The book is written by international experts from the top nano-research groups that specialize in nanomaterials characterization. The book will appeal to nanomaterials researchers, and to SEM development specialists.

This handbook is a both a description of the current practice at the National Institute of Standards and Technology, and a compilation of the theory and lore of gauge block calibration. Most of the chapters are nearly self-contained so that the interested reader can, for example, get information on the cleaning and handling of gauge blocks without having to read the chapters on measurement schemes or process control, etc. This partitioning of the material has led to some unavoidable repetition of material between chapters. The basic structure of the handbook is from the theoretical to the practical. Chapter 1: basic concepts and definitions of length and units; Chapter 2: history of gauge blocks, appropriate definitions and a discussion of pertinent national and international standards; Chapter 3: physical characteristics of gauge blocks, including thermal, mechanical and optical properties; Chapter 4: a description of statistical process control (SPC) and measurement assurance (MA) concepts; and Chapters 5 and 6: details of the mechanical comparisons and interferometric techniques used for gauge block calibrations. Full discussions of the related uncertainties and corrections are included. Finally, the appendices cover in more detail some important topics in metrology and gauge block calibration.

This NIST IR of Selected Publications has been updated from the 2006 version and includes Good Laboratory Practices, Good Measurement Practices, and Standard Operating Procedures for volumetric calibrations.

Real science is dead. Researchers are no longer trying to seek and speak the truth. Scientists no longer believe in the truth. They no longer believe that there is an eternal unchanging reality beyond our human organisation which they have a duty to discover and disseminate. Hence, the vast structures of personnel and resources that constitute modern science are not real science but merely a professional research bureaucracy. The consequences? Research literature must be assumed to be worthless or misleading and should almost always be ignored. In practice, this means that nearly all science needs to be demolished (or allowed to collapse) and real science rebuilt outside the professional research structure, from the ground up, by real scientists who regard truth-seeking as an imperative and truthfulness as an iron law.

The National Institute of Standards and Technology Handbook 133, Checking the Net Contents of Packaged Goods, has been prepared as a procedural guide for the compliance testing of net contents statements on packaged goods. Compliance testing of packaged goods is the determination of the conformance results of the packaging, distribution, and retailing process (the packages) to specific legal requirements for net content declarations. This handbook has been developed primarily for the use of government officials; however it should also be useful to commercial and industrial establishments in the areas of packaging, distribution, and sale of commodities. In conducting compliance testing, the conversion of quantity values from one measurement system to another (e.g., from the metric system to the avoirdupois system) should be handled with careful regard to the implied correspondence between accuracy of the data and the number of digits displayed. In all conversion, the number of significant digits retained should ensure that accuracy is neither sacrificed nor exaggerated. For this edition of Handbook 133 all dimensions for test procedures, devices, or environments have been rounded to two significant digits (e.g., 2.5 cm to 1.0 in) or to a precision level applicable to the test equipment (e.g., 200 kPa for 25 psi and 35 MPa for 5000 psi).

Das Buch enthalt die Beitrage zu einem interdisziplinaren Symposium zur oekonomischen Analyse des Zivilrechts, das die Herausgeber mit Unterstutzung der Stiftung Volkswagenwerk im Marz 1988 veranstaltet haben und an dem in diesem Forschungsbereich ausgewiesene OEkonomen und Juristen aus dem In- und Ausland teilgenommen haben. Die Beitrage befassen sich - jeweils aus juristischer und aus oekonomischer Sicht - mit Grundsatzfragen der oekonomischen Analyse des Zivilrechts sowie mit konkreten Problemen des Deliktrechts, des Vertragsrechts und des Sachenrechts; hier wird im einzelnen die Leistungsfahigkeit der oekonomischen Analyse fur Rechtsanwendung und Rechtsfortbildung untersucht. Ausserdem wird in dem Buch der Frage nachgegangen, inwieweit das Prinzip der Allokationseffizienz mit anderen Rechtsprinzipien kollidiert und durch diese begrenzt wird.

