These luminous, entertaining essays travel both the vastness of the cosmos and the intimacy of the human mind, posing such fascinating questions as how did the universe originate and how will it end, and how can we meld science and compassion to meet the challenges of the coming century? Here, too, is a rare, private glimpse of Sagan's thoughts about love, death, and God as he struggled with fatal disease. Ever forward-looking and vibrant with the sparkle of his unquenchable curiosity, Billions & Billions is a testament to one of the great scientific minds of our day.

    We watch him navigate a fraught relationship with a lonely uncle in jail who—as he degenerates into madness— continues to plead for the support of his conflicted nephew. And we cringe as he gets outed as a “moby” at a Tea Party rally. In moments like these, we can’t help but ask ourselves: How far would we go for our own family members, and when is someone simply too far gone to save? Are there truly “bad people,” and if so, should we change them? With a perfect combination of humor and pathos, these essays, peppered with Kreider’s signature cartoons, leave us with newfound wisdom and a unique prism through which to examine our own chaotic journeys through life.Uncompromisingly candid, sometimes mercilessly so, these comically illustrated essays are rigorous exercises in self-awareness and self-reflection. These are the conversations you have only with best friends or total strangers, late at night over drinks, near closing time.

    Over the next two decades, Copernicus expanded his theory through hundreds of observations, while compiling in secret a book-length manuscript that tantalized mathematicians and scientists throughout Europe. For fear of ridicule, he refused to publish.In 1539, a young German mathematician, Georg Joachim Rheticus, drawn by rumors of a revolution to rival the religious upheaval of Martin Luther's Reformation, traveled to Poland to seek out Copernicus. Two years later, the Protestant youth took leave of his aging Catholic mentor and arranged to have Copernicus's manuscript published, in 1543, as De revolutionibus orbium coelestium (On the Revolutions of the Celestial Spheres)-the book that forever changed humankind's place in the universe.In her elegant, compelling style, Dava Sobel chronicles, as nobody has, the conflicting personalities and extraordinary discoveries that shaped the Copernican Revolution. At the heart of the book is her play And the Sun Stood Still, imagining Rheticus's struggle to convince Copernicus to let his manuscript see the light of day. As she achieved with her bestsellers Longitude and Galileo's Daughter, Sobel expands the bounds of narration, giving us an unforgettable portrait of scientific achievement, and of the ever-present tensions between science and faith.

    The fantastic journey began in 1977, before the first episode of Cosmos aired. The mission was planned as a grand tour beyond the moon; beyond Mars, Jupiter, and Saturn; and maybe even into interstellar space. The fact that it actually happened makes this humanity's greatest space mission.In The Interstellar Age, award-winning planetary scientist Jim Bell reveals what drove and continues to drive the members of this extraordinary team, including Ed Stone, Voyager's chief scientist and the one-time head of NASA's Jet Propulsion Lab; Charley Kohlhase, an orbital dynamics engineer who helped to design many of the critical slingshot maneuvers around planets that enabled the Voyagers to travel so far; and the geologist whose Earth-bound experience would prove of little help in interpreting the strange new landscapes revealed in the Voyagers' astoundingly clear images of moons and planets.Speeding through space at a mind-bending eleven miles a second, Voyager 1 is now beyond our solar system's planets. It carries with it artifacts of human civilization. By the time Voyager passes its first star in about 40,000 years, the gold record on the spacecraft, containing various music and images including Chuck Berry's "Johnny B. Goode," will still be playable.

