Basic Structures of Reality

Low-dimensional semiconductor structures, often referred to as nanocrystals or quantum dots, exhibit fascinating behavior and have a multitude of potential applications, especially in the field of communications. This book examines in detail the optical properties of these structures, giving full coverage of theoretical and experimental results, and discusses their technological applications. The author begins by setting out the basic physics of electron states in crystals (adopting a 'cluster-to-crystal' approach), and goes on to discuss the growth of nanocrystals, absorption and emission of light by nanocrystals, optical nonlinearities, interface effects, and photonic crystals. He illustrates the physical principles with references to actual devices such as novel light-emitters and optical switches.

This graduate text introduces relativistic quantum theory, emphasising its important applications in condensed matter physics. Basic theory, including special relativity, angular momentum and particles of spin zero are first reprised. The text then goes on to discuss the Dirac equation, symmetries and operators, and free particles. Physical consequences of solutions including hole theory and Klein's paradox are considered. Several model problems are solved. Important applications of quantum theory to condensed matter physics then follow. Relevant theory for the one electron atom is explored. The theory is then developed to describe the quantum mechanics of many electron systems, including Hartree-Fock and density functional methods. Scattering theory, band structures, magneto-optical effects and superconductivity are among other significant topics discussed. Many exercises and an extensive reference list are included. This clear account of relativistic quantum theory will be valuable t

This textbook and reference introduces the basic concepts of the mechanical behavior of composite materials and laminated composite structures. Topics include micromechanics, macromechanics, and bend

This book describes the stochastic method for ocean wave analysis. This method provides a route to predicting the characteristics of random ocean waves - information vital for the design and safe operation of ships and ocean structures. Assuming a basic knowledge of probability theory, the book begins with a chapter describing the essential elements of wind-generated random seas from the stochastic point of view. The following three chapters introduce spectral analysis techniques, probabilistic predictions of wave amplitudes, wave height and periodicity. A further four chapters discuss sea severity, extreme sea state, the directional wave energy spreading in random seas and special wave events such as wave breaking and group phenomena. Finally the stochastic properties of non-Gaussian waves are presented. Useful appendices and an extensive reference list are included. Examples of practical applications of the theories presented can be found throughout the text. This book will be suitab

What Does This Mean? is a basic hermeneutics textbook for Christians, especially those of the Lutheran tradition. It discusses textual criticism, semantics, pragmatics, and application of biblical texts to postmodern contexts. The areas of language, thought, reality, and more are also covered.

This is a first-hand account of one of the most creative and exciting periods of discovery in the history of physics. From 1960 until 1990 theoreticians and experimentalists worked together to probe deeper and deeper into the basic structure of reality, moving closer and closer to an understanding of the ultimate building blocks from which everything in the Universe is made. Gerard 't Hooft was closely involved in many of the advances in the development of the subject. In this book he gives a personal account of the process by which physicists came to understand the structure of matter, and to speculate on possible directions in which the subject may evolve in the future. This fascinating personal account of the last thirty years in one of the most dramatic areas in twentieth century physics will be of interest to professional physicists and physics students, as well as the educated general reader with an interest in one of the most exciting scientific detective stories ever.

Symbolism is a primary characteristic of the mind, deployed and displayed in every aspect of our thought and culture. In this important and broad-ranging book, Israel Scheffler explores the various ways in which the mind functions symbolically. This involves considering not only the world of science and the arts, but also such activities as religious ritual and child's play. The book offers an integrated treatment of ambiguity and metaphor, analyses of play and ritual, and an extended discussion of the relations between scientific symbol systems and reality. What emerges is a picture of the basic symbol-forming character of the mind. In addition to philosophers of art and science, likely readers of this book will include students of linguistics, semiotics, anthropology, religion, and psychology.

This book addresses key topics in social theory such as the basic structures of social life, the character of human activity, and the nature of individuality. Drawing on the work of Wittgenstein, the author develops an account of social existence that argues that social practices are the fundamental phenomenon in social life. This approach offers insight into the social formation of individuals, surpassing and critiquing the existing practice theories of Bourdieu, Giddens, Lyotard and Oakeshott. In bringing Wittgenstein's work to bear on issues of social theory the book shows the relevance of his work to a body of thought to which it has never been applied. The book will be of particular interest to philosophers of the social sciences, a wide range of social theorists in political science and sociology, as well as some literary theorists.

