FYI, there are a number of papers that did very rigorous derivations along this line years before math pages existed. While I generally have a good opinion of Kevin Brown (author of mathpages), there are times when he over philosophizes and over complicates things that can be treated much more simply. I think the single best free online intro to GR is Sean Carroll’s lecture notes.m4r35n357 said:I have to be perfectly honest here, I haven't checked this (lack of stamina), but thought I'd post it for awareness.
From the Field Equations to the Kruskal Metric
Tyre-kicking of the highest order!
To put it bluntly, Carroll's notes are just too hard, and too theoretical for my taste. I think the only part I understood properly was the effective potential orbit stuff. Mathpages suits me because it is like a giant set of worked examples, which I think is necessary if you are not surrounded by professors, textbooks and other students.PAllen said:FYI, there are a number of papers that did very rigorous derivations along this line years before math pages existed.
