(Hans Strand/Corbis Documentary/Getty Images) Some truths about the Universe seem absolute. Entropy flows one way. Gravity sucks. And nothing can outrun the speed of light. But a quirk of how sound ...

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 ...

A collaboration of Professor Szameit's research group at the University of Rostock with researchers from the Albert-Ludwigs-Universität Freiburg has succeeded in stabilizing the interference of two ...

Light is well known to exhibit both wave-like and particle-like properties, as imaged here in this 2015 photograph. What's less well appreciated is that matter particles also exhibit those wave-like ...

Fig. 1 THz wave generation from MoS2 through quantum interference. (a) Schematic diagram of THz wave generation from MoS2 under two-color light excitation at normal incidence. (b) THz waveforms ...

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 ...

A sine wave represents a wave, whether it be a water wave traveling toward a beach or a sound wave created by a single musical note. The figure below shows the components of a simple sine wave. In a ...
