One held that the entire universe was contained in the Milky Way galaxy. Their champion was the strong-willed astronomer Harlow Shapley. Another camp believed that the universe was so vast that the Milky Way was just one galaxy among billions—the view that would prevail, proven by the equally headstrong Edwin Hubble.Almost forgotten is the Harvard Observatory "computer"—a human number cruncher hired to calculate the positions and luminosities of stars in astronomical photographs—who found the key to the mystery. Radcliffe-educated Henrietta Swan Leavitt, fighting ill health and progressive deafness, stumbled upon a new law that allowed astronomers to use variable stars—those whose brightness rhythmically changes—as a cosmic yardstick. Miss Leavitt's Stars is both a masterly account of how we measure the universe and the moving story of a neglected genius

    Beginning with an obscure discovery in 1896, radioactivity led researchers on a quest for understanding that ultimately confronted the intersection of knowledge and mystery. Mysterious from the start, radioactivity attracted researchers who struggled to understand it. What caused certain atoms to give off invisible, penetrating rays? Where did the energy come from? These questions became increasingly pressing when researchers realized the process seemed to continue indefinitely, producing huge quantities of energy. Investigators found cases where radioactivity did change, forcing them to the startling conclusion that radioactive bodies were transmuting into other substances. Chemical elements were not immutable after all. Radioactivity produced traces of matter so minuscule and evanescent that researchers had to devise new techniques and instruments to investigate them. Scientists in many countries, but especially in laboratories in Paris, Manchester, and Vienna unraveled the details of radioactive transformations. They created a new science with specialized techniques, instruments, journals, and international conferences. Women entered the field in unprecedented numbers. Experiments led to revolutionary ideas about the atom and speculations about atomic energy. The excitement spilled over to the public, who expected marvels and miracles from radium, a scarce element discovered solely by its radioactivity. The new phenomenon enkindled the imagination and awakened ancient themes of literature and myth. Entrepreneurs created new industries, and physicians devised novel treatments for cancer. Radioactivity gave archaeologists methods for dating artifacts and meteorologists a new explanation for the air's conductivity. Their explorations revealed a mysterious radiation from space. Radioactivity profoundly changed science, politics, and culture. The field produced numerous Nobel Prize winners, yet radioactivity's talented researchers could not solve the mysteries underlying the new phenomenon. That was left to a new generation and a new way of thinking about reality. Radioactivity presents this fascinating history in a way that is both accessible and appealing to the general reader. Not merely a historical account, the book examines philosophical issues connected with radioactivity, and relates its topics to broader issues regarding the nature of science.

    "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.

    No cloistered don, this tall, married Englishman was a freethinking intellectual. A nudist, he was devoted to quirky folk dancing. In 1937, while working as a biochemist at Cambridge, he fell in love with a visiting Chinese student, with whom he began a lifelong affair. His mistress persuaded him to travel to her home country, where he embarked on a series of expeditions to the frontiers of the ancient empire. He searched for evidence to bolster a conviction that the Chinese were responsible for hundreds of humankind's most familiar innovations—including printing, the compass, explosives, suspension bridges, even toilet paper—often centuries before others. His journeys took him across war-torn China, consolidating his admiration for the Chinese. After the war, he determined to announce what he'd discovered & began writing Science & Civilization in China, describing the country's long history of invention & technology. By the time he died, he'd produced, almost single-handedly, 17 volumes, making him the greatest one-man encyclopedist ever. Epic & intimate, The Man Who Loved China tells the sweeping story of China thru Needham's life. Here's a tale of what makes men, nations & humankind great—related by one of the world's best storytellers.

    He was a celebrity during the height of America’s Gilded Age. In this book, you will read about his friendship with Mark Twain, his furious competition with his former employer Thomas Edison, his uneasy relationship with billionaire J.P. Morgan, and his rivalry with Albert Einstein. During his lifetime, Tesla revolutionized the field of electrical engineering with his most famous invention: the induction motor. But that wasn’t all he contributed to the world of technology. His coils, turbines, robotic boats, and mysterious “death ray” continue to beguile the imagination and inspire the inventors of the 21st century. But who was Tesla really? This book will take you from his early childhood in Croatia, where he experienced strange optical visions and “luminous phenomenon” that gave him near super-human powers of memory and visualization, to the “War of the Currents”, Thomas Edison’s bizarre campaign to ruin Tesla’s reputation. From trying to fight the Spanish American War with robots, to electrifying the skies of the Colorado desert, and to starting an earthquake in the middle of New York city, learn how Nikola Tesla shaped the world we live in today.

    In 1829, a wealthy English naturalist named James Smithson left his library, mineral collection, and entire fortune to "the United States of America, to found ... an establishment for the increase and diffusion of Knowledge among men" -- even though he had never visited the United States or known any Americans. In this fascinating book, Nina Burleigh pieces together the reclusive benefactor's life and painstaking scientific pursuits, and discloses how his bequest was nearly lost due to political infighting until several heroes, including former president John Quincy Adams, saw to it that Smithson's curious notion was realized in 1846. The result was the Smithsonian: a castle housing the United States' first and greatest cultural and scientific establishment, one that has since funded thousands of scientific and exploratory projects around the world and given the nation's capital an enduring cultural foundation.

    He was also a pilot, an author, an actor, and a rabid opponent of the Spiritualist movement. He was impatient of charlatans and imitators and loving to his family. He had an impressive ego. If any of these facts are new to you, then Houdini: A Life Worth Reading is the perfect primer on the man who was, by the end of his life, known only as Houdini. From his Nude Cell Escape (yes, that is exactly like it sounds) to his methodical debunking of mediums, Houdini orchestrated his talent, persona, and career with care, enthusiasm, and determination. With an easy-to-read biography, writings from Houdini himself, and quick-fact introductions to each chapter, Houdini: A Life Worth Reading will tell you what you want most to know about the King of Handcuffs, also known as Ehrich Weisz, also known as the great Houdini.

