更真实的是不同的
More Really is Different
摘要：
1972年，P.W.安德森提出“更多即不同”，这意味着复杂的物理系统可能会表现出无法仅根据控制其微观组成的定律来理解的行为。我们加强这一主张证明，许多宏观可观察到的性质，一类简单的物理系统（无限周期伊辛格）一般不能从微观描述。这提供了证据表明，紧急行为发生在这样的系统，并表明，即使一个'万有理论'管理所有微观相互作用被发现，宏观秩序的理解可能需要额外的见解。
英文摘要：
In 1972, P.W.Anderson suggested that `More is Different', meaning that complex physical systems may exhibit behavior that cannot be understood only in terms of the laws governing their microscopic constituents. We strengthen this claim by proving that many macroscopic observable properties of a simple class of physical systems (the infinite periodic Ising lattice) cannot in general be derived from a microscopic description. This provides evidence that emergent behavior occurs in such systems, and indicates that even if a `theory of everything' governing all microscopic interactions were discovered, the understanding of macroscopic order is likely to require additional insights.
