    It emphasizes forms suitable for students and researchers whose interest lies in solving equations rather than in general theory. Solutions to odd-numbered problems appear at the end. 1957 edition.

    How can we catch schools that cheat on standardized tests? How does Netflix know which movies you’ll like? What is causing the rising incidence of autism? As best-selling author Charles Wheelan shows us in Naked Statistics, the right data and a few well-chosen statistical tools can help us answer these questions and more.For those who slept through Stats 101, this book is a lifesaver. Wheelan strips away the arcane and technical details and focuses on the underlying intuition that drives statistical analysis. He clarifies key concepts such as inference, correlation, and regression analysis, reveals how biased or careless parties can manipulate or misrepresent data, and shows us how brilliant and creative researchers are exploiting the valuable data from natural experiments to tackle thorny questions.And in Wheelan’s trademark style, there’s not a dull page in sight. You’ll encounter clever Schlitz Beer marketers leveraging basic probability, an International Sausage Festival illuminating the tenets of the central limit theorem, and a head-scratching choice from the famous game show Let’s Make a Deal—and you’ll come away with insights each time. With the wit, accessibility, and sheer fun that turned Naked Economics into a bestseller, Wheelan defies the odds yet again by bringing another essential, formerly unglamorous discipline to life.

    Covering such turning points as the little-known Celtic and Welsh influences on English, the impact of the Viking raids and the Norman Conquest, and the Germanic invasions that started it all during the fifth century ad, John McWhorter narrates this colorful evolution with vigor. Drawing on revolutionary genetic and linguistic research as well as a cache of remarkable trivia about the origins of English words and syntax patterns, Our Magnificent Bastard Tongue ultimately demonstrates the arbitrary, maddening nature of English--and its ironic simplicity due to its role as a streamlined lingua franca during the early formation of Britain. This is the book that language aficionados worldwide have been waiting for (and no, it's not a sin to end a sentence with a preposition).

     'Extremely well written. Compelling, accurate, insightful and brilliant in the way it captures the New Zealand way. - John Hart, former All Blacks coach.With a better winning record than any other sports team in history, they stand head and shoulders above their nearest rugby rivals, and go to the 2019 World Cup as back-to-back World Champions. How did a country of just 4.8 million people conquer the world?Peter Bills, who has reported on international rugby for more than 40 years, was given exclusive access to all the key figures in New Zealand rugby as he set out to understand the secrets behind the All Blacks success. From Steve Hansen to Beauden Barrett, Richie McCaw to the late Sir Colin Meads, Peter Bills talked at length with over 90 people, both in New Zealand and around the world, with intimate knowledge of what makes the All Blacks tick.This is a story of the first settlers, and the 'Originals' who forged the All Blacks legacy, right through to modern times. It draws heavily on the contributions made by all New Zealanders: players, coaches, officials, supporters and those who have worn the most recognized jersey in the world. Intrinsically, The Jersey goes to the heart of the All Blacks success. It is also an epic story of not just a rugby team but a nation, whose identities are inextricably linked. Additionally, it debates a question, terrifying for any of their opponents. Could the All Blacks get even better?

    Pete Van Wieren’s legacy began in 1976, when he and a young Skip Caray were hired to call Atlanta Braves games. During the next three decades, "the Professor" and Caray became the voices of a team known nationwide as America's Team courtesy of Ted Turner's SuperStation TBS. In this heartfelt autobiography, Van Wieren shares his memories of thrilling moments in Braves history, such as the 1995 season when the Braves won the world championship; the pitching mastery of Greg Maddux, Tom Glavine, and John Smoltz; the heartbreak of the 1996 World Series loss to the Yankees; and Atlanta's unprecedented run of 14 consecutive division titles.

    With it has come vast amounts of data in a variety of fields such as medicine, biology, finance, and marketing. The challenge of understanding these data has led to the development of new tools in the field of statistics, and spawned new areas such as data mining, machine learning, and bioinformatics. Many of these tools have common underpinnings but are often expressed with different terminology. This book describes the important ideas in these areas in a common conceptual framework. While the approach is statistical, the emphasis is on concepts rather than mathematics. Many examples are given, with a liberal use of color graphics. It should be a valuable resource for statisticians and anyone interested in data mining in science or industry. The book's coverage is broad, from supervised learning (prediction) to unsupervised learning. The many topics include neural networks, support vector machines, classification trees and boosting—the first comprehensive treatment of this topic in any book. Trevor Hastie, Robert Tibshirani, and Jerome Friedman are professors of statistics at Stanford University. They are prominent researchers in this area: Hastie and Tibshirani developed generalized additive models and wrote a popular book of that title. Hastie wrote much of the statistical modeling software in S-PLUS and invented principal curves and surfaces. Tibshirani proposed the Lasso and is co-author of the very successful An Introduction to the Bootstrap. Friedman is the co-inventor of many data-mining tools including CART, MARS, and projection pursuit.

