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.

Gazing up at the heavens from our backyards or a nearby field, most of us see an undifferentiated mess of stars—if, that is, we can see anything at all through the glow of light pollution. Today’s casual observer knows far less about the sky than did our ancestors, who depended on the sun and the moon to tell them the time and on the stars to guide them through the seas. Nowadays, we don’t need the sky, which is good, because we’ve made it far less accessible, hiding it behind the skyscrapers and the excessive artificial light of our cities. How We See the Sky gives us back our knowledge of the sky, offering a fascinating overview of what can be seen there without the aid of a telescope. Thomas Hockey begins by scanning the horizon, explaining how the visible universe rotates through this horizon as night turns to day and season to season. Subsequent chapters explore the sun’s and moon’s respective motions through the celestial globe, as well as the appearance of solstices, eclipses, and planets, and how these are accounted for in different kinds of calendars. In every chapter, Hockey introduces the common vocabulary of today’s astronomers, uses examples past and present to explain them, and provides conceptual tools to help newcomers understand the topics he discusses. Packed with illustrations and enlivened by historical anecdotes and literary references, How We See the Sky reacquaints us with the wonders to be found in our own backyards.

Richard Feynman once quipped that "Time is what happens when nothing else does." But Julian Barbour disagrees: if nothing happened, if nothing changed, then time would stop. For time is nothing but change. It is change that we perceive occurring all around us, not time. Put simply, time does not exist. In this highly provocative volume, Barbour presents the basic evidence for a timeless universe, and shows why we still experience the world as intensely temporal. It is a book that strikes at the heart of modern physics. It casts doubt on Einstein's greatest contribution, the spacetime continuum, but also points to the solution of one of the great paradoxes of modern science, the chasm between classical and quantum physics. Indeed, Barbour argues that the holy grail of physicists--the unification of Einstein's general relativity with quantum mechanics--may well spell the end of time. Barbour writes with remarkable clarity as he ranges from the ancient philosophers Heraclitus and Parmenides, through the giants of science Galileo, Newton, and Einstein, to the work of the contemporary physicists John Wheeler, Roger Penrose, and Steven Hawking. Along the way he treats us to enticing glimpses of some of the mysteries of the universe, and presents intriguing ideas about multiple worlds, time travel, immortality, and, above all, the illusion of motion. The End of Time is a vibrantly written and revolutionary book. It turns our understanding of reality inside-out.

The Sky Diaries is the remarkable true story of guardian angels, reincarnation, and one family’s journey through multiple lifetimes. It’s a tale unlike anything you’ve heard before – a saga filled with otherworldly synchronicity, signs from the afterlife, and a child so precious her fate was written in the stars. What if life after death is only the beginning? What if we come back to one another time and time again? What if a child’s past life memories hold the key to unlock the truth about reincarnation? As you’ll see, a family’s love never ends. From one life to the next, it merely changes forms.

The threat to the sky from satellite mega-constellations, why it matters, and what we can do about it From the foreword by Brian May: "Professor Lawrence, in this timely book, tackles an issue which is about to become highly contentious around the world... This book will hopefully spark enough discussion to put the brakes on this destruction of our dark skies." From Dava Sobel, author "Longitude" and "The Glass Universe": "At the beginning of this essential book, Andy Lawrence shares dark sky memories in which even a car breakdown on a deserted road turns magical and formative when the stars appear. Let there be dark." From Dave Eicher, editor-in-chief of Astronomy Magazine: “Professor Lawrence’s book ought to be required reading for every astronomer and astronomy enthusiast who values the starry sky and what might happen to it in future times.” From Mark McCaughrean, Senior Science Adviser, European Space Agency: "As commercial developers flood low Earth orbit with satellites to exploit the demand for more movie streaming, videoconferencing, low-latency gaming, and high-speed trading, what's the real cost? ." From Pippa Goldschmidt, author of The Falling Sky and The Need for Better Regulation of Outer Space: “An important book about an important subject. Professor Andy Lawrence explains how obliteration of our view of the heavens by the next generation of communications satellites is akin to destruction of the Earth’s natural habitats.” From John A. Murray, author or editor of 45 nature books, including Wild Africa, A Republic of Rivers, and The Islands and The Sea: "Simply put, this remarkable book should be in all libraries, public or private, that aspire to be complete on the subjects of science and technology. Working together, people around the planet, inspired by this eloquent and passionate book, can put an end to the madness and folly of "artificial constellations" "
