Researchers in Drexel University's College of Engineering have developed a thin film device, fabricated by spray coating, that can block electromagnetic radiation with the flip of a switch. The ...

Waves can reinforce each other, and they can also cancel each other out.Last time, I talked about how various "waves" are constantly passing back and forth around us. I spoke about how, using ...

Interference in plane-wave combinations of water waves is predicted to give rise to structures that are usually found in optical, elastic, and quantum systems. Figure 1: Water surface waves can form ...

A theory inspired by whale tracking suggests that interference could make the peak of a light-wave packet appear to travel faster than light—without transmitting information superluminally. Whales are ...

Thomas Young, born 250 years ago this week, was a polymath who made seminal contributions in fields from physics to Egyptology. But perhaps his most enduring legacy is proving Isaac Newton wrong about ...

One of the great counterintuitive puzzles of quantum mechanics is wave-particle duality. This is the phenomenon in which objects behave both like particles and like waves. Numerous experiments have ...
