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
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
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
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

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,

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]
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.
