In physics, the conundrum known as the 'few-body problem,' how three or more interacting particles behave, has bedeviled scientists for centuries. Equations that describe the physics of few-body ...

Physicists have transformed a decades-old technique for simplifying quantum equations into a reusable, user-friendly "conversion table" that works on a laptop and returns results within hours. When ...

A college student in Switzerland says he’s solved a 100-year-old physics problem. The question is about an air bubble trapped in a very narrow tube of liquid, where the bubble appears to be “stuck,” ...
