It is widely recognized that ‘global’ symmetries, such as the boost invariance of classical mechanics and special relativity, can give rise to direct empirical counterparts such as the Galileo-ship…

What ontology does realism about the quantum state suggest? The main extant view in contemporary philosophy of physics is wave-function realism. We elaborate the sense in which wave-function realism…
Branching and Uncertainty

- 1 September 2008
This paper argues that there is a simple and natural semantics under which ordinary sentences uttered in branching worlds have much the same truth values as they conventionally have in diverging worlds, and the ‘incoherence problem’ of the Everett interpretation, that it can give no meaning to the notion of uncertainty, is solved.
In Defence of Naiveté: The Conceptual Status of Lagrangian Quantum Field Theory
- D. Wallace
- PhysicsSynthese
- 1 July 2006
The analysis covers renormalisation and infinities, inequivalent representations, and the concept of localised states; the conclusion is that Lagrangian QFT is a perfectly respectable physical theory, albeit somewhat different in certain respects from most of those studied in foundational work.

The Logic of the Past Hypothesis

I attempt to get as clear as possible on the chain of reasoning by which irreversible macrodynamics is derivable from time-reversible microphysics, and in particular to clarify just what kinds of…
