Book Description
He who untied the Gordian knot would rule all of Asia So goes the legend of the tricky knot of Gordius, king of Phrygia.Many had tried; many had failed, but Alexander the Great simplycut the knot with his sword. He went on to conquer most of Asia, eventually reaching as far east as Northern India. Cut the Knot is a book of probability riddles curated to challenge the mind andexpand mathematical and logical thinking skills. First housed on cut-the-knot.org, these puzzles and their solutions represent the efforts of great minds around theworld. Follow along as Alexander Bogomolny presents these selected riddles bytopical progression. Try them for yourself before reading their solutions. Just like itwas for Alexander the Great, the non-trivial, unexpected solution might be exactlythe one you need.

Book Description
Knots are familiar objects. Yet the mathematical theory of knots quickly leads to deep results in topology and geometry. This work offers an introduction to this theory, starting with our understanding of knots. It presents the applications of knot theory to modern chemistry, biology and physics.

Book Description
This book introduces the study of knots, providing insights into recent applications in DNA research and graph theory. It sets forth fundamental facts such as knot diagrams, braid representations, Seifert surfaces, tangles, and Alexander polynomials. It also covers more recent developments and special topics, such as chord diagrams and covering spaces. The author avoids advanced mathematical terminology and intricate techniques in algebraic topology and group theory. Numerous diagrams and exercises help readers understand and apply the theory. Each chapter includes a supplement with interesting historical and mathematical comments.

Book Description
Veterans of the high-definition TV wars of the 1980s, the authors, social scientists as well as technologists, came to see themselves as "chroniclers and students of an intriguing and serious techno-economic conflict." Why, they asked, did so few understand the rules of the game? In a broad account accessible to generalist and specialist alike, they address the current national debate about the development of a national information infrastructure, locating the debate in a broad historical narrative that illuminates how we got here and where we may be going, and outlining a bold vision of an open communications infrastructure that will cut through the political gridlock that threatens this "information highway."Technical change the authors argue is creating a new paradigm that fits neither the free market nor regulatory control models currently in play. They detail what is wrong with the political process of the national information infrastructure policy-making and assess how different media systems (telecommunications, radio, television broadcasting,) were originally established, spelling out the technological assumptions and organizational interests on which they were based and showing why the old policy models are now breaking down. The new digital networks are not analogous to railways and highways or their electronic forebears in telephony and broadcasting; they are inherently unfriendly to centralized control of any sort, so the old traditions of common carriage and public trustee regulation and regulatory gamesmanship no longer apply. The authors' technological and historical analysis leads logically toward a policy proposal for a reformed regulatory structure that builds and protects meaningful competition, but that abandons its role as arbiter of tariffs and definer of public service and public interest.

Book Description
Research in mathematics is much more than solving puzzles, but most people will agree that solving puzzles is not just fun: it helps focus the mind and increases one's armory of techniques for doing mathematics. Mathematical Puzzles makes this connection explicit by isolating important mathematical methods, then using them to solve puzzles and prove a theorem. Features A collection of the world’s best mathematical puzzles Each chapter features a technique for solving mathematical puzzles, examples, and finally a genuine theorem of mathematics that features that technique in its proof Puzzles that are entertaining, mystifying, paradoxical, and satisfying; they are not just exercises or contest problems.

Book Description
This book is a survey of current topics in the mathematical theory of knots. For a mathematician, a knot is a closed loop in 3-dimensional space: imagine knotting an extension cord and then closing it up by inserting its plug into its outlet. Knot theory is of central importance in pure and applied mathematics, as it stands at a crossroads of topology, combinatorics, algebra, mathematical physics and biochemistry. * Survey of mathematical knot theory * Articles by leading world authorities * Clear exposition, not over-technical * Accessible to readers with undergraduate background in mathematics

Book Description
Rolfsen's beautiful book on knots and links can be read by anyone, from beginner to expert, who wants to learn about knot theory. Beginners find an inviting introduction to the elements of topology, emphasizing the tools needed for understanding knots, the fundamental group and van Kampen's theorem, for example, which are then applied to concrete problems, such as computing knot groups. For experts, Rolfsen explains advanced topics, such as the connections between knot theory and surgery and how they are useful to understanding three-manifolds. Besides providing a guide to understanding knot theory, the book offers 'practical' training. After reading it, you will be able to do many things: compute presentations of knot groups, Alexander polynomials, and other invariants; perform surgery on three-manifolds; and visualize knots and their complements.It is characterized by its hands-on approach and emphasis on a visual, geometric understanding. Rolfsen offers invaluable insight and strikes a perfect balance between giving technical details and offering informal explanations. The illustrations are superb, and a wealth of examples are included. Now back in print by the AMS, the book is still a standard reference in knot theory. It is written in a remarkable style that makes it useful for both beginners and researchers. Particularly noteworthy is the table of knots and links at the end. This volume is an excellent introduction to the topic and is suitable as a textbook for a course in knot theory or 3-manifolds. Other key books of interest on this topic available from the AMS are ""The Shoelace Book: A Mathematical Guide to the Best (and Worst) Ways to Lace your Shoes"" and ""The Knot Book.""

Book Description
For over a century, American have created laws, processes, objectives, priorities, and rules for federal land management that often conflict with each other. We now have inconsistent laws, unclear priorities, procedural mazes, and an antiquated bureaucratic structure. The result is a loss of public benefits and undesirable impact on natural resources. The author argues for major changes and offers new ideas for how those changes can be accomplished.

From the #1 New York Times bestselling author of The Party Crasher and Love Your Life . . . “Sophie Kinsella keeps her finger on the cultural pulse, while leaving me giddy with laughter.”—Jojo Moyes, author of The Giver of Stars and The Last Letter from Your Lover Life has been good to Becky Bloomwood: She’s become the top personal shopper at Barneys and she’s living happily with her boyfriend, Luke, in Manhattan’s West Village. But with her best friend, Suze, engaged, how can Becky fail to notice that her own ring finger is bare? Not that she’s been thinking about marriage (or diamonds) or anything. Then Luke proposes! Problem is, two other people are planning her wedding: Becky’s overjoyed mother—who has been waiting forever to host a backyard wedding, with the bride resplendent in Mum’s frilly old gown; and her high-society soon-to-be mother-in-law—who insists on a glamorous, all-expenses-paid affair at the Plaza. Both weddings, on separate continents, on the same day . . . and Becky can’t seem to turn down either one. Can everyone’s favorite shopaholic tie the knot before everything unravels? Praise for Sophie Kinsella and Shopaholic Ties the Knot “Kinsella has a genuine gift for comic writing.”—The Boston Globe “Witty and hilarious.”—Cosmopolitan (U.K.) “Another entertaining entry in Kinsella’s unabashedly fluffy Shopaholic series . . . chock-full of the charming antics and asides that made the first two installments hilarious best-sellers.”—Booklist “Kinsella’s Bloomwood is plucky and funny. . . . You won’t have to shop around to find a more winning protagonist.”—People
