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 ...

A new theoretical study offers a possible explanation for how the Universe can grow more complex without violating the second law of thermodynamics. Using a quantum gravity framework called Gravity ...

According to the second law of thermodynamics, the total entropy of a closed process can increase or stay the same, but never decrease. The second law guarantees, for example, that an egg can wobble ...

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 ...

A challenge in materials design is that in both natural and manmade materials, volume sometimes decreases, or increases, with increasing temperature. While there are mechanical explanations for this ...
