Recalling his nearly two decades as Hawking's collaborator and friends, Leonard Mlodinow brings this complex man into focus in a unique and deeply personal portrayal. We meet Hawking the genius, who pours his mind into uncovering the mysteries of the universe--ultimately formulating a pathbreaking theory of black holes that reignites the discipline of cosmology and paves the way for physicists to investigate the origins of the universe in completely new ways. We meet Hawking the colleague, a man whose illness leaves him able to communicate at only six words per minute but who expends the effort to punctuate his conversations with humor. And we meet Hawking the friend, who can convey volumes with a frown, a smile, or simply a raised eyebrow.Mlodinow puts us in the room as Hawking indulges his passion for wine and curry; shares his feelings on love, death, and disability; and grapples with deep questions of philosophy and physics. Whether depicting Hawking's devotion to his work or demonstrating how he would make spur of the moment choices, such as punting on the River Cam (despite the risk the jaunt posed), or spinning tales of Hawking defiantly urinating in the hedges outside a restaurant that doesn't have a wheelchair accessible toilet, Mlodinow captures his indomitable spirit. This moving account of a friendship offers us invaluable lessons from one of physics' greatest practitioners about life, the universe, and the ability to overcome daunting obstacles.

    . . . Readers will never again look into the night sky the same way.” —MICHAEL SHERMER, author of The Believing Brain on Parallax: The Race to Measure the CosmosIn 1930, Edwin Hubble announced the greatest discovery in the history of astronomy since Galileo first turned a telescope to the heavens. The galaxies, previously believed to float serenely in the void, are in fact hurtling apart at an incredible speed; the universe is expanding. This stunning discovery was the culmination of a decades-long arc of scientific and technical advancement. In its shadow lies an untold, yet equally fascinating, backstory whose cast of characters illuminates the gritty, hard-won nature of scientific progress.The path to a broader mode of cosmic observation was blazed by a cadre of 19th-century amateur astronomers and inventors, galvanized by the advent of photography, spectral analysis, and innovative technology to create the entirely new field of astrophysics. From William Bond, who turned his home into a functional observatory, to John and Henry Draper, a father and son team who were trailblazers of astrophotography and spectroscopy, to geniuses of invention such as Léon Foucault, and George Hale, who founded the Mount Wilson Observatory, Hirshfeld reveals the incredible stories—and the ambitious dreamers—behind the birth of modern astronomy.Alan Hirshfeld, Professor of Physics at the University of Massachusetts Dartmouth and an Associate of the Harvard College Observatory, is the author of Parallax: The Race to Measure the Cosmos, The Electric Life of Michael Faraday, and Eureka Man: The Life and Legacy of Archimedes.

    Now it's one of the fastest-growing fields in astronomy with thousands of exoplanets discovered to date, and the number is rising fast.These new-found worlds are more alien than anything in fiction. Planets larger than Jupiter with years lasting a week; others with two suns lighting their skies, or with no sun at all. Planets with diamond mantles supporting oceans of tar; possible Earth-sized worlds with split hemispheres of perpetual day and night; waterworlds drowning under global oceans and volcanic lava planets awash with seas of magma. The discovery of this diversity is just the beginning. There is a whole galaxy of possibilities. The Planet Factory tells the story of these exoplanets. Each planetary system is different, but in the beginning most if not all young stars are circled by clouds of dust, specks that come together in a violent building project that can form colossal worlds hundreds of times the size of the Earth. The changing orbits of young planets risk dooming any life evolving on neighbouring worlds or, alternatively, can deliver the key ingredients needed to seed its beginnings. Planet formation is one of the greatest construction schemes in the Universe, and it occurred around nearly every star you see. Each results in an alien landscape, but is it possible that one of these could be like our own home world?

    With thousands of breathtaking photographs and unique visual catalogues of the features and phenomena that take place on Earth -- such as rocks, minerals, and mountains to tropical rain forests and the different types of clouds -- Earth contains the most up-to-date ideas on how our world works, a compelling review on the health of the planet, and unbelievable images of the world's most stunning features.

