Das Fach Physik ist essentieller Bestandteil der Grundausbildung für Ingenieurwissenschaftler – hier wird die Basis für das Verständnis technischer Anwendungen gelegt sowie Methoden und Strategien erarbeitet, mit denen neues technisches Wissen erlangt wird. Mit der Einführung der gestuften Stu-diengänge wird von den Studierenden jedoch erwartet, ihre Kenntnisse im Selbststudium zu vertiefen bzw. sich selbstständig Kenntnisse in neuen Themengebieten anzueignen. Diesem Trend trägt dieses Buch Rechnung: physikalische Zusammenhänge werden ausführlich hergeleitet, wobei großer Wert auf die dazu gehörigen lückenlosen Schlussfolgerungen gelegt wird. Eine klare Begrifflichkeit ist essentiell für die quantitative Beschreibung physikalischer Sachverhalte und Prozesse. Die Zweckmäßigkeit der dafür erforderlichen Physikalischen Größen wird anhand anschaulicher Beispiele demonstriert anstatt die Größen durch „von oben verordnete“ Definitionen einzuführen.Im ersten Band werden Mechanik, Thermodynamik und Schwingungen & Wellen abgehandelt, inhaltlich werden die Themen so weit ausgeführt, dass ein problemloser Anschluss an Spezialvorlesungen des Hauptstudiums möglich ist. Inhalte des zweiten Bandes sind Elektrizität & Magnetismus, Optik sowie Messungen und ihre Auswertung.

This updated revision gives a complete and topical overview on Nonconservative Stability which is essential for many areas of science and technology ranging from particles trapping in optical tweezers and dynamics of subcellular structures to dissipative and radiative instabilities in fluid mechanics, astrophysics and celestial mechanics. The author presents relevant mathematical concepts as well as rigorous stability results and numerous classical and contemporary examples from non-conservative mechanics and non-Hermitian physics. New coverage of ponderomotive magnetism, experimental detection of Ziegler's destabilization phenomenon and theory of double-diffusive instabilities in magnetohydrodynamics.

This work gives a complete overview on the subject of nonconservative stability from the modern point of view. Relevant mathematical concepts are presented, as well as rigorous stability results and numerous classical and contemporary examples from mechanics and physics. It deals with both finite- and infinite-dimensional nonconservative systems and covers the fundamentals of the theory, including such topics as Lyapunov stability and linear stability analysis, Hamiltonian and gyroscopic systems, reversible and circulatory systems, influence of structure of forces on stability, and dissipation-induced instabilities, as well as concrete physical problems, including perturbative techniques for nonself-adjoint boundary eigenvalue problems, theory of the destabilization paradox due to small damping in continuous circulatory systems, Krein-space related perturbation theory for the MHD kinematic mean field α²-dynamo, analysis of Campbell diagrams and friction-induced flutter in gyroscopic continua, non-Hermitian perturbation of Hermitian matrices with applications to optics, and magnetorotational instability and the Velikhov-Chandrasekhar paradox. The book serves present and prospective specialists providing the current state of knowledge in the actively developing field of nonconservative stability theory. Its understanding is vital for many areas of technology, ranging from such traditional ones as rotor dynamics, aeroelasticity and structural mechanics to modern problems of hydro- and magnetohydrodynamics and celestial mechanics.

Bridging lower-division physics survey courses with upper-division physics courses, Oscillations and Waves: An Introduction develops a unified mathematical theory of oscillations and waves in physical systems. Emphasizing physics over mathematics, the author includes many examples from discrete mechanical, optical, and quantum mechanical systems; continuous gases, fluids, and elastic solids; electronic circuits; and electromagnetic waves. Assuming familiarity with the laws of physics and college-level mathematics, the book focuses on oscillations and waves whose governing differential equations are linear. The author covers aspects of optics that crucially depend on the wave-like nature of light, such as wave optics. He also introduces the conventional complex representation of oscillations and waves later in the text during the discussion of quantum mechanical waves. This helps students thoroughly understand how to represent oscillations and waves in terms of regular trigonometric functions before using the more convenient, but much more abstract, complex representation. Based on the author's longstanding course at the University of Texas at Austin, this classroom-tested text helps students acquire a sound physical understanding of wave phenomena. It eases students'difficult transition between lower-division courses that mostly encompass algebraic equations and upper-division courses that rely on differential equations.

This introductory text emphasises physical principles, rather than the mathematics. Each topic begins with a discussion of the physical characteristics of the motion or system. The mathematics is kept as clear as possible, and includes elegant mathematical descriptions where possible. Designed to provide a logical development of the subject, the book is divided into two sections, vibrations followed by waves. A particular feature is the inclusion of many examples, frequently drawn from everyday life, along with more cutting-edge ones. Each chapter includes problems ranging in difficulty from simple to challenging and includes hints for solving problems. Numerous worked examples included throughout the book.Professor George C. King, Department of Physics & Astronomy, University of Manchester, Manchester, UK.

This book reviews the status of a very exciting field — neutrino oscillations — at a very important time. The fact that neutrinos have mass has only been proved in the last few years and the acceptance of that fact has opened up a whole new area of study to understand the fundamental parameters of the mixing matrix.The book summarizes the results from all the experiments which have played a role in the measurement of neutrino oscillations and briefly describes the scope of some new planned experiments. Contributions include a theoretical introduction by Stephen Parke from FNAL, as well as articles from all the major experimental groups who have been pivotal in uncovering the nature of the neutrino mass.