The scienti c method is based on the measurement of di erent physical qu- tities and the search for relations between their values. All measured values of physical quantities are, however, a ected by uncertainty. Understanding the origin of uncertainty, evaluating its extent, and suitably taking it into account in data analysis, are fundamental steps for assessing the global accuracy of physical laws and the degree of reliability of their technological applications. The introduction to uncertainty evaluation and data analysis procedures is generally made in laboratory courses for freshmen. During my long-lasting teaching experience, I had the feeling of some sort of gap between the ava- able tutorial textbooks, and the specialized monographs. The present work aims at lling this gap, and has been tested and modi ed through a feedback interaction with my students for several years. I have tried to maintain as much as possible a tutorial approach, that, starting from a phenomenolo- cal introduction, progressively leads to an accurate de nition of uncertainty and to some of the most common procedures of data analysis, facilitating the access to advanced monographs. This book is mainly addressed to - dergraduate students, but can be a useful reference for researchers and for secondary school teachers. The book is divided into three parts and a series of appendices. Part I is devoted to a phenomenological introduction to measurement and uncertainty. In Chap.

An essential resource for scholars and a treat for curious readers, this uniquely detailed history of American weights and measures traces these everyday standards back to their originals and explains the ancient trade system on which they are based.

Derived from a course in fluid mechanics, this text for advanced undergraduates and beginning graduate students employs symmetry arguments to demonstrate the principles of dimensional analysis. The examples provided illustrate the effectiveness of symmetry arguments in obtaining the mathematical form of the functions yielded by dimensional analysis. Students will find these methods applicable to a wide field of interests.
After discussing several examples of method, the text examines pipe flow, material properties, gasdynamical examples, body in nonuniform flow, and turbulent flow. Additional topics include waves on a free liquid surface, examples with other fluid properties, and ideal gas equations of state. Figures appear throughout the text, which concludes with a bibliography.

Is there a universal set of rules for discovering and testing scientific hypotheses? Since the birth of modern science, philosophers, scientists, and other thinkers have wrestled with this fundamental question of scientific practice. Efforts to devise rigorous methods for obtaining scientific knowledge include the twenty-one rules Descartes proposed in his "Rules for the Direction of the Mind" and the four rules of reasoning that begin the third book of Newton's "Principia," and continue today in debates over the very possibility of such rules. Bringing together key primary sources spanning almost four centuries, "Science Rules" introduces readers to scientific methods that have played a prominent role in the history of scientific practice.

Editor Peter Achinstein includes works by scientists and philosophers of science to offer a new perspective on the nature of scientific reasoning. For each of the methods discussed, he presents the original formulation of the method; selections written by a proponent of the method together with an application to a particular scientific example; and a critical analysis of the method that draws on historical and contemporary sources.

The methods included in this volume are Cartesian rationalism with an application to Descartes' laws of motion; Newton's inductivism and the law of gravity; two versions of hypothetico-deductivism--those of William Whewell and Karl Popper--and the nineteenth-century wave theory of light; Paul Feyerabend's principle of proliferation and Thomas Kuhn's views on scientific values, both of which deny that there are universal rules of method, with an application to Galileo's tower argument. Included also is a famous nineteenth-century debate about scientific reasoning between the hypothetico-deductivist William Whewell and the inductivist John Stuart Mill; and an account of the realism-antirealism dispute about unobservables in science, with a consideration of Perrin's argument for the existence of molecules in the early twentieth century.

In June 1792, amidst the chaos of the French Revolution, two intrepid astronomers set out in opposite directions on an extraordinary journey. Starting in Paris, Jean-Baptiste-Joseph Delambre would make his way north to Dunkirk, while Pierre-François-André Méchain voyaged south to Barcelona. Their mission was to measure the world, and their findings would help define the meter as one ten-millionth of the distance between the pole and the equator -- a standard that would be used "for all people, for all time."

The Measure of All Things is the astonishing tale of one of history's greatest scientific adventures. Yet behind the public triumph of the metric system lies a secret error, one that is perpetuated in every subsequent definition of the meter. As acclaimed historian and novelist Ken Alder discovered through his research, there were only two people on the planet who knew the full extent of this error: Delambre and Méchain themselves.

By turns a science history, detective tale, and human drama, The Measure of All Things describes a quest that succeeded as it failed -- and continues to enlighten and inspire to this day.

