This collection of science fiction writings by Jayant V. Narlikar offers readers a unique glimpse into the world-famous Indian astrophysicist’s vivid and highly imaginative concepts and stories. The fictional material comprises a witty short story ("The rare idol of Ganesha") that cleverly explores the possible consequences of a mirror-symmetric individual in the context of cricket test match performances, as well as the fast-paced, gripping science fiction thriller "The return of Vaman": when an alien container is unearthed by a crew of scientists, the enormous potential technological applications of its contents bring various criminal elements on the scene – but when the real danger becomes apparent it is almost too late to save humanity. Last but not least, the book provides readers with extensive insights into the genesis and scientific background of the fictional material presented in this volume, along with an autobiographical account of the author’s life-long interest in science fiction and his contributions to the genre. About the author: Jayant V. Narlikar is internationally known for his work in cosmology, in particular for championing models alternative to the standard big-bang theory. He was president of the cosmology commission of the International Astronomical Union from 1994 to 1997. He has received several national and international awards and honorary doctorates - he is a Bhatnagar awardee, as well as recipient of the M.P. Birla award, the Prix Janssen of the French Astronomical Society and an Associate of the Royal Astronomical Society of London. He is Fellow of the three Indian national science academies as well as of the Third World Academy of Sciences. Well beyond his scientific research, Prof. Narlikar is widely known as a science communicator through his books, articles and radio/TV programs and he was honored by the UNESCO in 1996 with the Kalinga Award. He made his debut in science fiction writing in 1974, by winning the top prize in the story writing competition organized by the Marathi Vidnyan Parishad, a non-governmental organization engaged in science popularization.

India has a rich history of scientific accomplishments. In the fifth century, nearly one millennium before Copernicus, the Indian astronomer and mathematician Aryabhata theorized that the earth spins on its axis. Likewise, in the twentieth century physicist Meghnad Saha’s ionization equation opened the door to stellar astrophysics. But India’s scientific achievements have occurred as flashes of brilliance rather than as a clear trajectory of progress. So how did India, with its historic university system and excellent observatories, lose its scientific edge? Cosmologist, founder director of the Inter-University Centre for Astronomy and Astrophysics, and science fiction author Jayant V. Narlikar tracks the highs and lows of Indian science across the millennia, distinguishing fact from fiction. Through a lively narrative of breakthroughs and failures, he explores the glories of India’s scientific advances and questions the more fanciful so-called discoveries. His essays are invigorated by his excitement for new findings, and he argues passionately for preserving the true scientific temperament instead of granting legitimacy to such pseudosciences as astrology. Above all, Narlikar raises issues that both the layperson and the scientist need to consider as India seeks to lead the world in information technology and biotechnology.

From the drop of an apple to the stately dance of the galaxies, gravity is omnipresent in the Cosmos. Even with its high profile, gravity is the most enigmatic of all the known basic forces in nature. The Lighter Side of Gravity presents a beautifully clear and completely nontechnical introduction to the phenomenon of this force in all its manifestations. Astrophysicist Jayant Narlikar begins with an historical background to the discovery of the law of gravitation by Isaac Newton in the seventeenth century. Using familiar analogies, interesting anecdotes, and numerous illustrations to get across subtle effects and difficult points to readers, he goes on to describe the general theory of relativity and some of its strange and unfamiliar ideas such as curved spacetime, the bending of light, and black holes. Since first publication in 1982 (W.H. Freeman), Dr. Narlikar has brought his book completely up to date and expanded it to include the discovery of gigantic gravitational lenses in space, the findings of the Cosmic Background Explorer (COBE) satellite, the detection of dark matter in galaxies, the investigation of the very early Universe, and other new ideas in cosmology. This lucid and stimulating book presents a clear approach to the intriguing phenomenon of gravity for everyone who has ever felt caught in its grip. Jayant Narlikar is the winner of many astronomical prizes and the author of Introduction to Cosmology (Cambridge University Press, 1993).

