Then, attempting to break a Nazi code during World War II, he successfully designed and built one, thus ensuring the Allied victory. Turing became a champion of artificial intelligence, but his work was cut short. As an openly gay man at a time when homosexuality was illegal in England, he was convicted and forced to undergo a humiliating "treatment" that may have led to his suicide.With a novelist's sensitivity, David Leavitt portrays Turing in all his humanity—his eccentricities, his brilliance, his fatal candor—and elegantly explains his work and its implications.

    He spent two years gathering information that demonstrates this and along the way interviewed more than a hundred experts in a number of different fields. Among them were parapsychologists, medical doctors, psychologists, psychiatrists, quantum physicists, and researchers into the true nature of reality. Specific examples are presented that indicate what happens when we die, for example that memories can be formed and retained despite a subject’s brain having been shutdown and the blood drained from it. Questions such as whether or not you will be able to communicate with living loved ones after death are addressed, if it is possible to be reborn, and what might be missing from reproductive theory to explain the various phenomena indicated in the many case histories and scientific investigations presented. All of us will someday cross the border to what Shakespeare called "The undiscovered country." As long as we must make that trip, wouldn’t it be smart to find out where we are going and what to expect when we get there?

    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.

    . . like a pendulum? These may not look like math questions, but they are-because they all have to do with patterns. And mathematics, at heart, is the study of patterns. That realization changed Eddie Woo's life-by turning the "dry" subject he dreaded in high school into a boundless quest for discovery. Now an award-winning math teacher, Woo sees patterns everywhere: in the "branches" of blood vessels and lightning, in the growth of a savings account and a sunflower, even in his morning cup of tea! Here are twenty-six bite-size chapters on the hidden mathematical marvels that encrypt our email, enchant our senses, and even keep us alive-from the sine waves we hear as "music" to the mysterious golden ratio. This book will change your mind about what math can be. We are all born mathematicians-and It's a Numberful World.

    It lends to milk cartons the associative richness of Marcel Proust's madeleines. It names the eight most significant advances in a human life -- beginning with shoe-tying. It asks whether the hot air blowers in bathrooms really are more sanitary than towels. And it casts a dazzling light on our relations with the objects and people we usually take for granted.

    The seven-book saga is an excellent primer on spying, intelligence, and politics.

Learn how to break secret codes, gather intelligence, read character's motives, and why Severus Snape is the best double agent ever.

    The seas have risen, the skies have darkened and the American Midwest has become a desert. A handful of corporations own and operate the country and food is used as a means of oppression. The year is 2074. America is now a third-world nation and China, with its prosperous and burgeoning middle class, is the leader of the Free World. Against this backdrop, a devastating raid by the wealthy ruling class on a stronghold of rebels fighting against the system inadvertently unites two enemies in a forbidden love that threatens to tear their worlds apart. Carlin Pheney, a decorated military pilot and member of the upper class, is captured by Aelena Hall, a veteran leader of the food wars. Together, they become fugitives on the run from a military industrial complex headed by Carlin’s father. Aided by strangers and betrayed by friends, they are swept up in an unstoppable global catastrophe. When Aelena is captured and thrown into the Federal Torture Chamber on Guantanamo Island, Carlin devises a desperate plan for her impossible escape from the water-bound prison.
