Loschmidt's paradox

Loschmidt's paradox points to a puzzling contradiction in thermodynamics and statistical mechanics. It suggests that while the second law of thermodynamics states that entropy (disorder) in an isolated system always increases, the fundamental equations of physics are reversible. If you could reverse time, the entropy would decrease, contradicting the irreversible nature of real processes. This raises questions about the nature of time, the direction of physical processes, and our understanding of entropy. Loschmidt's paradox emphasizes the tension between microscopic reversibility and macroscopic irreversibility in understanding physical phenomena.
