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

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 ...

Does light behave more like a particle, or like a wave? Today we know the surprising answer. Here's why it took so long to get there. When you purchase through links on our site, we may earn an ...

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 ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. This article is more than 4 years old. Light is well known to exhibit ...

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 ...

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 ...

Humans have problems with quantum mechanics. We have excellent intuition about the motion of a tennis ball tossed in the air, but what about an electron trapped in a box? The tendency is to use the ...

Quantum mechanics boasts all sorts of delightfully odd features. There's the fact that two separated particles can interact instantaneously, a phenomenon called quantum entanglement. (Einstein ...

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