Metamath is a computer language and an associated computer program for archiving, verifying, and studying mathematical proofs. The Metamath language is simple and robust, with an almost total absence of hard-wired syntax, and we believe that it provides about the simplest possible framework that allows essentially all of mathematics to be expressed with absolute rigor. While simple, it is also powerful; the Metamath Proof Explorer (MPE) database has over 23,000 proven theorems and is one of the top systems in the "Formalizing 100 Theorems" challenge. This book explains the Metamath language and program, with specific emphasis on the fundamentals of the MPE database.
After critiquing chaos, catastrophe, and complexity theories, showing their limitations in the contemporary era, Rich furthers the development of crisis theory and applies the crisis theory approach to biological and social evolution. Treating evolution in the context of crisis theory, he shows that as evolution is both genetic and social, social evolution is an extension of biological evolution. As physical evolution results from problem solving, social evolution develops from the solving of historically significant problems, bringing about, for instance, the post-World War II era of knowledge. In this context, Rich discusses the problems of our era, with an emphasis on the paradox of industrialization and its consequences for wealthy and poor nations alike. The paradox of industrialization is approached in terms of crisis theory and resolved.
Suffering is an ugly word, especially when it's an undisputable part of your own life. It can literally destroy you""mind, body, and spirit. It can control you and turn you into someone you have never been. A loving, spiritual-minded person can become a crooked human being""bitter, desolate, wretched and hopeless but still a human being. Suffering transforms our attitude about ourselves. Instead of us being self-confident and outgoing, it can humble us to the point of wanting to die. It removes the blinders to our vulnerability. It makes us fragile and weak, and it can often bring out the worst in us. A crooked tree is still a tree. Not every tree is tall and straight, nor is any person exempt from pain and suffering. A tornado can take a strong, straight tree and turn it into a pile of rubble with one gust. Just so, none of us expect to experience the pains of loss, disability, and suffering that may come without warning but, in a split second, changes the course of the rest of our lives. Even the strongest and most godly of human beings can reach a breaking point when the tragic events of life crush their human spirit. However, one of the lessons that I have learned through this experience is that God is not finished with me yet; I can find strength in my relationship with him and discover that I still have gifts to offer him. I must remember that God blesses even the crooked tree with what it needs to continue living. When I first wrote this book, I had been in the ministry for thirty years. Now it has been more than fifty-five years. It is proving to be a practical tool for training and use in caregiving rather than a theory or simple narrative. A Cry for Relief will tell you my story and the process of healing through the blessings of spiritual growth and tender caregiving.
The definitive and “utterly absorbing” biography of America’s first news media baron based on newly released private and business documents (Vanity Fair). William Randolph Hearst, known to his staff as the Chief, was a brilliant business strategist and a man of prodigious appetites. By the 1930s, he controlled the largest publishing empire in the United States, including twenty-eight newspapers, the Cosmopolitan Picture Studio, radio stations, and thirteen magazines. He quickly learned how to use this media stronghold to achieve unprecedented political power. The son of a gold miner, Hearst underwent a public metamorphosis from Harvard dropout to political kingmaker; from outspoken populist to opponent of the New Deal; and from citizen to congressman. In The Chief, David Nasaw presents an intimate portrait of the man famously characterized in the classic film Citizen Kane. With unprecedented access to Hearst’s personal and business papers, Nasaw details Heart’s relationship with his wife Millicent and his romance with Marion Davies; his interactions with Hitler, Mussolini, Churchill, and every American president from Grover Cleveland to Franklin Roosevelt; and his acquaintance with movie giants such as Louis B. Mayer, Jack Warner, and Irving Thalberg. An “absorbing, sympathetic portrait of an American original,” The Chief sheds light on the private life of a very public man (Chicago Tribune).
Lovelace provides an introduction to Ada 95, one of the most widely used programming languages in the world. Although the reader is assumed to have a basic understanding of programming, no prior exposure to Ada is assumed and all the basics of the language are covered. The book comprises eighteen chapters each of which is composed of short sections designed to cover a small number of key concept and to provide a test question to check the reader's understanding of the concepts covered. Each chapter then concludes with a small quiz to help ensure that the reader has grasped the principles covered in the chapter. One of Ada 95's new features, its object-oriented facilities, is covered in depth, and all of the essential features of Ada programming are covered thoroughly. In Ada 95 significant enhancements were also added to Ada's ability to interface with other programming languages (such as C, Fortran, and Cobol) and these are covered in one chapter. As a result both students and professional programmers learning Ada for the first time will welcome this new text.
This volume offers a comprehensive history of the Mount Desert Island Biological Laboratory (MDIBL), one of the major marine laboratories in the United States and a leader in using marine organisms to study fundamental physiological concepts. Beginning with its founding as the Harpswell Laboratory of Tufts University in 1898, David H. Evans follows its evolution from a teaching facility to a research center for distinguished renal and epithelial physiologists. He also describes how it became the site of major advances in cytokinesis, regeneration, cardiac and vascular physiology, hepatic physiology, endocrinology and toxicology, as well as studies of the comparative physiology of marine organisms. Fundamental physiological concepts in the context of the discoveries made at the MDIBL are explained and the social and administrative history of this renowned facility is described.
