The fundamental Physics of the 20th century was constructed basically from two main
theories, general relativity and quantum theory. The later allowed the construction of
the standard model which describes three of the four known fundamental interactions
in Nature, the exception being the gravity interaction. Unfortunately, general relativity
and quantum theory have not been unified into a single coherent description of
gravity in the microscopic level yet. The gravity quantization problem exists for almost
one century and the final answer is yet unknown.
The development of quantum mechanics has taken physics in a vastly new direction from that of classical physics from the very start. In fact, there continue at present to be many developments in the subject of a very fundamental nature, such as implications for the foundations of physics, physics of entanglement, geometric phases, gravity and cosmology and elementary particles as well. It is hoped the papers in this volume will provide a much needed resource for researchers with regard to current topics of research in this growing area....
Orbis Scientiae 1999 constitutes the 28th conference on High Energy Physics
and Cosmology that were begun in 1964. It has now become an institution by itself
under the aegis of which the physicists convene annually in South Florida. It created a
Belle Époque in Coral Gables. The series of Orbis Scientiae started with the participants
of highest distinction in physics of the 20th Century. After its first two decades the
conferences have been placed in the hands of younger and promising physicists....
The vacuum is fast emerging as the central structure of modern physics. This collection brings together philosophically-minded specialists who engage these issues in the context of classical gravity, quantum electrodynamics, and the grand unification program. The vacuum emerges as the synthesis of concepts of space, time, and matter; in the context of relativity and the quantum this new synthesis represents a structure of the most intricate and novel complexity.
Random matrices are widely and successfully used in physics for almost
60-70 years, beginning with the works of Wigner and Dyson. Initially proposed
to describe statistics of excited levels in complex nuclei, the Random
Matrix Theory has grown far beyond nuclear physics, and also far beyond just
level statistics. It is constantly developing into new areas of physics and mathematics,
and now constitutes a part of the general culture and curriculum of a
The concepts and methods of topology and geometry are an indispensable part
of theoretical physics today. They have led to a deeper understanding of many
crucial aspects in condensed matter physics, cosmology, gravity, and particle
physics. Moreover, several intriguing connections between only apparently disconnected
phenomena have been revealed based on these mathematical tools.
Topological and geometrical considerations will continue to play a central role
in theoretical physics.
The Committee on Gravitational Physics (CGP) was organized by the National
Research Council’s (NRC’s) Board on Physics and Astronomy (BPA) as
part of the decadal survey Physics in a New Era. The committee’s main charges
were (1) to assess the achievements in gravitational physics over the last decade
and (2) to identify the most promising opportunities for research in the next
decade and describe the resources necessary to realize those opportunities. This
report fulfills those charges.
