Even in their poor resolution, the images stunned scientists: the far side is an enormous mountainous expanse, not the vast lava-plains seen from Earth. Subsequent missions have confirmed this in much greater detail.How could this be, and what might it tell us about our own place in the universe? As it turns out, quite a lot.Fourteen billion years ago, the universe exploded into being, creating galaxies and stars. Planets formed out of the leftover dust and gas that coalesced into larger and larger bodies orbiting around each star. In a sort of heavenly survival of the fittest, planetary bodies smashed into each other until solar systems emerged. Curiously, instead of being relatively similar in terms of composition, the planets in our solar system, and the comets, asteroids, satellites and rings, are bewitchingly distinct. So, too, the halves of our moon.In When the Earth Had Two Moons, esteemed planetary geologist Erik Asphaug takes us on an exhilarating tour through the farthest reaches of time and our galaxy to find out why. Beautifully written and provocatively argued, When the Earth Had Two Moons is not only a mind-blowing astronomical tour but a profound inquiry into the nature of life here—and billions of miles from home.

    This book offers the opportunity to truly comprehend the workings of one of humanity's greatest minds. Acclaimed by Einstein himself, it is among the clearest, most readable expositions of relativity theory. It explains the problems Einstein faced, the experiments that led to his theories, and what his findings reveal about the forces that govern the universe. The concepts of relativity and the fourth dimension unfold with all the vivid excitement of research into the unknown, in language anyone can readily understand.

    Sci-fi makes it look so easy. Receive a distress call from Alpha Centauri? No problem: punch the warp drive and you're there in minutes. Facing a catastrophe that can't be averted? Just pop back in the timestream and stop it before it starts. But for those of us not lucky enough to live in a science-fictional universe, are these ideas merely flights of fancy—or could it really be possible to travel through time or take shortcuts between stars? Cutting-edge physics may not be able to answer those questions yet, but it does offer up some tantalizing possibilities. In Time Travel and Warp Drives, Allen Everett and Thomas A. Roman take readers on a clear, concise tour of our current understanding of the nature of time and space—and whether or not we might be able to bend them to our will. Using no math beyond high school algebra, the authors lay out an approachable explanation of Einstein's special relativity, then move through the fundamental differences between traveling forward and backward in time and the surprising theoretical connection between going back in time and traveling faster than the speed of light. They survey a variety of possible time machines and warp drives, including wormholes and warp bubbles, and, in a dizzyingly creative chapter, imagine the paradoxes that could plague a world where time travel was possible—killing your own grandfather is only one of them! Written with a light touch and an irrepressible love of the fun of sci-fi scenarios—but firmly rooted in the most up-to-date science, Time Travel and Warp Drives will be a delightful discovery for any science buff or armchair chrononaut.

    Taken literally, it implies that there are many universes “parallel” to the one we see around us. This multiplicity of universes, according to Deutsch, turns out to be the key to achieving a new worldview, one which synthesizes the theories of evolution, computation, and knowledge with quantum physics. Considered jointly, these four strands of explanation reveal a unified fabric of reality that is both objective and comprehensible, the subject of this daring, challenging book. The Fabric of Reality explains and connects many topics at the leading edge of current research and thinking, such as quantum computers (which work by effectively collaborating with their counterparts in other universes), the physics of time travel, the comprehensibility of nature and the physical limits of virtual reality, the significance of human life, and the ultimate fate of the universe. Here, for scientist and layperson alike, for philosopher, science-fiction reader, biologist, and computer expert, is a startlingly complete and rational synthesis of disciplines, and a new, optimistic message about existence.

    However, it is one of the basic principles of quantum theory, the most widely accepted explanation of the subatomic world - and one of the fascinating subjects dealt with in Equations of Eternity.

    Can you believe that physical reality is created by our observation of it? Physicists were forced to this conclusion, the quantum enigma, by what they observed in their laboratories.Trying to understand the atom, physicists built quantum mechanics and found, to their embarrassment, that their theory intimately connects consciousness with the physical world. Quantum Enigma explores what that implies and why some founders of the theory became the foremost objectors to it. Schr�dinger showed that it absurdly allowed a cat to be in a superposition simultaneously dead and alive. Einstein derided the theory's spooky interactions. With Bell's Theorem, we now know Schr�dinger's superpositions and Einstein's spooky interactions indeed exist.Authors Bruce Rosenblum and Fred Kuttner explain all of this in non-technical terms with help from some fanciful stories and bits about the theory's developers. They present the quantum mystery honestly, with an emphasis on what is and what is not speculation.Physics' encounter with consciousness is its skeleton in the closet. Because the authors open the closet and examine the skeleton, theirs is a controversial book. Quantum Enigma's description of the experimental quantum facts, and the quantum theory explaining them, is undisputed. Interpreting what it all means, however, is controversial.Every interpretation of quantum physics encounters consciousness. Rosenblum and Kuttner therefore turn to exploring consciousness itself--and encounter quantum physics. Free will and anthropic principles become crucial issues, and the connection of consciousness with the cosmos suggested by some leading quantum cosmologists is mind-blowing.Readers are brought to a boundary where the particular expertise of physicists is no longer a sure guide. They will find, instead, the facts and hints provided by quantum mechanics and the ability to speculate for themselves.

