Our notion of reality is built on everyday experiences. But wave-particle duality is so strange that we are forced to re-examine our common conceptions. Wave-particle duality refers to the ...

The wave-particle duality is one of those essential pillars. Physics courses devote weeks to just introducing it – but there are still important aspects that can be covered in a short article.

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.

Basically, this demonstrates that wave-particle duality is like a chameleon in the quantum mechanic culture. The creature changes form but is still the same thing.

Is it a wave, or is it a particle? This seems like a very simple question — except when it isn't. And it isn't in one of the most important aspects of our universe: the subatomic world.

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 ...

Electrons are elementary particles -- indivisible, unbreakable. But new research suggests the electron's quantum state -- the electron wave function -- can be separated into many parts. That has ...
