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 ...

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.

Ever since Democritus – a Greek philosopher who lived between the 5th and 4th century's BCE – argued that all of existence was made up of tiny indivisible atoms, scientists have been speculating as to ...

MIT tests light's wave-particle duality with atoms, resolving a century-old quantum debate between Einstein and Bohr. (CREDIT: Science Photo Library) In a striking display of quantum physics, a team ...

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 ...

Light is a paradox. It is associated with wisdom and knowledge, with the divine. The Enlightenment proposed the light of reason as the guiding path toward truth. We evolved to identify visual patterns ...

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 ...

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 ...

Wave and particle properties of light are discussed. Wave and particle properties of light are discussed and students come to a conclusion about the nature of light. Methods for production of light ...
