    Italian investigative journalist Paola Leopizzi Harris and French-born information scientist Dr. Jacques F. Vallée have teamed up to uncover the details of a New Mexico crash in 1945, fully two years before the well-known incident at Roswell and the famous sighting by pilot Kenneth Arnold in 1947.Over several site investigation surveys Harris and Vallée reconstructed the historic observations by three witnesses, two of whom are still living, who described to them the circumstances of the crash, with details of the recovery of a nearly-intact flying vehicle and its occupants by an Army detachment. Combining their long experience in field research around the world, the authors have documented the step-by-step efforts by the military to remove the object, an avocado-shaped craft weighting several tons, from the property where it crash-landed during a storm.Surprisingly, the literature of the field only includes a few passing mentions about the case, and only one (foreign) TV documentary has mentioned it, but the correlation between the crash of the extraordinary object and the explosion of the first atom bomb at White Sands, less than 20 miles away, has been missed. Harris and Vallée suggest that the correlation is significant for physical, geographic and biological reasons, quite apart from the obvious strategic implications.The witnesses were able to observe not only the actual crash of the object on their property but every step of the military efforts to lift it and take it away. Fearing retaliation, they remained silent for some 60 years about what they had seen and done over those nine days at the site while the recovery was proceeding. When placed in the context of the history of chemical and physical analysis of retrieved UFO debris--an area where Harris and Vallée have long collaborated—the devices observed by the witnesses raise a number of very important scientific questions.The Honorable Paul Hellyer, former Minister of National Defence of Canada, has stated: “Paola Harris and Jacques Vallée have spent much effort doing field research on location (…) It is now time that their discovery be revealed to the world.”Christopher Mellon, former deputy Assistant Secretary of Defense, called the data “fresh reason to believe that our government is concealing physical proof of alien technology. Read the book, and if persuaded, join the millions of other Americans seeking a straight answer.”And Professor Paul Hynek added that the research “reveals a new UFO history.”

    Utilizing the theme that human cognition has evolved over time as a means of adapting to our environment, Sternberg explores the basics of cognitive psychology through its coverage of cognitive neuroscience, attention and consciousness, perception, memory, knowledge representation, language, problem solving and creativity, decision making and reasoning, cognitive development, and intelligence. Sternberg provides the most comprehensive coverage of any cognitive psychology text available; a "from lab to life" approach covering theory, lab and field research, and applications to everyday life (like driving while talking on a cell phone and airport security).

    As pioneers, inventors, and dreamers have always known, you can do anything if only you persevere. Ever since we hauled ourselves out of the swamp, our history has been one of extraordinary cultural and technological progress, of mind-boggling discoveries and remarkable achievements, often against the odds. It's no coincidence that you see no statues of pessimists in city squares.Still, cynical and doubting voices are heard all too loudly and frequently in public discourse. A potent antidote to their gloom and doom, "The Optimist's Handbook" is a joyful explosion of wit and wisdom from our past and present that celebrates the art of greeting life with the excitement it deserves. This handbook will inspire, enchant, and entertain you as you go forward into all your wonderful tomorrows. Even if, after reading it, you are not moved to feats of glory for the greater good, the fact is that optimists are healthier, happier, and richer than their gloomy counterparts. Hear that, killjoys?"The world is a grindstone and life is your nose."Fred Allen, 1894-1956, American humoristWhy beat around the bush? The truth is that life is a never-ending cycle of toil and pain with nothing but death to reward all our suffering. Furthermore, what solace is there in blind optimism or fanciful daydreaming when it is perfectly clear that the world is heading toward a complete meltdown whether we live in it or not? Resigning yourself to life's grim treadmill, and thereby avoiding more disappointments, is the best way to trudge forward."The Pessimist's Handbook" is an indispensable companion on your journey through this vale of tears. A clear-sighted, realistic look at life's obstacles, this guidebook is stocked with the pearls of wisdom you need to counter the irritating voices of those who trumpet futile positivity and inane confidence in a brighter future. Feel reassured that scores of people share your sense of impending doom...and have done so for centuries. After all, misery loves company, but not when it's a horde of perky utopians.

    Covering every disorder routinely encountered in clinical practice, Frances provides the appropriate ICD-9-CM code for each one (the same code utilized in the DSM), a useful screening question, a colorful descriptive prototype, lucid diagnostic tips, and a discussion of other disorders that must be ruled out. The book closes with an index of the most common presenting symptoms, listing possible diagnoses that must be considered for each. Frances was instrumental in the development of past editions of the DSM and provides helpful cautions on questionable aspects of DSM-5.

    

    Yet you'd have to fly every day for the next 26,000 years to assure yourself of dying in a crash. A leisurely canoe ride is more than 100 times deadlier. Think city streets are unsafe? You're more likely to come to harm in your own home, where every year you stand a 1 in 650 chance of being injured by your bed, mattress, or pillows—and each year 800 Americans die in accidents involving soft furnishings.We live in a world governed by fear, where packets of peanuts "may contain nuts" and children must be ever on the alert to "stranger danger." And yet, life expectancy has never been higher. Crime rates have plunged. Even unintentional injuries are down. So if we're so safe, why are we so afraid?How to Live Dangerously is a hilarious, straight-talking look at the things that terrify us. It considers life's real risks, not to mention the often ridiculous methods we've contrived to keep ourselves "safe." It encourages you to ignore fearmongers and embrace a new kind of freedom, in which we all worry a little less—and live a whole lot more.

    By investing some of the lesser-known corners of psychology, neuroscience, physics, history, and even crime, all through the lens of trickery and illusion, Fooling Houdini arrives at a host of startling revelations about how the mind works--and why, sometimes, it doesn’t.

    To reach this unique audience, Whitlock and Schluter motivate learning with interesting biological and medical examples; they emphasize intuitive understanding; and they focus on real data. The book covers basic topics in introductory statistics, including graphs, confidence intervals, hypothesis testing, comparison of means, regression, and designing experiments. It also introduces the principles behind such modern topics as likelihood, linear models, meta-analysis and computer-intensive methods. Instructors and students consistently praise the book's clear and engaging writing, strong visualization techniques, and its variety of fascinating and relevant biological examples.

    Among the old chestnuts he cracks wide open are the following classics: Knights and knaves The monk and the mountain The dominoes and the chessboard The unexpected hanging The Tower of HanoiUsing real-world analogies, infectious humor, and a fresh approach, this deceptively simple volume will challenge, amuse, enlighten, and surprise even the most experienced puzzle solver.
