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 ...

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 ...

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 ...

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 ...

Quantum entanglement is often described as a mysterious link between particles, but new research shows it may be even richer ...

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 ...

Light is well known to exhibit both wave-like and particle-like properties, as imaged here in this 2015 photograph. What's less well appreciated is that matter particles also exhibit those wave-like ...
