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 ...

Sometimes, randomness is intentionally introduced for security reasons, and that’s accomplished by collecting entropy, which is a measure of unpredictability.

Entropy is a confusing concept, but it is also extremely useful for quantifying the properties of complex systems like the human brain. This article attempts to demystify the term.

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 ...

What Entropy Is, and Is Not To judge from the writings of C.R Snow, entropy and the second law of thermodynamics were once indelicate subjects. Now things have changed, and on the cocktail party ...

Entropy is a physical law which states that, in a closed system, disorder always increases. Evolution selects for "anti-entropic" adaptations which expend energy in order to maintain homeostasis.
