According to the second law of thermodynamics, the total entropy of a closed process can increase or stay the same, but never decrease. The second law guarantees, for example, that an egg can wobble ...

A new theoretical study offers a possible explanation for how the Universe can grow more complex without violating the second law of thermodynamics. Using a quantum gravity framework called Gravity ...

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 ...

How it works When laser light passes through a cavity filled with atoms, part of it can do useful work. In this example the work is charging a quantum battery (top). The rest of the light turns into ...

We all know that to have life on a world, you need three critical items: water, warmth, and food. Now add to that a factor called "entropy." It plays a role in determining if a given planet can ...

Entropy, the amount of molecular disorder, is produced in several systems but cannot be measured directly. A new equation sheds new light on how entropy is produced on a very short time scale in laser ...

Because of their exceptional capability to tailor the effective medium parameters, metamaterials have been widely used to control electromagnetic waves, which has led to the observation of many ...
