Book Synopsis World in the Balance: The Historic Quest for an Absolute System of Measurement by : Robert P. Crease

Download or read book World in the Balance: The Historic Quest for an Absolute System of Measurement written by Robert P. Crease. This book was released on 2011-10-24. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis The Reform of the International System of Units (SI) by : Nadine de Courtenay

Download or read book The Reform of the International System of Units (SI) written by Nadine de Courtenay. This book was released on 2019-01-15. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Fundamental Principles of Engineering Nanometrology by : Richard Leach

Download or read book Fundamental Principles of Engineering Nanometrology written by Richard Leach. This book was released on 2014-05-17. Available in PDF, EPUB and Kindle. Book excerpt: 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

Book Synopsis Pacific Rim Objective Measurement Symposium (PROMS) 2015 Conference Proceedings by : Quan Zhang

Download or read book Pacific Rim Objective Measurement Symposium (PROMS) 2015 Conference Proceedings written by Quan Zhang. This book was released on 2016-08-06. Available in PDF, EPUB and Kindle. Book excerpt: 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.
