World In The Balance The Historic Quest For An Absolute System Of Measurement

The epic story of the invention of a global network of weights, scales, and instruments for measurement. Millions of transactions each day depend on a reliable network of weights and measures. This network has been called a greater invention than the steam engine, comparable only to the development of the printing press. Robert P. Crease traces the evolution of this international system from the use of flutes to measure distance in the dynasties of ancient China and figurines to weigh gold in West Africa to the creation of the French metric and British imperial systems. The former prevailed, with the United States one of three holdout nations. Into this captivating history Crease weaves stories of colorful individuals, including Thomas Jefferson, an advocate of the metric system, and American philosopher Charles S. Peirce, the first to tie the meter to the wavelength of light. Tracing the dynamic struggle for ultimate precision, World in the Balance demonstrates that measurement is both stranger and more integral to our lives than we ever suspected.

Systems of units still fail to attract the philosophical attention they deserve, but this could change with the current reform of the International System of Units (SI). Most of the SI base units will henceforth be based on certain laws of nature and a choice of fundamental constants whose values will be frozen. The theoretical, experimental and institutional work required to implement the reform highlights the entanglement of scientific, technological and social features in scientific enterprise, while it also invites a philosophical inquiry that promises to overcome the tensions that have long obstructed science studies.

Working at the nano-scale demands an understanding of the high-precision measurement techniques that make nanotechnology and advanced manufacturing possible. Richard Leach introduces these techniques to a broad audience of engineers and scientists involved in nanotechnology and manufacturing applications and research. He also provides a routemap and toolkit for metrologists engaging with the rigor of measurement and data analysis at the nano-scale. Starting from the fundamentals of precision measurement, the author progresses into different measurement and characterization techniques. The focus on nanometrology in engineering contexts makes this book an essential guide for the emerging nanomanufacturing / nanofabrication sector, where measurement and standardization requirements are paramount both in product specification and quality assurance. This book provides engineers and scientists with the methods and understanding needed to design and produce high-performance, long-lived products while ensuring that compliance and public health requirements are met. Updated to cover new and emerging technologies, and recent developments in standards and regulatory frameworks, this second edition includes many new sections, e.g. new technologies in scanning probe and e-beam microscopy, recent developments in interferometry and advances in co-ordinate metrology. Demystifies nanometrology for a wide audience of engineers, scientists, and students involved in nanotech and advanced manufacturing applications and research Introduces metrologists to the specific techniques and equipment involved in measuring at the nano-scale or to nano-scale uncertainty Fully updated to cover the latest technological developments, standards, and regulations

This book collects and organizes the original studies presented at PROMS 2015 conference on theories and applications of Rasch model. It provides useful examples of the Rasch model used to address practical measurement problems across a range of different disciplines including Item Response Theory (IRT), philosophy of measurement, dimensionality, the role of fit statistics and residuals, application, educational application, language testing, health-related research, business and industrial application and Rasch-based computer software. PROMS 2015 (Pacific Rim Objective Measurement Symposium) was held from August 20-24th 2015, in Fukuoka, Japan. The goal of this conference is to bring together the researchers from academia, universities, hospitals, industry, management sector as well as practitioners to share ideas, problems and solutions relating to the multifaceted aspects of Rasch Model.

International statistical comparisons of nations have become commonplace in the contemporary landscape of education policy and social science. This book discusses the emergence of these international comparisons as a particular style of reasoning about education, society and science. By examining how international educational assessments have come to dominate much of contemporary policymaking concerning school system performance, the authors provide concrete case studies highlighting the preeminent role of numbers in furthering neoliberal education reform. Demonstrating how numbers serve as ‘rationales’ to shape and fashion social issues, this text opens new avenues for thinking about institutional and epistemological factors that produce and shape educational policy, research and schooling in transnational contexts.

The chaos of the French Revolution was quickly followed by the somewhat less chaotic rule of Napoleon Bonaparte. For roughly 25 years, France saw five constitutions; countless warring political factions; governments that included a monarchy, a republic, and an empire; and almost constant warfare with most of Europe. At the same time, the French fought from within, sending thousands of its own people to the guillotine. And yet, there were perhaps more advancements during that time than any other in world history. Two brothers launched hot air balloons, inaugurating the age of flight, more than 100 years before Orville and Wilbur Wright. Modern chemistry was developed, eclipsing the strange and superstitious field of alchemy which proceeded it. The metric system was created. Napoleon Bonaparte's army explored Egypt for three years, and a French man would later translate the mysterious hieroglyphs. This book details these French advances and more, including the first photograph, the first automobile, and development of the process that spawned computer programming.

Is poetry still relevant today, or is it merely a dwindling historical art? How have poets of the recent past dealt with challenges to poetics? Seeking to chart the poetic act in a period not so much hostile as indifferent to poetry, Language at the Boundaries outlines spaces where poetry and poetics emerge in migration, translation, world literature, canon formation, and the history of science and technology. One can only come so close to fully possessing or explaining everything about the poetic act, and this book grapples with these limits by perusing, analyzing, deconstructing, and reconstructing creativity, implementing different approaches in doing so. Peter Carravetta consolidates historical epistemological positions that have accrued over the last several decades, some spurred by the modernism/postmodernism debate, and unpacks their differences--juxtaposing Vico with Heidegger and applying the approaches of translation studies, decolonization, indigeneity, committed literature, and critical race theory, among others. What emerges is a defense and theory of poetics in the contemporary world, engaging the topic in a dialectic mode and seeking grounds of agreement.

The Data Quality Assessment Framework shows you how to measure and monitor data quality, ensuring quality over time. You’ll start with general concepts of measurement and work your way through a detailed framework of more than three dozen measurement types related to five objective dimensions of quality: completeness, timeliness, consistency, validity, and integrity. Ongoing measurement, rather than one time activities will help your organization reach a new level of data quality. This plain-language approach to measuring data can be understood by both business and IT and provides practical guidance on how to apply the DQAF within any organization enabling you to prioritize measurements and effectively report on results. Strategies for using data measurement to govern and improve the quality of data and guidelines for applying the framework within a data asset are included. You’ll come away able to prioritize which measurement types to implement, knowing where to place them in a data flow and how frequently to measure. Common conceptual models for defining and storing of data quality results for purposes of trend analysis are also included as well as generic business requirements for ongoing measuring and monitoring including calculations and comparisons that make the measurements meaningful and help understand trends and detect anomalies. Demonstrates how to leverage a technology independent data quality measurement framework for your specific business priorities and data quality challenges Enables discussions between business and IT with a non-technical vocabulary for data quality measurement Describes how to measure data quality on an ongoing basis with generic measurement types that can be applied to any situation
