    In addition to explaining the basic moves, this book provides writing templates that show students explicitly how to make these moves in their own writing.

      Since taking over TED in the early 2000s, Chris Anderson has shown how carefully crafted short talks can be the key to unlocking empathy, stirring excitement, spreading knowledge, and promoting a shared dream. Done right, a talk can electrify a room and transform an audience’s worldview. Done right, a talk is more powerful than anything in written form.         This book explains how the miracle of powerful public speaking is achieved, and equips you to give it your best shot. There is no set formula; no two talks should be the same. The goal is for you to give the talk that only you can give. But don’t be intimidated. You may find it more natural than you think.         Chris Anderson has worked behind the scenes with all the TED speakers who have inspired us the most, and here he shares insights from such favorites as Sir Ken Robinson, Amy Cuddy, Bill Gates, Elizabeth Gilbert, Salman Khan, Dan Gilbert, Mary Roach, Matt Ridley, and dozens more — everything from how to craft your talk’s content to how you can be most effective on stage. This is the 21st-century’s new manual for truly effective communication and it is a must-read for anyone who is ready to create impact with their ideas.

    And yet, disturbingly, in today's so-called information age, pseudoscience is burgeoning with stories of alien abduction, channeling past lives, and communal hallucinations commanding growing attention and respect. As Sagan demonstrates with lucid eloquence, the siren song of unreason is not just a cultural wrong turn but a dangerous plunge into darkness that threatens our most basic freedoms.

    . . on childhood. As the pace of life accelerates to hyperspeed–with too much stuff, too many choices, and too little time–children feel the pressure. They can become anxious, have trouble with friends and school, or even be diagnosed with behavioral problems. Now, in defense of the extraordinary power of less, internationally renowned family consultant Kim John Payne helps parents reclaim for their children the space and freedom that all kids need, allowing their children’s attention to focus and their individuality to flourish.Based on Payne’s twenty year’s experience successfully counseling busy families, Simplicity Parenting teaches parents how to worry and hover less–and how to enjoy more. For those who want to slow their children’s lives down but don’t know where to start, Payne offers both inspiration and a blueprint for change.• Streamline your home environment. The average child has more than 150 toys. Here are tips for reducing the amount of toys, books, and clutter–as well as the lights, sounds, and general sensory overload that crowd the space young imaginations need in order to grow.• Establish rhythms and rituals. Predictability (routines) and transparency (knowing the day’s plan) are soothing pressure valves for children. Here are ways to ease daily tensions, create battle-free mealtimes and bedtimes, and tell if your child is overwhelmed.• Schedule a break in the schedule. Too many activities may limit children’s ability to motivate and direct themselves. Learn how to establish intervals of calm in your child’s daily torrent of constant doing–and familiarize yourself with the pros and cons of organized sports and other “enrichment” activities.• Scale back on media and parental involvement. Back out of hyperparenting by managing your children’s “screen time” to limit the endless and sometimes scary deluge of information and stimulation. Parental hovering is really about anxiety; by doing less and trusting more, parents can create a sanctuary that nurtures children’s identity, well-being, and resiliency as they grow–slowly–into themselves. A manifesto for protecting the grace of childhood, Simplicity Parenting is an eloquent guide to bringing new rhythms to bear on the lifelong art of parenting.

    His aim is to present calculus as the first real encounter with mathematics: it is the place to learn how logical reasoning combined with fundamental concepts can be developed into a rigorous mathematical theory rather than a bunch of tools and techniques learned by rote. Since analysis is a subject students traditionally find difficult to grasp, Spivak provides leisurely explanations, a profusion of examples, a wide range of exercises and plenty of illustrations in an easy-going approach that enlightens difficult concepts and rewards effort. Calculus will continue to be regarded as a modern classic, ideal for honours students and mathematics majors, who seek an alternative to doorstop textbooks on calculus, and the more formidable introductions to real analysis.

    In Why Sh*t Happens, esteemed British scientist Peter J. Bentley takes readers on an informative and amusing tour through the least lucky, most accident-prone day of their lives. From sleeping through the alarm clock and burning breakfast to getting caught in the rain and navigating a slippery road, Bentley brilliantly explores disaster and mishap on a molecular level. In the process, he explains the science behind each accident, arming readers with the knowledge to understand what went wrong and how they can steer clear of future harm. Science is respected, trusted, and according to Bentley, largely misunderstood. Why Sh*t Happens urges readers to arm themselves with the power of science in order to better understand the world around them. When a car engine is damaged by the wrong gasoline or a computer is attacked by a virus, science is not to blame, but rather can provide an explanation of what happened. In a text that exudes charm and wit, Bentley reveals the causes behind a wide spectrum of mishaps, including why that razor nick won't stop bleeding, why metal sparks in the microwave, what makes chewing gum stick in hair, and why milk tastes sour when it goes bad. Sh*t will always happen, but now readers will know exactly why. Enter, if you dare, the world of everyday disasters.
