QED--the edited version of four lectures on quantum electrodynamics that Feynman gave to the general public at UCLA as part of the Alix G. Mautner Memorial Lecture series--is perhaps the best example of his ability to communicate both the substance and the spirit of science to the layperson.The focus, as the title suggests, is quantum electrodynamics (QED), the part of the quantum theory of fields that describes the interactions of the quanta of the electromagnetic field-light, X rays, gamma rays--with matter and those of charged particles with one another. By extending the formalism developed by Dirac in 1933, which related quantum and classical descriptions of the motion of particles, Feynman revolutionized the quantum mechanical understanding of the nature of particles and waves. And, by incorporating his own readily visualizable formulation of quantum mechanics, Feynman created a diagrammatic version of QED that made calculations much simpler and also provided visual insights into the mechanisms of quantum electrodynamic processes.In this book, using everyday language, spatial concepts, visualizations, and his renowned "Feynman diagrams" instead of advanced mathematics, Feynman successfully provides a definitive introduction to QED for a lay readership without any distortion of the basic science. Characterized by Feynman's famously original clarity and humor, this popular book on QED has not been equaled since its publication.

    Most scientists didn't recognize the import of Hawking's claims, but Leonard Susskind and Gerard t'Hooft realized the threat, and responded with a counterattack that changed the course of physics.The Black Hole War is the thrilling story of their united effort to reconcile Hawking's revolutionary theories of black holes with their own sense of reality -- effort that would eventually result in Hawking admitting he was wrong, paying up, and Susskind and t'Hooft realizing that our world is a hologram projected from the outer boundaries of space.A brilliant book about modern physics, quantum mechanics, the fate of stars and the deep mysteries of black holes, Leonard Susskind's account of the Black Hole War is mind-bending and exhilarating reading.

    

    Beyond tells the epic story of humanity leaving home—and how humans will soon thrive in the vast universe beyond the earth.A dazzling and propulsive voyage through space and time, Beyond reveals how centuries of space explorers—from the earliest stargazers to today’s cutting-edge researchers—all draw inspiration from an innate human emotion: wanderlust. This urge to explore led us to multiply around the globe, and it can be traced in our DNA.Today, the urge to discover manifests itself in jaw-dropping ways: plans for space elevators poised to replace rockets at a fraction of the cost; experiments in suspending and reanimating life for ultra-long-distance travel; prototypes for solar sails that coast through space on the momentum of microwaves released from the Earth. With these ventures, private companies and entrepreneurs have the potential to outpace NASA as the leaders in a new space race.Combining expert knowledge of astronomy and avant-garde technology, Chris Impey guides us through the heady possibilities for the next century of exploration. In twenty years, a vibrant commercial space industry will be operating. In thirty years, there will be small but viable colonies on the Moon and Mars. In fifty years, mining technology will have advanced enough to harvest resources from asteroids. In a hundred years, a cohort of humans born off-Earth will come of age without ever visiting humanity’s home planet. This is not the stuff of science fiction but rather the logical extension of already available technologies.Beyond shows that space exploration is not just the domain of technocrats, but the birthright of everyone and the destiny of generations to come. To continue exploration is to ensure our survival. Outer space, a limitless unknown, awaits us.

    In an unexpectedly zany adventure that took the author the equivalent of 3.3 times around the world, the result is a tale of theft, wartime atrocities, insane millionaires, intrigue in the Middle East, and skinny dipping.The Labrador Duck is often mentioned in the same breath as the Passenger Pigeon, the Dodo, and the Great Auk—great species that once roamed the planet. The Labrador Duck became extinct somewhere around 1875. It is the most enigmatic bird in North America, partially because it bred so far north that no record exists of its breeding, and partially because it became extinct almsot before we noted it was in decline. The Curse of the Labrador Duck chronicles Chilton's adventures while attempting to examine every stuffed specimen of the species, do genetic analysis of every Labrador Duck egg, and visit every North American site where the duck was shot.When Chilton began his investigation, there were thought to be about fifty specimens scattered amongst the museums of Europe, North America, and the Middle East. However, as his study advanced, it was clear that some specimens had been lost to war and theft, and others were secreted away in far-flung collections overseen by miserly curators. After travelling the equivalent of more than three times around the world, Chilton was able to examine what amounted to fifty-five specimens in total, although one turned out to be a forgery and several others had been tampered with by unscrupulous taxidermists. Regrettably, genetic analysis showed that none of the eggs attributed to the Labrador Duck were genuine, even those that had escaped the bombing of Dresden. On the positive side, the author earned numerous hangovers, swam naked in a glacier-fed stream, dined with Russian gangsters, and was able to narrowly avoid arrest in New York City.

    The planet most like ours, it has still been thought impossible to reach, let alone explore and inhabit.Now with the advent of a revolutionary new plan, all this has changed. leading space exploration authority Robert Zubrin has crafted a daring new blueprint, Mars Direct, presented here with illustrations, photographs, and engaging anecdotes.The Case for Mars is not a vision for the far future or one that will cost us impossible billions. It explains step-by-step how we can use present-day technology to send humans to Mars within ten years; actually produce fuel and oxygen on the planet's surface with Martian natural resources; how we can build bases and settlements; and how we can one day "terraform" Mars--a process that can alter the atmosphere of planets and pave the way for sustainable life.

