A new experiment confirms that angular momentum conservation holds even when a single photon is split into two.

When you shine a flashlight into a glass of water, the beam bends. That simple observation, familiar since ancient times, ...

For centuries, scientific progress has depended on more precise tools for measuring the world around us. Galileo’s telescope ...

Since the early 20th century physicists have known that light carries momentum, but the way that this momentum changes as light passes through different media is much less clear. Two rival theories of ...

The interplay between angular momentum, electron spin and magnetism at the nanoscale could have applications in spintronics, transducers and actuators, as well as fundamental research. In 1915, Albert ...
