    Why trust a theory? Some further remarks (part 1). Joseph Polchinski1 Kavli Institute for Theoretical Physics University of California Santa Barbara, CA 93106-4030 USA Abstract I expand on some ideas from my recent review \String theory to the rescue." I discuss my use of Bayesian reasoning. I argue that it can be useful but that it is very far from the central point of the discussion. I then review my own personal history with the multiverse.

Reconsidering Scientific Methodology in Light of Mod- ern Physics," which took place at the Ludwig Maximilian University Munich, Dec. 7-9 2015, was for me a great opportunity to think in a broad way about where we stand in the search for a theory of fundamental physics. My thoughts are now posted at [1]. In this followup discussion I have two goals. The first is to expand on some of the ideas for the first talk, and also to emphasize some aspects of the discussion that I believe need more attention. As the only scientific representative of the multiverse at that meeting, a major goal for me was to explain why I believe with a fairly high degree of probability that this is the nature of our universe.

  • String Theory: an Evaluation
    String Theory: An Evaluation Peter Woit Department of Mathematics, Columbia University January 29, 2001 For nearly seventeen years now most speculative and mathematical work in particle theory has centered around the idea of replacing quantum field theory with something that used to be known as \Superstring Theory", but now goes under the name \M-Theory". We've been told that \string theory is a part of twenty-first-century physics that fell by chance into the twentieth century", so this year the time has perhaps finally come to begin to evaluate the success or failure of this new way of thinking about particle physics. This article will attempt to do so from the perspective of a quantum field theorist now working in the mathematical community. The theory has been spectacularly successful on one front, that of public relations. Best-selling books and web sites are devoted to explaining the subject to the widest possible audience. The NSF is funding a series of NOVA programs on string theory, and the ITP at Santa Barbara is organizing a conference to train high school teachers in string theory so that they can teach it to their students. The newspaper of record informs us that \Physicists Finally Find a Way to Test Superstring Theory" (NYT 4/4/00). The strongest scientific argument in favor of string theory is that it ap- pears to contain a theory of gravity embedded within it. It is not often mentioned that this is not yet a consistent quantum theory of gravity. All that exists at the moment is a divergent series that is conjectured to be an asymptotic perturbation series for some as yet undefined non-perturbative string theory (the terms in the series are conjectured to be finite, unlike the situation in the standard quantization of general relativity).

    CORE Metadata, citation and similar papers at core.ac.uk Provided by Open Research Exeter Esoteric Quantization The Esoteric Imagination in David Bohm’s Interpretation of Quantum Mechanics Thesis submitted to the University of Exeter by Gustavo Orlando Fernandez towards the degree of Doctor of Philosophy in Western Esotericism January 2016 This thesis is available for Library use on the understanding that it is copyright material and that no quotation from the thesis may be published without proper acknowledgement. I certify that all material in this thesis which is not my own work has been identified and that no material has previously been submitted and approved for the award of a degree by this or any other University. 1 Abstract This thesis aims to explore the relationship between the science, the philosophy and the esoteric imagination of the American physicist David Bohm (1917-1992). Bohm is recognized as one of the most brilliant physicists of his gen- eration. He is famous for his ‘hidden variables’ interpretation of quantum mechanics. Bohm wrote extensively on philosophical and psychological subjects. In his celebrated book Wholeness and the Implicate Order (1882) he introduced the influential ideas of the Explicate and the Implicate orders that are at the core of his process philosophy. Bohm was also a very close disciple of the Indian teacher Jiddu Krishnamurti (1895-1986), whom he recognized to have had an important influence on his thought. Chapter 1 is a general explanation of what I intend to do, why my re- search is filling an important gap, introduce the field of Western esoteri- cism as a scholarly subject and suggesting that it offers a fruitful way of approaching the thought of David Bohm.

  • The Trouble with Spacetime
    The Trouble with Spacetime: The Rise of the Planck Length, The Fall of a System of Theory, and What Comes Next Abstract In ancient times, the incommensurability of discrete numbers, and continuous physical magnitudes, destroyed the Pythagorean cult. Now, in modern times, the incompatibility of the discrete theory of matter, and the continuous theory of spacetime, vexes, if not threatens, the theoretical community with a similar fate. With the rise of string theory, hopes of reconciling quantum physics with continuous physics arose, only to inflate into a Landscape of near infinite possibilities and, with that, the prospect of describing the physical laws of a unique, predictable, universe, diminished significantly. Even worse, our very notion of space now appears to “evaporate,” at the Planck length, leading to the conclusion that both space and time, as we know them today, are “doomed,” as fundamental entities of theoretical physics. Since no one yet knows how to do physics without time, we reexamine Einstein’s notion of spacetime, specifically the dimension of time in spacetime, in the light of an old algebra, once proposed, as the basis for the science of pure time. The most relevant message of Lee Smolin’s book1 is not the alleged failure of string theory, but the fundamental crisis in theoretical physics, which the pursuit of string theory seems to have only exacerbated. Smolin and others, like Peter Woit, author of another anti-string theory book2 are worried that, based on ideas coming from string theory research, physicists are abandoning hope that a unique, unified, solution to fundamental challenges in theoretical physics actually exists.

March 2007 3 / 43 Introduction and Excuses What This Talk Is Not About “String Theory” includes many areas I won’t discuss, including: AdS/QCD AdS/CFT duality may lead to a string theory dual to QCD. This idea is highly testable, should reproduce QCD calculations. Test of an equivalence of two theories, not an experimental test. Quark-gluon plasma in QCD may be sufficiently similar to that in N=4 Super Yang-Mills to allow AdS/CFT to be used to make qualitative predictions about phenomena in heavy-ion collisions, where accurate QCD predictions are not available.
