1. The February and July 1984 columns listed several excellent references for quick calculations. Edward Purcell edits the monthly "Back of the Envelope" column in the American ]ournal of Physics. Douglas Wofstadter's "Metamagical Themas" column in the May 1982 Scientific American is subtitled "Number numbness or why innumeracy may be just as dangerous as illiteracy"; it is reprinted with a postscript in his book Metamagical Themas published by Basic Books in 1985.
2. A First Course in Mathematical Modeling by Frank Giordano and Maurice Weir was published by Wadsworth in 1985. It describes many facets of mathematical "common sense" (which isn't common enough). Chapter 7 covers "Dimensional Analysis"; it is especially relevant to quick calculations.
