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 ...

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 ...

In a recent paper, SFI Professor David Wolpert, SFI Fractal Faculty member Carlo Rovelli, and physicist Jordan Scharnhorst examine a longstanding, paradoxical thought experiment in statistical physics ...

I have always felt connected to the thermodynamic principle of entropy. I believed that my body at rest demonstrated the concept perfectly—and I now know that to be true, but not at all in the way ...

Time is a straightforward concept - or is it? The passing of minutes and years isn't as easy to explain as many assume.
