What's the dumbest mistake you've ever seen in a textbook?

My official Chemistry textbook I'm supposed to use to teach Chemistry omits the neutrino when describing beta decay. A problem? Well, considering that more than 99% of the particles in the universe ARE neutrinos, I'd have to say yes! You can't just ignore them!What's the dumbest mistake you've ever seen in a textbook?
Try teaching Calculus out of a 15-year old textbook with numerous mistakes.



That's what I'm stuck doing right now. It sucks. I'm having to make up my own problems and whatever as I go along, not to mention the textbook has the order so screwed up that I have to teach it in (logical) order, and not how the book presents it.



Oh lovely Saxon math books!!!What's the dumbest mistake you've ever seen in a textbook?

To the "questioner", that isn't really a mistake. neutrinos were left out of the book because it was a high school class, and neutrinos are beyond the scope of what they are learning (or at least that is what the authors supposed). If they included it they'd have to discuss the origin, different flavors, etc. And neutrinos certainly don't make up 99% of the particles in the universe.
