The carbon filament used in Edison’s 1897 light bulb experiments generated the precise amount of heat needed to produce ...

Quantum physics is the realm of the strange. And one of the strangest discoveries in the field is also one of the most fundamental: Particles fired at barriers with two slits in them can act like ...

Physics experiments have changed the world irrevocably, altering our reality and enabling us to take gigantic leaps in technology. From ancient times to now, here's a look at some of the greatest ...

In a mind-warping milestone experiment, scientists have been able to manipulate small numbers of individual photons of light, opening doors for the development of quantum technologies. This research, ...

A team of scientists has replicated one of Thomas Edison's early experiments from his quest to make the lightbulb, but with the aim of making graphene, rather than light. They succeeded, and they ...

Add Yahoo as a preferred source to see more of our stories on Google. optic fibres with different colours of light A paradox at the heart of quantum physics has been tested in an extraordinary fashion ...

Adam Sherwinski teaches ciLiving host, Jaclyn Friedlander about light refraction. Watch how light bends when it passes ...

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” in time. The new experiment is a twist on a 220-year-old demonstration, in which light shines through two slits in a ...

A new experiment has demonstrated something that sounds physically impossible – light itself casting a shadow. It turns out that if you manipulate a laser just right, then hit it side-on with another ...
