J. W. Dunne’s An Experiment with Time, first published in 1927, sparked a great debate in the scientific community — as well as a fair amount of controversy. Dunne (1866–1949), an accomplished aeronautical engineer and a designer of military aircraft, experienced a series of strange and vivid dreams that came true with shocking regularity. Using his precognitive dreams as an alternate model of time measurement and its relationship to dreams, Dunne proposed a concept of multidimensional time leading to higher levels of consciousness, and, eventually, immortality. This life-altering insight accounted for many of life’s mysteries: the purpose of dreams and prophecy, the phenomenon of déjà vu, the concept of higher consciousness, and the belief in eternal life.

This unusually well-written, skillfully organized introductory text provides an exhaustive survey of ordinary differential equations — equations which express the relationship between variables and their derivatives. In a disarmingly simple, step-by-step style that never sacrifices mathematical rigor, the authors — Morris Tenenbaum of Cornell University, and Harry Pollard of Purdue University — introduce and explain complex, critically-important concepts to undergraduate students of mathematics, engineering and the sciences.The book begins with a section that examines the origin of differential equations, defines basic terms and outlines the general solution of a differential equation-the solution that actually contains every solution of such an equation. Subsequent sections deal with such subjects as: integrating factors; dilution and accretion problems; the algebra of complex numbers; the linearization of first order systems; Laplace Transforms; Newton's Interpolation Formulas; and Picard's Method of Successive Approximations.The book contains two exceptional chapters: one on series methods of solving differential equations, the second on numerical methods of solving differential equations. The first includes a discussion of the Legendre Differential Equation, Legendre Functions, Legendre Polynomials, the Bessel Differential Equation, and the Laguerre Differential Equation. Throughout the book, every term is clearly defined and every theorem lucidly and thoroughly analyzed, and there is an admirable balance between the theory of differential equations and their application. An abundance of solved problems and practice exercises enhances the value of Ordinary Differential Equations as a classroom text for undergraduate students and teaching professionals. The book concludes with an in-depth examination of existence and uniqueness theorems about a variety of differential equations, as well as an introduction to the theory of determinants and theorems about Wronskians.

Who was Gandhi? In the midst of resurging interest in the man who freed India, inspired the American Civil Rights Movement, and is revered, respected, and misunderstood all over the world, the time is proper to listen to Gandhi himself — in his own words, his own "confessions," his Autobiography. Gandhi made scrupulous truth-telling a religion, and his Autobiography inevitably reminds one of other saints who have suffered and burned for their lapses. He gives a simply narrated account of his boyhood in Gujarat, marriage at age 13, legal studies in England, and a growing desire for purity and reform. He details his gradual conversion to vegetarianism and ahimsa (non-violence) and the state of celibacy (brahmacharya, self-restraint) that became one of his more arduous spiritual trials. Gandhi was a fascinating, complex man, a brilliant leader and guide, a seeker of truth who died for his beliefs but had no use for martyrdom or sainthood. In the political realm he outlines the beginning of Satyagraha in South Africa and India, with accounts of the first Indian fasts and protests, his initial errors and misgivings, his jailings, and continued cordial dealings with the British overlords. Mahatma Gandhi writes of this book: "My purpose is to describe experiments in the science of Satyagraha, not to say how good I am." Satyagraha, Gandhi's nonviolent protest movement (satya = true, agraha = firmness), came to stand, like its creator, as a moral principle and a rallying cry; the principle was truth and the cry freedom. The life of Gandhi has given fire and fiber to freedom fighters and to the untouchables of the world: hagiographers and patriots have capitalized on Mahatma myths. Yet Gandhi writes: "Often the title [Mahatma, Great Soul] has deeply pained me. . . . But I should certainly like to narrate my experiments in the spiritual field which are known only to myself, and from which I have derived such power as I possess for working in the political field." His story, the path to his vision of Satyagraha and human dignity, is a critical work of the twentieth century, and timeless in its courage and inspiration. Dover publishes history books featuring autobiographies and biographies of famous figures, great war battles, politics, various eras, and global cultures and history including Tudor England, Ancient Rome, medieval times, the writings of Gandhi, Lenin, Lincoln, and Machiavelli — books for the scholar and general reader, including many reprints of hard-to-find classics.

His record tracks that memorable experience, describing in picturesque terms the majestic vistas, flora and fauna, and other breathtaking natural wonders of the area.Today Muir is recognized as one of the most important and influential naturalists and nature writers in America. This book, the most popular of the author’s works, will delight environmentalists and nature lovers with its exuberant observations. Read more

