Lecture notes for a one-semester course in General Relativity. By Sean Carroll Ph.D

Lecture notes for the course on general relativity held in 1997 at the Physics Institute of NTNU, Trondheim by Petr Hadrava (the lecture notes themselves are Postscript files).

Highly recommendable collection of interconnected web pages that serve as an informal introduction to general relativity. While some mathematics is used, the focus is on the key ideas. By John Baez Ph.D (University of California at Riverside).

Lecture notes from a graduate course on Gravitation and Cosmology, taught by M. Cederwall Ph.D. at Chalmers University of Technology, Sweden in 2008.

A second year course including twelve lectures on special relativity taught by Michael Fowler Ph.D, beams professor at the University of Virginia in 1999. Includes lecture notes in HTML format (from Galilei transformations to relativistic mechanics, including some thoughts on general relativity) and problem sets. introducing special relativity and quantum mechanics. All of the lecture notes are posted online.
