Linear Programming and Extensions

by George Dantzig

In real-world problems related to finance, business, and management, mathematicians and economists frequently encounter optimization problems. In this classic book, George Dantzig looks at a wealth of examples and develops linear programming methods for their solutions. He begins by introducing the basic theory of linear inequalities and describes the powerful simplex method used to solve them. Treatments of the price concept, the transportation problem, and matrix methods are also given, and key mathematical concepts such as the properties of convex sets and linear vector spaces are covered. George Dantzig is properly acclaimed as the "father of linear programming." Linear programming is a mathematical technique used to optimize a situation. It can be used to minimize traffic congestion or to maximize the scheduling of airline flights. He formulated its basic theoretical model and discovered its underlying computational algorithm, the "simplex method," in a pathbreaking memorandum published by the United States Air Force in early 1948. Linear Programming and Extensions provides an extraordinary account of the subsequent development of his subject, including research in mathematical theory, computation, economic analysis, and applications to industrial problems. Dantzig first achieved success as a statistics graduate student at the University of California, Berkeley. One day he arrived for a class after it had begun, and assumed the two problems on the board were assigned for homework. When he handed in the solutions, he apologized to his professor, Jerzy Neyman, for their being late but explained that he had found the problems harder than usual. About six weeks later, Neyman excitedly told Dantzig, "I've just written an introduction to one of your papers. Read it so I can send it out right away for publication." Dantzig had no idea what he was talking about. He later learned that the "homework" problems had in fact been two famous unsolved problems in statistics.

#Republic: Divided Democracy in the Age of Social Media

by Cass R. Sunstein

From the New York Times bestselling author of Nudge and The World According to Star Wars, a revealing account of how today's Internet threatens democracy—and what can be done about itAs the Internet grows more sophisticated, it is creating new threats to democracy. Social media companies such as Facebook can sort us ever more efficiently into groups of the like-minded, creating echo chambers that amplify our views. It's no accident that on some occasions, people of different political views cannot even understand each other. It's also no surprise that terrorist groups have been able to exploit social media to deadly effect.Welcome to the age of #Republic.In this revealing book, Cass Sunstein, the New York Times bestselling author of Nudge and The World According to Star Wars, shows how today's Internet is driving political fragmentation, polarization, and even extremism—and what can be done about it.Thoroughly rethinking the critical relationship between democracy and the Internet, Sunstein describes how the online world creates "cybercascades," exploits "confirmation bias," and assists "polarization entrepreneurs." And he explains why online fragmentation endangers the shared conversations, experiences, and understandings that are the lifeblood of democracy.In response, Sunstein proposes practical and legal changes to make the Internet friendlier to democratic deliberation. These changes would get us out of our information cocoons by increasing the frequency of unchosen, unplanned encounters and exposing us to people, places, things, and ideas that we would never have picked for our Twitter feed.#Republic need not be an ironic term. As Sunstein shows, it can be a rallying cry for the kind of democracy that citizens of diverse societies most need.

Unsolved!: The History and Mystery of the World's Greatest Ciphers from Ancient Egypt to Online Secret Societies

by Craig P. Bauer

A mathematical tour of some of the greatest unsolved ciphers of all timeIn 1953, a man was found dead from cyanide poisoning near the Philadelphia airport with a picture of a Nazi aircraft in his wallet. Taped to his abdomen was an enciphered message. In 1912, a book dealer named Wilfrid Voynich came into possession of an illuminated cipher manuscript once belonging to Emperor Rudolf II, who was obsessed with alchemy and the occult. Wartime codebreakers tried—and failed—to unlock the book's secrets, and it remains an enigma to this day. In this lively and entertaining book, Craig Bauer examines these and other vexing ciphers yet to be cracked. Some may reveal the identity of a spy or serial killer, provide the location of buried treasure, or expose a secret society—while others may be elaborate hoaxes.Unsolved! begins by explaining the basics of cryptology, and then explores the history behind an array of unsolved ciphers. It looks at ancient ciphers, ciphers created by artists and composers, ciphers left by killers and victims, Cold War ciphers, and many others. Some are infamous, like the ciphers in the Zodiac letters, while others were created purely as intellectual challenges by figures such as Nobel Prize–winning physicist Richard P. Feynman. Bauer lays out the evidence surrounding each cipher, describes the efforts of geniuses and eccentrics—in some cases both—to decipher it, and invites readers to try their hand at puzzles that have stymied so many others.Unsolved! takes readers from the ancient world to the digital age, providing an amazing tour of many of history's greatest unsolved ciphers.

