Merlin's Tour of the Universe, Revised and Updated for the Twenty-First Century

In this revised and updated edition, Neil deGrasse Tyson takes readers on an entertaining and edifying tour of the universe through his fictional character Merlin.

Merlin, a timeless visitor from Planet Omniscia in the Andromeda Galaxy, has observed firsthand many of the major scientific events of Earth's history.

He answers questions from adults and children alike, often recounting playful conversations with historical scientific figures like da Vinci, Magellan, Newton, Einstein, and Hubble.

The book is enhanced by humorous cartoons created by Stephen J. Tyson, which help clarify phenomena such as gravity, light, space, and time.
