Description
Pocket Ref, first published in 1989 and now in its fourth edition (2010), has 864 pages, including beam strength for 76 wood species, weights of materials, element tables, floor joist spans, concrete mixtures, solvent properties, perpetual calendar, and sections on automotive, physical constants, electronics, general science, mine, mill and aggregate, surveying and mapping, first aid and weather — and that is just a tiny fraction of it. It even tells you how to calculate the gallons per minute coming out of a pipe or hose by measuring the arc of the discharge.
With its 3" × 5 1/2" softcover format, it is handy to carry or store and makes an excellent gift.
