Lacking the ability to measure their longitude, sailors throughout the great ages of exploration had been literally lost at sea as soon as they lost sight of land. Thousands of lives, and the increasing fortunes of nations, hung on a resolution.The scientific establishment of Europe—from Galileo to Sir Issac Newton—had mapped the heavens in both hemispheres in its certain pursuit of a celestial answer. In stark contrast, one man, John Harrison, dared to imagine a mechanical solution—a clock that would keep precise time at sea, something no clock had ever been able to do on land. Longitude is a dramatic human story of an epic scientific quest and Harrison's forty-year obsession with building his perfect timekeeper, known today as the chronometer. Full of heroism and chicanery, it is also a fascinating brief history of astronomy, navigation, and clock-making, and opens a new window on our world.On its 10th anniversary, a gift edition of this classic book, with a forward by one of history's greatest explorers, and eight pages of color illustrations.

    Our Big Bang, our distant future, parallel worlds, the sub-atomic and intergalactic - none of them are what they seem. But there is a way to understand this immense strangeness - mathematics. Seeking an answer to the fundamental puzzle of why our universe seems so mathematical, Tegmark proposes a radical idea: that our physical world not only is described by mathematics, but that it is mathematics. This may offer answers to our deepest questions: How large is reality? What is everything made of? Why is our universe the way it is?Table of ContentsPreface 1 What Is Reality?

    A sensational disappearance that made headlines around the world. A quest for truth that leads to death, madness or disappearance for those who seek to solve it. The Lost City of Z is a blockbuster adventure narrative about what lies beneath the impenetrable jungle canopy of the Amazon.After stumbling upon a hidden trove of diaries, New Yorker writer David Grann set out to solve "the greatest exploration mystery of the 20th century": What happened to the British explorer Percy Fawcett & his quest for the Lost City of Z?In 1925, Fawcett ventured into the Amazon to find an ancient civilization, hoping to make one of the most important discoveries in history. For centuries Europeans believed the world's largest jungle concealed the glittering kingdom of El Dorado. Thousands had died looking for it, leaving many scientists convinced that the Amazon was truly inimical to humans. But Fawcett, whose daring expeditions inspired Conan Doyle's The Lost World, had spent years building his scientific case. Captivating the imagination of millions round the globe, Fawcett embarked with his 21-year-old son, determined to prove that this ancient civilisation--which he dubbed Z--existed. Then his expedition vanished. Fawcett's fate, & the tantalizing clues he left behind about Z, became an obsession for hundreds who followed him into the uncharted wilderness. For decades scientists & adventurers have searched for evidence of Fawcett's party & the lost City of Z. Countless have perished, been captured by tribes or gone mad. As Grann delved ever deeper into the mystery surrounding Fawcett's quest, & the greater mystery of what lies within the Amazon, he found himself, like the generations who preceded him, being irresistibly drawn into the jungle's green hell. His quest for the truth & discoveries about Fawcett's fate & Z form the heart of this complexly enthralling narrative.

      In the past few years, a handful of scientists have been in a race to explain a disturbing aspect of our universe: only 4 percent of it consists of the matter that makes up you, me, our books, and every planet, star, and galaxy. The rest—96 percent of the universe—is completely unknown.   Richard Panek tells the dramatic story of how scientists reached this conclusion, and what they’re doing to find this "dark" matter and an even more bizarre substance called dark energy. Based on in-depth, on-site reporting and hundreds of interviews—with everyone from Berkeley’s feisty Saul Perlmutter and Johns Hopkins’s meticulous Adam Riess to the quietly revolutionary Vera Rubin—the book offers an intimate portrait of the bitter rivalries and fruitful collaborations, the eureka moments and blind alleys, that have fueled their search, redefined science, and reinvented the universe.

    She moved from New York to San Francisco, where she landed at a big-data startup in the heart of the Silicon Valley bubble: a world of surreal extravagance, dubious success, and fresh-faced entrepreneurs hell-bent on domination, glory, and, of course, progress.Anna arrived amidst a massive cultural shift, as the tech industry rapidly transformed into a locus of wealth and power rivaling Wall Street. But amid the company ski vacations and in-office speakeasies, boyish camaraderie and ride-or-die corporate fealty, a new Silicon Valley began to emerge: one in far over its head, one that enriched itself at the expense of the idyllic future it claimed to be building.Part coming-age-story, part portrait of an already-bygone era, Anna Wiener’s memoir is a rare first-person glimpse into high-flying, reckless startup culture at a time of unchecked ambition, unregulated surveillance, wild fortune, and accelerating political power. With wit, candor, and heart, Anna deftly charts the tech industry’s shift from self-appointed world savior to democracy-endangering liability, alongside a personal narrative of aspiration, ambivalence, and disillusionment.Unsparing and incisive, Uncanny Valley is a cautionary tale, and a revelatory interrogation of a world reckoning with consequences its unwitting designers are only beginning to understand.

