Adam Marsh's "Mathematics for Physics" is now available online, with Subodh Patil highlighting its algebraic topology section as a useful primer for Nakahara's work. There is debate over the book's title, which some find misleading, arguing it focuses more on geometry and topology than on broader mathematical methods for physics. Discussions explore the relevance of algebraic topology in physics, with examples including topological defects, Yang-Mills theory, and string theory. Participants express skepticism about the practical applications of algebraic topology in physics, seeking specific examples from the book. The conversation also touches on the publication status of Nakahara's book, with speculation about delays in its release. Overall, the thread emphasizes the need for clarity in mathematical texts and the importance of understanding the specific applications of mathematical concepts in physics.
