And how can you predict future eclipses and occultations of stars by minor planets? The questions asked by serious amateur astronomers are answered in this authoritative and wide-ranging guide, first published in 1994. For each topic, sound practical methods of observation and the scientific background are given to lead you to better observations. Guidelines also show you how to record and catalogue your observations using the recognised professional terminology and classification schemes. From the simplest pencil drawings of the moon to observations of the most distant galaxies with state-of-the-art CCD cameras and photoelectric photometers, this guide is packed with practical tips for all types of amateur observations. It will develop the observational skills of the keen novice and satisfy the more demanding needs of the experienced amateur astronomer.

The relationship between the police and young people in Australia is a topic of growing concern in Australian society. While people are concerned about juvenile crime, worries have also been expressed about police harassment and violence directed at young people. This book, first published in 1994, provides a sustained analysis of police-youth relations, offering new insights into how young people are policed. Some specific areas addressed include: the legal framework of police-youth interaction in Australia; the rights of young people; the policing of Aboriginal youth; the relationship between the police and young women; and ethnic and community policing, and likely future directions in policy. Written by a team of the leading people in the field this book makes an important contribution to debate on a critical issue. The Police and Young People in Australia shows the implications that contemporary police methods and practices have on the exercise of basic legal rights in Australian s

In his new book, Professor Martin Robertson - author of A History of Greek Art (CUP 1975) and A Shorter History of Greek Art (CUP 1981) - draws together the results of a lifetime's study of Greek vase-painting, tracing the history of figure-drawing on Athenian pottery from the invention of the 'red-figure' technique in the later archaic period to the abandonment of figured vase-decoration two hundred years later. The book covers red-figure and also work produced over the same period in the same workshops in black-figure and other techniques, especially that of drawing in outline on a white ground. The book is intended as a companion volume to Sir John Beazley's The Development of Attic Black-figure (originally published in 1951 by California University Press), and as an examination and defence of Beazley's methods and achievements. This book is a major contribution to the history of Greek vase-painting and anyone seriously interested in the subject - whether scholar, student, curator,

In this book David Currie and Paul Levine address a broad range of issues concerning the design and conduct of macroeconomic policy in open economies. Adopting neo-Keynesian models for which monetary and fiscal policy have short-term real effects, they analyse active stabilisation policies in both a single- and multi-country context. Questions addressed include: the merits of simple policy rules, policy design in the face of uncertainty and international policy coordination. A central feature of the book is the treatment of credibility and the effect of a policy-maker's reputation for sticking to announced policies. These considerations are integrated with coordination issues to produce a unique synthesis. The volume develops optimal control methods and dynamic game theory to handle relationships between governments and a conscious rational private sector and produces a unified, coherent approach to the subject. This book will be of interest to students and teachers of open economy mac

Growth, Maturation and Body Composition documents one of the most remarkable and significant studies in the field of human biology. The Fels Longitudinal Study is the longest, largest and most productive serial study of human growth, maturation and body composition. This book shows how data collected from more than 1000 participants during the past 60 years have been analysed to test a wide range of hypotheses, and describes how the findings have led to the development of improved research methods. Topics covered include the management and analysis of data, prenatal, familial and genetic studies, physical growth, development and maturation, bones and teeth, body composition, and risk factors for cardiovascular disease. With more than 1000 specialized publications of Fels data, the present book provides a unique overview of this fascinating research programme, which will be of interest to a wide range of researchers, including those in the fields of physical anthropology, nutrition scie

This book, the first in the Cambridge Nonlinear Science Series, presents the fundamentals of chaos theory in conservative systems, providing a systematic study of the theory of transitional states of physical systems which lie between deterministic and chaotic behaviour. The authors' treatment of transitions to chaos, the theory of stochastic layers and webs, and the numerous applications of this theory, particularly to pattern symmetry, will make the book of importance to scientists from many disciplines.The authors have been meticulous in providing a detailed presentation of the material, enabling the reader to learn the necessary computational methods and to apply them in other problems. The inclusion of a significant amount of computer graphics is also an important aid to understanding. The final section of the book contains a fascinating collection of patterns in art and living nature. The book will be of interest to graduate students and researchers in physics and mathematics who

