But for a series of choices, accidents and coincidences - any of which could have gone otherwise - your life would have been very different. The same goes for reality. We live in just one of many possible worlds - but we can imagine parallel universes in which dinosaurs still rule the Earth, the Russians got to the moon first, everyone's a vegetarian or time itself flows backwards. And that's just for starters. What if the laws of physics were different? What if robots become smarter than us? Or, if every human on the planet simply vanished tomorrow? The answers to these questions aren't just fun to consider, but reveal deep truths about our own universe.Join New Scientist on a thrilling journey through dozens of incredible but perfectly possible alternative realities, thought experiments and counterfactual histories - each shining a surprising and unexpected spotlight on life as we know it.

    No one could. Until now.Entanglement tells the astounding story of the scientists who set out to complete Einstein's work. With accesible language and a highly entertaining tone, Amir Aczel shows us a world where the improbable--from unbreakable codes to teleportation--becomes possible.

    This ideology, Professor Lipset observes, defines the limits of political debate in the United States and shapes our society.American Exceptionalism explains why socialism has never taken hold in the United States, why Americans are resistant to absolute quotas as a way to integrate blacks and other minorities, and why American religion and foreign policy have a moralistic, crusading streak.

    Together, they explain virtually everything about the world we live in. But, almost a century after their advent, most people haven't the slightest clue what either is about. Did you know that there's so much empty space inside matter that the entire human race could be squeezed into the volume of a sugar cube? Or that you grow old more quickly on the top floor of a building than on the ground floor? And did you realise that 1 percent of the static on a TV tuned between stations is a relic of the Big Bang?

    Chances are you've got some lithium on your person right now. But aside from powering a mobile twenty first-century lifestyle, the third element on the periodic table may also hold the key to an environmentally sustainable, oil-independent future. From electric cars to a "smart" power grid that can actually store electricity, letting us harness the powers of the sun and the wind and use them when we need them, lithium—a metal half as dense as water, created in the first minutes after the Big Bang and found primarily in some of the most uninhabitable places on earth—is the key to setting us on a path toward a low-carbon energy future. It's also shifting the geopolitical chessboard in profound ways.In Bottled Lightning, the science reporter Seth Fletcher takes us on a fascinating journey, from the salt flats of Bolivia to the labs of MIT and Stanford, from the turmoil at GM to cutting-edge lithium-ion battery start-ups, introducing us to the key players and ideas in an industry with the power to reshape the world. Lithium is the thread that ties together many key stories of our time: the environmental movement; the American auto industry, staking its revival on the electrification of cars and trucks; the struggle between first-world countries in need of natural resources and the impoverished countries where those resources are found; and the overwhelming popularity of the portable, Internet-connected gadgets that are changing the way we communicate. With nearly limitless possibilities, the promise of lithium offers new hope to a foundering American economy desperately searching for a green-tech boom to revive it.

    Language is informal, examples are vivid and lively, and the perspectivie is fresh. Based on lectures delivered to engineering students, this work will also be valued by scientists, engineers, technicians, businessmen, anyone facing energy challenges of the future.

    The author has simplified the subject to serve the needs of the non-specialists. This work will be a significant addition to the text books available on Islamic jurisprudence in English.

    New material in the third edition includes: - A new chapter--complete with colorful examples from Lloyds of London and Sumitomo Metals--on how risky behavior can lead to disaster in private markets.- An evaluation of the Federal Reserves role in reining in economic growth to prevent inflation, and the debate over whether its growth targets are too low.- A look at the collapse of the Mexican peso and the burst of Japans bubble economy.- A revised discussion of the federal budget deficit, including the growing concern that Social Security and Medicare payments to retiring baby boomers will threaten the solvency of the government. Finally, in the updated concluding section, the author provides three possible scenarios for the American economy over the next decade. He warns that we live in an age of diminished expectations, in which the voting public is willing to settle for policy drift--but with the first of the baby boomers turning 65 in 2011, the U.S. economy will not be able to drift indefinitely.

    

    

    Thomas Young devised it in the early 1800s to show that light behaves like a wave, and in doing so opposed Isaac Newton. Nearly a century later, Albert Einstein showed that light comes in quanta, or particles, and the experiment became key to a fierce debate between Einstein and Niels Bohr over the nature of reality. Richard Feynman held that the double slit embodies the central mystery of the quantum world. Decade after decade, hypothesis after hypothesis, scientists have returned to this ingenious experiment to help them answer deeper and deeper questions about the fabric of the universe.How can a single particle behave both like a particle and a wave? Does a particle exist before we look at it, or does the very act of looking create reality? Are there hidden aspects to reality missing from the orthodox view of quantum physics? Is there a place where the quantum world ends and the familiar classical world of our daily lives begins, and if so, can we find it? And if there's no such place, then does the universe split into two each time a particle goes through the double slit?With his extraordinarily gifted eloquence, Anil Ananthaswamy travels around the world and through history, down to the smallest scales of physical reality we have yet fathomed. Through Two Doors at Once is the most fantastic voyage you can take.
