The Weather Channel, now America's most watched programming, has in recent years shown us a relentless series of hurricanes, tsunamis, earthquakes, and eruptions killing thousands, turning millions into refugees, and leaving whole cities in shocked, shattered ruins.Of nature's weapons, tornadoes are among the most unforgiving, and here's an unforgettable portrait of these storms and one extraordinary man who challenged them—and produced the first-ever photographs snatched from a rampaging twister's black heart. Tornado chaser Tim Samaras, working with master storyteller Stefan Bechtel, author of Roar of the Heavens, has created a page-turner with narrative force and scientific substance.In the first of five you-are-there accounts, Tornado Hunter opens with a moment-by-moment description of the 2003 catastrophe that engulfed Manchester, South Dakota. The authors evoke the doomed town and its people; the dark menacing funnel; and Samaras's fearless advance into the whirlwind’s core to deploy the ingenious equipment he devised. They interweave the tornado chaser's passion, the fascinating science of the storms themselves, and six decades of progress in predicting and recording their onslaught—an art beholden to Samaras's own groundbreaking inventions.Tim Samaras's 2004 article in National Geographic became one of the most widely read in the magazine’s history. This powerful book is destined to blast its way onto bestseller lists everywhere.

    Dozens of examples in innumeracy show us how it affects not only personal economics and travel plans, but explains mis-chosen mates, inappropriate drug-testing, and the allure of pseudo-science.

    This book focuses on practical algorithms that have been used to solve key problems in data mining and which can be used on even the largest datasets. It begins with a discussion of the map-reduce framework, an important tool for parallelizing algorithms automatically. The authors explain the tricks of locality-sensitive hashing and stream processing algorithms for mining data that arrives too fast for exhaustive processing. The PageRank idea and related tricks for organizing the Web are covered next. Other chapters cover the problems of finding frequent itemsets and clustering. The final chapters cover two applications: recommendation systems and Web advertising, each vital in e-commerce. Written by two authorities in database and Web technologies, this book is essential reading for students and practitioners alike.

    Instead of giving you the most broadly popular result, Google now tries to predict what you are most likely to click on. According to MoveOn.org board president Eli Pariser, Google's change in policy is symptomatic of the most significant shift to take place on the Web in recent years - the rise of personalization. In this groundbreaking investigation of the new hidden Web, Pariser uncovers how this growing trend threatens to control how we consume and share information as a society-and reveals what we can do about it.Though the phenomenon has gone largely undetected until now, personalized filters are sweeping the Web, creating individual universes of information for each of us. Facebook - the primary news source for an increasing number of Americans - prioritizes the links it believes will appeal to you so that if you are a liberal, you can expect to see only progressive links. Even an old-media bastion like "The Washington Post" devotes the top of its home page to a news feed with the links your Facebook friends are sharing. Behind the scenes a burgeoning industry of data companies is tracking your personal information to sell to advertisers, from your political leanings to the color you painted your living room to the hiking boots you just browsed on Zappos.In a personalized world, we will increasingly be typed and fed only news that is pleasant, familiar, and confirms our beliefs - and because these filters are invisible, we won't know what is being hidden from us. Our past interests will determine what we are exposed to in the future, leaving less room for the unexpected encounters that spark creativity, innovation, and the democratic exchange of ideas.While we all worry that the Internet is eroding privacy or shrinking our attention spans, Pariser uncovers a more pernicious and far-reaching trend on the Internet and shows how we can - and must - change course. With vivid detail and remarkable scope, The Filter Bubble reveals how personalization undermines the Internet's original purpose as an open platform for the spread of ideas and could leave us all in an isolated, echoing world.

    Wilson has distilled sixty years of teaching into a book for students, young and old. Reflecting on his coming-of-age in the South as a Boy Scout and a lover of ants and butterflies, Wilson threads these twenty-one letters, each richly illustrated, with autobiographical anecdotes that illuminate his career--both his successes and his failures--and his motivations for becoming a biologist. At a time in human history when our survival is more than ever linked to our understanding of science, Wilson insists that success in the sciences does not depend on mathematical skill, but rather a passion for finding a problem and solving it. From the collapse of stars to the exploration of rain forests and the oceans' depths, Wilson instills a love of the innate creativity of science and a respect for the human being's modest place in the planet's ecosystem in his readers.

    Focusing on the concept of 'relational depth', authors Dave Mearns and Mick Cooper describe a form of encounter in which therapist and client experience profound feelings of contact and engagement with each other and in which the client has an opportunity to explore whatever is experienced as most fundamental to her or his existence.

