The Milky Way alone encompasses 30 trillion potential home planets. Scientists Trefil and Summers bring readers on a marvelous experimental voyage through the possibilities of life--unlike anything we have experienced so far--that could exist on planets outside our own solar system.Life could be out there in many forms: on frozen worlds, living in liquid oceans beneath ice and communicating (and even battling) with bubbles; on super-dense planets, where they would have evolved body types capable of dealing with extreme gravity; on tidally locked planets with one side turned eternally toward a star; and even on "rogue worlds," which have no star at all. Yet this is no fictional flight of fancy: the authors take what we know about exoplanets and life on our own world and use that data to hypothesize about how, where, and which sorts of life might develop. Imagined Life is a must-have for anyone wanting to learn how the realities of our universe may turn out to be far stranger than fiction.

    Spanning early celestial navigation to satellite-enabled warfare, Accessory to War is a richly researched and provocative examination of the intersection of science, technology, industry, and power that will introduce Tyson’s millions of fans to yet another dimension of how the universe has shaped our lives and our world.

    Relativity and quantum physics touch the very basis of physical reality, altering our commonsense notions of space and time, cause and effect. Both have reputations for complexity. But the basic ideas behind relativity and quantum physics are, in fact, simple and comprehensible by anyone. As Professor Wolfson points out, the essence of relativity can be summed up in a single sentence: The laws of physics are the same for all observers in uniform motion. The same goes for quantum theory, which is based on the principle that the "stuff " of the universe-matter and energy-is not infinitely divisible but comes in discrete chunks called "quanta." Profound ... Beautiful ... Relevant Why should you care about these landmark theories? Because relativity and quantum physics are not only profound and beautiful ideas in their own right, they are also the gateway to understanding many of the latest science stories in the media. These are the stories about time travel, string theory, black holes, space telescopes, particle accelerators, and other cutting-edge developments. Consider these ideas: Although Einstein's theory of general relativity dates from 1914, it has not been possible to test certain predictions until recently. The Hubble Space Telescope is providing some of the most striking confirmations of the theory, including certain evidence for the existence of black holes, objects that warp space and time so that not even light can escape. Also, the expansion of the universe predicted by the theory of general relativity is now a known rate. General relativity also predicts an even weirder phenomenon called "wormholes" that offer shortcuts to remote reaches of time and space. According to Einstein's theory of special relativity, two twins would age at different rates if one left on a high-speed journey to a distant star and then returned. This experiment has actually been done, not with twins, but with an atomic clock flown around the world. Another fascinating experiment confirming that time slows as speed increases comes from measuring muons at the top and bottom of mountains. A seemingly absurd consequence of quantum mechanics, called "quantum tunneling," makes it possible for objects to materialize through impenetrable barriers. Quantum tunneling happens all the time on the subatomic scale and plays an important role in electronic devices and the nuclear processes that keep the sun shining. Some predictions about the expansion of the universe were so odd that Einstein himself tried to rewrite the mathematics in order to eliminate them. When Hubble discovered the expansion of the universe, Einstein called the revisions the biggest mistake he had ever made. An intriguing thought experiment called "Schrödinger's cat" suggests that a cat in an enclosed box is simultaneously alive and dead under experimental conditions involving quantum phenomena. From Aristotle to the Theory of Everything Professor Wolfson begins with a brief overview of theories of physical reality starting with Aristotle and culminating in Newtonian or "classical" physics. Then he outlines the logic that led to Einstein's theory of special relativity, and the simple yet far-reaching insight on which it rests. With that insight in mind, you move on to consider Einstein's theory of general relativity and its interpretation of gravitation in terms of the curvature of space and time. Professor Wolfson then shows how inquiry into matter at the atomic and subatomic scales led to quandaries that are resolved-or at least clarified-by quantum mechanics, a vision of physical reality so at odds with our experience that it nearly defies language. Bringing relativity and quantum mechanics into the same picture leads to hypotheses about the origin, development, and possible futures of the entire universe, and the possibility that physics can produce a "theory of everything" to account for all aspects of the physical world. Fascinating Incidents and Ideas Along the way, you'll explore these fascinating incidents and ideas: In the 1880s, Albert Michelson and Edward Morley conducted an experiment to determine the motion of the Earth relative to the ether, which was a supposedly imponderable substance pervading all of space. You'll learn about their experiment, its shocking result, and the resulting theoretical crisis. In 1905, a young Swiss patent clerk named Albert Einstein resolved the crisis by discarding the ether concept and asserting the principle of relativity-that the laws of physics are the same for all observers in uniform motion. Relativity implies that the time order of events can be different in different reference frames. Does this wreak havoc with cause and effect? And why does Einstein assert that nothing can go faster than light? Shortly after publishing his 1905 paper on special relativity, Einstein realized that his theory required a fundamental equivalence between mass and energy, which he expressed in the equation E=mc2. Among other things, this famous formula means that the energy contained in a single raisin could power a large city for a whole day. Historically, the path to general relativity followed Einstein's attempt to incorporate gravity into relativity theory, which led to his understanding of gravity not as a force, but as a local manifestation of geometry in curved spacetime. Quantum theory places severe limits on our ability to observe nature at the atomic scale because it implies that the act of observation necessarily disturbs the thing that is being observed. The result is Werner Heisenberg's famous "uncertainty principle." Are quarks, the particles that make up protons and neutrons, the truly elementary particles? What are the three fundamental forces that physicists identify as holding particles together? Could they be manifestations of a single, universal force? A Teaching Legend On his own Middlebury College campus, Professor Wolfson is a teaching legend with an infectious enthusiasm for his subject and a knack for conveying difficult concepts in a way that fosters true understanding. He is the author of an introductory text on physics, a contributor to the esteemed publication Scientific American, and a specialist in interpreting science for the nonspecialist. In this course, Professor Wolfson uses extensive illustrations and diagrams to help bring to life the theories and concepts that he discusses. Thus we highly recommend our DVD version, although Professor Wolfson is mindful of our audio students and carefully describes visual materials throughout his lectures. Professor Richard Wolfson on the Second Edition of Einstein's Relativity: "The first version of this course was produced in 1995. In this new version, I have chosen to spend more time on the philosophical interpretation of quantum physics, and on recent experiments relevant to that interpretation. I have also added a final lecture on the theory of everything and its possible implementation through string theory. The graphic presentations for the DVD version have also been extensively revised and enhanced. But the goal remains the same: to present the key ideas of modern physics in a way that makes them clear to the interested layperson."

