You may disagree but most books I read on math, or subjects that require math, contain a sizable amount of BS. Not in the sense of containing things that are wrong but in the sense of containing things that are there for the author to show off rather than for the reader to comprehend the subject matter. I read books to learn about something that I didn't know about before. So I as a reader can't distinguish between the important stuff and the 'fluff'. The author has to do that for me. The best texts do that rigorously but the bulk does not, unfortunately.
