ELEMENTARY FLUID MECHANICS BY JOHN K. VENNARD Assistant Professor of Fluid Mechanics New York University. PREFACE: Fluid mechanics is the study under all possible conditions of rest and motion. Its approaches analytical, rational, and mathematical rather than empirical it concerns itself with those basic principles which lead to the solution of numerous diversified problems, and it seeks results which are widely applicable to similar fluid situations and not limited to isolated special cases. Fluid mechanics recognizes no arbitrary boundaries between fields of engineering knowledge but attempts to solve all fluid problems, irrespective of their occurrence or of the characteristics of the fluids involved. This textbook is intended primarily for the beginner who knows the principles of mathematics and mechanics but has had no previous experience with fluid phenomena. The abilities of the average beginner and the tremendous scope of fluid mechanics appear to be in conflict, and the former obviously determine limits beyond which it is not feasible to go these practical limits represent the boundaries of the subject which I have chosen to call elementary fluid mechanics. The apparent conflict between scope of subject and beginner f s ability is only along mathematical lines, however, and the physical ideas of fluid mechanics are well within the reach of the beginner in the field. Holding to the belief that physical concepts are the sine qua non of mechanics, I have sacrificed mathematical rigor and detail in developing physical pictures and in many cases have stated general laws only without numerous exceptions and limitations in order to convey basic ideas such oversimplification isnecessary in introducing a new subject to the beginner. Like other courses in mechanics, fluid mechanics must include disciplinary features as well as factual information the beginner must follow theoretical developments, develop imagination in visualizing physical phenomena, and be forced to think his way through problems of theory and application. The text attempts to attain these objectives in the following ways omission of subsidiary conclusions is designed to encourage the student to come to some conclusions by himself application of bare principles to specific problems should develop ingenuity illustrative problems are included to assist in overcoming numerical difficulties and many numerical problems for the student to solve are intended not only to develop ingenuity but to show practical applications as well. Presentation of the subject begins with a discussion of fundamentals, physical properties and fluid statics. Frictionless flow is then discussed to bring out the applications of the principles of conservation of mass and energy, and of impulse-momentum law, to fluid motion. The principles of similarity and dimensional analysis are next taken up so that these principles may be used as tools in later developments. Frictional processes are discussed in a semi-quantitative fashion, and the text proceeds to pipe and open-channel flow. A chapter is devoted to the principles and apparatus for fluid measurements, and the text ends with an elementary treatment of flow about immersed objects.

Meet Mickey, an innocent, screaming that the emperor has no clothes. But no one hears, least of all George, the aristocrat. George has risen high and, with Bill, the guileful ruler, and the US Congress protecting him, his confidence swells. As it is, the circumstances of his life make him feel utterly safe and he becomes blind to the lurking dangers around him. Enter pragmatic Doug - no-nonsense, down-to-earth and pesky. He's one who won't suffer fools and is determined to change the order of things. Now meet Carlo who sets his sights on greatness and Leon who has the audacity to oppose the daring Italian. With elements of the looming conflict in place, the plot rapidly unfolds. Leon joins forces with Doug and Jay - Doug who is lording it over Bill and Jay who has the ear of President Reagan. A conspiracy is set in motion. The science community rumbles, with many crushed in the quaking earth. And the tale fate has writ plays out to its inevitable end.

This book presents research involving learning opportunities that are afforded to learners of science when the focus is on linking the formal and informal science education sectors. It uses the metaphor of a "landscape" as it emphasises how the authors see the possible movement within a landscape that is inclusive of formal, informal and free-choice opportunities. The book explores opportunities to change formal school science education via perspectives and achievements from the informal and free-choice science education sector within the wider lifelong, life-wide education landscape. Additionally it explores how science learning that occurs in a more inclusive landscape can demonstrate the potential power of these opportunities to address issues of relevance and engagement that currently plague the learning of science in school settings. Combining specific contexts, case studies and more general examples, the book examines the science learning landscapes by means of the lens of an ecosystem and the case of the Synergies longitudinal research project. It explores the relationships between school and museum, and relates the lessons learned through encounters with a narwhal. It discusses science communication, school-community partnerships, socioscientific issues, outreach education, digital platforms and the notion of a learning ecology.