In 1903 John Burroughs published an Atlantic Monthly article attacking popular nature writers--among them William J. Long and Jack London--as "sham naturalists."

The spirited "nature fakers" controversy that ensued reveals much about public attitudes toward nature at the time. Burroughs's argument that the writers invented facts and reported them as the gospel truth prompted a public literary debate, fueled by the avid participation of the nation's leading magazines and newspapers, and President Theodore Roosevelt's own denunciation of the 'faker' contingent. At issue was the conflict between science and sentiment as methods of understanding the creatures of the wild.

Ultimately, as Ralph Lutts demonstrates in "The Nature Fakers, " the dialogue resulted in a new standard of accuracy for the responsible nature writer and reflected a new way of thinking about moral responsibilities to wildlife.

This book is an introduction to concepts needed in the different parts of the process of doing science. It includes topics that will help achieve clarity in the posing of scientific questions, the design of ways to answer the questions, and the methods to evaluate the results and effectively communicate scientific information. It will be useful to the professional or student in the practice of writing papers, books or journal articles and can be applied to almost any area of science that requires presentation of data in an effective and informative way.

A blue whale is big; its the biggest animal alive. But it isn't the biggest thing there is. In this informative and engaging book, readers discover some big things, some bigger things, and the thing beyond measure--what can truly be called the Biggest Thing There Is!

The measurement practice section illustrates the application of objective measurement methods to personality psychology, a sociological study of school environment, personnel management, pain research, motor performance, and curriculum development. It emphasizes practice over theory, showing how measurement practice contributes valuable perspectives on substantive theory. The measurement theory section describes the development of new measurement models that extend objective measurement into learning contexts, rank-ordered data, and multidimensional profiles composed of subtests. These are complemented by a study of the use of objective measurement to examine the construct validity of items, and an exploration of the impact of text anxiety and item order on measurements. The final section examines recent developments in mathematical programming techniques applied to test assembly, parameter estimation and generalizability theory.

Messtechnik und Qualitatssicherung sind zwei Gebiete, die in der modernen arbeits- teiligen und spezialisierten Produktion immer enger zusammenwachsen. Es sind zwei Gebiete, die in Forschung, Entwicklung, Produktion und Anwendung gesetzmassig zu- nehmend Gewicht erhalten. Die Messtechnik liefert die Messinformationen zur Analyse, Beurteilung und Steuerung kontinuierlicher und diskontinuierlicher technischer Prozesse. Sie ist unerlasslich fur die Produktions- und Qualitatssteuerung sowie die Produktionsorganisation Und Produk- tionssicherheit. Daruber hinaus wird die Messtechnik zunehmend in Landwirtschaft, Medizin und Verkehrswesen angewendet sowie in technische Konsumguter integriert. Die Qualitatssicherung umfasst die Gesamtheit aller Massnahmen, die von der Pla- nung bis zum Absatz von Erzeugnissen durchgehend aufeinander abgestimmt sind, um die volkswirtschaftlich effektivste Qualitat sowohl der Erzeugnisse als auch der Produk- tion zu gewahrleisten. Im Buch ist beabsichtigt, das Lehrgebaude der Messtechnik und Qualitatssicherung in seinen Konturen zu umreissen und dabei disziplinare und interdisziplinare Gesetz- massigkeiten aufzuzeigen. Ausserdem wird angestrebt, Zusammenhange zwischen volks- wirtschaftlichen AufgabensteIlungen und daraus resultierenden Anforderungen an die Messtechnik und Qualitatssicherung deutlich zu machen. Das Buch stellt einen Versuch dar, das Gerust der Messtechnik und Qualitatssicherung mit knappen Worten in UEbersichten darzustellen. Um seinen Umfang in Grenzen zu halten und die UEbersichtlichkeit nicht in Frage zu stellen, waren Kompromisseerforder- lich. Besonders deutlich kommt das in zwei Punkten zum Ausdruck. Erstens musste bei der Theorie der Messtechnik und Qualitatssicherung zur weiteren Erklarung von Einzelheiten vielfach auf SpeziaIIiteratur verwiesen werden, die sehr um- fangreich ist.
