“Why We Can’t Have Nice Things: Metaphysics and Quantum Decoherence” 
Elise Crull (City College, CUNY)
Though the universality of entanglement has long been known to physicists, the apparent “classicality” of objects treated within traditional ontologies has prevented philosophers from taking the implications of widespread entanglement to heart.  Decoherence is a physical process resulting from entanglement that explains the appearance of a classical world despite underlying quantum dynamics.  Not only does decoherence explain whence the perception of nice, classical things in a quantum world, but it further demonstrates the impossibility of carving, jointing, or partitioning such a world in an ontologically meaningful way.

Beauty: How to Make It Safe for the 21st Century, Dominic McIver Lopes @ Lang Recital Hall, 4th flr., Hunter College
Sep 27 @ 6:00 pm

Critiques of beauty in art and in everyday life assume the traditional idea that aesthetic value is a kind of power to please. An entirely new picture comes from a close look at intricately structured networks of agents who interact with each other in aesthetic enterprises. Aesthetic values give us reasons to act in the context of social practices. The “network theory” explains why, despite the critiques, beauty never disappeared from art, why it’s as humanly important as ever, and how it can be harnessed to address pressing social problems.

Title: It matters how you slice it: relativity and causation

Abstract: I argue that if we take the standard formulation of special relativity seriously, causation is frame-dependent. Thus, many ordinary causal claims require a parameter to specify the relevant frame of reference. This is in contrast to the widely-accepted belief that the causal structure of the world is objectively and absolutely determined by the light cone structure. Any event that can affect another (so the thought goes) must do so via light or matter, and the spacetime structure will tell us which of those came first, absolutely. For instance, according to Carl Hoefer (2009, 694, italics in original), if we assume that all signals travel slower than or equal to the speed of light, “we may take the light-cone structure of Minkowski spacetime as equally representing the causal structure of spacetime.” I argue that causation in relativistic spacetime is not so simple. Events can be extended in space and time, and events can be related to one another by distance and duration. Yet, according to special relativity, extension in space and time (i.e., distances and durations) are not invariant—they depend upon relative motion. Therefore, when ordinary events enter into causal relations, they do so relative to frames of reference, which can yield different causes and different effects. If you want to keep your promises, or bring about one outcome rather than another, you should take note of your reference frame.

Title: Typical Quantum Worlds

Abstract: Hugh Everett III’s pure wave mechanics, sometimes known as the many-worlds interpretation of quantum mechanics, was proposed as a solution to the quantum measurement problem. Both physicists and philosophers of physics have repeatedly claimed to be able to deduce the standard quantum probabilities from pure wave mechanics alone. We will consider why this is impossible, then consider how Everett himself understood quantum probabilities. This will involve clearly distinguishing between typical and probable quantum worlds.

“The​ ​ Real​ ​ Difference​ ​ Between​ ​ Mental​ ​ Time​ ​ Travel​ ​ and​ ​ What-Where-When Memory” Simon Brown @ CUNY Grad Center, rm 7113
Oct 20 @ 10:30 am – 12:30 pm

PoPRocks (formerly known as ‘WoPoP’) is an ongoing series in the NYC area for early career researchers – typically grad students and postdocs – working on philosophy of psychology/mind/perception/cognitive science/neuroscience/… . We meet roughly once every 2 weeks at 10.30-12.30 on Fridays in CUNY’s Graduate Center (Room 7113) to informally discuss a draft paper by one of our members. Typically presenters send a copy of their paper around 1 week in advance, so do join the mailing list (by emailing poprocksworkshop@gmail.com or one of the organizers) or email to ask for a copy of the paper. We aim for a friendly, constructive discussion with the understanding that the drafts discussed are typically work in progress.

Questioning the Evidence for Cosmic Expansion – Elise Crull (CCNY) @ CUNY Grad Center, rm 5307
Apr 10 @ 4:00 pm – 6:00 pm
Expansion is a key feature of the standard cosmological model, yet evidence for it is not as strong as often believed. The only direct evidence is galactic red-shifting, but reasoning from these data to expansion is not straightforward. I argue that the relationship is better understood as inference to the best explanation, and granting this, that expansion is not the obvious best explanation. This is demonstrated by investigating the fitness of the ΛCDM model as against static models under various indirect tests.In this talk I shall focus on time dilation studies: if expansion is happening, then general relativity suggests that clocks in substantially red-shifted galaxies ought to run slow with respect to the local frame. I briefly discuss the potential threat of selection bias in Type Ia supernovae time dilation tests, and evaluate the research methods employed by those assessing the mysterious lack of time dilation in gamma-ray bursts and quasars.

If expansion is not the best explanation for the relevant data, then one can motivate certain normative claims about methodological shifts in contemporary cosmology. To wit—more thought should be dedicated to alternate explanations for red-shifting phenomena, and to the development and careful analysis of indirect tests for expansion as against alternative cosmological models.

Title: On Dualities and Equivalences Between Physical Theories.

Abstract: My main aim is to make a remark about the relation between (i) dualities between theories, as `duality’ is understood in physics and (ii) equivalence of theories, as `equivalence’ is understood in logic and philosophy. The remark is that in physics, two theories can be dual, and accordingly get called `the same theory’, though we interpret them as disagreeing—so that they are certainly equivalent, as `equivalent’ is normally understood. So the remark is simple: but, I shall argue, worth stressing—since often neglected.

My argument for this is based on the account of duality by De Haro and myself: which is illustrated here with several examples, from both elementary physics and string theory. Thus I argue that in some examples, including in string theory, two dual theories disagree in their claims about the world.

I also spell out how this remark implies a limitation of proposals (both traditional and recent) to understand theoretical equivalence as either logical equivalence or a weakening of it.

When Fields Are Not Degrees of Freedom, Mario Hubert (Columbia) @ CUNY Grad Center, 5307
Nov 28 @ 4:30 pm – 6:30 pm

We show that in the Maxwell–Lorentz theory of classical electrodynamics most initial values for fields and particles lead to an ill-defined dynamics, as they exhibit singularities or discontinuities along light-cones. This phenomenon suggests that the Maxwell equations and the Lorentz force law ought rather to be read as a system of delay differential equations, that is, differential equations that relate a function and its derivatives at different times. This mathematical reformulation, however, leads to physical and philosophical consequences for the ontological status of the electromagnetic field. In particular, fields cannot be taken as independent degrees of freedom, which suggests that one should not add them to the ontology.

Stages in Spacetime: The Languages of Persistence @ CUNY Grad Center, 7314
Feb 11 @ 4:15 pm – 6:15 pm

Motivated by considerations from relativity theory, philosophers have recently contended that talk about an object’s existence in time should not be taken as fundamental, but rather analysed in the language of a formal theory of location in spacetime. This suggestion has important consequences for the debate about persistence: how do ordinary objects exist at different times? It has triggered a program of recovery whereby the main views from the classical debate, previously expressed using the language of temporal mereology, have been redefined in a locational framework. In this paper, I extend this program to the stage theory of persistence, the view according to which objects are instantaneous three-dimensional stages which exist at different times by virtue of having counterparts at these times. I offer a new characterization of the view, the first in a purely locational language, and argue that this locational approach helps dissolve confusions about the view.