The authors describe here a framework in which the type notation of functional languages is extended to include a notation for binding times (that is run-time and compile-time) that distinguishes between them. Consequently the ability to specify code and verify program correctness can be improved. Two developments are needed, the first of which introduces the binding time distinction into the lambda calculus, in a manner analogous with the introduction of types into the untyped lambda calculus. Methods are also presented for introducing combinators for run-time. The second concerns the interpretation of the resulting language, which is known as the mixed lambda-calculus and combinatory logic. The notion of 'parametrized semantics' is used to describe code generation and abstract interpretation. The code generation is for a simple abstract machine designed for the purpose; it is close to the categorical abstract machine. The abstract interpretation focuses on a strictness analysis that

This book provides a complete and clear introduction to the use of adhesives to form load-bearing joints in bridges, civil engineering and building structures. Recent advances in adhesive technology have led to a rapid growth in the use of adhesives and in many cases, the use of adhesives can prove more convenient, less expensive, stronger, and more durable than traditional methods of joining. The first part of this book addresses the crucial factors involved in the formation of a successful adhesive joint, including adhesive selection, surface preparation, joint design, fabrication and protection from the environment. The second part of the book describes the growing uses of adhesives to repair and strengthen existing structures, in addition to describing their use in new constructions and applications which are now being developed for the future. The connections between the two parts of the book are brought out wherever possible so that the links between theory and practice are empha

The two volumes of John Wiens' Ecology of Bird Communities, first published in 1992, are recognised as having applications and importance beyond the study of birds to the wider study of ecology in general. The books contain a detailed synthesis of our understanding of the patterns of organisation of bird communities and of the factors that may determine them, drawing from studies from all over the world. The author, however, does more than simply review findings in bird community ecology. By emphasizing how proper logic and methods have or have not been followed and how different viewpoints have developed historically and have led to controversy, he extends the scope of these books far beyond the study of birds. Volume 1 Foundations and Patterns explores why avian community ecologists ask the questions they do and what philosophical and methodological approaches they have used to answer such questions. Most of the book is devoted to a critical evaluation of what is known about the natu

The two volumes of John Wiens' Ecology of Bird Communities have applications and importance to the whole field of ecology. The books contain a detailed synthesis of our current understanding of the patterns of organisation of bird communities and of the factors that may determine them, drawing from studies from all over the world. By emphasizing how proper logic and methods have or have not been followed and how different viewpoints have developed historically and have led to controversy, the scope of these books are extended far beyond the study of birds. Processes and Variations discusses the way in which bird community patterns have been interpreted. This second volume examines how the complexity and variability of natural environments may influence efforts to discern and understand the nature of these communities. Graduate students and professionals in avian biology and ecology will find these volumes a valuable stimulus and guide to future field studies and theory development.

The climbing habit in plants has apparently evolved numerous times. Species that climb are well represented in habitats ranging from tropical rain forests through temperate forests to semi-deserts. The Biology of Vines, first published in 1992, is a treatment of what is known about climbing plants, written by a group of experts and covering topics ranging from the biomechanics of twining to silvicultural methods for controlling vine infestations. Also included are detailed accounts of climbing plant evolution, stem anatomy and function, climbing mechanics, carbon and water relations, reproductive ecology, the role of vines in forest communities and their economic importance. The chapters are based on research on herbaceous vines and woody climbers (lianas) in both temperate and tropical zones, deserts and rain-forests and Old and New World areas. Much remains to be learned about the biology of these plants, but this volume provides a substantial foundation upon which further research c

The interacting boson-fermion model has become in recent years the standard model for the description of atomic nuclei with an odd number of protons and/or neutrons. This book describes the mathematical framework on which the interacting boson-fermion model is built and presents applications to a variety of situations encountered in nuclei. The book addresses both the analytical and the numerical aspects of the problem. The analytical aspect requires the introduction of rather complex group theoretic methods, including the use of graded (or super) Lie algebras. The first (and so far only) example of supersymmetry occurring in nature is also discussed. The book is the first comprehensive treatment of the subject and will appeal to both theoretical and experimental physicists. The large number of explicit formulas for level energies, electromagnetic transition rates and intensities of transfer reactions presented in the book provide a simple but detailed way to analyse experimental data.

