Is death the end? Will there really be an afterlife? Does the Christian teaching about Heaven actually bring anyone real peace? Having been plagued by such questions, the author set out to find answers. This book is the result of one man's struggle with the certainty of the grave. In the first half, the scriptures are applied in an attempt to develop a Christian view of demise. However, section two draws on the best evidence from philosophy, science, history and personal experience that death is not the end. Throughout the book various types of death are examined and each one is likened to a doorway. If death is a doorway, everyone has their own idea of what it will look like. All of this enables the reader to construct a healthy view of death's door so that they may one day pass gracefully. Whether you are wrestling with the death of a loved one, facing the end of your own life, or live in fear of the grave, Death is a Doorway was written for you.

Domain theory is a subject that emerged as a response to natural concerns in the semantics of computation, and it involves the study of ordered sets that possess an unusual amount of mathematical structure. Disorder in Domain Theory explores the connection between domain theory and quantum information science and the concept that relates them: disorder.

Today, air-to-surface vessel (ASV) radars, or more generally airborne maritime surveillance radars, are installed on maritime reconnaissance aircraft for long-range detection, tracking and classification of surface ships (ASuW-anti-surface warfare) and for hunting submarines (ASW-anti-submarine warfare). Such radars were first developed in the UK during WWII as part of the response to the threat to shipping from German U-boats. This book describes the ASV radars developed in the UK and used by RAF Coastal Command during WWII for long-range maritime surveillance.

Containing an extensive illustration of the use of finite difference method in solving boundary value problem numerically, a wide class of differential equations have been numerically solved in this book.

Who knew that gecko feet inspired scientists to develop a stickier adhesive or that cockleburs in dog fur led to the invention of Velcro? Discovery Engineering uses these and other surprising cases of innovations sparked by accidental observations to teach about the amazing role of serendipity in science. The case studies in this new resource are a lively way to integrate engineering into your physical science classes. Middle and high school students will learn to understand fundamental science processes while trying out their own ideas for unexpected applications. Each of the book's 22 investigations starts with a real case of accidental inspiration that students explore through primary documents or historical accounts. Then it's time for the students to become the innovators. They're tasked to do research, examine data and physical materials, and use their own creativity to design new products or problem-solving applications. The investigations are easy to implement and flexible enough to use in part or as a whole. Students will learn one or more science concepts as they're exposed to background on the unpredictable nature of science. And they'll be intrigued by investigations with titles such as "By the Teeth of Your Skin: Shark Skin and Bacteria" and "The Slinky: From Ship to Staircase." Try this book and see what happens! The result may be more engaged students-and more great ideas about how gecko feet can inspire solutions to everyday problems.

This book presents simple interdisciplinary stochastic models meant as a gentle introduction to the field of non-equilibrium statistical physics. It focuses on the analysis of two-state models with cooperative effects and explores a variety of mathematical techniques to solve the master equations that govern these models. The models discussed are at the confluence of nanophysics, biology, mathematics and the social science, and they provide a pedagogical path toward understanding the complex dynamics of particle self-assembly with the tools of statistical physics.

PREFACE The present volume is the successor to and, in effect, a revision of the Ingersoll and Zobel text of some years ago. To quote from the earlier preface: . . . the theory of heat con duction is of importance, not only intrinsically' but also because its broad bearing and the generality of its methods of analysis make it one of the best introductions to more advanced mathe matical physics. The aim of the authors has been twofold. They have attempted, in the first place, to develop the subject with special reference to the needs of the student who has neither time nor mathematical preparation to pursue the study at great length. To this end, fewer types of problemsare handled than in the larger treatises, and less stress has been placed on purely mathe matical derivations such as uniqueness, existence, and con vergence theorems. The second aim has been to point out . . . the many applications of which the results are susceptible .... It is hoped that in this respect the subject matter may be of interest to the engineer, for the authors have attempted to select appli cations with special reference to their technical importance, and in furtherance of this idea have sought and received suggestions from engineers in many lines of work. While many of these applications have doubtless only a small practical bearing and serve chiefly to illustrate the theory, . . . the results in some cases . . . may be found worthy of note. The same may be said of the geological problems. While a number of solutions are here presented for the first time ... no originality can be claimed for the underlying mathematical theory which dates back, of course, to the time of Fourier. Since the above was written there has been a steady increase vi PREFACE in interest in the theory of heat conduction, largely along prac tical lines. The geologist and geographer are interested in a new tool which will help them in explaining many thermal phenomena and in establishing certain time scales. The engi neer, whose use of the theory was formerly limited almost entirely to the steady state, has developed many useful tables and curves for the solution of more general cases and is interested in finding still other methods of attack. The physicist and mathematician have done their part in treating problems which have hitherto resisted solution. The present volume carries out and extendsthe aims of the earlier one. Most of the old material has been retained, although revised, and almost an equal amount of new has been added. The geologist, geographer, and engineer will find many new applications discussed, while the mathematician, physicist, and chemist will welcome the addition of a little Bessel function and conjugate function theory, as well as the several extended tables in the appendixes. Some of these are new and have had to be specially evaluated. The number of refer ences has also been greatly enlarged and three-quarters of them are of more