The aim of this graduate-level textbook is to present and explain, at other than a superficial level, modem ab initio approaches to the calculation of the electronic structure and properties of molecules. The first three chapters contain introductory material culminating in a thorough discussion of the Hartree-Fock approximation.The remaining four chapters describe a variety of more sophisticated approaches, which improve upon this approximation.Among the highlights of the seven chapters are (1) a review of the mathematics (mostly matrix algebra) required for the rest of the book, (2) an introduction to the basic techniques, ideas, and notations of quantum chemistry, (3) a thorough discussion of the Hartree-Fock approximation, (4) a treatment of configuration interaction (Cl) and approaches incorporating electron correlation, (5) a description of the independent electron pair approximation and a variety of more sophisticated approaches that incorporate coupling between pairs, (6) a consideration of the perturbative approach to the calculation of the correlation energy of many-electron systems and (7) a brief introduction to the use of the one-particle many-body Green's function in quantum chemistry.Over 150 exercises, designed to help the reader acquire a working knowledge of the material, are embedded in the text. The book is largely self-contained and requires no prerequisite other than a solid undergraduate physical chemistry course; however, some exposure to quantum chemistry will enhance the student's appreciation of the material. Clear and well-written, this text is ideal for the second semester of a two-semester course in quantum chemistry, or for a special topics course. Read more

Written by a distinguished mathematician and teacher, this undergraduate text uses a combinatorial approach to accommodate both math majors and liberal arts students. In addition to covering the basics of number theory, it offers an outstanding introduction to partitions, plus chapters on multiplicativity-divisibility, quadratic congruences, additivity, and more. Although mathematics majors are usually conversant with number theory by the time they have completed a course in abstract algebra, other undergraduates, especially those in education and the liberal arts, often need a more basic introduction to the topic. In this book, the author solves the problem of maintaining the interest of students at both levels by offering a combinatorial approach to elementary number theory. Among the topics covered in this accessible, carefully designed introduction are:Multiplicativity-divisibility, including the fundamental theorem of arithmeticCombinatorial and computational number theoryCongruences, arithmetic functions, primitive roots and prime numbersLater chapters offer lucid treatments of quadratic congruences, additivity (including partition theory), and geometric number theory Of particular importance in this text is the author's emphasis on the value of numerical examples in number theory and the role of computers in obtaining such examples. Exercises provide opportunities for constructing numerical tables with or without a computer. Students can then derive conjectures from such numerical tables, after which relevant theorems will seem natural and well-motivated. Dover is widely recognized for a magnificent mathematics list featuring such world-class theorists as Paul J. Cohen (Set Theory and the Continuum Hypothesis), Alfred Tarski (Undecidable Theories), Gary Chartrand (Introductory Graph Theory), Hermann Weyl (The Concept of a Riemann Surface), Shlomo Sternberg (Dynamical Systems), and multiple works by C. R. Wylie in geometry, plus Stanley J. Farlow's Partial Differential Equations for Scientists and Engineers. Read more

"My heart always sinks within me when I hear the good housewife, of every class, say, 'I assure you the bed has been well slept in,' and I can only hope it is not true. What? Is the bed already saturated with somebody else's damp before my patient comes to exhale in it his own damp? Has it not had a single chance to be aired? No, not one. It has been slept in every night."From the best known work of Florence Nightingale (1820–1910), the originator and founder of modern nursing, comes a collection of notes that played an important part in the much needed revolution in the field of nursing. For the first time it was brought to the attention of those caring for the sick that their responsibilities covered not only the administration of medicines and the application of poultices, but the proper use of fresh air, light, warmth, cleanliness, quiet, and the proper selection and administration of diet. Miss Nightingale is outspoken on these subjects as well as on other factors that she considers essential to good nursing. But, whatever her topic, her main concern and attention is always on the patient and his needs.One is impressed with the fact that the fundamental needs of the sick as observed by Miss Nightingale are amazingly similar today (even though they are generally taken for granted now) to what they were over 100 years ago when this book was written. For this reason, this little volume is as practical as it is interesting and entertaining. It will be an inspiration to the student nurse, refreshing and stimulating to the experienced nurse, and immensely helpful to anyone caring for the sick. Read more

"An excellent text, highly recommended." — ChoiceWhen it was first published, this first-year chemistry text revolutionized the teaching of chemistry by presenting it in terms of unifying principles instead of as a body of unrelated facts. Those principles included modern theories of atomic and molecular structure, quantum mechanics, statistical mechanics, and thermodynamics. In addition, Dr. Pauling attempted to correlate the theories with descriptive chemistry, the observed properties of substances, to introduce the student to the multitude of chemical substances and their properties.In this extensively revised and updated third edition, the Nobel Prize–winning author maintains an excellent balance between theoretical and descriptive material, although the amount of descriptive chemistry has been decreased somewhat, and the presentation of the subject, especially in relation to the nonmetals, has been revised in such a way as to permit greater correlation with the electronic structure of atoms, especially electronegativity.The principles of quantum mechanics are discussed on the basis of the de Broglie wavelength of the electron. The quantized energy levels of a particle in a box are derived by means of a simple assumption about the relation of the de Broglie waves to the walls of the box. No attempt is made to solve the Schrödinger wave equation for other systems, but the wave functions of hydrogen-like electrons are presented and discussed in some detail, and the quantum states for other systems are also covered. Statistical mechanics is introduced before thermodynamics, and the discussion of thermodynamics is based on it. This arrangement reflects the author's belief that beginning students can understand statistical mechanics better than chemical thermodynamics. Aimed at first-year college students who plan to major in chemistry or closely related fields, the book is written in a logical, clear, and understandable style. In addition, many excellent figures are included, along with numerous problems and 75 pages of appendices covering such topics as symmetry of molecules and crystals, hybrid bond orbitals, and magnetic properties of substances.

