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. In such ...

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 is surely one of the most intriguing and misunderstood concepts in all of physics. The entropy of the universe must always increase – so says the second law of thermodynamics. It’s a law that ...

As physicists extend the 19th-century laws of thermodynamics to the quantum realm, they’re rewriting the relationships among energy, entropy and information. In his 1824 book, Reflections on the ...

Entropy is behind one of the most fundamental laws of physics. Entropy is surely one of the most perplexing concepts in physics. It’s variously described as a measure of a system’s disorder - or as ...

Behind the veil: A black hole's event horizon contains an infinite number of microstates, but expressing these microstates in terms of a finite set of representative quantum superpositions makes it ...
