Holography and Emergence
holography quantum gravity philosophy of duality theoretical equivalence AdS/CFT gauge theory
2016/6/15
In this paper, I discuss one form of the idea that spacetime and gravity might ‘emerge’ from quantum theory, i.e. via a holographic duality, and in particular via AdS/CFT duality. I begin by giving a ...
Some Remarks on Rovelli's "Why Gauge?"
philosophy of gauge theory Yang-Mills physical significance of gauge-dependence

Rovelli's "Why Gauge?" offers a parable to show that gauge-dependent quantities have a modal and relational physical significance. We subject the morals of this parable to philosophical scrutiny and a...

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...

In this article I argue that a methodological challenge to an integrated history and philosophy of science approach put forth by Ron Giere almost forty years ago can be met by what I call the Kuhnian ...
Kuhnian theory-choice,the GWS model,and the neutral current
theory-choice Glashow-Weinberg-Salam model weak neutral current theoretical virtues discovery
2016/6/15
In the Kuhnian view of theory choice, theories, as a matter of empirical fact, often score differently well with regard to the standard theoretical virtues. The case I discuss in this paper, however, ...
In a recent book and an article, Carl Craver construes the relations between different levels of a mechanism, which he also refers to as constitutive relations, by means of mutual manipulability (MM)....

The problem of unifying knowledge represents the frontier between science and philosophy. Science approaches the problem analytically bottom-up whereas, prior to the end of the nineteenth century, phi...

If it is possible to detect the path of an atom in a double-slit atom interferometer, then interference will not be observed even if path detection causes no change in the atom's momentum. This fact w...
