    A life of the Genoese weaver's son who sought to prove the world is round, telling how he studied map-making in Portugal, waited long years for financial and material support from Isabella of Spain, and finally made four voyages to the New World.

    The study of type systems--and of programming languages from a type-theoretic perspective--has important applications in software engineering, language design, high-performance compilers, and security.This text provides a comprehensive introduction both to type systems in computer science and to the basic theory of programming languages. The approach is pragmatic and operational; each new concept is motivated by programming examples and the more theoretical sections are driven by the needs of implementations. Each chapter is accompanied by numerous exercises and solutions, as well as a running implementation, available via the Web. Dependencies between chapters are explicitly identified, allowing readers to choose a variety of paths through the material.The core topics include the untyped lambda-calculus, simple type systems, type reconstruction, universal and existential polymorphism, subtyping, bounded quantification, recursive types, kinds, and type operators. Extended case studies develop a variety of approaches to modeling the features of object-oriented languages.

    The algorithms you'll use most often as a programmer have already been discovered, tested, and proven. If you want to take a hard pass on Knuth's brilliant but impenetrable theories and the dense multi-page proofs you'll find in most textbooks, this is the book for you. This fully-illustrated and engaging guide makes it easy for you to learn how to use algorithms effectively in your own programs.Grokking Algorithms is a disarming take on a core computer science topic. In it, you'll learn how to apply common algorithms to the practical problems you face in day-to-day life as a programmer. You'll start with problems like sorting and searching. As you build up your skills in thinking algorithmically, you'll tackle more complex concerns such as data compression or artificial intelligence. Whether you're writing business software, video games, mobile apps, or system utilities, you'll learn algorithmic techniques for solving problems that you thought were out of your grasp. For example, you'll be able to:Write a spell checker using graph algorithmsUnderstand how data compression works using Huffman codingIdentify problems that take too long to solve with naive algorithms, and attack them with algorithms that give you an approximate answer insteadEach carefully-presented example includes helpful diagrams and fully-annotated code samples in Python. By the end of this book, you will know some of the most widely applicable algorithms as well as how and when to use them.

    What is Poetry

    

    Bruce Lesh believes that this is due to the way we teach history—lecture and memorization. Over the last fifteen years, Bruce has refined a method of teaching history that mirrors the process used by historians, where students are taught to ask questions of evidence and develop historical explanations. And now in his new book “Why Won’t You Just Tell Us the Answer?” he shows teachers how to successfully implement his methods in the classroom.Students may think they want to be given the answer. Yet, when they are actively engaged in investigating the past—the way professional historians do—they find that history class is not about the boring memorization of names, dates, and facts. Instead, it’s challenging fun. Historical study that centers on a question, where students gather a variety of historical sources and then develop and defend their answers to that question, allows students to become actual historians immersed in an interpretive study of the past.Each chapter focuses on a key concept in understanding history and then offers a sample unit on how the concept can be taught. Readers will learn about the following: • Exploring Text, Subtext, and Context: President Theodore Roosevelt and the Panama Canal • Chronological Thinking and Causality: The Rail Strike of 1877 • Multiple Perspectives: The Bonus March of 1932 • Continuity and Change Over Time: Custer’s Last Stand • Historical Significance: The Civil Rights Movement • Historical Empathy: The Truman-MacArthur DebateBy the end of the book, teachers will have learned how to teach history via a lens of interpretive questions and interrogative evidence that allows both student and teacher to develop evidence-based answers to history’s greatest questions.

    And most are finding that the answer is “yes.” If they want their students to learn complex new concepts in different disciplines, they often have to help their students become better readers.Building on the experiences gained in her own language arts classroom as well as those of colleagues in different disciplines, Cris Tovani, author of I Read It, but I Don't Get It, takes on the challenge of helping students apply reading comprehension strategies in any subject. In Do I Really Have to Teach Reading?, Cris shows how teachers can expand on their content expertise to provide instruction students need to understand specific technical and narrative texts. The book includes:examples of how teachers can model their reading process for students;ideas for supplementing and enhancing the use of required textbooks;detailed descriptions of specific strategies taught in context;stories from different high school classrooms to show how reading instruction varies according to content;samples of student work, including both struggling readers and college-bound seniors;a variety of “comprehension constructors”: guides designed to help students recognize and capture their thinking in writing while reading;guidance on assessing students;tips for balancing content and reading instruction.Cris's humor, honesty, and willingness to share her own struggles as a teacher make this a unique take on content reading instruction that will be valuable to reading teachers as well as content specialists.
