Natural theology after Darwin

open access: yesHTS Teologiese Studies/Theological Studies, 2023
Has Darwinian science made natural theology obsolete, as many Christian scholars now believe? In this article, the author assumes that natural theology does not take place in a religious vacuum but instead borrows its sense of god from this or that ...

Einstein-Gauss-Bonnet Gravity in Four-Dimensional Spacetime. [PDF]

open access: yesPhysical Review Letters, 2019
In this Letter we present a general covariant modified theory of gravity in D=4 spacetime dimensions which propagates only the massless graviton and bypasses Lovelock's theorem.

Remarks on the Theory of Relativity (1922)

open access: yesJournal of French and Francophone Philosophy, 2020
On April 22, 1922, the Societé française de Philosophie hosted Albert Einstein for a discussion of the theory of relativity.  In the course of this discussion, Henri Bergson, who was at that time writing Duration and Simultaneity, which explored some of ...

L’Académie face au seuils critiques (Montaigne, Descartes et Einstein comme références) [PDF]

open access: yesMemoirs of the Scientific Sections of the Romanian Academy, 2023
The study approaches the general crisis, manifested nowadays almost all around the world, related to the loss of confidence in the academic models and academic, once so cherished, values.

On generalized G-recurrent manifolds [PDF]

open access: yesSurveys in Mathematics and its Applications, 2021
In this paper, we define a type of Riemannian manifold called generalized G-recurrent manifold, and study the various properties of such a manifold. Among others, it is shown that if a generalized G-recurrent manifold is Einstein, then its associated 1 ...

Exact Solutions of Einstein's Field Equations [PDF]

open access: yes, 2004
We examine various well known exact solutions available in the literature to investigate the recent criterion obtained in Negi and Durgapal [Gravitation and Cosmology7, 37 (2001)] which should be fulfilled by any static and spherically symmetric solution

Quantum liquid droplets in a mixture of Bose-Einstein condensates [PDF]

open access: yesScience, 2017
Making dilute quantum droplets In recent years, quantum fluids have been studied largely in gaseous form, such as the Bose-Einstein condensates (BECs) of alkali atoms and related species. Quantum liquids, other than liquid helium, have been comparatively

La Física al encuentro de la complejidad

open access: yesArbor: Ciencia, Pensamiento y Cultura, 2007
A propósito de la conmemoración del Año Mundial de la Física 2005 se presenta una visión panorámica de la física de los sistemas complejos, que constituye una nueva frontera de la Física cuyos orígenes se remontan a comienzos del siglo XX, pero cuyo ...

Rigidity results for closed vacuum static spaces

open access: yesAIMS Mathematics, 2023
In this paper we studied rigidity results for closed vacuum static spaces. By using the maximum principle, we achieved rigidity theorems under some pointwise inequalities and showed that the squared norm of the Ricci curvature tensor was discrete.
