The invention of numbers is perhaps the greatest achievement of the human mind-- virtually everything in our lives is digital, numerical, quantified. However, the origins of these numbers has until now been unknown. Amir Aczel crisscrosses the world, scouring dusty, moldy texts, cross-examining self-proclaimed experts with wildly differing theories, to discover where the so-called Hindu-Arabic numerals come from. It is this search that leads him to explore uncharted territory, to go on a grand quest into India, Thailand, Laos, Vietnam, and ultimately into the wilds of Cambodia. There he is blown away to find the earliest zero-- the keystone of our entire system of numbers-- on a crumbling, vine-covered wall of a seventh-century temple adorned with eaten-away erotic sculptures. While on this odyssey, Aczel meets a host of fascinating characters: academics in search of truth, jungle trekkers looking for adventure, surprisingly honest politicians, shameless smugglers, and treacherous archaeological thieves-- who finally reveal where our numbers come from. Aczel takes the reader on a fascinating ride-- Front book jacket flap.

This book provides useful insight into how academics from diverse disciplinary backgrounds, such as science, engineering, technology, social science, policy, design, architecture, built environment, business, and management, have been conducting research into how to realise net zero emissions to address climate change. This book explores the ways in which countries around the world have pledged to achieve net zero emissions through decarbonisation processes. It presents the highest calibre research and impact activities carried out in the UK, Europe, North America, Australia, Asia, and Africa. Such activities include conceptualisation, opportunity identification, specific case studies, demonstration of proof of concepts, provision of evidence, education of the general public, and knowledge transfer to companies. Further to this, the chapters also bring to light personal career journeys to net zero by current and future international research leaders. From this book, readers will gain a full understanding of net zero research via multiple disciplinary pathways, be inspired by personal accounts, and will learn key methodologies, including quantitative and qualitative approaches. The diversity of authors and topics make the book widely applicable to a range of fields, and it will be of great interest to researchers, students, practitioners, and decision makers working towards the goals of net zero and decarbonisation.

A zero-suppressed decision diagram (ZDD) is a data structure to represent objects that typically contain many zeros. Applications include combinatorial problems, such as graphs, circuits, faults, and data mining. This book consists of four chapters on the applications of ZDDs. The first chapter by Alan Mishchenko introduces the ZDD. It compares ZDDs to BDDs, showing why a more compact representation is usually achieved in a ZDD. The focus is on sets of subsets and on sum-of-products (SOP) expressions. Methods to generate all the prime implicants (PIs), and to generate irredundant SOPs are shown. A list of papers on the applications of ZDDs is also presented. In the appendix, ZDD procedures in the CUDD package are described. The second chapter by Tsutomu Sasao shows methods to generate PIs and irredundant SOPs using a divide and conquer method. This chapter helps the reader to understand the methods presented in the first chapter. The third chapter by Shin-Ichi Minato introduces the "frontier-based" method that efficiently enumerates certain subsets of a graph. The final chapter by Shinobu Nagayama shows a method to match strings of characters. This is important in routers, for example, where one must match the address information of an internet packet to the proprer output port. It shows that ZDDs are more compact than BDDs in solving this important problem. Each chapter contains exercises, and the appendix contains their solutions.

Zero has been axial in human development, but the origin and discovery of zero has never been satisfactorily addressed by a comprehensive, systematic and above all interdisciplinary research program. In this volume, over 40 international scholars explore zero under four broad themes: history; religion, philosophy & linguistics; arts; and mathematics & the sciences. Some propose that the invention/discovery of zero may have been facilitated by the prior evolution of a sophisticated concept of Nothingness or Emptiness (as it is understood in non-European traditions); and conversely, inhibited by the absence of, or aversion to, such a concept of Nothingness in the West. But not all scholars agree. Join the debate.

A proven program for enhancing students' thinking and comprehension abilities Visible Thinking is a research-based approach to teaching thinking, begun at Harvard's Project Zero, that develops students' thinking dispositions, while at the same time deepening their understanding of the topics they study. Rather than a set of fixed lessons, Visible Thinking is a varied collection of practices, including thinking routines?small sets of questions or a short sequence of steps?as well as the documentation of student thinking. Using this process thinking becomes visible as the students' different viewpoints are expressed, documented, discussed and reflected upon. Helps direct student thinking and structure classroom discussion Can be applied with students at all grade levels and in all content areas Includes easy-to-implement classroom strategies The book also comes with a DVD of video clips featuring Visible Thinking in practice in different classrooms.

When the hammer and sickle came down in late 1991, Russia’s feverish new market opened for business. From banking to breweries, sectors emerged out of nowhere, in a country that had never had a functioning economy. For the next three turbulent decades, a wild, proto-capitalist free-for-all transformed Russian society. Then, in 2022, Putin launched the full-scale invasion of Ukraine. The market started to collapse; Western firms fled Moscow’s skyscrapers. No country this large had ever remade itself so dizzyingly – now, just as dramatically, it was over. The intervening decades had seen phenomenal successes and crushing failures; the creation and destruction of enormous fortunes. How did it all happen? Zero Sum brings to life the complex, vivid colour of one of the greatest experiments in the history of global commerce. What have businesses learnt—or failed to learn—from this adventure, both about Russia and about dynamics between countries and companies in the face of relentless change?

Seminar paper from the year 2018 in the subject English Language and Literature Studies - Linguistics, grade: 2,3, Christian-Albrechts-University of Kiel, language: English, abstract: Singapore is a country with a remarkable linguistic diversity. This is due to the heterogeneous population and numerous ethnic groups which inhabit it. Over the years, the different languages in Singapore, dominated by Chinese dialects like Mandarin, Hokkien or Cantonese, had to compete with another input variety as a result of permanent British settlement in 1819, namely British English. Nowadays, it is the language of government, business, law courts, science and also education. English is taught in school as the First Language, whereas the people’s mother tongue stands behind. Finally, a variety called "Singapore English" (SgE), which had a significant input from both, the prevalent Chinese variety Mandarin and British English, evolved and is constantly positioned between influences of these two. In contact varieties of English, like SgE is one, various features which distinguish the language emerged. Often, they are even pervasive or obligatory, although they do not occur in Standard English (StE). One of them is the zero-indefinite article where StE requires one. This seminar paper will investigate the usage of the zero-indefinite article in SgE. It is supposed to reveal how often speakers of SgE actually realize the indefinite article in a communication, either spoken or written, and if they do not make use of it, in which contexts the omission occurs. This aspect is of particular interest for the whole topic of World Englishes, because speakers of StE often tend to consider features of a variety as a mistake. But they are not only learner-errors, there is an underlying pattern and a reason for the occurrence of such features and this term paper aspires to provide an impulse in reference to approach the structure of indefinite article omission in SgE.
