My curiosity was piqued when quite a few customers entered Ada’s, headed straight back to the alcove, and picked up a little black book, which they then purchased. Hmm…
Fascinating book, this Pocket Ref. Info, tables, and pics on this, that, and just about everything else. The chapters range alphabetically from Air & Gases to Welding; the index from ‘abrasive and sandpaper’ to ‘wounds, abdominal.’
Hand signals for crane & hoist, types of circular power handsaw blades, “ten” radio codes, and the semaphore alphabet — I gaped in awe as I paged through the book. A small non-random sampling of tables: Wire size vs. voltage drop; batteries – sizes & capacities; tire size vs. load rating, nails (number length, shaft diameter gauge, diameter of head, number per pound); stadia; earthquake scales (Richter, Moment,& Mercalli); capacities of hydraulic rams in tons; friction loss in various pipes; and sixty pages of conversion tables. A couple of my favorites are the chili pepper hotness scale and the consanguinity table (e.g., Frank and Ann are first cousins 2x removed. Huh?).
Proofreaders marks, world electric connectors, North American and world wide area codes, credit card company phone numbers, knots & bends, cloud types, formulas for electricity and plane & solid figures, degrees & trig functions – the range is wide, indeed.
There’s something for everyone. For the mathematically challenged there are tables that will tell you how much tip to leave, and how long it’ll take you to drive from here to there given that you drive not more than 250 mph. For those of you who have difficulty remembering birthdays and anniversaries, you can fill in the table on page 4. Then all you have to remember is where you left your little black book.
Seven hundred ninety-eight pages of information. And, the Pocket Ref (1.325 hands x .775 hands x .25 hands; I leave the conversion to you. See p. 700.) really fits in a pocket, although you may need a second pocket for a magnifying glass.
P.S. While I was writing this review, a fellow came in and bought two Pocket Refs, one for himself and one for his dad.
