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 ...

Two of the forefathers of quantum theory, Albert Einstein and Niels Bohr, had a famous argument over whether light is a wave ...

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 ...

Stephen has degrees in science (Physics major) and arts (English Literature and the History and Philosophy of Science), as well as a Graduate Diploma in Science Communication. Stephen has degrees in ...

For the first time, researchers measured singularities in combined light and sound waves moving faster than the speed of ...

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 ...

Although Danish physicist Niels Bohr's atomic model was tremendously successful, and experiments by Moseley and Franck-Hertz strongly supported it, the bold hypotheses of the Bohr model were just that ...

A new study, published in Physical Review Letters, reports that scientists have successfully imaged the formation of ...

A dark point inside a wave of light sounds like a contradiction. It is also something researchers say they have now viewed in ...

Everything on the electromagnetic spectrum has some properties of both waves and particles, but it’s difficult to imagine a radio wave, for example, behaving like a particle. The main evidence for a ...
