Researchers manipulated water waves to move ping pong balls with a level of precision that seems straight out of a sci-fi movie.

The stars as seen from Earth would have looked dimmer 14 million years ago, as the solar system was in the middle of passing ...

By adjusting the light waves, the particles stuck in them could ... or spin about and move precisely along a circular or spiral path in the patterns, deviating at most 2–4 mm from the path.

Remove the block. Join the crosses to show the paths of the light rays towards and away from the block. Join the incident ray to the emergent ray to show the path of the light through the block.

Wave-particle duality and entanglement are cornerstone concepts in quantum physics, yet their exact relationship has long ...
