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

Researchers have demonstrated that a nanoparticle of 7,000 sodium atoms can act as a wave, creating a record-setting ...

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 ...

For more than a century, scientists have known that waves can behave in ways that seem to defy common sense, from freak walls ...

A sensitive matter-wave interferometer measuring moiré fringes offers force sensitivity comparable to quantum interference ...

A groundbreaking experiment demonstrates yet again that light exists both as a wave and a particle in the quantum world—but we can’t see both at the same time. Reading time 3 minutes Albert Einstein ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. When we divide up matter into the smallest possible chunks that it's ...

When I began my master’s program in cognitive science, an electrical engineering professor told us—rather arrogantly—that the soul is nothing but neurons firing. “You’re deluded if you think otherwise ...

Light is well known to exhibit both wave-like and particle-like properties, as imaged here in this 2015 photograph. What's less well appreciated is that matter particles also exhibit those wave-like ...
