El Método de Descartes

open access: yesPraxis Filosófica, 2001
La revolución filosófica del siglo XVII es indisociable de la nueva ciencia y de la nueva forma de ver las cosas. Así, cuando Galileo ve caer un cuerpo, ya no se pregunta «¿por qué (dióti)?», sino «¿cómo?» cae ese cuerpo.

El análisis de la ciencia por medio de la literatura: Newton interpretado por Voltaire

open access: yesEstudios Franco-Alemanes. Revista internacional de Traducción y Filología, 2023
La figura de Isaac Newton fue fundamental para la evolución de la ciencia en Europa y en el mundo. Completando la tarea de Galileo y Kepler en el siglo XVII, Newton contribuyó con importantes aportaciones en el campo de las matemáticas, la astronomía, la

Pointed Hopf algebras over nonabelian groups with nonsimple standard braidings

open access: yesProceedings of the London Mathematical Society, Volume 127, Issue 4, Page 1185-1245, October 2023., 2023
Abstract We construct finite‐dimensional Hopf algebras whose coradical is the group algebra of a central extension of an abelian group. They fall into families associated to a semisimple Lie algebra together with a Dynkin diagram automorphism. We show conversely that every finite‐dimensional pointed Hopf algebra over a nonabelian group with nonsimple ...

A tool to understand emission mechanisms of blazars through their high‐energy gamma‐ray emission

open access: yesAstronomische Nachrichten, Volume 344, Issue 6, August 2023., 2023
The blazar SED is characterized by two energy components. Evidence suggests that the low‐energy component is generated by the synchrotron mechanism, but for the high‐energy component, the mechanism is still uncertain. Two main models have been proposed to explain this emission. According to the leptonic model, a correlation between the emission of both

Measurements of Size and Electrical Charges Carried by Precipitation Particles During RELAMPAGO Field Campaign

open access: yesEarth and Space Science, Volume 9, Issue 9, September 2022., 2022
Abstract The electrical charge carried by raindrops provides significant information about thunderstorm electrification mechanisms, since the charge acquired by hydrometeors is closely related to the microphysical processes that they undergo within clouds. Investigation of charges on raindrops was conducted during the Remote sensing of Electrification,

Extending the Conversion Rate of Sulfur Infiltrated into Microporous Carbon in Carbonate Electrolytes

open access: yesBatteries &Supercaps, Volume 5, Issue 5, May 2022., 2022
Li‐S cell design: Extending the discharge to 0.5 V in the formation cycles results in cracks formation and enables higher energy density. Abstract Infiltration of sulfur into microporous carbon enables the use of carbonate‐based electrolytes due to the formation of a compact cathode electrolyte interface.

Some considerations about the relationship between science and philosophy in ptolemaic writings: an analysis from its teleological model of explanation [PDF]

open access: yes, 2018
Existe en nuestros días abundante bibliografía que se ha ocupado de presentar al astrónomo alejandrino como un científico empirista abocado a la tarea de salvar las apariencias y desvinculado de todo tipo de reflexión filosófica.
