“The Underdetermination of Field Theoretic Structure“
Michael Miller, University of Pittsburgh
It has been suggested that quantum field theory suffers from an underdetermination problem because there exist multiple formalisms for capturing its content. In this talk I undermine this position by indicating a sense in which the formalisms can be viewed as partially intertranslatable. However, attention to the relations between the different formalisms reveals that there is a genuine sense in which field theoretic structure is underdetermined. The talk concludes by assessing how the form of underdetermination that does obtain affects the project of interpreting the theory.

Robert Wright, Visiting Professor of Science and Religion at Union Theological Seminary, interrogates prominent physicist and ‘new atheist’ Lawrence Krauss on the origins of the universe, quantum weirdness, and the limits of scientific knowledge.
LAWRENCE KRAUSS is director of the Origins Project and Professor of Physics at Arizona State University. He has won numerous international awards and is the only physicist to have received the top awards from all three U.S. Physics Societies. He is the author of over 300 scientific publications and is also the author of 9 books including bestsellers The Physics of Star Trek and A Universe from Nothing: Why There is Something Rather than Nothing. Krauss has recently delved into the film world as executive producer and subject of The Unbelievers, a documentary film that discusses science and reason. He has dedicated his time, throughout his career, to issues of science and society and has helped spearhead national efforts to educate the public about science, ensure sound public policy, and defend science against attacks at a variety of levels. In 2015 Krauss was named Humanist of the Year.
ROBERT WRIGHT is the author, most recently, of The Evolution of God, which was a New York Times bestseller and a finalist for the Pulitzer Prize. His other books include The Moral Animal, which The New York Times Book Review named one of the ten best books of 1994, and Nonzero, which Bill Clinton called “astonishing” and instructed White House staff members to read. In 2009 Wright was named by Foreign Policy magazine as one of the top 100 global thinkers. Wright has written for The Atlantic, The New Yorker, The New York Times Magazine, Foreign Policy, and the op-ed pages of The New York Times, The Washington Post, and The Financial Times. His books have been translated into more than a dozen languages, and his awards include the National Magazine Award for Essay and Criticism. Wright is Visiting Professor of Science and Religion at Union Theological Seminary in New York, and is editor-in-chief of the websites Bloggingheads.tv and MeaningofLife.tv.
This event is part of “Contentions,” an interview and debate series hosted by Robert Wright, Visiting Professor of Science and Religion at Union Theological Seminary. Through conversations with prominent intellectuals, “Contentions” examines the relationship between science and spiritual questions.
Tentative Schedule for MAPS, 2016 Spring (more details soon):
Feb 23. 4:10-6:00pm @ Columbia University. Jacob Barandes and David Kagan (Harvard). Topic: Foundations of Quantum Mechanics.
Abstract: The language of random variables makes possible a formal analogy between classical probability theory and quantum theory that better highlights their key similarities and differences. I’ll use this formulation to clarify the underlying problems that have long obstructed the development of a satisfactory interpretation of quantum theory, suggest changes in how we introduce students to quantum theory, discuss important new requirements for future work on quantum foundations, provide a helpful classification scheme for the various prominent interpretations, and motivate a novel “minimal” modal interpretation. This new interpretation is minimal in the sense that its fundamental ingredients are only those that either have clear counterparts in classical physics or are familiar from the traditional formulation of quantum theory. I’ll explain how the minimal modal interpretation provides every quantum system with both a definite ontology as well as approximate ontological dynamics ensuring the stability of that ontology through time, whether the system is closed or open and whether the system is in a pure state or in a highly entangled improper mixture. The rules governing the ontological dynamics are based on a class of newly discovered quantum conditional probabilities whose detailed properties I will discuss in depth. I’ll conclude with a summary of open questions and implications for issues of importance to the philosophy of physics.

Physicists and philosophers have occasionally advanced arguments concerning the probabilities of possible universes. Although it may seem dubious to treat the entire universe as a random event, an appealing approach to justifying and interpreting cosmological probabilities is to extrapolate successful applications of probability in physics, such as statistical mechanics, to the universe. I argue, however, that adapting successful strategies in statistical mechanics to cosmology runs aground on several serious problems. I examine in particular two cases: adding probabilities to general relativity and treating the universe as a statistical mechanical system.

as our understanding of the universe and its basic building blocks extends to shorter and shorter distances, experiments capable of probing these scales are becoming increasingly difficult to construct. Fundamental particle physics faces a potential crisis: an absence of data at the shortest possible scales. Yet remarkably, even in the absence of experimental data, the requirement of theoretical consistency puts stringent constraints on viable models of fundamental particles and their interactions. In this talk I’ll present some of these constraints and discuss their applications for cosmology, string theory and more.

UPCOMING:
Abstract: conventional wisdom holds that since the advent of the first full theories of quantum mechanics in the mid-1920s, the Copenhagen interpretation has been the default interpretation of quantum mechanics, and has enjoyed the support of a majority of physicists ever since. This is not the case. While it is indeed true that a majority of physicists have long professed that they subscribe to the Copenhagen interpretation, the plain fact of the matter is that there is no single coherent position known as the Copenhagen interpretation, nor has there ever been one. Moreover, none of the positions that go by the name “Copenhagen interpretation” do a good job of solving the measurement problem, the central interpretive problem at the heart of quantum foundations. Nor do they evade the nonlocality that is dictated by Bell’s theorem. In this talk, I will give an overview of the history of the Copenhagen interpretation from 1926 to the present, explain its multiple inconsistencies and failures, and attempt an answer at a persistent puzzle: why does the Copenhagen interpretation remain popular among physicists despite its manifest flaws and the existence of multiple superior alternatives
About the speaker: Adam Becker is the author of What is Real? The Unfinished Quest for the Meaning of Quantum Physics. He has a PhD in physics from the University of Michigan and he is the recipient of an Alfred P. Sloan Foundation Book Grant. He is currently a visiting scholar at UC Berkeley’s Office for History of Science and Technology.

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.
Abstract: TBD.
What we are hoping for is a free, open, wide-ranging and informal conversation about a number of topics that people have lately been thinking more and more about – and that seem likely to play increasingly central roles, over the next several years, in the foundations of physics. These include questions of the emergence/fundamentality of space and time, the philosophical analysis and scientific role of chance, the relationship between physics and agency, and the possibility, desirability and scientific appropriateness of a complete and fundamental theory of nature.

I argue that we do not understand gauge theory as well as we think we do, when boundaries are present. I will briefly explain the conceptual and technical issues that arise at the boundary. I will then propose a tentative resolution, which requires us to think of theories not in space-time, but in field-space.
