At the smallest scales of nature, the rules of the world shift in ways that can feel unsettling and beautiful at the same ...

Physicists have finally watched positronium, a short‑lived atom made of an electron and its antimatter twin, behave like a rippling quantum wave instead of a tiny billiard ball. In a set of ...

The classic signature of wave-particle duality in quantum particles is the wave-like interference pattern that is produced when a beam of particles passes through a ‘double-slit’. Researchers have ...

“For two years, I was looking at flat lines,” physicist Sebastian Pedalino recalled of a stubborn detector that refused to show anything but noise. The evening when the signal at last expanded out ...

Quantum physics tells us about the properties and behaviors of atomic and subatomic particles. But scientists have long held the belief that the rules that govern the microscopic world should also be ...

Researchers report on the unexpected observation of thermal waves in germanium for the first time. (Courtesy: ICMAB/UAB) Researchers in Spain and Italy have observed “second sound” in a ...

Light's behavior seems counterintuitive. That is, until you figure out light is a wave. The way light behaves can seem very counterintuitive, and many physicists would agree with that, but once you ...
