Non-Equilibrium Thermodynamics
Par P. Mazur, S. R. Groot. 1984
The study of thermodynamics is especially timely today, as its concepts are being applied to problems in biology, biochemistry, electrochemistry,…
and engineering. This book treats irreversible processes and phenomena -- non-equilibrium thermodynamics.S. R. de Groot and P. Mazur, Professors of Theoretical Physics, present a comprehensive and insightful survey of the foundations of the field, providing the only complete discussion of the fluctuating linear theory of irreversible thermodynamics. The application covers a wide range of topics: the theory of diffusion and heat conduction, fluid dynamics, relaxation phenomena, acoustical relaxation, and the behavior of systems in an electromagnetic field.The statistical foundations of non-equilibrium thermodynamics are treated in detail, and there are special sections on fluctuation theory, the theory of stochastic processes, the kinetic theory of gases, and the derivation of the Onsager reciprocal relations. The implications of causality conditions and of dispersion relations are analyzed in depth.Advanced students will find a great number of challenging problems, with hints for their solutions. Chemists will be especially interested in the applications to electrochemistry and the theory of chemical reactions. Physicists, teachers, scholars, biologists, and anyone interested in the principle and modern applications of non-equilibrium thermodynamics will find this classic monograph an invaluable reference.Foundations of Laser Spectroscopy
Par Stig Stenholm. 2005
One of the first texts to offer a simple presentation of the theoretical foundations of steady-state laser spectroscopy, this volume…
is geared toward beginning theorists and experimentalists. It assists students in applying theoretical ideas to actual calculations in laser spectroscopy with a systematic series of examples and exercises. Starting at an elementary level, students gradually build up their practical skills with demonstrations of how simplified theoretical models relate to experimentally observable quantities. Detailed derivations offer students the opportunity to work out all results for themselves.The first chapter introduces background material on electrodynamics and quantum mechanics, with an emphasis on the density matrix, its equation of motion, and its interpretation. Chapter 2 derives the response of the medium to strong fields. After mastering these two parts, students can proceed to later chapters in any order they wish. Succeeding chapters cover the physical basis of laser operation, applications central to laser spectroscopy, the inclusion of laser fluctuations into the theory, and field quantization. Numerous references, which appear in separate sections, form a concise history of the field and its most noteworthy developments.Mathematical Methods for Physicists and Engineers: Second Corrected Edition

This practical, highly readable text provides physics and engineering students with the essential mathematical tools for thorough comprehension of their…
disciplines. Featuring all the necessary topics in applied mathematics in the form of programmed instruction, the text can be understood by advanced undergraduates and beginning graduate students without any assistance from the instructor. Topics include elementary vector calculus, matrix algebra, and linear vector operations; the many and varied methods of solving linear boundary value problems, including the more common special functions of mathematical physics; the calculus of variations, and variational and perturbation approximations applicable to boundary value problems and nonlinear differential equations; curve fitting and numerical approximation methods; the basic elements of probability and their application to physical problems; and integral equations. Rather than aiming at a complete mastery of these complicated subjects, the text focuses on the fundamental applied mathematics the student needs to deal with physics and engineering problems. Instructors in those subjects will particularly appreciate this volume's function as a self-contained study resource, allowing them to devote fewer classroom hours to formal lectures in mathematics.Lasers and Holography

As the words holo (complete) and gram (message) connote, the hologram captures the entire message of a scene in all…
its visual properties, including the realism of three dimensions. It involves the simple process of photographically recording the pattern formed by two interfering sets of light waves, one of these sets being a reference wave. With the introduction of lasers to holography in 1963, real advances in the development of holography began to take place.Dr. Kock's lucid introduction to lasers and holography has now been revised and updated for a second edition. It begins with a clear discussion of wave patterns and coherence. Then the development of lasers is summarized, along with the phenomenon of wave diffraction. Finally, the important subjects of zone plates and the properties of holograms are skillfully described. A new, concluding chapter brings the story up to the present, with a survey of recent advances in such areas as viewing holograms, hologram computer memories, liquid surface holography, synthetic-aperture radar and sonar, large new lasers, fiber optics, etc. Using language that can be readily understood by high school and junior high school students, Dr. Kock has written a brief, yet authoritative volume that should satisfy anyone's curiosity about this burgeoning field. The remarkable discoveries that have already occurred are only a prelude to an even more remarkable future. 84 illustrations, including 8 new to this edition. New preface. Suggested (1981) additional reading. Index.The Mammoth Book of Irish Humour
