Gravitational waves are usually hunted by measuring distance—how space itself stretches and shrinks ever ...

Physics fans are a lot like surfers. Both think waves are really fun. For surfers, it’s all about having a good time. For physicists, it’s about understanding some of nature’s most important physical ...

The control of matter motion at liquid–gas interfaces opens an opportunity to create two-dimensional materials with remotely tunable properties. In analogy with optical lattices used in ultra-cold ...

In 2005, a student working in the fluid physicist Yves Couder’s laboratory in Paris discovered by chance that tiny oil droplets bounced when plopped onto the surface of a vibrating oil bath. Moreover, ...

Wave-particle duality is a fundamental fact of the Universe. But we don’t see many objects moving around as waves. This is why it hurts when a golf ball hits you on the head: you and the golf ball are ...

Gravitational waves are the last great prediction of general relativity to be directly observed. According to Einstein's theory of gravity, a mass in motion creates ripples in space and time. Ripples ...

Electron microscope image of the superfluid wave tank used in the experiments (blue) coupled to an optical fibre which brings laser light in and out of the device. The zoom-in shows the photonic ...

Researchers studying wave breaking have found that axisymmetric 'spike waves' can far exceed limits that were previously thought to dictate the maximum height of ocean waves. Researchers studying wave ...
