Book Synopsis In Pursuit of the Traveling Salesman by : William J. Cook
Download or read book In Pursuit of the Traveling Salesman written by William J. Cook and published by Princeton University Press. This book was released on 2014-11-09 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: The story of one of the greatest unsolved problems in mathematics What is the shortest possible route for a traveling salesman seeking to visit each city on a list exactly once and return to his city of origin? It sounds simple enough, yet the traveling salesman problem is one of the most intensely studied puzzles in applied mathematics—and it has defied solution to this day. In this book, William Cook takes readers on a mathematical excursion, picking up the salesman's trail in the 1800s when Irish mathematician W. R. Hamilton first defined the problem, and venturing to the furthest limits of today’s state-of-the-art attempts to solve it. He also explores its many important applications, from genome sequencing and designing computer processors to arranging music and hunting for planets. In Pursuit of the Traveling Salesman travels to the very threshold of our understanding about the nature of complexity, and challenges you yourself to discover the solution to this captivating mathematical problem.

Available in PDF, EPUB and Kindle. Book excerpt: What mathematical modeling uncovers about life in the city X and the City, a book of diverse and accessible math-based topics, uses basic modeling to explore a wide range of entertaining questions about urban life. How do you estimate the number of dental or doctor's offices, gas stations, restaurants, or movie theaters in a city of a given size? How can mathematics be used to maximize traffic flow through tunnels? Can you predict whether a traffic light will stay green long enough for you to cross the intersection? And what is the likelihood that your city will be hit by an asteroid? Every math problem and equation in this book tells a story and examples are explained throughout in an informal and witty style. The level of mathematics ranges from precalculus through calculus to some differential equations, and any reader with knowledge of elementary calculus will be able to follow the materials with ease. There are also some more challenging problems sprinkled in for the more advanced reader. Filled with interesting and unusual observations about how cities work, X and the City shows how mathematics undergirds and plays an important part in the metropolitan landscape.
Book Synopsis The Traveling Salesman Problem by : David L. Applegate
Download or read book The Traveling Salesman Problem written by David L. Applegate and published by Princeton University Press. This book was released on 2011-09-19 with total page 606 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the latest findings on one of the most intensely investigated subjects in computational mathematics--the traveling salesman problem. It sounds simple enough: given a set of cities and the cost of travel between each pair of them, the problem challenges you to find the cheapest route by which to visit all the cities and return home to where you began. Though seemingly modest, this exercise has inspired studies by mathematicians, chemists, and physicists. Teachers use it in the classroom. It has practical applications in genetics, telecommunications, and neuroscience. The authors of this book are the same pioneers who for nearly two decades have led the investigation into the traveling salesman problem. They have derived solutions to almost eighty-six thousand cities, yet a general solution to the problem has yet to be discovered. Here they describe the method and computer code they used to solve a broad range of large-scale problems, and along the way they demonstrate the interplay of applied mathematics with increasingly powerful computing platforms. They also give the fascinating history of the problem--how it developed, and why it continues to intrigue us.
Book Synopsis Death of a Salesman by : Arthur Miller
Download or read book Death of a Salesman written by Arthur Miller and published by Penguin. This book was released on 1998-05-01 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Pulitzer Prize-winning tragedy of a salesman’s deferred American dream Ever since it was first performed in 1949, Death of a Salesman has been recognized as a milestone of the American theater. In the person of Willy Loman, the aging, failing salesman who makes his living riding on a smile and a shoeshine, Arthur Miller redefined the tragic hero as a man whose dreams are at once insupportably vast and dangerously insubstantial. He has given us a figure whose name has become a symbol for a kind of majestic grandiosity—and a play that compresses epic extremes of humor and anguish, promise and loss, between the four walls of an American living room. "By common consent, this is one of the finest dramas in the whole range of the American theater." —Brooks Atkinson, The New York Times "So simple, central, and terrible that the run of playwrights would neither care nor dare to attempt it." —Time
Book Synopsis 50 Visions of Mathematics by : Dara O' Briain
Download or read book 50 Visions of Mathematics written by Dara O' Briain and published by OUP Oxford. This book was released on 2014-05-01 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: Relax: no one understands technical mathematics without lengthy training but we all have an intuitive grasp of the ideas behind the symbols. To celebrate the 50th anniversary of the founding of the Institute of Mathematics and its Applications (IMA), this book is designed to showcase the beauty of mathematics - including images inspired by mathematical problems - together with its unreasonable effectiveness and applicability, without frying your brain. The book is a collection of 50 original essays contributed by a wide variety of authors. It contains articles by some of the best expositors of the subject (du Sautoy, Singh and Stewart for example) together with entertaining biographical pieces and articles of relevance to our everyday lives (such as Spiegelhalter on risk and Elwes on medical imaging). The topics covered are deliberately diverse and involve concepts from simple numerology to the very cutting edge of mathematics research. Each article is designed to be read in one sitting and to be accessible to a general audience. There is also other content. There are 50 pictorial 'visions of mathematics' which were supplied in response to an open call for contributions from IMA members, Plus readers and the worldwide mathematics community. You'll also find a series of "proofs " of Phythagoras's Theorem - mathematical, literary and comedy - after this, you'll never think of Pythagoras the same way again.
Download or read book Power-Up written by Matthew Lane and published by Princeton University Press. This book was released on 2019-11-19 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Did you know that every time you pick up the controller to your PlayStation or Xbox, you are entering a game world steeped in mathematics? Power-Up reveals the hidden mathematics in many of today's most popular video games and explains why mathematical learning doesn't just happen in the classroom or from books--you're doing it without even realizing it when you play games on your cell phone. In this lively and entertaining book, Matthew Lane discusses how gamers are engaging with the traveling salesman problem when they play Assassin's Creed, why it is mathematically impossible for Mario to jump through the Mushroom Kingdom in Super Mario Bros., and how The Sims teaches us the mathematical costs of maintaining relationships. He looks at mathematical pursuit problems in classic games like Missile Command and Ms. Pac-Man, and how each time you play Tetris, you're grappling with one of the most famous unsolved problems in all of mathematics and computer science. Along the way, Lane discusses why Family Feud and Pictionary make for ho-hum video games, how realism in video games (or the lack of it) influences learning, what video games can teach us about the mathematics of voting, the mathematics of designing video games, and much more. Power-Up shows how the world of video games is an unexpectedly rich medium for learning about the beautiful mathematical ideas that touch all aspects of our lives--including our virtual ones."--Dust jacket.

