{{quote|The law that entropy always increases holds, I think, the supreme position among the [[Laws of science|laws of Nature]]. If someone points out to you that your pet theory of the [[universe]] is in disagreement with [[Maxwell's equations]] – then so much the worse for Maxwell's equations. If it is found to be contradicted by observation – well, these experimentalists do bungle things sometimes. But if your theory is found to be against the second law of thermodynamics I can give you no hope; there is nothing for it but to collapse in deepest humiliation.|Sir [[Arthur Stanley Eddington]], ''The Nature of the Physical World'' (1927)}}

我认为，熵总是增加的定律在自然定律中占有至高无上的地位。如果有人指出您的宇宙宠物理论与麦克斯韦方程不符，那么麦克斯韦方程就遇到麻烦了。如果发现与观察不符，那么，可能是这些实验学家搞砸了。但是，如果发现您的理论违反了热力学第二定律，那么就没有希望了。除了在深深的耻辱中崩溃，别无他法。
—亚瑟·斯坦利·爱丁顿爵士，《自然世界》（1927年）
{{quote|Clausius is the author of the sibyllic utterance, "The energy of the universe is constant; the entropy of the universe tends to a maximum." The objectives of continuum thermomechanics stop far short of explaining the "universe", but within that theory we may easily derive an explicit statement in some ways reminiscent of Clausius, but referring only to a modest object: an isolated body of finite size.|[[Clifford Truesdell|Truesdell, C.]], Muncaster, R.
