Since the publication of Darwin's ''Origin of Species'' in 1859, many have found science and belief in God irreconcilable. The conflict has been heightened by the subsequent dramatic advances in physics, biology and the new fields of chaos and complexity. Some scientists insist that belief in God can sit comfortably alongside scientific knowledge; for others the idea is anathema. But this is not a question confined to scientists, philosophers and intellectuals. From the author of ''Stephen Hawking: A Quest for a Theory of Everything'', this book examines the impact of scientific discoveries and the question of whether we can ever ''find'' God - or a scientific formula that will erase once and for all the notion of God.
