"...Malcolm Longair has written a very timely book, directed toward students, researchers, and lecturers; I enjoyed experiencing all three roles while reading it. It is a lucid and in-depth presentation of the subject and introduces topics at various levels of complexity.... Longair's style very effectively engages the reader in the story of this wonderful adventure of the human mind."
