Loud voices from both the religious and scientific communities are proclaiming that there is no conflict between science and religion-indeed, that they have much to gain from each other. I will show that this claim is flatly wrong. Religion and science are in deep conflict, and are in fact incompatible ways of viewing the world and understanding what is true in our universe. I explain this incompatibility, show the various ways that people try (and fail) to accommodate science and faith, demonstrate the tactics used by theologians to harmonize scientific findings with religious dogma, and explore the attacks on science that invariably accompany claims that science and religion are best friends.
