Gravity is supposed to be the most familiar force in nature, yet at the deepest level it remains the least understood. A bold new line of research now argues that gravity is not fundamental at all, ...

Entropy also increases in initially ordered quantum systems until it reaches a final state of disorder. Entropy and the direction of time Equating 'entropy' with 'disorder' is not entirely correct.

In a study published in Nature, researchers have used ultrafast laser heating and high-resolution inelastic X-ray scattering to explore the extreme limits of gold's structural stability. The 'entropy ...

Entropy is one of the most useful concepts in science but also one of the most confusing. This article serves as a brief introduction to the various types of entropy that can be used to quantify the ...
