Weaving together the cosmos' history and our own in an expanding intellectual adventure story, Dark Matter and the Dinosaurs takes us from the mysteries of dark matter and our cosmic environment to the conditions for life on Earth.Sixty-six million years ago, an object the size of a city descended from space to crash into Earth, creating a cataclysm that killed off the dinosaurs, along with three-quarters of the other species on the planet. What was its origin? Randall proposes it was a comet that was dislodged from its orbit as the Solar System passed through a disk of dark matter that is embedded in the plane of the Milky Way. Her research challenges the usual assumptions about the simple nature of dark matter and demonstrates how scientists formulate and establish new ideas. In a sense, it might have been dark matter that killed the dinosaurs.With her unique and wide-ranging perspective, Randall connects dark matter to the history of the world in the broadest terms. Bringing in pop culture and social and political viewpoints, she shares with us the latest findings—established and speculative—regarding dark matter, the cosmos, the galaxy, asteroids, comets, and impacts, as well as life's development and extinctions. Randall makes clear how connected the planet is to the makeup of the Universe, but also how fragile our place in the Universe, which evolved over billions of years, might be.In this brilliant and fresh exploration of our cosmic environment, Professor Randall explains the underlying science of our world in the breathtaking tale of a Universe in which the small and the large, the visible and the hidden are intimately related. Dark Matter and the Dinosaurs illuminates the deep relationships that are critical to our world as well as the astonishing beauty of the structures and connections that surround us. It's impossible to read this book and look at either Earth or sky again in the same way.

    However, their impact has not been limited to debates about geology and evolution: attempts to explain their existence has shaken religion at its very roots, and they have remained a subject of ceaseless fascination for people of all ages and backgrounds. In this readable and wide-ranging book, Keith Thomson provides a remarkably all-encompassing explanation of fossils as a phenomenon. How did Darwin use fossils to support his theory of evolution? What are living fossils? What fossils will we leave behind for future generations to examine? Beyond the scientific aspects, Thomson highlights the impact of fossils on philosophy and mythology, our concept of time, and today's popular culture. From the black market to the Piltdown Man, and from mythological dragons to living dinosaurs, fossils hold a permanent place in the popular imagination.

    Si todos debemos movernos para sobrevivir, vale la pena preguntarse: ¿qué factores de nuestro entorno nos impulsan a movernos y cuáles, por el contrario, nos detienen? ¿Por qué algunas personas tienen la oportunidad de moverse hacia donde quieren y otras no? ¿Por qué ciertas sociedades evolucionan y otras no? Para responder a estas interrogantes, los autores del libro estudiaron los códigos culturales y el comportamiento Bio-Lógico de 71 países para desarrollar un índice de que permite medir la movilidad social dentro de estas sociedades.Andrés Roemer y Clotaire Rapaille señalan que las culturas más exitosas son aquellas que han sabido preservar los mejores aspectos de su tradición, al mismo tiempo que han estado dispuestas a innovar y buscar nuevos horizontes. Se trata de sociedades abiertas al cambio y sin temor al statu quo. Otra clave del éxito evolutivo de las sociedades es el equilibrio entre el aspecto biológico (determinado por cuatro factores: supervivencia, sexo, seguridad y superación) y el aspecto cultural. El reto, concluyen los autores, es aprender a armonizar nuestros instintos (nuestro cerebro reptiliano) con nuestras emociones (nuestro cerebro límbico) y nuestra lógica (el neocórtex).ENGLISH DESCRIPTION If we all know we must move to survive, shouldn’t we ask ourselves which factors in our environment propel us and which halt us? Why do certain societies evolve while others don’t? In this book, Andrés Roemer and Clotaire Rapaille point out that the most successful cultures are those that are not afraid of the status quo: they have learned to preserve the best qualities of their traditions while being open to innovation and to uncovering new horizons. Another key to the success of these societies is the equilibrium between biological and the cultural aspects. The challenge is to harmonize our instincts, our emotions, and our logic.

    But Max Leonard, himself an accomplished amateur cyclist, does not forget the pain, the glory, the sweat, and the tears that go into these grueling climbs.  After all, cycling up a mountain is hard.  So hard that, to many, it can seem absurd. But for others, climbing a mountain gracefully (and beating your competitors up the slope) represents the pinnacle of cycling achievement. It is where legends are forged.Many books tell you where the mountains are, or how long and how high. None of them ask why. Why are mountain ranges professional cycling’s Coliseum? Why do amateurs also make pilgrimages to these high, remote roads? Why are the roads even there in the first place to lure us on to these obsession inducing climbs?   Just why are mountains so enthralling? “This is real cycling, where the glory is and where dreams come true,” according to Bradley Wiggins. Mountains are where cycling's greatest heroes have made their names. Every amateur rider wishes they could climb better, too.  Are all these people addicted to the pain? To the achievement? Or to the allure of the peaks? Some spend their weekends and holidays cycling up mountains from start to finish. But how does a rider push themselves beyond their limits to get up a 10% gradient on pedal power alone? What is happening when they do?A Higher Calling explores the central place of mountains in the folklore of road cycling. Blending adventure and travel writing with the rich narrative of racing, Max Leonard takes the reader from the battles that created the Alpine roads to the shepherds tending their flocks on the peaks, and to a Grand Tour climax on the “highest road in Europe.” And he tells stories of courage and sacrifice, war and love, obsession and even elephants, along the way.

