It's ever-present. Without it, you would die in minutes. And it has an epic story to tell.In Caesar's Last Breath, New York Times bestselling author Sam Kean takes us on a journey through the periodic table, around the globe, and across time to tell the story of the air we breathe, which, it turns out, is also the story of earth and our existence on it.With every breath, you literally inhale the history of the world. On the ides of March, 44 BC, Julius Caesar died of stab wounds on the Senate floor, but the story of his last breath is still unfolding; in fact, you're probably inhaling some of it now. Of the sextillions of molecules entering or leaving your lungs at this moment, some might well bear traces of Cleopatra's perfumes, German mustard gas, particles exhaled by dinosaurs or emitted by atomic bombs, even remnants of stardust from the universe's creation.Tracing the origins and ingredients of our atmosphere, Kean reveals how the alchemy of air reshaped our continents, steered human progress, powered revolutions, and continues to influence everything we do. Along the way, we'll swim with radioactive pigs, witness the most important chemical reactions humans have discovered, and join the crowd at the Moulin Rouge for some of the crudest performance art of all time. Lively, witty, and filled with the astounding science of ordinary life, Caesar's Last Breath illuminates the science stories swirling around us every second.

    With his trademark clarity and humor, Holt probes the mysteries of quantum mechanics, the quest for the foundations of mathematics, and the nature of logic and truth. Along the way, he offers intimate biographical sketches of celebrated and neglected thinkers, from the physicist Emmy Noether to the computing pioneer Alan Turing and the discoverer of fractals, Benoit Mandelbrot. Holt offers a painless and playful introduction to many of our most beautiful but least understood ideas, from Einsteinian relativity to string theory, and also invites us to consider why the greatest logician of the twentieth century believed the U.S. Constitution contained a terrible contradiction--and whether the universe truly has a future.

    Augustine equate nothingness with the Devil? What tortuous means did 17th-century scientists employ in their attempts to create a vacuum? And why do contemporary quantum physicists believe that the void is actually seething with subatomic activity? You’ll find the answers in this dizzyingly erudite and elegantly explained book by the English cosmologist John D. Barrow.Ranging through mathematics, theology, philosophy, literature, particle physics, and cosmology, The Book of Nothing explores the enduring hold that vacuity has exercised on the human imagination. Combining high-wire speculation with a wealth of reference that takes in Freddy Mercury and Shakespeare alongside Isaac Newton, Albert Einstein, and Stephen Hawking, the result is a fascinating excursion to the vanishing point of our knowledge.

    Fifty years ago, a few Americans became the first to do the reverse--and shared with Earth-bound audiences the view of their own planet hanging in the sky instead.Recently, the connection has been discovered to be even closer: a fragment of the Earth's surface was found embedded in a rock brought back from the Moon. And astronauts are preparing to return to the surface of the Moon after a half-century hiatus--this time to the dark side.Oliver Morton explores how the ways we have looked at the Moon have shaped our perceptions of the Earth: from the controversies of early astronomers such as van Eyck and Galileo, to the Cold War space race, to the potential use of the Moon as a stepping stone for further space exploration.Advanced technologies, new ambitions, and old dreams mean that men, women, and robots now seem certain to return to the Moon. For some, it is a future on which humankind has turned its back for too long. For others, an adventure yet to begin.

    It is so important that it provides the fundamental underpinning of all modern sciences. Without it, we'd have no nuclear power or nuclear bombs, no lasers, no TV, no computers, no science of molecular biology, no understanding of DNA, no genetic engineering—at all. John Gribbin tells the complete story of quantum mechanics, a truth far stranger than any fiction. He takes us step-by-step into an ever more bizarre and fascinating place—requiring only that we approach it with an open mind. He introduces the scientists who developed quantum theory. He investigates the atom, radiation, time travel, the birth of the universe, superconductors and life itself. And in a world full of its own delights, mysteries and surprises, he searches for Schrödinger's Cat—a search for quantum reality—as he brings every reader to a clear understanding of the most important area of scientific study today—quantum physics.

