A conference celebrating Remo Ruffini's 80th birthday was held in Nice, France, from 16 to 18 May 2022, with the participation of over 90 scientists. Among the contributions presented orally there were those by Rashid Sunyaev, Peter Predehl, Demetrios Christodoulou, Thibault Damour, Nathalie Deruelle, Roy Kerr, Tsvi Piran, Claus Laemmerzahl, Asghar Qadir, Chen Pisin, and Marco Tavani, in the presence of Agnès Rampal, the representative of the Mayor of Nice. An extraordinary moment of the meeting in Nice was the delivery of the Marcel Grossmann Award to Rashid Sunyaev and Peter Predehl for the Spectr-Roentgen-Gamma (SRG) mission. This volume contains 10 papers by some of the meeting participants and collaborators of Remo Ruffini.

The book collects 29 papers which have been particularly influential in the development of accretion theory. As an introductory paper a recent review on the subject is reported. An extensive list of references closes the volume.
Stephen Hawking, the Lucasian Professor of Mathematics at Cambridge University, has made important theoretical contributions to gravitational theory and has played a major role in the development of cosmology and black hole physics. Hawking's early work, partly in collaboration with Roger Penrose, showed the significance of spacetime singularities for the big bang and black holes. His later work has been concerned with a deeper understanding of these two issues. The work required extensive use of the two great intellectual achievements of the first half of the Twentieth Century: general relativity and quantum mechanics; and these are reflected in the reprinted articles. Hawking's key contrib...
Notes prepared in Collaboration with Ranjeet S Tate It is now generally recognized that perturbative field theoretical methods that have been highly successful in the quantum description of non-gravitational interactions cannot be used as a means of constructing a quantum theory of gravity. The primary aim of the book is to present an up- to-date account of a non-perturbative, canonical quantization program for gravity. Many of the technical results obtained in the process are of interest also to differential geometry, classical general relativity and QCD. The program as a whole was highlighted in virtually every major conference in gravitational physics over the past three years.
Vast markets for high-symbolic-value goods serve as an expansive worldwide arena where luxury brands and products compete for consumer attention. As global luxury markets have grown and continue to grow, uncovering successful methods for maintaining brand image and consumer desire is critical to the success of high-end brands. Global Marketing Strategies for the Promotion of Luxury Goods explores the latest promotional trends, business models, and challenges within the luxury goods market. Focusing on strategies for achieving competitive advantage, new market development, as well as the role of the media in luxury brand building, this timely reference publication is designed for use by business professionals, researchers, and graduate-level students.
This book deals with the evolution of X-ray astronomy during the initial phases of its development. Three transformations of astronomy as a discipline are highlighted: the augmentation of purely optical observations; the emergence of federal funding as the dominant source of financial support; and the greatly altered size and structure of the research community.
Accretion disks in compact stellar systems containing white dwarfs, neutron stars or black holes are the principal laboratory for understanding the role of accretion disks in a wide variety of environments from proto-stars to quasars. Recent work on disk instabilities and dynamics has given a new theoretical framework with which to study accretion disks. Modeling of time-dependent phenomena provides new insight into the causes and interpretation of photometric and spectroscopic variability and new constraints on the fundamental physical problem — the origin of viscosity in accretion disks. This book contains expert reviews on the nature of limit cycle thermal instabilities and a variety of closely related topics from the theory of angular momentum transport to eclipse mapping of the disk structure. The result is a comprehensive contemporary survey of the structure and evolution of accretion disks in compact binary systems.
The past two decades have observed dramatic advancement in our understanding of the universe. Such progress in turn has triggered further questions yet to be answered. Aspired by such prospects, several institutions dedicated to the research of cosmology have been established in the last decade, which include the Leung Center for Cosmology and Particle Astrophysics (LeCosPA) at the National Taiwan University. To celebrate its 4th anniversary the First LeCosPA Symposium was held in February 2012 at NTU. Internationally renowned physicists and authorities in cosmology, particle astrophysics, gravity and general relativity, and high energy physics convened to survey our present understanding of the universe and to explore the future prospects from both theoretical and experimental perspectives. Topics covered include the detection and the nature of dark matter and dark energy, the fundamental understanding of space, time, mass and gravity itself, cosmological constant and vacuum energy, etc. This book should be valuable to researchers and students in the field of cosmology and particle astrophysics.
Lee Smolin offers a new theory of the universe that is at once elegant, comprehensive, and radically different from anything proposed before. Smolin posits that a process of self organization like that of biological evolution shapes the universe, as it develops and eventually reproduces through black holes, each of which may result in a new big bang and a new universe. Natural selection may guide the appearance of the laws of physics, favoring those universes which best reproduce. The result would be a cosmology according to which life is a natural consequence of the fundamental principles on which the universe has been built, and a science that would give us a picture of the universe in which, as the author writes, "the occurrence of novelty, indeed the perpetual birth of novelty, can be understood." Smolin is one of the leading cosmologists at work today, and he writes with an expertise and force of argument that will command attention throughout the world of physics. But it is the humanity and sharp clarity of his prose that offers access for the layperson to the mind bending space at the forefront of today's physics.
