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 of liquid Na: the present calculation (red) and experimental data (black). The entropy value is normalized by the gas constant R. T 1 denotes the melting temperature. Osaka, Japan - A ...

One of the enormous conceptual ideas that came along with Einstein's theory of relativity was the surprise that time itself, long considered fundamental and universal, is actually relative. Different ...

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 ...

In all of physical law, there’s arguably no principle more sacrosanct than the second law of thermodynamics — the notion that entropy, a measure of disorder, will always stay the same or increase. “If ...

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 ...
