A leading astronomer takes readers behind the scenes of the thrilling science of stellar archaeology and explains how sections of the night sky are "excavated" in the hunt for extremely rare, 13-billion-year-old relic stars and how this quest reveals tantalizing new details about the origins and evolution of the cosmos.
In this meditation on religion and science, Lightman explores the tension between our yearning for permanence and certainty, and the modern scientific discoveries that demonstrate the impermanent and uncertain nature of the world. As a physicist, he has always held a scientific view of the world. But one summer evening, while looking at the stars from a small boat at sea he was overcome by the sensation that he was merging with a grand and eternal unity, a hint of something absolute and immaterial. This is his exploration of these seemingly contradictory impulses, and the journey along the different paths of religion and science that become part of his quest. -- adapted from publisher info.
The formation of the first stars (Pop III stars) and galaxies is one of the great outstanding challenges in modern astrophysics and cosmology. The first stars are likely key drivers for early cosmic evolution and will be at the center of attention over the next decade. The best available space and ground-based telescopes like the Hubble Space Telescope probe the Universe to high redshifts and provide us with tantalizing hints; but they cannot yet directly detect the first generation of stars and the formation of the first galaxies. This is left as key science for future telecopes like the James Webb Space Telescope. This book is based in part on classroom tested lectures related to Pop III stars, but also draws from the author's review articles of the main physical principles involved. The book will thus combine pedagogical introductory chapters with more advanced ones to survey the cutting-edge advances from the frontier of research. It covers the theory of first star formation, the relation between first stars and dark matter, their impact on cosmology, their observational signatures, the transition to normal star formation as well as the assembly of the first galaxies. It will prepare students for interpreting observational findings and their cosmological implications.
The book attempts to present a new perspective to its readers for looking self and surrounding world. It tries to tell that we humans, all living beings and all non living things, moon, planets, stars, galaxies are made of the same matter particles. How everything is cosmically connected? How all matter, all space, all energy has been formed during the cosmic evolution? What are different ways to decipher such understanding? What are the scientific principles, laws and theories which help in explaining and understanding them? What are the tools and techniques which enable us to look, to experience and to test them? How vast is the universe and how small and insignificant we are? In short, the book provides a cosmic perspective for self realization to mankind. The Bhagavad Gita mentions one of the paths for salvation as Gyan Yoga (the path of knowledge for self realization). This book is a step forward in that direction. While giving brief account of cosmos, the book tries to soften human ego and expects its readers to keep our earthly differences aside and realize our cosmic connection.
Astrobiology refers to the study of the origin, evolution, distribution, and future of life in the universe. This encompasses extraterrestrial life and life on Earth. Astrobiology is an interdisciplinary field that is gaining a rapidly growing interest among both the general public and the astronomical research community. This e-book explains the detection and evolution of exoplanets and discusses the question of habitability on such objects. Chapters in this text include cited references enabling the reader to acquire more information on specific aspects of astrobiology. It is also a suitable textbook for introductory taught courses in universities and colleges on the subject.
Written for the educated non-scientist and scientist alike, it spans a variety of scientific disciplines, from observational astronomy to particle physics. Concepts that the reader will encounter along the way are at the cutting edge of scientific research. However the themes are explained in such a way that no prior understanding of science beyond a high school education is necessary.
Barrie Jones addresses the question "are we alone?", which is one of the most frequently asked questions by scientists and non-scientists alike. In The Search for Life Continued, this question is addressed scientifically, and the author is not afraid to include speculation. Indeed, the author believes beyond reasonable doubt that we are not alone and this belief is based firmly on frontier science of the most imaginative kind. The author concentrates on planetary systems beyond our own but starts with life on Earth, which is the only life we know to exist, and which provides guidance on how best to search for life elsewhere. Planets are the most likely abode of life and so we start the quest with the search for planets beyond the Solar System – exoplanets. The methods of searching are outlined and the nature of hundreds of exoplanetary systems so far discovered described. In the near future we expect to discover habitable Earth-like planets. But are they actually inhabited? How could we tell? All will be revealed. This full color book is written for everybody who wants to stay in close contact with the latest on possible life on other planets.
Critical acclaim for John Gribbin "The master of popular science." —Sunday Times (London) "Gribbin explains things very well indeed, and there's not an equation in sight." —David Goodstein, The New York Times Book Review (on Almost Everyone's Guide to Science) "Gribbin breathes life into the core ideas of complexity science, and argues convincingly that the basic laws, even in biology, will ultimately turn out to be simple." —Nature magazine (on Deep Simplicity) "Gribbin takes us through the basics [of chaos theory] with his customary talent for accessibility and clarity. [His] arguments are driven not by impersonal equations but by a sense of wonder at the presence in the universe and in nature of simple, self-organizing harmonies underpinning all structures, whether they are stars or flowers." —Sunday Times (London) (on Deep Simplicity) "In the true quantum realm, Gribbin remains the premier expositor of the latest developments." —Booklist (on Schrödinger's Kittens and the Search for Reality)
