It Was a Dark Time for the Galaxy In the late 1980s, Star Wars was becoming a fading memory. The movie trilogy had concluded. The comic books and novels were winding down. The action figures had run their course. As the franchise celebrated its tenth anniversary, there was a new ride at Disneyland and ... not much else. Not until a small hobby game company released Star Wars: The Roleplaying Game and The Star Wars Sourcebook. And suddenly the galaxy began to expand.This is the story of how a group of dedicated fans and gaming professionals helped pave the way for the Star Wars Expanded Universe - as told by one of the original architects! This book explains how material created for roleplaying games helped shape the Star Wars universe - and continues to influence it to the current day.

Collingwood's theory of philosophical method applied to the problem of the philosophy of nature.

A coherent introduction for researchers in astronomy, particle physics, and cosmology on the formation and evolution of galaxies.

In this fascinating Very Short Introduction, popular science writer John Gribben tells the story of our growing understanding of galaxies, from the days before Galileo to our present-day observations of our many hundreds of millions of galactic neighbors. Not only are galaxies fascinating astronomical structures in themselves, but their study has revealed much of what we know today about the cosmos, providing a window on the Big Bang and the origins of the Universe. Gribben looks at our own "Milky Way" Galaxy in detail, from the different kinds of stars that are born within it, to the origins of its magnificent spiral structure. Perhaps most interesting, Gribben describes the many exciting discoveries have been made about our own galaxy and about those beyond: how a supermassive black hole lurks at the center of every galaxy, how enormous forces are released when galaxies collide, how distant galaxies provide a window on the early Universe, and how the formation of young galaxies shed needed light on the mysteries of Cold Dark Matter. John Gribbin is one of the best-known current popular science writers. His many books include the acclaimed The Universe: A Biography, In Search of Schrodinger's Cat, and Science: A History. He has written for many newspapers and regularly contributes to radio and television documentaries and debates, and also writes science fiction novels. He formerly worked for Nature and New Scientist and is presently a Visiting Fellow in Astronomy at the University of Sussex. 1. A Very Short Introduction 2. The Great Debate 3. Our Island 4.

NAMED ONE OF THE BEST BOOKS OF THE YEAR BY NPR • A gripping science fiction saga about three students from a school for those with extraordinary powers, from the award-winning author of The Best of All Possible Worlds “A smart science fictional fable as inventive and involving as it is finally vital.”—Tordotcom On the verge of adulthood, Rafi attends the Lyceum, a school for the psionically gifted. Rafi possesses mental abilities that might benefit people . . . or control them. Some wish to help Rafi wield his powers responsibly; others see him as a threat to be contained. Rafi’s only freedom at the Lyceum is Wallrunning: a game of speed and agility played on vast vertical surfaces riddled with variable gravity fields. Serendipity and Ntenman are also students at the Lyceum, but unlike Rafi, they come from communities where such abilities are valued. Serendipity finds the Lyceum as much a prison as a school, and she yearns for a meaningful life beyond its gates. Ntenman, with his quick tongue, quicker mind, and a willingness to bend if not break the rules, has no problem fitting in. But he too has his reasons for wanting to escape. Now the three friends are about to experience a moment of violent change as seething tensions between rival star-faring civilizations come to a head. For Serendipity, this change will challenge her ideas of community and self. For Ntenman, it will open new opportunities and new dangers. And for Rafi, given a chance to train with some of the best Wallrunners in the galaxy, it will lead to the discovery that there is more to Wallrunning than he ever suspected . . . and more to himself than he ever dreamed. Includes two bonus short stories “There is a weight and grace to [Lord’s] prose that put me in mind of pewter jewelry.”—NPR “This novel is a satisfying exercise in being off-balance, a visceral lesson in how to fall forward and catch yourself in an amazing new place.”—The Seattle Times

Provides advanced students with an introduction to modern galactic dynamics, and equips them with useful observational and theoretical tools.
