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 ...

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 ...

The Irish mathematician and physicist William Rowan Hamilton, who was born 220 years ago last month, is famous for carving ...

The double-slit experiment is one of the most famous experiments in physics and definitely one of the weirdest. It demonstrates that matter and energy (such as light) can exhibit both wave and ...

The heart of quantum mechanics is the wave-particle duality: matter and light possess both wave-like and particle-like attributes. Typically, the wave-like properties are inferred indirectly from the ...

By using something called a quantum grid, scientists have found a clever way to simultaneously measure momentum and position ...

We explore Objective Collapse Theories in a down to earth objective way. Objective Collapse Theories offer a explanation of quantum mechanics that is at once brand new and based in classical mechanics ...

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.

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. Scientists have long known that light can behave as both a particle ...

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 ...

From the most distant stars in the sky to the screen in front of your face, light is everywhere. But the exact nature of ...