The Great Formal Machinery Works: Theories of Deduction and Computation at the Origins of the Digital Age

by Jan Von Plato

The information age owes its existence to a little-known but crucial development, the theoretical study of logic and the foundations of mathematics. The Great Formal Machinery Works draws on original sources and rare archival materials to trace the history of the theories of deduction and computation that laid the logical foundations for the digital revolution.Jan von Plato examines the contributions of figures such as Aristotle; the nineteenth-century German polymath Hermann Grassmann; George Boole, whose Boolean logic would prove essential to programming languages and computing; Ernst Schröder, best known for his work on algebraic logic; and Giuseppe Peano, cofounder of mathematical logic. Von Plato shows how the idea of a formal proof in mathematics emerged gradually in the second half of the nineteenth century, hand in hand with the notion of a formal process of computation. A turning point was reached by 1930, when Kurt Gödel conceived his celebrated incompleteness theorems. They were an enormous boost to the study of formal languages and computability, which were brought to perfection by the end of the 1930s with precise theories of formal languages and formal deduction and parallel theories of algorithmic computability. Von Plato describes how the first theoretical ideas of a computer soon emerged in the work of Alan Turing in 1936 and John von Neumann some years later.Shedding new light on this crucial chapter in the history of science, The Great Formal Machinery Works is essential reading for students and researchers in logic, mathematics, and computer science.

Disruptive Fixation: School Reform and the Pitfalls of Techno-Idealism

by Christo Sims

In New York City in 2009, a new kind of public school opened its doors to its inaugural class of middle schoolers. Conceived by a team of game designers and progressive educational reformers and backed by prominent philanthropic foundations, it promised to reinvent the classroom for the digital age. Ethnographer Christo Sims documented the life of the school from its planning stages to the graduation of its first eighth-grade class. Disruptive Fixation is his account of how this "school for digital kids," heralded as a model of tech-driven educational reform, reverted to a more conventional type of schooling with rote learning, an emphasis on discipline, and traditional hierarchies of authority. Troubling gender and racialized class divisions also emerged.Sims shows how the philanthropic possibilities of new media technologies are repeatedly idealized even though actual interventions routinely fall short of the desired outcomes—often dramatically so. He traces the complex processes by which idealistic tech-reform perennially takes root, unsettles the worlds into which it intervenes, and eventually stabilizes in ways that remake and extend many of the social predicaments reformers hope to fix. Sims offers a nuanced look at the roles that powerful elites, experts, the media, and the intended beneficiaries of reform—in this case, the students and their parents—play in perpetuating the cycle.Disruptive Fixation offers a timely examination of techno-philanthropism and the yearnings and dilemmas it seeks to address, revealing what failed interventions do manage to accomplish—and for whom.

Noncooperative Game Theory: An Introduction for Engineers and Computer Scientists

by João P. Hespanha

Noncooperative Game Theory is aimed at students interested in using game theory as a design methodology for solving problems in engineering and computer science. João Hespanha shows that such design challenges can be analyzed through game theoretical perspectives that help to pinpoint each problem's essence: Who are the players? What are their goals? Will the solution to "the game" solve the original design problem? Using the fundamentals of game theory, Hespanha explores these issues and more.The use of game theory in technology design is a recent development arising from the intrinsic limitations of classical optimization-based designs. In optimization, one attempts to find values for parameters that minimize suitably defined criteria—such as monetary cost, energy consumption, or heat generated. However, in most engineering applications, there is always some uncertainty as to how the selected parameters will affect the final objective. Through a sequential and easy-to-understand discussion, Hespanha examines how to make sure that the selection leads to acceptable performance, even in the presence of uncertainty—the unforgiving variable that can wreck engineering designs. Hespanha looks at such standard topics as zero-sum, non-zero-sum, and dynamics games and includes a MATLAB guide to coding.Noncooperative Game Theory offers students a fresh way of approaching engineering and computer science applications.An introduction to game theory applications for students of engineering and computer science Materials presented sequentially and in an easy-to-understand fashionTopics explore zero-sum, non-zero-sum, and dynamics gamesMATLAB commands are included

