    Now, with the benefit of twenty years' worth of additional knowledge and insight, Stanton Samenow offers a completely updated edition of his classic work, including fresh perceptions into crimes in the spotlight today, from stalking and domestic violence to white-collar crime and political terrorism. Dr. Samenow's three decades of working with criminals have reaffirmed his argument that factors such as poverty, divorce, and media violence do not cause criminality. Rather, as Samenow documents here, all criminals share a particular mind-set--often evident in childhood--that is disturbingly different from that of a responsible citizen. While new types of crime have grown more prevalent, or at least more visible to the public eye--from spousal abuse to school shootings--little has changed in terms of our approach to dealing with crime. Rehabilitation programs based on the assumption that society is more to blame for crime than the criminal, an assumption for which a causal link has yet to be established, have proved to be grossly inadequate. Crime continues to invade every aspect of our lives, criminal court dockets and prisons are oppressively overcrowded and expensive, and recidivism rates continue to escalate.To embark on a truly corrective program, we must begin with the clear understanding that the criminal chooses crime; he chooses to reject society long before society rejects him. The criminal values people only to the extent that he can use them for his own self-serving ends; he does not justify his actions to himself. Only by "habilitating" the criminal, so that he sees himself realistically and develops responsible patterns of thought, can we change his behavior. It is vital that we know who the criminal is and how and why he acts differently from responsible citizens. From that understanding can come reasonable, compassionate, and effective solutions.

    Gödel received public recognition of his work in 1951 when he was awarded the first Albert Einstein Award for achievement in the natural sciences--perhaps the highest award of its kind in the United States. The award committee described his work in mathematical logic as "one of the greatest contributions to the sciences in recent times."However, few mathematicians of the time were equipped to understand the young scholar's complex proof. Ernest Nagel and James Newman provide a readable and accessible explanation to both scholars and non-specialists of the main ideas and broad implications of Gödel's discovery. It offers every educated person with a taste for logic and philosophy the chance to understand a previously difficult and inaccessible subject.New York University Press is proud to publish this special edition of one of its bestselling books. With a new introduction by Douglas R. Hofstadter, this book will appeal students, scholars, and professionals in the fields of mathematics, computer science, logic and philosophy, and science.

    In Tammet's world, numbers are beautiful and mathematics illuminates our lives and minds. Using anecdotes, everyday examples, and ruminations on history, literature, and more, Tammet allows us to share his unique insights and delight in the way numbers, fractions, and equations underpin all our lives. Inspired by the complexity of snowflakes, Anne Boleyn's eleven fingers, or his many siblings, Tammet explores questions such as why time seems to speed up as we age, whether there is such a thing as an average person, and how we can make sense of those we love. Thinking In Numbers will change the way you think about math and fire your imagination to see the world with fresh eyes.

    Traditional mathematics teaching is largely about solving exactly stated problems exactly, yet life often hands us partly defined problems needing only moderately accurate solutions. This engaging book is an antidote to the rigor mortis brought on by too much mathematical rigor, teaching us how to guess answers without needing a proof or an exact calculation.In Street-Fighting Mathematics, Sanjoy Mahajan builds, sharpens, and demonstrates tools for educated guessing and down-and-dirty, opportunistic problem solving across diverse fields of knowledge--from mathematics to management. Mahajan describes six tools: dimensional analysis, easy cases, lumping, picture proofs, successive approximation, and reasoning by analogy. Illustrating each tool with numerous examples, he carefully separates the tool--the general principle--from the particular application so that the reader can most easily grasp the tool itself to use on problems of particular interest. Street-Fighting Mathematics grew out of a short course taught by the author at MIT for students ranging from first-year undergraduates to graduate students ready for careers in physics, mathematics, management, electrical engineering, computer science, and biology. They benefited from an approach that avoided rigor and taught them how to use mathematics to solve real problems.Street-Fighting Mathematics will appear in print and online under a Creative Commons Noncommercial Share Alike license.

    An award-winning investigative journalist, he used his real name; In American Prison, Bauer weaves a much deeper reckoning with his experiences together with a thoroughly researched history of for-profit prisons in America from their origins in the decades before the Civil War. For, as he soon realized, we can't understand the cruelty of our current system and its place in the larger story of mass incarceration without understanding where it came from. Private prisons became entrenched in the South as part of a systemic effort to keep the African-American labor force in place in the aftermath of slavery, and the echoes of these shameful origins are with us still.

    Lewis explores the 100 most terrifying cover-ups of all time, from the invention of Jesus' divinity to Bush and Blair's real agenda in invading Iraq. The book provides each cover-up with a plausibility rating.

    Over the next three months, 800,000 Tutsis were murdered in the most unambiguous case of genocide since Hitler's war against the Jews. Philip Gourevitch's haunting work is an anatomy of the killings in Rwanda, a vivid history of the genocide's background, and an unforgettable account of what it means to survive in its aftermath.

    Albert-László Barabási, the nation’s foremost expert in the new science of networks and author of Bursts, takes us on an intellectual adventure to prove that social networks, corporations, and living organisms are more similar than previously thought. Grasping a full understanding of network science will someday allow us to design blue-chip businesses, stop the outbreak of deadly diseases, and influence the exchange of ideas and information. Just as James Gleick and the Erdos–Rényi model brought the discovery of chaos theory to the general public, Linked tells the story of the true science of the future and of experiments in statistical mechanics on the internet, all vital parts of what would eventually be called the Barabási–Albert model.

    Yet The Origin of Species (1859) is also a humane and inspirational vision of ecological interrelatedness, revealing the complex mutual interdependencies between animal and plant life, climate and physical environment, and—by implication—within the human world. Written for the general reader, in a style which combines the rigour of science with the subtlety of literature, The Origin of Species remains one of the founding documents of the modern age.

    But this is not the whole story.Shedding light on controversial research and investigating the ferocious gender wars in biology, psychology and anthropology, Angela Saini takes readers on an eye-opening journey to uncover how women are being rediscovered. She explores what these revelations mean for us as individuals and as a society, revealing an alternative view of science in which women are included, rather than excluded.

    The Land of Open Graves reveals the suffering and deaths that occur daily in the Sonoran Desert of Arizona as thousands of undocumented migrants attempt to cross the border from Mexico into the United States.Drawing on the four major fields of anthropology, De León uses an innovative combination of ethnography, archaeology, linguistics, and forensic science to produce a scathing critique of “Prevention through Deterrence,” the federal border enforcement policy that encourages migrants to cross in areas characterized by extreme environmental conditions and high risk of death. For two decades, this policy has failed to deter border crossers while successfully turning the rugged terrain of southern Arizona into a killing field.In harrowing detail, De León chronicles the journeys of people who have made dozens of attempts to cross the border and uncovers the stories of the objects and bodies left behind in the desert.The Land of Open Graves will spark debate and controversy.
