Pulsars are rapidly spinning neutron stars, the collapsed cores of once massive stars that ended their lives as supernova explosions. In this book, Geoff McNamara explores the history, subsequent discovery and contemporary research into pulsar astronomy. The story of pulsars is brought right up to date with the announcement in 2006 of a new breed of pulsar, Rotating Radio Transients (RRATs), which emit short bursts of radio signals separated by long pauses. These may outnumber conventional radio pulsars by a ratio of four to one. Geoff McNamara ends by pointing out that, despite the enormous success of pulsar research in the second half of the twentieth century, the real discoveries are yet to be made including, perhaps, the detection of the hypothetical pulsar black hole binary system by the proposed Square Kilometre Array - the largest single radio telescope in the world.

The investigation of language, of how (and what and why) signifiers signify, is prominent in modern critical work, but the questions being asked are by no means new. In Mervelous Signals, Eugene Vance asserts that "there is scarcely a term, practice, or concept in contemporary theory that does not have some rich antecedent in medieval thought." He goes on to illustrate the complexity and depth of medieval speculations about language and literature. Vance's study of the link between the poetics and semiotics of the Middle Ages takes both a critical and a historical view as he brings today's insights to bear on the contemporary perspectives of such works as St. Augustine's Confessions, the Chanson de Roland, Chrätien's Yvain, Aucassin and Nicolette, Spenser's The Faerie Queen, and certain aspects of the works of Dante and Chaucer and of French medieval theater.