Book Synopsis The Great Mathematical Problems by : Ian Stewart
Download or read book The Great Mathematical Problems written by Ian Stewart and published by Profile Books. This book was released on 2013-03-07 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are some mathematical problems whose significance goes beyond the ordinary - like Fermat's Last Theorem or Goldbach's Conjecture - they are the enigmas which define mathematics. The Great Mathematical Problems explains why these problems exist, why they matter, what drives mathematicians to incredible lengths to solve them and where they stand in the context of mathematics and science as a whole. It contains solved problems - like the Poincar Conjecture, cracked by the eccentric genius Grigori Perelman, who refused academic honours and a million-dollar prize for his work, and ones which, like the Riemann Hypothesis, remain baffling after centuries. Stewart is the guide to this mysterious and exciting world, showing how modern mathematicians constantly rise to the challenges set by their predecessors, as the great mathematical problems of the past succumb to the new techniques and ideas of the present.

Available in PDF, EPUB and Kindle. Book excerpt: The books that we read, whether travel-focused or not, may influence the way in which we understand the process or experience of travel. This multidisciplinary work provides a critical analysis of the inspirational and transformational role that books play in travel imaginings. Does reading a book encourage us to think of travel as exotic, adventurous, transformative, dangerous or educative? Do different genres of books influence a reader's view of travel in multifarious ways? These questions are explored through a literary analysis of an eclectic selection of books spanning the period from the eighteenth century to the present day. Genres covered include historical fiction, children's books, westerns, science-fiction and crime fiction.