    Coated in red dust, the terrain is bewilderingly empty. And yet multiple spacecraft are circling Mars, sweeping over Terra Sabaea, Syrtis Major, the dunes of Elysium, and Mare Sirenum—on the brink, perhaps, of a staggering find, one that would inspire humankind as much as any discovery in the history of modern science.In this beautifully observed, deeply personal book, Georgetown scientist Sarah Stewart Johnson tells the story of how she and other researchers have scoured Mars for signs of life, transforming the planet from a distant point of light into a world of its own.Johnson’s fascination with Mars began as a child in Kentucky, turning over rocks with her father and looking at planets in the night sky. She now conducts fieldwork in some of Earth’s most hostile environments, such as the Dry Valleys of Antarctica and the salt flats of Western Australia, developing methods for detecting life on other worlds. Here, with poetic precision, she interlaces her own personal journey—as a female scientist and a mother—with tales of other seekers, from Percival Lowell, who was convinced that a utopian society existed on Mars, to Audouin Dollfus, who tried to carry out astronomical observations from a stratospheric balloon. In the process, she shows how the story of Mars is also a story about Earth: This other world has been our mirror, our foil, a telltale reflection of our own anxieties and yearnings.Empathetic and evocative, The Sirens of Mars offers an unlikely natural history of a place where no human has ever set foot, while providing a vivid portrait of our quest to defy our isolation in the cosmos.

    Sutter emphasizes how amazing it is that we are part of such a huge, complex, and mysterious place. Through metaphors and uncomplicated language, Sutter breathes life into the science of astrophysics, unveiling how particles, forces, and fields interplay to create the greatest of cosmic dramas. Touched with the author's characteristic breezy, conversational style--which has made him a breakout hit on venues such as The Weather Channel, the Science Channel, and his own popular Ask a Spaceman! podcast--he conveys the fun and wonder of delving deeply into the physical processes of the natural universe. He weaves together the past and future histories of our universe with grounded descriptions of essential modern-day physics as well as speculations based on the latest research in cosmology. Topics include our place in the Milky Way galaxy; the cosmic web--a vast web-like pattern in which galaxies are arranged; the origins of our universe in the big bang; the mysteries of dark matter and dark energy; how science has dramatically changed our relationship to the cosmos; conjectures about the future of reality as we know it; and more.For anyone who has ever stared at the starry night sky and wondered how we humans on Earth fit into the big picture, this book is an essential roadmap.

    Dave Williams, one of Canada’s most accomplished astronauts.I had dreamt about becoming an astronaut from the time I watched Alan Shepard launch on the first American sub-orbital flight on May 5, 1961. Eleven days before my seventh birthday, I committed to a new goal: one day, I would fly in outer space. Dr. Dave has led the sort of life that most people only dream of. He has set records for spacewalking. He has lived undersea for weeks at a time. He has saved lives as an emergency doctor, launched into the stratosphere twice, and performed surgery in zero gravity. But if you ask him how he became so accomplished, he’ll say: “I’m just a curious kid from Saskatchewan.” Curious indeed. Dr. Dave never lost his desire to explore nor his fascination with the world. Whether he was exploring the woods behind his childhood home or floating in space at the end of the Canadarm, Dave tried to see every moment of his life as filled with beauty and meaning. He learned to scuba dive at only twelve years old, became a doctor despite academic struggles as an undergraduate, and overcame stiff odds and fierce competition to join the ranks of the astronauts he had idolized as a child. There were setbacks and challenges along the way—the loss of friends in the Columbia disaster, a cancer diagnosis that nearly prevented him from returning to space—but through it all, Dave never lost sight of his goal. And when he finally had the chance to fly among the stars, he came to realize that although the destination can be spectacular, it’s the journey that truly matters. In Defying Limits, Dave shares the events that have defined his life, showing us that whether we’re gravity-defying astronauts or earth-bound terrestrials, we can all live an infinite, fulfilled life by relishing the value and importance of each moment. The greatest fear that we all face is not the fear of dying, but the fear of never having lived. Each of us is greater than we believe. And, together, we can exceed our limits to soar farther and higher than we ever imagined.

    Johannes Kepler, who discovered the three basic laws of planetary motion, was persecuted for his support of the Copernican system. After a neighbour accused his mother of witchcraft, Kepler quit his post as the Imperial mathematician to defend her.James Connor tells Kepler's story as a pilgrimage, a spiritual journey into the modern world through war and disease and terrible injustice, a journey reflected in the evolution of Kepler's geometrical model of the cosmos into a musical model, harmony into greater harmony. The leitmotif of the witch trial adds a third dimension to Kepler's biography by setting his personal life within his own times. The acts of this trial, including Kepler's letters and the accounts of the witnesses, although published in their original German dialects, had never before been translated into English. Echoing some of Dava Sobel's work for Galileo's Daughter, Connor has translated the witch trial documents into English. With a great respect for the history of these times and the life of this man, Connor's accessible story illuminates the life of Kepler, the man of science, but also Kepler, a man of uncommon faith and vision.

