It was studied from antiquity to the Renaissance as a way of glimpsing the nature of reality. Geometry is number in space; music is number in time; and comology expresses number in space and time. Number, music, and geometry are metaphysical truths: life across the universe investigates them; they foreshadow the physical sciences.Quadrivium is the first volume to bring together these four subjects in many hundreds of years. Composed of six successful titles in the Wooden Books series-Sacred Geometry, Sacred Number, Harmonograph, The Elements of Music, Platonic & Archimedean Solids, and A Little Book of Coincidence-it makes ancient wisdom and its astonishing interconnectedness accessible to us today.Beautifully produced in six different colors of ink, Quadrivium will appeal to anyone interested in mathematics, music, astronomy, and how the universe works.

    In fact, as @WAR shows, U.S. hackers were crucial to our victory in Iraq. Shane Harris delves into the frontlines of America’s new cyber war. As recent revelations have shown, government agencies are joining with tech giants like Google and Facebook to collect vast amounts of information. The military has also formed a new alliance with tech and finance companies to patrol cyberspace, and Harris offers a deeper glimpse into this partnership than we have ever seen before. Finally, Harris explains what the new cybersecurity regime means for all of us, who spend our daily lives bound to the Internet — and are vulnerable to its dangers.

    The theme of Heisenberg's exposition is that words and concepts familiar in daily life can lose their meaning in the world of relativity and quantum physics. This in turn has profound philosophical implications for the nature of reality and for our total world view.

    Presenting an introduction to the philosophy, history and methodology of geography, the book maps the intellectual changes in the discipline over the years. To keep the students abreast with the recent trends in geography, and its methodological problems, the book has been updated and revised, making it a comprehensive textbook on geographical thought. The main objective of the sixth edition is to incorporate a number of relevant new topics and concepts to streamline the text which may go a long way in expanding the geographical base of the interested students about the philosophy and methodology of geography. This new edition is presented in a larger format with all improved maps and illustrations. A whole new chapter now introduces to the students a contemporary sub-discipline of Feminist Geography. A new comprehensive list of biographic notes on selected geographers is also included in this edition. It is hoped that the present edition will prove of immense help for the students and teachers of geography alike. It will also serve the need of the aspirants of various competitive examinations, especially the Indian Administrative Service, the NET and other state level civil services examinations.

    When weapons builders detonated the first hydrogen bomb in 1952, they tapped into the vastest source of energy in our solar system--the very same phenomenon that makes the sun shine. Nuclear fusion was a virtually unlimited source of power that became the center of a tragic and comic quest that has left scores of scientists battered and disgraced. For the past half-century, governments and research teams have tried to bottle the sun with lasers, magnets, sound waves, particle beams, and chunks of metal, have struggled to harness the power of fusion. (The latest venture, a giant, multi-billion-dollar, international fusion project called ITER, is just now getting underway.) Again and again, they have failed, disgracing generations of scientists. Throughout this fascinating journey Charles Seife introduces us to the daring geniuses, villains, and victims of fusion science: the brilliant and tortured Andrei Sakharov; the monomaniacal and Strangelovean Edward Teller; Ronald Richter, the secretive physicist whose lies embarrassed an entire country; and Stanley Pons and Martin Fleischmann, the two chemists behind the greatest scientific fiasco of the past hundred years. Sun in a Bottle is the first major book to trace the story of fusion from its beginnings into the 21st century, of how scientists have gotten burned by trying to harness the power of the sun.

    I thought I’d leave the red-headed stranger with dark green eyes behind and good freaking riddance. Except he’s not even close to being gone. Mason McConnell is everywhere, drawing me in, like an invisible thread. I just hope that string doesn't snap and break my heart. Mason: Two weeks was all I needed to go home, spread my cat’s ashes, and visit my brother. But one foolish decision at the airport managed to throw all my plans off track. Somehow, I had unknowingly cast the line, and Charlotte Kelley took the bait. The chatty, prying American somehow had a way of bringing me back to life. I didn’t want her under my skin, and I certainly wasn’t expecting her to make her way into my heart, yet once she did, I didn’t want her to leave. But with one secret wedged between us, I'm not sure I have the right to ask her to stay.

