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 ...

A tool for estimating the local entropy production rate of a system enables the visualization and quantification of the out-of-equilibrium regions of an active-matter system. Figure 1: Researchers ...

Geared toward those interested in the engineering and physics of air-conditioning and refrigeration devices (chillers), this book focuses on mechanical (electrically-driven) chillers with substantial ...

A paper published July 16, 2026 in Physical Review D offers a mathematically precise resolution to one of physics' oldest irritants: the universe has been growing more disordered for 13.8 billion ...
