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 ...

In quantum mechanics, particles do not have a distinct position in space. Instead, they exist as a wave function, a probability distribution that includes all the possible locations where a particle ...

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 ...

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 ...

It’s a fundamental property of the universe, and one that continues to blow people’s minds: photons behave as both particles and waves, matter and energy. Photons aren’t alone in this—every elemental ...

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 ...

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.

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 ...

It’s in your physics textbook, go look. It says that you can either model light as an electromagnetic wave OR you can model light a stream of photons. You can’t use both models at the same time. It’s ...
