From the very first attempts by the Greeks to grapple with the complexities of our known world to the latest application of infinity in physics, The Road to Reality carefully explores the movement of the smallest atomic particles and reaches into the vastness of intergalactic space. Here, Penrose examines the mathematical foundations of the physical universe, exposing the underlying beauty of physics and giving us one the most important works in modern science writing.

    This discovery dramatically reshaped how humans understood their place in the cosmos, and once and for all laid to rest the idea that the Milky Way galaxy was alone in the universe. Six years later, continuing research by Hubble and others forced Albert Einstein to renounce his own cosmic model and finally accept the astonishing fact that the universe was not immobile but instead expanding. The fascinating story of these interwoven discoveries includes battles of will, clever insights, and wrong turns made by the early investigators in this great twentieth-century pursuit. It is a story of science in the making that shows how these discoveries were not the work of a lone genius but the combined efforts of many talented scientists and researchers toiling away behind the scenes. The intriguing characters include Henrietta Leavitt, who discovered the means to measure the vast dimensions of the cosmos . . . Vesto Slipher, the first and unheralded discoverer of the universe’s expansion . . . Georges Lemaître, the Jesuit priest who correctly interpreted Einstein’s theories in relation to the universe . . . Milton Humason, who, with only an eighth-grade education, became a world-renowned expert on galaxy motions . . . and Harlow Shapley, Hubble’s nemesis, whose flawed vision of the universe delayed the discovery of its true nature and startling size for more than a decade.Here is a watershed moment in the history of astronomy, brought about by the exceptional combination of human curiosity, intelligence, and enterprise, and vividly told by acclaimed science writer Marcia Bartusiak.

    Dye's stories from inside Mission Control explain the mysteries of flying the Shuttle -- from the powerful fiery ascent to the majesty of on-orbit operations to the high-speed and critical re-entry and landing of a hundred-ton glider.The Space Shuttles flew 135 missions -- surviving initial test flights and the early days of deploying satellites as well as enabling the assembly and servicing of the International Space Station. Astronauts conducted space walks, captured satellites, and docked with the Mir Space Station, bringing space into our everyday life, from GPS to satellite TV. Putting readers in the shoes of Mission Control, the hub that made humanity's leap into a new frontier possible, Dye gives readers his own front-row seat on the missions that changed our world.

    A favorite of Tesla and SpaceX founder Elon Musk, listeners will want to tune into this "really good book on rocket[s]," available for the first time in audio. Ignition! is the story of the search for a rocket propellant which could be trusted to take man into space. This search was a hazardous enterprise carried out by rival labs who worked against the known laws of nature, with no guarantee of success or safety. Acclaimed scientist and sci-fi author John Drury Clark writes with irreverent and eyewitness immediacy about the development of the explosive fuels strong enough to negate the relentless restraints of gravity. The resulting volume is as much a memoir as a work of history, sharing a behind-the-scenes view of an enterprise that eventually took men to the moon, missiles to the planets, and satellites to outer space. A classic work in the history of science, listeners will want to get their hands on this influential classic, available for the first time in decades.

    But with the unexpected death of her husband, her life became an empty, lightless space. Suddenly she was the single mother of two young boys, a widow at forty, clinging to three crumpled pages of instructions her husband had written for things like grocery shopping--things he had done while she did pioneering work as a planetary scientist at MIT. She became painfully conscious of her Asperger's, which before losing her husband had felt more like background noise. She felt, for the first time, alone in the universe.In this probing, invigoratingly honest memoir, Seager tells the story of how, as she stumblingly navigated the world of grief, she also kept looking for other worlds. She continues to develop groundbreaking projects, such as the Starshade, a sunflower-shaped instrument that, when launched into space, unfurls itself so as to block planet-obscuring starlight, and she takes solace in the alien beauty of exoplanets. At the same time, she discovers what feels every bit as wondrous: other people, reaching out across the space of her grief. Among them are the Widows of Concord, a group of women offering consolation and advice; and her beloved sons, Max and Alex. Most unexpected of all, there is another kind of one-in-a-billion match with an amateur astronomer.Equally attuned to the wonders of deep space and human connection, The Smallest Lights in the Universe is its own light in the dark.