Lissajous figures are produced by combining two oscillations at right angles to each other. The figures, drawn by mechanical devices called harmonographs, have scientific uses, but are also enjoyed for their own beauty. The author has been working with harmonographs since his undergraduate days, building several of them, lecturing on them and has written articles about them. This book is intended for people who enjoy physics or art or both.

VISION ITS DEVELOPMENT IN INFANT AND CHILD BY ARNOLD GESELL, M. D. FRANCES L. ILG, M. D. GLENNA E. BULLIS Assisted by VIVIENNE ILG, O. D. and G. N. GETMAN, O. D. PAUL B. HOEBER, INC. MEDICAL BOOK DEPARTMENT OF HARPER i-BROTHERS PREFACE The background, scope, and genesis of the present volume are out lined in an introductory chapter which follows. There is not much more which needs to be said by way of preface. The investigations of the Yale Clinic of Child Development since its founding in 1911 have been mainly concerned with the growth aspects of early human behavior. All told, the behavior characteristics of 34 age levels have been charted, encompassing the first ten years of life. An intensive longitudinal study of a group of five infants in 1927 estab lished methods for a systematic normative survey. These methods in cluded developmental examinations and inventories at lunar month intervals during the first year of life. Concurrent cinema records were analyzed to define significant behavior patterns and growth trends. Special attention was given to the ontogenetic patterning of posture, locomotion, prehension, and manipulation. Cinemanalysis, both of normative and experimental data, demon strated that the eyes play an important role in the ontogenesis of the total action system of the total child. The nature and the dynamics of that role constitute the subject matter of the present study. The adult human eye has been likened to a camera. This analogy has had some truth and much tradition in its favor. But it has tended to obscure the developmental factors which determine the structure and the organization of the visual functions during infancy and child hood. The development ofvision in the individual child is an extremely v PREFACE complex and protracted process for the very good reason that it took countless ages of evolution to bring human vision to its present pre eminence. Our culture is becoming increasingly eye minded with the advancing perfection and implementation of the organ of sight. What is that organ It is more than a dioptric lens and a retinal film. It embraces enormous areas of the cerebrum it is deeply involved in the autonomic nervous system it is identified reflexively and directively with the skeletal musculature from head and hand to foot. Vision is so perva sively bound up with the past and present performances of the organism that it must be interpreted in terms of a total, unitary, integrated action system. The nature of the integration, in turn, can be under stood only through an appreciation of the orderly stages and relativi ties of development whereby the integration itself is progressively at tained. The authors have attempted to achieve a closer acquaintance with the interrelations of the visual system per se and the total action system of the child. This finally entailed the use of the retinoscope and of analytic optornetry at early age levels where these technical procedures ordinarily are not applied. The examinations of the visual functions and of visual skills were really conducted as behavior tests, not only to determine the refractive status of the eyes, but also to determine the reactions of the child as an organism to specific and total test situations. The objective findings have been correlated with the cumulative evi dence furnished by the developmental examinations, numerous inter views, and naturalisticobservations of the children at home and in a guidance nursery. Although the conclusions of our study are prelimi nary in character, we may hope that they will contribute to a better understanding of the child in terms of vision and a better understand ing of vision in terms of the child. The two should not be sundered. With increased knowledge it is possible that the visual behavior of the individual child will become an acute index for the appraisal of fundamental constitutional traits...

The book contains a detailed account of numerical solutions of differential equations of a number of elementary problems of physics using Euler and second order Runge-Kutta methods using Mathematica 6.0. The problems are motion under constant force (free fall), motion under Hooke's law force (simple harmonic motion), motion under combination of Hooke's law force and a velocity dependent damping force (damped harmonic motion) and radioactive decay law. Also included are uses of Mathematica in dealing with complex numbers, in solving system of linear equations, in carrying out differentiation and integration, and in dealing with matrices.

This book demonstrates Microsoft EXCEL(R)-based Fourier transform of selected physics examples, as well as describing spectral density of the auto-regression process in relation to Fourier transform. Rather than offering rigorous mathematics, the book provides readers with an opportunity to gain an understanding of Fourier transform through the examples. They will acquire and analyze their own data following the step-by-step procedure outlined, and a hands-on acoustic spectral analysis is suggested as the ideal long-term student project.

