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...

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...

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...

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...

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

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...

arrow of time can only be explained by appealing to low entropy conditions shortly after the Big Bang, although the explanation for the low entropy of...
