课程名称：理解现代物理学 I：相对论与宇宙学 课程概述： 20世纪被称为物理学的世纪。过去120年以来，空间、时间、能量、熵和粒子等概念得到了更深入的理解。新的思维范式，如相对论和量子力学应运而生。 本课程是理解现代物理学系列的第一门课程，重点介绍特殊相对论、广义相对论和宇宙学。我们将探讨以下内容：(i) 空间和时间如何相对于观察者而存在，并统一成更为基础的时空结构；(ii) 时空为何不是绝对的，而是按照物质的存在而弯曲，重力如何因此而产生；(iii) 理解整个宇宙演化的框架，以及其与空间和物质起源、宇宙命运等问题的关系。 注意：带有(*)标记的视频为可选内容，提供补充信息，但不在学习目标或作业问题中。您可以根据自己的选择观看这些视频。 课程大纲： - 名称：特殊相对论：空间与时间的相对性 - 描述： - 名称：特殊相对论：长度、同时性与洛伦兹变换 - 描述： - 名称：特殊相对论：几何、能量与动量 - 描述： - 名称：广义相对论 - 描述： - 名称：宇宙学 - 描述：

Course Overview: https://youtu.be/xyF-MmGNxd0 The 20th century was known as the century of physics. In the past 120 years, concepts such as space, time, energy, entropy and particles were understood to much deeper levels. New paradigms of thinking such as relativity and quantum mechanics emerged. This course is the first course in the Understanding Modern Physics series, which covers an introduction to special relativity, general relativity and cosmology. We will find: (i) How space and time are relative to observers, and unified into a more fundamental construction of spacetime; (ii) Why the spacetime is not absolute, but rather curves in response to matter, and how gravity emerge as a result of such spacetime curvature; and (iii) What is the framework to understand the evolution of the whole universe, and how that is related to problems such as the origin of space and matter, and the fate of our universe.
