Scientists have made the first experimental observation of matter wave diffraction in a short-lived electron-positron atom. A ...

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 ...

Quantum mechanics theory predicts that, in addition to exhibiting particle-like behavior, particles of all sizes can also have wave-like properties. These properties can be represented using the wave ...

Two of the forefathers of quantum theory, Albert Einstein and Niels Bohr, had a famous argument over whether light is a wave ...

Ship waves, the complex patterns generated as vessels displace water, remain a subject of significant scientific and engineering interest. Traditionally described by Kelvin’s theory of ship wakes, ...

New interference radar functions improve the distance resolution between objects using radar waves. The results may have important ramifications in military, construction, archaeology, mineralogy and ...

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 ...

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 ...
