The 19th-century discovery of numbers called “quaternions” gave mathematicians a way to describe rotations in space, forever changing physics and math.
String theorists elide a paradox about black holes by extinguishing the walls of fire feared to surround them.
Evolution may have coopted an ancient metabolic mechanism to set social insects on the path toward one of the most puzzling behaviors found in nature.
Researchers explore a loophole that extracts useful energy from a fluid’s seemingly random motion. The secret? Sugar and asymmetry.
In the hunt for new fundamental particles, physicists have always had to make assumptions about how the particles will behave. New machine learning algorithms don’t.
Some species have the equivalent of many more than two sexes, but most do not. A new model suggests the reason depends on how often they mate.
What’s easy for a computer to do, and what’s almost impossible? Those questions form the core of computational complexity. We present a map of the landscape.
If and when physicists are able to pin down the metal content of the sun, that number could upend much of what we thought we knew about the evolution and life span of stars.
Astronomers suspect that there’s a large planet hiding out in the distant fringes of the solar system. At a recent workshop, they brainstormed ways to coax it into view.
