Overview

This book describes twelve inventions that transformed the United States from a rural and small-town community to an industrial country of unprecedented power. These inventions demonstrate that no one person is ever responsible for technological advances and that the culture produces a number of people who work together to create each new invention.

Themes

The book also shows the influences of technology on society and examines the beliefs and attitudes of those who partake in technological advances. The book is both a sociological analysis and a history of technology in the United States in the past two hundred years.
