Bold Visions in Educational Researchbig bang implies a breakdown of the concept of spacetime geometry, and they have come to recognize it as an inevitable feature of Einstein’s general relativity. It is a feature that prevents the physicist from investigating what happened at . = 0 or prior to it. To some physicists, this abrupt termi

The Production of Male Motheringportance in the analysis of problems in gravitation physics. Most of the theories of gravitation today model the spacetime as a four-dimensional differentiable manifold on which a Lorentzian metric tensor is globally defined. After setting up this basic framework in Section 2, we discuss spacetime d

Photobioreactor-Based Energy Sources,rious branches of abstract mathematics can be classified by means of the groups of transformations which preserve the properties of objects studied in that branch. For example, Euclidean geometry can be considered to be the study of the properties of objects which are left invariant under the Euclid

The mess is usually absorbed into the theory by a suitable renormalization of the coupling constants. Over the years, a number of elaborate methods have been developed to carry out this procedure. Simple normal ordering which removes

,The Quest for a Name in “Frost”, following discussion, we shall consider the basic, elementary structural aspects of static and rotating black holes — pointing out the inherent differences between them — and the corresponding physical phenomena. At the end, we shall touch upon a few other features of black holes that would be of r

C. P. Wong,Kyoung-sik (Jack) Moonexpressions, I personally am very biased and committed to the use of the zeta function regularization scheme. This bias is perhaps due to my own subjective notion of elegance and compactness that this scheme offers.
