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 ...

In order to build the computers and devices of tomorrow, we have to understand how they use energy today. That's harder than it sounds. Memory storage, information processing, and energy use in these ...

Entropy, the amount of molecular disorder, is produced in several systems but cannot be measured directly. An equation developed by researchers at Chalmers University of Technology and Heinrich Heine ...
