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 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.

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.
Gravity is the most enigmatic of all known basic forces in nature. Yet it controls everything from the motion of ocean tides to the expansion of the entire Universe. Many books use technical jargon and high-powered maths to explain what gravity is all about. In The Lighter Side of Gravity, the presentation is beautifully clear and completely non-technical. Familiar analogies, interesting anecdotes and numerous illustrations are used throughout to get across subtle effects and difficult points. The coverage is, however, comprehensive and makes no compromise with accuracy. This second edition has been brought completely up to date and expanded to include the discovery of gigantic gravitational lenses in space, the findings of the COBE satellite, the detection of MACHOS, the investigations of the very early Universe and other new ideas in cosmology. In short, this lucid and stimulating book presents 'the lighter side' of the intriguing phenomena of 'gravity' to the student and general reader.
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.
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.
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 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.

Particular emphasis is placed on radio, X- and gamma-ray observations--not covered in depth in any previous book. All those entering into this exciting and dynamic area of astronomy research will find this book an ideal introduction.
The fascinating frontier of modern cosmological research lies in the study of the very early history of the universe. This book captures the excitement of scientific investigation concerning the origins of the universe and the nature of physical laws. It describes the current search for answers to persistent, fundamental questions. Did the universe have a beginning? Is it dominated by matter rather than antimatter? Why, how, and when did galaxies form? What is the nature of matter that cannot be seen but is believed to exist? Can cosmology supply clues to the riddle of unification of all laws of physics? Combining a description of the latest discoveries with a review of basic physical laws, this remarkable work will interest many general readers as well as students and researchers in astronomy and physics.
