It is one of the most important laws of nature that we know: The famous second law of thermodynamics says that the world gets more and more disordered when random chance is at play. Or, to put it more ...

Thermodynamics and statistical physics provide complementary frameworks for describing many-particle systems. Thermodynamics identifies a small set of macroscopic variables—energy, entropy, volume, ...

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 ...

FOR THOSE READERS who like short book reviews, let me assist you. "Four Laws That Drive the Universe," by Peter Atkins is an outstanding introduction to thermodynamics. This brief book converts ...

Statistical mechanics is one of the pillars of modern physics. Ludwig Boltzmann (1844–1906) and Josiah Willard Gibbs (1839–1903) were its primary formulators. They both worked to establish a bridge ...

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 ...

The second law of thermodynamics is one of those puzzling laws of nature that simply emerges from the fundamental rules. It says that entropy, a measure of disorder in the Universe, must always ...

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 ...

A new analysis of the “Boltzmann brain” paradox suggests our memories and sense of reality could, in theory, be random ...