Par Aubrey Malone. 2012
This bumper collection of Irish humour covers topics such as Absenteeism and Zoos and everything in between. It would be…
disappointing should such a large collection not include the best of famous Irish wits such as Oscar Wilde and George Bernard Shaw, but the emphasis is very much on contemporary Irish humour from the likes of Tommy Tiernan, Dylan Moran, Ardal O'Hanlon and Dara O'Briain, to name just a few. Lunatic, iconoclastic and, as Spike Milligan might have put it, involving 'sideways thinking', this is Irish humour at its very best.Principles of Thermodynamics and Statistical Mechanics
Par D. F. Lawden. 1987
A thorough exploration of the universal principles of thermodynamics and statistical mechanics, this volume explains the applications of these essential…
rules to a multitude of situations arising in physics and engineering. It develops their use in a variety of circumstances--including those involving gases, crystals, and magnets--in order to illustrate general methods of analysis and to provide readers with all the necessary background to continue in greater depth with specific topics.Author D. F. Lawden has considerable experience in teaching this subject to university students of varied abilities and backgrounds. Well acquainted with which concepts and arguments sometimes prove problematic, he presents the potentially difficult sections with particular care. Students can supplement their understanding by working through the numerous exercises which appear throughout the text. Mathematical physicists will find this volume of particular value, as will engineers requiring a basic but comprehensive introduction to the principles of thermodynamics and statistical mechanics.Electromagnetism
Par John C. Slater, Nathaniel H. Frank. 1947
Clearly developed from first principles, this introductory study supplies basic material on electrostatics and magnetostatics, then concentrates on electromagnetic theory…
-- the authors are both leading men in the field. The book ranges freely over many areas of electromagnetic theory with some concern for electrical engineering. It covers the field theory of electromagnetism, electrostatics and the equations and theorems of Gauss, Poisson, Laplace and Green, solutions of Laplace's equation, dielectrics, magnetic fields of linear and circular currents, electromagnetic induction and Maxwell's equations, electromagnetic waves, electron theory, wave guides and cavity resonators, spherical electromagnetic waves, Huygen's principle and Green's theorem, and Fresnel and Fraunhofer diffraction. Practice problems are supplied at chapter ends.Physicists and engineers will find this presentation particularly useful; but mathematicians have also used the book not only as an introduction to electromagnetism, but also as a means to an increased knowledge of the aims and tools of theoretical physics. The only background required to follow the development is a knowledge of the calculus and differential equations. More advanced mathematics is developed in appendixes.Philosophic Foundations of Quantum Mechanics
Par Hans Reichenbach. 1944
Physics concerns direct analysis of the physical world, while philosophy analyzes knowledge about the physical world. This volume combines both…
disciplines for a philosophical interpretation of quantum physics -- an interpretation free from the imprecision of metaphysics, offering a view of the atomic world and its quantum mechanical results as concrete as the visible everyday world.Written by an internationally renowned philosopher who specialized in symbolic logic and the theory of relativity, this approach consists of three parts. The first section, which requires no background in math or physics, reviews the basics of quantum mechanics, outlining their philosophical interpretation and summarizing their results. The second part, which presupposes a knowledge of calculus, outlines the mathematical methods of quantum mechanics; and the third part blends the philosophical ideas of the first part and the mathematical formulations of the second part to develop a variety of interpretations of quantum mechanics. The author presents in-depth discussions of each interpretation, constructing a conclusion in terms of three-valued logic that offers readers a satisfactory logical form of quantum mechanics.Focusing on clarification of concepts rather than developing problem-solving skills, this volume will prove enlightening to students of mathematics, physics, and the other sciences.The Lightning Discharge
Par Martin A. Uman. 2001
In this readable, absorbing, up-to-date monograph, one of the nation's foremost experts on lightning sets forth most of what has…
been learned about the subject. To make the material more easily understandable, the author has organized the chapters primarily by lightning process. Following a general introduction and chapters on lightning phenomenology and cloud and lightning charges, he looks into the types and stages of lightning, with chapters on the stepped leader, the attachment process, the return stroke, the dart leader, continuing current, J- and K-processes in discharges to the ground, positive lightning, upward lightning and the artificial initiation of lightning, and cloud discharges. In the final two chapters, Dr. Uman investigates lightning on other planets and examines the phenomenon of thunder.Each chapter contains a reference list, and the book as a whole is augmented with a generous selection of diagrams, charts, and photographs. Appendices on electromagnetics, statistics, and experimental techniques help to clarify some of the concepts covered in the text. A fourth appendix lists relevant books. Of special interest to physicists, meteorologists, and electrical engineers, the newly corrected edition of this detailed study offers a deep understanding of one of nature's most intriguing phenomena. 144 illustrations. Appendices. Index.Variational Principles in Dynamics and Quantum Theory