    Starting once again with fossils, he turns his gaze skyward, showing us how the entirety of the universe’s fourteen-billion-year history can be seen in our bodies. As he moves from our very molecular composition (a result of stellar events at the origin of our solar system) through the workings of our eyes, Shubin makes clear how the evolution of the cosmos has profoundly marked our own bodies. Fully illustrated with black and white drawings.

    With the Big Bang, it went from a state of unimaginable density to an all-encompassing cosmic fireball to a simmering fluid of matter and energy, laying down the seeds for everything from dark matter to black holes to one rocky planet orbiting a star near the edge of a spiral galaxy that happened to develop life. But what happens at the end of the story? In billions of years, humanity could still exist in some unrecognizable form, venturing out to distant space, finding new homes and building new civilizations. But the death of the universe is final. What might such a cataclysm look like? And what does it mean for us? Dr. Katie Mack has been contemplating these questions since she was eighteen, when her astronomy professor first informed her the universe could end at any moment, setting her on the path toward theoretical astrophysics. Now, with lively wit and humor, she unpacks them in The End of Everything, taking us on a mind-bending tour through each of the cosmos’ possible finales: the Big Crunch; the Heat Death; Vacuum Decay; the Big Rip; and the Bounce. In the tradition of Neil DeGrasse’s bestseller Astrophysics for People in a Hurry, Mack guides us through major concepts in quantum mechanics, cosmology, string theory, and much more, in a wildly fun, surprisingly upbeat ride to the farthest reaches of everything we know.

    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

    But it would take the world some time to believe what had happened: the age of flight had begun, with the first heavier-than-air, powered machine carrying a pilot.Who were these men and how was it that they achieved what they did?David McCullough, two-time winner of the Pulitzer Prize, tells the surprising, profoundly American story of Wilbur and Orville Wright.Far more than a couple of unschooled Dayton bicycle mechanics who happened to hit on success, they were men of exceptional courage and determination, and of far-ranging intellectual interests and ceaseless curiosity, much of which they attributed to their upbringing. The house they lived in had no electricity or indoor plumbing, but there were books aplenty, supplied mainly by their preacher father, and they never stopped reading.When they worked together, no problem seemed to be insurmountable. Wilbur was unquestionably a genius. Orville had such mechanical ingenuity as few had ever seen. That they had no more than a public high school education, little money and no contacts in high places, never stopped them in their mission to take to the air. Nothing did, not even the self-evident reality that every time they took off in one of their contrivances, they risked being killed.In this thrilling book, master historian David McCullough draws on the immense riches of the Wright Papers, including private diaries, notebooks, scrapbooks, and more than a thousand letters from private family correspondence to tell the human side of the Wright Brothers' story, including the little-known contributions of their sister, Katharine, without whom things might well have gone differently for them.

    Yuri Gagarin is one of the great heroes of the twentieth century, but the details of his life and the Russian space effort have been shrouded in secrecy: even the names of the engineers who worked with Gagarin were a mystery to the West for many years.Starman is the first book to tell the compelling story behind Gagarin's life and his audacious first flight into space aboard a converted nuclear weapon.He was once the most famous man in the world yet in his life, as in death, he was a man the world knew almost nothing about.

    In the stirring, highly anticipated first volume of his presidential memoirs, Barack Obama tells the story of his improbable odyssey from young man searching for his identity to leader of the free world, describing in strikingly personal detail both his political education and the landmark moments of the first term of his historic presidency—a time of dramatic transformation and turmoil.Obama takes readers on a compelling journey from his earliest political aspirations to the pivotal Iowa caucus victory that demonstrated the power of grassroots activism to the watershed night of November 4, 2008, when he was elected 44th president of the United States, becoming the first African American to hold the nation’s highest office.Reflecting on the presidency, he offers a unique and thoughtful exploration of both the awesome reach and the limits of presidential power, as well as singular insights into the dynamics of U.S. partisan politics and international diplomacy. Obama brings readers inside the Oval Office and the White House Situation Room, and to Moscow, Cairo, Beijing, and points beyond. We are privy to his thoughts as he assembles his cabinet, wrestles with a global financial crisis, takes the measure of Vladimir Putin, overcomes seemingly insurmountable odds to secure passage of the Affordable Care Act, clashes with generals about U.S. strategy in Afghanistan, tackles Wall Street reform, responds to the devastating Deepwater Horizon blowout, and authorizes Operation Neptune’s Spear, which leads to the death of Osama bin Laden.A Promised Land is extraordinarily intimate and introspective—the story of one man’s bet with history, the faith of a community organizer tested on the world stage. Obama is candid about the balancing act of running for office as a Black American, bearing the expectations of a generation buoyed by messages of “hope and change,” and meeting the moral challenges of high-stakes decision-making. He is frank about the forces that opposed him at home and abroad, open about how living in the White House affected his wife and daughters, and unafraid to reveal self-doubt and disappointment. Yet he never wavers from his belief that inside the great, ongoing American experiment, progress is always possible.This beautifully written and powerful book captures Barack Obama’s conviction that democracy is not a gift from on high but something founded on empathy and common understanding and built together, day by day.

