Problem Solved

The homotopy type of a closed simply connected 4-manifold is determined by the intersection form. The homotopy classes of maps between two such manifolds, however, do not coincide with the algebraic morphisms between intersection forms. Therefore the problem arises of computing the homotopy classes of maps algebraically and determining the law of composition for such maps. This problem is solved in the book by introducing new algebraic models of a 4-manifold. The book has been written to appeal to both established researchers in the field and graduate students interested in topology and algebra. There are many references to the literature for those interested in further reading.

Mathematical modelling is the basis of almost all applied mathematics. A 'real-world' problem is dissected and phrased in a mathematical setting, allowing it to be simplified and ultimately solved. This book presents a thorough grounding in the techniques of modelling, and proceeds to explore a range of classical and continuum models from an impressive array of disciplines, including: biology, chemical engineering, fluid and solid mechanics, geophysics, medicine, and physics. It assumes only a basic mathematical grounding in calculus and analysis and will provide a wealth of examples for students of mathematics, engineering, and the range of applied sciences.

The first edition of this very successful book was one winner of the Astronomical Society of the Pacific 'Astronomy Book of the Year' awards in 1986. There are a further seven subroutines in the new edition which can be linked in any combination with the existing twenty-six. Written in a portable version of BASIC, it enables the amateur astronomer to make calculations using a personal computer. The routines are not specific to any make of machine and are user friendly in that they require only a broad understanding of any particular problem. Since the programs themselves take care of details, they can be used for example to calculate the time of rising of any of the planets in any part of the world at any time in the future or past, or they may be used to find the circumstances of the next solar eclipse visible from a particular place. In fact, almost every problem likely to be encountered by the amateur astronomer can be solved by a suitable combination of the routines given in the bo

The problem of determining which S-arithmetic groups have a finite presentation is solved for arbitrary linear algebraic groups over finite extension fields of #3. For certain solvable topological gro

This is an introductory textbook on spherical and positional astronomy. It is entirely suitable for use by students with no prior knowledge of classical astronomy. At the same time, it is sufficiently comprehensive to make it a useful background reference book for anyone engaged in practical astronomy. The first three chapters sketch essential background: mathematical techniques and coordinate systems. Successive chapters then give treatments of refraction, aberration, stellar parallex, precession, nutation and proper motion. An entire chapter is devoted to astrographic plate measurements. The gravitational two-body problem is solved and applied to solar system dynamics. Novel areas include a full treatment of binary star orbits and two chapters on developments in radio astronomy. Worked examples and problems to be solved by the reader ensure that this is a valuable textbook.

In this short book, the authors discuss three types of problems from combinatorial geometry: Borsuk's partition problem, covering convex bodies by smaller homothetic bodies, and the illumination problem. They show how closely related these problems are to each other. The presentation is elementary, with no more than high-school mathematics and an interest in geometry required to follow the arguments. Most of the discussion is restricted to two- and three-dimensional Euclidean space, though sometimes more general results and problems are given. Thus even the mathematically unsophisticated reader can grasp some of the results of a branch of twentieth-century mathematics that has applications in such disciplines as mathematical programming, operations research and theoretical computer science. At the end of the book the authors have collected together a set of unsolved and partially solved problems that a sixth-form student should be able to understand and even attempt to solve.

This new edition of Ahmed and Spreadbury's excellent textbook Electronics for Engineers provides, like the first edition, an introduction to electronic circuits covering the early part of degree level courses in electronics and electrical engineering. The text of the first edition has been entensively revised and supplemented to bring it up to date; two entirely new chapters have been added on the subject of digital electronics. A first chapter on the general principles of signal handling in electronic circuits is followed by descriptions of amplifiers using field-effect and bipolar transistors and integrated circuit op-amps, written from the point of view of the engineering student building up a system. Subsequent chapters discuss the principles of applying negative and positive feedback in amplifiers, leading the reader to the final two chapters covering digital circuits and their applications. All chapters conclude with a solved problem followed by a number of practice questions fro

This book is a collection of some 400 physics problems, with hints on their solutions, and answers. The physics covered encompasses all areas studies by final-year (advanced level) students in schools and high schools. The author has concentrated on presenting interesting (and to some extent unusual) problems which can be solved using the physical principles normally taught in advanced school courses. By working through the questions, the student will become adept at selecting and applying physical principles appropriate to any particular problem. Problems for Physics Students will provide stimulation and practical help not only for those preparing for pre-university examinations in physics, but also for first-year physics and engineering students studying at universities and other institutions offering first-degree courses. Teachers of physics will find this an invaluable sourcebook for ideas to generate discussion, and for unusual problems to stimulate interest.

An elegant analysis of how animals work and function. Professor Schmidt-Nielsen's incisive account gives a clear understanding of comparative physiology in relation to body size, form and function, energy supply, and environment. The author is concerned with principles. For example, he explains how difficult it may be to lose heat and water from the respiratory tract. This leads to a consideration of the mechanism of panting as a means of heat loss. The author describes the centuries-old problem of how birds breathe, which now has been solved in his laboratory. He then discusses energy expenditure for swimming, running, and flying, and the effects of activity on heat balance. The ability of mammals to maintain different parts of the body at different temperatures is explained on the basis of counter-current heat exchange; a related mechanism permits the fast-swimming tuna to enjoy some of the advantages of being warm-blooded. The problems raised by being small in size, or large, are co

The student or translator of the New Testament will often find difficulties which can only be solved by considering the syntax of the passage concerned. Professor Moule here provides a reference book which gives guidance on such problems of exegesis. It is a work which presupposes a knowledge of Greek and makes frequent allusions to the standard works; it is intended primarily for theological students. After an introductory section on 'The Language of the New Testament' Professor Moule considers in turn particular syntactical divisions (tenses, moods, voices, cases), certain parts of speech and types of clauses, and idiosyncrasies in usage. The last four chapters are 'The order of words', 'Semitisms', 'Latinisms', and 'Miscellaneous notes on style'. In each section New Testament usages are defined and distinguished. A number of examples of each type of problem are discussed. They were chosen as being sufficiently representative to provide a guide to the treatment of similar difficultie
