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 also increases in initially ordered quantum systems until it reaches a final state of disorder. Entropy and the direction of time Equating 'entropy' with 'disorder' is not entirely correct.

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 ...

Entropy is one of the most useful concepts in science but also one of the most confusing. This article serves as a brief introduction to the various types of entropy that can be used to quantify the ...

Looking back a variety of distances corresponds to a variety of times since the Big Bang. Entropy has always increased from any moment to the next, but that doesn't mean that the Big Bang began with ...

What is the concept of entropy? Embedded-system applications that exploit entropy. How to implement entropy. What sources of entropy are available? Computers are designed to be predictable. Under the ...
