At the outset this group included the wives, sisters, and daughters of the resident astronomers, but soon the female corps included graduates of the new women's colleges--Vassar, Wellesley, and Smith. As photography transformed the practice of astronomy, the ladies turned from computation to studying the stars captured nightly on glass photographic plates.The "glass universe" of half a million plates that Harvard amassed over the ensuing decades--through the generous support of Mrs. Anna Palmer Draper, the widow of a pioneer in stellar photography--enabled the women to make extraordinary discoveries that attracted worldwide acclaim. They helped discern what stars were made of, divided the stars into meaningful categories for further research, and found a way to measure distances across space by starlight. Their ranks included Williamina Fleming, a Scottish woman originally hired as a maid who went on to identify ten novae and more than three hundred variable stars; Annie Jump Cannon, who designed a stellar classification system that was adopted by astronomers the world over and is still in use; and Dr. Cecilia Helena Payne, who in 1956 became the first ever woman professor of astronomy at Harvard--and Harvard's first female department chair.

    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.

    They unearthed a treasure trove of Cretaceous dinosaurs and mammals, including several new species, that has already helped to reshape our understanding of the dinosaur age. In Dinosaurs of the Flaming Cliffs, team leader Michael Novacek, Provost of Science of the American Museum of Natural History and Curator of Vertebrate Paleontology, re-creates the day-to-day drama of field exploration over the past six years in the Gobi and recounts his and his colleagues' historic discoveries, reported in front-page headlines across the world. In a remarkable narrative that interweaves expedition chapters with in-depth scientific discussions on the nature and importance of the fossil record, Novacek takes us on a journey that explores the very nature of scientific inquiry and dinosaur research.

    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.

    Yet his greatest accomplishments--the Louisiana Purchase, the First Barbary War, the Lewis and Clark expedition--almost all came in his first term in office. His second term saw a sharp reversal of fortunes, as catastrophe engulfed the nation and Jefferson slunk out of office, never to play a role in public affairs again. While always giving a great man his due, this new biography explores the darker side of Jefferson's political legacy, examining how the flaws in both his personality and ideology led the nation to the brink of war and dissolution. It tells how Jefferson tossed aside legal norms in his pursuit of rival judges and his own vice president, and how his 1807 Embargo Act devastated the national economy, heightened section divisions, and made a subsequent war with Great Britain all but inevitable. Only when we understand the damage that Jefferson did to America, as well as his many achievements, can we begin to grapple with the complex legacy of our nation's most complex president.

    But ambition quickly took wing. The house swelled to 225 rooms and became - until 2012 when it was topped by the home of a billionaire in Mumbai, India – the world’s largest residence ever built for a private citizen. Here’s the story of the house that Vanderbilt built - from the gardens by Frederick Law Olmsted to the John Singer Sargent portraits that adorn its walls.

    A twenty-eight year old — and not widely famous — Christopher Wren was giving a lecture on astronomy. As his audience listened to him speak, they decided that it would be a good idea to create a Society to promote the accumulation of useful knowledge.With that, the Royal Society was born. Since its birth, the Royal Society has pioneered scientific exploration and discovery. Isaac Newton, Charles Darwin, Albert Einstein, Robert Hooke, Robert Boyle, Joseph Banks, Humphry Davy, Isambard Kingdom Brunel, John Locke, Alexander Fleming — all were fellows.Bill Bryson’s favourite fellow was Reverend Thomas Bayes, a brilliant mathematician who devised Bayes’ theorem. Its complexity meant that it had little practical use in Bayes’ own lifetime, but today his theorem is used for weather forecasting, astrophysics and stock market analysis. A milestone in mathematical history, it only exists because the Royal Society decided to preserve it — just in case. The Royal Society continues to do today what it set out to do all those years ago. Its members have split the atom, discovered the double helix, the electron, the computer and the World Wide Web. Truly international in its outlook, it has created modern science.Seeing Further celebrates its momentous history and achievements, bringing together the very best of science writing. Filled with illustrations of treasures from the Society’s archives, this is a unique, ground-breaking and beautiful volume, and a suitable reflection of the immense achievements of science.

