Depiction of Space-Time Ontological Geometry Based on Mulla Sadra and Einstein’s Epistemological Bases [PDF]
Journal of Philosophical InvestigationsThe purpose of this article is to explain the quality of creation and examine the essence of space-time based on Sadra'i philosophy and its comparison with physical propositions. The present descriptive-analytical article explores two issues. One is from

American Journal of Physics, 2005 At the 1927 Solvay conference, Albert Einstein presented a thought experiment intended to demonstrate the incompleteness of the quantum mechanical description of reality. In the following years, the experiment was modified by Einstein, de Broglie, and several other commentators into a simple scenario involving the splitting in half of the wave function

Einstein solvmanifolds and the pre-Einstein derivation [PDF]
Transactions of the American Mathematical Society, 2011 An Einstein nilradical is a nilpotent Lie algebra, which can be the nilradical of a metric Einstein solvable Lie algebra. The classification of Riemannian Einstein solvmanifolds (possibly, of all noncompact homogeneous Einstein spaces) can be reduced to determining, which nilpotent Lie algebras are Einstein nilradicals and to finding, for every ...

International Journal of Intelligent Systems, 2016 The objective of this article is to extend and present an idea related to weighted aggregated operators from fuzzy to Pythagorean fuzzy sets (PFSs). The main feature of the PFS is to relax the condition that the sum of the degree of membership functions ...

On homogeneous warped product Einstein metrics [PDF]
, 2014 In this article we study homogeneous warped product Einstein metrics and its connections with homogeneous Ricci solitons. We show that homogeneous $(\lambda,n+m)$-Einstein manifolds (which are the bases of homogeneous warped product Einstein metrics) are

The ultrafast Einstein–de Haas effect [PDF]
Nature, 2018 The Einstein-de Haas effect was originally observed in a landmark experiment1 demonstrating that the angular momentum associated with aligned electron spins in a ferromagnet can be converted to mechanical angular momentum by reversing the direction of ...

On the spherically symmetric Einstein-Yang-Mills-Higgs equations in Bondi coordinates
, 2012 We revisit and generalize, to the Einstein-Yang-Mills-Higgs system, previous results of D. Christodoulou and D. Chae concerning global solutions for the Einstein-scalar field and the Einstein-Maxwell-Higgs equations.

“El cántaro” o la creatividad de lo vacuo en la poesía de José Ángel Valente
Arbor: Ciencia, Pensamiento y Cultura, 2007 A través del comentario de “El cántaro”, uno de los poemas más importantes del Valente de Poemas a Lázaro (1960), se estudia la importancia de la androginia en la poesía y en la poética valentianas.
