相对论
相对论是关于时空和引力的基本理论，主要由阿 尔伯特·爱因斯坦创立，依据研究的对象不同分为 狭义相对论和广义相对论。相对论的基本假设是相 对性原理，即物理定律与参照系的选择无关。 狭义相对论和广义相对的区别是，前者讨论的是 匀速直线运动的参照系（惯性参照系）之间的物理 定律，后者则推广到具有加速度的参照系中（非惯 性系），并在等效原理的假设下，广泛应用于引力 场中。相对论极大地改变了人类对宇宙和自然的 “常识性”观念，提出了“同时的相对性”、“四 维时空”、“弯曲时空”等全新的概念。它发展了 牛顿力学，推动物理学发展到一个新的高度。

三、课后“静思2分钟”大有学问
我们还要注意课后的及时思考。利用课间休息时间，在心中快速把刚才上课时刚讲过的一些关键思路理一遍，把老师讲解的题目从题意到解答整个过程 详细审视一遍，这样，不仅可以加深知识的理解和记忆，还可以轻而易举地掌握一些关键的解题技巧。所以，2分钟的课后静思等于同一学科知识的课后 复习30分钟。

relativity n. 相对性 Switzerland 瑞士 Nobel 诺贝尔 Princeton 普林斯顿 uuclear adj. 核能的 weapon n. 武器 conclusion n. 结论 false adj. 错的
一、释疑难
对课堂上老师讲到的内容自己想不通卡壳的问题，应该在课堂上标出来，下课时，在老师还未离开教室的时候，要主动请老师讲解清楚。如果老师已经 离开教室，也可以向同学请教，及时消除疑难问题。做到当堂知识，当堂解决。
二、补笔记
上课时，如果有些东西没有记下来，不要因为惦记着漏了的笔记而影响记下面的内容，可以在笔记本上留下一定的空间。下课后，再从头到尾阅读一遍 自己写的笔记，既可以起到复习的作用，又可以检查笔记中的遗漏和错误。遗漏之处要补全，错别字要纠正，过于潦草的字要写清楚。同时，将自己对 讲课内容的理解、自己的收获和感想，用自己的话写在笔记本的空白处。这样，可以使笔记变的更加完整、充实。
