Using the mathematical aspects of Schwarzschild metric, we present different variables transformation which proves that central singularity hypothesis does not exist. The geometric interpretation black hole from metric is mathematically convincing. approaches taken by many authors were viewed, such as Painleve and its complex variant, to deduce a with throat sphere leads mirror space-time. Subs...
In these lectures I propose to push Einsteins principle of coordinate independence to the extreme in order to restrict the possible form of fundamental equations of motion in physics. I start from nearly tautological system theoretic axioms. They provide a minimal amount of a priori structure which is thought to be characteristic of human thinking in general. It is shown how formal discretizati...
Light-induced coleoptile stimulation and mesocotyl suppression in etiolated Avena sativa (cv. Lodi) has been quantitated. Etiolated seedlings showed the greatest response to light when they were illuminated 48 to 56 hours after imbibition. Two low-irradiance photoresponses for each tissue have been described. Red light was 10 times more effective than green and 1,000 times more effective than f...
The Plebanski–Demianski solution is a very general axially symmetric analytical solution of Einsteins field equations generalizing the Kerr solution. This solution depends on seven parameters, the mass, a rotation parameter, a cosmological constant, NUT parameter, electric and magnetic charges, and an acceleration. In this paper we present a general description of matter wave interferometry in ...
Scientific research is a systematic process aimed to build knowledge through a set of structured evaluations, thus generating the development of both the individual that performs research and the society in which it is developed. The objective of research is to produce knowledge, possibly applicable inside and outside researchersénvironments, and perhaps generate practical actions. Research met...
