Photons are particles of light, or waves, or something like that, right? [Mithuna Yoganathan] explains this conundrum in more detail than you probably got in your high school physics class. While ...

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 ...

This is an artist's depiction of what a group of atoms looks like when they merge to a wave-like state. This occurs under ultra-cooling that drops atoms' temperature to near absolute zero, the coldest ...

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 source of a photon affects how much it will exhibit particle-like or wave-like behaviour. One of the most intriguing aspects of quantum physics is that quantum entities such as electrons and ...

Light is a paradox. It is associated with wisdom and knowledge, with the divine. The Enlightenment proposed the light of reason as the guiding path toward truth. We evolved to identify visual patterns ...

In a modern version of the famed double-slit experiment, physicists demonstrated that light cannot behave as both wave and particle simultaneously, overturning a key premise Einstein held. The ...
