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...

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...

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

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...

The Arrows of Time is a hard science-fiction novel by Australian author Greg Egan and the third part of the Orthogonal trilogy. The novel was published...

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

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...
