More and more leading businesses today use estimation questions in interviews to test applicants' abilities to think on their feet. Guesstimation enables anyone with basic math and science skills to estimate virtually anything--quickly--using plausible assumptions and elementary arithmetic.Lawrence Weinstein and John Adam present an eclectic array of estimation problems that range from devilishly simple to quite sophisticated and from serious real-world concerns to downright silly ones. How long would it take a running faucet to fill the inverted dome of the Capitol? What is the total length of all the pickles consumed in the US in one year? What are the relative merits of internal-combustion and electric cars, of coal and nuclear energy? The problems are marvelously diverse, yet the skills to solve them are the same. The authors show how easy it is to derive useful ballpark estimates by breaking complex problems into simpler, more manageable ones--and how there can be many paths to the right answer. The book is written in a question-and-answer format with lots of hints along the way. It includes a handy appendix summarizing the few formulas and basic science concepts needed, and its small size and French-fold design make it conveniently portable. Illustrated with humorous pen-and-ink sketches, Guesstimation will delight popular-math enthusiasts and is ideal for the classroom.

    Atbashian explains why Socialism cannot work. He exposes the injustice of "Collective Greed" and shows why Economic Equality is a fraud. The book is an eye-opener as the author illustrates his points with examples drawn from his life in the Soviet Union before 1994 and more recent events in the USA. "Oleg Atbashian has written a timely warning for Americans about the collectivists among us and their plans for the future. I hope everyone reads this book." -- David Horowitz, Author of One Party Classroom (2009) "In his brilliant, witty, and wonderfully illustrated Shakedown Socialism, Oleg Atbashian -- who grew up in the Soviet Union, shows what is happening in Obama's America today, and explains why it is putting us on the road to ruin. Shakedown Socialism is an enlightening, sobering, and wonderfully clear explanation of why statism kills -- and thus also of why and how Barack Obama is killing the American economy. This book shows why Obama's statist economic policies are a looming disaster for America and for the spirit of the free human individual." -- Pamela Geller, author, The Post-American Presidency: The Obama Administration's War On America "Brightly written and filled with entertaining and illuminating illustrations, Oleg Atbashian's Shakedown Socialism is a clear and eye-opening guide to exactly what is wrong with socialism and state control of the means of production, and how it kills both the economy and human initiative. Shakedown Socialism is an essential and inspiring guide to the virtues of the free market." -- Robert Spencer, author of the New York Times bestsellers The Politically Incorrect Guide to Islam (and the Crusades) and The Truth About Muhammad

    These include tipping points, the sociological term used to describe moments when unique or rare phenomena become more commonplace; the wisdom of crowds, the argument that certain types of groups harness information and make decisions in more effective ways than individuals; six degrees of separation, the idea that it takes no more than six steps to find some form of connection between two random individuals; and emergence, the idea that new properties, processes, and structures can emerge unexpectedly from complex systems.

    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.

    Each technique is introduced with a simple, jargon-free explanation, practical examples, and hands-on guidance for solving real problems with Excel or a TI-83/84 series calculator, including Plus models. Hate math? No sweat. You'll be amazed how little you need! For those who do have an interest in mathematics, optional "Equation Blackboard" sections review the equations that provide the foundations for important concepts. David M. Levine is a much-honored innovator in statistics education. He is Professor Emeritus of Statistics and Computer Information Systems at Bernard M.
