<br/><br/> Inventors are special people. They see everyday objects and imagine something better. They solve problems with new ideas. Their inventions can help people or destroy them, but only the greatest ideas will change the world. This book tells about many of the most interesting and important inventions, from 2,500 years ago to the present day -- p. 4 of cover.