    It can also be used by English speakers and is a practical, user-friendly book intended as a fast, do-it-yourself guide for those whose English language proficiency is above intermediate. The approach is based on material developed from teaching graduate students at Imperial College London and has been extensively piloted. The book guides the reader through the process of writing science research and will also help with writing a Master's or Doctoral thesis in English.Science writing is much easier than it looks because the structure and language are conventional. The aim of this book is to help the reader discover a template or model for science research writing and then to provide the grammar and vocabulary tools needed to operate that model. There are five units: Introduction, Methodology, Results, Discussion/Conclusion and Abstract. The reader develops a model for each section of the research article through sample texts and exercises; this is followed by a Grammar and Writing Skills section designed to respond to frequently-asked questions as well as a Vocabulary list including examples of how the words and phrases are to be used.

    Self muscle testing is a technique similar to that of applied kinesiology, a technique that people use to gain insight into their own body and mind's healing process. The aim of this book is to empower the reader so that they can begin conducting accurate and reliable self muscle testing as soon as possible.Not all humans have the capacity to accurately self muscle test and this book goes into how to set up the ideal conditions so that this valuable tool can be accessed on a regular and consistent basis. The more people that can successfully self muscle test, the better it is for all beings because muscle testing has the potential to rapidly enhance ones ability to “know thy self.”In this book you will learn about:- The pre-requisites for self muscle testing- How to "Switch on" for accurate testing- How to test without bias- How to test health products, supplements and foods- Some more advanced techniques- and more...

     According to MSNBC, having a child makes you stupid. You actually lose IQ points. Good Morning America has announced that natural blondes will be extinct within two hundred years. Pundits estimated that there were more than a million demonstrators at a tea party rally in Washington, D.C., even though roughly sixty thousand were there. Numbers have peculiar powers-they can disarm skeptics, befuddle journalists, and hoodwink the public into believing almost anything. "Proofiness," as Charles Seife explains in this eye-opening book, is the art of using pure mathematics for impure ends, and he reminds readers that bad mathematics has a dark side. It is used to bring down beloved government officials and to appoint undeserving ones (both Democratic and Republican), to convict the innocent and acquit the guilty, to ruin our economy, and to fix the outcomes of future elections. This penetrating look at the intersection of math and society will appeal to readers of Freakonomics and the books of Malcolm Gladwell.

    The average young person in the UK will spend 10,000 hours gaming by the age of twenty-one. What's causing this mass exodus? According to world-renowned game designer Jane McGonigal the answer is simple: videogames are fulfilling genuine human needs. Drawing on positive psychology, cognitive science and sociology, Reality is Broken shows how game designers have hit on core truths about what makes us happy, and utilized these discoveries to astonishing effect in virtual environments. But why, McGonigal asks, should we use the power of games for escapist entertainment alone? In this groundbreaking exploration of the power and future of gaming, she reveals how gamers have become expert problem solvers and collaborators, and shows how we can use the lessons of game design to socially positive ends, be it in our own lives, our communities or our businesses. Written for gamers and non-gamers alike, Reality is Broken sends a clear and provocative message: the future will belong to those who can understand, design and play games.

    She has managed to achieve this in spite of being diagnosed as schizophrenic and given a "grave" prognosis—and suffering the effects of her illness throughout her life.Saks was only eight, and living an otherwise idyllic childhood in sunny 1960s Miami, when her first symptoms appeared in the form of obsessions and night terrors. But it was not until she reached Oxford University as a Marshall Scholar that her first full-blown episode, complete with voices in her head and terrifying suicidal fantasies, forced her into a psychiatric hospital.Saks would later attend Yale Law School where one night, during her first term, she had a breakdown that left her singing on the roof of the law school library at midnight. She was taken to the emergency room, force-fed antipsychotic medication, and tied hand-and-foot to the cold metal of a hospital bed. She spent the next five months in a psychiatric ward.So began Saks's long war with her own internal demons and the equally powerful forces of stigma. Today she is a chaired professor of law who researches and writes about the rights of the mentally ill. She is married to a wonderful man.In The Center Cannot Hold, Elyn Saks discusses frankly and movingly the paranoia, the inability to tell imaginary fears from real ones, and the voices in her head insisting she do terrible things, as well as the many obstacles she overcame to become the woman she is today. It is destined to become a classic in the genre.
