Are Gauge Symmetry Transformations Observable?
In a recent paper in this journal, Kosso ([2000]) discussed the observational status of continuous symmetries of physics. While we are in broad agreement with his approach, we disagree with hisExpand

Which symmetry? Noether, Weyl, and conservation of electric charge
Abstract In 1918, Emmy Noether published a (now famous) theorem establishing a general connection between continuous ‘global’ symmetries and conserved quantities. In fact, Noether's paper containsExpand

Symmetries and invariances in classical physics
Symmetry, intended as invariance with respect to a transformation (more precisely, with respect to a transformation group), has acquired more and more importance in modern physics. This ChapterExpand

General covariance from the perspective of noether's theorems
Analysis of Emmy Noether's 1918 theorems provides an illuminating method for testing the consequences of coordinate generality, and for exploring what else must be added to this requirement in orderExpand

Noether's theorems and gauge symmetries
Consideration of the Noether variational problem for any theory whose action is invariant under global and/or local gauge transformations leads to three distinct theorems. These include the familiarExpand

Epistemic Structural Realism and Poincaré’s Philosophy of Science
Recent discussions of structuralist approaches to scientific theories have stemmed primarily from John Worrall’s “Structural Realism” in which he defends a position (since characterized “epistemicExpand

The Semantic View of Theories , Scientific Structuralism and Structural Realism A Minimal Construal of Scientific Structuralism
The focus of this paper is the recent revival of interest in structuralist approaches to science and, in particular, the structural realist position in philosophy of science. The challenge facingExpand

All alone in the Universe: Individuals in Descartes and Newton
In this paper we argue that the primary issue in Descartes' Principles of Philosophy, Part II, articles 1-40, is the problem of individuating bodies. We demonstrate that Descartes departs from theExpand

DRAFT : 10 May 2011 1 Unity and change in Newton ’ s physics
Here is a problem at the heart of the metaphysics of the natural world: How, if at all, can a unity undergo change? This problem incorporates two questions. First, in virtue of what is a thing aExpand
