This fascinating book offers readers an in-depth look at these unique artifacts, which are not only clever and amusing (where else could you dial-in ingredients to concoct creamed oysters and celery?) but remain arguably relevant as a model for modern interactive design. From circular mathematical slide rules to Captain Marvel phonetic decoders; from nuclear bomb blast calculators to gestational breeding planners; and from astronomical planispheres to presidential trivia plotters, Reinventing the Wheel demonstrates the astonishing range and remarkable utility of these ingenious interactive tools.
