The types of glass that we encounter in everyday life, such as window glass or smartphone screens, are disordered solids. This means that they consist of particles locked in place, like those in ...

Some solid materials can cool down or heat up when pressure is applied or released. This behavior enables cooling and heating ...

The ease of recovering information that was not properly redacted digitally suggests that at least some of the documents released by the Justice Department were hastily censored. By Santul Nerkar ...

Abstract: In this paper, we examine the Rényi entropy rate of stationary ergodic processes. For a special class of stationary ergodic processes, we prove that the Rényi entropy rate always exists and ...

While quantum entanglement mimicks the first law of thermodynamics in terms of entropy in a system, scientists wonder if the second law—especially the part about reversibility—could hold true. A new ...

Just over 200 years after French engineer and physicist Sadi Carnot formulated the second law of thermodynamics, an international team of researchers has unveiled an analogous law for the quantum ...

Where does time really come from? I am often asked this question after acquaintances or friends of friends learn that I am a physics reporter. There is not a set answer – but to better understand it, ...

Reversible architecture refers to a design and construction approach in which the structures and components of a building can be easily assembled, disassembled, modified, or reconfigured with minimal ...

Billy Joel revealed he was recently diagnosed with normal pressure hydrocephalus (NPH), a rare, but reversible type of dementia. The statement notes that performing worsened some of the 76-year-old ...
