Quantum mechanics, ontology, and non-reflexive logics

Por • 15 feb, 2018 • Category: Ambiente

This is a general philosophical paper where I overview some of my ideas concerning the non-reflexive foundations of quantum mechanics (NRFQM). By NRFQM I mean an interpretation of QM that considers an involved ontology of non-individuals as explained in the text. Thus, I do not endorse a purely instrumentalist view of QM, but believe that it speaks of something, and then I try to show that one of the plausible views of this textit{something} is as entities devoid of identity conditions.

Space and Time in Loop Quantum Gravity

Quantum gravity is expected to require modifications of the notions of space and time. I discuss and clarify how this happens in Loop Quantum Gravity.

Revelation and Reflection on Mankind by Modern Physics—Part I

Por • 5 feb, 2018 • Category: Ambiente

Confronted to unlimited three-dimensional spaces and possible higher-dimensional spaces, a hypothetical thinking is proposed in this paper by applying the basic form of dialectics, through physics, theology and many other field of studies, to advocate mankind to abandon internal conflicts in order to form a united planetary civilization.

¿Hacia una globalización con características chinas?

Por • 28 ene, 2018 • Category: Ambiente

El abanderamiento de la globalización por parte de China oculta, en realidad, un muy poderoso nacionalismo económico. Internamente, en Beijing preocupa naturalmente la estabilidad social y le interesa proteger su industria y su nivel de empleo. Por eso, Beijing toma medidas para mejorar la competitividad exportadora de las empresas y alarga su gama tecnológica, incluyendo, según sus rivales occidentales, una estrategia de captación de secretos industriales que levanta ampollas. La protección del mercado interno –incluido el laboral-, que abre a la inversión extranjera de manera cuidadosa y progresiva, mientras en el exterior promueve a sus grupos industriales constituye un inapelable éxito singular del PCCh.

A Tableaux Calculus for Reducing Proof Size

Por • 22 ene, 2018 • Category: Ambiente

A tableau calculus is proposed, based on a compressed representation of clauses, where literals sharing a similar shape may be merged. The inferences applied on these literals are fused when possible, which reduces the size of the proof. It is shown that the obtained proof procedure is sound, refutationally complete and allows to reduce the size of the tableau by an exponential factor. The approach is compatible with all usual refinements of tableaux.

Vagueness: A Conceptual Spaces Approach

Por • 14 ene, 2018 • Category: Ambiente

The conceptual spaces approach has recently emerged as a novel account of concepts. Its guiding idea is that concepts can be represented geometrically, by means of metrical spaces. While it is generally recognized that many of our concepts are vague, the question of how to model vagueness in the conceptual spaces approach has not been addressed so far, even though the answer is far from straightforward. The present paper aims to fill this lacuna.

Plato’s cave and differential forms

Por • 9 ene, 2018 • Category: Ambiente

In the 1970s and again in the 1990s, Gromov gave a number of theorems and conjectures motivated by the notion that the real homotopy theory of compact manifolds and simplicial complexes influences the geometry of maps between them. The main technical result of this paper supports this intuition: we show that maps of differential algebras are closely shadowed, in a technical sense, by maps between the corresponding spaces. As a concrete application, we prove the following conjecture of Gromov: if X and Y are finite complexes with Y simply connected, then there are constants C(X,Y) and p(X,Y) such that any two homotopic L -Lipschitz maps have a C(L+1) p -Lipschitz homotopy (and if one of the maps is a constant, p can be taken to be 2 .) We hope that it will lead more generally to a better understanding of the space of maps from X to Y in this setting.

Technological Unemployment, AI, and Workplace Standardization: The Convergence Argument

Por • 5 ene, 2018 • Category: Ambiente

The current debate over technological unemployment sacrifices significant analytic value because it is one-sided, limited in scope, and sequential. We show that analyzing technological innovations in parallel with apparently independent socio-economic innovations and trendsoffers important analytical benefits. Our focus is on socio-economic innovations and trends that standardize education, workplace requirements, and culture. A highly standardized workplace is not only more suitable for international outsourcing; it is also more suitable for machine labor. In this context, we identify five specific research questions that would benefit from parallel analysis and scenarios. We also introduce the concepts “functional equivalency” and “functional singularity” (in juxtaposition to technological singularity) to provide semantic tools that emphasize the importance of an integrated approach, capable of tracking and analyzing two interacting and potentially converging trends.

Towards Collaborative Conceptual Exploration

Por • 1 ene, 2018 • Category: Ambiente

In domains with high knowledge distribution a natural objective is to create principle foundations for collaborative interactive learning environments. We present a first mathematical characterization of a collaborative learning group, a consortium, based on closure systems of attribute sets and the well-known attribute exploration algorithm from formal concept analysis. To this end, we introduce (weak) local experts for subdomains of a given knowledge domain. These entities are able to refute and potentially accept a given (implicational) query for some closure system that is a restriction of the whole domain. On this we build up a consortial expert and show first insights about the ability of such an expert to answer queries. Furthermore, we depict techniques on how to cope with falsely accepted implications and on combining counterexamples. Using notions from combinatorial design theory we further expand those insights as far as providing first results on the decidability problem if a given consortium is able to explore some target domain. Applications in conceptual knowledge acquisition as well as in collaborative interactive ontology learning are at hand.

The Potential Impact of Quantum Computers on Society

Por • 25 dic, 2017 • Category: Ambiente

This paper considers the potential impact that the nascent technology of quantum computing may have on society. It focuses on three areas: cryptography, optimization, and simulation of quantum systems. We will also discuss some ethical aspects of these developments, and ways to mitigate the risks.
