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 ...

A groundbreaking new method developed at the University of Osaka calculates the entropy of liquids using a non-empirical approach, requiring only the atomic species as input. The paper is published in ...

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 ...
