Do Quantum Objects Have Temporal Parts?
temporal parts perdurantism quantum objects time persistence
2016/6/15
This paper provides a new context for an established metaphysical debate regarding the problem of persistence. I contend that perdurance, a popular view about persistence which maintains that objects ...
From Kantian schematism to the system of experience’s invariants:the coordination of concepts and spatio-temporal objects in Cassirer’s philosophy
Cassirer Kant concept schema object causality
2016/5/31
This paper analyzes Cassirer's account of the coordination of concepts and spatio-temporal objects. We shall see that, in contradistinction to Kantian schematism, Cassirer maintains that this coordina...
Quantum Objects
Measurement problem interpretation of quantum mechanics four-dimensionalism unsharp reality Sadra Philosophy
2016/5/30
In this paper, we suggest an alternative interpretation for the quantum state vector, which, by considering temporal parts for physical objects, aims to give an intelligible account of measurement pro...
Theoretical technologies in an “experimental” setting: empirical modeling of proteinic objects and simulation of their dynamics within scientific collaborations around a supercomputer
biophysics protein chemistry models simulation experimental data
2009/9/8
This paper examines, as a case study, some modeling and simulating practices in protein chemistry. In this field, theorists try to grasp proteinic objects by constructing models of their structures an...
Species are not theoretical objects, or, On what there is in biology
theoretical objects biology
2009/9/8
It is often claimed that species are the units of evolution, but this is not defined or clearly explained. In this paper I will argue that species are phenomenal objects that stand in need of explanat...
Formal Systems as Physical Objects: A Physicalist Account of Mathematical Truth
mathematical truth physicalism formal systems deduction
2008/4/22
This paper is a brief formulation of a radical thesis. We start with the formalist doctrine that mathematical objects have no meanings; we have marks and rules governing how these marks can be combine...
Particles, Objects, and Physics
indistinguishability indiscernibility permutation symmetry
2008/4/22
This thesis analyses the ontological nature of quantum particles. In it I argue that quantum particles, despite their indistinguishability, are objects in much the same way as classical particles. Thi...
Random Witnesses and the Classical Character of Macroscopic Objects
Entanglement witnesses Macroscopic objects in quantum mechanics
2008/4/22
Why don't we see large macroscopic objects in entangled states? Even if the particles composing the object were all entangled and insulated from the environment, we shall still find it almost always i...
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 Anderson-Friedman Absolute Objects Program: Several Successes, One Difficulty
general covariance absolute object spinor density
2008/4/21
The Anderson-Friedman absolute objects project is reviewed. The Jones-Geroch dust 4-velocity counterexample is resolved by eliminating irrelevant structure. Torretti's example involving constant curva...
The Relevance of Irrelevance: Absolute Objects and the Jones-Geroch Dust Velocity Counterexample, with a Note on Spinors
absolute object general covariance dust spinor parametrized
2008/4/21
James L. Anderson analyzed the conceptual novelty of Einstein's theory of gravity as its lack of ``absolute objects.'' Michael Friedman's related concept of absolute objects has been criticized by Rog...
This is a copy of my DPhil thesis, the abstract for which is as follows:
The first third of this thesis argues for a B-theoretic conception of time according to which all times exist equally and th...
Particle indistinguishability has always been considered a purely quantum mechanical concept. In parallel, indistinguishable particles have been thought to be entities that are not properly speaking o...
Absolute Objects, Counterexamples and General Covariance
absolute object general covariance
2008/4/9
The Anderson-Friedman absolute objects program has been a favorite analysis of the substantive general covariance that supposedly characterizes Einstein's General Theory of Relativity (GTR). Absolute ...
Absolute Objects and Counterexamples: Jones-Geroch Dust, Torretti Constant Curvature, Tetrad-Spinor, and Scalar Density
absolute object general covariance
2008/4/9
James L. Anderson analyzed the novelty of Einstein's theory of gravity as its lack of "absolute objects." Michael Friedman's related work has been criticized by Roger Jones and Robert Geroch for impla...
