Theory overview of Heavy Ion collisions
2016
This presentation discusses some recently active topics in the theoretical interpretation of high energy heavy ion collisions at the LHC and at RHIC. We argue that the standard paradigm for understanding the spacetime evolution of the bulk of the matter produced in the collision is provided by viscous relativistic hydrodynamics, which can be used to systematically extract properties of the QCD medium from experimental results. The initial conditions of this hydrodynamical evolution are increasingly well understood in terms of gluon saturation, and can be quantified using Classical Yang-Mills fields and QCD effective kinetic theory. Hard and electromagnetic probes of the plasma provide addit…
Conditions for statistical determination of the neutrino mass spectrum in radiative emission of neutrino pairs in atoms
2016
The photon spectrum in macrocoherent atomic de-excitation via radiative emission of neutrino pairs (RENP) has been proposed as a sensitive probe of the neutrino mass spectrum, capable of competing with conventional neutrino experiments. In this paper we revisit this intriguing technique in order to quantify the requirements for statistical determination of some of the properties of the neutrino spectrum, in particular the neutrino mass scale and the mass ordering. Our results are sobering. We find that, even under ideal conditions, the determination of neutrino parameters needs experimental live times of the order of days to years for several laser frequencies, assuming a target of volume o…
Argumentos retóricos sobre Interrupción Voluntaria del Embarazo en Colombia. Análisis jurisprudencial desde la teoría de la argumentación jurídica de…
2011
RESUMENEl presente trabajo aborda los conceptos planteados por Chaïm Perelman en su teoría de la argumentación, con el fin de lograr una comprensión del razonamiento en las decisiones judiciales tomadas por la Corte Constitucional de Colombia, en relación a tres casos sobre interrupción voluntaria del embarazo (IVE). En primer lugar, se aborda la teoría de la “Nueva Retórica” de Chaïm Perelman, y en especial su aplicación en el campo del Derecho. A continuación se hace un breve repaso de las premisas de la argumentación y las técnicas argumentativas manteniendo un enfoque de carácter jurídico. Para finalizar, se analiza la motivación de las sentencias de la Corte Constitucional colombiana …
Talking about something real: the concept of truth in multimodal non-fiction books for young people
2016
AbstractWithin social semiotics we discuss how different semiotic resources alone or in multimodal texts are used to communicate truth. This is one of the parts of the multimodal theory that are least developed and discussed. The discussion on truth within social semiotics is mainly focused on the relationship between a corresponding type of truth that is common in natural science and a more everyday perception of truth. This can give an incomplete and stereotypical image of how truth is portrayed. This essay attempts to nuance the picture by suggesting that our theoretical conceptions of how we portray truth visually can be nuanced and developed by combining the theory of multimodality wit…

This is my truth, tell me yours: some aspects of action research quality in the light of truth theories
2001
Abstract In this article the authors introduce some aspects of various truth theories in the context of action research. The traditional ways of determining quality are based on the correspondence theory of truth, which, in their view, conflicts with the basic assumptions of action research. The pragmatic theory of truth seems to be clearly represented in the world of action research. In their opinion, other theories of truth can be productively applied as well. In addition to the classical theories of truth – the correspondence theory, the coherence theory and the pragmatistic view on truth – they discuss the truth as ‘aletheia’ (a Heideggerian view on truth), as Habermasian consensus and …

Il fotografo bracconiere
2021
L’opera di Maurizio Galimberti ci ha abituato a vedere nella fotografia del Novecento, e anche in quella dei primi decenni del nuovo secolo, un repertorio inesauribile di mosse teoriche che egli – senza intellettualismi – ha saputo ripensare attraverso la sua peculiare prassi artistica. Maurizio Galimberti's work has accustomed us to seeing in the photography of the twentieth century, and also in that of the first decades of the new century, an inexhaustible repertoire of theoretical moves that he - without intellectualism - was able to rethink through his peculiar artistic practice.
Classical Field Theory of Gravitation
2012
The classical field theories developed in the preceding chapters all have in common that they are formulated on a flat spacetime, i.e. on a four-manifold which is a Euclidean space and which locally is decomposable into a direct product M 4 = ℝR3 ℝR of a physical space ℝR3 x of motions, and a time axis ℝRt. The first factor is the threedimensional space as it is perceived by an observer at rest while the time axis displays the (coordinate) time that he/she measures on his/her clocks. This spacetime is endowed with the Poincare group as the invariance group of physical laws and inherits the corresponding specific causality structure.
