Download or read book Vagrancy in Birds written by Alexander Lees and published by Princeton University Press. This book was released on 2022-02-15 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: An exploration of the causes and patterns of avian vagrancy Avian vagrancy—the appearance of birds outside of their expected habitat—is a phenomenon that has fascinated natural historians for centuries, from Victorian collectors willing to spend fortunes on a rare specimen to today’s bird-chasing “twitchers.” Yet despite the obsessions of countless ornithologists, what do we actually know about the enigma of vagrancy? In Vagrancy in Birds, Alexander Lees and James Gilroy explore the causes, patterns, and processes behind the occurrences of these unique birds. Lees and Gilroy draw on recent research to answer fundamental questions: What causes avian vagrancy? Why do some places attract so many vagrant birds? Why are some species more predisposed to long-range vagrancy than others? The authors present readers with everything known about the subject, and bring together different lines of evidence to make the case for vagrancy as a biological phenomenon with important implications for avian ecology and evolution. Filled with a wealth of photographs, Vagrancy in Birds will fascinate avian enthusiasts everywhere.

Download or read book The Day of the Triffids written by John Wyndham and published by Rosetta Books. This book was released on 2010-07-01 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: The classic postapocalyptic thriller with “all the reality of a vividly realized nightmare” (The Times, London). Triffids are odd, interesting little plants that grow in everyone’s garden. Triffids are no more than mere curiosities—until an event occurs that alters human life forever. What seems to be a spectacular meteor shower turns into a bizarre, green inferno that blinds everyone and renders humankind helpless. What follows is even stranger: spores from the inferno cause the triffids to suddenly take on a life of their own. They become large, crawling vegetation, with the ability to uproot and roam about the country, attacking humans and inflicting pain and agony. William Masen somehow managed to escape being blinded in the inferno, and now after leaving the hospital, he is one of the few survivors who can see. And he may be the only one who can save his species from chaos and eventual extinction . . . With more than a million copies sold, The Day of the Triffids is a landmark of speculative fiction, and “an outstanding and entertaining novel” (Library Journal). “A thoroughly English apocalypse, it rivals H. G. Wells in conveying how the everyday invaded by the alien would feel. No wonder Stephen King admires Wyndham so much.” —Ramsey Campbell, author of The Overnight “One of my all-time favorite novels. It’s absolutely convincing, full of little telling details, and that sweet, warm sensation of horror and mystery.” —Joe R. Lansdale, author of Edge of Dark Water

Download or read book Fire in the Valley written by Michael Swaine and published by Pragmatic Bookshelf. This book was released on 2014-10-20 with total page 602 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the 1970s, while their contemporaries were protesting the computer as a tool of dehumanization and oppression, a motley collection of college dropouts, hippies, and electronics fanatics were engaged in something much more subversive. Obsessed with the idea of getting computer power into their own hands, they launched from their garages a hobbyist movement that grew into an industry, and ultimately a social and technological revolution. What they did was invent the personal computer: not just a new device, but a watershed in the relationship between man and machine. This is their story. Fire in the Valley is the definitive history of the personal computer, drawn from interviews with the people who made it happen, written by two veteran computer writers who were there from the start. Working at InfoWorld in the early 1980s, Swaine and Freiberger daily rubbed elbows with people like Steve Jobs and Bill Gates when they were creating the personal computer revolution. A rich story of colorful individuals, Fire in the Valley profiles these unlikely revolutionaries and entrepreneurs, such as Ed Roberts of MITS, Lee Felsenstein at Processor Technology, and Jack Tramiel of Commodore, as well as Jobs and Gates in all the innocence of their formative years. This completely revised and expanded third edition brings the story to its completion, chronicling the end of the personal computer revolution and the beginning of the post-PC era. It covers the departure from the stage of major players with the deaths of Steve Jobs and Douglas Engelbart and the retirements of Bill Gates and Steve Ballmer; the shift away from the PC to the cloud and portable devices; and what the end of the PC era means for issues such as personal freedom and power, and open source vs. proprietary software.

Download or read book The Emperor of All Maladies written by Siddhartha Mukherjee and published by Simon and Schuster. This book was released on 2011-08-09 with total page 624 pages. Available in PDF, EPUB and Kindle. Book excerpt: Winner of the Pulitzer Prize and a documentary from Ken Burns on PBS, this New York Times bestseller is “an extraordinary achievement” (The New Yorker)—a magnificent, profoundly humane “biography” of cancer—from its first documented appearances thousands of years ago through the epic battles in the twentieth century to cure, control, and conquer it to a radical new understanding of its essence. Physician, researcher, and award-winning science writer, Siddhartha Mukherjee examines cancer with a cellular biologist’s precision, a historian’s perspective, and a biographer’s passion. The result is an astonishingly lucid and eloquent chronicle of a disease humans have lived with—and perished from—for more than five thousand years. The story of cancer is a story of human ingenuity, resilience, and perseverance, but also of hubris, paternalism, and misperception. Mukherjee recounts centuries of discoveries, setbacks, victories, and deaths, told through the eyes of his predecessors and peers, training their wits against an infinitely resourceful adversary that, just three decades ago, was thought to be easily vanquished in an all-out “war against cancer.” The book reads like a literary thriller with cancer as the protagonist. Riveting, urgent, and surprising, The Emperor of All Maladies provides a fascinating glimpse into the future of cancer treatments. It is an illuminating book that provides hope and clarity to those seeking to demystify cancer.

