    Abstract: During the period September 1963 to December 1964. Georgetown University commemorated the 175th anniversary of its founding by presenting a series of special lectures in the various disciplines appropriate to a university. Among the subjects covered. in separate and coherent series. were the humanities. the arts. medicine. law. and religion. One of the series. entitled as a group. "Science and Society." is represented by this book. The ten papers presented here must be looked at in context: an effort was made to present to a largely lay audi­ ence a cross section of those aspects of recent advances in science and technology that were considered to haye the most striking or inclusive effects on man's view of his world. on desirable public policy. and on man's antici­ pations as to how further advances and applications of these advances were likely to change his environment. Clearly. so ambitious an undertaking could not be carried out within the compass of ten brief lectures. Within a general structure. it was necessary to use a sampling technique. The general plan was adopted of having three lectures representative of the philosophical sector. three of the public policy structure. and three which would partake of the nature of extrapolations into v vi INTRODUCTION the future. A tenth lecture was later added which could be considered to fit equally well into the second or third of these categories.

    Abstract: This volume explores in detail the four interrelated branches of the study of surface phenomena-surface thermodynamics, nucleation, diffusion, and fine-particles technology-providing an unusual and comprehensive body of knowledge that will be of interest and practical value to both materials researchers and practising engineers. The growing awareness-since the advent of the space age-among solid-state physicists, metallurgists, ceramists, chemical engineers, and mechanical engineers of the need for a broad interdisciplinary under­ standing of the fundamental phenomena common to all matedals has led in recent years to the development of a new field of scientific investigation, Materials Science. To help promote interest in and con­ tributions to this new technology, annual symposia on "Fundamental Phenomena in the Materials Sciences" have been organized by the Ilikon Corporation. The first symposium, reported in Volume 1 of this series, was held in Boston, Massachusetts, on February 1 and 2, 1963; sintering and plastic deformation were the main topics of discussion. The second meeting, also held in Boston, on January 27 and 28, 1964, was exclusively concerned with the general interdisciplinary problems related to surface phenomena, that is, all of those physical and chemical areas that are pertinent to the surface of a solid, or to the interface between a solid and a gas, a solid and a liquid, or a solid and a solid.

    Abstract: THE ECOLOGICAL SURVEY on which this book is based began to be planned in 1942, and since 1945 has been mainly centred upon Oxford University's estate at Wytham Woods, where a rich series of habitats from open ground and limestone to woodland with many springs and marshes interspersed occupies a hill set in riverine surroundings. Here biological research workers from the University have accumulated a considerable body of knowledge, some of which I have arranged in a general setting that allows one to comprehend some of the inter-related parts of the whole system. It is also intended to provide a framework for understanding animal communities elsewhere. The ecological inquirer is, more than most scien­ tific people, apt to fmd himself lost in a large labyrinth of interrelations and variables. The dictionary defmes a labyrinth as 'an intricate structure of inter­ communicating passages, through which it is difficult to fmd one's way without a clue'. This could equally be a figurative description of plant and animal communi­ ties. The present book seeks to provide a plan of construction of the labyrinth and a few new clues that may help the inquirer to know where he is on the gene­ ral ecological map. In presenting this blue-print of animal communities I have avoided giving long lists of species such as the botanist, with his smaller kingdom, can handle fairly well.

    Abstract: This symposium was a joint effort, co-sponsored by Northwestern University and Borg-Warner Corporation and included representatives of the latter-day estates of univerSity, industry, and government. All of these groups were deeply interested in participating, since the problems of man and his environment, especially his urban environ­ ment, are ones which can be solved only through a cooperative effort. The symposium proceedings present a review of the present position of man and his environment and outline the physical and social-science efforts being made to solve the problems posed by man's rapidly changing environment. The format of this book is such that Dr. Luther L. Terry's speech, "Environmental Health: Every­ body's Business," serves as an introduction to the many-faceted dis­ cussions on the interactions of man and his environment. Mr. P. B. Gordon's speech "Man and His Environment - Where Are We? Where Are We Going"?" aptly summarizes this symposium and serves this purpose in this publication. Every effort was exerted to make this symposium a general dis­ cussion meeting where contributions from both the formal speakers and the audience were received. The records of two panel discussions, including comments from the floor and replies by the speakers, are included in this volume. This publication is the result of the coordinated efforts of many contributors: the speakers, Northwestern University, Borg-Warner Corporation, the Symposium Planning Committee consisting of D. W.