Book Synopsis In Pursuit of Jefferson by : Derek Baxter
Download or read book In Pursuit of Jefferson written by Derek Baxter and published by Sourcebooks, Inc.. This book was released on 2022-03-15 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: A debut that combines historical nonfiction with travel books, for fans of Bill Bryson and Tony Horwitz, In Pursuit of Jefferson is the story of an American on a journey through Europe, following the epic trail of Thomas Jefferson. A controversial founding father. A man ready for a change. And a completely unique trip through Europe. In 1784, Thomas Jefferson was a broken man. Reeling from the loss of his wife and stung from a political scandal during the Revolutionary war, he needed to remake himself. To do that, he traveled. Wandering through Europe, Jefferson saw and learned as much as he could, ultimately bringing his knowledge home to a young America. There, he would rise to power and shape a nation. More than two hundred years later, Derek Baxter, a devotee of American history, stumbles on an obscure travel guide written by Jefferson—Hints for Americans Traveling Through Europe—as he's going through his own personal crisis. Who better to offer advice than a founding father himself? Using Hints as his roadmap, Baxter follows Jefferson through six countries and countless lessons. But what Baxter learns isn't always what Jefferson had in mind, and as he comes to understand Jefferson better, he doesn't always like what he finds. In Pursuit of Jefferson is at once the story of a life-changing trip through Europe, an unflinching look at a founding father, and a moving personal journey. With rich historical detail, a sense of humor, and boundless heart, Baxter explores how we can be better moving forward only by first looking back.
Book Synopsis The Golden Ticket by : Lance Fortnow
Download or read book The Golden Ticket written by Lance Fortnow and published by Princeton University Press. This book was released on 2017-02-28 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: The P-NP problem is the most important open problem in computer science, if not all of mathematics. Simply stated, it asks whether every problem whose solution can be quickly checked by computer can also be quickly solved by computer. The Golden Ticket provides a nontechnical introduction to P-NP, its rich history, and its algorithmic implications for everything we do with computers and beyond. Lance Fortnow traces the history and development of P-NP, giving examples from a variety of disciplines, including economics, physics, and biology. He explores problems that capture the full difficulty of the P-NP dilemma, from discovering the shortest route through all the rides at Disney World to finding large groups of friends on Facebook. The Golden Ticket explores what we truly can and cannot achieve computationally, describing the benefits and unexpected challenges of this compelling problem.

Book Synopsis In Pursuit of Silence by : George Prochnik
Download or read book In Pursuit of Silence written by George Prochnik and published by Anchor. This book was released on 2010-04-06 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: An "elegant and eloquent" (New York Times) exploration of the frontiers of noise and silence, and the growing war between them. Between iPods, music-blasting restaurants, earsplitting sports stadiums, and endless air and road traffic, the place for quiet in our lives grows smaller by the day. In Pursuit of Silence gives context to our increasingly desperate sense that noise pollution is, in a very real way, an environmental catastrophe. Traveling across the country and meeting and listening to a host of incredible characters, including doctors, neuroscientists, acoustical engineers, monks, activists, educators, marketers, and aggrieved citizens, George Prochnik examines why we began to be so loud as a society, and what it is that gets lost when we can no longer find quiet.
Book Synopsis In Milton Lumky Territory by : Philip K. Dick
Download or read book In Milton Lumky Territory written by Philip K. Dick and published by Macmillan. This book was released on 2009-04-27 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: In The Novels of Philip K. Dick, Kim Stanley Robinson says that "In Milton Lumky Territory . . . is probably the best of Dick's realist novels aside from Confessions of a Crap Artist," and calls it a "bitter indictment of the effects of capitalism." Dick, on the other hand, in his forward, says "This is actually a very funny book, and a good one, too." Milton Lumky territory is both an area of the western USA and a psychic terrain: the world and world-view of the traveling salesman. The story takes place in Boise, Idaho, with some extraordinary long-distance driving sequences in which our hero (young Bruce Stevens) drives from Boise to San Francisco, to Reno, to Pocatello, to Seattle, and back to Boise in search of a good deal on some wholesale typewriters. He falls under the spell of an attractive older woman, and of Milton Lumky, a middle-aged paper salesman whose territory is the Northwest. And then Bruce and the others slowly sink into the whirlpool of Bruce's immature personal obsessions and misperceptions. A compassionate and ironic portrayal of three characters enmeshed in a sticky web of everyday events, who have a basic failure to communicate, In Milton Lumky Territory stands out among Dick's early works.
