"Computer Science Unplugged" by Tim Bell, Ian Witten, and Mike
Fellows. I found a copy on the web at

Comments:
A deeper piece of computer science unplugged is Ronald W. Doerfler's Dead Reckoning : Calculating Without Instruments. It describes a great number of efficient methods of mental calculation, all with references. Some notable authors cited are Donald Knuth, Richard P. Feynman, and Douglas Hofstadter.
