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.

世界现象是不可逆转的：我们记得过去而不是未来，窗户破裂并没有突然重新组装自己，而热量从热流到冷。自统计力学的早期以来，过去和未来之间的宏观区别引起了人们的奇迹。不可逆的热力学如何从经典和量子力学的时间可逆的显微镜方程中出现？ 如何根据力学来解释我们周围熵（无序）的不断增加？ Boltzmann，Gibbs，Maxwell，Einstein和其他许多人的基本作品解释了可观察到的现象，但即使在今天，基本的问题也引起了很多讨论和争议。
