Read The Evolution of Useful Things: How Everyday Artifacts-From Forks and Pins to Paper Clips and Zippers-Came to Be as They Are. Storyline:

How did the table fork acquire a fourth tine?  What advantage does the Phillips-head screw have over its single-grooved predecessor? Why does the paper clip look the way it does? What makes Scotch tape Scotch?In this delightful book Henry, Petroski takes a microscopic look at artifacts that most of us count on but rarely contemplate, including such icons of the everyday as pins, Post-its, and fast-food "clamshell" containers.  At the same time, he offers a convincing new theory of technological innovation as a response to the perceived failures of existing products—suggesting that irritation, and not necessity, is the mother of invention.From the Trade Paperback edition.Amazon.com ReviewThis surprising book may appear to be about the simple things of life--forks, paper clips, zippers--but in fact it is a far-flung historical adventure on the evolution of common culture. To trace the fork's history, Duke University professor of civil engineering Henry Petroski travels from prehistoric times to Texas barbecue to Cardinal Richelieu to England's Industrial Revolution to the American Civil War--and beyond. Each item described offers a cultural history lesson, plus there's plenty of engineering detail for those so inclined. From Library JournalFor armchair inventors or those who are curious about the way things work, this book offers hours of delight. Petroski (engineering, Duke Univ.) provides an intricate look, in lay reader's terms, at the technology and basic rationale behind a number of items we often take for granted. The list is comprehensive: kitchen utensils, zippers, tools, paper clips, fast-food packaging, and more. The text is far from a recital of mere facts. Petroski's anecdotes and stories about individual designers and inventors are told with warm regard. Petroski also provides illuminating thoughts on the theoretical, historical, and cultural frameworks that influenced these creations. Although this book will appeal to a somewhat specialized audience, many general readers will find it fascinating and educational. For circulating libraries.- Carol J.
