Are we on the brink of a new Dark Age of irrationality and superstition? In this book, the writer shows how scientific thinking is necessary to safeguard our democratic institutions and our technical civilization. This book is more personal and richer in moving and revealing human stories than anything the author has previously written. With illustrations from his own childhood experience as well as engrossing tales of discovery, he shows how the method of scientific thought can cut through prejudice and hysteria to uncover the often surprising truth. He convincingly debunks "alien abduction," "channelers," faith-healer fraud, the "face" on Mars, and much else. Along the way, he refutes the arguments that science destroys spirituality or is just another arbitrary belief system, asks why scientific study is often stigmatized, discusses the dangers of the misuse of science, and provides a "baloney detection kit" for thinking through political, social, religious, and other issues. -- Jacket

"The world's leading alien hunter" -- New York Times Magazine From acclaimed Harvard astrophysicist and bestselling author of Extraterrestrial comes a mind-expanding new book explaining why becoming an interstellar species is imperative for humanity's survival and detailing a game plan for how we can settle among the stars. In the New York Times bestseller Extraterrestrial, Avi Loeb, the longest serving Chair of Harvard's Astronomy Department, presented a theory that shook the scientific community: our solar system, Loeb claimed, had likely been visited by a piece of advanced alien technology from a distant star. This provocative and persuasive argument opened millions of minds internationally to the vast possibilities of our universe and the existence of intelligent life beyond Earth. But a crucial question remained: now that we are aware of the existence of extraterrestrial life, what do we do next? How do we prepare ourselves for interaction with interstellar extraterrestrial civilization? How can our species become interstellar? Now Loeb tackles these questions in a revelatory, powerful call to arms that reimagines the idea of contact with extraterrestrial civilizations. Dismantling our science-fiction fueled visions of a human and alien life encounter, Interstellar provides a realistic and practical blueprint for how such an interaction might actually occur, resetting our cultural understanding and expectation of what it means to identify an extraterrestrial object. From awe-inspiring searches for extraterrestrial technology, to the heated debate of the existence of Unidentified Aerial Phenomena, Loeb provides a thrilling, front-row view of the monumental progress in science and technology currently preparing us for contact. He also lays out the profound implications of becoming--or not becoming--interstellar; in an urgent, eloquent appeal for more proactive engagement with the world beyond ours, he powerfully contends why we must seek out other life forms, and in the process, choose who and what we are within the universe. Combining cutting edge science, physics, and philosophy, Interstellar revolutionizes the approach to our search for extraterrestrial life and our preparation for its discovery. In this eye-opening, necessary look at our future, Avi Loeb artfully and expertly raises some of the most important questions facing us as humans, and proves, once again, that scientific curiosity is the key to our survival.

WHAT ARE THESE GRACEFUL VISITORS TO OUR SKIES? WE NOW KNOW THAT THEY BRING BOTH LIFE AND DEATH AND TEACH US ABOUT OUR ORIGINS. Comet begins with a breathtaking journey through space astride a comet. Pulitzer Prize-winning astronomer Carl Sagan, author of Cosmos and Contact, and writer Ann Druyan explore the origin, nature, and future of comets, and the exotic myths and portents attached to them. The authors show how comets have spurred some of the great discoveries in the history of science and raise intriguing questions about these brilliant visitors from the interstellar dark. Were the fates of the dinosaurs and the origins of humans tied to the wanderings of a comet? Are comets the building blocks from which worlds are formed? Lavishly illustrated with photographs and specially commissioned full-color paintings, Comet is an enthralling adventure, indispensable for anyone who has ever gazed up at the heavens and wondered why. "SIMPLY THE BEST." *The Times of London "FASCINATING, EVOCATIVE, INSPIRING." *The Washington Post "COMET HUMANIZES SCIENCE. A BEAUTIFUL, INTERESTING BOOK." *United Press International "MASTERFUL . . . SCIENCE, POETRY, AND IMAGINATION." *The Atlanta Journal & Constitution

Book by Kuhn, Thomas S.

"Max Tegmark leads us on an astonishing journey through past, present, and future, and through the physics, astronomy and mathematics that are the foundation of his work, most particularly his hypothesis that our physical reality is a mathematical structure and his theory of the ultimate multiverse. In a dazzling combination of both popular and ground-breaking science, he not only helps us grasp his often mind-boggling theories (his website gives a flavor of how they might boggle the mind), but he also shares with us some of the often surprising triumphs and disappointments that have shaped his life as a scientist. Fascinating from first to last--here is a book for the full science-reading spectrum"--

Introduces concepts drawn from astronomy, biology, and geology to explain natural phenomena and to explore profound scientific questions about astrobiology. --From publisher description.

