In Galaxies, Or Graur offers a brief and fascinating overview of the history, physics, and astrophysical uses of galaxies. Starting with the history of the last two thousand years of galaxy studies, Graur discusses the types of galaxies we observe and the physics that drive them; the myths and physical structure of the Milky Way; how galaxies were used to discover and study the mysterious phenomena of dark matter and dark energy; and how scientists think galaxies formed shortly after the Big Bang and evolved to their present forms.Tracing galaxy studies back thousands of years ago to their beginnings, Graur describes their origin in Ptolemy's book Almagest, which was written in the first century CE. Almagest catalogued hundreds of stars and a few hazy cloud-like objects, one of which was the Andromeda galaxy. The listener will also encounter in this book well-known figures such as William Herschel, who, along with his sister Caroline, discovered hundreds of galaxies and lay the foundations for modern galaxy studies, as well as lesser-known astronomers, including tenth-century Persian astronomer Abd al-Rahman al-Sufi. Galaxies concludes by showing listeners how they can get involved in galaxy studies themselves and do their part to fight the light pollution that today obscures the Milky Way and all but the brightest of stars.Ver livro

Keep Sharp is Dr. Sanjay Gupta’s comprehensive guide to cognitive dysfunction disease in its various forms, including dementia, and the prevention, treatment, and strategies to cope. Gupta bravely initiated a noble and global quest to gather up and analyze how doctors tackle brain function problems and cognitive challenges. He holds an impressive list of characters and anecdotes from his efforts.. Keep Sharp appeals to a diversified bevy of readers as a double gem for popular science and medical advice. Although avoiding medical jargon is impossible for cognitive dysfunction, Gupta shows us a simplified, engaging, and compelling story built around one of the most complex objects we know of—the human brain. Defining his terms right out of the gate gives the reader what they need to understand and act upon. The reader begins to learn how our physical and mental activities effect our brains. Boosting one’s brain prowess with medically established methods to help prevent Alzheimer's’ arises as a dominant theme. Dr. Gupta sculpted his narrative's contents with plenty of advice for those who show symptoms of the first stages of dementia. He puts his arm around the reader, tells him or her how to get the help they need, secure a proper diagnosis, and how to come to grips with the most adverse effects. Gupta pieces together valuable resources in the final chapter to guide those who carry a diagnosis of dementia. Though his approach is predictably straightforward and practical, he infuses it with the empathy and understanding of a good doctor. His goal: bring the issue of Alzheimer’s, its significance, its challenges, and possible solutions to a broader audience. This book is not intended as medical advice. If you have health problems, consult with your physician. Rather than replace Dr. Gupta's book, it serves to complement.it.Ver livro
In Storms of My Grandchildren, James Hansen-the nation's leading scientist on climate issues-speaks out for the first time with the full truth about global warming: the planet is hurtling even more rapidly than previously acknowledged to a climatic point of no return. Although Hansen was Al Gore's science adviser for the 2006 documentary An Inconvenient Truth, his recent data shows that our situation is even more dire today. But politicians haven't made the connection between the policy and the science. Hansen shows why Gore's solution-cap and trade-won't work, why we must phase out all coal, and why 350 ppm of carbon is a goal we must achieve in the next two decades if our children and grandchildren are to avoid global meltdown and the storms of the book's title. This urgent manifesto bucks conventional wisdom (including the Kyoto Protocol) and is sure to stir controversy, but Hansen-whose climate predictions have come to pass again and again, beginning in the 1980s when he first warned Congress about global warming-is the single most credible voice on the subject worldwide.Hansen paints a devastating but all-too-realistic picture of what will happen in the near future, mere years and decades from now, if we follow the course we're on. But he is also an optimist, showing that there is still time to do what we need to save the planet. Urgent, strong action is needed, and this book, released just before the Copenhagen Conference in December 2009, will be key in setting the agenda going forward to create a groundswell, a tipping point, to save humanity from a dire fate more imminent than we had supposed.Ver livro
Did you know we have 100,000 heartbeats a day? That's a lot of wear and tear over the years as we age. Natural aging leads to artery plaque, high blood pressure, and slower and irregular heartbeats. You can do everything right, and time will still pass. You will still age. While you can influence some aspects of aging on your own, some you cannot - at least not without your doctor's help. Fortunately, the biology of aging is no longer mysterious. Heart and blood vessel health is knowable, measurable, and manageable. In You Can Prevent a Stroke, Dr. Joshua Yamamoto and Dr. Kristin Thomas help us understand what we can do, and what we can ask of our doctors, to manage the effects of aging on our circulation so that we do not have a stroke. For years, they have approached patients with the fundamentals learned at The Johns Hopkins Hospital: "Take responsibility for your patient's health, go in-depth, have an unswerving commitment to solving problems, be thorough, thoughtful, and have attention to detail." Strokes are usually said to be tragic and random. They are certainly tragic, but they are not random. Strokes can be avoided, and You Can Prevent a Stroke explains how.Ver livro
How well do we really know dogs? People may enjoy thinking about them as "man's best friend," but what actually drives the things they do? What is going on in their fur-covered heads as they look at us with their big, expressive eyes? Raymond Coppinger and Mark Feinstein know something about these questions, and with How Dogs Work, they're ready to share; this is their guide to understanding your dog and its behavior.Approaching dogs as a biological species rather than just as pets, Coppinger and Feinstein accessibly synthesize decades of research and field experiments to explain the evolutionary foundations underlying dog behaviors. They examine the central importance of the shape of dogs: how their physical body affects behavior, how shape interacts with the environment as animals grow, and how all of this has developed over time. Shape, they tell us, is what makes a champion sled dog or a Border collie that can successfully herd sheep. Other chapters in How Dogs Work explore such mysteries as why dogs play; whether dogs have minds, and if so, what kinds of things they might know; why dogs bark; how dogs feed and forage; and the influence of the early relationship between mother and pup.Ver livro
