Though a cornerstone of thermodynamics, entropy remains one of the most vexing concepts to teach budding physicists in the classroom. Physics teachers designed a hand-held model to demonstrate the ...

Entropy production lies at the heart of non-equilibrium thermodynamics, a field that examines systems away from equilibrium where continuous energy flows and irreversible processes dominate.

If you define the concept of entropy in a way that is compatible with the basic ideas of quantum physics, then there is no longer any contradiction between quantum physics and thermodynamics.

Nonequilibrium Thermodynamics: The study of systems that are not in thermodynamic equilibrium, focusing on the flows of energy and matter and the production of entropy.

The dream of time travel has fueled stories, films, and scientific debates for generations. The idea that you could step into ...

A. Kleidon, A basic introduction to the thermodynamics of the Earth system far from equilibrium and maximum entropy production, Philosophical Transactions: Biological Sciences, Vol. 365, No. 1545, ...

The perceived arrow of time, however, seems largely independent of anything entropy or thermodynamics may do. What, if anything, happens when we bring the expanding Universe into the equation?

An international team of physicists kept solid gold intact while superheating it to 19,000 Kelvin, about 33,740 degrees Fahrenheit ...
