Entropy is a scientific concept that is most commonly associated with a state of disorder, randomness, or uncertainty. The term and the concept are used...

In information theory, the entropy of a random variable is the average level of "information", "surprise", or "uncertainty" inherent to the variable's...

Research concerning the relationship between the thermodynamic quantity entropy and both the origin and evolution of life began around the turn of the...

The entropy unit is a non-S.I. unit of thermodynamic entropy, usually denoted "e.u." or "eU" and equal to one calorie per kelvin per mole, or 4.184 joules...

In information theory, an entropy coding (or entropy encoding) is any lossless data compression method that attempts to approach the lower bound declared...

Entropy production (or generation) is the amount of entropy which is produced during heat process to evaluate the efficiency of the process. Entropy is...

entropy is a sociological theory that evaluates social behaviours using a method based on the second law of thermodynamics. The equivalent of entropy...

The min-entropy, in information theory, is the smallest of the Rényi family of entropies, corresponding to the most conservative way of measuring the unpredictability...

A thermodynamic free entropy is an entropic thermodynamic potential analogous to the free energy. Also known as a Massieu, Planck, or Massieu–Planck potentials...

In chemical kinetics, the entropy of activation of a reaction is one of the two parameters (along with the enthalpy of activation) that are typically...

entropy of X. The above definition of transfer entropy has been extended by other types of entropy measures such as Rényi entropy. Transfer entropy is...

Differential entropy (also referred to as continuous entropy) is a concept in information theory that began as an attempt by Claude Shannon to extend...

In thermodynamics, entropy is a numerical quantity that shows that many physical processes can go in only one direction in time. For example, cream and...

In information theory, the cross-entropy between two probability distributions p {\displaystyle p} and q {\displaystyle q} , over the same underlying...

Rényi entropy is a quantity that generalizes various notions of entropy, including Hartley entropy, Shannon entropy, collision entropy, and min-entropy. The...

The entropy of entanglement (or entanglement entropy) is a measure of the degree of quantum entanglement between two subsystems constituting a two-part...

In computing, entropy is the randomness collected by an operating system or application for use in cryptography or other uses that require random data...

Entropy is a 1999 film directed by Phil Joanou, starring Stephen Dorff and featuring the Irish rock band U2. A largely autobiographical film about director...

Entropic gravity, also known as emergent gravity, is a theory in modern physics that describes gravity as an entropic force—a force with macro-scale homogeneity...

mathematical theory of probability, the entropy rate or source information rate is a function assigning an entropy to a stochastic process. For a strongly...
