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 ...

In 1845, physicist Michael Faraday provided the first direct evidence that electromagnetism and light are related. Now, it turns out that this connection is even stronger than Faraday imagined. In his ...

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 ...

Chapter 1: What is light? There was a mystery in that assuming either light is a wave or a particle would result in contradictory phenomena, but today quantum electrodynamics is recognized as the most ...

Scientists have made discoveries about light particles known as photons that could aid the quest for fusion energy. Both literally and figuratively, light pervades the world. It banishes darkness, ...

University of Illinois Physics Professor Paul Kwiat and members of his research group have developed a new tool for precision measurement at the nanometer scale in scenarios where background noise and ...
