Casti contemplates an imaginary evening of intellectual inquiry—a sort of “My Dinner with” not Andre, but five of the most brilliant thinkers of the twentieth century.Imagine, if you will, one stormy summer evening in 1949, as novelist and scientist C. P. Snow, Britain’s distinguished wartime science advisor and author of The Two Cultures, invites four singular guests to a sumptuous seven-course dinner at his alma mater, Christ’s College, Cambridge, to discuss one of the emerging scientific issues of the day: Can we build a machine that could duplicate human cognitive processes? The distinguished guest list for Snow’s dinner consists of physicist Erwin Schrodinger, inventor of wave mechanics; Ludwig Wittgenstein, the famous twentieth-century philosopher of language, who posited two completely contradictory theories of human thought in his lifetime; population geneticist/science popularizer J.B.S. Haldane; and Alan Turing, the mathematician/codebreaker who formulated the computing scheme that foreshadowed the logical structure of all modern computers. Capturing not only their unique personalities but also their particular stands on this fascinating issue, Casti dramatically shows what each of these great men might have argued about artificial intelligence, had they actually gathered for dinner that midsummer evening.With Snow acting as referee, a lively intellectual debate unfolds. Philosopher Wittgenstein argues that in order to become conscious, a machine would have to have life experiences similar to those of human beings—such as pain, joy, grief, or pleasure. Biologist Haldane offers the idea that mind is a separate entity from matter, so that regardless of how sophisticated the machine, only flesh can bond with that mysterious force called intelligence. Both physicist Schrodinger and, of course, computer pioneer Turing maintain that it is not the substance, but rather the organization of that substance, that makes a mind conscious.With great verve and skill, Casti recreates a unique and thrilling moment of time in the grand history of scientific ideas. Even readers who have already formed an opinion on artificial intelligence will be forced to reopen their minds on the subject upon reading this absorbing narrative. After almost four decades, the solutions to the epic scientific and philosophical problems posed over this meal in C. P. Snow’s old rooms at Christ’s College remains tantalizingly just out of reach, making this adventure into scientific speculation as valid today as it was in 1949.

    Now, from a Silicon Valley hero and bestselling technology writer comes a pointed critique of the hype surrounding computers and their real benefits, especially in education. In High-Tech Heretic, Clifford Stoll questions the relentless drumbeat for "computer literacy" by educators and the computer industry, particularly since most people just use computers for word processing and games--and computers become outmoded or obsolete much sooner than new textbooks or a good teacher.As one who loves computers as much as he disdains the inflated promises made on their behalf, Stoll offers a commonsense look at how we can make a technological world better suited for people, instead of making people better suited to using machines.

    Every religion has angels, Sylvia tells us. Different from spirit guides, angels are spiritual messengers who are available to help us if we will simply ask for their assistance. Sylvia goes on to discuss the properties of angels; the true nature of God, good, evil, and the Other Side; and explains how we can overcome guilt, accept ourselves, and thereby understand our own particular “contract.” In the second half of the program, Sylvia leads a meditation that invokes the presence of our angels and individual spirit guides, and invites them to communicate with us. We feel their protection, receive their healing, and with Sylvia’s encouragement, learn how to ask them for the help we desire.

    In this guide for students, each equation is the subject of an entire chapter, with detailed, plain-language explanations of the physical meaning of each symbol in the equation, for both the integral and differential forms. The final chapter shows how Maxwell's equations may be combined to produce the wave equation, the basis for the electromagnetic theory of light. This book is a wonderful resource for undergraduate and graduate courses in electromagnetism and electromagnetics. A website hosted by the author at www.cambridge.org/9780521701471 contains interactive solutions to every problem in the text as well as audio podcasts to walk students through each chapter.

    Book is unique in its emphasis on the frequency approach and its use in the solution of problems. Contents include: Fundamentals and Algorithms; Polynomial Approximation — Classical Theory; Fourier Approximation — Modern Theory; and Exponential Approximation.

    Now, in her latest book, Core Light Healing, her work continues with revolutionary new information on working with the creative process and the fourth level. The fourth-level, or astral, world bridges the creative pulse from the physical to the higher levels of reality and manifestation. Core Light Healing also chronicles Barbara Brennan’s life journey and personal experiences.In Core Light Healing you will discover: The nature of the creative process from the Human Energy Consciousness perspective How each of us creates blocks in our energy fields; how blocks look, interact, and ultimately cause dysfunction in our lives; and the process involved in the clearing of blocks and releasing our creative potential How to develop and work with High Sense Perception and its role in facilitating the clearing of blocks in our energy fields The nature of fourth-level reality and its vital role in the creative process The fourth level as it relates to healing relationships and the cord connections that underlie those relationships And much more Complete with full-color and black-and-white illustrations, Core Light Healing offers to take you on a journey to create the life you have always imagined.

    Borg & John Dominic Crossan reveal a radical & little-known Jesus. As both authors reacted to & responded to questions about Mel Gibson's blockbuster The Passion of the Christ, they discovered that many Christians are unclear on the details of events during the week leading up to Jesus' crucifixion. Using Mark's gospel as a guide, they present a day-by-day account of Jesus' final week of life. They begin their story on Palm Sunday with two triumphal entries into Jerusalem. The 1st entry, that of Roman governor Pontius Pilate leading Roman soldiers into the city, symbolized military strength. The 2nd heralded a new kind of moral hero who was praised by the people as he rode in on a humble donkey. The Jesus introduced herein is this new moral hero, a more dangerous Jesus than the one enshrined in the church's traditional teachings. The Last Week depicts Jesus giving up his life to protest power without justice & to condemn the rich who lack concern for the poor. In this vein, at the end of the week Jesus marches up Calvary, offering himself as a model for others to do the same when confronted by similar issues. Informed, challenged & inspired, we not only meet the historical Jesus, but meet a new Jesus who engages & invites us to follow him.
