It's amazing how many of these I've read. I didn't think I spent that much time at it outside techincal reading.
One of my favorites: "On Food and Cooking" - McGee. A great book that deals with the history and chemistry of cooking. It's about how to understand the interaction of ingredients and how they act under heat. Why things work.
The Lord of the Rings" was terrific and is one of the few sets I ever read more than once. (about had to to keep up with it)
"Rifle Accuracy Facts" - Vaughn, recently deceased I have read. Just a great book about guns in general.
Then, anything from Peter H Anderson. These deal with electronics engineering and are very hands on for a variety of new products. Great stuff for anyone who wants to learn on thier own. From discretes, to microcontrollers, to microprocessors, real world interfacing, Basic Stamp Processors, etc. He even has 2 books that show how to use a parallel port on a PC to either collect or output data or control. He has a website that has all sorts of kits you can buy. 100% of the proceeds go to the E-Engineering dept students at Morgan St U in MD. http://www.phanderson.com
. Most of the site is handled by students. If my memory serves me (and it seldom does) something like more than 90% of his students take every single elective He offers during a year. Nice guy too.