General relativity is now an essential part of undergraduate and graduate courses in physics, astrophysics and applied mathematics. This simple, user-friendly introduction to relativity is ideal for a first course in the subject. Beginning with a comprehensive but simple review of special relativity, the book creates a framework from which to launch the ideas of general relativity. After describing the basic theory, it moves on to describe important applications to astrophysics, black hole physics, and cosmology. Several worked examples, and numerous figures and images, help students appreciate the underlying concepts. There are also 180 exercises which test and develop students' understanding of the subject. The textbook presents all the necessary information and discussion for an elementary approach to relativity. Password-protected solutions to the exercises are available to instructors at www.cambridge.org/9780521735612.

For several decades since its inception, Einstein's general theory of relativity stood somewhat aloof from the rest of physics. Paradoxically, the attributes which normally boost a physical theory - namely, its perfection as a theoreti cal framework and the extraordinary intellectual achievement underlying i- prevented the general theory from being assimilated in the mainstream of physics. It was as if theoreticians hesitated to tamper with something that is manifestly so beautiful. Happily, two developments in the 1970s have narrowed the gap. In 1974 Stephen Hawking arrived at the remarkable result that black holes radiate after all. And in the second half of the decade, particle physicists discovered that the only scenario for applying their grand unified theories was offered by the very early phase in the history of the Big Bang universe. In both cases, it was necessary to discuss the ideas of quantum field theory in the background of curved spacetime that is basic to general relativity. This is, however, only half the total story. If gravity is to be brought into the general fold of theoretical physics we have to know how to quantize it. To date this has proved a formidable task although most physicists would agree that, as in the case of grand unified theories, quantum gravity will have applications to cosmology, in the very early stages of the Big Bang universe. In fact, the present picture of the Big Bang universe necessarily forces us to think of quantum cosmology.

“Utterly irresistible…The Gold Eaters is truly the gold standard to which all fiction — historical and otherwise — should aspire.” — Buzzfeed A sweeping, epic historical novel of exploration and invasion, of conquest and resistance, and of an enduring love that must overcome the destruction of one empire by another. Kidnapped at sea by conquistadors seeking the golden land of Peru, a young Inca boy named Waman is the everyman thrown into extraordinary circumstances. Forced to become Francisco Pizarro's translator, he finds himself caught up in one of history's great clashes of civilzations, the Spanish invasion of the Incan Empire of the 1530s. To survive, he must not only learn political gamesmanship but also discover who he truly is, and in what country and culture he belongs. Only then can he be reunited with the love of his life and begin the search for his shattered family, journeying through a land and a time vividly depicted here. Based closely on real historical events, The Gold Eaters draws on Ronald Wright’s imaginative skill as a novelist and his deep knowledge of South America to bring alive an epic struggle that laid the foundations of the modern world. From the Hardcover edition.

The first book of bestselling author Orson Scott Card's Women of Genesis series—a unique re-imagining of the biblical tale Sarai was a child of ten years, wise for her age but not yet a woman, when she first met Abram. He appeared before her in her father's house, filthy from the desert, tired and thirsty. But as the dirt of travel was washed from his body, the sight of him filled her heart. And when Abram promises Sarai to return in ten years to take her for his wife, her fate was sealed. Abram kept his promise, and Sarai kept hers. They were wed, and so joined the royal house of Ur with the high priesthood of the Hebrews. So began a lifetime of great joy together, and greater peril: and with the blessing of their God, a great nation would be built around the core of their love. Bestselling author Orson Scott Card uses his fertile imagination, and uncanny insight into human nature, to tell the story of a unique woman—one who is beautiful, tough, smart, and resourceful in an era when women had little power, and are scarce in the historical record. Sarah, child of the desert, wife of Abraham, takes on vivid reality as a woman desirable to kings, a devoted wife, and a faithful follower of the God of Abraham, chosen to experience an incomparable miracle.
