Model Uncertainty and Policy Choice:A Plea for Integrated Subjectivism
models decision theory subjectivism climate science economics policy
2016/6/13
A question at the intersection of scientific modeling and public choice is how to deal with uncertainty about model predictions. This "high-level" uncertainty is necessarily value-laden, and thus must...
Some historical aspects concerning the rise of the first exact measurements of the anomalous magnetic moment of the muon
magnetic moment muon QED
2016/6/13
In this paper, we wish to outline the main historical moments which have led to the first exact measurements of the anomalous magnetic moment of the muon.
Did Perrin's experiments convert Poincaré to Scientific Realism?
Atomism Fundamentalism Henri Poincare Scientific Realism Structural Realism
2016/6/13
In this paper I argue that Poincaré’s acceptance of the atom does not indicate a shift from instrumentalism to scientific realism. I examine the implications of Poincaré’s acceptance of the existence ...
Mere Deviation,Critically Assessing Prenatal Testing
prenatal testing disability genetics genetic determinism selection
2016/6/13
This paper calls fresh attention to ethical problems surrounding prenatal testing by focusing on genetic knowledge gained through evolving testing procedures. Advances in reproductive and prenatal gen...
Physical Determination of the Action
relativity foundations of dynamics measurement abstraction quantification energy momentum mass fundamental equation
2016/6/13
Physical theories ought to be built up from colloquial notions such as 'long bodies', 'energetic sources' etc. in terms of which one can define pre-theoretic ordering relations such as 'longer than', ...
I offer an account of how the quantum theory we have helps us explain the enormous variety of phenomena it is generally taken to explain. The account depends on what I have elsewhere called a pragmati...
Causality and Chance in Relativistic Quantum Field Theories
Local causality Microcausality Bell correlations Relativistic quantum field theories Pragmatist interpretation Causal intervention
2016/6/13
Bell appealed to the theory of relativity in formulating his principle of local causality. But he maintained that quantum field theories do not conform to that principle, even when their field equatio...
Observation and Quantum Objectivity
Objectivity quantum theory Wigner's friend quantum Darwinism
2016/6/13
The paradox of Wigner's friend challenges the objectivity of quantum theory. A pragmatist interpretation can meet this challenge by judicious appeal to decoherence. Quantum theory provides situated ag...
On the nucleon paradigm:the nucleons are closer to reality than the protons and neutrons
Reality of physical theory distinguishing identical particles exclusion principle and spatial separation
2016/6/13
There is a widespread delusion that in theoretical nuclear physics protons and neutrons are the real thing, and nucleons are not more than a mathematically equivalent formality. It is shown that, on t...
Mathematical Representation:Playing a Role
Mathematical Structuralism Representation Modelling Van Fraassen
2016/6/13
The primary justification for mathematical structuralism is its capacity to explain two observations about mathematical objects, typically natural numbers. Non-eliminative structuralism attributes the...
Logic,Geometry And Probability Theory
quantum logic-lattice theory-geometry of quantum mechanics-quantum probability
2016/6/13
We discuss the relationship between logic, geometry and probability theory under the light of a novel approach to quantum probabilities which generalizes the method developed by R. T. Cox to the quant...
Matter or geometry as fundamental in relativity theory:How not to teach special relativity
relativity spacetime ontology constructivism
2016/6/13
In this paper, I review a number of interpretational frameworks for relativistic phenomena like length contraction and relativity of simultaneity. Of central focus is the book Physical Relativity by H...
Hypothetical Entities and Realistic Interpretation:The Case of the Muriatic Radical
Scientific Realism Reference Theoretical Terms History of Chemistry Philosophy of Chemistry Hypothetical Entities
2016/6/13
Scientific realists are committed to the claim that scientific discourse should be interpreted realistically, so that theoretical terms are understood as putatively referring expressions that have put...
Weak Discernibility For Quanta,The Right Way
Identical particles Leibniz the principle of the identity of indiscernibles quantum mechanics
2016/6/13
Muller and Saunders purport to demonstrate that, surprisingly, bosons and fermions are discernible; this paper disputes their arguments, then derives a similar conclusion in a more satisfactory fashio...
The emergence of spacetime in quantum theories of gravity

2016/6/13
This is the introduction to the special issue of Studies in the History and Philosophy of Modern Physics on the emergence of spacetime in quantum theories of spacetime.