    The opening section, Ninety Years of Mapping at National Geographic, traces the founding of Geographic cartography to the present advances in technology and the practice of compiling and organizing geographic information. The atlas truly begins with three stunning new, full-spread world maps, that drape Earth's surface seamlessly with satellite imagery, then physical and natural features, and finally today's political world of countries and growing cities.World thematic topics are organized into two groups: the Physical and Natural World and Human Activities. The Physical and Natural World section includes captivating core topics such as the evolution of earth, geology and tectonics, climate and weather, oceans, world water, the bioshere, and biodiversity. Human Activities covers 11 world themes: population, migration and refugees, conflict and terrorism, cultures, economy, energy and minerals, communications, food, health and education, the environment, and ending with wildlands. All of these intriguing spreads reflect the most authoritative and recent data available and are reviewed by preeminent scholars and experts. Lined up after the world thematic focus is the continental division. All seven continents open with views from space and are then represented with separate physical and political maps. Larger scale regions of each continent are presented for higher definition and detail. Because of our primary readership, additional coverage is given to the UnitedStates and Canada. An entirely new component to the Eighth Edition is the city section. Maps and text discussing urban explosion will open this compilation of sixty new maps. Pictures, fact boxes, and text will accompany each city map to create colorful and informative portraits of our built environment. Selected cites such as, New York, Mexico City-the most densely populated city in the world, and Paris will receive more detailed scaling. Less familiar and remote areas of the world and beyond-the poles, the ocean floors, and space-are mapped with new data and findings and dramatic effects. The addition of a new spread and map devoted to Mars will provide a timely reference to the expected news coverage of NASA's Mars Exploration Rover Mission-Spirit and Opportunity. Flags and facts of every country in the world have been newly designed and consolidated into one section, listed in alphabetical order. Locater maps and cross referencing to corresponding large-scale map plates are provided for every entity. Text for each independent country summarizes physical and cultural aspects, while facts reveal the status of population, religion, area, capital, language, literacy, life expectancy, GDP, and economy. A user-friendly, 136 page, comprehensive place-name index cross-references over 130,000 geographical sites and areas. An appendix presents valuable, convenient reference to time zones, metric conversions, foreign terms, abbreviations, airline distances, and temperature and rainfall statistics from all corners of the globe. Navigating throughout the atlas is made easy with enhanced cross-referencing, pointers, labels and an end sheet that includes a visual key with corresponding platenumbers to all the maps. Every map spread in the atlas will include interactive features and access to up-to-the-minute updates and information via the electronic National Geographic Map Machine. Streams of information are available to us on myriad topics and on many fronts. At the same time, there is a need-greater than ever-to better understand our global culture. The Eighth Edition helps bridges the gap with a collection of maps and information that is as engaging as it is informative.

    This behavior is very much different from what we humans are used to dealing with in our everyday lives, so naturally this subject is quite hard to comprehend for many. We believed that the best way to introduce the subject reliably is to start at the beginning, presenting the observations, thoughts and conclusions of each of the world’s greatest physicists through their eyes, one at a time. In this way we hope that the reader may take an enjoyable journey through the strange truths of quantum theory and understand why the conclusions of these great minds are what they are. This book starts with the most general view of the world and gradually leads readers to those new, unbelievable but real facts about the very nature of our universe.

    Sutter emphasizes how amazing it is that we are part of such a huge, complex, and mysterious place. Through metaphors and uncomplicated language, Sutter breathes life into the science of astrophysics, unveiling how particles, forces, and fields interplay to create the greatest of cosmic dramas. Touched with the author's characteristic breezy, conversational style--which has made him a breakout hit on venues such as The Weather Channel, the Science Channel, and his own popular Ask a Spaceman! podcast--he conveys the fun and wonder of delving deeply into the physical processes of the natural universe. He weaves together the past and future histories of our universe with grounded descriptions of essential modern-day physics as well as speculations based on the latest research in cosmology. Topics include our place in the Milky Way galaxy; the cosmic web--a vast web-like pattern in which galaxies are arranged; the origins of our universe in the big bang; the mysteries of dark matter and dark energy; how science has dramatically changed our relationship to the cosmos; conjectures about the future of reality as we know it; and more.For anyone who has ever stared at the starry night sky and wondered how we humans on Earth fit into the big picture, this book is an essential roadmap.

    Following the hugely successful The Science Book and The Math Book comes a richly illustrated chronology of physics, containing 250 short, entertaining, and thought-provoking entries. In addition to exploring such engaging topics as dark energy, parallel universes, the Doppler effect, the God particle, and Maxwells demon, the books timeline extends back billions of years to the hypothetical Big Bang and forward trillions of years to a time of “quantum resurrection.” Like the previous titles in this series, The Physics Book helps readers gain an understanding of major concepts without getting bogged down in complex details.