This book gives a comprehensive description of the physics and applications of resonant tunnelling diodes. The opening chapters of the book set out the basic principles of coherent tunnelling theory. The effects of impurity scattering, femtosecond dynamics, non-equilibrium distribution and intrinsic bistabilities are then described in detail. The applications of RTDs, such as in high-frequency signal generation and multi-valued data storage, are also reviewed. The book closes with a chapter devoted to the more recent field of resonant tunnelling through laterally confined zero-dimensional structures. Covering all the key theoretical and experimental aspects of this stimulating area of research, the book will be of great value to graduate students of quantum transport physics and device engineering, as well as to researchers in both these fields.

African oral literature, like other forms of popular culture, is not merely folksy, domestic entertainment but a domain in which individuals in a variety of social roles are free to comment on power relations in society. It can also be a significant agent of change capable of directing, provoking, preventing, overturning and recasting social reality. This collection examines the way in which oral texts both reflect and affect contemporary social and political life in Africa. It addresses questions of power, gender, the dynamics of language use, the representation of social structures and the relation between culture and the state. The contributors are linguists, anthropologists, folklorists, ethnomusicologists and historians, who present fresh material and ideas to paint a lively picture of current real-life situations. The book is an important contribution to the study of African culture and literature, and to the anthropological study of oral literature in particular.

For many applications a randomized algorithm is either the simplest algorithm available, or the fastest, or both. This tutorial presents the basic concepts in the design and analysis of randomized algorithms. The first part of the book presents tools from probability theory and probabilistic analysis that are recurrent in algorithmic applications. Algorithmic examples are given to illustrate the use of each tool in a concrete setting. In the second part of the book, each of the seven chapters focuses on one important area of application of randomized algorithms: data structures; geometric algorithms; graph algorithms; number theory; enumeration; parallel algorithms; and on-line algorithms. A comprehensive and representative selection of the algorithms in these areas is also given. This book should prove invaluable as a reference for researchers and professional programmers, as well as for students.

This is a first course in propositional modal logic, suitable for mathematicians, computer scientists and philosophers. Emphasis is placed on semantic aspects, in the form of labelled transition structures, rather than on proof theory. The book covers all the basic material - propositional languages, semantics and correspondence results, proof systems and completeness results - as well as some topics not usually covered in a modal logic course. It is written from a mathematical standpoint. To help the reader, the material is covered in short chapters, each concentrating on one topic. These are arranged into five parts, each with a common theme. An important feature of the book is the many exercises and an extensive set of solutions is provided.

This is the second volume in a major new initiative in the study of local history, designed to equip students and amateur enthusiasts with a mastery of the basic techniques and concepts required to pursue the subject in depth. From Family History to Community History explores population movements, spatial divisions and social structures in town and countryside, and gives pointers as to the meaning of 'community'. Regional settings, the idea of 'place', and changes over time are also examined, with special attention being paid to the patterns and the processes of all forms of migration. These themes give rise to new research ideas in family and community history.

This book is concerned with the bifurcation theory, the study of the changes in the structures of the solution of ordinary differential equations as parameters of the model vary. The theory has developed rapidly over the past two decades. Chapters 1 and 2 of the book introduce two systematic methods of simplifying equations: centre manifold theory and normal form theory, by which the dimension of equations may be reduced and the forms changed so that they are as simple as possible. Chapters 3–5 of the book study in considerable detail the bifurcation of those one- or two-dimensional equations with one, two or several parameters. This book is aimed at mathematicians and graduate students interested in dynamical systems, ordinary differential equations and/or bifurcation theory. The basic knowledge required by this book is advanced calculus, functional analysis and qualitative theory of ordinary differential equations.

This book describes the various methods currently used to deposit highly ordered organic films, and the physical techniques employed in characterising their properties. Such films are the subject of a great deal of research, motivated by their potential application in micro-electronics. Beginning with a discussion of the necessary basic physics and chemistry, the book proceeds to a description of the main topics of current research in this field. The Langmuir–Blodgett technique, self-assembly, and methods of film deposition exploiting the ordered structure of mesophases are described in detail. Liquid crystals, films at the air/water interface and biomembranes are also discussed. The book is aimed at those graduate students and established research workers with an interest in the physics and chemistry of these fascinating structures.