    Then, in 2005, astronomer Mike Brown made the discovery of a lifetime: a tenth planet, Eris, slightly bigger than Pluto. But instead of its resulting in one more planet being added to our solar system, Brown’s find ignited a firestorm of controversy that riled the usually sedate world of astronomy and launched him into the public eye. The debate culminated in the demotion of Pluto from real planet to the newly coined category of “dwarf” planet. Suddenly Brown was receiving hate mail from schoolchildren and being bombarded by TV reporters—all because of the discovery he had spent years searching for and a lifetime dreaming about.Filled with both humor and drama, How I Killed Pluto and Why It Had It Coming is Mike Brown’s engaging first-person account of the most tumultuous year in modern astronomy—which he inadvertently caused. As it guides readers through important scientific concepts and inspires us to think more deeply about our place in the cosmos, it is also an entertaining and enlightening personal story: While Brown sought to expand our understanding of the vast nature of space, his own life was changed in the most immediate, human ways by love, birth, and death. A heartfelt and personal perspective on the demotion of everyone’s favorite farflung planet, How I Killed Pluto and Why It Had It Coming is the book for anyone, young or old, who has ever dreamed of exploring the universe—and who among us hasn’t?

    He was usually credited as Camille Flammarion. He was a prolific author of more than fifty titles, including popular science works about astronomy, several notable early science fiction novels, and several works about Spiritualism and related topics. He also published the magazine L'Astronomie, starting in 1882. He maintained a private observatory at Juvisy-sur-Orge, France. He was a founder and the first president of the Socit Astronomique de France, which originally had its own independent journal, BSAF (Bulletin de la Socit Astronomique de France), first published in 1887. He was the first to suggest the names Triton and Amalthea for moons of Neptune and Jupiter, respectively, although these names were not officially adopted until many decades later. His spiritualism studies influenced also some of his science fiction. Other than that his writing about other worlds adhered fairly closely to then current ideas in evolutionary theory and astronomy. Amongst his other works are: The Atmosphere (1873), Popular Astronomy (1907), Astronomy for Amateurs (1904), Omega: The Last Days of the World and Death and its Mystery.

    Illustrated throughout with detailed photographs and illustrations, and using clear, easy-to-follow text, The Practical Astronomer takes you on a step-by-step journey from the basics of what can be seen with the naked eye, to how you can view more distant objects such as the planets of the solar system, and even galaxies far, far away-all in your own backyard.

    "A stunning memoir from the astronaut who spent a record-breaking year aboard the International Space Station – a candid account of his remarkable voyage, the journeys that preceded it, and his colorful formative years." Inside book cover comments.

    All the chemical elements on earth except hydrogen-including the ones in our bodies-have been processed inside stars, scattered across the universe in great stellar explosions, and recycled to become new stars, planets, and parts of us. In this engrossing book, John and Mary Gribbin relate the developments in twentieth-century astronomy that have led to this shattering realization. They begin their account in the 1920s, when astronomers discovered that the oldest stars are chiefly composed of the primordial elements hydrogen and helium, produced in the birth of the universe in a Big Bang. They then describe the seminal work of the 1950s and 1960s, which unlocked the secret of how elements are "cooked" by nuclear fusion inside stars. The heart of the story is their discussion of supernovae, only recently understood as great stellar explosions in which the resulting ash is spread far and wide through the cosmos, forming new generations of stars, planets, and people. Focusing on the relationship between the universe and the Earth, the authors eloquently explain how the physical structure of the universe has produced conditions ideal for life.

