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.

    The black mass crashed through the local school. 144 people were killed. 116 were schoolchildren. Gaynor Madgwick was there. She was eight and severely injured. In this book, Gaynor tells her own story and interviews people affected by the day's events. "Gaynor Madgwick was pulled injured from one of the classrooms where her friends died. She was left behind to live out her life. This is her story, sad, sweet, sentimental, and authentic. I commend it to you." - Vincent Kane, Broadcaster "Gaynor Madgwick's sense of injustice is palpable in her clear, riveting account of this scandal and its human cost. Despite everything, however, she is not bitter and retains the quiet dignity that is, perhaps, the true and lasting legacy of Aberfan." - Frank Olding, Planet Magazine "Madgwick does not dwell too much on the politics of Aberfan, and this is left largely to an incisive introduction by the veteran broadcaster, Vincent Kane, who leaves us in no doubt where the responsibility lay for the disaster. Thankfully Madgwick has now found happiness after a troubled life, having had to live with the guilt of the survivor for all her life. And writing so sensitively has helped her to come to terms with what happened in 1966. This is certainly not an easy book to read, but as noted by Lord Snowdon, it should and must be read by all of us in memory of those who died, whilst not forgetting those who also survived this tragic event." - Richard E. Huws, Gwales

    An entertaining, insightful history of the men who've held the office, from the division between Jefferson and Hamilton through Bill Clinton's campaign for national health care.

    The view 16-year-old Thomas Osborne first had of Muskoka was at night, trudging alone with his even younger brother along unmarked primitive roads to find their luckless father who, in 1875, had decided to make a new start for his beleaguered family on some "free land" in the bush east of the pioneer village of Huntsville, Ontario. The miracle is that Thomas lived to tell the tale.For the next five years Thomas endured starvation, falling through the ice and freezing, accidents with axes and boats, and narrow escapes from wolves and bears. Many years later, after returning to the United States, Osborne wrote down all his adventures in a graphic memoir that has become, in the words of author and journalist Roy MacGregor, "an undiscovered Canadian classic."Reluctant Pioneer provides a brooding sense of adventure and un- sentimental realism to deliver a powerful account of pioneer life where tragedies arrive as naturally as rain and where humour resides in irony.

    Each story is accompanied by scripture, prayer, and discussion exercises designed to remind readers of Mary of Medjugorje's intercession on their behalf and God's personal love for them. Watkins gives nationwide talks and workshops and works as a spiritual director in the Bay Area, in addition to maintaining an active website and e-mail newsletter.

    It turns out that the Neanderthals’ behavior was surprisingly modern: they buried the dead, cared for the sick, hunted large animals in their prime, harvested seafood, and communicated with spoken language. Meanwhile, advances in DNA technologies are compelling us to reassess the Neanderthals’ place in our own past.For hundreds of thousands of years, Neanderthals evolved in Europe parallel to Homo sapiens evolving in Africa, and, when both species made their first forays into Asia, the Neanderthals may even have had the upper hand. In this important volume, Dimitra Papagianni and Michael A. Morse compile the first full chronological narrative of the Neanderthals’ dramatic existence—from their evolution in Europe to their expansion to Siberia, their subsequent extinction, and ultimately their revival in popular novels, cartoons, cult movies, and television commercials.

    The search for little Pearl consumed the next several weeks, and the story became front page news all over the United States. Hundreds of residents from the nearby towns of Waldron and Booneville Arkansas helped in the search, and a mysterious mountain hermit seemed to hold the secret to Pearl's disappearance. The incredible events that followed contributed to a mountain legend that still exists today.

    Photographer Glen Denny was a key figure in this golden age of climbing, capturing pioneering feats on camera while tackling challenging ascents himself.In entertaining short pieces enlivened by his iconic black-and-white images of Yosemite's big wall legends, Denny reveals a young man's coming of age and provides a vivid look at Yosemite’s early climbing culture. He relates such precarious achievements as hauling water in glass gallon jugs up the east face of Washington Column, nailing the 750-foot Rostrum in a punishing heat wave, and dangling overnight on El Capitan’s Dihedral Wall in a lightning storm. Each true tale captures the spirit of historic Camp 4, where Denny and others plan the next big climb while living on the cheap and dodging park rangers.

    Our sense of its age was vague and vastly off the mark, and much of the knowledge of our own species’ history was a set of fantastic myths and fairy tales. In the tradition of The Microbe Hunters and Gods, Graves, and Scholars, Sean Carroll leads a rousing voyage that recounts the most important discoveries in two centuries of natural history: from Darwin’s trip around the world to Charles Walcott’s discovery of pre-Cambrian life in the Grand Canyon; from Louis and Mary Leakey’s investigation of our deepest past in East Africa to the trailblazers in modern laboratories who have located a time clock in our DNA.

    The news is full of archaeology: treasures found (British king under parking lot) and treasures lost (looters, bulldozers, natural disaster, and war). Archaeological research tantalizes us with possibilities (are modern humans really part Neandertal?). Where are the archaeologists behind these stories? What kind of work do they actually do, and why does it matter?Marilyn Johnson’s Lives in Ruins is an absorbing and entertaining look at the lives of contemporary archaeologists as they sweat under the sun for clues to the puzzle of our past. Johnson digs and drinks alongside archaeologists, chases them through the Mediterranean, the Caribbean, and even Machu Picchu, and excavates their lives. Her subjects share stories we rarely read in history books, about slaves and Ice Age hunters, ordinary soldiers of the American Revolution, children of the first century, Chinese woman warriors, sunken fleets, mummies.What drives these archaeologists is not the money (meager) or the jobs (scarce) or the working conditions (dangerous), but their passion for the stories that would otherwise be buried and lost.

    Cheeky, funny and never fawning, Heat was a new source of celeb info when it started in 2000.

    Darwin wondered why these birds were confined to remote islands at the tip of South America, sensing a larger story, but he set this mystery aside and never returned to it. Almost two hundred years later, Jonathan Meiburg takes up this chase. He takes us through South America, from the fog-bound coasts of Tierra del Fuego to the tropical forests of Guyana, in search of these birds: striated caracaras, which still exist, though they're very rare. He reveals the wild, fascinating story of their history, origins, and possible futures. And along the way, he draws us into the life and work of William Henry Hudson, the Victorian writer and naturalist who championed caracaras as an unsung wonder of the natural world, and to falconry parks in the English countryside, where captive caracaras perform incredible feats of memory and problem-solving. A Most Remarkable Creature is a hybrid of science writing, travelogue, and biography, as generous and accessible as it is sophisticated, and absolutely riveting.

    But ask a physicist and there’s no doubt that James Clerk Maxwell will be near the top of the list.  Maxwell, an unassuming Victorian Scotsman, explained how we perceive colour. He uncovered the way gases behave. And, most significantly, he transformed the way physics was undertaken in his explanation of the interaction of electricity and magnetism, revealing the nature of light and laying the groundwork for everything from Einstein’s special relativity to modern electronics.   Along the way, he set up one of the most enduring challenges in physics, one that has taxed the best minds ever since. ‘Maxwell’s demon’ is a tiny but thoroughly disruptive thought experiment that suggests the second law of thermodynamics, the law that governs the flow of time itself, can be broken. This is the story of a groundbreaking scientist, a great contributor to our understanding of the way the world works, and his duplicitous demon.