    Americans eat more bananas than apples and oranges combined. In others parts of the world, bananas are what keep millions of people alive. But for all its ubiquity, the banana is surprisingly mysterious; nobody knows how bananas evolved or exactly where they originated. Rich cultural lore surrounds the fruit: In ancient translations of the Bible, the 'apple' consumed by Eve is actually a banana (it makes sense, doesn't it?). Entire Central American nations have been said to rise and fall over the banana. But the biggest mystery about the banana today is whether it will survive. A seedless fruit with a unique reproductive system, every banana is a genetic duplicate of the next, and therefore susceptible to the same blights. Today's yellow banana, the Cavendish, is increasingly threatened by such a blight -- and there's no cure in sight. Banana combines a pop-science journey around the globe, a fascinating tale of an iconic American business enterprise, and a look into the alternately tragic and hilarious banana subculture (one does exist) -- ultimately taking us to the high-tech labs where new bananas are literally being built in test tubes, in a race to save the world's most beloved fruit.

    It’s as strange, beautiful and unexpected, as precise and exquisite in its movings, as bees in a hive. I loved it' HELEN MACDONALD, author of H IS FOR HAWKA fascinating, insightful and inspiring account of a novice beekeeper's year of keeping honeybees, which will appeal to readers of H is For Hawk and The Outrun Entering her thirties, Helen Jukes feels trapped in an urban grind of office politics and temporary addresses – disconnected, stressed. Struggling to settle into her latest job and home in Oxford, she realises she needs to effect a change if she’s to create a meaningful life for herself, one that can accommodate comfort and labour and love. Then friends give her the gift of a colony of honeybees – according to folklore, bees freely given bring luck – and Helen embarks on her first full year of beekeeping. But what does it mean to ‘keep’ wild creatures? In learning about the bees, what can she learn of herself? And can travelling inside the hive free her outside it?   As Helen grapples with her role in the delicate, awe-inspiring ecosystem of the hive, the very act of keeping seems to open up new perspectives, deepen friendships old and new, and make her world come alive.  A Honeybee Heart Has Five Openings is at once a fascinating exploration of the honeybee and the hive, the practices of honey-gathering and the history of our observation of bees; and a beautifully wrought meditation on responsibility and care, on vulnerability and trust, on forging bonds and breaking new ground.

    Their numbers are in freefall, dropping by nearly 70 percent in the last sixty years, a billion fewer now than in 1950. Extinction stalks the ocean, and there is a danger that the hundred-million-year-old cries of a seabird colony, rolling around in the bays and headlands of high latitudes, will this century become but a memory.

