    How to Speak Science acquaints us not only with what scientists know, but how they think--so that each of us can reason like a physicist and appreciate the world in all its beautiful chaos."The perfect example of a geeky text that is neither condescending nor highfalutin. It has sufficient genuine scientific content to keep the techies interested, while being fast-paced enough (and at times genuinely funny) to keep the neophyte on board." --E&T Magazine

    If these galaxies had always been travelling, he reasoned, then they must, at some point, have been on top of one another. This discovery transformed the debate about one of the most fundamental questions of human existence - how did the universe begin?Every society has stories about the origin of the cosmos and its inhabitants, but now, with the power to peer into the early universe and deploy the knowledge gleaned from archaeology, geology, evolutionary biology and cosmology, we are closer than ever to understanding where it all came from.

    . . A riveting and anxiety-inducing read. Mike Pond tells his story of recovery from alcoholism with a brutally honest, warts-and-all approach that makes you want cheer for him and simultaneously slap him upside the head.” – Vancouver SunPsychotherapist Michael Pond is no stranger to the devastating consequences of alcoholism. He has helped hundreds of people conquer their addictions, but this knowledge did not prevent his own near-demise. In this riveting memoir, he recounts how he lost his Penticton-based practice, his home, and his family—all because of his drinking. After scores of visits to the ER, a tour of hellish recovery homes, a stint in intensive care for end-stage alcoholism, and jail, Pond devised his own personal plan for recovery. He met Maureen Palmer and together they investigated scientific alternatives to the rigid abstinence doctrine pushed by Alcoholics Anonymous.

    One island, two unique societies (Norse and Inuit). Only one of these societies would succeed--the other would fail. But how? With his trademark accessibility and comprehensiveness, Diamond documents how environmental damage, climate change, loss of friendly contacts and the rise of hostile ones, and the unique political, economic, and social settings of prehistoric Greenland combine to demonstrate exactly why and how societies choose to fail or succeed. Jared Diamond's latest book, "The World Until Yesterday: What Can We Learn from Traditional Societies?," is available from Viking.

    As recently as 1918, a pandemic of influenza claimed over 50 million lives worldwide. The advent of drugs and vaccines led to an era of hope when we thought our battles with infectious disease were won, but our optimism has been eroded by the recognition that many pathogens have the capacity to transform themselves and escape our efforts to eradicate them. Are we now facing an inevitable repeat of a calamity such as the 1918 influenza pandemic or the Black Death? Can we anticipate and thwart such an event, or are we wilfully creating the conditions that would promote the emergence of new and highly virulent human infectious disease?Sunetra Gupta is Professor of Theoretical Epidemiology at the University of Oxford specialising in infectious diseases. She holds a bachelor's degree from Princeton University and a Ph.D. from the University of London. She has been awarded the Scientific Medal by the Zoological Society of London and the Royal Society Rosalind Franklin Award for her scientific research.

    As was the case with Gore's first movie (An Inconvenient Truth), the movie is bursting with bad science, bad policy and some outright falsehoods. The storm events Gore addresses occur naturally, and there is little or no evidence they are being made worse from human activities: sea level is rising at the same rate it was before humans started burning fossil fuels; in Miami Beach the natural rise is magnified because buildings and streets were constructed on reclaimed swampland that has been sinking; the 9/11 memorial was not flooded by sea level rise from melting ice sheets, but a storm surge at high tide, which would have happened anyway and was not predicted by Gore in his first movie, as he claims; the Greenland ice sheet undergoes melt every summer, which was large in 2012 but then unusually weak in 2017; glaciers advance and retreat naturally, as evidenced by 1,000 to 2,000 year old tree stumps being uncovered in Alaska; rain gauge measurements reveal the conflict in Syria was not caused by reduced rainfall hurting farming there, and in fact the Middle East is greening from increasing CO2 in the atmosphere; agricultural yields in China have been rising, not falling as claimed by Gore. The renewable energy sources touted by Gore (wind and solar), while a laudable goal for our future, are currently very expensive: their federal subsidies per kilowatt-hour of energy produced are huge compared to coal, natural gas, and nuclear power. These costs are hidden from the public in increased federal and state tax rates. Gore is correct that "it is right to save humanity", but what we might need saving from the most are bad decisions that reduce prosperity and hurt the poor.

    Although necessary health care should be available to all who need it, he says, the current health-care debate assumes that everyone requires massive amounts of expensive care to stay healthy. Hadler urges that before we commit to paying for whatever pharmaceutical companies and the medical establishment tell us we need, American consumers need to adopt an attitude of skepticism and arm themselves with enough information to make some of their own decisions about what care is truly necessary. Each chapter of Worried Sick is an object lesson regarding the uses and abuses of a particular type of treatment, such as mammography, colorectal screening, statin drugs, or coronary stents. For consumers and medical professionals interested in understanding the scientific basis for Hadler's arguments, each topical chapter has an accompanying source chapter in which Hadler discusses the medical literature and studies that inform his critique. According to Hadler, a major stumbling block to rational health-care policy in the United States is contention over the very concept of what constitutes good health. By learning to distinguish good medical advice from persuasive medical marketing, consumers can make better decisions about their personal health and use that wisdom to inform their perspectives on health-policy issues.

    Michael Savage explains the origins of viruses and their impact on the U.S. With new and resurgent diseases resulting from unregulated immigration and a politicized public health system, Michael Savage sees the need for some changes - starting with the President and the Center for Disease Control telling us the truth. Savage makes his case for the government to enforce travel bans, the use of quarantines and the importance of proper border screenings. However, this is not a cure or treatment for any of these diseases. With Zika virus, tuberculosis, hepatitis, Enterovirus 68 and other new disease threats emerging across the U.S., Savage will explain ways to fortify your immune system and defend against these and other diseases. Drawing from his extensive training, Dr. Savage examines the benefits of using specific nutrients to boost the human immune system which, in turn, increases the odds of surviving a viral infection as well as preventing other diseases. Based on his knowledge of the politics of medicine being played by the Obama mandarins and his Ph.D. in Epidemiology and Nutrition from the University of California, Berkley, Dr. Savage presents solid information to protect your health. Whether you want to defend your body against deadly diseases, boost your immunity, or learn more about the government's impact on reemerging and imported diseases, DISEASES WITHOUT BORDERS is your source for informative, helpful, and potentially life-saving advice.

    This book brings together some of his nastiest and most irreverent pieces. Witty, sharp and brutally honest, this collection is certain to delight and provoke readers of all ages.

    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.

    Everything else can be made, bought or created. Our life is made up of around 600,000 hours and every second is of infinite value. We live in an attention economy where corporations are fighting for our time with the goal of monetizing our every second. The money we use loses value and devalues our time through inflation. When we work, we are exchanging our limited time for money whose quantity increases every year. It hasn’t always been this way. People used gold as money for a reason; it was also a limited resource. Now, what does the future hold?Valuing your time is the first step to improving your life. Knowing that your time is the only limited resource makes you more selective about the things you do, the people you spend your time with and the assets you choose to store your wealth in. Once you learn to appreciate your time, you will get busy doing the things you love and start making better financial choices.
