Entropy also increases in initially ordered quantum systems until it reaches a final state of disorder. Entropy and the direction of time Equating 'entropy' with 'disorder' is not entirely correct.

Science popularization has its legends and heroes, just like any other field, though I’ve heard no plans as yet to open a Hall of Fame. Should that day come, one of the first inductees would ...

A groundbreaking new method developed at the University of Osaka calculates the entropy of liquids using a non-empirical approach, requiring only the atomic species as input. The paper is published in ...

Paul M. Sutter is an astrophysicist at The Ohio State University, host of Ask a Spaceman and Space Radio, and author of "Your Place in the Universe" (2018). Sutter contributed this article to ...

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 ...

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 ...

The following is an extract from our Lost in Space-Time newsletter. Each month, we hand over the keyboard to a physicist or two to tell you about fascinating ideas from their corner of the universe.
