Flat Earth and Round Earth

Book excerpt: It can be hard to imagine a time when it was generally believed that the shape of our earth was a flat plane or disk. This book exposes the bizarre and sometimes hilarious history of science, explores pseudo-scientific theories from the past, and the scientific progress made since then through use of the scientific method. Through the scientific method, anecdotes, historic facts, and the scientific theories themselves, it tells the story of why people of a particular time period believed in such things and the discoveries that led us to learn otherwise.
