When teenager Bobby Blume arrives home late one night to discover his parents' blood-splattered bodies, police brand the midsummer tragedy a murder-suicide. But despite the couple's long history of domestic abuse, one police detective isn't convinced, suspecting the boy himself may be the real killer. Unanswered questions about the double slayings linger into the fall when the enigmatic young teen transfers to Halcyon High School where he's immediately targeted by a gang of relentless bullies. Not long after, the school is shaken to its core when a posting on the internet threatens Halcyon with a Columbine-style bloodbath and the bullied Blume becomes a prime suspect. But Bobby is also a gifted athlete, finding solace in long distance running and an unlikely ally in high school teacher Mitchell Grey, a thirteen year veteran of the classroom trenches. Grey, long frustrated by the school's inept administrative bureaucracy, the onslaught of immigrant students, overcrowded classrooms, endless standardized testing, an escalating floodtide of learning disabled students, and the crippling effects of an overbearing ADHD industry, is himself a conflicted man in the midst of his own career and personal crises. Threats of violence and bloodshed still hang in the air at Homecoming and a climactic cross-country meet. If the hapless Bobby can somehow outrace the storied Cruiser Kasewort, the state's premiere distance runner, he could win a college scholarship and, perhaps, the heart of fickle dream girl Becky Matthews. In the end it's left to Grey, with help from wisecracking math teacher Stan Cassidy, jovial track Coach Tyrone Tonny, and starry-eyed young guidance counselor Katy O'Conner, to uncover the truth about the troubled teen and, in an action-packed finale, come to terms with the broken pieces of his own life in An Educated Guess.

An antidote to mathematical rigor mortis, teaching how to guess answers without needing a proof or an exact calculation. In problem solving, as in street fighting, rules are for fools: do whatever works—don't just stand there! Yet we often fear an unjustified leap even though it may land us on a correct result. 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.

A NEW YORK TIMES BESTSELLER "A memoir as fierce, freewheeling, and passionate as her music." --O, the Oprah magazine A memoir by the celebrated singer-songwriter and social activist Ani DiFranco In her new memoir, No Walls and the Recurring Dream, Ani DiFranco recounts her early life from a place of hard-won wisdom, combining personal expression, the power of music, feminism, political activism, storytelling, philanthropy, entrepreneurship, and much more into an inspiring whole. In these frank, honest, passionate, and often funny pages is the tale of one woman's eventful and radical journey to the age of thirty. Ani's coming of age story is defined by her ethos of fierce independence--from being an emancipated minor sleeping in a Buffalo bus station, to unwaveringly building a career through appearances at small clubs and festivals, to releasing her first album at the age of 18, to consciously rejecting the mainstream recording industry and creating her own label, Righteous Babe Records. In these pages, as in life, she never hesitates to question established rules and expectations, maintaining a level of artistic integrity that has inspired and challenged more than a few. Ani continues to be a major touring and recording artist as well as a celebrated activist and feminist, standing as living proof that you can overcome all personal and societal obstacles to be who you are and to follow your dreams.

It is the year 4022; all of the ancient country of Usa has been buried under many feet of detritus from a catastrophe that occurred back in 1985. Imagine, then, the excitement that Howard Carson, an amateur archeologist at best, experienced when in crossing the perimeter of an abandoned excavation site he felt the ground give way beneath him and found himself at the bottom of a shaft, which, judging from the DO NOT DISTURB sign hanging from an archaic doorknob, was clearly the entrance to a still-sealed burial chamber. Carson's incredible discoveries, including the remains of two bodies, one of then on a ceremonial bed facing an altar that appeared to be a means of communicating with the Gods and the other lying in a porcelain sarcophagus in the Inner Chamber, permitted him to piece together the whole fabric of that extraordinary civilization.

#1 NEW YORK TIMES, WALL STREET JOURNAL, AND BOSTON GLOBE BESTSELLER • One of the most acclaimed books of our time: an unforgettable memoir about a young woman who, kept out of school, leaves her survivalist family and goes on to earn a PhD from Cambridge University “Extraordinary . . . an act of courage and self-invention.”—The New York Times NAMED ONE OF THE TEN BEST BOOKS OF THE YEAR BY THE NEW YORK TIMES BOOK REVIEW • ONE OF PRESIDENT BARACK OBAMA’S FAVORITE BOOKS OF THE YEAR • BILL GATES’S HOLIDAY READING LIST • FINALIST: National Book Critics Circle’s Award In Autobiography and John Leonard Prize For Best First Book • PEN/Jean Stein Book Award • Los Angeles Times Book Prize Born to survivalists in the mountains of Idaho, Tara Westover was seventeen the first time she set foot in a classroom. Her family was so isolated from mainstream society that there was no one to ensure the children received an education, and no one to intervene when one of Tara’s older brothers became violent. When another brother got himself into college, Tara decided to try a new kind of life. Her quest for knowledge transformed her, taking her over oceans and across continents, to Harvard and to Cambridge University. Only then would she wonder if she’d traveled too far, if there was still a way home. “Beautiful and propulsive . . . Despite the singularity of [Westover’s] childhood, the questions her book poses are universal: How much of ourselves should we give to those we love? And how much must we betray them to grow up?”—Vogue NAMED ONE OF THE BEST BOOKS OF THE YEAR BY The Washington Post • O: The Oprah Magazine • Time • NPR • Good Morning America • San Francisco Chronicle • The Guardian • The Economist • Financial Times • Newsday • New York Post • theSkimm • Refinery29 • Bloomberg • Self • Real Simple • Town & Country • Bustle • Paste • Publishers Weekly • Library Journal • LibraryReads • Book Riot • Pamela Paul, KQED • New York Public Library

Mobile robotics has until now focused on issues like design of controllers and robot hardware. It is now ready to embrace theoretical methods from dynamical systems theory, statistics and system identification to produce a formalized approach based on quantitative analyses and computer models of the interaction between robot, task and environment. This book is a step towards a theoretical understanding of the operation of autonomous mobile robots. It presents cutting-edge research on the application of chaos theory, parametric and non-parametric statistics and dynamical systems theory in this field. Practical examples and case studies show how robot behaviour can be logged, analysed, interpreted and modelled, aiding design of controllers, analysis of agent behaviour and verification of results. As the first book to apply advanced scientific methods to mobile robots it will interest researchers, lecturers and post-graduate students in robotics, artificial intelligence and cognitive science.

Las Vegas. Three bodies have been found, clearly the victims of a serial killer. The police are baffled and there are no clues to the identity of this dangerous psychopath with messianic delusions.

Informatics and the Foundations of Legal Reasoning represents a close collaboration between a wide range of disciplines and countries. Fourteen papers, together with a long analytical introduction by the editors, were selected from the contributions of legal theorists, computer scientists, philosophers and logicians who were members of an International Working Group supported by the European Commission. The Group was mandated to work towards determining how far the law is amenable to formal modeling, and in what ways computers might assist legal thinking and practice. The book is the result of discussions held by the Group over two and half years. It will help students and researchers from different backgrounds to focus on a common set of topics of increasing general interest. It embodies the results of work in progress and suggests many issues for further discussion. A stimulating text for undergraduate and graduate courses in law, philosophy and computer science departments, as well as for those interested in the place of computers in legal practice, especially at the international level.
