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 ...

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 ...

A deep understanding of the irreversibility of the arrow of time cannot ignore the quantum nature of the world that surrounds us. A deep understanding of the irreversibility of the arrow of time ...

For more than a century and a half of physics, the Second Law of Thermodynamics, which states that entropy always increases, has been as close to inviolable as any law we know. In this universe, chaos ...

If someone asked you “If, in some cataclysm, all of scientific knowledge were to be destroyed, and only one sentence passed on to the next generation of creatures, what statement would be most ...

Soon after the discovery of the second law of thermodynamics, James Clerk Maxwell illustrated the probabilistic nature of the law with a gedanken experiment, now known as Maxwell’s demon 1,2. He ...

Benjamin Franklin famously said, “In this world nothing can be said to be certain, except death and taxes,” but anyone who’s ever taken an introductory Physics class knows that there’s something more ...