Related to the earlier well-known ACT production system theory, this book's basic goal is to present evidence for the psychological reality of a production system model of mind. Distinguished from the

This is a new and greatly revised edition of Professor Chandrasekhar's classic book Liquid Crystals, first published in 1977. The subject of liquid crystals has grown into an exciting interdisciplinary research field with important practical applications. This book presents a systematic and self-contained treatment of the physics of the different types of thermotropic liquid crystals - the three classical types, nematic, cholesteric and smectic, and the newly discovered discotic type. Included is a description of the structures of these four main types and their polymorphic modifications, their thermodynamical, optical and mechanical properties and their behaviour under external fields. The basic principles underlying the major applications of liquid crystals in display technology and in thermography are also discussed. This book will be of great value to advanced students and researchers in condensed matter physics, chemical physics, materials science and technology with an interest i

In this book about metaphysics the author defends a realistic view of universals, characterizing the notion of universal by considering language and logic, the idea of possibility, hierarchies of universals, and causation. He argues that neither language nor logic is a reliable guide to the nature of reality and that basic universals are the fundamental type of universal and are central to causation. All assertions and predications about the natural world are ultimately founded on these basic universals. A distinction is drawn between unified particulars (which reveal natural principle of unity) and arbitrary particulars (which lack such a principle); unified particulars are the terms of causal relations and thus the real constituents of the world. The world is not made up of events but of unified particulars and basic universals.

This is the first general account of the mechanics behind pre-industrial technology. By combining the skills of an engineer and an archaeologist, it shows how mechanics can be used to create a better understanding of the function of artifacts and the achievements of early technology. The authors examine technology from the earliest stone tools of more than two million years ago to the erection of the statues of Easter Island which continued into the seventeenth century. Representative material cultures from most areas of the world have been selected for this study and the book shows how sophisticated many of their apparently simple techniques and artefacts actually were. After an introduction to basic mechanics the book examines the elements of machines: the various structures which can be made to bridge openings; the mechanics involved in fashioning stone tools; projectiles such as the spear and boomerang; the efficiency of transport by land and water; and the mechanics of musical ins

This book describes physical conditions in the upper atmosphere and magnetosphere of the Earth. The account is introductory, at a level suitable for readers with a basic inderstanding of physics and explains the principles of physical investigation. The principal material covers the neutral and ionized upper atmosphere, the magnetosphere, and structures, dynamics, disturbances and irregularities. This textbook is suitable for advanced undergraduates and new postgraduates who are taking introductory courses in upper atmospheric, ionospheric, or magnetospheric physics.

This is an updated and expanded second edition of a successful and well-reviewed text presenting a detailed exposition of the modern theory of supermanifolds, including a rigorous account of the super-analogs of all the basic structures of ordinary manifold theory. The exposition opens with the theory of analysis over supernumbers (Grassman variables), Berezin integration, supervector spaces and the superdeterminant. This basic material is then applied to the theory of supermanifolds, with an account of super-analogs of Lie derivatives, connections, metric, curvature, geodesics, Killing flows, conformal groups, etc. The book goes on to discuss the theory of super Lie groups, super Lie algebras, and invariant geometrical structures on coset spaces. Complete descriptions are given of all the simple super Lie groups. The book then turns to applications. Chapter 5 contains an account of the Peierals bracket for superclassical dynamical systems, super Hilbert spaces, path integration for fe

The fundamental task of philosophy since the seventeenth century has been to determine whether the essential principles of both knowledge and action can be discovered by human beings unaided by an external agency. No one philosopher contributed more to this enterprise than Kant, whose Critique of Pure Reason (1781) shook the very foundations of the intellectual world. Kant argued that the basic principles of the natural science are imposed on reality by human sensibility and understanding, and thus that human beings are also free to impose their own free and rational agency on the world. This 1992 volume is the only systematic and comprehensive account of the full range of Kant's writings available, and the first major overview of his work to be published in more than a dozen years. An internationally recognised team of Kant scholars explore Kant's conceptual revolution in epistemology, metaphysics, philosophy of science, moral and political philosophy, aesthetics, and the philosophy o

Social Change in Modern France is concerned with the radical transformations which have taken place within French society since the mid-twentieth century. The authors contended that these changes constitute a revolution in French affairs as important as that of 1789. From the late 1950s onwards, the traditional social structures of the Third Republic have been transformed: peasantry and bourgeoisie have disappeared or mutated; the great national institutions of church, army, trade unions and schools have declined or severely weakened, and a late and rapid industrialisation has wrought profound economic changes. Even the French Communist Party has become a virtual irrelevance. All these institutions, so characteristic of French society throughout the Third Republic, have now ceased to be the object of major conflicts and tensions. In their stead local institutions, voluntary associations and the family have acquired a renewed strength and serve as the basic network for social relations

This textbook is designed to aid the student in geological map interpretation. The book starts with basic concepts such as dip and strike, and progresses through a variety of exercises based on folds, faults and unconformities, up to and including the interpretation of Geological Survey Maps. In order to give a sense of reality to the text, frequent reference is made to actual examples on which many of the problem maps are based. Also included in the text are exercises concerned with bore-hole interpretation and correlation. The book, which is in two sections, is unique in that the second section contains worked solutions to the questions set in the first half.

