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 production lies at the heart of non-equilibrium thermodynamics, a field that examines systems away from equilibrium where continuous energy flows and irreversible processes dominate. In such ...

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 ...

One of the most fundamental rules of physics, the second law of thermodynamics, has for the first time been shown not to hold for microscopic systems. The demonstration, by chemical physicists in ...

Pity the poor thermodynamics student of the future. As difficult as thermo can be for budding engineers to learn, it is going to get a lot more complicated if a recently published theory is true.

Entropy is behind one of the most fundamental laws of physics. Entropy is surely one of the most perplexing concepts in physics. It’s variously described as a measure of a system’s disorder - or as ...
