    Well, I was diagnosed 24 years ago, and I still learned something new on every page.”—Michael Kinsley, Vanity Fair columnist and author of Old Age: A Beginner’s Guide Here is the book that John Vine and his wife, Joanne, wish they could have consulted when John was first diagnosed with Parkinson’s disease—a nontechnical, personal guide written from the patient’s perspective. Relying on his experiences over the past 12 years, John writes knowledgeably about all aspects of the disease. John also interviewed other Parkinson’s patients and their partners, whose stories and advice he includes throughout the book. “I wish we’d had John Vine’s book when my brother-in-law was diagnosed. The book is highly informative, unflinchingly honest, and reassuringly optimistic. It’s just what the doctor should have ordered.”—Cokie Roberts, best-selling author and political commentator on ABC News and NPR “John Vine details, in a compelling and accessible way, his experience with Parkinson’s disease. His book is an extraordinary guide to living successfully with Parkinson’s, and a must read for all who want to better understand the condition. Although diagnosed with Parkinson’s, my father lived an active and productive life until his death at age 94. As the book makes clear, while each patient’s journey is unique, common approaches are indispensable in treating the symptoms of the disease.”—Eric H. Holder, Jr. served as the 82nd Attorney General of the United States from 2009 to 2015 “John Vine has written the best primer I’ve ever read for newly diagnosed Parkinson’s patients and their families. It helps them cope with the shock of diagnosis, gives them (jargon-free) the scientific basics they need to know, describes the symptoms they may experience (making clear that every case is different) and catalogs the resources available to navigate living with Parkinson’s. John humanizes the book by describing his own experience and that of 22 other patients and their partners. I’d urge every neurologist to have copies of Vine’s primer on hand to help new PD on their journey forward.”—Morton Kondracke, author of Saving Milly: Love, Politics and Parkinson’s Disease and a member of the Founders' Council of the Michael J. Fox Foundation “My husband has PD, and I devoured this book. It’s wise, wonderfully readable, and, above all, helpful. Since John Vine has PD, he speaks with great authority about the challenges, both physical and psychological. If you have Parkinson’s, live with someone who has it, or just know someone battling the disease, A Parkinson’s Primer is for you.”—Lesley Stahl, award-winning television journalist on the CBS News program 60 Minutes “This is a remarkable book describing the personal experiences of many individuals, including the author, living with Parkinson’s disease. It captures the fact that although there are many possible symptoms in this disease, each person experiences different symptoms and copes with them in various ways. The thoughtful and insightful comments and coping strategies should be helpful for persons with PD, and their partners, regardless of the stage of the disease.”—Stephen Grill, MD, PhD, Director of the Parkinson’s & Movement Disorders Center of Maryland John M. Vine is a lawyer at Covington & Burling LLP in Washington, DC, where he is the senior member and former head of the firm’s employee benefits group. He was diagnosed with Parkinson’s in 2004.

    

    

    In building his case, Gould shows why the common assumption of an inescapable conflict between science and the humanities is false, mounts a spirited rebuttal to the ideas that his intellectual rival E. O. Wilson set forth in his book Consilience, and explains why the pursuit of knowledge must always operate upon the bedrock of nature' s randomness. The Hedgehog, the Fox, and the Magister’s Pox is a controversial discourse, rich with facts and observations gathered by one of the most erudite minds of our time.

    It defines our experience of the world; it echoes through our every waking hour. Time is the very foundation of conscious experience. Yet as familiar as it is, time is also deeply mysterious. We cannot see, hear, smell, taste, or touch it. Yet we do "feel" it--or at least we "think" we feel it. No wonder poets, writers, philosophers, and scientists have grappled with time for centuries.In his latest book, award-winning science writer Dan Falk chronicles the story of how humans have come to understand time over the millennia, and by drawing from the latest research in physics, psychology, and other fields, Falk shows how that understanding continues to evolve. "In Search of Time" begins with our earliest ancestors' perception of time and the discoveries that led--with much effort--to the Gregorian calendar, atomic clocks, and "leap seconds." Falk examines the workings of memory, the brain's remarkable "bridge across time," and asks whether humans are unique in their ability to recall the past and imagine the future. He explores the possibility of time travel, and the paradoxes it seems to entail. Falk looks at the quest to comprehend the beginning of time and how time--and the universe--may end. Finally, he examines the puzzle of time's "flow," and the remarkable possibility that the passage of time may be an illusion.Entertaining, illuminating, and ultimately thought provoking, "In Search of Time "reveals what some of our most insightful thinkers have had to say about time, from Aristotle to Kant, from Newton to Einstein, and continuing with the brightest minds of today.