Par Wolfgang Yourgrau, Stanley Mandelstam. 1968
Concentrating upon applications that are most relevant to modern physics, this valuable book surveys variational principles and examines their relationship…
to dynamics and quantum theory. Stressing the history and theory of these mathematical concepts rather than the mechanics, the authors provide many insights into the development of quantum mechanics and present much hard-to-find material in a remarkably lucid, compact form.After summarizing the historical background from Pythagoras to Francis Bacon, Professors Yourgrau and Mandelstram cover Fermat's principle of least time, the principle of least action of Maupertuis, development of this principle by Euler and Lagrange, and the equations of Lagrange and Hamilton. Equipped by this thorough preparation to treat variational principles in general, they proceed to derive Hamilton's principle, the Hamilton-Jacobi equation, and Hamilton's canonical equations.An investigation of electrodynamics in Hamiltonian form covers next, followed by a resume of variational principles in classical dynamics. The authors then launch into an analysis of their most significant topics: the relation between variational principles and wave mechanics, and the principles of Feynman and Schwinger in quantum mechanics. Two concluding chapters extend the discussion to hydrodynamics and natural philosophy.Professional physicists, mathematicians, and advanced students with a strong mathematical background will find this stimulating volume invaluable reading. Extremely popular in its hardcover edition, this volume will find even wider appreciation in its first fine inexpensive paperbound edition.Pun Direction

Funny, fearless and absolutely filthy-nearly 3,000 more uncensored, dirty, sick, and deeply politically incorrect jokes, covering just about every topic…
imaginable, from adultery to (sex in) Zoos, including an assortment of bad taste lists. A worthy, all-new follow-on to the first bestselling volume.Sorting Out Billy
Par Jo Brand. 2004
Billy is a lad. He's a laugh, he's loud, he behaves badly and Sarah is besotted with him. But after…
another 'accident' involving Billy's temper, Sarah's face and a night in the A&E, Sarah's friends Martha and Flower decide that it's time to take action. What should they do? Reason with him? Send him to anger management classes? Hire a hit man? Martha and Flower have problems of their own: Martha is seven months pregnant by one of three possible blokes (she did this mainly to wind up her sanctimonious vicar father); and hippie Flower's career as a stand-up comic is more sit-down after some nasty encounters with south London's finest hecklers. Will Martha survive single-motherhood on a council estate in need of a peace-keeping force? Will Flower find the perfect put-down? And will they sort out Billy before he gets to them first...? Jo Brand tells it like it is in her darkly comic and sharply observed debut novel.Electromagnetic Fields and Waves
Par Vladimir Rojansky. 1971
Intended for advanced undergraduate and graduate students, this well-known and popular textbook provides an introduction to the physical principles, mathematical…
apparatus, and typical applications of classical electromagnetic theory. Beginning with the notion of scalar fields, Professor Rojansky leads the student through vectors and vector fields, the laws of Ohm, Joule, Coulomb, and Faraday, static electricity, and continues all the way to Maxwell's equations for bodies at rest, and to examples of electromagnetic waves. A particularly useful feature of the book is the author's introduction and explanation of the necessary mathematics as he goes along, rather than presuming student understanding. Although an extensive background is not necessary, a general knowledge of physics and calculus is a prerequisite. Throughout the book, the development of each topic is explicit and unhurried, an approach intended to avoid basic misconceptions that lead to major misunderstandings later on. Short exercises help the student test his grasp of the material, and the text is studded with diagrams and illustrations that supplement the content and elucidate many hard-to-visualize concepts. The book ends at a point where the use of Maxwell's equations in several important problems has been illustrated, and students are prepared to proceed to a variety of further topics. Professor Rojansky brings many years of experience both as a teacher and a scientist (including ten years of advanced research at TRW Space Technologies Laboratories) to this lucid discussion of the fundamentals of electromagnetic fields and waves. His extensive pedagogical background enables him to communicate difficult concepts with great clarity.The Theory of Sound, Volume One
Par J. W. Rayleigh. 1945
The Nobel Laureate's classic sums up all research in the field prior to 1877, then presents Rayleigh's own original contributions.Volume…