The law was one of the most potent sources of authority and stability in early modern England. Historians, however, have argued over whether the discretion and flexibility embodied in the judicial system was used as a method of social control, and by focusing their attention on felonies and on the action of the protagonists in judicial decisions they have tended to ignore rich sources of information concerning attitudes towards and experiences of the law. Misdemeanour prosecutions affected many more people (and a broader social variety of participants) than felony prosecutions, and in their choice of methods of prosecution both victims and Justices of the Peace exercised considerably greater flexibility in responding to petty crimes than they did with felonies. This book examines the day-to-day operation of the criminal justice system in Middlesex from the point of view of plaintiffs and defendants, and offers an assessment of the social significance of the law in pre-industrial Englan

This book examines all major aspects of theatre practice and dramatic literature of the Victorian period. Michael Booth's comprehensive survey explores the social and cultural context of the theatre including theatre management, the audience, architecture and production methods, acting and the job of actor, as well as the drama itself. Within this framework, Booth discusses such topics as the effect on theatre of population growth and the spread of the railway system, the typical organization of a Victorian theatre company, the contribution to theatre of several important actor-managers, the use of stage machinery and lighting instruments, and the stock company and rehearsal system. The volume also includes a chapter on sources, numerous previously unpublished illustrations, and a chronology. The result is a lively and informative account of the diversity, energy, and colour of the Victorian stage. Theatre in the Victorian Age will be of interest to students and scholars of theatre his

Gravitational radiation has not been positively detected. Over the past two decades an army of extremely sensitive detectors has been built up, so that today its detection appears inevitable. In the opening chapters of this 1991 book David Blair introduces the concepts of gravitational waves within the context of general relativity. The sources of gravitational radiation for which there is direct observational evidence and those of a more speculative nature are described. He then gives a general introduction to the methods of detection. In the subsequent chapters he has drawn together the leading scientists in the field to give a comprehensive practical and theoretical account of the physics and technology of gravitational wave detection. David Blair has extensive knowledge of the subject and has visited most of the gravitational radiation experiments over the world. He has compiled a book which will be of lasting value to specialists, both the postgraduates and researchers in the fiel

The application of time series techniques in economics has become increasingly important, both for forecasting purposes and in the empirical analysis of time series in general. In this book, Terence Mills not only brings together recent research at the frontiers of the subject, but also analyses the areas of most importance to applied economics. It is an up-to-date text which extends the basic techniques of analysis to cover the development of methods that can be used to analyse a wide range of economic problems. The book analyses three basic areas of time series analysis: univariate models, multivariate models, and non-linear models. In each case the basic theory is outlined and then extended to cover recent developments. Particular emphasis is placed on applications of the theory to important areas of applied economics and on the computer software and programs needed to implement the techniques. This book clearly distinguishes itself from its competitors by emphasising the techniques

This book is intended as a self-contained introduction for non-specialists, or as a reference work for experts, to the particular area of approximation theory that is concerned with exact constants. The results apply mainly to extremal problems in approximation theory, which in turn are closely related to numerical analysis and optimization. The book encompasses a wide range of questions and problems: best approximation by polynomials and splines; linear approximation methods, such as spline-approximation; optimal reconstruction of functions and linear functionals. Many of the results are based on deep facts from analysis and function theory, such as duality theory and comparison theorems; these are presented in chapters 1 and 3. In keeping with the author's intention to make the book as self-contained as possible, chapter 2 contains an introduction to polynomial and spline approximation. Chapters 4 to 7 apply the theory to specific classes of functions. The last chapter deals with n-w

