In Zee's Gravity in a Nutshell P107, 13 lines from the bottom, for a sphere of radius a, should the curvature G be 1/(a^2) instead of a^2?

Yes, it seems that it is a misprint.

Thanks. Since we are on this book, I have another question: on page 306, lines 9 and 11 from the top, should B(t,r) and A(t,r) have square roots on them?
