Symmetry in Science: An Introduction to the General Theory

Symmetry in Science: An Introduction to the General Theory by Joseph Rosen
English | PDF | 1995 | 223 Pages | ISBN : N/A | 18.5 MB

Symmetry plays an essential role in science - not only in crystallography and quantum theory, where its role has long been explicitly recognized, but also in condensed-matter physics, thermodynamics, chemistry, biology, and others. This text discusses the concept of symmetry and its application to many areas of science. While it includes a detailed introduction to the theory of groups, which forms the mathematical apparatus for describing symmetries, it also includes a much more general discussion of the nature of symmetry and its role in science. Many problems serve to sharpen the reader's understanding, and an extensive bibliography concludes the book.

Conservation Laws in Variational Thermo-Hydrodynamics

Conservation Laws in Variational Thermo-Hydrodynamics by Stanislaw Sieniutycz
English | PDF | 1994 | 467 Pages | ISBN : 0792328027 | 46.1 MB

This study is one of the first attempts to bridge the theoretical models of variational dynamics of perfect fluids and some practical approaches worked out in chemical and mechanical engineering in the field newly called thermo-hydrodynamics. In recent years, applied mathematicians and theoretical physicists have made significant progress in formulating analytical tools to describe fluid dynamics through variational methods. These tools are much loved by theoretists, and rightly so, because they are quite powerful and beautiful theoretical tools. Chemists, physicists and engineers, however, are limited in their ability to use these tools, because presently they are applicable only to "perfect fluids" (i. e. those fluids without viscosity, heat transfer, diffusion and chemical reactions). To be useful, a model must take into account important transport and rate phenomena, which are inherent to real fluid behavior and which cannot be ignored. This monograph serves to provide the beginnings of a means by which to extend the mathematical analyses to include the basic effects of thermo-hydrodynamics. In large part a research report, this study uses variational calculus as a basic theoretical tool, without undo compromise to the integrity of the mathematical analyses, while emphasizing the conservation laws of real fluids in the context of underlying thermodynamics –reversible or irreversible. The approach of this monograph is a new generalizing approach, based on Nother's theorem and variational calculus, which leads to the energy-momentum tensor and the related conservation or balance equations in fluids.

Nonlinear Fokker-Planck Equations: Fundamentals and Applications by Till Daniel Frank
English | PDF | 2005 | 413 Pages | ISBN : 3540212647 | 2.8 MB

Providing an introduction to the theory of nonlinear Fokker-Planck equations, this book discusses fundamental properties of transient and stationary solutions, emphasizing the stability analysis of stationary solutions by means of self-consistency equations, linear stability analysis, and Lyapunov's direct method. Also treated are Langevin equations and correlation functions. Nonlinear Fokker-Planck Equations addresses various phenomena such as phase transitions, multistability of systems, synchronization, anomalous diffusion, cut-off solutions, travelling-wave solutions and the emergence of power law solutions. A nonlinear Fokker-Planck perspective to quantum statistics, generalized thermodynamics, and linear nonequilibrium thermodynamics is given. Theoretical concepts are illustrated where possible by simple examples. The book also reviews several applications in the fields of condensed matter physics, the physics of porous media and liquid crystals, accelerator physics, neurophysics, social sciences, population dynamics, and computational physics.

Information is Energy: Definition of a physically based concept of information

Information is Energy: Definition of a physically based concept of information by Lienhard Pagel
English | PDF EPUB (True) | 2023 | 230 Pages | ISBN : 3658408618 | 9.1 MB

An objective, dynamic and physically justified concept of information is elaborated starting from Shannon's concept of entropy and applied to information technology, artificial intelligence (consciousness) and thermodynamics. The justification of an information conservation theorem acquires practical significance in information technology, especially as it moves into the quantum realm (photonics/quantum computing). The unconditional dynamics of information and its objectivity are critically examined and are the foundations of the considerations.

