Emily Adlam – Spooky Action at a Temporal Distance
19th November 2020

Abstract: Since the discovery of Bell’s theorem, the physics community has come to take seriously the possibility that the universe might contain physical processes which are spatially nonlocal, but there has been no such revolution with regard to the possibility of temporally nonlocal processes. In this talk, I argue that the assumption of temporal locality is actively limiting progress in the field of quantum foundations. I investigate the origins of the assumption, arguing that it has arisen for historical and pragmatic reasons rather than good scientific ones, then explain why temporal locality is in tension with relativity and review some recent results which cast doubt on its validity.


James Read – Newtonian Equivalence Principles
21st May 2019

 Abstract: I present a unified framework for understanding equivalence principles in spacetime theories, applicable to both relativistic and Newtonian contexts. This builds on prior work by Knox (2014) and Lehmkuhl (forthcoming).

Knox, E. (2014). Newtonian spacetime structure in light of the equivalence principle. The British Journal for the Philosophy of Science65(4), 863-880.

Tushar Menon – Metaphysical Indeterminacy in Noncommutative Geometry
18th March 2021

Abstract: In this talk, I introduce a family of approaches to quantum geometry that collectively go under the name of `noncommutative geometries’ (NCGs), expressed in the formalism of spectral triples, developed by Alain Connes and collaborators. I will discuss an interesting interpretative puzzle to which spectral triples give rise: what we might call the `indeterminacy of location’ puzzle.

‘Indeterminacy of location’ applies to situations in which, for whatever reason, according to the theory, nature does not ascribe to an entity a determinate a matter of fact about its spatial location below a particular scale. The puzzle, accordingly, is to characterise this particular brand of indeterminacy and understand the consequent metaphysical commitments of NCGs regarding space. I demonstrate how we can marshal some standard metaphysical and semantic resources to solve this puzzle.

[This talk is based on work done in collaboration with Nick Huggett and Fedele Lizzi]
