Book Description
The story of physicists' quest to answer a mind-boggling question: How can we travel through time? Since H. G. Wells' 1895 classic The Time Machine, readers of science fiction have puzzled over the paradoxes of time travel. What would happen if a time traveler tried to change history? Would some force or law of nature prevent him? Or would his action produce a "new" history, branching away from the original?In the last decade of the twentieth century a group of theoretical physicists at the California Institute of Technology undertook a serious investigation of the possibility of pastward time travel, inspiring a serious and sustained study that engaged more than thirty physicists working at universities and institutes around the world.Many of the figures involved are familiar: Einstein, Stephen Hawking and Kip Thorne; others are names known mostly to physicists. These are the new time travelers, and this is the story of their work--a profoundly human endeavor marked by advances, retreats, and no small share of surprises. It is a fantastic journey to the frontiers of physics. Some images in the ebook are not displayed owing to permissions issues.

Book Description
The bubbles were swirling all around me, massaging my body. As I luxuriated in this fantastic bath, I gasped realizing that those bubbles carried with them miniature galaxies bringing the entire Cosmos into my bathtub... Alfie is back. And so are George and other characters from the author’s previous book Einstein’s Enigma or Black Holes in My Bubble Bath. While the present book, Universe Unveiled - The Cosmos in My Bubble Bath, is completely independent, its storyline can be considered a sequel to the previous one. The scientific content spanning ancient world models to the most recent mysteries of cosmology is presented in an entirely nontechnical and descriptive style through the discussions between Alfie, the enlightened learner, and George, professor of astrophysics. Fantasies, based on these discussions that cover the scientific facts, are created by the magical bubble baths taken by Alfie. Universe Unveiled blends accurate science with philosophy, drama, humour, and fantasy to create an exciting cosmic journey that reads like a novel and educates as it entertains. “Spurred by a series of mind-bending discoveries, Man’s millennial love affair with the stars has now reached fever pitch. No one writing today is better positioned to evoke the romance and beauty of these cosmic discoveries than Vishveshwara. A leading expert in Einstein’s relativity theory, he brings a lyrical voice and a poetic sensibility to this joyful task. Universe Unveiled, a unique literary creation, transports readers into believing they can actually hear the music of the spheres.” Professor Robert Fuller, Former President, Oberlin College (USA) Author of Somebodies and Nobodies: Overcoming the Abuse of Rank

Book Description
to the Second Edition The development of astronomy in the last ten years has been nothing short of explosive. This second edition of The New Cosmos, considerably revised and enlarged, tries to share this development with its readers. Let us mention a few key words: from mo on landings, planetary probes, aild continental drift through pulsars, X-ray and y-ray sources, interstellar molecules, quasars, and the structure and evolution of stars and stellar systems right up to cosmological models. As before, the most important task of this book is to give a not too difficult introduction to present-day astronomy and astrophysics, both to the student of astronomy and to the specialist from a neighboring discipline. We therefore draw to the attention of the reader, as an essential part of our description, the numerous illustrations-many of them new-and their detailed captions. As far as possible we link a description of important observations with basic features of the theory. On the other hand, when it comes to detail we often content ourselves with abrief description, leaving the detailed explanation to the specialist literature. The transition to the specialist literature should be eased by the Bibliography at the end of the book. Important new investigations are noted in the text by their year, not so much for historical reasons as to enable the original work to be found in the Astronomy and Astrophysics Abstracts (1969 on).

Book Description
This book provides a comprehensive overview of the history of ideas about the sun and the stars, from antiquity to modern times. Two theoretical astrophysicists who have been active in the field since the early 1960s tell the story in fluent prose. About half of the book covers most of the theoretical research done from 1940 to the close of the twentieth century, a large body of work that has to date been little explored by historians. The first chapter, which outlines the period from about 3000 B.C. to 1700 A.D., shows that at every stage in history human beings have had a particular understanding of the sun and stars, and that this has continually evolved over the centuries. Next the authors systematically address the immense mass of observations astronomy accumulated from the early seventeenth century to the early twentieth. The remaining four chapters examine the history of the field from the physicists perspective, the emphasis being on theoretical work from the mid-1840s to the late 1990s--from thermodynamics to quantum mechanics, from nuclear physics and magnetohydrodynamics to the remarkable advances through to the late 1960s, and finally, to more recent theoretical work. Intended mainly for students and teachers of astronomy, this book will also be a useful reference for practicing astronomers and scientifically curious general readers.

Book Description
We now live in the time of the Gaian hierophant. This is the one who reveals and shows us how to relate to the sacred aspects of Gaia, our planet. Who is this hierophant? Each of us, when we join the campaign with Gaia against the desecration of our natural environment. But first we have to discover what the Earth really is. The Earth's thousands of sacred sites hold a secret: they are functional parts of the planet's geomantic body, consciousness nodes in the Earth's subtle body. Each veils a Light temple, each once known widely and remembered in myth, and Welcome to Your Designer Planet! documents 165 different kinds. The Earth is not an accident of the cosmos, but was designed specifically for humans as an extended Mystery temple primed to support and enhance our greater awareness. And the designers intended that humans help maintain it. Want to help the ecosystem and modulate global warming and climate change? Plug yourself into the Earth's Light grid through your nearest sacred site and start helping. Earth Mysteries researcher Richard Leviton presents a working model of the Earth's geomantic reality based on 24 years of research. The world's myths are the doorway into this fantastic domain of the Earth's visionary geography, showing us where to go and what to do and even what kinds of spiritual beings to expect to see. The future of the Earth is in our hands. Here are some pages from its design manual showing us how to fine-tune our wonderful host planet.

Book Description
An award-winning neurologist on the Stone-Age roots of our screen addictions, and what to do about them. The human brain hasn’t changed much since the Stone Age, let alone in the mere thirty years of the Screen Age. That’s why, according to neurologist Richard Cytowic—who, Oliver Sacks observed, “changed the way we think of the human brain”—our brains are so poorly equipped to resist the incursions of Big Tech: They are programmed for the wildly different needs of a prehistoric world. In Your Stone Age Brain in the Screen Age, Cytowic explains exactly how this programming works—from the brain’s point of view. What he reveals in this book shows why we are easily addicted to screen devices; why young, developing brains are particularly vulnerable; why we need silence; and what we can do to push back. In the engaging storytelling style of his popular TED Talk, Cytowic draws an easily comprehensible picture of the Stone Age brain’s workings—the function of neurotransmitters like dopamine in basic instincts for survival such as desire and reward; the role of comparison in emotion, and emotion in competition; and, most significantly, the orienting reflex, one of the unconscious circuits that automatically focus, shift, and sustain attention. Given this picture, the nature of our susceptibility to digital devices becomes clear, along with the possibility of how to break their spell. Full of practical actions that we can start taking right away, Your Stone Age Brain in the Screen Age offers compelling evidence that we can change the way we use technology, resist its addictive power over us, and take back the control we have lost.
