Seen | Unseen is a deep, richly illustrated, and erudite analysis of the interconnections between science and the visual arts. Martin Kemp explores the responses of artists, scientists, and their instruments, to the world - ranging from early representations of perspective, to pinhole cameras, particle accelerators and the Hubble telescope. From Leonardo, Durer, and the inventors of photography to contemporary sculptors, and from Galileo and Darwin to Stephen J. Gould, Kemp considers the way in which scientists and artists have perceived the world and responded to its patterns, and sees common 'structural intuitions' reflected in their work.
