All phenomena that behave differently in one time direction can ultimately be linked to the Second Law of Thermodynamics. This includes the fact that ice cubes melt in hot coffee rather than assembling themselves out of the coffee, that a block sliding on a rough surface slows down rather than speeding up, and that we can remember the past rather than the future. This last phenomenon, called the "psychological arrow of time", has deep connections with Maxwell's demon and the physics of information; In fact, it is easy to understand its link to the Second Law of Thermodynamics if one views memory as correlation between brain cells (or computer bits) and the outer world.

所有在一个时间方向上行为不同的现象最终都可以与热力学第二定律联系起来。这包括冰块在热咖啡中融化而不是从咖啡中自己组合出来，在粗糙的表面上滑动的冰块减慢而不是加速，以及我们能记住过去而不是未来。事实上，如果人们把记忆看作是脑细胞(或计算机比特)和外部世界之间的联系，那么就很容易理解它与热力学第二定律的联系。

Current research focuses mainly on describing the thermodynamic arrow of time mathematically, either in classical or quantum systems, and on understanding its origin from the point of view of [[cosmology|cosmological]] [[boundary conditions]].
