Until relatively recently this theory has been regarded as the foundation of modern cosmology, the branch of science devoted to the study of the Universe as a whole. I am talking now to one of the most well-known, outspoken critics of the Big Bang, the American physicist Eric J Lerner.Readers of my articles in Asia Times will know the name: Eric is also the founder and chief scientist of the company LPP Fusion, which is developing the Dense Plasma Focus, a revolutionary type of fusion reactor which could provide a shortcut toward realizing nuclear fusion as an energy source.

This new short version of my 1983 paper suggests the goals you might have for your system — Simple, Timely, Efficient, Adaptable, Dependable, Yummy (STEADY) — and techniques for achieving them — Approximate, Incremental, Divide & Conquer (AID). It also gives some principles for system design that are more than just hints, and many examples of how to apply the ideas.

Este trabajo se divide en dos partes: primero, se hace un resumen del artículo Measurement theory, procedimientos de medición fundamentales y semántica de los conceptos métricos (1) de José A. Díez Calzada, y segundo, se hacen algunos comentarios al hilo del mismo. Dichas sugerencias no pretenden desde luego constituir una crítica bien articulada ni, por supuesto, una propuesta de una concepción alternativa, sino que sólo quieren resaltar los aspectos que me han parecido más importantes o problemáticos

Crook cita un artículo de Asia Times, donde David Goldman arguye que «el impacto acumulado de una serie de sanciones contra Rusia ha empujado a Rusia a una alianza estratégica con China, que incluye una estrecha cooperación con China en las telecomunicaciones 5G y la Investigación y Desarrollo (I&D) de semiconductores» cuando “la economía de Rusia podrá ser del tamaño de Italia, pero su cerebro (sic) es más grande que su cuerpo: donde se gradúan más ingenieros cada año que en EEUU, y están muy bien entrenados».

In a fast-changing technology-driven era, drafting an implementable strategic roadmap to achieve economic prosperity becomes a real challenge. Although the national and international strategic development plans may vary, they usually target the improvement of the quality of living standards through boosting the national GDP per capita and the creation of decent jobs. There is no doubt that human capacity building, through higher education, is vital to the availability of highly qualified workforce supporting the implementation of the aforementioned strategies. In other words, fulfillment of most strategic development plan goals becomes dependent on the drafting and implementation of successful higher education strategies. For MENA region countries, this is particularly crucial due to many specific challenges, some of which are different from those facing developed nations.

In economic literature, economic complexity is typically approximated on the basis of an economy’s gross export structure. However, in times of ever increasingly integrated global value chains, gross exports may convey an inaccurate image of a country’s economic performance since they also incorporate foreign value-added and double-counted exports. Thus, I introduce a new empirical approach approximating economic complexity based on a country’s value-added export structure. This approach leads to substantially different complexity rankings compared to the established metrics. Moreover, the explanatory power of GDP per capita growth rates for a sample of 40 lower-middle- to high-income countries is considerably higher, even if controlling for typical growth regression covariates.

El propósito que gobierna este escrito, de carácter reflexivo, se centra en ubicar la concepción moderna del concepto de desarrollo en un contexto de geopolítica y, a partir de allí, con la ciencia, la tecnología y la técnica, en una clara referencia conceptual en su carácter instrumental a herramienta geopolítica, referir la existencia de sociedades con instituciones políticas y mercados no inclusivos (o extractivos), que explican la formulación de categorías de países y la existencia de desigualdades.

La relación entre teoría y experimento ha estado siempre presente en la filosofía de la ciencia, especialmente en el debate entre tradiciones teóricas y experimentales. La cuestión está en el papel de la teoría y el experimento en la investigación científica y en el predominio de una tradición sobre otra. Históricamente, tanto para filósofos como historiadores de la ciencia ha predominado la idea de que la experimentación es subsidiaria de la teoría, pero hace ya unas décadas que esta concepción se ha puesto en cuestión. Por lo que respecta a las categorías de invención y de innovación históricamente se las ha asociado a la tecnología y a las ciencias aplicadas. Sin embargo, actualmente dichas categorías engloban la idea de cambio en cualquiera de los ámbitos, desde los científicos a los culturales y desde la tecnología a las formas de vida cotidiana, siendo también un referente para cambios metodológicos y epistemológicos.

Intuitionistic Propositional Logic is proved to be an infinitely many valued logic by Kurt Gödel (1932), and it is proved by Stanisław Jaśkowski (1936) to be a countably many valued logic. In this paper, we provide alternative proofs for these theorems by using models of Saul Kripke (1959). Gödel’s proof gave rise to an intermediate propositional logic (between intuitionistic and classical), that is known nowadays as Gödel or the Gödel-Dummet Logic, and is studied by fuzzy logicians as well. We also provide some results on the inter-definablility of propositional connectives in this logic.

The Copenhagen interpretation has been the subject of much criticism, notably by De Broglie and Einstein, because it contradicts the principles of causality and realism. The aim of this essay is to study the wave mechanics as an alternative to traditional quantum mechanics, in the continuity of the ideas of Louis de Broglie: the pilot wave theory of De Broglie (where each particle is associated with a wave which guides it), De Broglie-Bohm theory, stochastic electrodynamics (where the stochastic character of particles is caused by the energy field of the fluctuating vacuum), and the analogies between quantum mechanics and hydrodynamics.
