On the relativity of shapes
نویسنده
چکیده
As has been widely discussed [1], the presence of extra dimensions may provide a possible explanation not only for the hierarchy problem of the fundamental interactions, but also for the late time cosmic acceleration, with no need to invoke either a cosmological constant Λ or a quintessence field Φ. In this paper we use a model independent formulation of the so-called brane-world program [2, 3]. Although the extrinsic curvature must be taken into account are well known and have been studied at length in the lit-

Einstein structures on four-dimensional nutral Lie groups
When Einstein was thinking about the theory of general relativity based on the elimination of especial relativity constraints (especially the geometric relationship of space and time), he understood the first limitation of especial relativity is ignoring changes over time. Because in especial relativity, only the curvature of the space was considered. Therefore, tensor calculations should be to...
متن کاملThe Principle of Relativity: From Ungar’s Gyrolanguage for Physics to Weaving Computation in Mathematics
This paper extends the scope of algebraic computation based on a non standard $times$ to the more basic case of a non standard $+$, where standard means associative and commutative. Two physically meaningful examples of a non standard $+$ are provided by the observation of motion in Special Relativity, from either outside (3D) or inside (2D or more), We revisit the ``gyro''-theory ...
متن کاملBulk Viscous Bianchi Type VI0 Cosmological Model in the Self-creation Theory of Gravitation and in the General Theory of Relativity
In the second self-creation theory of gravitation and in the general theory of relativity, Bianchi type VI0 cosmological model in the presence of viscous fluid is studied. An exact solution of the field equations is given by considering the cosmological model yields a constant decelerations parameter q=constant and the coefficients of the metric are taken as A(t)=[c1t+c<su...
متن کاملCultural Relativity of Moral Precepts
The foundation of most intellectual discourse is Western-centric to the exclusion of other views. This includes ideal patterns of social interaction, preference for aesthetic, accepted norms and values, and the concepts of dignity, respectability, morality and ethics. Such a position is culturally myopic. Western cultural influence colors all of them including moral precepts. The assumption is ...
متن کاملLanguage Shapes Thought: Rethinking on Linguistic Relativity
We reviewed the researches on linguistic relativity in color, space and time domains, and rethink the relationship between language and perception to support the idea that language interact with other cognitive processes and shape the perception and thought of human. Language, perception and action are not separated systems, but are closely interconnected and highly interacted to some extent. A...
متن کاملEllipsoidal shapes in general relativity: general definitions and an application
A generalization of the notion of ellipsoids to curved Riemannian spaces is given and its possible use to describe the shapes of rotating bodies in general relativity is considered. As an illustrative example, stationary, axisymmetric perfect-fluid spacetimes with a so-called confocal inside ellipsoidal symmetry are investigated in detail under the assumption that the 4-velocity of the fluid is...
