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 ...

Chemists of the University of Bonn developed a computational tool for the analysis of conformational entropies of flexible molecules. Their method enables the thermodynamic investigation of ...

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.

For Boris Belousov, vindication came too late. When the Soviet biochemist was awarded his country’s prestigious Lenin prize in 1980, he had been dead for 10 years. At least he lived long enough to see ...

In a study published in Physical Review Letters, physicists have demonstrated that black holes satisfy the third law of thermodynamics, which states that entropy remains positive and vanishes at ...
