Melvyn Bragg and guests discuss whether the mass of scientific understanding and knowledge we have accumulated has destroyed our sense of poetic wonder at the world. Has our sense of awe at how the world works obscured our desire to know why it works the way it does? With Richard Dawkins evolutionary biologist, reader in Zoology and Fellow of New College, Oxford, Charles Simonyi Chair of Public Understanding of Science, Oxford University and author of Unweaving The Rainbow: Science, Delusion and The Appetite For Wonder; Ian McEwan, novelist, and author of the Booker prize winning novel Amsterdam.
