Physics is supposed to be predictable. Drop a ball, and gravity pulls it down. Heat water, and it boils. Light travels in straight lines. Yet throughout history, scientists have encountered ...

Scientists at Nanyang Technological University in Singapore have discovered a surprisingly simple way to create exotic light ...

In day-to-day life, light seems intangible. We walk through it and create and extinguish it with the flip of a switch. But, like matter, light actually carries a little punch—it has momentum. Light ...

Researchers from Skoltech and the Shanghai Institute of Optics and Fine Mechanics have developed an approach that helps optimize the parameters of a laser-plasma source of attosecond pulses—ultrashort ...

The most beautiful experiment in physics, according to a poll of Physics World readers, is the interference of single electrons in a Young’s double slit. Robert P Crease reports Simply beautiful – the ...

(via Sabine Hossenfelder) The double-slit experiment is a famous quantum physics experiment that shows that light exhibits behavior of both a particle and a wave. In a new paper, researchers claim ...

Explore how laboratory experiments reveal the relationship between light wavelengths and the Faraday effect, uncovering ...

If photons possess more quantum states than expected, it would overhaul our understanding of all particle physics – and now physicists have identified a way to test this radical idea in an experiment.
