Defining and Measuring Nature (Second Edition)


Book Description

Measurement forms an essential part of our view of the world. Our world is measured and calibrated, and we are all subject to the tyranny of these numbers. In this updated and extended edition, Jeffrey Huw Williams outlines the history of measurement; particularly of the International System of units (SI). Since the previous edition, the base units of the SI have been redefined; realizing a 150-year-old dream for a measurement system based on unchanging, fundamental quantities of nature. This change has created a new SI, a Quantum SI, which will significantly change the way we look at nature in a quantitative manner, and greatly facilitate the advance of science. Key Features Significantly updated and extended new edition The first book to include the new Quantum SI base unit definitions Features wider societal and philosophical implications of a move away from physical standards Outlines the history of the science of measurement, and the origin of the Metric System More than a textbook of metrology, it is also a history of how we have arrived at the Quantum SI




Defining and Measuring Nature


Book Description

Weights and measures form an essential part of our ingrained view of the world. It is just about impossible to function effectively without some internalized system of measurement. In this volume, I outline a history of the science of measurement, and the

Assumptions about Human Nature


Book Description

"This book, which is in its second edition, provides a provocative mirror from which to discern more clearly one's own assumptions about human nature. . . . I found myself reflecting on the subject matter and its impact on my own life, including relationships, teaching, research, and therapy. . . . The author has done a superb job of raising our consciousness about human nature in this book, an I strongly recommend it to academic and applied psychologists. If you need an invitation to examine your views about human nature, this book is it." --C. R. Snyder, University of Kansas, Lawrence In general, are people trustworthy or unreliable, altruistic or selfish? Are they simple and easy to understand or complex and beyond comprehension? Our assumptions about human nature color everything from the way we bargain with a used-car dealer to our expectations about further conflict in the Middle East. Because our assumptions about human nature underlie our reactions to specific events, Wrightsman designed this second edition to enhance our understanding of human nature--the relationship of attitudes to behavior, the unidimensionality of attitudes, and the influence of social movements on beliefs. Psychologists, social workers, researchers, and students will find Assumptions About Human Nature an illuminating exploration into the philosophies of human nature.




Nature's Capacities and Their Measurement


Book Description

This book argues for the place of capacities within an grounds of meaning, not method. Yet it is questions of method that should concern the modern empiricist: can capacities be measured? Cartwright argues that they are measured if anything is. Stanford University's Gravity-Probe-B will measure capacities in a cryogenic dewar deep in space. More mundanely, we use probabilities to measure capacities, and the assumptions required to ensure that probabilities are a reliable instrument are investigated in the opening chapters of this book, where the early methods of econometrics set a model. The last chapter applies lessons about probabilities and capacities to quantum mechanics and the Bell inequalities. The central thesis throughout is that capacities not only can be admitted by empiricists, but indeed must be - otherwise the empirical methods of modern science will make no sense.




Ecological Understanding


Book Description

Ecology is an historical science in which theories can be as difficult to test as they are to devise. This volume, intended for ecologists and evolutionary biologists, reviews ecological theories, and how they are generated, evaluated, and categorized. Synthesizing a vast and sometimes labyrinthine literature, this book is a useful entry into the scientific philosophy of ecology and natural history. The need for integration of the contributions to theory made by different disciplines is a central theme of this book. The authors demonstrate that only through such integration will advances in ecological theory be possible. Ecologists, evolutionary biologists, and other serious students of natural history will want this book.




The Measurement of Appearance


Book Description

This second edition of a unique text/reference identifies the appearance attributes of objects and the methods available for measuring them, bringing together much material not previously organized for ready reference. The primary premise here is that ``object appearance'' involves not only color, but such attributes as gloss, luster, and translucency. The first part of the book, concerned with nature of appearance, draws from the fields of physiology and psychology and considers the eye-brain combination and the way it receives and interprets light signals. This is followed by a consideration of the optical properties of objects from the physical standpoint. The second part of the book deals with the numerical scales used to measure object appearance. The discussion here draws on psychophysics in describing the uses of physical techniques to give numbers having psychological significance. The third part of the book covers instruments for the measurement of the attributes of object appearance, their principles of design, and a survey of the major ones in use. The final chapter discusses specific applications of appearance measurement. Includes appendixes and a glossary.




Human Abilities


Book Description

This volume brings together many of the leading researchers on human intelligence and cognition to address issues including definition, measurement, and instructional design. Its publication is a result of the Inaugural Spearman Seminar recently held at the University of Plymouth -- a seminar that is slated to become a regularly scheduled event providing a major international forum for the presentation of work on human abilities. To properly inaugurate this series, scientific experts in this field were asked to reflect on various issues raised but not resolved in Charles Spearman's classic work, The Abilities of Man: Their Nature and Measurement, published in 1927. As a result of this approach, the book offers a unique overview of the way in which the study of human abilities has developed since 1927, and of current positions in the field. It offers exhaustive discussions on: * the nature of cognitive abilities and intelligence -- a review of how the factor analytic approach to abilities which grew out of Spearman's work has developed, thoughts regarding the contribution of a cross-cultural perspective, and an elucidation of some of the conceptual issues which often cloud discussions of ability; * different aspects of the contribution of cognitive psychology to our understanding of abilities -- the relationship between Spearman's g and working memory, links between attention and cognitive style, and the area of spatial abilities; * recent developments in latent variable and item response modeling; and * applied issues -- the argument that little predictive value can be gained in occupational selection from measuring abilities other than Spearman's g, and the question of aptitude treatment interactions in education.
