    Depth rather than breadth
  

*by W***D on Reviewed in the United States on December 23, 2011*

This book reprints a manual 130 years old, as of the time if this writing, and describes practices that were already well entrenched even then. Considering how recently slide rules fell out of fashion, I find their reign, over 100 years, surprising. And, when you see this book's emphasis on carpentry and skilled trades, it's even more astonishing that slide rules appeared in so many contexts - not just the lab full of necktied nerds with pocket protectors.That emphasis on carpentry and skilled trades comes across as this book's strength and weakness. As its strength, this goes over many of the routine kinds of calculation that appear in doing conversions and proportions, in building stairs, and in handling everyday geometry. It gives many examples of chained calculations, showing how easily the result from one step feeds into the next. And, in gentle language, it addresses the mysterious decimal point - slide rules give you the leading digits of an answer easily, but it takes some mental arithmetic to keep track of how many zeroes you need and on which side of the decimal.By focusing on basic, everyday operations, the skips over the more complex scales  that appeared during the slide rule's heyday: trig, log, exponential, squaring, and more. And, because of the 1881 publication date, you can't expect illustrations as profuse and clear as in modern how-to books. Those points seem small enough, though. Given the basics, anyone who needs the more advanced features and has them available will be able to work them out for themselves.Slide rules, for better or worse, are nearly extinct in the wild, despite their versatility, ruggedness, and unpowered operation. They've lost none of their appeal, though, as cultural icons and as historical artifacts. If you can't find someone who (like me) remembers how to use one, this book will get you and your slipstick off to a great start.- wiredweird
