Breaking down the symbols themselves, they pose a series of questions: What is energy? What is mass? What has the speed of light got to do with energy and mass? In answering these questions, they take us to the site of one of the largest scientific experiments ever conducted. Lying beneath the city of Geneva, straddling the Franco-Swiss boarder, is a 27 km particle accelerator, known as the Large Hadron Collider. Using this gigantic machine—which can recreate conditions in the early Universe fractions of a second after the Big Bang—Cox and Forshaw will describe the current theory behind the origin of mass.Alongside questions of energy and mass, they will consider the third, and perhaps, most intriguing element of the equation: 'c' - or the speed of light. Why is it that the speed of light is the exchange rate? Answering this question is at the heart of the investigation as the authors demonstrate how, in order to truly understand why E=mc2, we first must understand why we must move forward in time and not backwards and how objects in our 3-dimensional world actually move in 4-dimensional space-time. In other words, how the very fabric of our world is constructed. A collaboration between two of the youngest professors in the UK, Why Does E=mc2? promises to be one of the most exciting and accessible explanations of the theory of relativity in recent years.

    Python is considered easy to learn, but there's no quicker way to mastery of the language than learning from an expert teacher. This edition of "Learning Python" puts you in the hands of two expert teachers, Mark Lutz and David Ascher, whose friendly, well-structured prose has guided many a programmer to proficiency with the language. "Learning Python," Second Edition, offers programmers a comprehensive learning tool for Python and object-oriented programming. Thoroughly updated for the numerous language and class presentation changes that have taken place since the release of the first edition in 1999, this guide introduces the basic elements of the latest release of Python 2.3 and covers new features, such as list comprehensions, nested scopes, and iterators/generators. Beyond language features, this edition of "Learning Python" also includes new context for less-experienced programmers, including fresh overviews of object-oriented programming and dynamic typing, new discussions of program launch and configuration options, new coverage of documentation sources, and more. There are also new use cases throughout to make the application of language features more concrete. The first part of "Learning Python" gives programmers all the information they'll need to understand and construct programs in the Python language, including types, operators, statements, classes, functions, modules and exceptions. The authors then present more advanced material, showing how Python performs common tasks by offering real applications and the libraries available for those applications. Each chapter ends with a series of exercises that will test your Python skills and measure your understanding."Learning Python," Second Edition is a self-paced book that allows readers to focus on the core Python language in depth. As you work through the book, you'll gain a deep and complete understanding of the Python language that will help you to understand the larger application-level examples that you'll encounter on your own. If you're interested in learning Python--and want to do so quickly and efficiently--then "Learning Python," Second Edition is your best choice.

    Nine months later, LeMond lay in a hospital bed, his life in peril after a hunting accident, his career as a bicycle racer seemingly over. And yet, barely two years after this crisis, LeMond mounted a comeback almost without parallel in professional sports. In summer 1989, he again won the Tour—arguably the world’s most grueling athletic contest—by the almost impossibly narrow margin of 8 seconds over another French legend, Laurent Fignon. It remains the closest Tour de France in history.The Comeback chronicles the life of one of America’s greatest athletes, from his roots in Nevada and California to the heights of global fame, to a falling out with his own family and a calamitous confrontation with Lance Armstrong over allegations the latter was doping—a campaign LeMond would wage on principle for more than a decade before Armstrong was finally stripped of his own Tour titles. With the kind of narrative drive that propels books like Moneyball, and a fierce attention to detail, Daniel de Visé reveals the dramatic, ultra-competitive inner world of a sport rarely glimpsed up close, and builds a compelling case for LeMond as its great American hero.

    Consumer's identities are being stolen, and a person's every step is being tracked and stored. What once might have been dismissed as paranoia is now a hard truth, and privacy is a luxury few can afford or understand.In this explosive yet practical book, Kevin Mitnick illustrates what is happening without your knowledge--and he teaches you "the art of invisibility." Mitnick is the world's most famous--and formerly the Most Wanted--computer hacker. He has hacked into some of the country's most powerful and seemingly impenetrable agencies and companies, and at one point he was on a three-year run from the FBI. Now, though, Mitnick is reformed and is widely regarded as the expert on the subject of computer security. He knows exactly how vulnerabilities can be exploited and just what to do to prevent that from happening. In THE ART OF INVISIBILITY Mitnick provides both online and real life tactics and inexpensive methods to protect you and your family, in easy step-by-step instructions. He even talks about more advanced "elite" techniques, which, if used properly, can maximize your privacy. Invisibility isn't just for superheroes--privacy is a power you deserve and need in this modern age.

    This work features Europe's 50 greatest cycling climbs specially selected as scenes of sporting heroism, marvels of nature, spiritual places of pilgrimage that every bike rider or fan wishes to one day visit and conquer.

    Now cyclist and journalist Chris Sidwells brings the Tour to life by pulling back the curtain on the behind-the-scenes battles, tactics, and technology that have played such a large role in the race from its inception.

    From his early years as a keen cyclist in his hometown in Colorado to his unflinching rite of passage as a professional rider with US Postal to his elevation as one of cycling's most resilient, ethical and intelligent team bosses, the highs and lows of his career have mirrored those of the sport itself. Vaughters has had a front-row seat for most of the major events in cycling over the past three decades. He was both a former teammate of Lance and a leading witness against him. And he went on to renounce doping and start the first pro cycling team to dedicate itself to clean riding, which has grown into one of the most successful teams competing today and started a movement that has swept across the sport.This is also not simply a story of races won and lost: Vaughters shows readers how he navigated the complex, international business of building Slipstream into a world-class cycling team. Over the past decade, he has led the sport out of the scandal-plagued Armstrong era. By presenting the world with a team made of talented racers built around a rigorous approach to clean racing, he set a new standard within cycling that has since spread across the peloton. Written from the unique perspective of both a racer and a team manager, One-Way Ticket gives the complete story of what it takes to build a winning team and repair the reputation of a sport.