    Nobody is perfect. And that includes five of the greatest scientists in history—Charles Darwin, William Thomson (Lord Kelvin), Linus Pauling, Fred Hoyle, and Albert Einstein. But the mistakes that these great luminaries made helped advance science. Indeed, as Mario Livio explains, science thrives on error, advancing when erroneous ideas are disproven.As a young scientist, Einstein tried to conceive of a way to describe the evolution of the universe at large, based on General Relativity—his theory of space, time, and gravity. Unfortunately he fell victim to a misguided notion of aesthetic simplicity. Fred Hoyle was an eminent astrophysicist who ridiculed an emerging theory about the origin of the universe that he dismissively called “The Big Bang.” The name stuck, but Hoyle was dead wrong in his opposition.They, along with Darwin (a blunder in his theory of Natural Selection), Kelvin (a blunder in his calculation of the age of the earth), and Pauling (a blunder in his model for the structure of the DNA molecule), were brilliant men and fascinating human beings. Their blunders were a necessary part of the scientific process. Collectively they helped to dramatically further our knowledge of the evolution of life, the Earth, and the universe.

    In Turing’s Cathedral, George Dyson focuses on a small group of men and women, led by John von Neumann at the Institute for Advanced Study in Princeton, New Jersey, who built one of the first computers to realize Alan Turing’s vision of a Universal Machine. Their work would break the distinction between numbers that mean things and numbers that do things—and our universe would never be the same. Using five kilobytes of memory (the amount allocated to displaying the cursor on a computer desktop of today), they achieved unprecedented success in both weather prediction and nuclear weapons design, while tackling, in their spare time, problems ranging from the evolution of viruses to the evolution of stars. Dyson’s account, both historic and prophetic, sheds important new light on how the digital universe exploded in the aftermath of World War II. The proliferation of both codes and machines was paralleled by two historic developments: the decoding of self-replicating sequences in biology and the invention of the hydrogen bomb. It’s no coincidence that the most destructive and the most constructive of human inventions appeared at exactly the same time.  How did code take over the world? In retracing how Alan Turing’s one-dimensional model became John von Neumann’s two-dimensional implementation, Turing’s Cathedral offers a series of provocative suggestions as to where the digital universe, now fully three-dimensional, may be heading next.

    The allure of money is especially strong. Coins represent real value. The warmth of silver and the weight of gold are irresistible to some. Coins travel throughout the world and through time itself, representing and absorbing history as they pass from one person to the next. Oh the stories coins could tell if they only had voices.Coin-collecting is a relaxing and inexpensive (although it can be very expensive!) hobby. If you buy properly, coins can be an excellent place to park your money for a rainy day, and if you buy the right coins and the market improves, you may even be able to make a profit on your collection. In fact, n"umismatics" (the fancy term for coin collecting) offers more riches than you may realize. This rewarding hobby also opens the door to some serious life skills, such asHistoryGeographyObservational skillsOrganizational skillsAnalytical tools.This book is designed to appeal to collectors at every level, from beginner to advanced. This is not a hardcore coin book; rather, "Coin Collecting For Dummies" is a great general reference that points you in different directions for further investigation. Perhaps the most important goal of this book is to get you excited - and to keep you excited - about coin collecting. "Coin Collecting For Dummies" covers all these topics and more: Deciding what to collectStoring your collection correctlyFinding out about repaired, restored, and recolored coinsPricing world coinsFinding a good coin dealerBuying at auctionUnderstanding that condition equals valueExploring the wild side with rare, expensive, and esoteric coinsSelling your coinsNo one needs coins, but if you decide to collect them, you certainly need this book. Coin collecting can sometimes be a confusing maze of choices sprinkled with little traps along the way. Sure, you can go it alone, but why not make your journey into numismatics a lot easier by picking the brain of an expert collector and learning from the mistakes of others.

    In 1905 an unknown 26-year-old clerk at the Swiss Patent Office, who had supposedly failed math in school, burst on to the scientific scene and swept away the hidebound theories of the day. The clerk, Albert Einstein, introduced a new and unexpected understanding of the universe and launched the two great revolutions of twentieth-century physics, relativity and quantum mechanics. The obscure origin and wide-ranging brilliance of the work recalled Isaac Newton’s “annus mirabilis” (miracle year) of 1666, when as a 23-year-old seeking safety at his family manor from an outbreak of the plague, he invented calculus and laid the foundations for his theory of gravity. Like Newton, Einstein quickly became a scientific icon--the image of genius and, according to Time magazine, the Person of the Century.The actual story is much more interesting. Einstein himself once remarked that “science as something coming into being ... is just as subjectively, psychologically conditioned as are all other human endeavors.” In this profile, the historian of science L. Randles Lagerstrom takes you behind the myth and into the very human life of the young Einstein. From family rifts and girlfriend troubles to financial hardships and jobless anxieties, Einstein’s early years were typical of many young persons. And yet in the midst of it all, he also saw his way through to profound scientific insights. Drawing upon correspondence from Einstein, his family, and his friends, Lagerstrom brings to life the young Einstein and enables the reader to come away with a fuller and more appreciative understanding of Einstein the person and the origins of his revolutionary ideas.About the cover image: While walking to work six days a week as a patent clerk in Bern, Switzerland, Einstein would pass by the famous "Zytglogge" tower and its astronomical clocks. The daily juxtaposition was fitting, as the relative nature of time and clock synchronization would be one of his revolutionary discoveries in the miracle year of 1905.

    Taking us on a journey through every fundamental field of science, as well as the history of civilization, art, moral values, and the theory of political institutions, Deutsch tracks how we form new explanations and drop bad ones, explaining the conditions under which progress—which he argues is potentially boundless—can and cannot happen. Hugely ambitious and highly original, The Beginning of Infinity explores and establishes deep connections between the laws of nature, the human condition, knowledge, and the possibility for progress.
