The castaway on Desert Island Discs this week is Professor Lewis Wolpert. As Chairman of the Committee on the Public Understanding of Science, he is a passionate advocate of the value of science and the increasing need for the recognition and promotion of its importance. He'll be talking to Sue Lawley about his early life in South Africa, his recent struggle with clinical depression and his passion for the views of the 18th-century philosopher David Hume - particularly on the existence of God.