    Yet, while common, oak woodlands are anything but ordinary. In a book rich in illustration and suffused with wonder, author Kate Marianchild combines extensive research and years of personal experience to explore some of the marvelous plants and animals that the oak woodlands nurture. Acorn woodpeckers unite in marriages of up to ten mates and raise their young cooperatively. Ground squirrels roll in rattlesnake skins to hide their scent from hungry snakes. Manzanita's rust-colored, paper-thin bark peels away in time for the summer solstice, exposing sinuous contours that are cool to the touch even on the hottest day. Conveying up-to-the-minute scientific findings with a storyteller's skill, Marianchild introduces us to a host of remarkable creatures in a world close by, a world that rustles, hums, and sings with the sounds of wild things.

    We all have one, but most of us will never see one. The heart surgeon now has that privilege but, for centuries, the heart was out of reach even for surgeons. So when a surgeon nowadays opens up a ribcage and mends a heart, it remains something of a miracle, even if, to some, it is merely plumbing. As with plumbers, the quality of surgeons’ work varies. As with plumbers, surgeons’ opinion of their own prowess and their own attitude to risk are not always reliable. Measurement is key. We’ve had a century of effective evidence-based medicine. We’ve had barely a decade of thorough monitoring of clinical outcomes. Thanks to the ground-breaking risk modelling of pioneering surgeons like Samer Nashef, we at last know how to judge whether an operation is in a patient’s best interest, which hospital and surgeon would be best for that operation, when it might best be performed and what the exact level of risk is. We have at last made what is important in surgery measurable. But how should surgeons, and their patients, use these newfound insights? Ever since his days as a medical student, Samer Nashef has challenged the medical profession to be more open and more accurate about the success of surgical procedures, for the sake of the patients. In The Naked Surgeon, he unclothes his own profession to demonstrate to his reader (and prospective patient) many revelations, such as the paradox at the heart of the cardiac surgeon’s craft: the more an operation is likely to kill you, the better it is for you. And he does so with absolute clarity, fluency and not a little wit.

    Focusing on four specific examples — corn, silkworms, domestic cats, and apples — she traces the histories of species that have been fundamentally altered over the centuries by the whims and needs of people.

    Maybe they’re even suspicious of it. John Coltrane’s saxophonic flights of fancy, Jimi Hendrix’s feedback drenched guitar solos, Ravi Shankar’s sitar extrapolations—all these sounds seem like so much noodling or jamming, indulgent self-expression. “Just” improvising, as is sometimes said. For these music fans, it seems natural that music is meant to be composed. In the first book of its kind, John Corbett’s A Listener’s Guide to Free Improvisation provides a how-to manual for the most extreme example of spontaneous improvising: music with no pre-planned material at all. Drawing on over three decades of writing about, presenting, playing, teaching, and studying freely improvised music, Corbett offers an enriching set of tools that show any curious listener how to really listen, and he encourages them to enjoy the human impulse— found all around the world— to make up music on the spot.           Corbett equips his reader for a journey into a difficult musical landscape, where there is no steady beat, no pre-ordained format, no overarching melodic or harmonic framework, and where tones can ring with the sharpest of burrs. In “Fundamentals,” he explores key areas of interest, such as how the musicians interact, the malleability of time, overcoming impatience, and watching out for changes and transitions; he grounds these observations in concrete listening exercises, a veritable training regime for musical attentiveness. Then he takes readers deeper in “Advanced Techniques,” plumbing the philosophical conundrums at the heart of free improvisation, including topics such as the influence of the audience and the counterintuitive challenge of listening while asleep. Scattered throughout are helpful and accessible lists of essential resources—recordings, books, videos— and a registry of major practicing free improvisors from Noël Akchoté to John Zorn, particularly essential because this music is best experienced live.           The result is a concise, humorous, and inspiring guide, a unique book that will help transform one of the world’s most notoriously unapproachable artforms into a rewarding and enjoyable experience.

    

    Around 95% of all living species died out--a global catastrophe far greater than the dinosaurs' demise 65 million years ago. How this happened remains a mystery. But there are many competing theories. Some blame huge volcanic eruptions that covered an area as large as the continental United States; others argue for sudden changes in ocean levels and chemistry, including burps of methane gas; and still others cite the impact of an extraterrestrial object, similar to what caused the dinosaurs' extinction. Extinction is a paleontological mystery story. Here, the world's foremost authority on the subject provides a fascinating overview of the evidence for and against a whole host of hypotheses concerning this cataclysmic event that unfolded at the end of the Permian.After setting the scene, Erwin introduces the suite of possible perpetrators and the types of evidence paleontologists seek. He then unveils the actual evidence--moving from China, where much of the best evidence is found; to a look at extinction in the oceans; to the extraordinary fossil animals of the Karoo Desert of South Africa. Erwin reviews the evidence for each of the hypotheses before presenting his own view of what happened.Although full recovery took tens of millions of years, this most massive of mass extinctions was a powerful creative force, setting the stage for the development of the world as we know it today.
