This is an autobiography of this well known author with a unique perspective arising from his roles as both a theologian and a physicist. It tells the story of his journeys into both disciplines from a human angle, including the formative experiences and key relationships he experienced as a child, an undergraduate, graduate and beyond into university teaching, priesthood and writing. He describes his developing thoughts and understanding of the value and interdependence of each of the major disciplines and, by so doing, brings a human touch to the big questions that each approach raises.
