KnowraEntropy as an arrow of timeLinked fromLinked fromThe 4 pages that link to Entropy as an arrow of time, each with the reason it gives.All 4Related 4Second law of thermodynamicsRelated: Entropy growth supplies a physical direction for processes such as mixing and heat diffusion.Irreversible processRelated: Irreversible processes give physical meaning to a preferred direction of time.Poincaré recurrence theoremRelated: Rare recurrence is compatible with typical entropy increase, but complicates claims of absolute irreversibility.Wheeler–Feynman absorber theoryRelated: Its low-entropy cosmological boundary condition is often invoked to distinguish radiation’s arrow from thermodynamic irreversibility.