Physical Analysis for Tribology presents a unified approach to the study of wear in mechanical systems. Written by a leading expert who has studied and taught the subject both in Britain and the USA, this book will be valuable to researchers and students with a wide range of experience in tribology. The book concentrates on the methods of physical analysis and the applications of these techniques. This is then illustrated by a discussion of specific tribosystems. The early chapters provide an introduction to physical analysis that is thorough and rigorous. This prepares the reader with all the knowledge necessary to understand the subsequent discussion of applications. Although the description of systems is not exhaustive, the treatment and the theory are universal and will therefore be relevant to individual case studies. The book will appeal to tribologists from a wide variety of disciplines and will be of interest to researchers in physics, chemistry, metallurgy and mechanical engin

This book analyzes, with unprecedented breadth and coverage, the development, maturation, growth, and sudden decline of a distinctive, regional urban economic system that developed along the upper Mississippi River north of St. Louis during the middle third of the nineteenth century. Between 1820 and the Civil War the upper Mississippi River valley was at the center of national and international attention. At the edge of the northern frontier, this area, known as 'The Great West,' was the destination of hundreds of thousands of immigrants from the East and from northern Europe. To many, its rich lands, temperate climate, and vast rivers offered an opportunity to establish a better life, as well as a chance to enter, if desired, the mainstream of American life. Drawing from a variety of methods used in historical geography, economic history, systems analysis, and social and urban history, Timothy Mahoney analyzes how early settlement patterns were affected by experience, climate, and ge

This book is concerned with techniques for formal theorem-proving, with particular reference to Cambridge LCF (Logic for Computable Functions). Cambridge LCF is a computer program for reasoning about computation. It combines the methods of mathematical logic with domain theory, the basis of the denotational approach to specifying the meaning of program statements. Cambridge LCF is based on an earlier theorem-proving system, Edinburgh LCF, which introduced a design that gives the user flexibility to use and extend the system. A goal of this book is to explain the design, which has been adopted in several other systems. The book consists of two parts. Part I outlines the mathematical preliminaries, elementary logic and domain theory, and explains them at an intuitive level, giving reference to more advanced reading; Part II provides sufficient detail to serve as a reference manual for Cambridge LCF. It will also be a useful guide for implementors of other programs based on the LCF approa

This book deals with the methods of X-ray production at a level which is accessible to advanced undergraduates and researchers who use X-rays. It also discusses the fundamentals of these physical properties from an experimental viewpoint which is not covered in more specialised texts. The book begins with a survey of work carried out before 1945. Continuous and characteristic spectra are discussed followed by a description of techniques used in their study. Further studies of production, absorption and scattering in atomic and nuclear processes are described, including a completely new chapter on X-ray production by protons, alpha-particles and ions. The concluding chapter surveys some more advanced fields of study. It will be very valuable to all research and industrial physicists working with X-rays who need to know about their fundamental properties in more detail. In this second edition SI units are used throughout and the material reflects the changes in the use of X-rays and the

This book sets out a generative structuralist conception of general theoretical sociology; its philosophy, its problems, and its methods. The field is defined as a comprehensive research tradition with many intersecting subtraditions that share conceptual components. The focus is on formalization and unification as processes that can help advance the state of theory today. An integrative philosophy of the field is set out in terms of a process worldview, with a focus on generativity in explanation and a conception of the structure of theories as hierarchical meaning control systems. This philosophy is implemented in two phases. In the first phase, Professor Fararo defines the core problems of theoretical sociology in the context of setting out and illustrating the logic of a nonlinear dynamical social systems framework. A critical analysis of the outcome of this phase then leads, in the second phase, to formal treatments of action principles and structural analysis. A variety of tradit

This was the first paperback edition of a classic work of recent English historiography, first published in 1981. In analysing the population of a country over several centuries, the authors qualify, confirm or overturn traditional assumptions and marshal a mass of statistical material into a series of clear, lucid arguments about past patterns of demographic behaviour and their relationship to economic trends. The Population History of England presents basic demographic statistics - monthly totals of births, deaths and marriages - and uses them in conjunction with new methods of analysis to determine population size, gross production rates, expectation of life at birth, age structure and net migration totals. The results make it possible to construct a new model of the interplay of economic and demographic variables in England before and during the industrial picture of English population trends between 1541 and 1871 is a remarkable achievement and in a short preface, the authors cons

