Edgardo Lander: “En Venezuela, sencillamente, la gente está harta”

Por • 20 sep, 2016 • Category: Nacionales

Prodavinci Septiembre 20 de 2016.- En la casa de Edgardo Lander hay trazos de su estadía en México y varios países de África. Su cara es conocida en los movimientos sociales de América Latina y otros continentes. Su pensamiento es de izquierda, acendrado en la academia y en un estudio continuo. Recientemente, escribió un «paper» […]

Urban Energy Flux: Human Mobility as a Predictor for Spatial Changes

Por • 18 sep, 2016 • Category: Crítica

As a key energy challenge, we urgently require a better understanding of how growing urban populations interact with municipal energy systems and the resulting impact on energy demand across city neighborhoods, which are dense hubs of both consumer population and CO2 emissions. Currently, the physical characteristics of urban infrastructure are the main determinants in predictive modeling of the demand side of energy in our rapidly growing urban areas; overlooking influence related to fluctuating human activities. Here, we show how applying intra-urban human mobility as an indicator for interactions of the population with local energy systems can be translated into spatial imprints to predict the spatial distribution of energy use in urban settings.

Eleazar Díaz Rangel 18/09/2016. Hoy culmina la XVII Cumbre del Movimiento de Países No Alineados. Como se ha recordado en estos días, fue fundado por Nehru, Nasser, Sukarno, Tito, jefes de Estado independientes, cuando la política mundial la dominaban las tensiones, o excepcionales acuerdos entre los dos grandes bloques encabezados por Estados Unidos y la […]

Chance in the Everett interpretation

Por • 18 sep, 2016 • Category: Filosofía

The notion of objective probability or chance, as a physical trait of the world, has proved elusive; the identification of chances with actual frequencies does not succeed. An adequate theory of chance should explain not only the connection of chance with statistics, but with degrees of belief, and more broadly the entire phenomenology of (seemingly) chance events and their measurement. Branching structure in the decoherence-based many worlds theory provides an account of what chance is that satisfies all these desiderata, including the requirement that chance involves uncertainty.

Toward a history of mathematics focused on procedures

Por • 18 sep, 2016 • Category: Ambiente

Abraham Robinson’s framework for modern infinitesimals was developed half a century ago. It enables a re-evaluation of the procedures of the pioneers of mathematical analysis. Their procedures have been often viewed through the lens of the success of the Weierstrassian foundations. We propose a view without passing through the lens, by means of proxies for such procedures in the modern theory of infinitesimals. The real accomplishments of calculus and analysis had been based primarily on the elaboration of novel techniques for solving problems rather than a quest for ultimate foundations. It may be hopeless to interpret historical foundations in terms of a punctiform continuum, but arguably it is possible to interpret historical techniques and procedures in terms of modern ones.

The theoretical physics ecosystem behind the discovery of the Higgs boson

Por • 18 sep, 2016 • Category: Ciencia y tecnología

The discovery of the Higgs boson in 2012 was one of the most significant developments of science in the last half century. A simplified history has Peter Higgs positing it in the mid-1960s followed by a long wait while experimentalists progressively turned up collider energies until it appeared several decades later. However, in order for both the hypothesis and the experimental discovery to occur, a vast and complex theory ecosystem had to thrive in the years before Higgs’s hypothesis and in the years that followed, building up to its discovery. It is further claimed that the Higgs boson hypothesis was an immoderate speculation, and therefore faith in theory argumentation and speculation was mandatory for the discovery program to proceed and reach its fulfillment. The Higgs boson could not have been discovered experimentally by accident.

The G20 and China’s Grand Vision for Righting the Global Economy

Por • 18 sep, 2016 • Category: Opinion

The G20 suffers from a number of imbalances at present. The first one is the imbalance of investment in finance versus the “real” economy which is getting worse after the 2008 crisis. Investment in the financial sector is usually overflowing, but in real-world sectors like industrialization and infrastructure building, current investment is nowhere near enough There is an urgent need to guide investment from the pure financial sectors to the real ones. After all, the real economy is the ultimate driving force of economic growth.

Marx sin reservas. Seis tesis para interpretar El capital a partir de la Lógica de Hegel

Por • 14 sep, 2016 • Category: Economía

Si no es posible comprender el desarrollo de El Capital sin conocer la Ciencia de la lógica, se busca trazar los lineamientos generales para alcanzar dicha comprensión. En seis tesis se ponen de relieve algunos aspectos importantes del pensamiento de Marx que han sido poco tratados, y se dialoga con la tradición marxista para señalar ciertos equívocos y resaltar algunas interpretaciones. Esto permite ofrecer un nuevo cuadro para entender la actitud crítica que adopta el “último” Marx frente a la dialéctica de su maestro.
