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, ...

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 ...

Recently, it was reported that an experiment was done to prove that light(or photons) can act as both a wave and a particle. One central theme to quantum mechanics is wave-particle duality. This is ...

Complementarity A new twist on the double-slit experiment. (Courtesy: Shutterstock/Andrey VP) One of the most counterintuitive concepts in physics – the idea that quantum objects are complementary, ...

What is light made of: waves or particles? This basic question has fascinated physicists since the early days of science. Quantum mechanics predicts that photons, particles of light, are both ...

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 ...

According to quantum mechanics, the physics theory that describes the zoo of subatomic particles, all matter can be described as both particles and waves. But is it real? When you purchase through ...

Is light made of waves, or particles? This fundamental question has dogged scientists for decades, because light seems to be both. However, until now, experiments have revealed light to act either ...

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 ...

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 ...

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 ...

Classically, light can be thought of in two ways: either as a particle or a wave. But what is it really? Well, the ‘observer effect’ makes that question kind of difficult to answer. So before we get ...