David Halliburton's book is a richly textured study of the complete writings of Stephen Crane, including Maggie: A Girl of the Streets, The Red Badge of Courage, and the less well-known fiction, newswriting, and poetry. Offering close readings of the works within a broad framework, Halliburton sets out to explore the imaginative world Crane created in his total œuvre of fiction, poetry and reportage. Comparative and interdisciplinary methods, combined with insights from historians such as Toynbee and Hofsteader, enable Halliburton to shed light on a number of issues. These include Crane's interest in musicality, the importance of his poetry and journalism to his other writings, the phenomenology of his social structures, his mastery of prosody, and the relation of his writings to the ideas of thinkers such as William James, Santayana, Weber and Sartre. This ambitious and comprehensive book sets a standard by which to measure all future interpretations of Crane.

Combining the methods of the modern philosopher with those of the historian of ideas, Knud Haakonssen presents an interpretation of the philosophy of law which Adam Smith developed out of - and partly in response to - David Hume's theory of justice. While acknowledging that the influences on Smith were many and various, Dr Haakonssen suggests that the decisive philosophical one was Hume's analysis of justice in A Treatise of Human Nature and the second Enquiry. He therefore begins with a thorough investigation of Hume, from which he goes on to show the philosophical originality of Smith's new form of natural jurisprudence. At the same time, he provides an over all reading of Smith's social and political thought, demonstrating clearly the exact links between the moral theory of The Theory of Moral Sentiments, the Lectures on Jurisprudence, and the sociohistorical theory of The Wealth of Nations. This is the first full analysis of Adam Smith's jurisprudence; it emphasizes its normative a

This pioneering book studies the function and status of the written word in Carolingian society in France and Germany in the eighth- and ninth-centuries. It demonstrates that literacy was by no means confined to a clerical élite, but was dispersed in lay society and used for government and administration, and for ordinary legal transactions among the peoples of the Frankish kingdom. While exploiting a huge range of primary material, Professor McKitterick does not confine herself to a functional analysis of the written word in Carolingian northern Europe but goes on to assess the consequences and implications of literacy for the Franks themselves and for the subsequent development of European society after 1000. Key topics discussed include law and the use of the written word, the conduct and record of legal transactions, the economic and social status of the book in Carolingian society, the methods evolved to organize and define written knowledge, and the whole question of lay literacy

First published in 1961 this monograph deals with the analysis of unsteady lift distributions of thin oscillating wings at transonic speeds. Such distributions are needed for the prediction of flutter, which tends to occur more frequently at speeds near that of sound than in any other speed regime. This book emphasises analytical methods that treat the linearised problem for simple wing planforms such as rectangular and delta wings. There is a thorough discussion of the limitations of the validity of linearised theory as well as the proper boundary conditions to be applied for the case of flows with shocks. Although the standard approach in engineering practice is to sense transonic flow calculations with the aid of direct numerical simulations on a high-speed computer, the treatment in this classic monograph is still of value in the physical insight it provides and in the reference 'exact' solutions it supplies for simplified cases that may serve as validation cases for complicated co

This 1989 book describes the physico-chemical principles of the high vacuum techniques used by chemists. It is a guide to the choice of suitable equipment, the methods of constructing the systems, and the ways of using them. Professor Plesch's book is the only up-to-date work on the type of high vacuum systems (HVS) used by chemists and it is the first ever to describe in detail the actual construction, manifold uses, method of operation, and final dismantling of an HVS. It includes descriptions of a very wide range of devices for making measurements (conductivity, spectra, kinetics, etc.) in vacuum. The author draws on over 40 years of his own experiences and those of others in many parts of the world, and many of the tricks and gadgets have not been published before. The book will be an essential companion on the bench of every chemist involved in the synthesis of, or measurements on, air-sensitive compounds.

