He wrote it with the graduate student of 35 years ago in mind.

Yes, well I _was_ a graduate student, in physics, 34 years ago. I purchased his book in 1973 or 74 when it became apparent I would be unable to take the course on GR, due to scheduling conflicts (my dissertation necessarily took precedence). Biblophiles of the world, unite!

Not true. I don't ever remember the underlying geometry being discussed in class, or anywhere, prior to my purchasing MTW in 1997 or so (due to suggeestions on this newsgroup). Certainly Riemannian geometry was not in the typical physics curriculum when Weinberg's book was written, _except_ in courses on GR. The fact that MTW was also on the course list speaks volumes....
