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 definition of a criterion of immunogenicity
Self Nonself Continuity Tolerance Immunogenicity
2008/4/22
The main objective of immunology is to establish why and when an immune response occurs, that is, to determine a criterion of immunogenicity. According to the consensus view, the proper criterion of i...
Analysis is presented of the derivation in [1] of what is popularly known as E = mc2. It is emphasized that once a relationship, describing a phenomenon in the stationary system, is known exactly and ...
On the Emergence of Time in Quantum Gravity
quantum gravity emergence quantum geometrodynamics
2008/4/22
We discuss from a philosophical perspective the way in
which the normal concept of time might be said to `emerge'
in a quantum theory of gravity. After an introduction, we
briefly discuss the notio...
Recent work in the Everett interpretation has suggested that the problem of probability can be solved by understanding probability in terms of rationality. However, there are *two* problems relating t...
On the history of the so-called Lense-Thirring effect
Lense-Thirring effect Dragging Coriolis force
2008/4/22
Some historical documents, especially the Einstein-Besso manuscript from 1913,
an extensive notebook by Hans Thirring from 1917, and a correspondence between
Thirring and Albert Einstein in the year...
A signal development in contemporary physics is the widespread use, in explanatory contexts, of highly idealized models. This paper argues that some highly idealized models in physics have genuine exp...
The purpose of this paper is to propose an extension to Lee Smolin's hypothesis that our own universe belongs to a population of universes which have evolved by natural selection. Smolin's hypothesis ...

geometric phase Berry phase Aharonov-Bohm effect
2008/4/22
This paper addresses issues surrounding the concept of geometric phase or "anholonomy". Certain physical phenomena apparently require for their explanation and understanding, reference to toplogocial/...
Falsifications of Hameroff-Penrose Orch OR Model of Consciousness and Novel Avenues for Development of Quantum Mind Theory
quantum mind consciousness Hameroff-Penrose Orch OR
2008/4/22
In this paper we try to make a clear distinction between quantum mysticism and quantum mind theory. Quackery always accompanies science especially in controversial and still under development areas an...
Finitary and Infinitary Mathematics, the Possibility of Possibilities and the Definition of Probabilities.
many-minds quantum theory finitary and infinitary mathematics
2008/4/22
Some relations between physics and finitary and infinitary mathematics are explored in the context of a many-minds interpretation of quantum theory. The analogy between mathematical ``existence'' and ...
Higher-dimensional algebra, also known as higher-dimensional category theory, is a large-scale contemporary effort to organise the contents of mathematics, that makes genuine contact with, and goes al...
Coherence, Consistency, and Cohesion: Clade Selection in Okasha and Beyond.
Cohesion Consistency Coherence
2008/4/22
Samir Okasha argues that clade selection is an incoherent concept, because the relation that constitutes clades is such that it renders parent-offspring (reproduction) relations between clades impossi...
Coordinates, observables and symmetry in relativity
Spacetime events general covariance observables
2008/4/22
We investigate the interplay and connections between symmetry properties of equations, the interpretation of coordinates, the construction of observables, and the existence of physical relativity prin...
First-Order Logic Foundation of Relativity Theories
general relativity gravitational time dilation
2008/4/22
Motivation and perspective for an exciting new research direction interconnecting logic, spacetime theory, relativity--including such revolutionary areas as black hole physics, relativistic computers,...
