In day-to-day life, light seems intangible. We walk through it and create and extinguish it with the flip of a switch. But, like matter, light actually carries a little punch—it has momentum. Light ...

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 ...

Processes in the X-ray interferometer: The path of a single photon (pink) passes through two slits simultaneously and spreads out behind them into a characteristic “interference pattern”. This pattern ...

For the first time, scientists have demonstrated that negative refraction can be achieved using atomic arrays—without the need for artificially manufactured metamaterials. Scientists have long sought ...

Physics is supposed to be predictable. Drop a ball, and gravity pulls it down. Heat water, and it boils. Light travels in straight lines. Yet throughout history, scientists have encountered ...

I test a series of light experiments to explore reflection, refraction, and optical illusions, demonstrating how light behaves in surprising and educational ways. 10 rescued after huge sinkhole opens ...
