The science/faith debate rages on. Yet many leading scientists have an active Christian faith. Here 17 scientists, all esteemed by their peers, tackle two questions: what difference their faith makes to their scientific practice; and, what difference their science makes to their understanding of their faith. Contributors include: Francis Collins, Director, Human Genome Project; Joan Centrella, Chief of the Gravitational Astrophysics Laboratory, NASA; Bob White, Professor of Geophysics, University of Cambridge; Alister McGrath, Professor of Historical Theology, University of Oxford, and molecular biologist; and, Wilson Poon, Professor of Physics, University of Edinburgh.
