WXMI — In our science experiment today, we look at a disappearing coin trick, which really is no trick at all. It illustrates density and refraction. Some things are more dense (or heavier) than other ...

Scientists have ample evidence to prove the Earth is a sphere. But some social media users claim to have devised an experiment showing the earth is flat. The post shows a green laser beam projected ...

When it comes to light, certain types of fabricated materials behave in a radically different manner from ordinary materials like water and glass: they have negative refractive indices, so that light ...

THE experiments of Hill and Swallow 1 in August 1949 showed that the method of seismic refraction shooting at sea, which had been developed at Cambridge, was suitable for deep ocean work. Effort was ...

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 ...

Physicists are involved in an unusually heated debate over the reality of a new kind of refraction and about the possibility of making perfect lenses. Edwin Cartlidge reports. If you think science is ...