Frontiers probes the furthest boundaries of prehistory, science, earth space and the universe. It is a collection of short, topical and intriguing essays through which Isaac Asimov, the incomparable writer of science fiction, proposes brand new answers to classic scientific conundrums.

A funny, insightful, and self-contained guide to Einstein's relativity theory and classical field theories--including electromagnetism Physicist Leonard Susskind and data engineer Art Friedman are back. This time, they introduce readers to Einstein's special relativity and Maxwell's classical field theory. Using their typical brand of real math, enlightening drawings, and humor, Susskind and Friedman walk us through the complexities of waves, forces, and particles by exploring special relativity and electromagnetism. It's a must-read for both devotees of the series and any armchair physicist who wants to improve their knowledge of physics' deepest truths.

The beginning of the 21st century is a watershed in modern science, a time that will forever change our understanding of the universe, Susskind contends. Several decades ago, he introduced the revolutionary concept of string theory to the world of physical science. In doing so, he inspired a generation of physicists who believed that the theory would uniquely predict the properties of our universe. Now, in his first book, Susskind argues that the very idea of such an "elegant theory" no longer suits our understanding of the universe, and that our narrow 20th-century view of a unique universe will have to give way to the much broader concept of a gigantic cosmic landscape--a megaverse, pregnant with new possibilities.--[Résumé de l'éditeur].

A radically new view of the nature of the universe that suggests that the cosmosas a whole is best understood not as mechanical and clockwork, but as complete and evolving, more akin to a living entity than a machine. Comparable in its acope and ambition to Roger Penrose and Stephen Hawking, and readable than either.

Advance Praise for The Accelerating Universe " The Accelerating Universe is not only an informative book about modern cosmology. It is rich storytelling and, above all, a celebration of the human mind in its quest for beauty in all things." —Alan Lightman, author of Einstein's Dreams "This is a wonderfully lucid account of the extraordinary discoveries that have made the last years a golden period for observational cosmology. But Mario Livio has not only given the reader one clear explanation after another of what astronomers are up to, he has used them to construct a provocative argument for the importance of aesthetics in the development of science and for the inseparability of science, art, and culture." —Lee Smolin, author of The Life of the Cosmos "What a pleasure to read! An exciting, simple account of the universe revealed by modern astronomy. Beautifully written, clearly presented, informed by scientific and philosophical insights." —John Bahcall, Institute for Advanced Study "A book with charm, beauty, elegance, and importance. As authoritative a journey as can be taken through modern cosmology." —Allan Sandage, Observatories of the Carnegie Institution of Washington

Does the Universe extend forever or is there an end somewhere? Does it expand and contract like an accordion with each cosmic spasm lasting millions of years? Was there a time when it exploded and will the flying fragments separated until our own fragment is virtually alone? Does it renew itself and is it eternal, unborn and undying? This is a complete scientific survey of all that is known about the Universe, presented with the clarity and precision so characteristic of the writing of Isaac Asimov. Beginning with chapters on the earth and our solar system, he guides the reader through exploration and discovery of the unimaginably distant reaches of outer space. Barely fifty years ago, their horizons of our known universe were pushed back. The Milky Way was recognized as only a drop in a huge black ocean; other galaxies were discovered; the Universe was found to be expanding - its rim many billions of light-years away. And as man daily probes further into the unknown, it is becoming clear that discoveries dwarfing all those of the past may actually be at hand.

A look up at the night sky reveals a treasury of wonders. Even to the naked eye, the Moon, stars, planets, the Milky Way and even a few star clusters and nebulae illuminate the heavens. For millennia, humans struggled to make sense of what's out there in the Universe, from all we can see to that which lies beyond the limits of even our most powerful telescopes. Beyond the Galaxy traces our journey from an ancient, Earth-centered Universe all the way to our modern, 21st century understanding of the cosmos. Touching on not only what we know but also how we know it, Ethan Siegel takes us to the very frontiers of modern astrophysics and cosmology, from the birth of our Universe to its ultimate fate, and everything in between.

A Kabbalistic Universe is about how and why Existence came into being. It sets out the general scheme of the four Worlds of Emanation, Creation, Formation and Action and heir various archangelic, angelic, demonic and organic inhabitants. Drawing upon ancient, medieval and modern material this book brings the Kabbalistic tradition up to date so that the current generation can perceive what Existence is about and how they might play a conscious part in humanity's role of aiding God to behold God in the Mirror of Existence. This is a revised edition with additional graphics. These make the Divine principles involved more comprehensible. Once the terms and metaphysics are mastered, then new perceptions are possible regarding not only the structure and dynamics of Existence but also the workings of the angelics and demonics, Nature and the process of human evolution and its purpose.
