Excerpt: The Man Who Mistook His Wife for a Hat and Other Clinical Tales is a 1985 book by neurologist Oliver Sacks describing the case histories of some of his patients. The title of the book comes from the case study of a man with visual agnosia. The Man Who Mistook His Wife for a Hat became the basis of an opera of the same name by Michael Nyman, which premiered in 1986. The book comprises 24 essays split into 4 sections which each deal with a particular aspect of brain function such as deficits and excesses in the first two sections (with particular emphasis on the right hemisphere of the brain) while the third and fourth describe phenomenological manifestations with reference to spontaneous reminiscences, altered perceptions, and extraordinary qualities of mind found in "retardates." The individual essays in this book include, but are not limited to: Christopher Rawlence wrote the libretto for a chamber opera, directed by Michael Morris with music by Michael Nyman, based on the title story. "The Man Who Mistook His Wife for a Hat" was first produced by the Institute of Contemporary Arts in London in 1986. A television version of the opera was subsequently broadcast in the UK. Peter Brook adapted Sacks's book into an acclaimed theatrical production, "L'Homme Qui...," which premiered at the Theatre des Bouffes du Nord, Paris, in 1993. An Indian theatre company, performed a play The Blue Mug, based on the book, starring Rajat Kapoor, Konkona Sen Sharma, Ranvir Shorey a...More: http: //booksllc.net/?id=3371

    But his heart was failing. After months of waiting for a heart transplant, he died during the operation. Hours after his death, his wife Susan was asked a shocking question: would she donate her husband’s face to a total stranger?The stranger was James Maki, the adopted son of parents who spent part of World War II in an internment camp for Japanese Americans. Rebelling against his stern father, a professor, by enlisting to serve in Vietnam, he returned home a broken man, addicted to drugs. One night he fell facedown onto the electrified third rail of a Boston subway track.A young Czech surgeon who was determined to make a better life on the other side of the Iron Curtain was on call when the ambulance brought Maki to the hospital. Although Dr. Bohdan Pomahac gave him little chance of survival, Maki battled back. He was sober and grateful for a second chance, but he became a recluse, a man without a face. His only hope was a controversial face transplant, and Dr. Pomahac made it happen.In The Match, Susan Whitman Helfgot captures decades of drama and history, taking us from Warsaw to Japan, from New York to Hollywood. Through wars and immigration, poverty and persecution, from a medieval cadaver dissection to a stunning seventeen-hour face transplant, she weaves together the story of people forever intertwined—a triumphant legacy of hope.

    More than any other language, Python was created with the philosophy of simplicity and parsimony. Now 25 years old, Python has become the primary or secondary language (after SQL) for many business users. With popularity comes diversity--and possibly dilution.This guide, collaboratively written by over a hundred members of the Python community, describes best practices currently used by package and application developers. Unlike other books for this audience, The Hitchhiker's Guide is light on reusable code and heavier on design philosophy, directing the reader to excellent sources that already exist.

    It's aimed at developers who might not be quite comfortable with the idea of pointers and static typing.http://openmymind.net/The-Little-Go-B...

    Every complete program uses a consistent style, and as programs are analyzed, styles and standards are further explained. Whenever possible, the authors develop the principle of a subject before they introduce the language implementation so the student understands the concept before dealing with the nuances of C++. In addition, a vast array of figures and tables visually reinforce key concepts. By integrating software engineering principles and encouraging the student to resist the temptation to immediately code, the text builds a solid foundation in problem solving.

    He did not crave my company, cling to and cuddle me endlessly. He showed no need to bond with me, his father, and we did not. He exhausted me, he frustrated me and he scared me. I came to dread coming home from work sometimes, or those moments when it was my turn to wrestle him into bed and begin the long struggle to settle him. I said things that will forever haunt me, like “What is wrong with that child?” and “Is he always going to be this annoying?” What I didn't know then was that he was autistic.When that realisation came, so did the beginning of my mission to understand my son, and to understand autism. This book chronicles that search for understanding and answers. It documents one parent’s attempts to come to terms with, and accept, his child. It is raw and real, sometimes confused and frightened but also, I’d like to think, written with warmth and love and an ability to smile through difficult times.This book is for anyone starting out on a pathway with their child that they did not expect. It’s also for people who, like me, are a little further down that road but still learning, still asking questions and still getting it wrong sometimes. You are not alone.

    But in the scalp of a balding man, they do not get everything they need and as a result, the hair-producing cells gradually die off. Here we have an example of a mild ‘disease’ which is caused by cellular malnutrition.” —Dr. Roger J. Williams “A living cell requires energy not only for all of its functions, but also for maintenance of its structure.” —Nobel Laureate Albert Szent-Györgyi "What could be more important to understand than biological energy? Thought, growth, movement, every philosophical and practical issue involves the nature of biological energy.” —Raymond Peat, PhD ======== The Current View of Pattern Hair Loss is Unproductive (and Dangerous) While it is often stated with great confidence that pattern pattern hair loss is the result of defective genes and "male" androgenic hormones (e.g., dihydrotestosterone or DHT), the theory is physiologically unsound. After 60 years of research the "genetic-androgen" hypoheses has produced a single FDA-approved "therapy" that works less than 50% the time and can result in permanent chemical castration (Minoxidil is a nonstarter for many men and women). In contrast, castrates and pseudohermaphrodites--who serve as the foundation for all baldness research--are protected from pattern hair loss 100% of the time. Steps Towards a 'Bioenergetic' View of Pattern Hair Loss Standing on the shoulders of giants (e.g., Otto Warburg, Albert Szent-Györgyi, Gilbert Ling, Ray Peat and others), HAIR LIKE A FOX sets up an alternative 'bioenergetic model' of pattern hair loss with a focus on the smallest unit of life, the cell. This same context elucidates simple yet effective therapies for halting and perhaps reversing pattern hair loss in a way that harmonizes with our unique physiology.