    We have a consumption crisis. And this book, which takes aim at cherished assumptions regarding energy, offers refreshingly straight talk about what’s wrong with the way we think and talk about the problem. Though we generally believe we can solve environmental problems with more energy—more solar cells, wind turbines, and biofuels—alternative technologies come with their own side effects and limitations. How, for instance, do solar cells cause harm? Why can’t engineers solve wind power’s biggest obstacle? Why won’t contraception solve the problem of overpopulation lying at the heart of our concerns about energy, and what will? This practical, environmentally informed, and lucid book persuasively argues for a change of perspective. If consumption is the problem, as Ozzie Zehner suggests, then we need to shift our focus from suspect alternative energies to improving social and political fundamentals: walkable communities, improved consumption, enlightened governance, and, most notably, women’s rights. The dozens of first steps he offers are surprisingly straightforward. For instance, he introduces a simple sticker that promises a greater impact than all of the nation’s solar cells. He uncovers why carbon taxes won’t solve our energy challenges (and presents two taxes that could). Finally, he explores how future environmentalists will focus on similarly fresh alternatives that are affordable, clean, and can actually improve our well-being. Watch a book trailer.

    As bewilderingly diverse then as the beetle is today, they survived in the arctic or the tropics, were spiky or smooth, were large as lobsters or small as fleas. And because they flourished for three hundred million years, they can be used to glimpse a less evolved world of ancient continents and vanished oceans. Erudite and entertaining, this book is a uniquely exuberant homage to a fabulously singular species.

    But almost everything about it, from the elements that forged stars, planets, and lifeforms, to the fundamental forces of physics, can be traced back to what happened in just the first three minutes of its life.In this book, Nobel Laureate Steven Weinberg describes in wonderful detail what happened in these first three minutes. It is an exhilarating journey that begins with the Planck Epoch - the earliest period of time in the history of the universe - and goes through Einstein's Theory of Relativity, the Hubble Red Shift, and the detection of the Cosmic Microwave Background. These incredible discoveries all form the foundation for what we now understand as the "standard model" of the origin of the universe. The First Three Minutes examines not only what this model looks like, but also tells the exciting story of the bold thinkers who put it together.Clearly and accessibly written, The First Three Minutes is a modern-day classic, an unsurpassed explanation of where it is we really come from.

    Russell's classic The Principles of Mathematics sets forth his landmark thesis that mathematics and logic are identical―that what is commonly called mathematics is simply later deductions from logical premises.His ideas have had a profound influence on twentieth-century work on logic and the foundations of mathematics.

    It provides short gaming exercises that illustrate the subtleties of systems thinking. The companion DVD shows the authors introducing and running each of the thirty games. The thirty games are classified by these areas of learning: Systems Thinking, Mental Models, Team Learning, Shared Vision, and Personal Mastery. Each description clearly explains when, how, and why the game is useful. There are explicit instructions for debriefing each exercise as well as a list of all required materials. A summary matrix has been added for a quick glance at all thirty games. When you are in a hurry to find just the right initiative for some part of your course, the matrix will help you find it. Linda Booth Sweeney and Dennis Meadows both have many years of experience in teaching complex concepts. This book reflects their insights. Every game works well and provokes a deep variety of new insights about paradigms, system boundaries, causal-loop diagrams, reference modes, and leverage points. Each of the thirty exercises here was tested and refined many times until it became a reliable source of learning. Some of the games are adapted from classics of the outdoor education field. Others are completely new. But all of them complement readings and lectures to help participants understand intuitively the principles of systems thinking. Biography Linda Booth Sweeney, Ed. D., is a researcher and writer dedicated to making the principles of systems thinking and sustainability accessible to children and others. She has worked with Outward Bound, Sloan School of M.I.T., and Schlumberger Excellence in Educational Development, or SEED. She is the author of The Systems Thinking Playbook; When a Butterfly Sneezes: A guide for helping children explore interconnections in our world through favorite stories; The SEED Water Book ; and numerous academic journals and newsletters.

    Yet there’s a black hole at the heart of biology. We do not know why complex life is the way it is, or, for that matter, how life first began. In The Vital Question, award-winning author and biochemist Nick Lane radically reframes evolutionary history, putting forward a solution to conundrums that have puzzled generations of scientists.For two and a half billion years, from the very origins of life, single-celled organisms such as bacteria evolved without changing their basic form. Then, on just one occasion in four billion years, they made the jump to complexity. All complex life, from mushrooms to man, shares puzzling features, such as sex, which are unknown in bacteria. How and why did this radical transformation happen?The answer, Lane argues, lies in energy: all life on Earth lives off a voltage with the strength of a lightning bolt. Building on the pillars of evolutionary theory, Lane’s hypothesis draws on cutting-edge research into the link between energy and cell biology, in order to deliver a compelling account of evolution from the very origins of life to the emergence of multicellular organisms, while offering deep insights into our own lives and deaths.Both rigorous and enchanting, The Vital Question provides a solution to life’s vital question: why are we as we are, and indeed, why are we here at all?
