Researchers have found that a swirling water vortex can force opposing waves to form rotating lines of stillness across an entire tank. That result turns a famously hard-to-see quantum effect into ...

Lines of momentarily flat water extend outward and rotate, in the opposite direction to the flow of the vortex. The left video shows the pattern from the experiment, while the right video shows the ...

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 ...

Where there's water, there are waves. But what if you could bend water waves to your will to move floating objects? Scientists have now developed a technique to merge waves in a water tank to produce ...
