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 ...

An experiment measuring a single atom's recoil confirmed that observing a particle destroys interference, settling the ...

Metal clusters made of thousands of atoms showed quantum interference, offering new insight into how large objects follow quantum rules.

Thomas Young, born 250 years ago this week, was a polymath who made seminal contributions in fields from physics to Egyptology. But perhaps his most enduring legacy is proving Isaac Newton wrong about ...