This book provides a historical background for the world's current energy problems, describing how the Industrial Revolution has led us to the impending end of the "Age of Fossil Fuels," and describes possible solutions for averting a global crisis. World Energy Crisis: A Reference Handbook provides a thorough investigation of a controversial topic: our current global energy situation, and what actions should be taken to prevent a crippling fuel-supply catastrophe in the future. The book presents a historical background for current energy problems that discusses the supply and consumption of various forms of energy at different periods of history, covering the evolution of energy use in civilization beginning with human muscle power, the successive eras of mechanized industry and transportation, and our current dependence on fossil fuels. The author explains geopolitical factors regarding energy; details controversial new ways of extending the fossil fuel supply, including the exploitation of tar sands and oil shale as well as new technologies like hydraulic fracturing; and examines the various environmental concerns that are integral to extracting energy from natural resources-and the results of consuming them. A bibliographic chapter devoted to print and electronic resources on the topic useful to readers interested in continuing their research on world energy issues Profiles of individuals and organizations with special interests in the world energy crisis 20 tables providing relevant data, such as a list of the years various countries hit "peak oil" (the maximum amount of oil produced in a single year) Primary documents relating to the world energy crisis

ELECTROMAGNETIC THEORY by JULIUS ADAMS STRATTON. PREFACE: The pattern set nearly 70 years ago by Maxwell's Treatise on Electricity and Magnetism has had a dominant influence on almost every subse quent English and American text, persisting to the present day. The Treatise was undertaken with the intention of presenting a connected account of the entire known body of electric and magnetic phenomena from the single point of view of Faraday. Thus it contained little or no mention of the hypotheses put forward on the Continent in earlier years by Riemann, Weber, Kirchhoff, Helmholtz, and others. It is by no means clear that the complete abandonment of these older theories was fortunate for the later development of physics. So far as the purpose of the Treatise was to disseminate the ideas of Faraday, it was undoubtedly fulfilled; as an exposition of the author's own contributions, it proved less successful. By and large, the theories and doctrines peculiar to Maxwell the concept of displacement current, the identity of light and electromagnetic vibrations appeared there in scarcely greater completeness and perhaps in a less attractive form than in the original memoirs. We find that all of the first volume and a large part of the second deal with the stationary state. In fact only a dozen pages are devoted to the general equations of the electromagnetic field, 18 to the propagation of plane waves and the electromagnetic theory of light, and a score more to magnetooptics, all out of a total of 1,000. The mathematical completeness of potential theory and the practical utility of circuit theory have influenced English and American writers in very nearly the same proportion since that day. Onlythe original and solitary genius of Heaviside succeeded in breaking away from this course. For an exploration of the fundamental content of Maxwell's equations one must turn again to the Continent. There the work of Hertz, Poin car6, Lorentz, Abraham, and Sommerfeld, together with their associates and successors, has led to a vastly deeper understanding of physical phenomena and to industrial developments of tremendous proportions. The present volume attempts a more adequate treatment of variable electromagnetic fields and the theory of wave propagation. Some atten tion is given to the stationary state, but for the purpose of introducing fundamental concepts under simple conditions, and always with a view to later application in the general case. The reader must possess a general knowledge of electricity and magnetism such as may be acquired from an elementary course based on the experimental laws of Coulomb, Amp& re, and Faraday, followed by an intermediate course dealing with the more general properties of circuits, with thermionic and electronic devices, and with the elements of electromagnetic machinery, termi nating in a formulation of Maxwell's equations. This book takes up at that point. The first chapter contains a general statement of the equations governing fields and potentials, a review of the theory of units, reference material on curvilinear coordinate systems and the elements of tensor analysis, concluding with a formulation of the field equations in a space-time continuum.

