First four lecture notes are derived from the lecture notes of prof. R. Shankar, Yale University, and are intended to provide a concise overview of the Special Theory of Relativity. The notes cover the fundamental concepts, mathematical formulations, and key implications of the theory, including time dilation, length contraction, and the invariance of the speed of light.
The lecture notes are structured to facilitate understanding of the principles of relativity, starting from the postulates of special relativity and progressing through the derivation of the Lorentz transformations. The notes also explore the consequences of these transformations on physical phenomena and provide examples to illustrate the effects of relativistic motion.
Official Lecure notes for spatial theory of relativity can be found at here, which were a chunk of lectures given for the course of mechanics which can be found here.
