KnowraLoschmidt's paradoxLinked fromLinked fromThe 7 pages that link to Loschmidt's paradox, each with the reason it gives.All 7Related 4Compared with 3Ludwig BoltzmannCompared with: It exposed a central difficulty in deriving the H-theorem’s time direction from mechanics.Irreversible processRelated: It exposes the gap between reversible microscopic dynamics and irreversible thermodynamics.Poincaré recurrence theoremRelated: Recurrence sharpens questions about how irreversible thermodynamic trends arise from reversible dynamics.Arrow of timeCompared with: It exposes the tension between time-symmetric mechanics and entropy's observed growth.Maxwell's demonRelated: It shares the demon’s challenge: how can entropy increase emerge from reversible molecular laws?Boltzmann's entropy formulaRelated: It tests how a statistical state-count formula can support an arrow of time.Entropy as an arrow of timeCompared with: Reversing every particle velocity would make entropy decrease, exposing the need for statistical assumptions.