    Every concrete building and paved road on Earth, every computer screen and silicon chip, is made from sand. From Egypt's pyramids to the Hubble telescope, from the world's tallest skyscraper to the sidewalk below it, from Chartres' stained-glass windows to your iPhone, sand shelters us, empowers us, engages us, and inspires us. It's the ingredient that makes possible our cities, our science, our lives--and our future.And, incredibly, we're running out of it.The World in a Grain is the compelling true story of the hugely important and diminishing natural resource that grows more essential every day, and of the people who mine it, sell it, build with it--and sometimes, even kill for it. It's also a provocative examination of the serious human and environmental costs incurred by our dependence on sand, which has received little public attention. Not all sand is created equal: Some of the easiest sand to get to is the least useful. Award-winning journalist Vince Beiser delves deep into this world, taking readers on a journey across the globe, from the United States to remote corners of India, China, and Dubai to explain why sand is so crucial to modern life. Along the way, readers encounter world-changing innovators, island-building entrepreneurs, desert fighters, and murderous sand pirates. The result is an entertaining and eye-opening work, one that is both unexpected and involving, rippling with fascinating detail and filled with surprising characters.

    Wilson Literary Science Writing Award "A masterly synthesis of scientific research and personal observation."-Wall Street JournalLegends don't come close to capturing the incredible story of the coyote In the face of centuries of campaigns of annihilation employing gases, helicopters, and engineered epidemics, coyotes didn't just survive, they thrived, expanding across the continent from Alaska to New York. In the war between humans and coyotes, coyotes have won, hands-down. Coyote America is the illuminating five-million-year biography of this extraordinary animal, from its origins to its apotheosis. It is one of the great epics of our time.

    A true tale of beauty and obsession, smugglers and scientists, and nature’s most enigmatic creature.

    Birds of prey have an aura that few other creatures have. In the acclaimed Hawks in Flight, Pete Dunne showed what birds of prey look like. In The Wind Masters, he shows what it is like to be a bird of prey. He takes us inside the lives and minds of all thirty-four species of diurnal raptors found in North America -- hawks, falcons, eagles, vultures, the osprey, and the harrier -- and shows us how each bird sees the world, hunts its prey, finds and courts its mate, rears its young, grows up, grows old, and dies. Vividly written, and beautifully illustrated by David Sibley, The Wind Masters is a brilliant work of narrative natural history in the tradition of Peter Matthiessen's The Wind Birds and Barry Lopez's Of Wolves and Men.

    From New England aquarium tanks to the reefs of French Polynesia and the Gulf of Mexico, she has befriended octopuses with strikingly different personalities—gentle Athena, assertive Octavia, curious Kali, and joyful Karma. Each creature shows her cleverness in myriad ways: escaping enclosures like an orangutan; jetting water to bounce balls; and endlessly tricking companions with multiple “sleights of hand” to get food.Scientists have only recently accepted the intelligence of dogs, birds, and chimpanzees but now are watching octopuses solve problems and are trying to decipher the meaning of the animal’s color-changing techniques. With her “joyful passion for these intelligent and fascinating creatures” (Library Journal Editors’ Spring Pick), Montgomery chronicles the growing appreciation of this mollusk as she tells a unique love story. By turns funny, entertaining, touching, and profound, The Soul of an Octopus reveals what octopuses can teach us about the meeting of two very different minds.

    Sir Douglas Mawson is remembered as the young Australian who would not go to the South Pole with Robert Scott in 1911, choosing instead to lead his own expedition on the less glamorous mission of charting nearly 1,500 miles of Antarctic coastline and claiming its resources for the British Crown. His party of three set out through the mountains across glaciers in 60-mile-per-hour winds. Six weeks and 320 miles out, one man fell into a crevasse, along with the tent, most of the equipment, all of the dogs' food, and all except a week's supply of the men's provisions.Mawson's Will is the unforgettable story of one man's ingenious practicality and unbreakable spirit and how he continued his meticulous scientific observations even in the face of death. When the expedition was over, Mawson had added more territory to the Antarctic map than anyone else of his time. Thanks to Bickel's moving account, Mawson can be remembered for the vision and dedication that make him one of the world's great explorers.

    It explains all this and much more. It discloses the best time to have a sex change, how to have a virgin birth, when to seduce your sisters or eat your lover. Quirky and brilliant, it takes as its starting point all creatures great and small worried about their bizarre sex lives, and the letters they write to the wise Dr Tatiana, the only agony aunt in all creation with a prodigious knowledge of both natural history and evolutionary biology.

    Weaving together the cosmos' history and our own in an expanding intellectual adventure story, Dark Matter and the Dinosaurs takes us from the mysteries of dark matter and our cosmic environment to the conditions for life on Earth.Sixty-six million years ago, an object the size of a city descended from space to crash into Earth, creating a cataclysm that killed off the dinosaurs, along with three-quarters of the other species on the planet. What was its origin? Randall proposes it was a comet that was dislodged from its orbit as the Solar System passed through a disk of dark matter that is embedded in the plane of the Milky Way. Her research challenges the usual assumptions about the simple nature of dark matter and demonstrates how scientists formulate and establish new ideas. In a sense, it might have been dark matter that killed the dinosaurs.With her unique and wide-ranging perspective, Randall connects dark matter to the history of the world in the broadest terms. Bringing in pop culture and social and political viewpoints, she shares with us the latest findings—established and speculative—regarding dark matter, the cosmos, the galaxy, asteroids, comets, and impacts, as well as life's development and extinctions. Randall makes clear how connected the planet is to the makeup of the Universe, but also how fragile our place in the Universe, which evolved over billions of years, might be.In this brilliant and fresh exploration of our cosmic environment, Professor Randall explains the underlying science of our world in the breathtaking tale of a Universe in which the small and the large, the visible and the hidden are intimately related. Dark Matter and the Dinosaurs illuminates the deep relationships that are critical to our world as well as the astonishing beauty of the structures and connections that surround us. It's impossible to read this book and look at either Earth or sky again in the same way.
