Have you ever wondered what the invisible world of radio waves might look like if you could actually see it? Rootkid explains how his project, the Spectrum Slit, transforms the unseen chaos of ...

Imperial physicists have recreated the famous double-slit experiment, which showed light behaving as particles and a wave, in time rather than space. The experiment relies on materials that can change ...

In a first, scientists have shown that they can send light through "slits" in time. The new experiment is a twist on a 220-year-old demonstration, in which light shines through two slits in a screen ...

The shape of liquid interfaces can be precisely controlled using electrowetting, an actuation mechanism which has been widely used for tunable optofluidic micro-optical components such as lenses or ...
