observed quantum mechanical structures known as Weyl loops linking up to form chains. These structures, which are formed from quantum states of electrons in crystalline cobalt manganese gallium (Co2MnGa), have a novel topology and must be described using knot…

In Times of Scarcity, War and Peace, a Ukrainian Finds the Magic in Math

Quanta Magazine: In late February, just weeks after Maryna Viazovska learned she had won a Fields Medal — the highest honor for a mathematician — Russian tanks and war planes…
