    He provides an extraordinary mediation upon the nature of place, time and our daily lives.

    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.

    A city of gas lamps, cobblestone streets, and horse-drawn carriages—and home to the controversial surgeon Dr. Spencer Black. The son of a grave robber, young Dr. Black studies at Philadelphia’s esteemed Academy of Medicine, where he develops an unconventional hypothesis: What if the world’s most celebrated mythological beasts—mermaids, minotaurs, and satyrs—were in fact the evolutionary ancestors of humankind?  The Resurrectionist offers two extraordinary books in one. The first is a fictional biography of Dr. Spencer Black, from a childhood spent exhuming corpses through his medical training, his travels with carnivals, and the mysterious disappearance at the end of his life. The second book is Black’s magnum opus: The Codex Extinct Animalia, a Gray’s Anatomy for mythological beasts—dragons, centaurs, Pegasus, Cerberus—all rendered in meticulously detailed anatomical illustrations. You need only look at these images to realize they are the work of a madman. The Resurrectionist tells his story.

    The effects of homeopathy don’t go away under rigorous scientific conditions. The laws of nature aren’t what they used to be. Thirty years on, no one has an explanation for a seemingly intelligent signal received from outer space. The US Department of Energy is re-examining cold fusion because the experimental evidence seems too solid to ignore. The placebo effect is put to work in medicine while doctors can’t agree whether it even exists.In an age when science is supposed to be king, scientists are beset by experimental results they simply can’t explain. But, if the past is anything to go by, these anomalies contain the seeds of future revolutions. While taking readers on an entertaining tour d’horizon of the strangest of scientific findings – involving everything from our lack of free will to Martian methane that offers new evidence of life on the planet – Michael Brooks argues that the things we don’t understand are the key to what we are about to discover.This mind-boggling but entirely accessible survey of the outer limits of human knowledge is based on a short article by Michael Brooks for New Scientist magazine. It became the sixth most circulated story on the internet in 2005, and provoked widespread comment and compliments (Google “13 things that do not make sense” to see).Michael Brooks has now dug deeply into those mysteries, with extraordinary results.

    McGregor, and many other Beatrix Potter characters remain in the hearts of millions. However, though Potter is a household name around the world, few know the woman behind the illustrations. Her personal life, including a romantic relationship with her publisher, Norman Warne, and her significant achievements outside of children's literature remain largely unknown. In Linda Lear's enchanting new biography, we get the life story of this incredible, funny, and independent woman. As one of the first female naturalists in the world, Potter brought the beauty and importance of nature back into the imagination at a time when plunder was more popular than preservation. Through her art she sought to encourage conservation and change the world. With never before seen illustrations and intimate detail, Lear goes beyond our perrenial fascination with Potter as a writer and illustrator of children's books, and delves deeply into the life of a most unusual and gifted woman--one whose art was timeless, and whose generosity left an indelible imprint on the countryside.

    Kay Connolly, once an actress, now a young English Intelligence officer, ships out for Belgium to locate the launch sites and neutralize the threat. But when rumors of a defector circulate through the German ranks, Graf becomes a suspect. Unknown to each other, Graf and Connolly find themselves on opposite sides of the hunt for the saboteur. Their twin stories play out against the background of the German missile campaign, one of the most epic and modern but least explored episodes of the Second World War. Their destinies are on a collision course.

    Deployed today to celebrate subjects as various as the grandeur of art, the beauty of the human form, and the universality of the human spirit, the drawing turns up just about everywhere: in books, on coffee cups, on corporate logos, even on spacecraft. It has, in short, become the world’s most famous cultural icon—and yet almost nobody knows about the epic intellectual journeys that led to its creation. In this modest drawing that would one day paper the world, da Vinci attempted nothing less than to calibrate the harmonies of the universe and understand the central role man played in the cosmos.Journalist and storyteller Toby Lester brings Vitruvian Man to life, resurrecting the ghost of an unknown Leonardo. Populated by a colorful cast of characters, including Brunelleschi of the famous Dome, Da Vinci’s Ghost opens up a surprising window onto the artist and philosopher himself and the tumultuous intellectual and cultural transformations he bridged. With sparkling prose and a rich variety of original illustrations, Lester captures the brief but momentous time in the history of western thought when the Middle Ages gave way to the Renaissance, art and science and philosophy converged as one, and all seemed to hold out the promise that a single human mind, if properly harnessed, could grasp the nature of everything.

    An account of the year Clara Parkes spent transforming a 676-pound bale of fleece into saleable yarn, and the people and vanishing industry she discovered along the way.

