Understanding Topology: A Practical Introduction
by Shaun V. AultA fresh approach to topology makes this complex topic easier for students to master.Topology—the branch of mathematics that studies the properties of spaces that remain unaffected by stretching and other distortions—can present significant challenges for undergraduate students of mathematics and the sciences. Understanding Topology aims to change that.The perfect introductory topology textbook, Understanding Topology requires only a knowledge of calculus and a general familiarity with set theory and logic. Equally approachable and rigorous, the book's clear organization, worked examples, and concise writing style support a thorough understanding of basic topological principles. Professor Shaun V. Ault's unique emphasis on fascinating applications, from mapping DNA to determining the shape of the universe, will engage students in a way traditional topology textbooks do not.This groundbreaking new text:• presents Euclidean, abstract, and basic algebraic topology• explains metric topology, vector spaces and dynamics, point-set topology, surfaces, knot theory, graphs and map coloring, the fundamental group, and homology• includes worked example problems, solutions, and optional advanced sections for independent projectsFollowing a path that will work with any standard syllabus, the book is arranged to help students reach that "Aha!" moment, encouraging readers to use their intuition through local-to-global analysis and emphasizing topological invariants to lay the groundwork for algebraic topology.

The Unexpected Legacy of Divorce: A 25 Year Landmark Study
by Sandra Blakeslee Julia M. LewisDivorce is at once a widespread reality and a painful decision, so it is no surprise that this landmark study of its long-term effects should both spark debate and find a large audience.In this compelling, thought-provoking book, Judith Wallerstein explains that, while children do learn to cope with divorce, it in fact takes its greatest toll in adulthood, when the sons and daughters of divorced parents embark on romantic relationships of their own. Wallerstein sensitively illustrates how children of divorce often feel that their relationships are doomed, seek to avoid conflict, and fear commitment. Failure in their loving relationships often seems to them preordained, even when things are going smoothly. As Wallerstein checks in on the adults she first encountered as youngsters more than twenty-five years ago, she finds that their experiences mesh with those of the millions of other children of divorce, who will find themselves on every page.With more than 100,000 copies in print, The Unexpected Legacy of Divorce spent three weeks on the New York Times, San Francisco Chronicle, and Denver Post bestseller lists. The book was also featured on two episodes of Oprah as well as on the front cover of Time and the New York Times Book Review.

Unleashing the Ideavirus: Stop Marketing AT People! Turn Your Ideas into Epidemics by Helping Your Customers Do the Marketing Thing for You.
by Malcolm Gladwell Seth GodinThe book that sparked a marketing revolution."This is a subversive book. It says that the marketer is not--and ought not to be--at the center of successful marketing. The customer should be. Are you ready for that?" --From the Foreword by Malcolm Gladwell, author of The Tipping Point.Counter to traditional marketing wisdom, which tries to count, measure, and manipulate the spread of information, Seth Godin argues that the information can spread most effectively from customer to customer, rather than from business to customer. Godin calls this powerful customer-to- customer dialogue the ideavirus, and cheerfully eggs marketers on to create an environment where their ideas can replicate and spread.In lively detail, Godin looks at the ways companies such as PayPal, Hotmail, GeoCities, even Volkswagen have successfully launched ideaviruses. He offers a "recipe" for creating your own ideavirus, identifies the key factors in the successful spread of an ideavirus (powerful sneezers, hives, a clear vector, a smooth, friction-free transmission), and shows how any business, large or small, can use ideavirus marketing to succeed in a world that just doesn't want to hear it anymore from the traditional marketers.
