《相对论》在线课程总结 本课程深入探讨了狭义相对论，揭示了最大有限不变速度（光速）的存在所带来的诸多奇特效应。课程指出，在高速运动下，牛顿经典理论失效，传统的时空观念被打破，取而代之的是时空一体的新概念。我们将突破日常直觉，认识到许多本质上是相对论性的新现象，例如电动力学、相对论量子力学和量子场论。 课程将着重阐述同时性的概念，并辅以简单有效的实例进行直观讲解。此外，还将深入讨论不同参考系的重要性，并介绍规范场论的入门概念。所有推导均采用独特的“最小作用量原理”方法。 完成本课程后，学员将熟练掌握狭义相对论的核心内容。通过课程中学到的概念和推导方法，学员将能够轻松理解量子电动动力学、量子场论、标准模型等更高级的理论物理课程。课程还将对描述引力的几何理论——广义相对论——进行初步介绍。
In this course, the existence of maximal finite invariant speed (speed of light) leads to the many interesting consequences. The classical Newtonian theory breaks at high speed. The classical concepts of space and time breaks and the new concept of spacetime arises in which space and time are in the same footing. And our usual intuition breaks at this speeds. We observe lots of new phenomena which are relativistic in nature. Some examples are theory of Electrodynamics, Relativistic Quantum Mechanics, Quantum Field theory. Here, the theory of simultaneity is explained exclusively. Also, all the concepts are discussed very intuitively using very simple and effective examples. The importance of different frame of references have been discussed. Also, the introductory concept on gauge theory has been discussed. All the derivations are carry out using unique method - Principle of least Action. By completing this course, one will get experienced in the Special theory of relativity. By using the concepts and derivations taught in this lectures series, one can easily understand the advanced theoretical physics course like Quantum electrodynamics, Quantum field theory, Standard model etc. Also, the students will get some exposer to the General Theory of relativity which is the geometric description of the Gravity.
