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.

Having a clear, compelling vision--and getting buy-in from your team--is essential to effective leadership. If you don't know where you're going, how on earth will you get there? But how do you craft that vision? How do you get others on board? And how do you put that vision into practice at every level of your organization? In The Vision Driven Leader, New York Times bestselling author Michael Hyatt offers six tools for crafting an irresistible vision for your business, rallying your team around the vision, and distilling it into actionable plans that drive results. Based on Michael's 40 years of experience as an entrepreneur and executive, backed by insights from organizational science and psychology, and illustrated by case studies and stories from multiple industries, The Vision Driven Leader takes you step-by-step from why to what and then how. Your business will never be the same.

What does it mean to lead with vision? From LinkedIn Learning Expert, Bonnie Hagemann comes the first book devoted entirely to vision as a key leadership principle. Hagemann and her co-authors delve deeply into the notion that a compelling vision that motivates and inspires is a differentiator for organizations that want to hire and retain talent, be more competitive, and thrive in uncertain times. But a compelling vision on its own is not enough, which is why the authors, sought-after leadership development experts globally, provide readers with detailed analysis of the essential things leaders must do to effectively engage the workforce around that vision: embody courage, forge clarity, build connectedness, and shape culture. Leading with Vision draws on quantitative data from the authors' research of over 400 companies supplemented with real-world examples from thoughtful leaders who exemplify the core principles of leading with vision in established companies, including: Olukai, Bumble Bee, Coresystems, Jimbo's, Bunge, and more. The book also includes an actionable blueprint developed by the authors that leaders and their organizations can implement on day one of their journey.