    And yet she is often confounded by the cases she describes in her column: unexpected collections of symptoms that she and other physicians struggle to diagnose.A twenty-eight-year-old man, vacationing in the Bahamas for his birthday, tries some barracuda for dinner. Hours later, he collapses on the dance floor with crippling stomach pains. A middle-aged woman returns to her doctor, after visiting two days earlier with a mild rash on the back of her hands. Now the rash has turned purple and has spread across her entire body in whiplike streaks. A young elephant trainer in a traveling circus, once head-butted by a rogue zebra, is suddenly beset with splitting headaches, as if someone were "slamming a door inside his head."In each of these cases, the path to diagnosis--and treatment--is winding, sometimes frustratingly unclear. Dr. Sanders shows how making the right diagnosis requires expertise, painstaking procedure, and sometimes a little luck. Intricate, gripping, and full of twists and turns, Diagnosis puts readers in the doctor's place. It lets them see what doctors see, feel the uncertainty they feel--and experience the thrill when the puzzle is finally solved.

    Their work has uncovered a number of the universe’s more surprising secrets, and many believe further wonders remain hidden within the theory’s tangle of equations, waiting to be exposed. In this sweeping narrative of science and culture, astrophysicist Pedro Ferreira brings general relativity to life through the story of the brilliant physicists, mathematicians, and astronomers who have taken up its challenge. For these scientists, the theory has been both a treasure trove and an enigma, fueling a century of intellectual struggle and triumph.. Einstein’s theory, which explains the relationships among gravity, space, and time, is possibly the most perfect intellectual achievement of modern physics, yet studying it has always been a controversial endeavor. Relativists were the target of persecution in Hitler’s Germany, hounded in Stalin’s Russia, and disdained in 1950s America. Even today, PhD students are warned that specializing in general relativity will make them unemployable. Despite these pitfalls, general relativity has flourished, delivering key insights into our understanding of the origin of time and the evolution of all the stars and galaxies in the cosmos. Its adherents have revealed what lies at the farthest reaches of the universe, shed light on the smallest scales of existence, and explained how the fabric of reality emerges. Dark matter, dark energy, black holes, and string theory are all progeny of Einstein’s theory. We are in the midst of a momentous transformation in modern physics. As scientists look farther and more clearly into space than ever before, The Perfect Theory reveals the greater relevance of general relativity, showing us where it started, where it has led, and where it can still take us.

    Our stories are marbled into their marrow.Drawing upon her years of research and a wealth of remarkable experience, the world-renowned forensic anthropologist Professor Dame Sue Black takes us on a journey of revelation. From skull to feet, via the face, spine, chest, arms, hands, pelvis and legs, she shows that each part of us has a tale to tell. What we eat, where we go, everything we do leaves a trace, a message that waits patiently for months, years, sometimes centuries, until a forensic anthropologist is called upon to decipher it.Some of this information is easily understood, some holds its secrets tight and needs scientific cajoling to be released. But by carefully piecing together the evidence, the facts of a life can be rebuilt. Limb by limb, case by case – some criminal, some historical, some unaccountably bizarre – Sue Black reconstructs with intimate sensitivity and compassion the hidden stories in what we leave behind.

    She remembers her tin-roofed house tucked away in a vast forest paradise; the sparkling creeks, with their frogs and crawdads; the sweet blackberries growing along the road to her granny’s; and her abusive father, an underemployed alcoholic whose untethered rage and violence against Bobi and her mother were frighteningly typical of a community marginalized, desperate, and ignored. Bobi’s rule of survival: always be vigilant but endure it silently.Slipping away from home, Bobi went to college and got a white-collar job. Mistrusted by her family for her progress and condescended to by peers for her accent and her history, she was followed by the markers of her class. Though she carried her childhood self everywhere, Bobi also finally found her voice.An elegiac account of survival despite being born poor, female, and cloistered, Bobi’s testament is one of hope for all vulnerable populations, particularly women and girls caught in the cycle of poverty and abuse. On a continual path to worth, autonomy, and reinvention, Conn proves here that “the storyteller is the one with power.”