    How does Jane Goodall’s relationship with her dog Rusty inform her thinking about our relationship to other species? Which time and place would Jared Diamond most prefer to live in, in light of his work on the role of chance in history? What does driving a sports car have to do with Steven Weinberg’s quest for the “theory of everything”? Physicist and journalist Stefan Klein’s intimate conversations with nineteen of the world’s best-known scientists (including three Nobel Laureates) let us listen in as they talk about their paradigm-changing work—and how it is deeply rooted in their daily lives. • Cosmologist Martin Rees on the beginning and end of the world • Evolutionary biologist Richard Dawkins on egoism and selflessness • Neuroscientist V. S. Ramachandran on consciousness • Molecular biologist Elizabeth Blackburn on aging • Philosopher Peter Singer on morality • Physician and social scientist Nicholas Christakis on human relationships • Biochemist Craig Venter on the human genome • Chemist and poet Roald Hoffmann on beauty

    He had eighty seconds to exceed the speed of sound and begin the climb to a target no civilian pilot had ever reached. There was a chance he would not come back alive. If he did, he would make history as the world’s first commercial astronaut. The spectacle defied reason, the result of an improbable contest dreamed up by entrepreneur Peter Diamandis, whose vision for a new race to space – requiring small teams to do what only the world’s largest governments had done before – had been dismissed as fantastical. The tale begins in Mount Vernon, N.Y. Diamandis was the son of hard working Greek immigrants who wanted their science prodigy to do the family proud and become a doctor. Peter was a dutiful son, but from the time he was eight years old, staying up late to watch Apollo 11 land on the moon, he had one goal: getting to space. He started a national student space club while at MIT. He launched a rocket company in Houston while getting a medical degree from Harvard - a degree he pursued to improve his chances of becoming an astronaut. But when he realized NASA was winding down manned space flight, Diamandis set out on one of the great entrepreneurial adventure stories of our time. If the government wouldn’t send him to space, he would create a private spaceflight industry and get there himself.In the 1990s, the idea of private space flight was the stuff of science fiction. The undaunted Diamandis found inspiration in an unlikely place: the first golden age of aviation. Reading Charles Lindbergh’s The Spirit of St. Louis, Diamandis was stunned that the aviator had attempted the first transatlantic flight from New York to Paris to win a $25,000 prize. The historic flight galvanized the commercial airline industry. Why, Diamandis thought, couldn’t a similar contest be held for space flight? In 1996, standing under the arch of St. Louis – the city where Lindbergh found his backers - Diamandis announced the $10 million Xprize. To win, a privately funded team would have to build and fly a manned rocket into space twice – in two weeks. The deadline: December 31, 2004.   On a brilliant morning in the Mojave Desert, with little time to spare, a bullet-shaped rocket called SpaceShipOne was launched. The story of SS1, and other scrappy teams in the hunt – all spurred by Diamandis as he struggled to keep the prize afloat – became a testament to the American spirit of ingenuity and oversized dreams. The winning of the Xprize marked the end of the government’s monopoly over space.   Julian Guthrie, author of The Billionaire and The Mechanic, an acclaimed bestselling account of Oracle CEO Larry Ellison’s pursuit of the America’s Cup, thought she knew about obsessive pursuits, but the XPrize race spurred another level of drama, sacrifice, and technical wizardry. With Diamandis’ cooperation, Guthrie had access to all of the players – from Richard Branson and John Carmack to Burt Rutan – and has melded their stories into a spellbinding narrative, a combination of Rocket Boys and The New New Thing. In the end, as Diamandis dreamed, the result wasn’t just a victory for one team; it was the foundation for a new industry, including SpaceX, Virgin Galactic, Blue Origin and others. Today, SpaceShipOne hangs in the Smithsonian’s Air and Space Museum, above the Apollo 11 capsule and next to Lindbergh’s Spirit of St. Louis plane.

    With his trademark humor and frankness, Alan Alda explains what makes the out-of-the-box techniques he developed after his years as the host of Scientific American Frontiers so effective. This book reveals what it means to be a true communicator, and how we can communicate better, in every aspect of our lives—with our friends, lovers, and families, with our doctors, in business settings, and beyond.

