Nonlinear Theory of Elementary Particles Part X: The Theory of Massive Neutrino (by Alexander G. Kyriakos): Abstract: In this article the theory of massive neutrino is presented. This theory does not contradict with the last data of neutrino experiments, as the Standard Model theory. The neutrino of this theory is a massive neutral particle with half spin; all neutrinos are left-handed only and all antineutrinos are right-handed only. In the theory it is shown that neutrino is not the Majorano particle, but the Dirac particle. The total lepton number is strictly conserved. The total lepton flavour numbers can not be conserved. http://prespacetime.com/index.php/pst/article/view/189

Bianchi Type III Magnetized Anisotropic Dark Energy Models with Constant Deceleration Parameter (by S. D. Tade, Manish M. Sambhe): Abstract: The Bianchi type III magnetized dark energy model with constant deceleration parameter is investigated. The energy-momentum tensor consists of anisotropic fluid with anisotropic EoS p = ωρ and a uniform magnetic field of energy density ρB.We obtain exact solutions to the field equations using the condition that expansion is proportional to the shear scalar . The physical behavior of the model is discussed with and without magnetic field. We conclude that universe model as well as anisotropic fluid does not approach isotropy through the evolution of the universe. The physical aspects of the dark energy models are discussed. http://prespacetime.com/index.php/pst/article/view/187

Some Comments inspired by Dainis Zeps' Quanta Mathematica Instrumentalis (by Matti Pitkänen): Abstract: The ideas introduced by Dainis Zeps in the article Quanta Mathematica Instrumentalis and related articles are discussed in the conceptual framework of Topological Geometrodynamics. The concrete realization for the vision about physics as mathematics is discussed in TGD context and the idea about instrumentalism as key element of mathematics and science is analyzed and criticized. Also the notions of theorem and quantum windows, higher observer, and information field are discussed. http://prespacetime.com/index.php/pst/article/view/183

Nonlinear Theory of Elementary Particles Part IX: Physical Vacuum and Its Effect on Elementary Particles (by Alexander G. Kyriakos): Abstract: The first purpose of this article is to describe the influence of physical vacuum (PV) on the characteristics of particles (e.g. electron) and their interactions. Our second purpose is to show that all methods of calculation of this influence, which are used in quantum field theory (QFT), can be represented in electromagnetic (EM) form within the framework of nonlinear theory of elementary particles (NTEP). http://prespacetime.com/index.php/pst/article/view/180

Microscopes and Telescopes for Theoretical Physics: How Rich Locally and Large Globally is the Geometric Straight Line? (by Elemer E. Rosinger): Abstract: One is reminded in this paper of the often overlooked fact that the geometric straight line, or GSL, of Euclidean geometry is not necessarily identical with its usual Cartesian coordinatisation given by the real numbers in R. Indeed, the GSL is an abstract idea, while the Cartesian, or for that matter, any other specific coordinatisation of it is but one of the possible mathematical models chosen upon certain reasons. And as is known, there are a variety of mathematical models of GSL, among them given by nonstandard analysis, reduced power algebras, the topological long line, or the surreal numbers, among others. As shown in this paper, the GSL can allow coordinatisations which are arbitrarily more rich locally and also more large globally, being given by corresponding linearly ordered sets of no matter how large cardinal. Thus one can obtain in relatively simple ways structures which are richer locally and large globally than in nonstandard analysis, or in various reduced power algebras. Furthermore, vector space structures can be defined in such coordinatisations. Consequently, one can define an extension of the usual Differential Calculus.

This fact can have a major importance in physics, since such locally richer and globally larger coordinatisations of the GSL do allow new physical insights, just as the introduction of various microscopes and telescopes have done. Among others, it and general can reassess special relativity with respect to its independence of the mathematical models used for the GSL. Also, it can allow the more appropriate modeling of certain physical phenomena. One of the long vexing issue of so called “infinities in physics" can obtain a clarifying reconsideration. It indeed all comes down to looking at the GSL with suitably constructed microscopes and telescopes, and apply the resulted new modeling possibilities in theoretical physics. One may as well consider that in string theory, for instance, where several dimensions are supposed to be compact to the extent of not being observable on classical scales, their mathematical modeling may benefit from the presence of infinitesimals in the mathematical models of the GSL presented here. However, beyond all such particular considerations, and not unlikely also above them, is the following one: theories of physics should be not only background independent, but quite likely, should also be independent of the specific mathematical models used when representing geometry, numbers, and in particular, the GSL. One of the consequences of considering the essential difference between the GSL and its various mathematical models is that what appears to be the definitive answer is given to the intriguing question raised by Penrose : “Why is it that physics never uses spaces with a cardinal larger than that of the continuum?"

However, while we cannot ever pin down any specific physical reality for the reasons mentioned above, we can pin down the nature of physical reality as a whole. We cannot get to the end of a rainbow, because rainbows only appear to have an end. However, we can understand the true nature of the rainbow and understand how it is created and why it appears as it does. In the same way, although we cannot pin down any specific physical reality, we can understand the nature of physical reality as a whole, how physical reality is created and why physical reality appears as it does, if we are able to understand what it is that the phenomena of wave-particle duality and uncertainty are actually telling us about the nature of physical reality. http://prespacetime.com/index.php/pst/article/view/179

Higgs-Free Symmetry Breaking from Critical Behavior near Dimension Four (by Ervin Goldfain): Abstract: Starting from the infrared limit of Yang-Mills theory, we introduce here a Higgs-free model in which symmetry breaking arises from critical behavior near dimension four. Electroweak bosons develop mass near the Wilson-Fisher point of Renormalization Group flow. The family structure of Standard Model is recovered using the technique of “epsilon expansion”. We also find that dimensional regularization offers a straightforward solution to the cosmological constant problem. http://prespacetime.com/index.php/pst/article/view/175

Physical Foundation of the Theory of Fields: The Theory of Informatons (by Antoine Acke): Abstract: In the classical theory of fields the gravitational and the electromagnetic interactions are understood as the effects of “fields” on matter. Although those fields are considered to belong to the physical world, the theory remains vague about their nature: they are threatened as purely mathematical structures. In this article we propose a theory that introduces “information” as the substance of both gravitational and electromagnetic fields. The phenomena and the laws of gravito-electromagnetism and of electromagnetism can perfectly be deduced from the dynamics of the elementary entities that constitute that substance. We call these entities “informatons” and it is been shown that photons and gravitons can be identified as informatons transporting an energy quantum. The theory of informatons suggests a perfect isomorphism between G.E.M. and E.M. We will show that this - also with regard to the force laws - is compatible with special relativity.

FRW Cosmological Models in a Saez-Ballester's Scalar-tensor Theory of Gravitation (by Shivdas D Katore): Abstract: Explicit field equations of a scalar tensor theory of gravitation proposed by Saez and Ballester are obtained with an aid of a five dimensional FRW metric in the presence of perfect fluid source. Exact solutions of the field equations are derived when the metric potentials are functions of cosmic time only. The model reduces to curvature free (k=0) expanding stiff fluid cosmological model. Some physical and geometric properties of the solutions are also discussed. http://prespacetime.com/index.php/pst/article/view/178