"Most useful in working with wing sections and methods for using section data to predict wing characteristics . . . much detailed geometric and aerodynamic data." — Mechanical EngineeringThe first edition of this work has been corrected and republished in answer to the continuing demand for a concise compilation of the subsonic aerodynamics characteristics of modern NASA wing sections together with a description of their geometry and associated theory. These wing sections, or their derivatives, continue to be the ones most commonly used for airplanes designed for both subsonic and supersonic speeds, and for helicopter rotor blades, propeller blades, and high performance fans.Intended to be primarily a reference work for engineers and students, the book devotes over 300 pages to theoretical and experimental considerations. The theoretical treatment progresses from elementary considerations to methods used for the design of NACA low-drag airfoils. Methods and data are presented for using wingsection data to predict wing characteristics, and judiciously selected plots and cross-plots of experimental data are presented for readily useful correlation of certain simplifying assumptions made in the analyses. The chapters on theory of thin wings and airfoils are particularly valuable, as is the complete summary of the NACA's experimental observations and system of constructing families of airfoils. Mathematics has been kept to a minimum, but it is assumed that the reader has a knowledge of differential and integral calculus, and elementary mechanics.The appendix of over 350 pages contains these tables: Basic Thickness Forms, Mean Lines, Airfoil Ordinates, and Aerodynamic Characteristics of Wing Sections.

Written for an engineering audience, this book has a threefold purpose: (1) to present elements of modern probability theory — discrete, continuous, and stochastic; (2) to present elements of information theory with emphasis on its basic roots in probability theory; and (3) to present elements of coding theory.The emphasis throughout the book is on such basic concepts as sets, the probability measure associated with sets, sample space, random variables, information measure, and capacity. These concepts proceed from set theory to probability theory and then to information and coding theories. No formal prerequisites are required other than the usual undergraduate mathematics included in an engineering or science program. However, since these programs may not include a course in probability, the author presents an introductory treatment of probability for those who wish to pursue the general study of statistical theory of communications. The book is divided into four parts: memoryless discrete themes, memoryless continuum, schemes with memory, and an outline of some recent developments. An appendix contains notes to help familiarize the reader with the literature in the field, while the inclusion of many reference tables and an extensive bibliography with some 200 entries makes this an excellent resource for any student in the field.

How to win a woman and how to keep her. How to attract a man and keep him interested. How to get over a love gone wrong. Human nature hasn't changed much over the past 2,000 years, and this new translation constitutes a fresh, accessible approach to the Roman poet's witty guide to seduction—a classic that became the model for nearly every latter-day book on romantic advice. Translator Stanley Appelbaum presents an Introduction that discusses Ovid's life and works. This edition also features twelve plates of erotic artwork from a privately published volume of the 1930s.

This graduate-level text is intended for any student of physics who requires a thorough grounding in the quantum theory of nonrelativistic scattering. It is designed for readers who are already familiar with the general principles of quantum mechanics and who have some small acquaintance with scattering theory. Study of this text will allow students of atomic or nuclear physics to begin reading the literature and tackling real problems, with a complete grasp of the underlying principles. For students of high-energy physics, it provides the necessary background for later study of relativistic problems.Topics are presented in terms of the simplest relevant example, so that scattering theory can be learned by becoming familiar with all of the basic concepts — the S operator, cross sections, the T matrix, and so forth — in their simplest context. The time-dependent approach to the subject is emphasized, starting with the use of time-dependent formalism to define all of the basic concepts and the subsequent introduction of the time-independent theory as a tool for computation and for establishing certain general properties. Problems at the end of each chapter improve and supplement readers' grasp of the material. Read more

This incisive text provides a basic undergraduate-level course in modern optics for students in physics, technology and engineering. The first half of the book deals with classical physical optics; the second principally with the quantum nature of light. Chapters 1 and 2 treat the propagation of light waves, including the concepts of phase and group velocities, and the vectorial nature of light. Chapter 3 applies the concepts of partial coherence and coherence length to the study of interference, and Chapter 4 takes up multiple-beam interference and includes Fabry-Perot interferometry and multilayer-film theory. Diffraction and holography are the subjects of Chapter 5, and the propagation of light in material media (including crystal and nonlinear optics) are central to Chapter 6. Chapters 7 and 8 introduce the quantum theory of light and elementary optical spectra, and Chapter 9 explores the theory of light amplification and lasers. Chapter 10 briefly outlines ray optics in order to introduce students to the matrix method for treating optical systems and to apply the ray matrix to the study of laser resonators.Many applications of the laser to the study of optics are integrated throughout the text. The author assumes students have had an intermediate course in electricity and magnetism and some advanced mathematics beyond calculus. For classroom use, a list of problems is included at the end of each chapter, with selected answers at the end of the book. Read more
