Scientists have made the first experimental observation of matter wave diffraction in a short-lived electron-positron atom.

Schematic of the MIT experiment: Two single atoms floating in a vacuum chamber are illuminated by a laser beam and act as the two slits. The interference of the scattered light is recorded with a ...

The quantum physics of massive particles has intrigued physicists for more than 80 years, since it predicts that even complex particles can exhibit wave-like behaviour – in conflict with our everyday ...

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 ...

Physicists in Leiden have recreated Thomas Young’s iconic double-slit experiment using gigahertz sound waves on gallium arsenide, revealing both parallels and differences with light. The study found ...

Physics is simple. In fact, it never ceases to astonish me how, with a few simple ideas from physics in your suitcase, you can travel from your own backyard to the most exotic realms of the universe, ...

Wave or particle? Science continues to unravel one of humanity's greatest mysteries in this universe in rather useful ways.

One of the great counterintuitive puzzles of quantum mechanics is wave-particle duality. This is the phenomenon in which objects behave both like particles and like waves. Numerous experiments have ...

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 ...
