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 ...

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 ...

How it works When laser light passes through a cavity filled with atoms, part of it can do useful work. In this example the work is charging a quantum battery (top). The rest of the light turns into ...

Recently, a team of researchers made headlines for a stunning announcement: a theoretical breakthrough that expanded our understanding of the first law of thermodynamics. But to understand that result ...

A deep understanding of the irreversibility of the arrow of time cannot ignore the quantum nature of the world that surrounds us. A deep understanding of the irreversibility of the arrow of time ...

WASHINGTON, Sept. 6, 2023 – Though a cornerstone of thermodynamics, entropy remains one of the most vexing concepts to teach budding physicists in the classroom. As a result, many people oversimplify ...