    After settling down in Texas, Anousheh built a computer technology firm from the ground up, which eventually realized a net worth of $750 million and ultimately allowed her to achieve her childhood dream of spaceflight. In her groundbreaking role as the first-ever female commercial spaceflight participant, her story became politicized and fraught with the prejudices and obstacles she had to overcome as an Iranian woman, culminating in a debate over whether she would be allowed to display both the American and Iranian flags on the sleeve of her spacesuit.After her return to Earth, Anousheh started The Ansari Foundation, a quickly growing nonprofit which supports social entrepreneurship, and is especially committed to ensuring the freedom of women around the world and supporting female entrepreneurs. Ultimately, this evocative story shows the triumph of a woman who has become a role model to people around the globe struggling to overcome economic and cultural barriers, as well as those dreamers who look upon the stars and wish to soar among them.

    xn + yn = zn, where n represents 3, 4, 5, ...no solution"I have discovered a truly marvelous demonstration of this proposition which this margin is too narrow to contain."With these words, the seventeenth-century French mathematician Pierre de Fermat threw down the gauntlet to future generations.  What came to be known as Fermat's Last Theorem looked simple; proving it, however, became the Holy Grail of mathematics, baffling its finest minds for more than 350 years.  In Fermat's Enigma--based on the author's award-winning documentary film, which aired on PBS's "Nova"--Simon Singh tells the astonishingly entertaining story of the pursuit of that grail, and the lives that were devoted to, sacrificed for, and saved by it.  Here is a mesmerizing tale of heartbreak and mastery that will forever change your feelings about mathematics.

    Why is the universe expanding at an ever faster rate? What is the nature of the "dark matter" that makes up almost a quarter of the universe? Why does the universe appear fine-tuned for life? Are there others besides our own? Ananthaswamy soon finds himself at the ends of the earth--in remote and sometimes dangerous places. Take the Atacama Desert in the Chilean Andes, one of the coldest, driest places on the planet, where not even a blade of grass can survive. Its spectacularly clear skies and dry atmosphere allow astronomers to gather brilliant images of galaxies billions of light-years away. Ananthaswamy takes us inside the European Southern Observatory's Very Large Telescope on Mount Paranal, where four massive domes open to the sky each night "like dragons waking up."He also takes us deep inside an abandoned iron mine in Minnesota, where half-mile-thick rock shields physicists as they hunt for elusive dark matter particles. And to the East Antarctic Ice Sheet, where engineers are drilling 1.5 miles into the clearest ice on the planet. They're building the world's largest neutrino detector, which could finally help reconcile quantum physics with Einstein's theory of general relativity.The stories of the people who work at these and other dramatic research sites--from Lake Baikal in Siberia to the Indian Astronomical Observatory in the Himalayas to the subterranean lair of the Large Hadron Collider--make for a compelling new portrait of the universe and our quest to understand it. An atmospheric, engaging, and illuminating read, "The Edge of Physics" depicts science as a human process, bringing cosmology back down to earth in the most vivid terms.

    But soon, Earth's isolation could come to an end. Over the past two decades, astronomers have discovered thousands of planets orbiting other stars. Some of these exoplanets may be mirror images of our own world. And more are being found all the time.Yet as the pace of discovery quickens, an answer to the universe's greatest riddle still remains just out of reach: Is the great silence and emptiness of the cosmos a sign that we and our world are somehow singular, special, and profoundly alone, or does it just mean that we’re looking for life in all the wrong places? As star-gazing scientists come closer to learning the truth, their insights are proving ever more crucial to understanding life’s intricate mysteries and possibilities right here on Earth.Science journalist Lee Billings explores the past and future of the "exoplanet boom" through in-depth reporting and interviews with the astronomers andplanetary scientists at its forefront. He recounts the stories behind their world-changing discoveries and captures the pivotal moments that drove them forward in their historic search for the first habitable planets beyond our solar system. Billings brings readers close to a wide range of fascinating characters, such as:FRANK DRAKE, a pioneer who has used the world’s greatest radio telescopes to conduct the first searches for extraterrestrial intelligence and to transmit a message to the stars so powerful that it briefly outshone our Sun.JIM KASTING, a mild-mannered former NASA scientist whose research into the Earth’s atmosphere and climate reveals the deepest foundations of life on our planet, foretells the end of life on Earth in the distant future, and guides the planet hunters in their search for alien life.SARA SEAGER, a visionary and iron-willed MIT professor who dreams of escaping the solar system and building the giant space telescopes required to discover and study life-bearing planets around hundreds of the Sun’s neighboring stars.Through these and other captivating tales, Billings traces the triumphs, tragedies, and betrayals of the extraordinary men and women seeking life among the stars. In spite of insufficient funding, clashing opinions, and the failings of some of our world’s most prominent and powerful scientific organizations, these planet hunters will not rest until they find the meaning of life in the infinite depths of space. Billings emphasizes that the heroic quest for other Earth-like planets is not only a scientific pursuit, but also a reflection of our own culture’s timeless hopes and fears.