This is the third edition of a successful textbook, now with material added to illustrate the potential of computers for biologists. It is a lucid introduction to the principles and more elementary techniques of statistical reasoning, particularly as they are relevant to the biologist. Special attention is paid to the validity and use of statistical procedures, the interpretation of results, and the meanings of the conclusions which can then be drawn. The understanding of statistical methods is aided by full explanations of how calculations are built up. A particular feature of this edition is the inclusion, of new material to demonstrate the potential usefulness of computers in biological statistical analysis and to this end computer analyses of a selection of the examples are presented, using several different statistical languages. The examples are designed to guide and encourage the biologist to pursue the use of these languages further. The book assumes no mathematical training an

The Ngwa region lies in the heart of the Nigerian palm belt. Palm oil is one of the oldest foodstuffs of the region and has also been an export crop, produced mainly by women, from the early nineteenth century to the present day. This 1988 book describes the rise and fall of the oil palm export industry. In contrast to the views of both dependency and vent-for-surplus theorists, it is shown that patterns of export growth and capital investment were heavily influenced by locally inspired changes in food production methods, gender and intergenerational relationships. The processes of change within the domestic and export economies became increasingly closely intertwined after 1924, when African coastal middlemen began to settle further inland and to spread the knowledge of cassava and Christianity. This book draws upon a wide range of economic, botanical, anthropological and historical studies as well as on colonial archives, but its heart lies in the oral evidence and life histories gen

'Why still read it? Why should scholars consult it and undergraduates study it? The plan answer is that still after ninety years remains the greatest single book on English medieval history': thus J. C. Holt in his foreword to this new impression of one of the classic historical texts in any language. In three extended essays Maitland exploits the information in Domesday to analyse and reconstruct the society, law, government, economy and even something of the mental and imaginative world of early medieval England. Essay I examines the nature of English society in 1066 and how, by 1086, this had changed. The second essay explores pre-Conquest England, stretching back through the Anglo-Saxon law codes and land-books to the English settlement, its social structure and administrative geography. Essay III uses an exhaustive discussion of the hide (that 'dreary old question') to look again at methods of assessment and measurement, and their relationship to the wealth and resources of Englan

This book provides a striking synthesis of the standard theory of connections in principal bundles and the Lie theory of Lie groupoids. The concept of Lie groupoid is a little-known formulation of the concept of principal bundle and corresponding to the Lie algebra of a Lie group is the concept of Lie algebroid: in principal bundle terms this is the Atiyah sequence. The author's viewpoint is that certain deep problems in connection theory are best addressed by groupoid and Lie algebroid methods. After preliminary chapters on topological groupoids, the author gives the first unified and detailed account of the theory of Lie groupoids and Lie algebroids. He then applies this theory to the cohomology of Lie algebroids, re-interpreting connection theory in cohomological terms, and giving criteria for the existence of (not necessarily Riemannian) connections with prescribed curvature form. This material, presented in the last two chapters, is work of the author published here for the first

The American Novel series provides students of American literature with introductory critical guides to the great works of American fiction by giving details of the novel's composition, publication history and contemporary reception. The group of essays, each specially commissioned from a leading scholar in the field, examines the interpretative methods and prominent ideas on the text. There are also helpful guides to further reading. Specifically designed for undergraduates, the series will be a powerful resource for anyone engaged in the critical analysis of major American novels. This collection of essays on Moby-Dick reconnects Melville's great work with concerns that are central to readers in critical studies. Richard Brodhead introduces the volume with a discussion of the book's unique place in the canon of American literature. He then recounts the novel's history from its mixed reception in the mid-nineteenth century to its prevalent status as a classic. The five essays that fol

This study examines the history of the sugar economy and the peculiar development of plantation society over a three hundred year period in Bahia, a major sugar plantation zone and an important terminus of the Atlantic slave trade. Drawing on little-used archival sources, plantations accounts, and notarial records, Professor Schwartz has examined through both quantitative and qualitative methods the various groups that made up plantation society. While he devotes much attention to masters and slaves, he views slavery ultimately as part of a larger structure of social and economic relations. The peculiarities of sugar-making and the nature of plantation labour are used throughout the book as keys to an understanding of roles and relationships in plantation society. A comparative perspective is also employed, so that studies of slavery elsewhere in the Americas inform the analysis, while at many points direct comparisons of the Bahian case with other plantation societies are also made.

