Wilson Literary Science Writing Award Harvard's top astronomer lays out his controversial theory that our solar system was recently visited by advanced alien technology from a distant star. "Provocative and thrilling ... Loeb asks us to think big and to expect the unexpected."--Alan Lightman, New York Times bestselling author of Einstein's Dreams and Searching for Stars on an Island in Maine In late 2017, scientists at a Hawaiian observatory glimpsed an object soaring through our inner solar system, moving so quickly that it could only have come from another star. Avi Loeb, Harvard's top astronomer, showed it was not an asteroid; it was moving too fast along a strange orbit, and left no trail of gas or debris in its wake. There was only one conceivable explanation: the object was a piece of advanced technology created by a distant alien civilization. In Extraterrestrial, Loeb takes readers inside the thrilling story of the first interstellar visitor to be spotted in our solar system. He outlines his controversial theory and its profound implications: for science, for religion, and for the future of our species and our planet. A mind-bending journey through the furthest reaches of science, space-time, and the human imagination, Extraterrestrial challenges readers to aim for the stars--and to think critically about what's out there, no matter how strange it seems.

"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.

Although Galileo Galilei lived and died centuries ago, his story is more relevant to our lives than we might realize. Today we face enormous challenges such as climate change that are disregarded or questioned by those who fear that their implications will damage business profitability. Others posit a false dichotomy between religion and science in order to reject scientific evidence whose implications they fear. Galileo confronted this problem 400 years ago. His discoveries were based on observation and experiment. His telescopes revealed previously unknown planets, moons orbiting other planets, and other discoveries that essentially confirmed the Copernican universe that the Church had rejected as heretical because Church theologians insisted on a literal reading of the Bible. Even St. Augustine in the fifth century maintained that the Bible pertained to the realm of faith, not reason. But when Galileo argued essentially the same position before an ecclesiastical court in Rome, he was forbidden from publishing any more books. Livio's life of Galileo shows us how the great thinker made his discoveries about the heavens and also formulated fundamental laws of physics. As an astrophysicist, Livio brings insight into how Galileo reasoned his way to his conclusions, which we know today were accurate. Along with Newton, Galileo remains one of the two great figures at the dawn of the scientific revolution. He insisted on reaching the widest audience possible, publishing his work in Italian rather than Latin as had been the case until his time, when vernacular languages were rapidly replacing Latin throughout Europe. Galileo believed that every educated person should know science as well as literature. Did Galileo actually say at the end of his trial when he was forced to recant his discoveries, as legend has it, And still it moves, referring to the motion of the earth around the sun? Not likely, says Livio, but Galileo nonetheless remains an inspiration to scientists and those who value open-minded inquiry, which as Livio reminds us, remains threatened even today.

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].

Over the past twenty years, astronomers have identified hundreds of extrasolar planets--planets orbiting stars other than the sun. Recent research in this burgeoning field has made it possible to observe and measure the atmospheres of these exoplanets. This is the first textbook to describe the basic physical processes--including radiative transfer, molecular absorption, and chemical processes--common to all planetary atmospheres, as well as the transit, eclipse, and thermal phase variation observations that are unique to exoplanets. In each chapter, Sara Seager offers a conceptual introduction, examples that combine the relevant physics equations with real data, and exercises. Topics range from foundational knowledge, such as the origin of atmospheric composition and planetary spectra, to more advanced concepts, such as solutions to the radiative transfer equation, polarization, and molecular and condensate opacities. Since planets vary widely in their atmospheric properties, Seager emphasizes the major physical processes that govern all planetary atmospheres. Moving from first principles to cutting-edge research, Exoplanet Atmospheres is an ideal resource for students and researchers in astronomy and earth sciences, one that will help prepare them for the next generation of planetary science. The first textbook to describe exoplanet atmospheres Illustrates concepts using examples grounded in real data Provides a step-by-step guide to understanding the structure and emergent spectrum of a planetary atmosphere Includes exercises for students

Carl Gustav Jung (1875-1961) and Wolfgang Ernst Pauli (1900 - 1958) were two of the greatest thinkers of modern times. Jung is the founder of Analytical Psychology and is one of the best known researchers in the field of Dream Interpretation and Symbolization. Pauli was one of the pioneers of Quantum Physics. In 1945, Pauli received the Nobel Prize in Physics after being nominated by Albert Einstein for his "decisive contribution through his discovery of a new law of Nature, the exclusion principle" involving spin theory underpinning the structure of matter and the whole of chemistry. Together they collaborated on this book that was First published in 1952 in German as Naturerklarung und Psyche. C. G. Jung: Synchronizitat als ein Prinzip akausaler Zusammenhange. W. Pauli: Der Einfluss archetypischer Vorstellungen auf die Bildung naturwissenschaftlicher Theorien bei Kepler. However, our reviewer, himself an eminent professor of mathematics, concludes, "After thoroughly studying their writings for many months now, I have come to see clearly that they are both utterly mad.""

"Robert Zubrin is a true engineering genius like the heroic engineers of the past." -- Frederick Turner, American Enterprise Using nuts-and-bolts engineering and a unique grasp of human history, Robert Zubrin takes us to the not-very-distant future, when our global society will branch out into the universe. From the current-day prospect of lunar bases and Mars settlements to the outer reaches of other galaxies, Zubrin delivers the most important and forward-looking work on space and the true possibilities of human exploration since Carl Sagan's Cosmos. Sagan himself said of Zubrin's humans-to-Mars plan, " Bob Zubrin really, nearly alone, changed our thinking on this issue." With Entering Space , he takes us further, into the prospect of human expansion to the outer planets of our own solar system--and beyond.

Two world-renowned scientists present an audacious new vision of the cosmos that “steals the thunder from the Big Bang theory.” — Wall Street JournalThe Big Bang theory—widely regarded as the leading explanation for the origin of the universe—posits that space and time sprang into being about 14 billion years ago in a hot, expanding fireball of nearly infinite density. Over the last three decades the theory has been repeatedly revised to address such issues as how galaxies and stars first formed and why the expansion of the universe is speeding up today. Furthermore, an explanation has yet to be found for what caused the Big Bang in the first place.In Endless Universe , Paul J. Steinhardt and Neil Turok, both distinguished theoretical physicists, present a bold new cosmology. Steinhardt and Turok “contend that what we think of as the moment of creation was simply part of an infinite cycle of titanic collisions between our universe and a parallel world” ( Discover ). They recount the remarkable developments in astronomy, particle physics, and superstring theory that form the basis for their groundbreaking “Cyclic Universe” theory. According to this theory, the Big Bang was not the beginning of time but the bridge to a past filled with endlessly repeating cycles of evolution, each accompanied by the creation of new matter and the formation of new galaxies, stars, and planets.Endless Universe provides answers to longstanding problems with the Big Bang model, while offering a provocative new view of both the past and the future of the cosmos. It is a “theory that could solve the cosmic mystery” ( USA Today ).

"From Aristotle to Newton, Einstein and quantum mechanics, Introducing the Universe recounts the revolutions in physics and astronomy that underlie the present-day scientific picture of the Universe. It describes the scale of things, from atoms to galactic superclusters, and sketches the cosmological theories, based on Einstein's general relativity, used to describe the Universe's expansion. The book also discusses the significance of the cosmic background satellite observations, and explains why current theories have nothing reliable to say about whether the Universe had a 'beginning'."--BOOK JACKET.
