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.

         Ronan O'Gara has been at the heart of Munster and Irish rugby for the past fifteen years. Now, as he comes to the end of a glittering playing career, it is time for him to reflect on those many successes and occasional failures with the straight-talking attitude that has become his trademark. Never one to shy away from the truth, the result is Ronan O'Gara: Unguarded.     Packed full of anecdotes and analysis of the teammates O'Gara has been proud to share the shirt with, and of the coaches he has played under -- often in controversial circumstances -- this is the definitive record of an era when Munster rose to triumph in Europe, and Ireland to win the Grand Slam, before crashing down to earth again. It is simply the must-have rugby book of the year.

     Photographic Histograms are unique to Digital Photography. Most books on the subject of Photographic Histograms only discuss the Luminosity Histogram that is projected on the LCD screens of Digital cameras. There are three other types of Histograms that you should know about -- RGB, Colors, and Color Channel.Most books also only describe the basics of how to use the Luminosity Histogram to set exposure. In this relatively short but fact filled book you will learn how histograms are created and their significance to photography.Though they did not exist in the days of film photography, they are closely related to the Exposure Zones System created by Ansel Adams and Fred Archer around 1939. Can you identify with any of these experiences? Do your eyes glaze over when people talk about histograms? Do you feel that histograms are too technical for you? Are you enthused about photography but confused by all the technical jargon? Do you wonder how professional photographers get such great images? Are you tired of well-intentioned friends giving you bad advice about photography? If you answered yes to any of these questions, end the frustration. Just scroll up and grab a copy today.

    As Johnny Knoxville so succinctly put it, Nieratko is an asshole, but whether Chris is rescuing a stalker from choking on her own vomit, getting his nose broken for having AIDS (he doesn't) or marrying the one woman that could put up with his insanity, his life sounds so much like a collection of hilarious bar stories it's impossible not to grab a beer and listen to the whole thing.

    This behavior is very much different from what we humans are used to dealing with in our everyday lives, so naturally this subject is quite hard to comprehend for many. We believed that the best way to introduce the subject reliably is to start at the beginning, presenting the observations, thoughts and conclusions of each of the world’s greatest physicists through their eyes, one at a time. In this way we hope that the reader may take an enjoyable journey through the strange truths of quantum theory and understand why the conclusions of these great minds are what they are. This book starts with the most general view of the world and gradually leads readers to those new, unbelievable but real facts about the very nature of our universe.

    Fuzzy brown molds mischievously turn forgotten peaches to slime in the kitchen fruit bowl. And in thousands of other ways, members of the kingdom Fungi do their part to make life on Earth the miracle that it is. In this lively book, George Hudler leads us on a tour of an often-overlooked group of organisms, which differ radically from both animals and plants. Along the way the author stops to ponder the marvels of nature and the impact of mere microbes on the evolution of civilization. Nature's ultimate recyclers not only save us from drowning in a sea of organic waste, but also provide us with food, drink, and a wide array of valuable medicines and industrial chemicals.Some fungi make deadly poisons and psychedelic drugs that have interesting histories in and of themselves, and Hudler weaves tales of those into his scientific account of the nature of the fungi. The role of fungi in the Irish potato famine, in the Salem Witch Trials, in the philosophical writings of Greek scholars, and in the creation of ginger snaps are just a few of the many great moments in history to grace these pages.Hudler moves so easily from discussing human history to exploring scientific knowledge, all with a sense of humor and enthusiasm, that one can well understand why he is an award-winning teacher both at Cornell University as well as nationally. Few, for instance, who read his invitation to get out of your chair and take a short walk will ever again look without curiosity and admiration at the rotten part of the world around them. Magical Mushrooms, Mischievous Molds is full of information that will satisfy history buffs, science enthusiasts, and anyone interested in nature's miracles. Everyone in Hudler's audience will develop a new appreciation of the debt they owe to the molds for such common products as penicillin, wine, and bread.

    Tesla's rare article, 'The Problem of Increasing Human Energy with Special Reference to the Harnessing of the Sun's Energy' is included. This lengthy article was originally publishing in the June 1900 issue of The Century Illustrated Monthly Magazine and it was the outline for Tesla's master blueprint for the world. Tesla's fantastic vision of the future, including wireless power, anti-gravity, free energy and highly advanced solar power. Also included are some of the papers, patents and material collected on Tesla at the Colorado Spring Tesla Symposiums. Tesla was the inventor of the radio before Marconi, and when he demonstrated wireless remote control to the US Navy in the late 1890s, they replied that it was too advanced! Tesla was an eccentric visionary and probably the greatest inventor who ever lived. His basic inventions power the world of today. What was his vision of tomorrow? Find out in The Tesla Papers.

    Above all, perhaps, Rutherford and the young men working under him were the first to split the atom, unlocking tremendous forces—forces, as Rutherford himself predicted, that would bring us the atomic bomb.Rutherford, awarded a Nobel Prize and made Baron Rutherford by the queen of England, was also a great ambassador of science, coming to the aid of colleagues caught in the Nazi and Soviet regimes. Under Rutherford’s rigorous and boisterous direction, a whole new generation of remarkable physicists emerged. In Richard Re’s hands, Rutherford leaps off the page, a ruddy, genial man and a towering figure in scientific history.

    These areas of knowledge have converged into a modern theory of epidemiology that has been slow to penetrate into textbooks, particularly at the introductory level. Epidemiology: An Introduction closes the gap. It begins with a brief, lucid discussion of causal thinking and causal inference and then takes the reader through the elements of epidemiology, focusing on the measures of disease occurrence and causal effects. With these building blocks in place, the reader learns how to design, analyze and interpret problems that epidemiologists face, including confounding, the role of chance, and the exploration of interactions. All these topics are layered on the foundation of basic principles presented in simple language, with numerous examples and questions for further thought.
