Having just read the thread https://www.physicsforums.com/showthread.php?t=39069 I have a question regarding somethinf mentioned there. It's been quite some time since I found a copy of Jared Diamond's Guns, Germs, & Steel. Way back when, I began reading it, and was astounded by the many errors and assumptions. So much so, that I began taking notes. However, I quickly ended up taking so many notes that I simply gave it up as a complete waste of time. Has anyone else had a look at this book? If so, did you find it worthwhile? Did you find it a well-considered piece of writing, or an attempt to justify an opinion already devoutly accepted by the author, or something else? In short... what did you think of it?
