As a source book, I recommend but do not require my book Gravitation and Cosmology (Wiley, 1972).
It is out of date, and I will not follow it closely. Grades will be based on 2 or 3 take-home problem sets
plus a final examination, which may or may not be take home. Anyone who wants can take or audit this
course, but although I will give a brief introduction to general relativity for the first week or so, it is
recommended that those who take this course for credit should already have some familiarity with general relativity.
