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 ...

Imagine standing by a lake and throwing a stone into the water. Waves spread out in circular patterns and can reflect at obstacles and boundaries. Researchers at the University of Regensburg, in ...

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 ...

The gravitational wave transmits an energy packet to the light wave. It should be feasible to observe both phenomena, namely, the stimulated emission and absorption of gravitons, although this would ...

Introduction Have you ever noticed seagulls bobbing up and down on the ocean? You might have also seen surfers catch a wave that takes them to shore. Maybe you have floated on a lake, going up and ...

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 ...

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 ...