Eminent Harvard astrophysicist David Layzer offers readers a unified theory of natural order and its origins, from the permanence, stability, and orderliness of sub-atomic particles to the evolution of the human mind. Cosmogenesis provides the first extended account of a controversial theory that connects quantum mechanics with the second law of thermodynamics, and presents novel resolutions of longstanding paradoxes in these theories, such as those of Schroedinger's cat and the arrow of time. Layzer's main concerns in the second half of the book are with the philosophical issues surrounding science. He develops a highly original reconciliation of the conflict between traditional scientific determinism and the intuitive notion of individual freedom. He argues that although the elementary processes underlying biological evolution and human development are governed by physical laws, they are nevertheless genuinely creative and unpredictable.
As a study of modern American political culture, Beyond Left and Right gets high marks. This is an extremely readable book. It should quickly become a basic source, especially beneficial to scholars who are researching modern American political history. Lay readers with an interest in American politics should find it informative and accessible. Horowitz explains his ideas in clear direct prose, free of jargon." -- LeRoy Ashby, author of William Jennings Bryan: Champion of Democracy Beyond Left and Right is a sweeping overview of political insurgency in the United States from the 1880s to the present. It is at once a stunning synthesis, drawing on a large number of scholarly works, and an ambitious and original piece of research. The book ranges over diverse individuals and groups that have attacked the established order, from the left and the right, from the Populists of the 1890s to Ross Perot and the religious right of our times, dealing along the way with non-interventionists, Klans, monetary radicals, McCarthyites, Birchers, and Reaganites, among many others.
Toomey brings the brilliant minds of Kip Thorne, Carl Sagan, and Steven Hawking to life as they confront temporal paradoxes and questions of free will, probe black holes and time warps, conceive of parallel universes, and imagine a civilization with the power to send signals into the past.
The Great American Mission traces how America's global modernization efforts during the twentieth century were a means to remake the world in its own image. David Ekbladh shows that the emerging concept of modernization combined existing development ideas from the Depression. He describes how ambitious New Deal programs like the Tennessee Valley Authority became symbols of American liberalism's ability to marshal the social sciences, state planning, civil society, and technology to produce extensive social and economic change. For proponents, it became a valuable weapon to check the influence of menacing ideologies such as Fascism and Communism. Modernization took on profound geopolitical importance as the United States grappled with these threats. After World War II, modernization remained a means to contain the growing influence of the Soviet Union. Ekbladh demonstrates how U.S.-led nation-building efforts in global hot spots, enlisting an array of nongovernmental groups and international organizations, were a basic part of American strategy in the Cold War. However, a close connection to the Vietnam War and the upheavals of the 1960s would discredit modernization. The end of the Cold War further obscured modernization's mission, but many of its assumptions regained prominence after September 11 as the United States moved to contain new threats. Using new sources and perspectives, The Great American Mission offers new and challenging interpretations of America's ideological motivations and humanitarian responsibilities abroad.
How the Hippies Saved Physics gives us an unconventional view of some unconventional people engaged early in the fundamentals of quantum theory. Great fun to read." —Anton Zeilinger, Nobel laureate in physics The surprising story of eccentric young scientists—among them Nobel laureates John Clauser and Alain Aspect—who stood up to convention and changed the face of modern physics. Today, quantum information theory is among the most exciting scientific frontiers, attracting billions of dollars in funding and thousands of talented researchers. But as MIT physicist and historian David Kaiser reveals, this cutting-edge field has a surprisingly psychedelic past. How the Hippies Saved Physics introduces us to a band of freewheeling physicists who defied the imperative to “shut up and calculate” and helped to rejuvenate modern physics. For physicists, the 1970s were a time of stagnation. Jobs became scarce, and conformity was encouraged, sometimes stifling exploration of the mysteries of the physical world. Dissatisfied, underemployed, and eternally curious, an eccentric group of physicists in Berkeley, California, banded together to throw off the constraints of the physics mainstream and explore the wilder side of science. Dubbing themselves the “Fundamental Fysiks Group,” they pursued an audacious, speculative approach to physics. They studied quantum entanglement and Bell’s Theorem through the lens of Eastern mysticism and psychic mind-reading, discussing the latest research while lounging in hot tubs. Some even dabbled with LSD to enhance their creativity. Unlikely as it may seem, these iconoclasts spun modern physics in a new direction, forcing mainstream physicists to pay attention to the strange but exciting underpinnings of quantum theory. A lively, entertaining story that illuminates the relationship between creativity and scientific progress, How the Hippies Saved Physics takes us to a time when only the unlikeliest heroes could break the science world out of its rut.
