The phenomena of the world are irreversible: we remember past and not future, a broken window does not suddenly reassemble itself, and heat flows from hot to cold. Since the early days of statistical mechanics the macroscopic distinction between past and future has caused wonder. How does irreversible thermodynamics emerge from time reversible microscopic equations of classical and quantum mechanics? How can one explain the constant increase of entropy (disorder) around us on the basis of mechanics? The fundamental works of Boltzmann, Gibbs, Maxwell, Einstein and many others have explained the observable phenomenon, but the underlying questions have provoked much discussion and controversy, even today.

世界的现象是不可逆转的：我们记得过去而不是未来，一扇破碎的窗户不会突然重新组装起来，热量从热到冷。从统计力学诞生之初，过去和未来之间的宏观区别就引起了人们的好奇。不可逆热力学是如何从经典和量子力学的时间可逆微观方程中产生的？ 如何在力学的基础上解释我们周围熵的不断增加（无序）？玻尔兹曼、吉布斯、麦克斯韦、爱因斯坦和许多其他人的基本工作已经解释了可观察到的现象，但即使在今天，潜在的问题也引发了许多讨论和争议。
