A measure of the amount of information and noise present in a signal. Originally a tongue in cheek coinage, has fallen into disuse to avoid confusion with thermodynamic entropy. (noun)
The tendency of a system that is left to itself to descend into chaos. (noun)
Examples of word entropy
A typical rebuttal is to suggest that information entropy and thermodynamic entropy are unconnected, citing the apocryphal story that Shannon picked the term entropy because “nobody understands what it means”.
In Über die bewegende Kraft der Wärme (1865) he introduced the term entropy, stating that the entropy of the universe tends to increase.
Rudolf J.E. Clausius also introduced (1850) a quantitative measure of irreversibility which he termed entropy, and he posited the so-called second law of thermodynamics by which for a closed physical system the total entropy of the system cannot decrease in time but only increase or at most remain constant.
Fork in the Road, is entirely about his electric car, which he calls the entropy said: "This video made me smile and be happy, it's great to see people and robots getting along! ..." idontlikewords said: "I think what the author is getting at by bringing up the difference between an advertising medium an ..."
It didn’t help that von Neuman and Shannon started using the term entropy for a formula in information theory that looked a lot like Boltzmann’s expression for entropy.