    It enables us to understand the structure and evolution of planetary systems, stars, galaxies, interstellar gas, and the cosmos as a whole.In this Very Short Introduction, the leading astrophysicist James Binney shows how the field of astrophysics has expanded rapidly in the past century, with vast quantities of data gathered by telescopes exploiting all parts of the electromagnetic spectrum, combined with the rapid advance of computing power, which has allowed increasingly effective mathematical modelling. He illustrates how the application of fundamental principles of physics - the consideration of energy and mass, and momentum - and the two pillars of relativity and quantum mechanics, has provided insights into phenomena ranging from rapidly spinning millisecond pulsars to the collision of giant spiral galaxies. This is a clear, rigorous introduction to astrophysics for those keen to cut their teeth on a conceptual treatment involving some mathematics.ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable

    Not until the nineteenth century would three men, armed with the best telescopes of their age, race to conquer this astronomical Everest. Parallax tells the fast-moving story of their contest, which ended in a dead heat. Against a sweeping backdrop filled with kidnappings, dramatic rescue, swordplay, madness, and bitter rivalry, Alan W. Hirshfeld brings to life the heroes -- and heroines -- of this remarkable chapter in history. Characters include the destitute boy plucked from a collapsed building who grew up to become the world's greatest telescope maker; the hot-tempered Dane whose nose was lopped off in a duel over mathematics; a merchant's apprentice forced to choose between the lure of money and his passion for astronomy; and the musician who astounded the world by discovering a new planet from his own backyard.Generously illustrated with period engravings and paintings, Parallax is an unforgettable ride through time and space.

    All three astronauts were experienced pilots and had dreams of one day walking on the moon, but little did they know, nor did anyone else, that once they entered the spacecraft that cold winter day they would never leave it alive. The Apollo program would be perilously close to failure before it ever got off the ground. But rather than dooming the space program, this tragedy caused the spacecraft to be completely overhauled, creating a stellar flying machine to achieve the program’s primary goal: putting man on the moon. Apollo 1 is a candid portrayal of the astronauts, the disaster that killed them, and its aftermath. In it, readers will learn: How the Apollo 1 spacecraft was doomed from the start, with miles of uninsulated wiring and tons of flammable materials in a pure oxygen atmosphere, along with a hatch that wouldn’t open How, due to political pressure, the government contract to build the Apollo 1 craft went to a bidder with an inferior plan How public opinion polls were beginning to turn against the space control before the tragedy and got much worse after Apollo 1 is about America fulfilling its destiny of man setting foot on the moon. It’s also about the three American heroes who lost their lives in the tragedy, but whose lives were not lost in vain.

    What would happen to his life, his presidency, his country, his world?Now he presents his most compelling narrative of all about the historical event that has riveted us for fifty years. What if Kennedy were not killed that fateful day? What would the 1964 campaign have looked like? Would changes have been made to the ticket? How would Kennedy, in his second term, have approached Vietnam, civil rights, the Cold War? With Hoover as an enemy, would his indiscreet private life finally have become public? Would his health issues have become so severe as to literally cripple his presidency? And what small turns of fate in the days and years before Dallas might have kept him from ever reaching the White House in the first place?As with Then Everything Changed, the answers Greenfield provides and the scenarios he develops are startlingly realistic, rich in detail, shocking in their projections, but always deeply, remarkably plausible. It is a tour de force of American political history.

    

    Probably no one felt more disappointment and regret than Allan McDonald, who had warned us not to launch that day. His story tells of loss, grief, and the eventual rebuilding and recovery."--Robert "Hoot" Gibson, former Space Shuttle pilot and commander   "A major contribution to a difficult episode in the history of human spaceflight."--Roger D. Launius, Division of Space History, Smithsonian Institution   “McDonald tells the heartbreaking tale of how he saw his words of warning ignored, and the fateful consequences of that decision.”--Donald C. Elder III, Eastern New Mexico University   On a cold January morning in 1986, NASA launched the Space Shuttle Challenger, despite warnings against doing so by many individuals, including Allan McDonald. The fiery destruction of Challenger on live television moments after launch remains an indelible image in the nation’s collective memory.   In Truth, Lies, and O-Rings, McDonald, a skilled engineer and executive, relives the tragedy from where he stood at Launch Control Center.  As he fought to draw attention to the real reasons behind the disaster, he was the only one targeted for retribution by both NASA and his employer, Morton Thiokol, Inc., makers of the shuttle’s solid rocket boosters. In this whistle-blowing yet rigorous and fair-minded book, McDonald, with the assistance of internationally distinguished aerospace historian James R. Hansen, addresses all of the factors that led to the accident, some of which were never included in NASA’s Failure Team report submitted to the Presidential Commission.  Truth, Lies, and O-Rings is the first look at the Challenger tragedy and its aftermath from someone who was on the inside, recognized the potential disaster, and tried to prevent it. It also addresses the early warnings of very severe debris issues from the first two post-Challenger flights, which ultimately resulted in the loss of Columbia some fifteen years later.