    Wilson 's mesmerizing evocation of his Southern childhood in The Naturalist and Anthill, Alex Harris approached the scientist about collaborating on a book about Wilson 's native world of Mobile, Alabama. Perceiving that Mobile was a city small enough to be captured through a lens yet old enough to have experienced a full epic cycle of tragedy and rebirth, the photographer and the naturalist joined forces to capture the rhythms of this storied Alabama Gulf region through a swirling tango of lyrical words and breathtaking images. With Wilson tracing his family 's history from the Civil War through the Depression when mule-driven wagons still clogged the roads to Mobile 's racial and environmental struggles to its cultural triumphs today, and with Harris stunningly capturing the mood of a radically transformed city that has adapted to the twenty-first century, the book becomes a universal story, one that tells us where we all come from and why we are here.

    Illustrating his text with maps, graphics, and photographs, David offers inside information about how the United States, allies and competitors, as well as key private corporations like Moon Express and Jeff Bezos's Blue Origin, plan to reach, inhabit, and even harvest the moon in the decades to come.Spurred on by the Google Lunar XPRIZE--$20 million for the first to get to the moon and send images home--the 21st-century space race back to the moon has become more urgent, and more timely, than ever. Accounts of these new strategies are set against past efforts, including stories never before told about the Apollo missions and Cold War plans for military surveillance and missile launches from the moon. Timely and fascinating, this book sheds new light on our constant lunar companion, offering reasons to gaze up and see it in a different way than ever before.

    Churchill, 1948: World War II was the defining event of our age—the climactic clash between liberty and tyranny. It led to revolutions, the demise of empires, a protracted Cold War, and religious strife still not ended. Yet Churchill maintained that it was all avoidable. Here is a transformative view of Churchill’s theories, prescriptions, actions, and the degree to which he pursued them in the decade before the war. It shows that he was both right and wrong: right that Hitler could have been stopped; wrong that he did all he could to stop him. It is based on what really happened—evidence that has been “hiding in public” for many years, thoroughly referenced in Churchill’s words and those of his contemporaries. Richard M. Langworth began his Churchill work in 1968 when he organized the Churchill Study Unit, which later became the Churchill Centre. He served as its president and board chairman and was editor of its journal Finest Hour from 1982 to 2014. In November 2014, he was appointed senior fellow for Hillsdale College’s Churchill Project. Mr. Langworth published the first American edition of Churchill’s India, is the author of A Connoisseur’s Guide to the Books of Sir Winston Churchill, and is the editor of Churchill by Himself, The Definitive Wit of Winston Churchill, The Patriot’s Churchill, All Will Be Well: Good Advice from Winston Churchill, and Churchill in His Own Words. His next book is Winston Churchill, Urban Myths and Reality. In 1998, Richard Langworth was appointed a Commander of the Most Excellent Order of the British Empire by HM The Queen “for services to Anglo-American understanding and the memory of Sir Winston Churchill.”

     This area was dangerous and many who had ventured there alone had never returned. But slowly over the course of this century settlers continued to push further west until regions such as West Virginia were populated with more and more adventurous young men and women. The settlement of these lands did not occur without difficulties and colonizers frequently came into conflict with the local Native American populations. Wills De Hass’s remarkable book History of the Early Settlement and Indian Wars of West Virginia is a fascinating history of how the lands of the west were first settled by white emigrants in the eighteenth century and how these settlers came into frequent strife with the Native American tribes who had previously lived there. Beginning with Columbus’ discovery of this great continent Wills De Hass charts the colonization of this expansive land. He records with brilliant detail the early encounters that Europeans had with the men and women that they found already living across the region and explains how various nations from across the Atlantic made their first tentative footholds on this newly discovered land. De Hass records how settlers were not only conflict with Native Americans but also with each other as this region descended into war, firstly during the French and Indian War and shortly afterwards during the American War of Independence. Particularly fascinating throughout the book are the biographical sketches of various well-known frontiersmen who were particularly influential in the Ohio Valley and northwestern Virginia. This book is perfect for anyone interested in the early settlement of western regions prior to 1795 and how this area was frequently in conflict as settlers attempted to assert their rights against the wishes of the Native American populations. Wills de Hass was a lecturer and writer on archaeological and historical subjects. His book History of the Early Settlement and Indian Wars of Western Virginia was first published in 1851 and De Hass passed away 1910.
