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 ...

A fundamental rule that determines the fate of the universe The second law of thermodynamics means hot things always cool unless you do something to stop them. It expresses a fundamental and simple ...

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 ...

The second law of thermodynamics is one of those puzzling laws of nature that simply emerges from the fundamental rules. It says that entropy, a measure of disorder in the Universe, must always ...

Exactly 200 years ago, a French engineer introduced an idea that would quantify the universe’s inexorable slide into decay. But entropy, as it’s currently understood, is less a fact about the world ...

Pity the poor thermodynamics student of the future. As difficult as thermo can be for budding engineers to learn, it is going to get a lot more complicated if a recently published theory is true.

One of the most fundamental rules of physics, the second law of thermodynamics, has for the first time been shown not to hold for microscopic systems. The demonstration, by chemical physicists in ...
