The discussion centers on the suitability of a specific book for learning about tensors, particularly in preparation for a course in general relativity (GR). While the book has received good reviews, participants express skepticism about its depth and relevance for GR, suggesting it may not provide the rigorous introduction needed. Instead, they recommend using standard GR texts, specifically mentioning Bernard Schutz's "A First Course in General Relativity," which is praised for its clear, modern approach to tensors suitable for physics undergraduates. Participants emphasize the importance of multiple textbooks to grasp both the mathematical and physical concepts of GR, noting that while Schutz covers the math well, additional resources like Hartle's book may provide better problem sets for understanding the physical concepts. Overall, the consensus is that investing in the recommended texts will be more beneficial than the original book in question.
