Mathematicians solve equations, or try to. But sometimes the solutions are not as interesting as the beautiful symmetric patterns that lead to them. Written in a friendly style for a general audience, Fearless Symmetry is the first popular math book to discuss these elegant and mysterious patterns and the ingenious techniques mathematicians use to uncover them. Hidden symmetries were first discovered nearly two hundred years ago by French mathematician évariste Galois. They have been used extensively in the oldest and largest branch of mathematics--number theory--for such diverse applications as acoustics, radar, and codes and ciphers. They have also been employed in the study of Fibonacci numbers and to attack well-known problems such as Fermat's Last Theorem, Pythagorean Triples, and the ever-elusive Riemann Hypothesis. Mathematicians are still devising techniques for teasing out these mysterious patterns, and their uses are limited only by the imagination. The first popular book to addre

This book was first published in 2007 and is a study of theastronomical culture of sixteenth-century Europe. It examines, inparticular, the ways in which members of the nascent internationalastronomical community shared information, attracted patronage andrespect for their work, and conducted their disputes. Particularattention is paid to the Danish astronomer Tycho Brahe (1546–1601),known for his observatory Uraniborg on the island of Hven, hisoperation of a printing press, and his development of a thirdworld-system to rival those of Ptolemy and Copernicus. Adam Mosleyexamines the ways in which Tycho interacted with a Europe-widenetwork of scholars, looking not only at how he constructed hisreputation through print, but also at his use of correspondence andthe role that instruments played as vehicles for data and theories.The book will be of interest to historians of science, historiansof the book, and historians of early modern culture in general.

This book explores new ground in social movements by analyzingan escalatingspiral of tension between the Patriot movement and thestate centered on themutual framing of conflict as "warfare." Byexamining the social construction of"warfare" as a principal *or frame defining the movement-state dynamic,Stuart A. Wrightexplains how this highly charged confluence of a warnarrativeengendered a kind of symbiosis leading to the escalationof a mutual threat thatculminated in the Oklahoma City bombing.Wright offers a unique perspectiveon the events leading up to thebombing because he served as a consultant toTimothy McVeigh'sdefense team and draws on primary data based on face-to-faceinterviews with McVeigh. The book contends that McVeigh wasfirmlyentrenched in the Patriot movement and was part of a networkof "warriorcells" that planned and implemented the bombing. Assuch, the bombing mustbe viewed through the lens of a socialmovement framework in order to fullyunderstand the incident and therole played by McVeigh.

"The most talked-about education book this semester."—New York Times Based on a series of controversial Wall Street Journal op-eds,this landmark manifesto gives voice to what everyone knows abouttalent, ability, and intelligence but no one wants to admit. Withfour truths as his framework, Charles Murray, the bestsellingcoauthor of The Bell Curve, sweeps away the hypocrisy, wishfulthinking, and upside-down priorities that grip America’seducational establishment. ?Ability varies. Children differ in their ability to learn,but America’s educational system does its best to ignore this. ?Half of the children are below average. Many children cannotlearn more than rudimentary reading and math. Yet decades ofpolicies have required schools to divert resources to unattainablegoals. ?Too many people are going to college. Only a fraction ofstudents struggling to get a degree can profit from education atthe college level. ?America’s future depends on how we educate the acade

At the beginning of thetwentieth century, the South Pole was the most coveted prize in thefiercely nationalistic modern age of exploration. In this brilliantdual biography, the award-winning writer Roland Huntford reexaminesevery detail of the great race to the South Pole between Britain'sRobert Scott and Norway's Roald Amundsen. Scott, who died along theway with four of his men only eleven miles from his next cache ofsupplies, became Britain's beloved failure, while Amundsen, who notonly beat Scott to the Pole but returned alive, was largelyforgotten. This account of their race is a gripping, highlyreadable history that captures the driving ambitions of the era andthe complex, often deeply flawed men who were charged with carryingthem out. The Last Place on Earth is the first of Huntford's masterly trilogyof polar biographies. It is also the only work on the subject inthe English language based on the original Norwegian sources, towhich Huntford returned to revise and update this edition.
