A user is seeking an online study partner for "Gravity" by James B. Hartle, indicating they are self-studying the material. Another participant, Matt, is using the book as a supplement for an introductory general relativity (GR) class and has read several chapters, finding the treatment of special relativity clear but wishing for more detailed explanations of example problems. They discuss the challenges of introductory texts in GR, with one user expressing frustration at the brevity of explanations. Interest in forming study partnerships grows, with multiple users expressing willingness to collaborate and share resources, including a course curriculum and a free online GR book that offers an alternative perspective to Hartle's treatment. The conversation highlights the need for comprehensive resources in learning GR and the value of collaboration among self-learners.
