计算机有时间箭头吗？
Does a Computer have an Arrow of Time?
摘要：
在[Sch05a]中，有人认为玻尔兹曼的直觉是正确的，即时间的心理箭头必然与热力学箭头一致。舒尔曼给出了这种联系的明确的物理机制，基于大脑可以表示为计算机，以及计算过程的某些热力学性质。[94]提出了类似的，如果简短，论点。本文的目的是批判性地审查支持之间的联系热力学和时间箭头的计算机。舒尔曼和霍金提出的主要论点将被证明是失败的。它将表明，任何计算过程，可以发生在一个熵增加的宇宙，同样可以发生在一个熵减少的宇宙。这个结论并不自动意味着心理箭头可以与热力学箭头背道而驰。将简要讨论两个箭头对齐的一些替代可能的解释。
英文摘要：
In [Sch05a], it is argued that Boltzmann's intuition, that the psychological arrow of time is necessarily aligned with the thermodynamic arrow, is correct. Schulman gives an explicit physical mechanism for this connection, based on the brain being representable as a computer, together with certain thermodynamic properties of computational processes. [Haw94] presents similar, if briefer, arguments. The purpose of this paper is to critically examine the support for the link between thermodynamics and an arrow of time for computers. The principal arguments put forward by Schulman and Hawking will be shown to fail. It will be shown that any computational process that can take place in an entropy increasing universe, can equally take place in an entropy decreasing universe. This conclusion does not automatically imply a psychological arrow can run counter to the thermodynamic arrow. Some alternative possible explana- tions for the alignment of the two arrows will be briefly discussed.
