The Evolution Of Useful Things

Only Henry Petroski, author of The Pencil, could make one never pick up a paper clip again without being overcome with feelings of awe and reverence. In his new book the author examines a host of techno-trivia questions -- how the fork got its tines, why Scotch tape is called that, how the paper clip evolved, how the Post-it note came to be, how the zipper was named, why aluminum cans have hollow bottoms -- and provides us with answers that both astonish and challenge the imagination.In addition to an extended discussion of knives, forks, spoons, and other common devices, the author explains how the interplay of social and technical factors affects the development and use of such things as plastic bags, fast-food packaging, push-button telephones, and other modern conveniences.