This book is for the reader who takes interest in an age-old issue that remains contemporary with every succeeding generation. When, how, and why we are here are questions that have caused countless generations of thinkers and laymen alike to intuitively seek at the very least the semblance of an answer to questions that have become more of an outlook than a science, and in turn spring up among the problems of modern life as opposed to allowing for a resolution to that which was intended to clarify instead of further complicate. Free from the shackles and bias imposed by the various schools of religious, scientific and philosophical thought, the examinations offered herein are rooted in systematic analyses of the scientific, philosophical, ethical, social and finally the religious; which in turn allows for the explanation and justification of concepts that enable the reader to adopt a perspective relevant to the distinctions of absolute truth and relativistic assumptions. Our age is accurately referred to as the age of advancement and technology and for good reason. The rapid pace of progression over the last century in the life sciences has contributed to a broadened understanding of knowledge itself and its relation to the psychological and sociological aspects of our existence. As a result of the significant expansion of the sciences, the desire for an understanding of "self" and simply of "why" has in many ways been diluted, thus negating the never ending questions that once tugged at man's conscious in the middle of the night for thousands of years. Today's amazing achievements have laid the foundation for a whole series of newer problems and questions that threaten mankind as never before. The medical and biological sciences have enabled us to have a life expectancy beyond that of prior generations, however coupled with that are the problems of population explosion, which in the not too distant future will give rise to serious concerns. We have the ability to harness the power of the atom, yet along with it comes the ability to destroy all that we hold sacred. Taking into consideration the advanced age we live in, how does one account for the remarkable complexity extant throughout the known universe? Is one to assume that our consciousness coupled with our overwhelming sense of purpose can be attributed solely to "random chance" alone? The law of causation deals with the need for a preceding event leading to the outcome, and despite the fact that this scientific age has left its handprint on every facet of life today, it has failed to satisfy the innate question of simply, .............................................. why?

This volume addresses key aspects of the philosophical psychology elaborated by Alexius Meinong and some of his students. It covers a wide range of topics, from the place of psychological investigations in Meinong's unique philosophical program to his thought-provoking views on perception, colors, "Vorstellungsproduktion," assumptions, values, truth, and emotions.

ELECTRICAL MACHINE DESIGN- THE DESIGN AND SPECIFICATION OF DIRECT AND ALTERNATING CURRENT MACHINERY by ALEXANDER GRAY. Originally published in 1913. PREFACE: The following work was compiled as a course of lectures on Electrical Machine Design delivered at Mo Gill University. Since the design of electrical machinery is as much an art as it is science no list of formula or collection of data is sufficient to enable one to become a successful designer. There is a certain amount of data, however, sifted from the mass of material on the subject, which every designer finds convenient to compile for ready reference. This work contains data that the author found necessary to tabulate during several years of experience as a designer of electrical apparatus. A study of design Is of the utmost importance to all students, because only by such a study can a knowledge of the limitations of machines be acquired. The machines discussed are those which have become more or less standard, namely, direct-cur rent generators and motors, alternating current generators, syn chronous motors, polyphase induction motors, and transformers; other apparatus seldom offers an electrical problem that is not discussed under one or more of the above headings. The principle followed throughout the work is to build up the design for the given rating by the use of a few fundamental formula*, and design constants, the meaning and limits of which are discussed thoroughly, and the same procedure has been followed for the several pieces of apparatus.

This book introduces the elements of the theory of real-valued functions of a real variable. The book is aimed at young mathematicians and others who would like to see a coherent account of basic analysis as a rigorous mathematical theory. It aims to avoid various extremes: It does not brush any of the serious difficulties in analysis proper under the carpet. The reader is assumed to be bright, and willing to work hard. It does not dwell on routine stuff. The reader has probably already taken a non-rigorous calculus course, and does not need to be led through that material again.

What if men built a tower from Earth to Heaven-and broke through to Heaven's other side? What if we discovered that the fundamentals of mathematics were arbitrary and inconsistent? What if there were a science of naming things that calls life into being from inanimate matter? What if exposure to an alien language forever changed our perception of time? What if all the beliefs of fundamentalist Christianity were literally true, and the sight of sinners being swallowed into fiery pits were a routine event on city streets?

These are the kinds of outrageous questions posed by the stories of Ted Chiang.