Download or read book How to Change Your Mind written by Michael Pollan and published by Penguin. This book was released on 2018-05-15 with total page 481 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Pollan keeps you turning the pages . . . cleareyed and assured.” —New York Times A #1 New York Times Bestseller, New York Times Book Review 10 Best Books of 2018, and New York Times Notable Book A brilliant and brave investigation into the medical and scientific revolution taking place around psychedelic drugs--and the spellbinding story of his own life-changing psychedelic experiences When Michael Pollan set out to research how LSD and psilocybin (the active ingredient in magic mushrooms) are being used to provide relief to people suffering from difficult-to-treat conditions such as depression, addiction and anxiety, he did not intend to write what is undoubtedly his most personal book. But upon discovering how these remarkable substances are improving the lives not only of the mentally ill but also of healthy people coming to grips with the challenges of everyday life, he decided to explore the landscape of the mind in the first person as well as the third. Thus began a singular adventure into various altered states of consciousness, along with a dive deep into both the latest brain science and the thriving underground community of psychedelic therapists. Pollan sifts the historical record to separate the truth about these mysterious drugs from the myths that have surrounded them since the 1960s, when a handful of psychedelic evangelists inadvertently catalyzed a powerful backlash against what was then a promising field of research. A unique and elegant blend of science, memoir, travel writing, history, and medicine, How to Change Your Mind is a triumph of participatory journalism. By turns dazzling and edifying, it is the gripping account of a journey to an exciting and unexpected new frontier in our understanding of the mind, the self, and our place in the world. The true subject of Pollan's "mental travelogue" is not just psychedelic drugs but also the eternal puzzle of human consciousness and how, in a world that offers us both suffering and joy, we can do our best to be fully present and find meaning in our lives.

Available in PDF, EPUB and Kindle. Book excerpt: The landmark self-help bestseller that has inspired and enhanced the lives of more than 30 million readers. In this updated edition, with a new introduction and editorial commentary by Matt Furey, president of the Psycho-Cybernetics Foundation, the original 1960 text has been annotated and amplified to make Maxwell Maltz's message even more relevant for the contemporary reader. Maltz was the first researcher and author to explain how the self-image (a term he popularized) has complete control over an individual's ability to achieve, or fail to achieve, any goal. He developed techniques for improving and managing self-image visualization, mental rehearsal and relaxation which have informed and inspired countless motivational gurus, sports psychologists, and self-help practitioners for more than sixty years. Rooted in solid science, the classic teachings in Psycho-Cybernetics continue to provide a prescription for thinking and acting that lead to life-enhancing, quantifiable results.

Available in PDF, EPUB and Kindle. Book excerpt: Beloved, best-selling science writer Mary Roach’s “acutely entertaining, morbidly fascinating” (Susan Adams, Forbes) classic, now with a new epilogue. For two thousand years, cadavers – some willingly, some unwittingly – have been involved in science’s boldest strides and weirdest undertakings. They’ve tested France’s first guillotines, ridden the NASA Space Shuttle, been crucified in a Parisian laboratory to test the authenticity of the Shroud of Turin, and helped solve the mystery of TWA Flight 800. For every new surgical procedure, from heart transplants to gender confirmation surgery, cadavers have helped make history in their quiet way. “Delightful—though never disrespectful” (Les Simpson, Time Out New York), Stiff investigates the strange lives of our bodies postmortem and answers the question: What should we do after we die? “This quirky, funny read offers perspective and insight about life, death and the medical profession. . . . You can close this book with an appreciation of the miracle that the human body really is.” —Tara Parker-Pope, Wall Street Journal “Gross, educational, and unexpectedly sidesplitting.” —Entertainment Weekly

Available in PDF, EPUB and Kindle. Book excerpt: We live in a fast-paced, busy world, and many of us are stressed out and anxious as a result. If you suffer from anxiety but have found little relief from modern western treatments, or if you are looking for complimentary treatment, the ancient practice of qigong—which can be understood as the cultivation of internal energy—may offer you relief. Qigong is rooted in Chinese philosophy and medicine, and it utilizes breathing, movement, and awareness exercises to promote healing and aid in meditation. In The Qigong Workbook for Anxiety, world-renowned and respected qigong master Kam Chuen Lam presents the first workbook for overcoming anxiety problems utilizing traditional Chinese energy-focusing exercises. By following these simple and accessible step-by-step exercises, readers will learn to transform feelings of anxiety into resilience and inner strength. The workbook also contains helpful illustrations to help you carry out these exercises. In the book, Lam will help you think about anxiety, and yourself, in a different way—as a whole. You’ll also learn to stop resisting moments of anxiety and other strong emotions, but rather to embrace them within the larger flow of your body’s energy field. By doing this, you will ultimately strengthen and cultivate the natural energy you possess. Author Kam Chuen Lam has been a traditional Chinese healer for over forty years, and is an internationally respected authority on the Chinese health systems of Chi Kung and Tai Chi.