    In Ray, North Dakota, a young farm girl named Mary Sherman was attending high school. In an age when girls rarely dreamed of a career in science, Mary wanted to be a chemist. A decade later the dreams of these two disparate individuals would coalesce in ways neither could have imagined. World War II and the Cold War space race with the Russians changed the fates of both von Braun and Mary Sherman Morgan. When von Braun and other top engineers could not find a solution to the repeated failures that plagued the nascent U.S. rocket program, North American Aviation, where Sherman Morgan then worked, was given the challenge. Recognizing her talent for chemistry, company management turned the assignment over to young Mary. In the end, America succeeded in launching rockets into space, but only because of the joint efforts of the brilliant farm girl from North Dakota and the famous German scientist. While von Braun went on to become a high-profile figure in NASA's manned space flight, Mary Sherman Morgan and her contributions fell into obscurity--until now.

    Poe, The Other Einstein offers us a window into a brilliant, fascinating woman whose light was lost in Einstein's enormous shadow. It is the story of Einstein's wife, a brilliant physicist in her own right, whose contribution to the special theory of relativity is hotly debated and may have been inspired by her own profound and very personal insight.Mitza Maric has always been a little different from other girls. Most twenty-year-olds are wives by now, not studying physics at an elite Zurich university with only male students trying to outdo her clever calculations. But Mitza is smart enough to know that, for her, math is an easier path than marriage. And then fellow student Albert Einstein takes an interest in her, and the world turns sideways. Theirs becomes a partnership of the mind and of the heart, but there might not be room for more than one genius in a marriage.

    Kennedy’s tragic assassination.In those four years, Hill was by Mrs. Kennedy’s side for some of the happiest moments as well as the darkest. He was there for the birth of John, Jr. on November 25, 1960, as well as for the birth and sudden death of Patrick Bouvier Kennedy on August 8, 1963. Three and a half months later, the unthinkable happened. Forty-seven years after the assassination of President John F. Kennedy, the one vivid image that never leaves Clint Hill’s mind is that of President Kennedy’s head lying on Mrs. Kennedy’s lap in the back seat of the limousine, his eyes fixed, blood splattered all over the back of the car, Mrs. Kennedy, and Hill as well. Sprawled on the trunk of the car as it sped away from Dealey Plaza, Hill clung to the sides of the car, his feet wedged in so his body was as high as possible. Clint Hill jumped on the car too late to save the president, but all he knew after that first shot was that if more shots were coming, the bullets had to hit him instead of the First Lady. Mrs. Kennedy’s strength, class, and dignity over those tragic four days in November 1963 held the country together. This is the story, told for the first time, of the man who perhaps held her together.

    Now he gathers the best of his best, updated and expanded upon, to guide readers on a mind-bending tour of the far frontier, and how these advances are radically transforming our lives. From the ways science and technology are fundamentally altering our bodies and our world (the world’s first bionic soldier, the future of evolution) to those explosive collisions between science and culture (life extension and bioweapons), we’re crossing moral and ethical lines we’ve never faced before.As Kotler writes, “Life is tricky sport—and that's the emotional core of this story, the real reason we can’t put Pandora back in the box. When you strip everything else away, technology is nothing more than the promise of an easier tomorrow. It’s the promise of hope. And how do you stop hope?”Join Kotler in this fascinating exploration of our incredible next: a deep dive into those future technologies happening now—and what it means to be a part of this brave new world.

    Because the Wright brothers worked in secrecy, word of their first flights had not reached Europe when Santos-Dumont took to the skies in 1906. The dashing, impeccably dressed inventor entertained Paris with his airborne antics--barhopping in a little dirigible that he tied to lampposts, circling above crowds around the Eiffel Tower, and crashing into rooftops. A man celebrated, even pursued by the press in Paris, London, and New York, Santos-Dumont dined regularly with the Cartiers, the Rothschilds, and the Roosevelts. But beneath his lively public exterior, Santos-Dumont was a frenzied genius tortured by the weight of his own creation.Wings of Madness chronicles the science and history of early aviation and offers a fascinating glimpse into the mind of an extraordinary and tormented man, vividly depicting the sights and sounds of turn-of-the-century Paris. It is a book that will do for aviation what The Man Who Loved Only Numbers did for mathematics.

    Alexander von Humboldt (1769 – 1859) was an intrepid explorer and the most famous scientist of his age. In North America, his name still graces four counties, thirteen towns, a river, parks, bays, lakes, and mountains. His restless life was packed with adventure and discovery, whether he was climbing the highest volcanoes in the world or racing through anthrax-infected Siberia or translating his research into bestselling publications that changed science and thinking. Among Humboldt's most revolutionary ideas was a radical vision of nature, that it is a complex and interconnected global force that does not exist for the use of humankind alone. Now Andrea Wulf brings the man and his achievements back into focus: his daring expeditions and investigation of wild environments around the world and his discoveries of similarities between climate and vegetation zones on different continents. She also discusses his prediction of human-induced climate change, his remarkable ability to fashion poetic narrative out of scientific observation, and his relationships with iconic figures such as Simón Bolívar and Thomas Jefferson. Wulf examines how Humboldt's writings inspired other naturalists and poets such as Darwin, Wordsworth, and Goethe, and she makes the compelling case that it was Humboldt's influence that led John Muir to his ideas of natural preservation and that shaped Thoreau's Walden.With this brilliantly researched and compellingly written book, Andrea Wulf shows the myriad fundamental ways in which Humboldt created our understanding of the natural world, and she champions a renewed interest in this vital and lost player in environmental history and science.
