The Bumper Book of Technical Boobs 
Humorous examples of accidental (and humorous) errors in technical descriptions. Most of the gems on the following pages were, thankfully, picked up at the editing stage. One or two slipped through into printed books; some didnÕt even get as far as first draft stage. We have wondered for a long time about the mentality of the people who write this sort of thing; now you, too, can sit at your desk and try to figure out what these technical authors (yes, they actually get paid for this!) and engineers are on, where they got it from and whether they will give you some.
