Hi everyone. Schutz recently released a 2nd edition of his book "A First Course In General Relativity". Has anyone read this edition? Is it worth getting the 2nd edition, or is the 1st fine? The library has the first edition and that's 390 pages. The second edition is 410 pages. From the editorial reviews on amazon.com : https://www.amazon.com/First-Course...054/ref=sr_1_2?ie=UTF8&qid=1249676182&sr=8-2# it looks like the main changes are in the applications of GR to cosmology etc. I am a mathematics major so I do not intend going into any GR related research, so is this a big deal? Thanks.