    In this compelling memoir, his first wife, Jane Hawking, relates the inside story of their extraordinary marriage. As Stephen's academic renown soared, his body was collapsing under the assaults of a motor neuron disease. Jane's candid account of trying to balance his 24-hour care with the needs of their growing family reveals the inner strength of the author, while the self-evident character and achievements of her husband make for an incredible tale presented with unflinching honesty. Jane's candor is no less apparent when the marriage finally ends in a high-profile meltdown, with Stephen leaving Jane for one of his nurses and Jane marrying an old family friend. In this exceptionally open, moving, and often funny memoir, Jane Hawking confronts not only the acutely complicated and painful dilemmas of her first marriage, but also the relationship's fault lines exposed by the pervasive effects of fame and wealth. The result is a book about optimism, love, and change that will resonate with readers everywhere.

    G. Lord was becoming a teenager in Southern California and her mother was dying of cancer, Lord's father-an archetypal, remote, rocket engineer- disappeared into his work at the Jet Propulsion Laboratory in Pasadena, building the space probes of the Mariner Mars 69 mission. Thirty years later, Lord found herself reporting on the JPL, triggering childhood memories and a desire to revisit her past as a way of understanding the ethos of rocket science. Astro Turf is the brilliant result of her journey of discovery.Remembering her pain at her father's absence, yet intrigued by what he did, Lord captures him on the page as she recalls her own youthful, eccentric fascination with science and space exploration. Into her family's saga she weaves the story of the legendary JPL- examining the complexities of its cultural history, from its start in 1936 to the triumphant Mars landings in 2004. She illuminates its founder, Frank Malina, whose brilliance in rocketry was shadowed by a flirtation with communism, driving him from the country even as we welcomed Wernher von Braun and his Nazi colleagues. Lord's own love of science fiction becomes a lens through which she views a profound cultural shift in the male-dominated world of space. And in pursuing the cause of her father's absence she stumbles on a hidden guilt, understanding "the anguish his proud silence caused both him and me, and how rooted that silence was in the culture of engineering."As in her acclaimed book Forever Barbie, which demystified an icon of feminine culture, Lord brings her penetrating insight to bear on a bastion of American masculinity, opening our eyes in unexpected and memorable ways.

    Joshua Mezrich creates life from loss, transplanting organs from one body to another. In this intimate, profoundly moving work, he illuminates the extraordinary field of transplantation that enables this kind of miracle to happen every day.When Death Becomes Life is a thrilling look at how science advances on a grand scale to improve human lives. Mezrich examines more than one hundred years of remarkable medical breakthroughs, connecting this fascinating history with the inspiring and heartbreaking stories of his transplant patients. Combining gentle sensitivity with scientific clarity, Mezrich reflects on his calling as a doctor and introduces the modern pioneers who made transplantation a reality—maverick surgeons whose feats of imagination, bold vision, and daring risk taking generated techniques and practices that save millions of lives around the world.Mezrich takes us inside the operating room and unlocks the wondrous process of transplant surgery, a delicate, intense ballet requiring precise timing, breathtaking skill, and at times, creative improvisation. In illuminating this work, Mezrich touches the essence of existence and what it means to be alive. Most physicians fight death, but in transplantation, doctors take from death. Mezrich shares his gratitude and awe for the privilege of being part of this transformative exchange as the dead give their last breath of life to the living. After all, the donors are his patients, too.When Death Becomes Life also engages in fascinating ethical and philosophical debates: How much risk should a healthy person be allowed to take to save someone she loves? Should a patient suffering from alcoholism receive a healthy liver? What defines death, and what role did organ transplantation play in that definition? The human story behind the most exceptional medicine of our time, Mezrich’s riveting book is a beautiful, poignant reminder that a life lost can also offer the hope of a new beginning.

    Houbolt, an unsung hero of Apollo 11 and the man who showed NASA how to put America on the moon. Without John C. Houbolt, a junior engineer at NASA, Apollo 11 would never have made it to the moon. Top NASA engineers on the project, including Werner Von Braun, strongly advocated for a single, huge spacecraft to travel to the moon, land, and return to Earth. It's the scenario used in 1950s cartoons and horror movies about traveling to outer space. Houbolt had another idea: Lunar Orbit Rendezvous. LOR would link two spacecraft in orbit while the crafts were travelling at 17,000 miles per hour. His plan was ridiculed and considered unthinkable. But this junior engineer was irrepressible. He stood by his concept, fired off memos to executives, and argued that LOR was the only way to success. For the 50th anniversary of Apollo 11, hear the untold story of the man who helped fulfill Kennedy’s challenge to reach the moon and begin exploring the final frontier.