    Abstract: This full-length translation of Professor Luria's book introduces to the English­ speaking world a major document in neuropsychology, summarizing Professor Luria's earlier contributions to that area for nearly a third of a century. It is a monumental contribution. Nothing of this scope exists in the Western literature of this field, with the possible exception of Ajuriaguerra and Hecaen's book (in French) on the cerebral cortex. Professor Luria's book thus marks a further and decisive step toward the eventual coalescence of neurology and psychology, a goal to which only a few laboratories in the East and West have been devoted over the last decades. The book is unique in its organization. The first half deals with observations and interpretations concerning the major syndromes of man's left cerebral hemisphere: those grievous distortions of higher functions traditionally described as aphasia, agnosia, and apraxia. There is also a detailed and brilliant analysis of the syndrome of massive frontal-lobe involvement. The entire second half of the book is given over to a painstaking description of Professor Luria's tests, many of them introduced by himself, and set out in such detail that anyone could repeat them and thus verify Professor Luria's interpretations.

    Abstract: We here attempt to give a complete but concise treatment of the theory of steady viscometric flows of simple (non-Newtonian) fluids and to use that theory to discuss the design and interpretation of ex­ periments. We are able to present the theory with less mathematical machinery than was used in our original papers, partly because this Tract has more limited aims than those papers, and partly because we employ a method, found by Noll and published here for the first time, for dealing with visco metric flows without the apparatus of rela­ tive Cauchy-Green tensors and reduced constitutive equations. To make the theory accessible to students not familiar with modern mathematics, we have added to our Tract an appendix explaining some of the mathe­ matical concepts essential to continuum physics.

    Abstract: This book is intended as an introduction to the application of physical theory to the study of semiconductors and transistor devices. The book is based on lecture courses given by the authors to second and third year honours students in the Electronics Department of Southampton University, England. Some elementary knowledge of physics, circuit theory, and vector methods is assumed. The book deals almost exc1u­ sively with the theoretical aspects, but references are given to experi­ mental work. The first two chapters discuss c1assical atomic theory and quantum mechanical applications to electron energy levels in atoms, in particular the hydrogen atom, and in one-dimensional crystalline solids leading to the distinctions between metals, insulators, and semiconductors. Chapter 3 deals with statistical mechanics in some detail, so that the reader can appreciate the historical background leading to the Fermi­ Dirac statistics for electrons in metals and semiconductors, and in chapter 4 these statistics are applied to determine the current carrier density in various types of semiconductor. Equations for drift and diffusion currents are obtained in chapter 5, and the results applied to uiliform and graded impurity semiconductors in chapter 6. Current flow across p-n junctions is analysed in chapter 7, and the p-n-p transistor theory is developed in chapter 8. The discussion is limited to p-n-p transistors, but similar results apply for the n-p-n transistor.

    Abstract: This work was begun quite some time ago at the University of Oxford during the tenure of an Overseas Scholarship of the Royal Commission for the Exhibition of 1851 and was completed at Banga­ lore when the author was being supported by a maintenance allowance from the CSIR Pool for unemployed scientists. It is hoped that significant developments taking place as late as the beginning of 1965 have been incorporated. The initial impetus and inspiration for the work came from Dr. K. Mendelssohn. To him and to Drs. R. W. Hill and N. E. Phillips, who went through the whole of the text, the author is obliged in more ways than one. For permission to use figures and other materials, grateful thanks are tendered to the concerned workers and institutions. The author is not so sanguine as to imagine that all technical and literary flaws have been weeded out. If others come across them, they may be charitably brought to the author's notice as proof that physics has become too vast to be comprehended by a single onlooker. E. S.

    Abstract: It is not so very long ago that up-to-date text-books on statistics were almost non-existent. In the last few decades this deficiency has largely been remedied, but in order to cope with a broad and rapidly expanding subject many of these books have been fairly big and expensive. The success of Methuen's existing series of monographs, in physics or in biology, for example, stresses the value of short inexpensive treatments to which a student can turn for an introduc­ tion to, or a revision of, specialised topics. In this new Methuen series the still-growing importance of prob­ ability theory in its applied aspects has been recognised by coupling together Probability and Statistics; and included in the series are some of the newer applications of probability theory to stochastic models in various fields, storage and service problems, 'Monte Carlo' techniques, etc. , as well as monographs on particular statistical topics. M. S. BARTLETT ix AUTHOR'S PREFACE The theory of stochastic processes has developed in the last three decades. Its field of application is constantly expanding and at present it is being applied in nearly every branch of science. So far several books have been written on the mathematical theory of stochastic processes. The nature of this book is different because it is primarily a collection of problems and their solutions, and is intended for readers who are already familiar with probability theory.

