Feynman’s advice to W&M student resonates 45 years later (2020)
Related question: I am reading a book by an author whom I know socially. The book is very good, but I have noticed a few minor typos. I also noticed that one example is explained backwards — that is, it mixes up the causes and effects for two phenomena. I have not independently researched the phenomena, but based on the earlier description (which is logical and I believe to be correct), the conclusion of a section is clearly mistaken.<p>Is it appropriate or helpful to point out any of these issues? The book came out a couple years ago, and I imagine other people who know the author may have pointed them out already. I don't want to make him feel bad (no one likes the bearer of bad news), but if it were me I would want to be told so that future print runs and digital editions could be corrected. (The book is popular and will likely remain relevant for years or even decades.)<p>Perhaps I should shoot him an email from an anonymous email address?
