A short and sweet textbook on Einstein’s theory of relativity, and more.
Download it here. (Previous versions are here.)
Learning relativity was a long journey for me. From college courses to self-study, I needed many resources to fully understand the theory, and I eventually felt that I could explain it better and with fewer words than other textbooks. Here is the result.
Vector calculus and classical mechanics. Basically, a standard freshman or sophomore physics curriculum in the US. Some knowledge of linear algebra and electromagnetism will also help, although Appendix A develops the necessary linear algebra.
I will write an exercise solutions manual if there is enough interest.