    Even today remembered primarily as the mentor and lover of Robert Mapplethorpe, the once infamous photographer, Wagstaff, in fact, had an incalculable—and largely overlooked—influence on the world of contemporary art and photography, and on the evolution of gay identity in the latter part of the twentieth century.  Born in New York City in 1921 into a notable family, Wagstaff followed an arc that was typical of a young man of his class. He attended both Hotchkiss and Yale, served in the navy, and would follow in step with his Ivy League classmates to the "gentleman's profession," as an ad executive on Madison Avenue. With his unmistakably good looks, he projected an aura of glamour and was cited by newspapers as one of the most eligible bachelors of the late 1940s. Such accounts proved deceiving, for Wagstaff was forced to live in the closet, his homosexuality only revealed to a small circle of friends. Increasingly uncomfortable with his career and this double life, he abandoned advertising, turned to the formal study of art history, and embarked on a radical personal transformation that was in perfect harmony with the tumultuous social, cultural, and sexual upheavals of the 1960s.Accordingly, Wagstaff became a curator, in 1961, at Hartford's Wadsworth Atheneum, where he mounted both "Black, White, and Gray"—the first museum show of minimal art—and the sculptor Tony Smith's first museum show, while lending his early support to artists Andy Warhol, Ray Johnson, and Richard Tuttle, among many others. Later, as a curator at the Detroit Institute of Arts, he brought the avant-garde to a regional museum, offending its more staid trustees in the process.After returning to New York City in 1972, the fifty-year-old Wagstaff met the twenty-five-year-old Queens-born Robert Mapplethorpe, then living with Patti Smith. What at first appeared to be a sexual dalliance became their now historic lifelong romance, in which Mapplethorpe would foster Wagstaff's own burgeoning interest in contemporary photography and Wagstaff would help secure Mapplethorpe's reputation in the art world. In spite of their profound class differences, the artistic union between the philanthropically inclined Wagstaff and the prodigiously talented Mapplethorpe would rival that of Stieglitz and O’Keefe, or Rivera and Kahlo, in their ability to help reshape contemporary art history.Positioning Wagstaff's personal life against the rise of photography as a major art form and the simultaneous formation of the gay rights movement, Philip Gefter's absorbing biography provides a searing portrait of New York just before and during the age of AIDS. The result is a definitive and memorable portrait of a man and an era.

    At the peak of Red Cloud’s powers the Sioux could claim control of one-fifth of the contiguous United States and the loyalty of thousands of fierce fighters. But the fog of history has left Red Cloud strangely obscured. Now, thanks to the rediscovery of a lost autobiography, and painstaking research by two award-winning authors, the story of our nation’s most powerful and successful Indian warrior can finally be told.

    But between conception and execution there was the vastness of space itself, to say nothing of monumental technological challenges. Homesteading Space, by two of Skylab’s own astronauts and a NASA journalist, tells the dramatic story of America’s first space station from beginning to fiery end.  Homesteading Space is much more than a story of technological and scientific success; it is also an absorbing, sometimes humorous, often inspiring account of the determined, hardworking individuals who shepherded the program through a near-disastrous launch, a heroic rescue, and an exhausting study of Comet Kohoutek, as well as the lab's ultimate descent into the Indian Ocean. Featuring the unpublished in-flight diary of astronaut Alan Bean, the book is replete with the personal recollections and experiences of the Skylab crew and those who worked with them in training, during the mission, and in bringing them safely home.

    Few episodes in the development of scientific theory show so clearly how the solution to a highly technical problem can alter our basic thought processes and attitudes. Understanding the processes which underlay the Revolution gives us a perspective, in this scientific age, from which to evaluate our own beliefs more intelligently. With a constant keen awareness of the inseparable mixture of its technical, philosophical, and humanistic elements, Thomas S. Kuhn displays the full scope of the Copernican Revolution as simultaneously an episode in the internal development of astronomy, a critical turning point in the evolution of scientific thought, and a crisis in Western man's concept of his relation to the universe and to God.The book begins with a description of the first scientific cosmology developed by the Greeks. Mr. Kuhn thus prepares the way for a continuing analysis of the relation between theory and observation and belief. He describes the many functions--astronomical, scientific, and nonscientific--of the Greek concept of the universe, concentrating especially on the religious implications. He then treats the intellectual, social, and economic developments which nurtured Copernicus' break with traditional astronomy. Although many of these developments, including scholastic criticism of Aristotle's theory of motion and the Renaissance revival of Neoplatonism, lie entirely outside of astronomy, they increased the flexibility of the astronomer's imagination. That new flexibility is apparent in the work of Copernicus, whose De Revolutionibus Orbium Coelestium (On the Revolutions of the Heavenly Spheres) is discussed in detail both for its own significance and as a representative scientific innovation.With a final analysis of Copernicus' life work--its reception and its contribution to a new scientific concept of the universe--Mr. Kuhn illuminates both the researches that finally made the heliocentric arrangement work, and the achievements in physics and metaphysics that made the planetary earth an integral part of Newtonian science. These are the developments that once again provided man with a coherent and self-consistent conception of the universe and of his own place in it.This is a book for any reader interested in the evolution of ideas and, in particular, in the curious interplay of hypothesis and experiment which is the essence of modern science. Says James Bryant Conant in his Foreword: "Professor Kuhn's handling of the subject merits attention, for...he points the way to the road which must be followed if science is to be assimilated into the culture of our times."

    They all expected to die.Murray radioed out "Mayday" as he attempted to fly down through gale-force winds into the rough water, hoping the plane didn't break apart when it hit the sea.Only a handful of ships could pick up the distress call so far from land. The closest was a Swiss freighter 13 hours away. Dozens of other ships and planes from nine countries abruptly changed course or scrambled from Canada, Iceland, Ireland, Scotland, and Cornwall, all racing to the rescue--but they would take hours, or days, to arrive.From the cockpit, the blackness of the Atlantic grew ever closer. Could Murray do what no pilot had ever done--"land" a commercial airliner at night in a violent sea without everyone dying? And if he did, would rescuers find any survivors before they drowned or died from hypothermia in the icy water?The fate of Flying Tiger 923 riveted the world. Bulletins interrupted radio and TV programs. Headlines shouted off newspapers from London to LA. Frantic family members overwhelmed telephone switchboards. President Kennedy took a break from the brewing crises in Cuba and Mississippi to ask for hourly updates.Tiger in the Sea is a gripping tale of triumph, tragedy, unparalleled airmanship, and incredibly brave people from all walks of life. The author has pieced together the story--long hidden because of murky Cold War politics--through exhaustive research and reconstructed a true and inspiring tribute to the virtues of outside-the-box-thinking, teamwork, and hope.Learn more at TigerintheSea.com
