This story was originally written for and published by Drexel News. Researchers in the College of Engineering have developed a thin film device, fabricated by spray coating, that can block ...

Artificial intelligence is colliding with a hard physical limit: the energy and heat of today’s silicon-based chips. As ...

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 ...

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 ...

Perhaps one of the most famous experiments in physics has been giving us the wrong message all these years. For nearly two centuries, the double-slit experiment has been providing a direct visual ...

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 ...

An international team of researchers has succeeded in steering light waves deep into “forbidden” regions of photonic crystals by manipulating the shape of the waves. The technique, which was developed ...

A new concept for energy transfer between gravitational waves and light. When massive cosmic objects such as black holes merge or neutron stars crash into one another, they can produce gravitational ...

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 ...

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 ...
