A beam of light, by the rules physicists have relied on for more than a century, can only be squeezed so small. Push it into a tighter space and it simply leaks out, a constraint known as the ...
When Gabriel Lippmann collected the 1908 Nobel Prize in Physics, he did so for an invention he himself admitted was of limited practical use. His method of colour photography, based on optical ...
Scientists awarded for light pulses that capture electron moves Findings could advance electronics and medical diagnostics Laureates share $1 million prize Second Nobel prize of this year's line-up ...
Researchers have cracked a fundamental optical challenge: how to control both angle and wavelength of light independently—a problem that’s limited imaging and display technologies for years. By ...
A quantum experiment that sees a particle of light travel both forwards and backwards in time, at the same moment, is yet another example of the weirdness of the quantum realm. Although this ...