    On that day, astronomer Arthur Eddington and his team observed a solar eclipse and found something extraordinary: gravity bends light, just as Einstein predicted. The finding confirmed the theory of general relativity, fundamentally changing our understanding of space and time.A century later, another group of astronomers is performing a similar experiment on a much larger scale. The Event Horizon Telescope, a globe-spanning array of radio dishes, is examining space surrounding Sagittarius A*, the supermassive black hole at the center of the Milky Way. As Ron Cowen recounts, the foremost goal of the experiment is to determine whether Einstein was right on the details. Gravity lies at the heart of what we don't know about quantum mechanics, but tantalizing possibilities for deeper insight are offered by black holes. By observing starlight wrapping around Sagittarius A*, the telescope will not only provide the first direct view of an event horizon--a black hole's point of no return--but will also enable scientists to test Einstein's theory under the most extreme conditions.Gravity's Century shows how we got from the pivotal observations of the 1919 eclipse to the Event Horizon Telescope, and what is at stake today. Breaking down the physics in clear and approachable language, Cowen makes vivid how the quest to understand gravity is really the quest to comprehend the universe.

    Told through an examination of animal and plant life today - with occasional juxtapositions of extinct fossil forms to reveal the origin of living creatures - "Life on Earth" is an astonishing pageant of life, with a cast of characters drawn from the whole range of living animals the world over. Attenborough's perceptive, dynamic approach to the evolution of some four million species of living organisms that populate the planet is to trace the most significant thread in the history of each major group. He then proceeds to explain from the evidence of living representatives and fossil remains why certain animals adapted and survived, evolved to more complex and "higher" forms of life, while others, by some inherent limitation imposed by their physiology or structure, failed and became extinct. "Life on Earth" is a book of wonders. A model of clarity and ease as a guide, Attenborough takes the reader around the world with him into jungles where orchids have petals that "impersonate" wasps to attract pollinating insects; to Australia, where honeypot ants force feed nectar to workers of a special caste, then hang them up by their forelegs like living storage jars; to remote mountains in Japan where little monkeys called macaques have learned to combat the winter snows by bathing in hot volcanic springs.

    After Congress viewed photos of Yosemite, President Lincoln was moved to sign a bill that paved the way for the U.S. National Park Service, which was founded in 1916 and is now celebrating its centennial. In Treasured Lands: A Photographic Odyssey Through America's National Parks, photographer QT Luong pays tribute to the millions of acres of protected wilderness in our country's 59 national parks. Luong, who is featured in Ken Burns's and Dayton Duncan's documentary The National Parks: America's Best Idea, is one the most prolific photographers working in the national parks and the only one to have made large-format photographs in each of them. In an odyssey that spanned more than 20 years and 300 visits, Luong focused his lenses on iconic landscapes and rarely seen remote views, presenting his journey in this sumptuous array of more than 500 breathtaking images. Accompanying the collection of scenic masterpieces is a guide that includes maps of each park, as well as extended captions that detail where and how the photographs were made. Designed to inspire visitors to connect with the parks and invite photographers to re-create these landscapes, the guide also provides anecdotal observations that give context to the pictures and convey the sheer scope of Luong's extraordinary odyssey. Including an introduction by award-winning author and documentary filmmaker Dayton Duncan, Treasured Lands is a rich visual tour of the U.S. National Parks and an invaluable guide from a photographer who hiked - or paddled, dived, skied, snowshoed, and climbed - each park, shooting in all kinds of terrain, in all seasons, and at all times of day. QT Luong's timeless gallery of the nation's most revered landscapes beckons to nature lovers, armchair travelers, and photography enthusiasts alike, keeping America's natural wonders within reach.

    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.

    Anticipation of the rare celestial event sparked a worldwide competition among aspiring global superpowers, each sending their own scientific expeditions to far-flung destinations to time the planet’s trek. These pioneers used the “Venus Transit” to discover the physical dimensions of the solar system and refine the methods of discovering longitude at sea. In this fast-paced narrative, Mark Anderson reveals the stories of three Venus Transit voyages--to the heart of the Arctic, the New World, and the Pacific—that risked every mortal peril of a candlelit age. With time running out, each expedition struggles to reach its destination—a quest that races to an unforgettable climax on a momentous summer day when the universe suddenly became much larger than anyone had dared to imagine.The Day the World Discovered the Sun tells an epic story of the enduring human desire to understand our place in the universe.