    The most trusted sources in the auto industry have called its Model S the most advanced, safest and best-performing car ever built - and it doesn’t use a drop of gasoline. Tesla has changed the way the public perceives electric vehicles, and inspired the major automakers to revive their own dormant efforts to sell EVs. However, even amidst the avalanche of media coverage that followed the triumph of the Model S, few have grasped the true significance of what is happening. Tesla has redefined the automobile, sparked a new wave of innovation comparable to the internet and mobile computing revolutions, and unleashed forces that will transform not just the auto industry, but every aspect of society. The Tesla story is one part of an ongoing tide of change driven by the use of information technology to eliminate “friction” such as geographic distance, middlemen and outdated regulations. Tesla is simply applying the new order to the auto industry, but the automobile is such a pervasive influence in our lives that redefining how it is designed, built, driven and sold will have sweeping effects in unexpected areas. Just as Tesla built the Model S as an electric vehicle “from the ground up,” it has taken an outsider’s approach to the way it markets its cars. Its direct sales model has drawn legal challenges from entrenched auto dealers, who fear that their outdated business model will be destroyed. Its systems approach to the software and electronics in its cars has highlighted how far behind the technological times the major automakers are. It’s easy to see why readers find Tesla irresistible. CEO Elon Musk is a superstar entrepreneur, a “nauseatingly pro-US” immigrant and the leader of two other cutting-edge companies. Tesla dares to challenge the establishment behemoths and, so far at least, has handily beaten them at their own game. In this history of the 21st century’s most exciting startup, Charles Morris begins with a brief history of EVs and a biography of Tesla’s driving force, Elon Musk. He then details the history of the company, told in the words of the Silicon Valley entrepreneurs who made it happen. There are many fascinating stories here: Martin Eberhard’s realization that there were many like himself, who loved fast cars but wanted to help the environment and bring about the post-oil age; the freewheeling first days, reminiscent of the early internet era; the incredible ingenuity of the team who built the Roadster; Tesla’s near-death experience and miraculous resurrection; the spiteful split between the company’s larger-than-life leaders; the gloves-off battles with hostile media such as Top Gear and the New York Times; and the media’s ironic about-face when the magnificent Model S won the industry’s highest honors, and naysayers became cheerleaders overnight. And the story is just beginning: Tesla has breathtakingly ambitious plans for the future.This book was updated May 1, 2015 to include the latest on the Gigafactory and the D package.

    'A focused snapshot of a brave new world.' - Nature In 2018 the world woke up to gene editing with a storm of controversy over twin girls born in China with genetic changes deliberately introduced by scientists – changes they will pass on to their own offspring. Genetic modification (GM) has been with us for 45 years now, but the new system known as CRISPR or gene editing can manipulate the genes of almost any organism with a degree of precision, ease and speed that we could only dream of ten years ago. But is it ethical to change the genetic material of organisms in a way that might be passed on to future generations? If a person is suffering from a lethal genetic disease, is it unethical to deny them this option? Who controls the application of this technology, when it makes ‘biohacking’ – perhaps of one’s own genome – a real possibility?Nessa Carey’s book is a thrilling and timely snapshot of a cutting-edge technology that will radically alter our futures and the way we prevent disease.

    David Christian, professor of history at San Diego State University, surveys the past at all possible scales, from conventional history, to the much larger scales of biology and geology, to the universal scales of cosmology.
