Dark matter is an elusive type of matter that does not emit, reflect or absorb light, yet is estimated to account for most of ...

Researchers have used a 350-year-old theorem to better understand the strange nature of light. The team took a theorem used for describing pendulums and substituted the brightness of light in for what ...

Scientists have recently discovered an interaction between an electromagnetic wave and its own magnetic component as it ...

Physicists use a 350-year-old theorem that explains the workings of pendulums and planets to reveal new properties of light waves. Since the 17th century, when Isaac Newton and Christiaan Huygens ...

Scientists have used a new method to determine the characteristics of optical, i.e. light-based, quantum states. For the first time, they are using certain photon detectors -- devices that can detect ...

Light corn syrup is used to rotate the plane of polarized light on the stage of an overhead projector. A polarizing filter allows only those photons with electric fields oscillating in a single plane ...

Forbes contributors publish independent expert analyses and insights. I write about physics, science, academia, and pop culture. There's an episode of Star Trek: The Next Generation in which John de ...