The Mathematics of Secrets: Cryptography from Caesar Ciphers to Digital Encryption

by Joshua Holden

The Mathematics of Secrets takes readers on a fascinating tour of the mathematics behind cryptography—the science of sending secret messages. Most books about cryptography are organized historically, or around how codes and ciphers have been used, such as in government and military intelligence or bank transactions. Joshua Holden instead shows how mathematical principles underpin the ways that different codes and ciphers operate. Holden focuses on both code making and code breaking and he discusses the majority of ancient and modern ciphers currently known.Holden begins by looking at substitution ciphers, built by substituting one letter or block of letters for another. Explaining one of the simplest and historically well-known ciphers, the Caesar cipher, Holden establishes the key mathematical idea behind the cipher and discusses how to introduce flexibility and additional notation. Holden goes on to explore polyalphabetic substitution ciphers, transposition ciphers, including one developed by the Spartans, connections between ciphers and computer encryption, stream ciphers, and ciphers involving exponentiation. He also examines public-key ciphers, where the methods used to encrypt messages are public knowledge, and yet, intended recipients are still the only ones who are able to read the message. He concludes with a look at the future of ciphers and where cryptography might be headed. Only basic mathematics up to high school algebra is needed to understand and enjoy the book.With a plethora of historical anecdotes and real-world examples, The Mathematics of Secrets reveals the mathematics working stealthily in the science of coded messages.

The Contentious Public Sphere: Law, Media, and Authoritarian Rule in China

by Ya-Wen Lei

Since the mid-2000s, public opinion and debate in China have become increasingly common and consequential, despite the ongoing censorship of speech and regulation of civil society. How did this happen? In The Contentious Public Sphere, Ya-Wen Lei shows how the Chinese state drew on law, the media, and the Internet to further an authoritarian project of modernization, but in so doing, inadvertently created a nationwide public sphere in China—one the state must now endeavor to control. Lei examines the influence this unruly sphere has had on Chinese politics and the ways that the state has responded.Using interviews, newspaper articles, online texts, official documents, and national surveys, Lei shows that the development of the public sphere in China has provided an unprecedented forum for citizens to influence the public agenda, demand accountability from the government, and organize around the concepts of law and rights. She demonstrates how citizens came to understand themselves as legal subjects, how legal and media professionals began to collaborate in unexpected ways, and how existing conditions of political and economic fragmentation created unintended opportunities for political critique, particularly with the rise of the Internet. The emergence of this public sphere—and its uncertain future—is a pressing issue with important implications for the political prospects of the Chinese people.Investigating how individuals learn to use public discourse to influence politics, The Contentious Public Sphere offers new possibilities for thinking about the transformation of state-society relations.

Click: What Millions of People Are Doing Online and Why It Matters

by Bill Tancer

What time of year do teenage girls search for prom dresses online? How does the quick adoption of technology affect business success (and how is that related to corn farmers in Iowa)? How do time and money affect the gender of visitors to online dating sites? And how is the Internet itself affecting the way we experience the world? In Click, Bill Tancer takes us behind the scenes into the massive database of online intelligence to reveal the naked truth about how we use the Web, navigate to sites, and search for information--and what all of that says about who we are. As online directories replace the yellow pages, search engines replace traditional research, and news sites replace newsprint, we are in an age in which we've come to rely tremendously on the Internet--leaving behind a trail of information about ourselves as a culture and the direction in which we are headed. With surprising and practical insight, Tancer demonstrates how the Internet is changing the way we absorb information and how understanding that change can be used to our advantage in business and in life. Click analyzes the new generation of consumerism in a way no other book has before, showing how we use the Internet, and how those trends provide a wealth of market research nearly as vast as the Internet itself. Understanding how we change is integral to our success. After all, we are what we click.
