A basic principle of quantum mechanics has been reaffirmed. Stop the presses. (Or start the tweeting.) It’s no surprise, really, for quantum physics to withstand another assault. It would have been ...

Now that LIGO has detected their first gravitational wave signal, the part of Einstein's theory that predicts that the fabric of space itself should have ripples and waves in it has been confirmed.

In physics and chemistry, wave-particle duality holds that light and matter exhibit properties of both waves and of particles. A central concept of quantum mechanics, duality addresses the inadequacy ...

Quantum objects are notoriously shifty. Take the photon, for example. The quantum of light can act as a particle one moment, following a well-defined path like a tiny projectile, and a wave the next, ...

Photon duality remains a paradox because the photon is regarded as a simple, unitary object in space. Equally bad, massless radiation is interpreted via concepts drawn from mass-based physics. The ...

Here's a nice surprise: quantum physics is less complicated than we thought. An international team of researchers has demonstrated that two peculiar features of the quantum world previously considered ...

Wave-particle duality is a fundamental fact of the Universe. But we don't see many objects moving around as waves. This is why it hurts when a golf ball hits you on the head: you and the golf ball are ...

The subtlest experiment in quantum mechanics is also one of the simplest: send a stream of particles through two openings in a barrier, and you'll produce an interference pattern because the particles ...

Since its development 100 years ago, quantum mechanics has revolutionized our understanding of nature, revealing a bizarre world in which an object can act like both waves and particles, and behave ...

The concept of wave-particle duality ascribes two seemingly contradictory traits to a single object. Wave–particle duality is a concept in particle physics that ascribes two seemingly contradictory ...
