Exactly 200 years ago, a French engineer introduced an idea that would quantify the universe’s inexorable slide into decay. But entropy, as it’s currently understood, is less a fact about the world ...

By Partha Sinha Entropy fascinates because it announces itself. It spreads, decays and disperses. It makes noise. Like Kali, ...

Entropy is something very peculiar. Let's remember that all physical quantities are conserved: In any closed system, energy is conserved, matter is conserved, momentum is conserved. That means that ...

Entropy, the amount of molecular disorder, is produced in several systems but cannot be measured directly. A new equation sheds new light on how entropy is produced on a very short time scale in laser ...

Entropy. Randomness. Disorder. Think of it as the universe’s tendency to move from ordered to disordered forms. It is a scientific concept of something that increases over time and something that is ...

For more than a century, gravity has been the stubborn outlier in physics, resisting every attempt to merge Einstein’s smooth space-time with the jittery world of quantum mechanics. A new wave of ...
