General relativity forms a cornerstone of modern physics. It lays the theoretical foundation for black holes, neutron stars, and other exotic astrophysical objects; for gravitational-wave astronomy; and for the evolution of the universe itself. It is a theory of great aesthetical beauty and, with the global positioning system, has even found an important role in a technological application that many of our students use on a daily basis. It is surprising, then, that general relativity has never formed a cornerstone of physics education. Thomas Moore's excellent new textbook A General Relativity Workbook represents an innovative addition to a growing body of general relativity textbooks aimed at undergraduate students and may well help encourage more physics departments to offer courses on the subject.
Traditionally, general relativity has been taught most commonly in elective, graduate-level courses. Accordingly, most of the classic textbooks on the subject, including Gravitation by Misner, Thorne, and Wheeler...
