Entropy is the measure of the disorder in a system that occurs over a period of time with no energy put into restoring the order. Zentropy integrates entropy at multiscale levels. Credit: Elizabeth ...

Entropy and information theory form a cornerstone of modern statistical and communication sciences. Entropy serves as a fundamental measure of uncertainty and information content in both physical and ...

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 ...

In my last report from Physics@FOM, I will talk about something I am truly not competent to discuss: “Holography, ADS/CFT and the emergence of gravity.” I realize that I am not always the sharpest ...

It’s notoriously difficult to take the temperature of really hot things. Whether it’s the roiling plasma in our Sun, the extreme conditions at the core of planets or the crushing forces at play inside ...

It feels so obvious that time moves forward that questioning it can seem almost pointless.

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

Information theory provides a mathematical framework for quantifying information and uncertainty, forming the backbone of modern communication, signal processing, and data analysis. Central to this ...
