The Story of Inventions documents several key inventions that have had an important impact on the growth of our modern industrialized world. Each chapter is more than a history of a particular invention; it is also the story of the inventors who created these new products and processes. Readers will learn how major inventions came about and how the character traits of each inventor contributed to their success. The second edition includes illustrations that help the reader grasp details regarding important inventions that have changed the way people live. The twenty-one chapters in this book have been divided into four units—power, manufacturing, communications, and transportation. Comprehension questions at the end of each chapter will help students evaluate how well they understand the text.