    In this far-reaching narrative, Weisman explains how our massive infrastructure would collapse and finally vanish without human presence; which everyday items may become immortalized as fossils; how copper pipes and wiring would be crushed into mere seams of reddish rock; why some of our earliest buildings might be the last architecture left; and how plastic, bronze sculpture, radio waves, and some man-made molecules may be our most lasting gifts to the universe.The World Without Us reveals how, just days after humans disappear, floods in New York's subways would start eroding the city's foundations, and how, as the world's cities crumble, asphalt jungles would give way to real ones. It describes the distinct ways that organic and chemically treated farms would revert to wild, how billions more birds would flourish, and how cockroaches in unheated cities would perish without us. Drawing on the expertise of engineers, atmospheric scientists, art conservators, zoologists, oil refiners, marine biologists, astrophysicists, religious leaders from rabbis to the Dalai Lama, and paleontologists—who describe a prehuman world inhabited by megafauna like giant sloths that stood taller than mammoths—Weisman illustrates what the planet might be like today, if not for us.From places already devoid of humans (a last fragment of primeval European forest; the Korean DMZ; Chernobyl), Weisman reveals Earth's tremendous capacity for self-healing. As he shows which human devastations are indelible, and which examples of our highest art and culture would endure longest, Weisman's narrative ultimately drives toward a radical but persuasive solution that needn't depend on our demise. It is narrative nonfiction at its finest, and in posing an irresistible concept with both gravity and a highly readable touch, it looks deeply at our effects on the planet in a way that no other book has.

    Meredith May recalls the first time a honeybee crawled on her arm. She was five years old, her parents had recently split and suddenly she found herself in the care of her grandfather, an eccentric beekeeper who made honey in a rusty old military bus in the yard. That first close encounter was at once terrifying and exhilarating for May, and in that moment she discovered that everything she needed to know about life and family was right before her eyes, in the secret world of bees.May turned to her grandfather and the art of beekeeping as an escape from her troubled reality. Her mother had receded into a volatile cycle of neurosis and despair and spent most days locked away in the bedroom. It was during this pivotal time in May's childhood that she learned to take care of herself, forged an unbreakable bond with her grandfather and opened her eyes to the magic and wisdom of nature.The bees became a guiding force in May's life, teaching her about family and community, loyalty and survival and the unequivocal relationship between a mother and her child. Part memoir, part beekeeping odyssey, The Honey Bus is an unforgettable story about finding home in the most unusual of places, and how a tiny, little-understood insect could save a life.

    The evidence insists that Aboriginal people right across the continent were using domesticated plants, sowing, harvesting, irrigating and storing – behaviours inconsistent with the hunter-gatherer tag. Gerritsen and Gammage in their latest books support this premise but Pascoe takes this further and challenges the hunter-gatherer tag as a convenient lie. Almost all the evidence comes from the records and diaries of the Australian explorers, impeccable sources.

    See ISBN 9780465094646History is full of strange animal stories invented by the brightest and most influential, from Aristotle to Disney. But when it comes to understanding animals, we’ve got a long way to go.Whether we’re watching a viral video of romping baby pandas or looking at a picture of penguins ‘holding hands’, we often project our own values – innocence, abstinence, hard work – onto animals. So you’ve probably never considered that moose get drunk and that penguins are notorious cheats.In The Unexpected Truth About Animals Zoologist Lucy unravels many such myths – that eels are born from sand, that swallows hibernate under water, and that bears gave birth to formless lumps that are licked into shape by their mothers – to show that the stories we create reveal as much about us as they do about the animals.Astonishing, illuminating and laugh-out-loud funny.

    In her wise and elegant new book, Jane Goodall blends her experience in nature with her enthusiasm for botany to give readers a deeper understanding of the world around us.Long before her work with chimpanzees, Goodall's passion for the natural world sprouted in the backyard of her childhood home in England, where she climbed her beech tree and made elderberry wine with her grandmother. The garden her family began then, she continues to enjoy today. SEEDS OF HOPE takes us from England to Goodall's home-away-from-home in Africa, deep inside the Gombe forest, where she and the chimpanzees are enchanted by the fig and plum trees they encounter. She introduces us to botanists around the world, as well as places where hope for plants can be found, such as The Millennium Seed Bank, where one billion seeds are preserved. She shows us the secret world of plants with all their mysteries and potential for healing our bodies as well as Planet Earth.Looking at the world as an adventurer, scientist, and devotee of sustainable foods and gardening-and setting forth simple goals we can all take to protect the plants around us-Jane Goodall delivers an enlightening story of the wonders we can find in our own backyards.

    But why are they on the rise?     Science writer Moises Velasquez-Manoff offers a new and controversial way of thinking about autoimmune disease—one that may foster a paradigm shift in the way we think about health and hygiene.     In the early twentieth century, the dawn of improved hygiene, water treatment, vaccines, and antibiotics saved countless lives, eradicating diseases that had plagued humanity for millennia. But in the wake of this triumph, a new threat arose: The human immune system began to malfunction.     A growing body of evidence suggests that the very steps we took to cure these maladies have also eradicated organisms that once kept our bodies in balance. To combat this “epidemic of absence,” a group of scientists has begun deliberately reintroducing parasitic worms—helminthes—to calm the immune system of their hosts. This book takes a close look at the scientists at the vanguard of “worm therapy,” which has been proven to not only preempt immune malfunction, but to send a number of disorders—from Crohn’s Disease to multiple sclerosis to asthma—into remission.     Exploring the greater context of rampant immune system dysfunction in the developed world, and its implications for developing countries, Velasquez-Manoff offers an eye-opening and elegant portrait of science’s new view of the human organism.
