    Finding these forays both puzzling and exhilarating, Robb dug deeper into the science of dreams at an extremely opportune moment: just as researchers began to understand why dreams exist. They aren’t just random events; they have clear purposes. They help us learn and even overcome psychic trauma. Robb draws on fresh and forgotten research, as well as her experience and that of other dream experts, to show why dreams are vital to our emotional and physical health. She explains how we can remember our dreams better—and why we should. She traces the intricate links between dreaming and creativity, and even offers advice on how we can relish the intense adventure of lucid dreaming for ourselves.Why We Dream is a clear-eyed, cutting-edge examination of the meaning and purpose of our nightly visions and a guide to changing our dream lives—and making our waking lives richer, healthier, and happier.

    There really are no ultimate authority figures-no one has the secret and there is no place to look up the definitive answers to our questions (not even Google). But, by thinking skeptically and logically, we can combat sloppy reasoning, bad arguments and superstitious thinking. It's difficult, and takes a lot of vigilance, but it's worth the effort.In this tie-in to their incredibly popular "The Skeptics Guide to the Universe" podcast, Steven Novella, MD along with "Skeptical Rogues" Bob Novella, Cara Santa Maria, Jay Novella, and Evan Bernstein will explain the tenets of skeptical thinking and debunk some of the biggest scientific myths, fallacies and conspiracy theories (Anti-vaccines, homeopathy, UFO sightings, etc.) They'll help us try to make sense of what seems like an increasingly crazy world using powerful tools like science and philosophy. THE SKEPTICS' GUIDE TO THE UNIVERSE is your guide through this maze of modern life. It covers essential critical thinking skills, as well as giving insight into how your brain works and how to avoid common pitfalls in thinking. They discuss the difference between science and pseudoscience, how to recognize common science news tropes, how to discuss conspiracy theories with that crazy coworker of yours, and how to apply all of this to everyday life.So, are you ready to join them on an epic scientific quest, one that has taken us from huddling in dark caves to stepping foot on the Moon? (Yes, we really did that.) Like all adventures, this one is foremost a journey of self discovery. The monsters you will slay and challenges you will face are mostly constructs of your own mind. With the SKEPTIC'S GUIDE TO THE UNIVERSE, we can do this together.

    At thirty years old, Gabriel Wyner speaks six languages fluently.  He didn’t learn them in school -- who does? -- rather, he learned them in the past few years, working on his own and practicing on the subway, using simple techniques and free online resources. In Fluent Forever Wyner reveals what he’s discovered.   The greatest challenge to learning a foreign language is the challenge of memory; there are just too many words and too many rules. For every new word we learn, we seem to forget two old ones, and as a result, fluency can seem out of reach. Fluent Forever tackles this challenge head-on. With empathy for the language-challenged and abundant humor, Wyner deconstructs the learning process, revealing how to build a foreign language in your mind from the ground up.  Starting with pronunciation, you’ll learn how to rewire your ears and turn foreign sounds into familiar sounds. You'll retrain your tongue to produce those sounds accurately, using tricks from opera singers and actors. Next, you'll begin to tackle words, and connect sounds and spellings to imagery, rather than translations, which will enable you to think in a foreign language.  And with the help of sophisticated spaced-repetition techniques, you'll be able to memorize hundreds of words a month in minutes every day. Soon, you'll gain the ability to learn grammar and more difficult abstract words--without the tedious drills and exercises of language classes and grammar books.  This is brain hacking at its most exciting, taking what we know about neuroscience and linguistics and using it to create the most efficient and enjoyable way to learn a foreign language in the spare minutes of your day.

    Exceptional Coverage. This authoritative volume starts with a clear introduction to the animal world, examining the reasons for the apparently infinite variety of animal forms and major evolutionary developments. Animal anatomy, life cycles and the principles of classification are also explored. This is followed by a superbly illustrated survey of world habitats, showing how they have adapted to each environment, and the threats that face both wildlife and plants today. The main part of the book, an up-to-date and comprehensive animal catalog, looks in detail at each major group and provides fascinating profiles of over 2,000 individual species. Visually Breathtaking. Spectacular photographic portraits bring a vast array of animals vividly to life, with special features on well-known and important animals such as the Galapagos tortoise. Each species profile is supported by maps and symbols showing distribution and habitat, as well as key information on size, population, and conservation status, forming an invaluable reference database. Outstanding Reference. Clear, comprehensive, and thought provoking, the Smithsonian Animal is essential reading for wildlife enthusiasts of all ages and levels of experience.

    But for the past thirty-five years of his professional life, he has also been active as an investigator of the paranormal, occult, and supernatural claims that have impressed the thinking of the public for a generation: ESP, psychokinesis, psychic detectives, levitation, psychic surgery, UFOs, dowsing, astrology, and many others. Those of us unable to discriminate between geniune scientific research and the pseudoscientific nonsense that has resulted in fantastic theories and fancies have long needed James Randi and Flim-Flam!In this book, Randi explores and exposes what he believes to be the outrageous deception that has been promoted widely in the media. Unafraid to call researchers to account for their failures and impostures, Randi tells us that we have been badly served by scientists who have failed to follow the procedures required by their training and traditions. Here he shows us how what he views as sloppy research has been followed by rationalizations of evident failures, and we see these errors and misrepresentations clearly pointed out. Mr. Randi provides us with a compelling and convincing document that will certainly startle and enlighten all who read it.

    Filled with surprising stories of accidental genius and brilliant mistakes—from the French publisher who invented the phonograph before Edison but forgot to include playback, to the Hollywood movie star who helped invent the technology behind Wi-Fi and Bluetooth—How We Got to Now investigates the secret history behind the everyday objects of contemporary life. In his trademark style, Johnson examines unexpected connections between seemingly unrelated fields: how the invention of air-conditioning enabled the largest migration of human beings in the history of the species—to cities such as Dubai or Phoenix, which would otherwise be virtually uninhabitable; how pendulum clocks helped trigger the industrial revolution; and how clean water made it possible to manufacture computer chips. Accompanied by a major six-part television series on PBS, How We Got to Now is the story of collaborative networks building the modern world, written in the provocative, informative, and engaging style that has earned Johnson fans around the globe.
