Why do so many Americans reject the modern theory of evolution? Seeking answers, mathematician Jason Rosenhouse became a regular attendee at creationist conferences and other gatherings. After ten years of attending events like the giant Creation Mega-Conference in Lynchburg, Virginia, and visiting sites like the Creation Museum in Petersburg, Kentucky, and after hundreds of mostly friendly conversations with creationists of varying stripes, he has emerged with a story to tell, a story that goes well beyond the usual stereotypes of Bible-thumping fanatics railing against coldly rational scientists. Through anecdotes, personal reflections, and scientific and philosophical discussion, Rosenhouse presents a more down-to-earth picture of modern creationism and the people who espouse it. He also tells the story of his own nonbeliever's attempt to understand a major aspect of American religion. Forced to wrestle with his views about religion and science, Rosenhouse found himself drawn into a new world of ideas previously unknown to him, arriving at a sharper understanding of the reality of science versus religion disputes, and how these debates look to those beyond the ivory tower.
