In life and work, Claudio Bunster (formerly Teitelboim) prefers extreme challenges. Bunster, a physicist who contemplates brain-warping theories of space and time, returned to his native Chile from the United States precisely when most intellectuals would have stayed clear— during the middle of the Pinochet dictatorship (K. Mossman, Proceedings of the National Academy of Sciences) Against this backdrop, Bunster founded the Centro de Estudios Científicos (CECS), a world class institute for frontier science research in Chile. His mentor, John A. Wheeler often used Teddy Roosevelt’s advice, "Do what you can, where you are, with what you have." "I followed his advice," said Bunster. "At latitude 40°S there is a science institute where one can find the footprints of Wheeler in every corner." As a true pioneer, Bunster was ahead of his time, opening roads, pushing the frontiers, under extreme conditions, in unexplored environments. Throughout his career, black holes, monopoles, the Antarctic vastness and the entire universe, have been the objects of his fascination: extreme, simple objects where beauty is best captured and displayed. On 10 and 11 January 2008, the meeting Quantum Mechanics of Fundamental Systems: The Quest for Beauty and Simplicity –Claudio’s Fest took place in Valdivia to celebrate Claudio Bunster’s 60th birthday. This volume collects the contributions that were discussed at this meeting by many of Bunster’s colleagues and longtime collaborators. Articles by L. Brink, S. Carlip, F. Englert, S. Hawking, M. Henneaux, C.W. Misner and L. Susskind, among others, highlight the broad impact of Bunster, providing unique insightful views on many topics addressed by him in his scientific career, ranging from black holes and symmetries in gravity and supergravity, to cosmology. The meeting was co-organized by the CECS and the International Solvay Institutes.

En suivant deux fils rouges, l’histoire des grandes révolutions de la physique au xxe siècle et l’abstraction progressive du concept de symétrie, de son usage ordinaire en géométrie à son application aux lois de la physique, cette leçon inaugurale aborde un des défis majeurs de la physique actuelle, celui de réconcilier la relativité d'Einstein et la mécanique quantique, théories amplement vérifiées empiriquement et pourtant incompatibles. C’est peut-être dans une symétrie immense, décrite en théorie des groupes par des groupes très particuliers, que réside la clé pour formuler cette théorie plus fondamentale de la gravitation, qui pourrait permettre la grande synthèse avec la mécanique quantique.

Written for researchers focusing on general relativity, supergravity, and cosmology, this is a self-contained exposition of the structure of the cosmological singularity in generic solutions of the Einstein equations, and an up-to-date mathematical derivation of the theory underlying the Belinski-Khalatnikov-Lifshitz (BKL) conjecture on this field. Part I provides a comprehensive review of the theory underlying the BKL conjecture. The generic asymptotic behavior near the cosmological singularity of the gravitational field, and fields describing other kinds of matter, is explained in detail. Part II focuses on the billiard reformulation of the BKL behavior. Taking a general approach, this section does not assume any simplifying symmetry conditions and applies to theories involving a range of matter fields and space-time dimensions, including supergravities. Overall, this book will equip theoretical and mathematical physicists with the theoretical fundamentals of the Big Bang, Big Crunch, Black Hole singularities, the billiard description, and emergent mathematical structures.

Ever since 1911, the Solvay Conferences have shaped modern physics. The 23rd edition, chaired by 2004 Nobel Laureate David Gross, did not break with that tradition. It gathered most of the leading figures working on the central problem of reconciling Einstein's theory of gravity with quantum mechanics. These proceedings give a broad overview with unique insight into the most fundamental issues raised by this challenge for 21st century physics, by distinguished renowned scientists. The contributions cover: the status of quantum mechanics, spacetime singularities and breakdown of classical space

Ever since 1911, the Solvay Conferences have shaped modern physics. The 25th edition held in October 2011 in Brussels and chaired by David Gross continued this tradition and celebrated the first centennial of this illustrious series of conferences. The development and applications of quantum mechanics have always been the main threads in the history of the Solvay Conferences, hence the 25th Solvay conference gathered many of the leading figures working on a wide variety of profound problems in physics where quantum mechanical effects play a central role. The conference addressed some of the mo
