Wave-particle duality is a fundamental fact of the Universe. But we don’t see many objects moving around as waves. This is why it hurts when a golf ball hits you on the head: you and the golf ball are ...

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 ...

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. While ...

For the first time, physicists have watched a beam of positronium, a short‑lived atom made of an electron and its antimatter twin, behave like a rippling quantum wave instead of a stream of tiny ...

Quantum physics tells us about the properties and behaviors of atomic and subatomic particles. But scientists have long held the belief that the rules that govern the microscopic world should also be ...

Antimatter isn't just made of antiparticles, it's also made of waves. Now we know that this holds true even at the level of a single antimatter particle. Physicists have known for a long time that ...

The inherent contradiction in the way energy behaves. At the turn of the 20th century, it was believed that light was electromagnetic waves and electrons were particles. By the 1930s, it was ...

Researchers from Linköping University together with colleagues from Poland and Chile have confirmed a theory that proposes a connection between the complementarity principle and entropic uncertainty.
