PZ Myers is a biologist and associate professor at the University of Minnesota, Morris and the author of Pharyngula, the most heavily-trafficked science blog online. In this conversation with D.J. Grothe, P.Z. Myers explains the purpose and impact of his blog, and whether his priority is to advance science education or atheism. He talks about what he sees as his roles in the scientific community and the atheist movement, and how related these roles are. He explores the relationship between science and atheism, and argues that the more a public learns science, the likelier it is that they will become atheistic. And he talks about where a science educator's atheism fits in the classroom. He also addresses the position of leading scientific organizations such as the American Association for the Advancement of Science and the National Academies of Science regarding evolution being compatible with religious belief, and their use of religious scientists as spokespeople, and he assesses their motivations and strategies to advance science to a largely religious American public.
