The second law of thermodynamics says, in simple terms, entropy always increases. This principle explains, for example, why you can't unscramble an egg. When you purchase through links on our site, we ...

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 surely one of the most intriguing and misunderstood concepts in all of physics. The entropy of the universe must always increase – so says the second law of thermodynamics. It’s a law that ...

As physicists extend the 19th-century laws of thermodynamics to the quantum realm, they’re rewriting the relationships among energy, entropy and information. In his 1824 book, Reflections on the ...
