Our world is filled with technological marvels. Computers, automobiles, telephones, radio, television....these are just a few of the contributions made by the world's engineers. The National Academy of Engineering celebrates the 20th century's greatest achievements in engineering with this lavishly illustrated, full-color book. At the very top of the list is electrification. More than half of the "Top 20" would not have been possible without it. Electrification changed America's economic development and gave the rural population the same opportunities and amenities as people in the cities. If anything shines as an example of how engineering has changed the world, it is clearly electric power. More than a simple tally of engineering achievements,"A Century of Innovation" is proof positive that the innovations made possible by the talented engineers of the world have truly transformed the way people live.
