General relativity is one of the towering achievements of modern physics. Here is where we basically abandon tensors and get to grips with its physical implications - black holes, curved spacetime, time travel.... After each lecture I will link material to this page - so keep checking to see what is here (and hit reload to make sure you are getting the most up to date version!). These lecture notes are NOT a substitute for attending the lectures. But do look at them because I put them up AFTER the lecture, so I emphasise and try to find other ways of explaining any points which were obviously hard to get and I sort out any ambiguities of notation.
There is a highly recommended web sit of Sean Carroll's lecture notes on general relativity. I especially like his No-Nonsense Introduction to General Relativity. Only thing to watch is that he uses the opposite sign convention on his metric! His links are worth checking out as well. A very different approch (much more along the pure mathematics, differential geometry line) is an Introduction to Differential Geometry and General Relativity. But its got some good pictures in it.
There are also some fun relativity pages on the web
Popular science (non technical sites) include
spacetime wrinkles and
foundations. There are also some good visualisation sites like
falling into a
black hole and a
make your own orbits around a black hole (java applet
site). Good ways of visulasing GR are given in
riding the curvature of spacetime
Getting a bit more technical but still very visual try
geometry around black
holes and dip into the (still very low level) book on
special and general relativity.
