Energy conditions in general relativity and quantum field theory [PDF]
This review summarizes the current status of the energy conditions in general relativity and quantum field theory. We provide a historical review and a summary of technical results and applications, complemented with a few new derivations and discussions.

Gödel; From Relativity to IdealismThe Consistency between Einstein’s Relativity Theory and Kant’s Philosophy of Time [PDF]
Einstein’s theory of relativity made many difficulties for Newtonian physics, so as it did not remain any way for keeping it but setting apart or reforming some of the most fundamental concepts such as space and time.

Oral surveillance and JAK inhibitor safety: the theory of relativity
The published results of the post-marketing ORAL Surveillance study, which compared the Janus kinase (JAK) inhibitor tofacitinib with anti-TNF therapy in older patients with rheumatoid arthritis who have cardiovascular risk factors, have led to changes ...

Relative elliptic Theory [PDF]
This paper is a review of relative elliptic theory (i.e., elliptic theory in the category of smooth embeddings) closely related to the Sobolev problem, first studied by Sternin in the 1960s. We consider both analytic aspects of the theory (the structure of the algebra of morphisms, ellipticity, Fredholm property) and topological aspects (index formulas

In this paper, it is shown that the super-potential defined by Einstein, Landau–Lifshitz, and Bergmann–Thompson in general relativity theory and in teleparallel gravity theory are equivalent for a general diagonal space–time metric. Therefore, the energy–

An alternative way to present a relativistic Lagrangian definition
As long we known, the non-relativistic Lagrangian definition, L = T − U with T and U as being, respectively, kinetic and potential energy, it is not valid at the relativistic level.

Virtual Reality Media: The Simulation of Relativity Theory on Smartphone
Learning physics science is ideally accomplished through the experiments, although the theory of special relativity is challenging to understand. It is difficult because this topic has not occurred in real experience, and no technology has launched at ...

Relative Quantum Field Theory [PDF]
We highlight the general notion of a relative quantum field theory, which occurs in several contexts. One is in gauge theory based on a compact Lie algebra, rather than a compact Lie group. This is relevant to the maximal superconformal theory in six dimensions.

Black Holes in an Effective Field Theory Extension of General Relativity. [PDF]
Effective field theory methods suggest that some rather general extensions of general relativity include, or are mimicked by, certain higher-order curvature corrections, with coupling constants expected to be small but otherwise arbitrary.

The Aesthetics of String Theory Design Structure as a Source for Innovating Creative Metal Pendants [PDF]
Nature, with its laws and systems latent within the smallest cells and particles of matter, is full of wonderful structural and aesthetic syntheses, which are utilized by the artist to build many linear, colorful or tactile rhythms.
