In this book, Chris Bernhardt offers an introduction to quantum computing that is accessible to anyone who is comfortable with high school mathematics. He explains qubits, entanglement, quantum teleportation, quantum algorithms, and other quantum-related topics as clearly as possible for the general reader. Bernhardt, a mathematician himself, simplifies the mathematics as much as he can and provides elementary examples that illustrate both how the math works and what it means.Bernhardt introduces the basic unit of quantum computing, the qubit, and explains how the qubit can be measured; discusses entanglement--which, he says, is easier to describe mathematically than verbally--and what it means when two qubits are entangled (citing Einstein's characterization of what happens when the measurement of one entangled qubit affects the second as "spooky action at a distance"); and introduces quantum cryptography. He recaps standard topics in classical computing--bits, gates, and logic--and describes Edward Fredkin's ingenious billiard ball computer. He defines quantum gates, considers the speed of quantum algorithms, and describes the building of quantum computers. By the end of the book, readers understand that quantum computing and classical computing are not two distinct disciplines, and that quantum computing is the fundamental form of computing. The basic unit of computation is the qubit, not the bit.

    It had a population of sixty million people spread across lands encircling the Mediterranean and stretching from northern England to the sun-baked banks of the Euphrates, and from the Rhine to the North African coast. It was, above all else, anempire of force--employing a mixture of violence, suppression, order, and tactical use of power to develop an astonishingly uniform culture.Here, historian Christopher Kelly covers the history of the Empire from Augustus to Marcus Aurelius, describing the empire's formation, and its political, religious, cultural, and social structures. It looks at the daily lives of the Empire's people: both those in Rome as well as those living in itsfurthest colonies. Romans used astonishing logistical feats, political savvy, and military oppression to rule their vast empire. This Very Short Introduction examines how they romanised the cultures they conquered, imposing their own culture in order to subsume them completely. The book also looksat how the Roman Empire has been considered and depicted in more recent times, from the writings of Edward Gibbon to the Hollywood blockbuster Gladiator. It will prove a valuable introduction for readers interested in classical history.

    Now, in The American Presidency, presidential authority Charles O. Jones provides invaluable background to the current controversy, in a compact, reliable guide to the office of the chief executive.This marvelously concise survey is packed with information about the presidency, some of it quite surprising. We learn, for example, that the Founders adopted the word president over governor and other alternatives because it suggested a light hand, as in one who presides, rather than rules. Indeed, the Constitutional Convention first agreed to a weak chief executive elected by congress for one seven-year term, later calling for independent election and separation of powers. Jones sheds much light on how assertive leaders, such as Andrew Jackson, Theodore Roosevelt, and FDR enhanced the power of the presidency, and illuminating how such factors as philosophy (Reagan's anti-Communist conservatism), the legacy of previous presidencies (Jimmy Carter following Watergate), relations with Congress, and the impact of outside events have all influenced presidential authority. He also explores the rise of federal power and the dramatic expansion of federal agencies, showing how the president takes a direct hand in this vast bureaucracy, and he examines the political process of selecting presidents, from the days of deadlocked conventions to the rise of the primary after World War II.In 200 years, he writes, the presidency had changed from that of a person--Washington followed by Adams, then Jefferson--to a presidential enterprise with a cast of thousands. Jones explains how this remarkable expansion has occurred and where it may lead in the future.About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics.

    But when did this essential part of our lives begin? Why do we all write differently and how did writing evolve into what we use today? All of these questions are answered in this Very Short Introduction. Andrew Robinson tells the fascinating story of the history of writing, shedding light on its development and examining the enormous variety of writing and scripts we use today. Starting with the origins of writing five thousand years ago, with cuneiform and Egyptian hieroglyphs, Robinson explains how these early forms developed into hundreds of scripts, including the Roman alphabet and Chinese characters. He reveals how the modern writing symbols and abbreviations we take for granted today--including airport signage and text messaging--resemble ancient ones much more closely than we might think. The book also includes a chronology of events from 3300 BC to AD 2000, a list of titles for further reading, and an index.About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics.

    The style is lively and accessible without sacrificing detail or depth. An introductory chapter discusses Sade's life and the links between that and his work. Relying on the many letters he wrote to his wife and lawyer from prison and on other authentic, contemporary evidence, it attempts to disentangle this life from the various myths that Sade's demonic reputation has engendered throughout the nineteenth and twentieth centuries. This initial chapter also reviews the critical corpus or reception of the work since Sade's times up to the present, and reassesses his status as an extra-canonical writer. The following six chapters provide broad coverage of Sade's main intellectual and creative activities, showing how all can be seen as the expression of a veritable cult of the body, a veneration of the physical, and the sexual as channels of transcendence.
