Each sketch contains Questions and Projects to help you learn more about its topic and to see how its main ideas fit into the bigger picture of history. The 25 short stories are preceded by a 56-page bird's-eye overview of the entire panorama of mathematical history, a whirlwind tour of the most important people, events, and trends that shaped the mathematics we know today. Reading suggestions after each sketch provide starting points for readers who want to pursue a topic further."

    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.

    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.

    It is the basis for a new approach to artificial intelligence that aims to program computers to use example data or past experience to solve a given problem. In this volume in the MIT Press Essential Knowledge series, Ethem Alpayd�n offers a concise and accessible overview of the new AI. This expanded edition offers new material on such challenges facing machine learning as privacy, security, accountability, and bias. Alpayd�n, author of a popular textbook on machine learning, explains that as Big Data has gotten bigger, the theory of machine learning--the foundation of efforts to process that data into knowledge--has also advanced. He describes the evolution of the field, explains important learning algorithms, and presents example applications. He discusses the use of machine learning algorithms for pattern recognition; artificial neural networks inspired by the human brain; algorithms that learn associations between instances; and reinforcement learning, when an autonomous agent learns to take actions to maximize reward. In a new chapter, he considers transparency, explainability, and fairness, and the ethical and legal implications of making decisions based on data.

     Ever since my parents died in the demon war, I’ve paid my way through life by using magic to con people. It’s not right, but a girl’s gotta do what she can to survive. Unfortunately, my latest con has left me smack dab in the middle of a murder scene. Now, a coven of angry mages thinks I’m the killer. In order to clear my name, I have to team up with an infuriatingly sexy warlock whose powers are far darker than he admits. Throw in a string of related murders and a vexed vampire clan, and I’m up to my eyeballs in danger. But that's not even the worst of it. When I get too close to the real killer, he casts a life-threatening curse on my grandmother. Before, I just wanted to save my own butt, but now I’ll do whatever it takes to track him down—even if it means following him through monstrous dimensions. Because I don’t play nice with magic. And when you mess with Grandma, you become #1 on my sh*t list.

    

    

    Yet geometry is so much more than shapes and numbers; indeed, it governs much of our lives—from architecture and microchips to car design, animated movies, the molecules of food, even our own body chemistry. And as Siobhan Roberts elegantly conveys in The King of Infinite Space, there can be no better guide to the majesty of geometry than Donald Coxeter, perhaps the greatest geometer of the twentieth century.Many of the greatest names in intellectual history—Pythagoras, Plato, Archimedes, Euclid— were geometers, and their creativity and achievements illuminate those of Coxeter, revealing geometry to be a living, ever-evolving endeavor, an intellectual adventure that has always been a building block of civilization. Coxeter's special contributions—his famed Coxeter groups and Coxeter diagrams—have been called by other mathematicians "tools as essential as numbers themselves," but his greatest achievement was to almost single-handedly preserve the tradition of classical geometry when it was under attack in a mathematical era that valued all things austere and rational.Coxeter also inspired many outside the field of mathematics. Artist M. C. Escher credited Coxeter with triggering his legendary Circle Limit patterns, while futurist/inventor Buckminster Fuller acknowledged that his famed geodesic dome owed much to Coxeter's vision. The King of Infinite Space is an elegant portal into the fascinating, arcane world of geometry.

    

    

    They operated out of Chu Lai the sprawling base camp on the coast of South Vietnam, home to the 23rd Infantry Division and the 75th Rangers. Their missions were conducted in the northern provinces, dubbed by the military as 1st Combat Tactical Zone (1CTZ).From Rosemary's Point at Chu Lai, to Da Nang, to the Tuy Lon River and the White Mountains, across the Hai Van Pass to Phu Bai. They were both recon and striker unit, sometimes just looking for intell, sometimes attacking and sometimes being attacked. Often deployed to reinforce a small camp or firebase. Sometimes workng as convoy security.Mostly it was HOT! Life for them was either base camp boring, or "boonie rat" intense in full "battle rattle". Sometimes assigned missions to locate or capture specific targets. All of their missions were both classified and clandestine. Even their existence was denied. As much as possible their movements were hidden or camouflaged within larger unit operations and movements. Their operations were usually conducted with niether back-up, nor support readily available. They were required to move and survive on their bush skills, to adapt, over come, improvise, or if that failed E&E (escape and evade) back to a pick-up or rendezvous point for extraction. This story is about serving in Vietnam as professional soldiers in a "No Such Unit Exists" status. Part of the "other" Army in - South Vietnam, Republic of "A HARD PLACE."

    Only 17 when he enlisted in 1964, Johnson deployed to Vietnam with the 3rd Reconnaissance Battalion, 3rd Marine Division, and his tour included such now famous locations as Phu Bai, Khe Sanh, Nha Trang and Quang Tri, among others. With a sometimes humorous tone, Johnson describes a war of often terrified high school and college-aged youngsters faced with exotic plant and animal life, monsoon rains, harrowing reconnaissance missions and death. Details are plentiful about tactics, equipment, geography and, always, fellow Marines.

    There are tranquil tropical harbours and violent storms far from shore. We are in the wireless room when ships are calling for help. The story begins with humble origins on the coast of County Durham surrounded by family still coming to terms with the Great War. The author's father went to war on horseback, yet in this story we are on the brink of the modern world. The writer was fortunate to join the Merchant Navy in the 1950s, and know its most glorious days. Harry Nicholson now lives near Whitby, on the Yorkshire coast. His other books are Tom Fleck, a Tudor novel of Cleveland and Flodden, and its sequel The Black Caravel. His collected poetry is suitably titled, Wandering About.

    

    military conducted on President’s Kennedy’s body on the night of November 22, 1963. Hornberger’s new book, The Kennedy Autopsy 2, expands on his earlier work. In this new book, you will learn: The important role that Lyndon Johnson played in the U.S. military’s fraudulent autopsy on the president’s body. The significance of various meetings at the National Archives prior to the 1968 presidential race, where autopsy pathologists signed false affidavits relating to the inventory of autopsy photographs. An alternative explanation as to why Johnson suddenly decided to drop out of the 1968 presidential race. How and why Lee Harvey Oswald escaped the U.S. government’s Cold War anticommunist crusade. And much more.
