Scientists have demonstrated that negative refraction can be achieved using atomic arrays -- without the need for artificially manufactured metamaterials. Scientists have long sought to control light ...

Since ancient times, people have experimented with light, cherishing shiny metals like gold and cutting gemstones to brighten their sparkles. Today we are far more advanced in how we work with this ...

Scientists have created a new class of laser beam that appears to violate long-held laws of light physics. These new beams, which the team calls “spacetime wave packets,” follow different rules of ...

Explores the principles of light, reflection, and magnification through hands-on experiments. Children observe how a magnifying glass focuses sunlight to create heat, examine the effects of light on ...

Step into the hidden science lab in your kitchen with five easy experiments that explain refraction, surface tension, ...

THE discovery by Prof. Röntgen of the rays which bear his name has aroused an interest perhaps unparalleled in the history of physical science. Reports of experiments on these rays come daily from ...
