  gemstone shares name with programming language: Stone of Kings Gerard Helferich, 2012-12-21 A book perfectly timed for the re-setting of the Maya calendar in 2012.... Part history, popular science, armchair travel, and real-life treasure hunt, this is the story of pre-Columbian jade—the precious stone revered by ancient Aztecs, Incans, and Maya—and the scientists, collectors, explorers and entrepreneurs who have been searching for the mythical jade mines for more than a century. “A compelling tale.... This well-focused and well-told account brings America’s most mythologized gemstone into sharp relief.” —Wall Street Journal “[T]he story of the search for the long-vanished mines of the Mayas . . . [with] engaging digressions into plate tectonics, the technology of jade carving and the brutal history of the regimes of a succession of Guatemalan generals. . . . [Prospectors] Ridinger and Johnson endured earthquakes, coups, kidnapping, even civil war. But eventually they stumbled upon huge blocks of the alluring, elusive stone.” —New York Times Book Review Selected as an Indie Next List “Great Read” “The search for the sources of this mysterious rock reads like detective fiction, and involves geologists, archaeologists, entrepreneurs, poachers, and a host of other characters, but it’s all true. A wonderful read!” —Michael D. Coe, author of Breaking the Maya Code

  gemstone shares name with programming language: Definiteness across languages Ana Aguilar-Guevara , Julia Pozas Loyo , Violeta Vázquez-Rojas Maldonado , 2019 Definiteness has been a central topic in theoretical semantics since its modern foundation. However, despite its significance, there has been surprisingly scarce research on its cross-linguistic expression. With the purpose of contributing to filling this gap, the present volume gathers thirteen studies exploiting insights from formal semantics and syntax, typological and language specific studies, and, crucially, semantic fieldwork and cross-linguistic semantics, in order to address the expression and interpretation of definiteness in a diverse group of languages, most of them understudied. The papers presented in this volume aim to establish a dialogue between theory and data in order to answer the following questions: What formal strategies do natural languages employ to encode definiteness? What are the possible meanings associated to this notion across languages? Are there different types of definite reference? Which other functions (besides marking definite reference) are associated with definite descriptions? Each of the papers contained in this volume addresses at least one of these questions and, in doing so, they aim to enrich our understanding of definiteness.

  gemstone shares name with programming language: The Language of Doctor Who Jason Barr, Camille D. G. Mustachio, 2014-05-15 In a richly developed fictional universe, Doctor Who, a wandering survivor of a once-powerful alien civilization, possesses powers beyond human comprehension. He can bend the fabric of time and space with his TARDIS, alter the destiny of worlds, and drive entire species into extinction. The good doctor’s eleven “regenerations” and fifty years’ worth of adventures make him the longest-lived hero in science-fiction television. In The Language of Doctor Who: From Shakespeare to Alien Tongues, Jason Barr and Camille D. G. Mustachio present several essays that use language as an entry point into the character and his universe. Ranging from the original to the rebooted television series—through the adventures of the first eleven Doctors—these essays explore how written and spoken language have been used to define the Doctor’s ever-changing identities, shape his relationships with his many companions, and give him power over his enemies—even the implacable Daleks. Individual essays focus on fairy tales, myths, medical-travel narratives, nursery rhymes, and, of course, Shakespeare. Contributors consider how the Doctor’s companions speak with him through graffiti, how the Doctor himself uses postmodern linguistics to communicate with alien species, and how language both unites and divides fans of classic Who and new Who as they try to converse with each other. Broad in scope, innovative in approach, and informed by a deep affection for the program, TheLanguage of Doctor Who will appeal to scholars of science fiction, television, and language, as well as to fans looking for a new perspective on their favorite Time Lord.

  gemstone shares name with programming language: The Pattern On The Stone W. Daniel Hillis, 2014-12-09 Most people are baffled by how computers work and assume that they will never understand them. What they don't realize -- and what Daniel Hillis's short book brilliantly demonstrates -- is that computers' seemingly complex operations can be broken down into a few simple parts that perform the same simple procedures over and over again. Computer wizard Hillis offers an easy-to-follow explanation of how data is processed that makes the operations of a computer seem as straightforward as those of a bicycle. Avoiding technobabble or discussions of advanced hardware, the lucid explanations and colorful anecdotes in The Pattern on the Stone go straight to the heart of what computers really do. Hillis proceeds from an outline of basic logic to clear descriptions of programming languages, algorithms, and memory. He then takes readers in simple steps up to the most exciting developments in computing today -- quantum computing, parallel computing, neural networks, and self-organizing systems. Written clearly and succinctly by one of the world's leading computer scientists, The Pattern on the Stone is an indispensable guide to understanding the workings of that most ubiquitous and important of machines: the computer.

  gemstone shares name with programming language: Language, Culture, Computation: Computational Linguistics and Linguistics Nachum Dershowitz, Ephraim Nissan, 2014-12-05 This Festschrift volume is published in Honor of Yaacov Choueka on the occasion of this 75th birthday. The present three-volumes liber amicorum, several years in gestation, honours this outstanding Israeli computer scientist and is dedicated to him and to his scientific endeavours. Yaacov's research has had a major impact not only within the walls of academia, but also in the daily life of lay users of such technology that originated from his research. An especially amazing aspect of the temporal span of his scholarly work is that half a century after his influential research from the early 1960s, a project in which he is currently involved is proving to be a sensation, as will become apparent from what follows. Yaacov Choueka began his research career in the theory of computer science, dealing with basic questions regarding the relation between mathematical logic and automata theory. From formal languages, Yaacov moved to natural languages. He was a founder of natural-language processing in Israel, developing numerous tools for Hebrew. He is best known for his primary role, together with Aviezri Fraenkel, in the development of the Responsa Project, one of the earliest fulltext retrieval systems in the world. More recently, he has headed the Friedberg Genizah Project, which is bringing the treasures of the Cairo Genizah into the Digital Age. This third part of the three-volume set covers a range of topics related to language, ranging from linguistics to applications of computation to language, using linguistic tools. The papers are grouped in topical sections on: natural language processing; representing the lexicon; and neologisation.

  gemstone shares name with programming language: The Inside Story of China's High-tech Industry Yu Zhou, 2008 In the 1980s, China faced the monumental task of creating, from scratch, internationally competitive companies. This challenge was especially daunting in the information and communications technology (ICT) sector. The Inside Story of China's High-Tech Industry describes the emergence and growth of this industry in China through a historically situated analysis of China's leading science park, Beijing's Zhongguancun, also known as China's Silicon Valley. Zhou challenges the prevailing view that foreign multinational corporations and exports are the driving forces for technological progress in less developed countries by arguing that, in the case of China, it is the conjunction of domestic and export markets that has provided the main impetus to technological learning and the development of industry competitiveness. This is the best treatment to date of China's most important innovation region. It will be useful for scholars and students in the fields of economics, regional sciences, geography, planning, sociology, information technology, and business management, as well as for anyone interested in the rise of China and global technological development.
