The Irish mathematician and physicist William Rowan Hamilton, who was born 220 years ago last month, is famous for carving some mathematical graffiti into Dublin's Broome Bridge in 1843. Subscribe to ...

Classical physics theories suggest that when two or more electromagnetic waves interfere destructively (i.e., with their electric fields canceling each other out), they cannot interact with matter. In ...

Long before quantum mechanics existed, a scientist developed a powerful way of describing motion by drawing an analogy between particles and light.

It's an age-old question and one that any meteorologist hears quite often. Why is the sky blue? It has to do with light waves and how they travel through our atmosphere. The light from our sun travels ...

Physicists have finally watched positronium, a short‑lived atom made of an electron and its antimatter twin, behave like a rippling quantum wave instead of a tiny billiard ball. In a set of ...

Could invisibility cloaks become a reality? New research brings this science fiction concept a step closer, with a breakthrough software package that simulates how waves interact with complex ...

Did you know that the world around us is filled with different types of light waves ? From the warm glow of the sun to audible radio waves and invisible gamma rays, electromagnetic waves (action ...

This image is a simulation of a kind of acoustic wave called a Rayleigh-Bloch wave. The stripes of light and dark areas represent the “peaks" and “troughs" of the waves and are shaped by their ...
