    How does professional baseball evaluate hitters? Is a singles hitter like Wade Boggs more valuable than a power hitter like David Ortiz? Should NFL teams pass or run more often on first downs? Could professional basketball have used statistics to expose the crooked referee Tim Donaghy? Does money buy performance in professional sports?In Mathletics, Wayne Winston describes the mathematical methods that top coaches and managers use to evaluate players and improve team performance, and gives math enthusiasts the practical tools they need to enhance their understanding and enjoyment of their favorite sports--and maybe even gain the outside edge to winning bets. Mathletics blends fun math problems with sports stories of actual games, teams, and players, along with personal anecdotes from Winston's work as a sports consultant. Winston uses easy-to-read tables and illustrations to illuminate the techniques and ideas he presents, and all the necessary math concepts--such as arithmetic, basic statistics and probability, and Monte Carlo simulations--are fully explained in the examples.After reading Mathletics, you will understand why baseball teams should almost never bunt, why football overtime systems are unfair, why points, rebounds, and assists aren't enough to determine who's the NBA's best player--and much, much more.

    Griffin), Dick Couch's explosive novel poses the chilling and timely question: How safe are America's waterways from terrorist threat?Riding quietly at her moorings on Puget Sound, the U.S. Navy's deadly weapon -- the Trident submarine -- waits for her return to the sea. But an Arab terrorist known as the Shadow has targeted the USS "Michigan," with nearly three hundred nuclear warheads nestled in its missile silos. He intends to take the deadliest weapon of the Cold War and turn it into the deadliest dirty bomb conceivable -- by hijacking the "Spokane," flagship of the nation's largest ferry fleet. The nation, caught by surprise, sends a select team of Navy SEALs to stop the Shadow. They are aided by a savvy FBI agent and the ferry's captain, Ross Peck. Unless the U.S. wields its political might to support his terrorist brothers in the Middle East, the Shadow will unleash a radiological holocaust, and a nightmare beyond imagining. . . .

    Keeping an open mind, looking for unusual number combinations, using multiple skills (like subtracting to add) and looking for patterns will guarantee any child success in math. In MATH APPEAL, Tang continues to challenge kids with his innovative approach to math.

    Many people regard mathematicians as a race apart, possessed of almost supernatural powers. While this is very flattering for successful mathematicians, it is very bad for those who, for one reason or another, are attempting to learn the subject.'W.W. Sawyer's deep understanding of how we learn and his lively, practical approach have made this an ideal introduction to mathematics for generations of readers. By starting at the level of simple arithmetic and algebra and then proceeding step by step through graphs, logarithms and trigonometry to calculus and the dizzying world of imaginary numbers, the book takes the mystery out of maths. Throughout, Sawyer reveals how theory is subordinate to the real-life applications of mathematics - the Pyramids were built on Euclidean principles three thousand years before Euclid formulated them - and celebrates the sheer intellectual stimulus of mathematics at its best.
