Leibnizian relationalism for general relativistic physics

An ontology of Leibnizian relationalism, consisting in distance relations among sparse matter points and their change only, is well recognized as a serious option in the context of classical mechanics. In this paper, we investigate how this ontology fares when it comes to general relativistic physics. Using a Humean strategy, we regard the gravitational field as a means to represent the overall change in the distance relations among point particles in a way that achieves the best combination of being simple and being informative.

Juan Arias: ¿Dónde tropezó Dilma?

Habría que preguntarse dónde acabó tropezando políticamente Dilma Rousseff, ya que existe un consenso general en cuanto a su honestidad personal. Negar que Rousseff ha cometido errores de cálculo político sería a estas alturas querer negar algunas escenas cruciales de este drama. Más allá de las luchas jurídicas, no cabe duda de que Dilma tuvo en sus manos varias opciones de abordar su defensa y de buscar la mejor salida para ella y para la sociedad, para evitar que todo esto no acabara convirtiéndose en un drama nacional más psicoanalítico que político. Podría, cuando aún había tiempo, haber convocado nuevas elecciones, dejando a los ciudadanos la posibilidad de expresarse en las urnas. Lo ha tratado de hacer ahora, cuando ya no hay ni tiempo ni voluntad en el Congreso.

Waiting for the W and the Higgs

The search for the left-handed W ± bosons, the proposed quanta of the weak interaction, and the Higgs boson, which spontaneously breaks the symmetry of unification of electromagnetic and weak interactions, has driven elementary-particle physics research from the time that I entered college to the present and has led to many unexpected and exciting discoveries which revolutionized our view of subnuclear physics over that period. In this article I describe how these searches and discoveries have intertwined with my own career.

A persistent particle ontology for QFT in terms of the Dirac sea

We show that the Bohmian approach in terms of persisting particles that move on continuous trajectories following a deterministic law can be literally applied to QFT. By means of the Dirac sea model — exemplified in the electron sector of the standard model neglecting radiation — we explain how starting from persisting particles, one is led to standard QFT employing creation and annihilation operators when tracking the dynamics with respect to a reference state, the so-called vacuum.

The changing faces of the Problem of Space in the work of Hermann Weyl

During his life Weyl approached the problem of space (PoS) from various sides. Two aspects stand out as permanent features of his different approaches: the {\em unique determination of an affine connection} (i.e., without torsion in the terminology of Cartan) and the question {\em which type of group} characterizes physical space. The first feature came up in 1919 (commentaries to Riemann’s inaugural lecture) and played a crucial role in Weyl’s work on the PoS in the early 1920s. He defended the central role of affine connections even in the light of Cartan’s more general framework of connections with torsion.

The whole game is about containing Russia-China

In many aspects, not much has changed from 24 years ago when, only three months after the dissolution of the USSR, the Pentagon’s Defense Planning Guidance proclaimed: “Our first objective is to prevent the reemergence of a new rival…This requires that we endeavor to prevent any hostile power from dominating a region whose resources would, under consolidated control, be sufficient to generate global power. These regions include Western Europe, East Asia, the territory of the former Soviet Union and southwest Asia. ” Talk about a prescient road map of what’s happening right now; the “rival”, “hostile” power is actually two powers involved in a strategic partnership: RC.

On Noncontextual, Non-Kolmogorovian Hidden Variable Theories

One implication of Bell’s theorem is that there cannot in general be hidden variable models for quantum mechanics that both are noncontextual and retain the structure of a classical probability space. Thus, some hidden variable programs aim to retain noncontextuality at the cost of using a generalization of the Kolmogorov probability axioms. We generalize a theorem of Feintzeig (2015) to show that such programs are committed to the existence of a finite null cover for some quantum mechanical experiments, i.e., a finite collection of probability zero events whose disjunction exhausts the space of experimental possibilities.

The origins of the research on the foundations of quantum mechanics (and other critical activities) in italy during the 1970s

We present a reconstruction of the studies on the Foundations of Quantum Mechanics (FQM) carried out in Italy at the turn of the 1960s. Actually, they preceded the revival of the interest of the American physicists towards the FQM around mid-1970s, recently reconstructed by David Kaiser in a book of 2011. An element common to both cases is the role played by the young generation, even though the respective motivations were quite different. In the US they reacted to research cuts after the war in Vietnam, and were inspired by the New Age mood. In Italy the dissatisfaction of the young generations was rooted in the student protests of 1968 and the subsequent labour and social fights, which challenged the role of scientists. The young generations of physicists searched for new scientific approaches and challenged their own scientific knowledge and role.

On the mathematic prediction of economic and social crises: toward a harmonic interpretation of the Kondratiev wave

In Part One of this paper we use the harmonic analogy of a musical octave to analyze mathematic ratios of U.S. real GNP. These ratios are generated by bringing together figures for U.S. real GNP over intervals of time – “spreads of years” – as numerator and denominator in a single fraction. Using a range of 7-year to 18-year “spreads,” we find that this approach provides strong evidence that American economic history is composed of four 14-year quarter-cycles within a 56 year circuit in the real GNP of the United States, 1869-2007. These periods correlate closely with analysis by Nickolai Kondratiev and provide a framework for predicting an annual steady state rate of growth for the United States falling between 3.4969% and 3.4995% per year.

El problema del tiempo en la física: un planteamiento existencial de la ciencia desde Heidegger

Este artículo se propone caracterizar el sentido propio del ejercicio científico desde nociones del pensamiento de Heidegger como la caída y la actitud teórica. En la búsqueda de una vía de acceso que permita dicha tarea, se indagará en la relación que ha tenido la física con el concepto de tiempo. Este será el punto de partida desde el cual se advertirá que su trato particular con el tiempo devela rasgos propios de su modo concreto de ocuparse con la realidad. Así, este artículo planteará cómo es que la concepción de tiempo clásica y sus reformulaciones se fundan, en última instancia, en una relación ocupada del existir que caracterizaría el quehacer científico mismo. Con ello, se realizará una elucidación de la ciencia que rinda cuenta del presente como el horizonte existencial de su despliegue fáctico.

Electoral Stability and Rigidity

Some argue that political stability is best served through a two-party system. This study refutes this. The author mathematically defines the stability and rigidity of electoral systems comprised of any quantity of electors and parties. In fact, stability is a function of the quantity of electors – i.e., the number of occupied seats at the table. As the number of electors increases, the properties of an electorate are increasingly well resolved, and well described by those of an electorate that is least excessive — that is to say an electorate that is closest to equilibrium. Further, electoral rigidity is a function of the quantity of parties and their probabilities of representation. An absolutely rigid system admits no fluctuations — whatever happens to one elector will happen to all electors.
