20190708长难句
【前文复习】
Since the days of Aristotle, a search for universal principles has characterized the scientific enterprise. In some ways, this quest for commonalities defines science. Newton’s laws of motion and Darwinian evolution each bind a host of different phenomena into a single explicatory frame work. In physics, one approach takes this impulse for unification to its extreme, and seeks a theory of everything—a single generative equation for all we see.
自亚里士多德的时代起，对普遍原理的探求就一直是科学事业的主要特征。在某些方面，寻找事物的共性也正是科学的定义/内涵。牛顿的运动定律和达尔文的进化论都是把很多不同现象纳入到一个单独框架来解释。在物理学上，有一种方法是将这种追求统一的冲动发挥到极点，它寻找一种万能的理论，即一种单一的能够解释我们所能看到的一切的通用公式。
【今日长难句】
It is becoming less clear, however, that such a theory would be a simplification, given the dimensions and universes that it might entail, nonetheless, unification of sorts remains a major goal.
【词的处理】
simplification / ˌsimplifiˈkeiʃn / n. 简化
given / ˈɡivn / prep. 考虑到
dimension / daiˈmenʃn; di- / n. 纬度
universe / ˈju:nivə:s; NAmE -və:rs / n. 宇宙；经验体系
entail / inˈteil / vt. 牵涉；须要
nonetheless / ˌnʌnðəˈles / adv. 尽管
unification /juːnifi'keiʃ(ə)n/ n. 统一，一致
【结构解析】
1. 本句前半句，it 为形式主语，真正的主语是：that such a theory would be a simplification.
2. given the dimensions and universes that it might entail 为前半句的修饰成分，其中难点在于“given”一词表“考虑到……”；that it might entail 为定语从句，修饰the dimensions and universes, 其中it之such a theory.
3. nonetheless之后为后半句，为主系表结构，即：unification of sorts /remains /a major goal.
【参考译文】
It is becoming less clear, however, that such a theory would be a simplification, given the dimensions and universes that it might entail, nonetheless, unification of sorts remains a major goal.
然而，考虑到/鉴于这样的一种理论所涉及的维度和范畴，它是否还算是一种简化就变得越来越说不清楚了。尽管如此，寻找万物的统一性仍然是一个主要目标。
【明日预告】
This tendency in the natural sciences has long been evident in the social sciences too. Here, Darwinism seems to offer justification, for if all humans share common origins it seems reasonable to suppose that cultural diversity could also be traced to more constrained beginnings.
