Flights of Fancy - Defying Gravity by Design and Evolution

Who has not dreamed, like Leonardo da Vinci, of breaking free of the tyranny of gravity and soaring through the third dimension? In his latest book, the beautifully illustrated Flights of Fancy, Richard Dawkins explores, one by one, the methods of getting off the ground and staying aloft which the laws of nature allow. They have been exploited successively by insects, pterosaurs, birds, bats and – eventually – humans. Chaired by Dr Richard Shepherd.