    The incredible projects described here were not merely flights of fancy dreamed up by space enthusiasts, but actual missions planned by leading aeronautical engineers. Some were designed but not built; others were built but not flown; and a few were flown to failure but little reported: A giant rocket that would use atomic bombs as propulsion (never mind the fallout), military bases on the moon that could target enemies on earth with nuclear weapons, a scheme to spray-paint the lenses of Soviet spy satellites in space, the rushed Soyuz 1 spacecraft that ended with the death of its pilot, the near-disaster of the Apollo 11 moon landing, the mysterious Russian space shuttle that flew only once and was then scrapped--these are just some of the unbelievable tales that Pyle has found in once top-secret documents as well as accounts that were simply lost for many decades. These stories, complimented by many rarely-seen photos and illustrations, tell of a time when nothing was too off-the-wall to be taken seriously, and the race to the moon and the threat from the Soviet Union trumped all other considerations. Readers will be fascinated, amused, and sometimes chilled.

    Those who believe that myths are something that exist only in the far distant path are incorrect. Anyone who knows a little bit about modern river monsters knows they are the root of 20th and even 21st century cryptozoology myths. For children, reading about these amazing creatures, both ones we know exist and those that are pure fantasy, opens many doors of imagination. The sense of wonder gained helps the young ones to think more broadly about the world.

    Just the right amount of science. Common sense and rational.” -- Wayne R. The greenhouse effect is always quoted—but that is a METAPHOR. What is the fundamental physical process that drives it? And how exactly does human activity play such a powerful role with it? How did we go from worrying about global warming to climate change…to carbon dioxide (CO2) emissions? "Great book - should me mandatory reading for anyone that uses the term 'Climate Change' " - Amazon purchaser Macsugar Are there gases more powerful and influential in the greenhouse effect than CO2? Yes, by a lot! As you will learn in this book… Why aren’t we spending more time, money, and attention focusing on those? Smart people want to get to the point of a problem and solve it as quickly, inexpensively, and effortlessly as possible. They know about the Pareto Principle, and you will too after you read this book. It is also called the 80/20 rule. What happens when we apply that principle to the global climate change “consensus”? “Thank You! I always thought the numbers were small, but I never took the time to do the math.” -- Mike S. There are many books that are long, technical, and—frankly, irrelevant—on the topic of climate change. Here are the most important questions that nobody has bothered to answer in straightforward, simple and short language, until now: * What are basic facts about our planet’s atmosphere? And what do they tell us about the fundamental physics of climate change? * What are the basic physics and assumptions behind the anthropogenic global warming (AGW) hypothesis or belief? Are they valid? * What element or compound is the single greatest factor in temperature control in our atmosphere? Hint—it isn’t carbon dioxide. How does carbon dioxide compare with this other chemical? "Takes less than an hour to read... A must-read for every official policy-maker at every level... This deserves 6 stars out of 5!" -- Terry Dunleavy (Amazon reviewer) “Brilliant, what a refreshing approach.” -- Christopher K. Before we spend more time, money, and emotional energy on the presumed EFFECTS and CONSEQUENCES of global warming and climate change (things like rising temperatures, rising sea levels, etc., etc.), shouldn’t we all have a BASIC UNDERSTANDING of the FUNDAMENTAL PROCESSES AND PHYSICS of our planet’s atmosphere? If you have any questions, or doubts about that, this book is for you. “Very good. I am a geophysicist.” -- Ben B. Even better, you’ll learn (or re-learn) a very simple and indisputable fact about our atmosphere that makes the entire controversy look ridiculous. Use this information as a test (or a bet) the next time you talk with someone on the “other side” of the climate change debate. “A very useful contribution to bringing sanity and reason back to the analysis of AGW.” – Tom P. The climate change threat is consuming more of our precious time, energy, and resources. So is the debate about what to do about it. Don’t allow yourself be a part of the problem—get this book so that you can be a part of the solution! If you are convinced that AGW is the biggest threat facing our planet, this book has facts and

    joins Ford Motor Co. in 1948, he has no idea the part he'll play in automotive history. Morsey's arrival comes as Henry Ford II and other titans in the industry are about to kill the vaunted V-8 engine. He sees it as his sole mission to talk them out of it. In The Man Who Saved the V-8, he shares the never-before-told story of how his crusade saved the engine that would go on to power iconic cars like the Ford Thunderbird and Mustang. "To this day, I have no idea how a young, newly hired manager like myself...had the nerve to challenge the most powerful men inside Ford Motor Company and tell them they were wrong," Morsey says. "But that is exactly what I did." The twenty-nine-year-old executive embarks on massive market research. He works with manufacturing experts to find ways to produce the V-8 engine more efficiently. After finding success, he goes on to continue playing a central role in some of the most pivotal decisions that would ensure Ford remains one of the powerhouses in the automotive industry. The Man Who Saved the V-8 tells the story of his successes and lessons learned.

    A concise look at the impact of the advent of the telescope on the way humans view the universe and their place in it focuses on the visionaries, beginning with Galileo, who created and perfected it.
