摘要

Darwin concludesThe Origin of Specieswith a splendid one-phrase poem,From so simple a beginningendless forms most beautiful and most wonderfulhave been, and are being, evolved.Darwin's “simple beginning” may be identified, in today's terminology, withdissipation—evolution's basic fuel. All the rest is commentary—or, more precisely, corollary.One can aptly apply Darwin's phrase to another kind of “simple beginning,” from which as well “endless forms most beautiful and most wonderful have been, and are being, evolved.” What I have in mind is a concept that is apparently the very antithesis of dissipation, namely, physics' fundamental assumption ofinvertibility—or “microscopic reversibility.” To paraphrase Dobzhansky, no sensible step can be taken today in information, communication, and computer sciences, as well as in fundamental physics, except in the light of invertibility.
机译：达尔文用一首精彩的一句诗作为《物种起源》的结尾，从如此简单的开始，就发展出了最美丽，最奇妙的无尽形式。在今天的术语中，达尔文的“简单开始”可以被消散掉，而这正是进化的基本动力。其余的全部都是评论，或者更确切地说是推论。一个人可以恰当地将达尔文的短语应用到另一种“简单的开始”，从中也可以“演化出最美丽，最美妙的无尽形式”。我想到的是一个显然与耗散相反的概念，即物理学对可逆性的基本假设，即“微观可逆性”。用多布赞斯基的话来说，除了可逆性之外，今天在信息，通信和计算机科学以及基础物理学中都不能采取明智的措施。
