When two or more light waves interact with one another, they result in the formation of different interference patterns. British physicist Thomas Young first demonstrated and explained these patterns ...

Quantum physics is the realm of the strange. And one of the strangest discoveries in the field is also one of the most fundamental: Particles fired at barriers with two slits in them can act like ...

Physicists have trapped light inside a miniature ring so that it needs two round trips to get back to its initial configuration, like an ant that must make two circuits around the surface of a Möbius ...