GLACIAL GEOLOGY and the Pleistocene Epoch by Richard Foster Flint Professor of Geology in Yule University New York JOHN WILEY SONS, Inc. London CHAPMAN HALL, Limited To the memory of MAX DEMOREST 1910-1942 Outstanding glaciologist, excellent field companion, generous and thoughtful friend, who died to save the lives of others. November 30, 1942 PREFACE The Pleistocene epoch occupies a peculiarly important place in the time scale of geology, for it embraces the events of the latest million or more years in the history of the Earth and is therefore so recent that it bridges the gap between the geologic changes now in progress and the more remote past. When the work of the geologist is finished, wrote Gilbert, 1 and his final comprehensive report written, the longest and most important chapter will be upon the latest and shortest of the geo logic periods. The chapter will be longest because the exceptional full ness of the record of the latest period will enable him to set forth most completely its complex history. The changes of each period its erosion, its sedimentation, and its metamorphism obliterate part of the records of its predecessor and of all earlier periods, so that the order of our knowledge must continue to be, as it now is, the inverse order of their antiquity. This fact in itself furnishes an adequate reason for making the prin cipal facts of the Pleistocene epoch compactly available, not only to geologists but also to Geologists, archeologists, geographers, and . others whose studies reach back into the prehistoric realm. In addition, the increased pace of research upon Pleistocene problems in general, and problems in glacial geology in particular, that has been evidentduring the last two decades has emphasized the necessity, in this field, of a summary that will be at once a reference to the data already established and a means of indicating the areas and problems in which further research is most needed. These are the principal objectives of the present volume. No one knows better than its author that it falls short of attain ing them. Knowledge of the Pleistocene has grown to such an extent that a complete reference work would become an encyclopedia. The consequent necessity for condensation has required the exercise of selective judgment at every turn. The list of references at the end of the book is far from complete, though an earnest effort has been made to see that it is representative. In particular it may lack important titles that have appeared in some countries during the war years and that have not yet been widely distributed. 1 Gilbert 1890, p. 1. viii PREFACE This discussion treats the Pleistocene frankly from the point of view of glaciation, the outstanding characteristic that distinguishes the Pleisto cene from the epochs that preceded it. The somewhat cumbersome title was selected with this fact in mind, in an effort not to create the impression that the work is a fully balanced treatment of every phase of the Pleistocene. As is pointed out in Chapter 16, the correlations of Pleistocene events cited and suggested are, as far as possible, those based on geologic evidence rather than on archeologic evidence. In the presentation of geologic evidence itself stream-terrace data are used as little as possible in the belief that this class of data is more frequently subject to faulty interpretation than the data obtained from features ofother kinds. In particular this book avoids, in correlation, deduction from any theory of Pleistocene climatic fluctuation which sets up a fixed chronology of events. This conservative attitude is adopted on the principle that only when the stratigraphic column is built up strictly on geologic evidence can the influence of prejudice in favor of a particular theory of climate be avoided...

In 2000 and 2001, twelve northern states of the Federal Republic of Nigeria introduced Islamic criminal law as one of a number of measures aiming at "reintroducing the shari'a." Immediately after its adoption, defendants were sentenced to death by stoning or to amputation of the hand. Apart from a few well publicised trials, however, the number and nature of cases tried under Islamic criminal law are little known. Based on a sample of trials, the present thesis discusses the introduction of Islamic criminal law and the evolution of judicial practice within the regions historical, cultural, political and religious context. The introduction of Islamic criminal law was initiated by politicians and supported by Muslim reform groups, but its potential effects were soon mitigated on higher judicial levels and aspects of the law were contained by local administrators.

Albert Einstein discovered that the motion of all objects in the universe is determined by the structure of space. In The Fundamental Force, author and computer scientist Len Kurzawa reveals the structure of space, and how this structure leads to an understanding of the universe.

With charts, tables, and illustrations, The Fundamental Force provides a step-by-step understanding of what is happening in the universe. With this understanding, unsolved mysteries can now be explained. It discusses:

How gravity works Why the motion of bodies in space follows a pattern Why galaxies rotate like solid objects How galaxies are made and where the matter comes from to make them How the structure of space determines the structure of objects in space The true nature of tides Why planets transition from elliptical to circular orbits Why there is a procession of their orbits How the forces of nature are derived from the one fundamental force

Presenting a unique and thoughtful view of the universe's origin and future, The Fundamental Force changes the way the universe is viewed.
