Two leading scientists discuss nature, knowledge, and faith from atheistic and Christian perspectives. What can science tell us about the meaning of life? Where are its limits, and—when we reach them—where do we turn for truth and meaning? Does faith in Jesus have anything to add? Ian Hutchinson, professor of nuclear science and engineering at MIT, is a committed Christian believer. Roald Hoffman, Nobel laureate, theoretical chemist, and professor of humane letters at Cornell, is an atheist. Join these two leading scientists in a discussion about life's hardest questions.