Some of the most important questions of the social sciences in the twentieth century have been posed by scholars working at the intersections of social theory and history viewed on a grand scale. The core essays of this book focus on the careers and contributions of nine of these scholars: Marc Bloch, Karl Polanyi, S. N. Eisenstadt, Reinhard Bendix, Perry Anderson, E. P. Thompson, Charles Tilly, Immanuel Wallerstein, and Barrington Moore, Jr. The essays convey a vivid sense of the vision and values each of these major scholars brings (or bought) to his work and analyze and evaluate the research designs and methods each used in his most important works. The introduction and conclusion discuss the long-running tradition of historically grounded research in sociology, while the conclusion also provides a detailed discussion and comparison of three recurrent strategies for bringing historical evidence and theoretical ideas to bear upon one another. informative, thought-provoking, and unusu

Diophantine equations over number fields have formed one of the most important and fruitful areas of mathematics throughout civilisation. In recent years increasing interest has been aroused in the analogous area of equations over function fields. However, although considerable progress has been made by previous authors, none has attempted the central problem of providing methods for the actual solution of such equations. The latter is the purpose and achievement of this volume: algorithms are provided for the complete resolution of various families of equations, such as those of Thue, hyperelliptic and genus one type. The results are achieved by means of an original fundamental inequality, first announced by the author in 1982. Several specific examples are included as illustrations of the general method and as a testimony to its efficiency. Furthermore, bounds are obtained on the solutions which improve on those obtained previously by other means. Extending the equality to a differen

How can the drag coefficient of a car be reduced? What factors govern the variation in the shape of the Earth's magnetosphere? What is the basis of weather prediction? These are examples of problems that can only be tackled with a sound knowledge of the principles and methods of fluid dynamics. This important discipline has applications which range from the study of the large-scale properties of the galaxies to the design of high precision engineering components. This book introduces the subject of fluid dynamics from the first principles. The first eleven chapters cover all the basic ideas of fluid mechanics, explaining carefully the modelling and mathematics needed. The last six chapters illustrate applications of this material to linearised sound and water waves, to high speed flow of air, to non-linear water waves on channels, and to aerofoil theory. Over 350 diagrams have been used to illustrate key points. Exercises are included to help develop and reinforce the reader's understa

This book comprises five expository articles and two research papers on topics of current interest in set theory and the foundations of mathematics. Articles by Baumgartner and Devlin introduce the reader to proper forcing. This is a development by Saharon Shelah of Cohen's method which has led to solutions of problems that resisted attack by forcing methods as originally developed in the 1960s. The article by Guaspari is an introduction to descriptive set theory, a subject that has developed dramatically in the last few years. Articles by Kanamori and Stanley discuss one of the most difficult concepts in contemporary set theory, that of the morass, first created by Ronald Jensen in 1971 to solve the gap-two conjecture in model theory, assuming Gödel's axiom of constructibility. The papers by Prikry and Shelah complete the volume by giving the reader the flavour of contemporary research in set theory. This book will be of interest to graduate students and research workers in set theory

Philosophers are increasingly coming to recognize the importance of Freudian theory for the understanding of the mind. The picture Freud presents of the mind's growth and organization holds implications not just for such perennial questions as the relation of mind and body, the nature of memory and personal identity, the interplay of cognitive and affective processes in reasoning and acting, but also for the very way in which these questions are conceived and an interpretation of the mind is sought. This volume of essays, by some of today's leading philosophers, explores all these topics, as well as the methods, results and status of the theory itself, while two 'classical' discussions by Wittgenstein and Sartre are also included. A number of the contributions – those by Donald Davidson, W. D. Hart, Jim Hopkins, Adam Morton, David Pears and Richard Wollheim – have not been published before, and a very useful bibliography is provided. It is an anthology that will be vital to anyone inte