Selected Aerothermodynamic Design Problems of Hypersonic Flight Vehicles

Selected Aerothermodynamic Design Problems of Hypersonic Flight Vehicles by Ernst Heinrich Hirschel , Claus Weiland
English | PDF (True) | 2009 | 522 Pages | ISBN : 3540899731 | 75.7 MB

This volume addresses selected aerothermodynamic design problems for three vehicle classes: winged reentry, non-winged reentry, and airbreathing hypersonic flight vehicles. Following an introductory chapter, the book presents the basics of flight trajectory mechanics, giving the aerothermodynamicist an understanding of the principal issues relevant to the field. In the following chapters, specific aerothermodynamic phenomena are discussed for the three vehicle classes, major simulation problems are singled out, and particular trends are examined. Available coefficients of longitudinal motion are presented for a variety of shapes of operational and studied vehicles, and aerothermodynamic issues of stabilization, trim, and control devices are treated.

Mathematical Analysis of Problems in the Natural Sciences by Vladimir Zorich
English | PDF | 2011 | 132 Pages | ISBN : 3642148123 | 1.3 MB

Vladimir A. Zorich is a distinguished Professor of Mathematics at the University of Moscow who solved the problem of global homeomorphism for space quasi-conformal mappings and provided its far-reaching generalizations. In Mathematical Analysis of Problems in Natural Sciences, he uses a lively and accessible style to unify three topics of analysis and physics, which are as follows: the dimensional analysis of physical quantities, which contains various applications including Kolmogorov's model for turbulence; functions of very large numbers of variables and the principle of concentration along with the non-linear law of large numbers, the geometric meaning of the Gauss and Maxwell distributions, and the Kotelnikov-Shannon theorem; and, finally, classical thermodynamics and contact geometry, which covers two main principles of thermodynamics in the language of differential forms, contact distributions, the Frobenius theorem and the Carnot-Caratheodory metric.

Quantum Theory: Concepts and Methods

Quantum Theory: Concepts and Methods by Asher Peres
English | PDF (True) | 463 Pages | ISBN : 0792325494 | 4.5 MB

There are many excellent books on quantum theory from which one can learn to compute energy levels, transition rates, cross sections, etc. The theoretical rules given in these books are routinely used by physicists to compute observable quantities. Their predictions can then be compared with experimental data. There is no fundamental disagreement among physicists on how to use the theory for these practical purposes. However, there are profound differences in their opinions on the ontological meaning of quantum theory. The purpose of this book is to clarify the conceptual meaning of quantum theory, and to explain some of the mathematical methods which it utilizes.

Statistical Physics by A. M. Guénault
English | PDF | 1988 | 197 Pages | ISBN : 0415002591 | 13.3 MB

Statistical physics is not a difficult subject, and I trust that this will not be found a difficult book. It contains much that a number of generations of Lancaster students have studied with me, as part of their physics honours degree work. The lecture course was of twenty hours duration, and I have added comparatively little to the lecture syllabus. A pre­ requisite is that the reader should have a working knowledge of basic thermal physics (i.e. the laws of thermodynamics and their application to simple substances). The book Thermal Physics by Colin Finn in this series forms an ideal introduc tion.

Elementary Statistical Thermodynamics: A Problems Approach

Elementary Statistical Thermodynamics: A Problems Approach by Norman O. Smith
English | PDF | 1982 | 221 Pages | ISBN : 0306412160 | 7.1 MB

This book is a sequel to my Chemical Thermodynamics: A Prob­ lems Approach published in 1967, which concerned classical thermodynamics almost exclusively. Most books on statistical thermodynamics now available are written either for the superior general chemistry student or for the specialist. The author has felt the need for a text which would bring the intermediate reader to the point where he could not only appreciate the roots of the subject but also have some facility in calculating thermodynamic quantities. Although statistical thermodynamics comprises an essential part of the college training of a chemist, its treatment in general physical chem­ istry texts is, of necessity, compressed to the point where the less competent student is unable to appreciate or comprehend its logic and beauty, and is reduced to memorizing a series of formulas.

Three years have passed after the First Moscow Seminar on Quantum Gravity. It is a rather long time interval for the modern theoretical physics. The talks given at the present Second Seminar which took place in October 13-15, 1981 in Moscow contain the discussion of new results obtained during this period and the problems which arose. More than one hundred Soviet scientists and a number of the foreign guests attended this Seminar, which as the previous one was held by the Nuclear Physics Department of the Academy of Sciences of the USSR and the Institute for Nuclear Research of the Academy of Sciences of the USSR.
