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

Scientists test Einstein’s quantum challenge with one atom, directly measuring when photon paths erase interference stripes.

[Stoppi] has taken on a fascinating project involving the interference of thin layers, a phenomenon often observed in everyday life but rarely explored in such depth. This project delves into the ...

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

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 ...

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

The film "Introduction to Holography" explains the principles of holography, focusing on how it differs from traditional photography by creating three-dimensional images. It discusses the role of wave ...

When wave pass through each other, they interfere, producing neat effects. Artist Gary Drostle harnesses the interference patterns as light passes through rippling water to create fish pond mosaics.

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 ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. Back in February of 2016, LIGO made an announcement that changed our ...
