Tom Whipple: The Battle of the Beams

My guest in this week's Book Club podcast is Tom Whipple, science editor of the Times and author of the gripping new book The Battle of the Beams: The secret science of radar that turned the tide of the Second World War. He describes the ingenious technological, psychological and espionage battles that made electromagnetic warfare a decisive – if under-appreciated – contributor to Britain's victory in the air war and, finally, in the Normandy Landings.
