Nernst's theorem—a general experimental observation presented in 1905 that entropy exchanges tend to zero when the temperature tends to zero—has been directly linked to the second principle of ...

A tiny quantum machine can release light that is not simply wasted heat; some of that energy may still be useful for doing work. University of Basel physicists found that separating orderly, coherent ...

What is heat, and what is useful work if a machine consists only of an atom and light particles? In modern quantum technologies, this kind of question connects thermodynamics with quantum physics.

In seeming defiance of the second law of thermodynamics, nature is filled with examples of order emerging from chaos. A new theoretical framework resolves the apparent paradox Science has given ...

The theory of thermodynamics has helped us understand devices like engines for more than 200 years, but its mathematical foundations have always been a little too imprecise. Now, researchers are ...

Recently, there has been much progress in understanding the thermodynamics of quantum systems, even for small individual systems. Most of this work has focused on the standard case where energy is the ...

Picture Victorian London, but its skies are filled with airships. Steam-powered robots crowd the streets, mingling with people in top hats and petticoats. That type of retrofuturistic mash-up is the ...

Thermodynamics — the branch of physics dealing with heat and its relation to other forms of energy — is profound stuff. Rooted in the engineering realities of engines and air conditioners, it also ...

A CENTURY ago, two intellectual giants met to debate the nature of time. One was the French philosopher Henri Bergson, a superstar whose fans caused the first traffic jam on Broadway in New York as ...
