On the Common Structure of Bohmian Mechanics and the Ghirardi-Rimini-Weber Theory
quantum theory without observers Bohmian mechanics
2008/4/22
Bohmian mechanics and the Ghirardi-Rimini-Weber theory provide opposite resolutions of the quantum measurement problem: the former postulates additional variables (the particle positions) besides the ...
On the Property Structure of Realist Collapse of Quantum Mechanics and the So-Called "Counting Anomaly"
counting anomaly properies in quantum mechanics
2008/4/22
The aim of this paper is two-fold. Recently, Lewis has presented an argument, now known as the `counting anomaly', that the spontaneous localization approach to quantum mechanics, suggested by Ghirard...
Passage of Time in a Planck Scale Rooted Local Inertial Structure
Flow of time Temporal Transience
2008/4/22
It is argued that the `problem of time' in quantum gravity necessitates a refinement of thelocal inertial structure of the world, demanding a replacement of the usual Minkowski lineelement by a 4+2n d...
Realism about Structure: The Semantic View and Non-linguistic Representations
Realism structure representation Newman
2008/4/22
The central concern of this paper is whether the Semantic Approach to theories has the resources to appropriately capture the core tenets of structural realism. Chakravartty, for example, has argued t...
Spacetime and Structure: Structural Realism, Neo-Kantianism Idealism, or Relativized A Priorism?
spacetime structural realism structuralism
2008/4/21
The essay examines the relationship, within spacetime theories, between contemporary structural realism, Cassirer’s neo-Kantian structuralism, and Friedman’s defense of the relativized a priori. Despi...
General relativity is commonly thought to imply the existence of a unique metric structure for space-time. A simple example is presented of a general relativistic theory with ambiguous metric structur...
On December 9, 1908 Max Planck addressed the Student Corps of the Faculty of Natural Sciences of the University of Leiden. His announced topic was The Unity of the Physical World-Picture , but...
Symmetry, Structure and the Constitution of Objects
permutation symmetry structuralism structural realism
2008/4/21
In this paper I focus on the impact on structuralism of the quantum treatment of objects in terms of symmetry groups and, in particular, on the question as to how we might eliminate, or better, reconc...
The purpose of this paper is to review, clarify, and critically analyse modern mathematical cosmology. The emphasis is upon the mathematical structures involved, rather than numerical computations. Th...
In this paper I wish to make some headway on understanding what \emph{kind} of problem the ``problem of time'' is, and offer a possible resolution---or, rather, a new way of understanding an old resol...
Topological Phase Fields, Baecklund Transformations, and Fine Structure
pseudosphere phase berry Gordon
2008/4/21
Quantum coupling is defined by comparing the evolution of an input
to an output phase, where the phase is evolving on a curved
pseudospherical surface. The difference given by interference
obeys a ...
Model, Theory, and Evidence in the Discovery of the DNA Structure
DNA structure model-building phenomenologically-driven view
2008/4/15
In this paper I discuss the discovery of the DNA structure by Francis Crick and James Watson, which has provoked a large historical literature but has yet not found entry into philosophical debates. I...
Josephson Effect, Bäcklund Transformations, and Fine Structure Coupling
nonlocal nonabelian toroidally torus
2008/4/15
It is shown, that the geometric phase evolution within M
circularly and toroidally arranged virtual Josephson junctions
(coupled discrete impedance system) can be described by the
integrable case o...
Berry's phase carries physical information coded as topological
and geometrical objects that can be directly verified in
measurements. In some cases the situation can be reduced to an
irrational ph...
I address the problem of indefiniteness in quantum mechanics: the problem that the theory, without changes to its formalism, seems to predict that macroscopic quantities have no definite values. The E...
