Entropy isn't well understood in systems that aren't at equilibrium, but a new experiment shows a non-equilibrium phenomenon that actually depends upon entropy. Entropy, the measure of disorder in a ...

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 ...

It is one of the most important laws of nature that we know: The famous second law of thermodynamics says that the world gets more and more disordered when random chance is at play. Or, to put it more ...

Entropy is one of the most useful concepts in science but also one of the most confusing. This article serves as a brief introduction to the various types of entropy that can be used to quantify the ...

For more than a century, gravity has been the stubborn outlier in physics, resisting every attempt to merge Einstein’s smooth ...

Entropy is the process of losing energy and this can apply to physics and social systems alike. JamesBrey/iStock via Getty Images Life is full of small decisions: Should I pick up that sock on the ...

PROVIDENCE, R.I. [Brown University] -- Entropy, the measure of disorder in a physical system, is something that physicists understand well when systems are at equilibrium, meaning there's no external ...