One covers harmonic vibrations, systems with one degree of freedom, vibrating systems in general, transverse vibrations of strings, longitudinal and torsional vibrations of bars, vibrations of membranes and plates, curved shells and plates, and electrical vibrations.It's Different For Girls
Par Jo Brand. 2005
A wonderfully funny and poignant novel about growing up in the seventies, teenage angst, growing pains and first love. Rachel…
and Susan do not like to be beside the seaside. Hastings is so uncool. Plunging headfirst into the choppy waters of adolescence, they are determined to survive their teens by sticking together. It?s a rollercoaster ride of nutty parents, randy language students, stoned hippies, all-night parties on the pier, and an amusement arcade of emotional neediness.Theory of Electromagnetic Wave Propagation
Par Charles Herach Papas. 1988
While there are so many books on general electromagnetic theory for graduate-level students, there are significantly fewer that concentrate on…
the radiation aspects as does this well-known work. Interfacing physics and electrical engineering, Dr. Papas's clearly written text discusses highly important topics in the theory of electromagnetic wave propagation and antennas in a way that reveals the inherent simplicity of the basic ideas and their logical development from the Maxwell field equation.Chapter 1: Maxwell's field equations and those parts of electromagnetic field theory necessary for understanding the remainder of the book.Chapter 2: How the dyadic Green's function can be used to compute radiation from monochromatic sources.Chapter 3: Problems of radiation emitted by wire antennas and antenna arrays from the viewpoint of analysis and synthesis.Chapter 4: Two methods of expanding a radiation field in multiples -- one based on the Taylor expansion of the Helmholtz integrals and the other, on all expansion in spherical waves.Chapter 5: Wave aspects of radio-astronomical antenna theory.Chapter 6: Theory of electromagnetic wave propagation in a plasma medium describing the behavior of an antenna immersed in such a medium.Chapter 7: Covariance of Maxwell's equations in material media and its application to phenomena such as the Doppler effect.By unifying various topics under the single mantle of electromagnetic theory, Professor Papas has made the contents of this book easy to learn and convenient to teach. In addition, the book assembles much data previously available only in scattered research literature. The result is a superb graduate-level text that can also lend itself to self-instruction by researchers.Letts Rip!
Par Quentin Letts. 2010
Throughout the New Labour years - that decade of deceit, that era of wretched wriggle - the Daily Mail's Quentin…
Letts has maintained a lonely, vehement vigil. Like a lone clay pigeon shot squinting through his sights at a sky black with targets, he has fired his daily bullets at the poseurs and pooh-bahs of British public life.John Prescott? BANG! Alan Sugar? BANG BANG!Peter Mandelson, Harriet Harman, and the Commons Speaker Letts nicknamed 'Gorbals Mick'? Bullseyes - every single one.In this collection of anguished and often snortingly funny political sketches and journalism, Letts lets off more steam than a Chinese laundry. The modern Establishment won't like it. They tried to gag him. Smear him. Even tried to get him fired. Quentin Letts: The man they could not silence. As his wife will be the first to tell you.Elementary Wave Optics
Par Robert H. Webb. 1997
This undergraduate textbook presents thorough coverage of the standard topics of classical optics and optical instrument design; it also offers…
significant details regarding the concepts of modern optics. Its survey of the mathematical tools of optics grants students insights into the physical principles of quantum mechanics.Two principal concepts occur throughout: a treatment of scattering from real scatterers (leading to Huygens' principles, diffraction theory, the index of refraction, and related topics); and the difference between coherent and noncoherent wave phenomena. Examinations of superimposition of field amplitudes and detection of intensities recur throughout the book.This highly physical approach is augmented by extensive appendixes of mathematical details. Two sets of problems appear at the end of each chapter and form a crucial part of the exposition. One set consists of well-tested problems with detailed solutions, paired with similar problems without supplied solutions. The other set contains short, easier exercises, filling the more conventional role of end-of-chapter problems.Feisty First Ladies and Other Unforgettable White House Women
Par Autumn Stephens. 2009
First ladies are supposed to be dignified background figures, quietly supportive of their husbands' agendas. Above all, they're not supposed…
to act out or cause even a whiff of scandal. Of course, reality often overrides conventional wisdom, and this book shows how far from the prim ideal many of the Presidents' wives have strayed. Part irreverent portrait gallery, part exuberant expose, Feisty First Ladies and Other Unforgettable White House Women introduces a remarkable array of wild women, from Martha Washington, who opposed her own husband's presidential election; to Abraham Lincoln's eccentric wife, Mary; to rebellious daughters like Patti Davis who were the tabloid fodder of their day. Laugh-out-loud funny and filled with amazing stranger-than-fiction facts from our American history, Feisty First Ladies journeys into the realm of the eclectic sisterhood whose outrageous words and deeds have rocked the fusty old foundations of the White House -- and the nation!
