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.
This book offers an engaging and comprehensive introduction to scientific theories and the evolution of science and mathematics through the centuries. It discusses the history of scientific thought and ideas and the intricate dynamic between new scientific discoveries, scientists, culture and societies. Through stories and historical accounts, the volume illustrates the human engagement and preoccupation with science and the interpretation of natural phenomena. It highlights key scientific breakthroughs from the ancient to later ages, giving us accounts of the work of ancient Greek and Indian mathematicians and astronomers, as well as of the work of modern scientists like Descartes, Newton, Planck, Mendel and many more. The author also discusses the vast advancements which have been made in the exploration of space, matter and genetics and their relevance in the advancement of the scientific tradition. He provides great insights into the process of scientific experimentation and the relationship between science and mathematics. He also shares amusing anecdotes of scientists and their interactions with the world around them. Detailed and accessible, this book will be of great interest to students and researchers of science, mathematics, the philosophy of science, science and technology studies and history. It will also be useful for general readers who are interested in the history of scientific discoveries and ideas.
This book presents in a simple style the success story of modern astrophysics — how the application of known physics to models of stars can, together with the observational data, help us understand what stars are made of, how they live and how they die. The account is non-technical but scientifically accurate. It is interspersed with anecdotes and analogies to make the subject matter readable and understandable even to a lay reader with some basic scientific background.
This book is based on lectures given by the author at a number of university with the aim of introducing Cosmology to students and teachers at the graduate level. Here, cosmology is explained within the framework of Newtoroian gravity and mechanics thereby making it readily understood to students of Physics and Mathematics at the undergraduate level.

This book describes in nontechnical language one of the success stories of modern (twentieth-century) astronomy. It presents us with the physical picture of what constitutes a star, a description of how a star evolves with time, how its shape and brightness change, how it manufactures the chemical elements deep in its interior, what makes it explode… The presentation also includes exotic objects such as supernovae, pulsars, neutron stars and white dwarfs, and of course, black holes. This revised edition brings the discussion up to date with the inclusion of astronomical events like Supernova 1987A and findings from the Hubble Space Telescope as well as other observations. The book is appropriate as supplementary material for an elementary course on astronomy and astrophysics.
Acclaimed by Nature as "excellent and uncompromising," this reader-friendly book explores exploding stars, black holes, and the Big Bang. Clear and lively, it conveys the excitement of modern cosmology. 1982 edition.
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.
This book describes the subject of electrodynamics at classical as well as quantum level, developed as an interaction at a distance. Thus it has electric charges interacting with one another directly and not through the medium of a field. In general such an interaction travels forward and backward in time symmetrically, thus apparently violating the principle of causality. It turns out, however, that in such a description the cosmological boundary conditions become very important. The theory therefore works only in a cosmology with the right boundary conditions; but when it does work it is free from the divergences that plague a quantum field theory.
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.

This book conveys the thrill of observing strange and surprising features of the universe and the satisfaction gained by understanding them through modern science. Using simple analogies and a wealth of illustrations, Professor Narlikar skilfully steers us through a cosmic journey of discovery, starting from the Earth and solar system and stepping out to the farthest reaches of the universe. Each of the seven wonders represents a range of mysterious phenomena or a class of spectacular events or remarkable cosmic objects that have challenged human curiosity and often defied explanation.
