This is perhaps the first time we have such a complete firsthand account in which nothing is kept back and there is no departmental “diplomacy.” The author is a nuclear power specialist who worked for a time at the Chernobyl AES and knows it well, just as he is personally acquainted with all the principal participants in the events. By virtue of his official position, he has attended many of the crucial conferences concerning nuclear power plant construction. Immediately after the accident, Medvedev was sent to Chernobyl and had an opportunity to learn a great deal while the trail was still fresh and to see things with his own eyes. He presents many technical details indispensable to understanding the mechanism whereby the accident occurred, he exposes the secrets of bureaucratic relations, he tells about the oversights of scientists and designers, about the disastrous overbearing pressure in the command system, about the violations of glasnost before the accident and in the emergency situation following it that have caused enormous harm. The chronicle of events at Chernobyl in the tragic days of April and May 1986 takes up the central place in the story. The author portrays the behavior and role of numerous participants in the drama, of real living people with their shortcomings and virtues, their doubts, their weaknesses, their illusions, and their heroism alongside the nuclear monster that had gone out of control. It is not possible to read about this without the deepest emotion. We knew about the exploits of the firemen. The author tells about the heroism of the electricians, the turbine specialists, the operators, and other workers at the station who prevented the accident from taking on greater proportions.

    Hermann Weyl explores the concept of symmetry beginning with the idea that it represents a harmony of proportions, and gradually departs to examine its more abstract varieties and manifestations--as bilateral, translatory, rotational, ornamental, and crystallographic. Weyl investigates the general abstract mathematical idea underlying all these special forms, using a wealth of illustrations as support. Symmetry is a work of seminal relevance that explores the great variety of applications and importance of symmetry.

    The new edition provides invitations - not requirements - to use technology, as well as new conceptual problems, and new projects that focus on writing and working in teams.

    This book offers an excellent foundation in ethical decision-making for current and future business managers and IT professionals.

    In this indispensable volume, a primer for the information age, Hans Christian von Baeyer presents a clear description of what information is, how concepts of its measurement, meaning, and transmission evolved, and what its ever-expanding presence portends for the future. Information is poised to replace matter as the primary stuff of the universe, von Baeyer suggests; it will provide a new basic framework for describing and predicting reality in the twenty-first century. Despite its revolutionary premise, von Baeyer's book is written simply in a straightforward fashion, offering a wonderfully accessible introduction to classical and quantum information. Enlivened with anecdotes from the lives of philosophers, mathematicians, and scientists who have contributed significantly to the field, Information conducts readers from questions of subjectivity inherent in classical information to the blurring of distinctions between computers and what they measure or store in our quantum age. A great advance in our efforts to define and describe the nature of information, the book also marks an important step forward in our ability to exploit information--and, ultimately, to transform the nature of our relationship with the physical universe.

    But for those of us who left math behind in high school, the numbers and figures hurled at us as we go about our days can sometimes leave us scratching our heads and feeling as if we’re fumbling through a mathematical minefield. In this eye-opening and extraordinarily accessible book, mathemati­cian Kit Yates illuminates hidden principles that can help us understand and navigate the chaotic and often opaque surfaces of our world. In The Math of Life and Death, Yates takes us on a fascinating tour of everyday situations and grand-scale applications of mathematical concepts, including exponential growth and decay, optimization, statistics and probability, and number systems. Along the way he reveals the mathematical undersides of controversies over DNA testing, medical screening results, and historical events such as the Chernobyl disaster and the Amanda Knox trial. Readers will finish this book with an enlightened perspective on the news, the law, medicine, and history, and will be better equipped to make personal decisions and solve problems with math in mind, whether it’s choosing the shortest checkout line at the grocery store or halting the spread of a deadly disease.
