That edition was on the cutting edge of what was then known about the origins and nature of the universe. But the intervening years have seen extraordinary advances in the technology of observing both the micro- and the macrocosmic worlds. These observations have confirmed many of Professor Hawking's theoretical predictions in the first edition of his book, including the recent discoveries of the Cosmic Background Explorer satellite (COBE), which probed back in time to within 300,000 years of the universe's beginning and revealed wrinkles in the fabric of space-time that he had projected. Eager to bring to his original text the new knowledge revealed by these observations, as well as his own recent research, Professor Hawking has prepared a new introduction to the book, written an entirely new chapter on wormholes and time travel, and updated the chapters throughout.

    Set in 1507, when the author himself was an attaché to the Duke of Urbino, the book consists of a series of fictional conversations between members of the Duke's retinue. All aspects of leadership come under discussion, but the primary focus rests upon the relationship between advisors and those whom they counsel. Ever-relevant subjects include the decision-making process, maintaining an ethical stance, and the best ways of interacting with authority figures. Frequently assigned in university courses on literature, history, and Renaissance studies, the Dover edition of this classic work will be the lowest-priced edition available.