    Abstract: The aim of this book is to give an elementary treatment of multiple integrals. The notions of integrals extended over a curve, a plane region, a surface and a solid are introduced in tum, and methods for evaluating these integrals are presented in detail. Especial reference is made to the results required in Physics and other mathematical sciences, in which multiple integrals are an indispensable tool. A full theoretical discussion of this topic would involve deep problems of analysis and topology, which are outside the scope of this volume, and concessions had to be made in respect of completeness without, it is hoped, impairing precision and a reasonable standard of rigour. As in the author's Integral Calculus (in this series), the main existence theorems are first explained informally and then stated exactly, but not proved. Topological difficulties are circumvented by imposing some­ what stringent, though no unrealistic, restrictions on the regions of integration. Numerous examples are worked out in the text, and each chapter is followed by a set of exercises. My thanks are due to my colleague Dr. S. Swierczkowski, who read the manuscript and made valuable suggestions. w. LEDERMANN The University of Sussex, Brighton.

    Abstract: Until quite recently conditions in industry were often rough. Long hours were worked in insanitary and murky workshops, often with little regard to the effects upon the workpeople who were considered to be expendable. Now, however, these adverse conditions have been recognized and so remedied that there remains little in industrial conditions to disturb the public conscience. This does not mean that conditions of work in office or factory are perfect. The obvious and dramatic abuses of the human frame may have gone, but in their place have arisen stresses and strains which, taking effect only in the long term, are generally undramatic and often unrecognized. They exist none the less. No organized effort to study the effect of working conditions on man's performance was made until the end of World War I, when the Industrial Fatigue Research Board was set up. For the first time, men trained in the human sciences entered industry to study men at work. They made con­ tributions which set a new standard of scientific investigation into human performance and allowed executive action on the basis of evidence rather than of hunch. The Board's work differed from the contribution of Gilbreth in America in that the principles of Motion Study which he developed were, to a large extent, based on intelligent observation rather than controlled experiment. During the 1920S the National Institute of Industrial Psychology was founded and there was close collaboration between it and the I.F.R.B.

    Abstract: This book has its origin in a letter. In November of 1959, the late Prof. Dr. WERNER MEYER-EpPLER wrote to me, asking if I would contribute to a series he was planning on Communication. His book " Grundlagen und Anwendungen der Informationstheorie" was to serve as the initial volume of the series. After protracted consideration, I agreed to undertake the job provided it could be done outside my regular duties at the Bell Telephone Laboratories. Shortly afterwards, I received additional responsibilities in my research organization, and felt that I could not conveniently pursue the manuscript. Consequently, except for the preparation of a detailed outline, the writing was delayed for about a year and a half. In the interim, Professor MEYER-EpPLER suffered a fatal illness, and Professors H. WOLTER and W. D. KEIDEL assumed the editorial re­ sponsibilities for the book series. The main body of this material was therefore written as a leisurc­ time project in the years 1962 and 1963. The complete draft of the manuscript was duplicated and circulated to colleagues in three parts during 1963. Valuable comments and criticisms were obtained, revisions made, and the manuscript submitted to the publisher in March of 1964. The mechanics of printing have filled the remaining time. If the reader finds merit in the work, it will be owing in great measure to the people with whom I have had the good fortune to be associated.

    Abstract: Non-linear stability problems formulated in terms of non-linear partial differential equations have only recently begun to attract attention and it will probably take some time before our understanding of those problems reaches some degree of maturity. The passage from the more classical linear analysis to a non-linear analysis increases the mathematical complexity of the stability theory to a point where it may become discouraging, while some of the more usual mathematical methods lose their applicability. Although considerable progress has been made in recent years, notably in the field of fluid mechanics, much still remains to be done before a more permanent outline of the subject can be established. I have not tried to present in this monograph an account of what has been accomplished, since the rapidly changing features of the field make the periodical literature a more appropriate place for such a review. The aim of this book is to present one particular line of research, originally developed in a series of papers published in 'Journal de Mecanique' 1962-1963, in which I attempted to construct a mathematical theory for certain classes of non-linear stability problems, and to gain some understanding of the non-linear phenomena which are involved. The opportunity to collect the material in this volume has permitted a more coherent presentation, while various points of the analysis have been developed in greater detaiL I hope that a more unified form of the theory has thus been achieved.