Jazz Chant Fairy Tales is a collection of enchanting fairy tales. Set to rhythm, each fairy tale presents basic language structures and teaches conversational American English.

This book, which grew out of Steven Bleiler's lecture notes from a course given by Andrew Casson at the University of Texas, is designed to serve as an introduction to the applications of hyperbolic geometry to low dimensional topology. In particular it provides a concise exposition of the work of Neilsen and Thurston on the automorphisms of surfaces. The reader requires only an understanding of basic topology and linear algebra, while the early chapters on hyperbolic geometry and geometric structures on surfaces can profitably be read by anyone with a knowledge of standard Euclidean geometry desiring to learn more abour other 'geometric structures'.

The place of money capital in the theory of the firm has remained a relatively neglected question in traditions of economic analysis. In this highly integrative work, issues in production, pricing, capital investment and financial theory are brought to new levels of interdependence. Developing a three-part argument, Money Capital in the Theory of the Firm deals successively with the theoretical issues and analytic motivation, the neoclassical tradition and postclassical perspectives. In doing so, it presents a self-contained foundation in the basic structures of microeconomic analysis relating to optimize decision making in the firm and in the accounting concepts and statistical apparatus of probability theory relevant to the neoclassical aspects of the argument. Additionally, the book provides the essential mathematical development of such advanced topics as utility functions defined over stochastic arguments, the equilibrium theory of financial asset prices and yields, the cost of mo

In this landmark study, originally published in 1964, Peter Blau considers a basic question: How does social life become organized into increasingly complex structures of associations among humans? "B

Mathematical Physics is an introduction to such basic mathematical structures as groups, vector spaces, topological spaces, measure spaces, and Hilbert space. Geroch uses category theory to emphasize

Computing is an exact science and the systematic study of any aspect necessarily involves the use of mathematical models. Moreover, the rate at which the subject is evolving demands a facility for developing new mathematical systems to keep pace with new computing systems and this requires an appreciation of how mathematics works. An understanding of the underlying mathematical structure facilitates the construction of suitable computer programs to perform computations. Assuming no specific knowledge of mathematics, the authors describe all the basic concepts required and progress from sets (rather than numbers) through a variety of algebraic structures that permit the precise description, specification and subsequent analysis of many problems in computing. The material included provides the essential mathematical foundations for core topics of computer science and extends into the areas of language theory, abstract machine theory and computer geometry. Computer Mathematics will be of

The verbal statements of the actors and the researchers' own observations of their behaviour constitute two basic kinds of data which every anthropologist collects during his or her fieldwork. Yet the nature of social reality, and its availability to the observer, remains a fundamental methodological problem for the social anthropologist. In this book the authors argue that the difference between these two kinds of data is not merely a casual difference in the way in which the information comes to the anthropologist. Rather, it connotes the difference between the areas or domains of the social reality under study. One of these domains is formed by the notions or ideas people hold (i.e. their norms and their representations of the world and the existing state of affairs) and the other by the actions which they actually perform.

This Second Course continues the development of the theory and applications of stochastic processes as promised in the preface of A First Course. We emphasize a careful treatment of basic structures i

The second volume continues the course of study started in Volume 1, but may be used independently by those already possessing an elementary knowledge of the subject. A summary of basic group theory is followed by accounts of group homomorphisms, rings, fields and integral domains. The related concepts of an invariant subgroup and an ideal in a ring are brought in and the reader introduced to vector spaces and Boolean algebra. The theorems behind the abstract work and the reasons for their importance are discussed in greater detail than is usual at this level. The book is intended both for those who, educated in traditional mathematics, wish to know something about modern algebra and also for those already familiar with the elements of the subject who wish to study further. Fresh ideas and structures are introduced gradually and in a simpler manner, with concrete examples and much more informal discussion. There are many graded exercises, including some worked examples. This book is th

This text is a comprehensive introduction to research methods in social and cultural anthropology. The Peltos focus their discussion on the essential elements of preparing and analyzing the supporting evidence from which generalizations about human nature are derived. The specific elements of anthropological research - such as interviewing informants, observing ceremonial behaviour, and designing surveys - are all covered, but the primary aim is to show how basic observations can be systematically translated into socio-cultural generalizations. The authors place strong emphasis not only on quantification and statistics, but also on the more qualitative aspects of anthropological working styles that are essential to effective research. The two main themes of the book can be stated as follows: (1) anthropological generalizations and more complex theoretical structures can be built up only through careful implementation of basic concepts, the building blocks of all theory, and (2) success
