Our understanding of galaxies has advanced significantly in recent years. New observations from ground- and space-based telescopes, the discovery of dark matter, and powerful computer simulations have been instrumental in this. This textbook provides graduate students with a complete and thorough introduction to galactic dynamics. The first two parts of the book define the astrophysical problems and the methods for building sound physical models. Next, the observational properties and models of spiral then elliptical galaxies are examined in detail. Finally, a selection of exciting topics from contemporary research are introduced, including the formation and evolution of galaxies, cooling flows, accretion disks, and galaxies at high redshift. Throughout, the emphasis is on developing a clear understanding and good physical intuition of the processes involved. Full derivations are provided for key results and helpful problems are included. This textbook provides graduate students with a self-contained and accessible introduction to modern galactic dynamics.
How does it happen that billions of stars can cooperate to produce the beautiful spirals that characterize so many galaxies, including ours? This book presents a theory of spiral structure that has been developed over the past three decades under the continuous stimulus of new observational studies. The theory unfolds in a way that can be grasped by any reader with an undergraduate science background who is interested in astronomy, as well as by graduate students and scientists actively involved in astronomy or related subjects who want to see the "backbone" and the physical content of the theory. The foundations of this theoretical framework were laid in the early 1960s, following the pioneering work of B. Lindblad. C. C. Lin had already contributed significantly to the field of fluid mechanics when he turned his attention to spiral structures, and he has focused on the problem ever since. Giuseppe Bertin joined this research effort when he first visited at MIT in 1975, bringing to the project knowledge from his work on elliptical galaxies and plasma astrophysics. Together, Bertin and Lin have contributed to the exciting developments on spiral structure of the last few decades, working closely with many observers and other theorists. In this book they describe the density-wave theory with the goal of making the key concepts and astrophysical implications explicit and accessible. The essence of the solution Bertin and Lin present is that the spirals are wave rather than material phenomena and generally trace intrinsic characteristics of the individual galaxies. The book is in three parts--Physical Concepts, Observational Studies, and Dynamical Mechanisms--with most of the technical details confined to the last part.
This concise introduction to modern astrophysics focuses on galaxy dynamics and the discovery of dark matter halos in galaxies. Aimed at advanced undergraduates in physics, it provides an excellent bridge to important research topics in contemporary astrophysics.
This timely book critically examines the European Social Model as a contested concept and concrete set of European welfare and governance arrangements. It offers a theoretical and empirical analysis of new economic models and existing European investment strategies to address key issues within post-Covid-19 Europe.
The formulation of Maxwell’s equations completely defines the connection between the electric field and the magnetic field, definitively unifying electricity and magnetism and at the same time providing a theoretical synthesis of all the experimental phenomena connected to these areas. In his revolutionary 1864 memoir where J.C. Maxwell presented his equations, he cites a handful of scientists, which were at the basis of his Theory. This book, in its first part, presents an insight on all these latter scientists, reconstructing the scientific network behind Maxwell’s unification and, in the second part, focuses on the Italians in such a network: Ottaviano Fabrizio Mossotti and Riccardo Felici, with a further insight on the connections between Maxwell and Italy and, in particular, Tuscany.

This lecture covers several core issues in user-centered data management, including how to design usable interfaces that suitably support database tasks, and relevant approaches to visual querying, information visualization, and visual data mining. Novel interaction paradigms, e.g., mobile and interfaces that go beyond the visual dimension, are also discussed. Table of Contents: Why User-Centered / The Early Days: Visual Query Systems / Beyond Querying / More Advanced Applications / Non-Visual Interfaces / Conclusions
Written by one of the world’s renowned Bionian Field Theory scholars, this foundational volume provides a thorough introduction to all facets of psychoanalytic field theory, one of the most lively and original currents of thought in contemporary psychoanalysis, to offer new answers to age-old questions around how psychic change occurs. With clinical examples to illuminate key themes of therapeutic effectiveness, current controversies, and future developments, the book presents a radically intersubjective view of the analytic process that focuses on the plane of unconscious communication common to both analyst and patient, moving beyond the I/you division to access the shared substance of the psyche. It centers the unconscious not as a hellish region of the psyche but as an important function of the personality that gives meaning to emotional experience. Offering clear expositions of complex concepts and linking to more detailed sources of information, this book is important reading for all clinicians, trainees, and students interested in contemporary psychoanalysis.

Chroniques d’un désastre annoncé En août 1904, au cours de la Guerre russo-japonaise, les troupes japonaises font le siège de Port-Arthur et les navires russes de l’escadre du Pacifique sont bloqués dans le port. Les russes décident alors d’envoyer une seconde flotte en soutien. Mais elle doit venir de la Baltique. Un long périple de près de huit mois. Quand enfin les proues des navires russes fendent les eaux au large de la Corée, il est trop tard, Port Arthur a capitulé. Les Russes décident alors de rejoindre le port de Vladivostok. Malheureusement, ils sont repérés par la flotte japonaise, plus expérimentée et mieux équipée... Défaite catastrophique pour la flotte russe qui perdra la quasi-totalité de ses navires, la bataille de Tsushima a eu, en plus de porter atteinte au prestige international de l’Empire russe, des conséquences sur la conception des vaisseaux de guerre futurs.
