Entropy is one of the few quantities in the physical sciences that require a particular direction for time, sometimes called an arrow of time. As one...

Entropy may be one of the few processes that is not time-reversible. According to the statistical notion of increasing entropy, the "arrow" of time is...

The second law states that any closed system follows the arrow of time, meaning its entropy never decreases. Applying this idea to the entire universe...

direction of progress, sometimes called an arrow of time. As time progresses, the second law of thermodynamics states that the entropy of an isolated system...

an absolute concept of eternity has real application for fundamental laws of physics; compare the issue of entropy as an arrow of time. Eternity as infinite...

arrow of time is a concept concerning the "one-way direction" or "asymmetry" of time. Arrow of time may also refer to: Entropy (arrow of time) "Arrow...

direction of time but rarely or never in the opposite direction, such as entropy increasing in an isolated system, defines what physicists call an arrow of time...

bits needed to identify an event from a set of possibilities between two probability distributions Entropy (arrow of time) Entropy encoding – a coding scheme...

cannot decrease with time, as they always tend to arrive at a state of thermodynamic equilibrium, where the entropy is highest. Entropy is therefore also...

the arrow of time from radiation is a more general case of the thermodynamic arrow of time. In this chapter Price tackles the problem of why entropy was...

{\displaystyle T:t\mapsto -t.} Since the second law of thermodynamics states that entropy increases as time flows toward the future, in general, the macroscopic...

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

backward. But entropy is a strictly one-way affair – it's always increasing with the passage of time. Hence the expression, 'Time's Arrow'".: 53  This...

physics, maximum entropy thermodynamics (colloquially, MaxEnt thermodynamics) views equilibrium thermodynamics and statistical mechanics as inference processes...

(rather than focusing) in time (see light cone); Entropic arrow of time: according to the second law of thermodynamics an isolated system evolves toward...

psychological arrow of time is intertwined with the thermodynamic arrow of time. Hawking's third and final arrow of time is the cosmological arrow of time: the...

exist at the same time. Chapter 6, "Chance and the Arrow", asks, "Does time have an arrow?" The reader discovers that the laws of physics apply moving...

Thermodynamic arrow of time – distinguished by the growth of entropy. Cosmological arrow of time – distinguished by the expansion of the universe. With time, entropy...

(increase in entropy). His proposed explanation for the arrow of time is based on ideas that go back to Ludwig Boltzmann, an Austrian physicist of the 1870s...

realities such as Alpha Centurion, an alternate version of Batgirl, and Triumph suddenly start appearing in the DC Universe. A wave of entropy then moves...

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