On Identifying Background-Structure in Classical Field Theories
background-structure background-independence geometric objects absolute objects space-time structures Newton Einstein Newtonian mechanics Newtonian gravitation general relativity classical field theories action-reaction principle Trautman-Anderson-Friedman programme
2016/6/15
I examine a property of theories called ‘background-independence’ that Einsteinian gravitation is thought to exemplify. This concept has figured in the work of Rovelli (2001; 2004), Smolin (2006), Giu...
Operational understanding of the covariance of classical electrodynamics
Operationalism Covariance of Classical Electrodynamics Empirical Verification Transformation Rule Maxwell–Lorentz Equations
2016/6/13
It is common in the literature on classical electrodynamics and relativity theory that the transformation rules for the basic electrodynamic quantities are derived from the pre-assumption that the equ...
On the Structure of Classical Mechanics
classical mechanics structure Lagrangian mechanics Hamiltonian mechanics statespace
2016/6/12
Jill North (North, 2009) has recently argued that Hamiltonian mechanics ascribes less structure to the world than Lagrangian mechanics does. I will argue that North's argument is not sound. In doing s...
Inertial motion,explanation,and the foundations of classical spacetime theories
Inertial motion geodesic principle general relativity Newton-Cartan theory geometrized Newtonian gravitation explanation puzzle-ball view
2016/5/31
I begin by reviewing some recent work on the status of the geodesic principle in general relativity and the geometrized formulation of Newtonian gravitation. I then turn to the question of whether eit...
Evidence for the Deterministic or the Indeterministic Description?--A Critique of the Literature about Classical Dynamical Systems
determinism indeterminism randomness underdetermination ergodic theory stochatic processes dynamical systems
2016/5/31
It can be shown that certain kinds of classical deterministic descriptions and indeterministic descriptions are observationally equivalent. In these cases there is a choice between deterministic and i...
The fundamental arrow of time in classical cosmology
Time Asymmetries Cosmology Cosmological Time Arrow
2016/5/31
The aim of this paper is to show that a new understanding of fundamentality (section 2), can be applied successfully in classical cosmology and is able to improve a fundamental understanding of cosmol...
The Classical Continuum without Points
continuum punctiform non-punctiform decomposable indecomposable real numbers classical analysis
2016/5/30
We develop a point-free construction of the classical one- dimensional continuum, with an interval structure based on mereology and either a weak set theory or logic of plural quantification. In some ...
How Classical Particles Emerge from the Quantum World
Identical particles quantum particles classical particles emergence
2016/5/30
The symmetrization postulates of quantum mechanics (symmetry for bosons, antisymmetry for fermions) are usually taken to entail that quantum particles of the same kind (e.g., electrons) are all in exa...
Classical Mechanics Is Lagrangian; It Is Not Hamiltonian; The Semantics of Physical Theory Is Not Semantical
classical mechanics Lagrangian mechanics Hamiltonian mechanics
2009/11/18
One can (for the most part) formulate a model of a classical system
in either the Lagrangian or the Hamiltonian framework. Though it is
often thought that those two formulations are equivalent in al...
Nonseparability, Classical and Quantum
Electromagnetism holonomy gauge theories separability
2009/9/17
This paper examines the implications of the holonomy interpretation of classical electromagnetism. As has been argued by Richard Healey and Gordon Belot, classical electromagnetism on this interpretat...
On the problem of emergence of classical space-time: The quantum-mechanical approach
Emergence generalized functions Hilbert space
2008/4/22
The classical space-time structure is derived from the structure of an abstract infinite dimensional separable Hilbert space S. For this S is first realized as a Hilbert space H* of functions of abstr...
On Symmetry and Conserved Quantities in Classical Mechanics
classical mechanics symmetry conserved quantities
2008/4/22
This paper expounds the relations between continuous symmetries and conserved quantities, i.e. Noether's ``first theorem'', in both the Lagrangian and Hamiltonian frameworks for classical mechanics. T...
This paper expounds the modern theory of symplectic reduction in finite-dimensional Hamiltonian mechanics. This theory generalizes the well-known connection between continuous symmetries and conserved...
Platonism in classical logic versus formalism in the proposed non-Aristotelian finitary logic
foundations of mathematics foundations of quantum mechanics
2008/4/22
The main thesis of this paper is that Platonism is inherent in classical infinitary reasoning and that strict formalism inevitably leads one to the author's non-Aristotelian finitary logic (NAFL) prop...
