Equivalence-principle Analog of the Gravitational Redshift

What happens when two synchronized clocks on a rigid beam are both given the exact same acceleration profile? Will they remain synchronized? What if we use a rigid-rod Rindler acceleration profile? The special relativity prediction surprises many people. This experimental setup is the special-relativity analog of the gravitational redshift. Just like two clocks higher and lower in a gravitational field lose synchronization, one sees a loss of synchronization in these clocks with `identical’ acceleration profiles. To the best of our knowledge this equivalence principle analog has never been directly measured, and current experimental techniques are sensitive enough to measure it. We discuss the origin of the essential physics behind this synchronization loss, and some special conditions which simplify its experimental observation.

Nos volvieron a derrotar y por la misma causa

Hoy toda la política del circo socialdemócrata gira alrededor de la constituyente y el 350. De esta manera, la situación es muy halagadora para el capitalismo: pase lo que pase la opción revolucionaria no cuenta, no participa de la disputa, estamos ante un triunfo incuestionable del capitalismo y una derrota para el Socialismo. El prestigio de la ignorancia y la satanización del estudio, repetir la conducta adeca del Juan Bimba, obstaculizó una organización para los desposeídos y una teoría soporte para la revolución. No pudieron reconocerse y construirse como fuerza revolucionaria. Los llamados a ser su vanguardia se dejaron atrapar en la idea difusa de “pueblo sabio”, y de esta manera la vanguardia se pasmó, fue delito.

La medición y el estructuralismo científico

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.

Superposition principle and Kirchhoff’s integral theorem

The need for modification of the Huygens-Fresnel superposition principle arises even in the description of the free fields of massive particles and, more extensively, in nonlinear field theories. A wide range of formulations and superposition schemes for secondary waves are captured by Kirchhoff’s integral theorem. We discuss various versions of this theorem as well as its connection with the superposition principle and the method of Green’s functions. A superposition scheme inherent in linear field theories, which is not based on Kirchhoff’s integral theorem but instead relies on the completeness condition, is also discussed.

On the arithmetic of graphs

The Zykov ring of signed finite simple graphs with topological join as addition and compatible multiplication is an integral domain but not a unique factorization domain. We know that because by taking graph complements, it becomes isomorphic to the strong Sabidussi ring with disjoint union as addition. We prove that the Euler characteristic is a ring homomorphism from the strong ring to the integers by demonstrating that the strong ring is homotopic to a Stanley-Reisner Cartesian ring. More generally, the Kuenneth formula holds on the strong ring so that the Poincare polynomial is compatible with the ring structure. The Zykov ring has the clique number as a ring homomorphism. Furthermore, the Cartesian ring has the property that the functor which attaches to a graph the spectrum of its connection Laplacian is multiplicative. The reason is that the connection Laplacians do tensor under multiplication, similarly to what the adjacency matrix does for the weak ring. The strong ring product of two graphs contains both the weak and direct product graphs as subgraphs.

US Demands “Much Greater” Chinese Pressure on North Korea, or Else

In what amounted to a barely disguised threat, US Secretary of State Rex Tillerson yesterday declared that China had to “exert much greater economic and diplomatic pressure” on North Korea to abandon its nuclear and missile programs, if it “wants to prevent a further escalation in the region.” In other words, if Beijing fails to rein in the Pyongyang regime, the US could resort to military measures. Tillerson’s remarks followed a top-level meeting in Washington between him and US Defence Secretary James Mattis and their Chinese counterparts—China’s foreign policy chief Yang Jiechi and General Fang Fenghui, chief of the People’s Liberation Army’s joint staff department.

Lecciones del rentismo: lo que Venezuela no debe olvidar

En la IV República un alto porcentaje del ingreso petrolero se destinó a financiar el capitalismo rentístico con préstamos a bajas tasas de interés y largos plazos; la asignación de petrodólares baratos para importar maquinarías, insumos y tecnología; así como compras gubernamentales en condiciones muy favorables para la producción nacional. En la V República el mayor porcentaje de los ingresos petroleros se utilizó para financiar el neo-rentismo socialista como un modelo de dominación sustentado en el uso del ingreso petrolero para financiar la inversión social y crear una red clientelar que le sirve de apoyo político. El capitalismo rentístico y el neo-rentismo socialista son expresiones distintas del mismo modelo de acumulación extractivista. Los actores económicos, políticos y sociales se acostumbran a obtener ganancias e ingresos que no son fruto de su propia inversión ni de su trabajo productivo.

Deep Learning in (and of) Agent-Based Models: A Prospectus

A very timely issue for economic agent-based models (ABMs) is their empirical estimation. This paper describes a line of research that could resolve the issue by using machine learning techniques, using multi-layer artificial neural networks (ANNs), or so called Deep Nets. The seminal contribution by Hinton et al. (2006) introduced a fast and efficient training algorithm called Deep Learning, and there have been major breakthroughs in machine learning ever since. Economics has not yet benefited from these developments, and therefore we believe that now is the right time to apply Deep Learning and multi-layered neural networks to agent-based models in economics.

The destinal question of language

How can we think the destinal place of language in the essentially historical condition of our existence if such historicity cannot be understood on the basis of the labor of negativity alone? The attempt is made here to think language in a more originary manner, as non-negative finitude, that affirms what is outside dialectical-speculative closure, what is to come. The notion of ‘destinal’ itself is thus transformed. No longer being merely a categorical grasp of “entities presently given”, language is an originary exposure to the event of arrival in its lightning flash. Destiny appears as that of the messianic arrival of the ‘not yet’ which is not a telos that the immanent movement of historical reason reaches by an irresistible force of the negative. This essay reads Schelling, Heidegger and Kierkegaard to think language as a “place” of exposure to the non-teleological destiny that may erupt even today, here and now, without any given conditionality.

A more loyal PLA rebuffs the heresy of separating the Party and military

The PLA’s flagship newspaper, the PLA Daily, has published several articles in the past few months reaffirming the military’s strong will to follow the core of the Party’s central committee. Xi Jinping, General Secretary of the CPC Central Committee, Chinese President and Chairman of the Central Military Commission, the country’s top military authority, was endorsed as the “core” of the CPC central committee in October last year. Calls for the “nationalization of the army,” which mostly came from those who wish to see fundamental changes in China’s political system, have tapered off recently. Many high-ranking military officials and PLA publications have openly refuted those voices, saying their proposition is simply an attempt to create distance between the military and the Party. Peng Guangqian, a major general and a strategist at the Academy of Military Sciences, agreed. He said that “Some individual servicemen might attempt to command the Party and push the Party out to make way for themselves, which is absolutely not allowed and they must be eliminated from the army.” “These people actually want to seize the control of ‘the knife’ from the Party and undermine its leadership,” Peng argued. “We should learn the lessons from the collapse of the Soviet Union, in which the Communist Party gave up its leadership over the army.”
