Why do people go to war? Is it rooted in human nature or is it a late cultural invention? How does war relate to the other fundamental developments in the history of human civilization? And what of war today--is it a declining phenomenon or simply changing its shape? In this sweeping study of war and civilization, Azar Gat sets out to find definitive answers to these questions in an attempt to unravel the riddle of war throughout human history, from the early hunter-gatherers right through to the unconventional terrorism of the twenty-first century. In the process, the book generates an astonishing wealth of original and fascinating insights on all major aspects of humankind's remarkable journey through the ages, engaging a wide range of disciplines, from anthropology and evolutionary psychology to sociology and political science. Written with remarkable verve and clarity and wholly free from jargon, it will be of interest to anyone who has ever pondered the puzzle of war.

Did Newton "unweave the rainbow" by reducing it to its prismatic colors, as Keats contended? Did he, in other words, diminish beauty? Far from it, says acclaimed scientist Richard Dawkins; Newton's unweaving is the key to much of modern astronomy and to the breathtaking poetry of modern cosmology. Mysteries don't lose their poetry because they are solved: the solution often is more beautiful than the puzzle, uncovering deeper mysteries. With the wit, insight, and spellbinding prose that have made him a best-selling author, Dawkins takes up the most important and compelling topics in modern science, from astronomy and genetics to language and virtual reality, combining them in a landmark statement of the human appetite for wonder. This is the book Richard Dawkins was meant to write: a brilliant assessment of what science is (and isn't), a tribute to science not because it is useful but because it is uplifting.

Open source resources are completely common within our society. Yet open source and free software remain a mystery. Science, public highways, city parks, language—these are at the core of any free society. Commerce gets built upon them. Culture flourishes through them. Yet the same ideas applied to software puzzle many people. Language can be free, and the results of science open to all, yet to many, software is, or should be, proprietary.

From local trial courts to the United States Supreme Court, judges' decisions affect the fates of individual litigants and the fate of the nation as a whole. Scholars have long discussed and debated explanations of judicial behavior. This book examines the major issues in the debates over how best to understand judicial behavior and assesses what we actually know about how judges decide cases. It concludes that we are far from understanding why judges choose the positions they take in court. Lawrence Baum considers three issues in examining judicial behavior. First, the author considers the balance between the judges' interest in the outcome of particular cases and their interest in other goals such as personal popularity and lighter workloads. Second, Baum considers the relative importance of good law and good policy as bases for judges' choices. Finally Baum looks at the extent to which judges act strategically, choosing their own positions after taking into account the positions that their fellow judges and other policy makers might adopt. Baum argues that the evidence on each of these issues is inconclusive and that there remains considerable room for debate about the sources of judges' decisions. Baum concludes that this lack of resolution is not the result of weaknesses in the scholarship but from the difficulty in explaining human behavior. He makes a plea for diversity in research. This book will be of interest to political scientists and scholars in law and courts as well as attorneys who are interested in understanding judges as decision makers and who want to understand what we can learn from scholarly research about judicial behavior. Lawrence Baum is Professor of Political Science, Ohio State University.

Thanks to TV's crime scene investigation shows, forensic technology has entered popular culture. Combining puzzle solving and a dramatic storyline, these shows fascinate audiences as high-tech procedures uncover the truths hidden in seemingly insignificant clues. What many people may not realize is that forensic teams also use items they probably have in their own homes Â- digital cameras, computers, and Photoshop image editing software. "Adobe Photoshop Forensics: Sleuths, Truths, and Fauxtography" shows you how Photoshop is used to create many types of fakery and fraud, including scientific, counterfeiting, art, journalism, and political propaganda. You'll discover that with some basic training in Photoshop's manipulation capabilities and a critical eye, you too can see through photographic hoaxes. Follow along as each chapter explores a different genre of real-life frauds, both historical and current, and explains how the fakery was or could be detected. A featured case file in each chapter carefully deconstructs a faked image so you can see the methods and processes followed by the image editing professionals who solve - and the perpetrators who commit - a variety of crimes. Even if you've never considered altering an image or becoming a crime scene investigator, you'll get a kick out of discovering the how and why behind both famous and common acts of image fraud with "Adobe Photoshop Forensics!"

Just when we thought we knew everything about Lewis Carroll, here comes a highly original biography that will appeal to Alice fans everywhere. Fascinated by the inner life of Charles Lutwidge Dodson, Robin Wilson, a Carroll scholar and a noted mathematics professor, has produced this revelatory book—filled with more than one hundred striking and often playful illustrations—that examines the many inspirations and sources for Carroll's fantastical writings, mathematical and otherwise. As Wilson demonstrates, Carroll—who published serious, if occasionally eccentric, works in the fields of geometry, logic, and algebra—made significant contributions to subjects as varied as voting patterns and the design of tennis tournaments, in the process creating imaginative recreational puzzles based on mathematical ideas. In the tradition of Sylvia Nasar's A Beautiful Mind and Andrew Hodges's Alan Turing, this is an engaging look at the incredible genius of one of mathematics' and literature's most enigmatic minds. 100 illustrations
