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....
The aim of this introduction is to offer a brief outline of Bohr’s complementarity as an
interpretation of quantum mechanics and of the phenomena in question in it, quantum
phenomena. This outline may be seen as primarily philosophical insofar as it aims to
delineate the philosophical content of Bohr’s key concepts.
Search algorithms aim to find solutions or objects with specified properties and constraints in a large solution search space or among a collection of objects. A solution can be a set of value assignments to variables that will satisfy the constraints or a sub-structure of a given discrete structure. In addition, there are search algorithms, mostly probabilistic, that are designed for the prospective quantum computer.
Traditionally astrophysics has concerned itself with minimum time-scales measured
in hours rather than seconds. This was understandable as the available recording
media were slow; e.g. chart recorders and photographic plates. In the 1950s, 60s
and 70s wavebands away from the optical were developed; from ground based
radio studies to space and balloon borne high energy work. In contrast to optical
wavelengths instrumentation in these (high and low energy) regimes was capable
of time resolutions of less than a second....
