Book Description
In 1936, when he was just twenty-four years old, Alan Turing wrote a remarkable paper in which he outlined the theory of computation, laying out the ideas that underlie all modern computers. This groundbreaking and powerful theory now forms the basis of computer science. In Turing's Vision, Chris Bernhardt explains the theory, Turing's most important contribution, for the general reader. Bernhardt argues that the strength of Turing's theory is its simplicity, and that, explained in a straightforward manner, it is eminently understandable by the nonspecialist. As Marvin Minsky writes, "The sheer simplicity of the theory's foundation and extraordinary short path from this foundation to its logical and surprising conclusions give the theory a mathematical beauty that alone guarantees it a permanent place in computer theory." Bernhardt begins with the foundation and systematically builds to the surprising conclusions. He also views Turing's theory in the context of mathematical history, other views of computation (including those of Alonzo Church), Turing's later work, and the birth of the modern computer. In the paper, "On Computable Numbers, with an Application to the Entscheidungsproblem," Turing thinks carefully about how humans perform computation, breaking it down into a sequence of steps, and then constructs theoretical machines capable of performing each step. Turing wanted to show that there were problems that were beyond any computer's ability to solve; in particular, he wanted to find a decision problem that he could prove was undecidable. To explain Turing's ideas, Bernhardt examines three well-known decision problems to explore the concept of undecidability; investigates theoretical computing machines, including Turing machines; explains universal machines; and proves that certain problems are undecidable, including Turing's problem concerning computable numbers.

Book Description
In this interdisciplinary work, William L. Davis examines Joseph Smith's 1829 creation of the Book of Mormon, the foundational text of the Latter Day Saint movement. Positioning the text in the history of early American oratorical techniques, sermon culture, educational practices, and the passion for self-improvement, Davis elucidates both the fascinating cultural context for the creation of the Book of Mormon and the central role of oral culture in early nineteenth-century America. Drawing on performance studies, religious studies, literary culture, and the history of early American education, Davis analyzes Smith's process of oral composition. How did he produce a history spanning a period of 1,000 years, filled with hundreds of distinct characters and episodes, all cohesively tied together in an overarching narrative? Eyewitnesses claimed that Smith never looked at notes, manuscripts, or books—he simply spoke the words of this American religious epic into existence. Judging the truth of this process is not Davis's interest. Rather, he reveals a kaleidoscope of practices and styles that converged around Smith's creation, with an emphasis on the evangelical preaching styles popularized by the renowned George Whitefield and John Wesley.

Book Description
Blending numerous heritages, wisdoms, and teachings, this powerfully wrought book encourages people to take charge of their lives, heal themselves, and grow. Movingly rendered, The Book of the Vision Quest is for all who long for renewal and personal transformation. In this revised edition—with two new chapters and added tales from vision questers—Steven Foster recounts his experiences guiding contemporary seekers. He recreates an ancient rite of passage—that of “dying,” “passing through,” and “being reborn”—known as a vision quest. A sacred ceremony that culminates in a three-day, three-night fast, alone, in a place of natural power, the vision quest is a mystical, practical, and intensely personal journey of self-knowledge.

Book Description
The church is more than a building - it is an assembly of people joined together across distances and even through time to fulfill God’s purposes in the world. Each local gathering of that assembly needs a vision to help its members accomplish the work God has called them to do. But how do you inspire your church to create and follow through on a vision? Mike Milton provides tested, biblical ideas to get everyone in the church involved in a plan to help the congregation grow. Each chapter develops an awareness of what needs to be done, provides questions for review, and includes prayers by elders and ministers of churches that have put these ideas to use.

Book Description
The Magazine of Photography and Ideas. As the United States navigates a political moment defined by the close of the Obama era and the rise of #BlackLivesMatter activism, Aperture magazine releases "Vision & Justice," a special issue guest edited by Sarah Lewis, the distinguished author and art historian, addressing the role of photography in the African American experience. "Vision & Justice" includes a wide span of photographic projects by such luminaries as Lyle Ashton Harris, Annie Leibovitz, Sally Mann, Jamel Shabazz, Lorna Simpson, Carrie Mae Weems and Deborah Willis, as well as the brilliant voices of an emerging generation―Devin Allen, Awol Erizku, LaToya Ruby Frazier, Deana Lawson and Hank Willis Thomas, among many others. These portfolios are complemented by essays from some of the most influential voices in American culture including contributions by celebrated writers, historians, and artists such as Vince Aletti, Teju Cole, Henry Louis Gates, Jr., Margo Jefferson, Wynton Marsalis and Claudia Rankine. "Vision and Justice" features two covers. This issue comes with an image by Richard Avedon, Martin Luther King, Jr., civil rights leader, with his father, Martin Luther King, Baptist minister, and his son, Martin Luther King III, Atlanta, Georgia, March 22, 1963.