    It is a one-ton robot with two brains, seventeen cameras, six wheels, nuclear power, and a laser beam on its head. No one human understands how all of its systems and instruments work. This essential reference to the Curiosity mission explains the engineering behind every system on the rover, from its rocket-powered jetpack to its radioisotope thermoelectric generator to its fiendishly complex sample handling system. Its lavishly illustrated text explains how all the instruments work -- its cameras, spectrometers, sample-cooking oven, and weather station -- and describes the instruments' abilities and limitations. It tells you how the systems have functioned on Mars, and how scientists and engineers have worked around problems developed on a faraway planet: holey wheels and broken focus lasers. And it explains the grueling mission operations schedule that keeps the rover working day in and day out.

    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.

    Kennedy astonished the world on May 25, 1961, when he announced to Congress that the United States should land a man on the Moon by 1970. No group was more surprised than the scientists and engineers at NASA, who suddenly had less than a decade to invent space travel. When Kennedy announced that goal, no one knew how to navigate to the Moon. No one knew how to build a rocket big enough to reach the Moon, or how to build a computer small enough (and powerful enough) to fly a spaceship there. No one knew what the surface of the Moon was like, or what astronauts could eat as they flew there. On the day of Kennedy’s historic speech, America had a total of fifteen minutes of spaceflight experience—with just five of those minutes outside the atmosphere. Russian dogs had more time in space than U.S. astronauts. Over the next decade, more than 400,000 scientists, engineers, and factory workers would send 24 astronauts to the Moon. Each hour of space flight would require one million hours of work back on Earth to get America to the Moon on July 20, 1969. More than fifty years later, One Giant Leap is the sweeping, definitive behind-the-scenes account of the furious race to complete one of mankind’s greatest achievements. It’s a story filled with surprises—from the item the astronauts almost forgot to take with them (the American flag), to the extraordinary impact Apollo would have back on Earth, and on the way we live today. Charles Fishman introduces readers to the men and women who had to solve 10,000 problems before astronauts could reach the Moon. From the research labs of MIT, where the eccentric and legendary pioneer Charles Draper created the tools to fly the Apollo spaceships, to the factories where dozens of women sewed spacesuits, parachutes, and even computer hardware by hand, Fishman captures the exceptional feats of these ordinary Americans. One Giant Leap is the captivating story of men and women charged with changing the world as we knew it—their leaders, their triumphs, their near disasters, all of which led to arguably the greatest success story, and the greatest adventure story, of the twentieth century.

    Frizzle were a physics student of Stephen Hawking, she might have written THE UNIVERSE IN YOUR HAND, a wild tour through the reaches of time and space, from the interior of a proton to the Big Bang to the rough suburbs of a black hole. It's friendly, excitable, erudite, and cosmic."—Jordan Ellenberg, New York Times besteselling author of How Not To Be WrongQuantum physics, black holes, string theory, the Big Bang, dark matter, dark energy, parallel universes: even if we are interested in these fundamental concepts of our world, their language is the language of math. Which means that despite our best intentions of finally grasping, say, Einstein's Theory of General Relativity, most of us are quickly brought up short by a snarl of nasty equations or an incomprehensible graph.Christophe Galfard's mission in life is to spread modern scientific ideas to the general public in entertaining ways. Using his considerable skills as a brilliant theoretical physicist and successful young adult author, The Universe in Your Hand employs the immediacy of simple, direct language to show us, not explain to us, the theories that underpin everything we know about our universe. To understand what happens to a dying star, we are asked to picture ourselves floating in space in front of it. To get acquainted with the quantum world, we are shrunk to the size of an atom and then taken on a journey. Employing everyday similes and metaphors, addressing the reader directly, and writing stories rather than equations renders these astoundingly complex ideas in an immediate and visceral way.Utterly captivating and entirely unique, The Universe in Your Hand will find its place among other classics in the field.

    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.

    But if we are supposedly evolution’s greatest creation, why do we have such bad knees? Why do we catch head colds so often—two hundred times more often than a dog does? How come our wrists have so many useless bones? Why is the vast majority of our genetic code pointless? And are we really supposed to swallow and breathe through the same narrow tube? Surely there’s been some kind of mistake. As professor of biology Nathan H. Lents explains in Human Errors, our evolutionary history is nothing if not a litany of mistakes, each more entertaining and enlightening than the last. The human body is one big pile of compromises. But that is also a testament to our greatness: as Lents shows, humans have so many design flaws precisely because we are very, very good at getting around them.   A rollicking, deeply informative tour of humans’ four billion year long evolutionary saga, Human Errors both celebrates our imperfections and offers an unconventional accounting of the cost of our success.