    He spent six days orbiting the moon, including three days completely alone, the most isolated human in existence. During the return from the moon to earth he also conducted the first spacewalk in deep space, becoming the first human ever to see both the entire earth and moon simply by turning his head. The Apollo 15 flight capped an already-impressive career as an astronaut, including important work on the pioneering Apollo 9 and Apollo 12 missions, as well as the perilous flight of Apollo 13.Nine months after his return from the moon, Worden received a phone call telling him he was fired and ordering him out of his office by the end of the week. He refused to leave.What happened in those nine months, from being honored with parades and meetings with world leaders to being unceremoniously fired, has been a source of much speculation for four decades. Worden has never before told the full story around the dramatic events that shook NASA and ended his spaceflight career. Readers will learn them here for the first time, along with the exhilarating account of what it is like to journey to the moon and back. It's an unprecedentedly candid account of what it was like to be an Apollo astronaut, with all its glory but also its pitfalls.

    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.

    Pluto is entrenched in our cultural and emotional view of the cosmos, and Neil deGrasse Tyson, award-winning author and director of the Rose Center, is on a quest to discover why. He stood at the heart of the controversy over Pluto's demotion, and consequently Plutophiles have freely shared their opinions with him, including endless hate mail from third-graders. With his inimitable wit, Tyson delivers a minihistory of planets, describes the oversized characters of the people who study them, and recounts how America's favorite planet was ousted from the cosmic hub.

    They are found on the Moon, where fifty-six miles of car tracks lie nearly perfectly preserved, etched into the lunar landscape almost exactly as they were left nearly a half-century ago. The ends of these trails mark the farthest extremes to which mankind has ventured, the limits of a species that was born to wander.The tracks were left by crews of the last three manned missions to the Moon—Apollos 15, 16, and 17. Over the decades since, the achievements of these astronauts have dimmed in the shadow cast by the first Moon landing, Apollo 11. But as Earl Swift brilliantly uncovers, in so many ways the earlier missions were but a prelude for the final acts; for while Neil Armstrong and Buzz Aldrin trod a chunk of flat lunar plain smaller than a football field, the final three Apollos each commanded a mountainous area the size of Manhattan—traveling miles across the broken, desolate lunar surface, conducting experiments, and collecting more than a quarter-ton of prized geologic samples. Often treated as little more than historical footnotes, they were the true explorers of the Moon. And they succeeded for one very American reason: they drove.So-called “Moon cars” had been the stuff of science fiction since before the Wright brothers flew. But it was only after World War II that engineers and scientists took up the challenge of how to move astronauts and equipment across extraterrestrial landscapes. The result was the Lunar Roving Vehicle—a true engineering marvel that was developed piecemeal through the late 1950s and 1960s, deployed on the final three Apollo missions, and revolutionized the exploration of the moon.In this fast-moving exploration of the lunar rover and the scientific discoveries it enabled, Swift puts the reader alongside the men who dreamed of the rover, designed it, troubleshot its flaws, and drove it on the lunar surface. Finally shining a deserved spotlight on these overlooked yet crucial missions and the fascinating characters involved in them, Across the Airless Wilds is a celebration of human genius, perseverance, and daring.
