Most of the time this math works quietly behind the scenes . . . until it doesn't. All sorts of seemingly innocuous mathematical mistakes can have significant consequences.Math is easy to ignore until a misplaced decimal point upends the stock market, a unit conversion error causes a plane to crash, or someone divides by zero and stalls a battleship in the middle of the ocean.Exploring and explaining a litany of glitches, near misses, and mathematical mishaps involving the internet, big data, elections, street signs, lotteries, the Roman Empire, and an Olympic team, Matt Parker uncovers the bizarre ways math trips us up, and what this reveals about its essential place in our world. Getting it wrong has never been more fun.

    His inventions, patents, and theoretical work formed the basis of modern AC electricity, and contributed to the development of radio and television. Like his competitor Thomas Edison, Tesla was one of America's first celebrity scientists, enjoying the company of New York high society and dazzling the likes of Mark Twain with his electrical demonstrations. An astute self-promoter and gifted showman, he cultivated a public image of the eccentric genius. Even at the end of his life when he was living in poverty, Tesla still attracted reporters to his annual birthday interview, regaling them with claims that he had invented a particle-beam weapon capable of bringing down enemy aircraft.Plenty of biographies glamorize Tesla and his eccentricities, but until now none has carefully examined what, how, and why he invented. In this groundbreaking book, W. Bernard Carlson demystifies the legendary inventor, placing him within the cultural and technological context of his time, and focusing on his inventions themselves as well as the creation and maintenance of his celebrity. Drawing on original documents from Tesla's private and public life, Carlson shows how he was an idealist inventor who sought the perfect experimental realization of a great idea or principle, and who skillfully sold his inventions to the public through mythmaking and illusion.This major biography sheds new light on Tesla's visionary approach to invention and the business strategies behind his most important technological breakthroughs.

    And it would be Mike Leinbach who would be a key leader in the search and recovery effort as NASA, FEMA, the FBI, the US Forest Service, and dozens more federal, state, and local agencies combed an area of rural east Texas the size of Rhode Island for every piece of the shuttle and her crew they could find. Assisted by hundreds of volunteers, it would become the largest ground search operation in US history. For the first time, here is the definitive inside story of the Columbia disaster and recovery and the inspiring message it ultimately holds. In the aftermath of tragedy, people and communities came together to help bring home the remains of the crew and nearly 40 percent of shuttle, an effort that was instrumental in piecing together what happened so the shuttle program could return to flight and complete the International Space Station. Bringing Columbia Home shares the deeply personal stories that emerged as NASA employees looked for lost colleagues and searchers overcame immense physical, logistical, and emotional challenges and worked together to accomplish the impossible. Featuring a foreword and epilogue by astronauts Robert Crippen and Eileen Collins, this is an incredible narrative about best of humanity in the darkest of times and about how a failure at the pinnacle of human achievement became a story of cooperation and hope.

    I also hope that it will serve as a useful reference too for the many workers engaged in one type of solid state research activity or another, who may be without formal training in the subject.

    The rotator cuff, a group of four, flat tendons that connect to the critical muscles that stabilize your shoulder, can cause a lot more problems than you might think. Consider a few of these statistics from the published literature: .It's simply just a matter of time until the majority of shoulders get a rotator cuff tear. According to Magnetic Resonance Imaging (MRI) scans, approximately 4% of people under forty years of age have a torn rotator cuff. After age sixty, however, 54% of people have one (Sher 1995). .Once the rotator cuff gets torn, it doesn't look good either. One study followed a group of patients with tears in their rotator cuffs and found that 80% of the them went on to either enlarge or turn into full thickness tears-in less than a two-year period (Yamanaka 1994). As you can tell, rotator cuff problems aren't just for elite athletes. Seriously consider investing just a few minutes a week doing the simple exercises in this book if you: .have been diagnosed with either a partial or full thickness rotator cuff tear (yes, many studies show that even full thickness tears can be helped with exercise!) .experience shoulder pain .do upper body weight lifting .have a job or play a sport where you do a lot of work with your arms above shoulder level .have been diagnosed with "impingement syndrome" .want a healthy and properly functioning rotator cuff So whether you already suffer from a rotator cuff problem, or simply want to prevent one, Treat Your Own Rotator Cuff will guide you step-by-step through an evidence-based program that can iron-plate your shoulders in just minutes a week.

    (It was the heyday of Boss Tweed in New York.) But the Brooklyn Bridge was at once the greatest engineering triumph of the age, a surpassing work of art, a proud American icon, and a story like no other in our history. Courage, chicanery, unprecedented ingenuity and plain blundering, heroes, rascals, all the best and worst in human nature played a part. At the center of the drama were the stricken chief engineer, Washington Roebling and his remarkable wife, Emily Warren Roebling, neither of whom ever gave up in the face of one heartbreaking setback after another. The Great Bridge is a sweeping narrative of a stupendous American achievement that rose up out of its era like a cathedral, a symbol of affirmation then and still in our time.

    The Computer Revolution may be even more life-changing than the Industrial Revolution. We can do things with computers that could never be done before, and computers can do things for us that could never be done before.But our love of computers should not cloud our thinking about their limitations.We are told that computers are smarter than humans and that data mining can identify previously unknown truths, or make discoveries that will revolutionize our lives. Our lives may well be changed, but not necessarily for the better. Computers are very good at discovering patterns, but are uselessin judging whether the unearthed patterns are sensible because computers do not think the way humans think.We fear that super-intelligent machines will decide to protect themselves by enslaving or eliminating humans. But the real danger is not that computers are smarter than us, but that we think computers are smarter than us and, so, trust computers to make important decisions for us.The AI Delusion explains why we should not be intimidated into thinking that computers are infallible, that data-mining is knowledge discovery, and that black boxes should be trusted.
