This paper discusses fundamental physical interactions starting from two preliminary assumptions.(a) Although mass of gravity and mass of inertia are equivalent quantities in their measured values, they are qualitatively not identical physical entities. We will take into consideration this difference in our equations. Then it extends this 'equivalence-is-not-identity' principle to sources of further fundamental interaction fields, other than gravity. (b) Physical interactions occur between these qualitatively different entities.First it interprets these assumptions. Then, it sketches a picture of fundamental physical fields influenced by the distinction between the two qualitative forms of the individual fieldcharges and interaction between them. It applies the results of a former publication (Darvas in Concepts Phys. VI(1):3-16, 2009), which mathematically proved the existence of an invariance between the two isotopic forms of field-charges. It introduces the notion of isotopic-field-charge-spin, proven as a conserved quantity. This conservation predicts the existence of a boson mediating between the two possible isotopic-field-charge-spin states. After these preliminary foundations, it formulates certain consequences in the author's view on the physical structure of matter. Finally the paper discusses how these issues can allow an alternative interpretation of physical experience.

This paper applies the isotopic field-charge spin theory (Darvas, IJTP 2011) to the electromagnetic interaction. First there is derived a modified Dirac equation in the presence of a velocity dependent gauge field and isotopic field charges (namely Coulomb and Lorentz type electric charges, as well as gravitational and inertial masses). This equation is compared with the classical Dirac equation. There is shown that, since the presence of isotopic fieldcharges would distort the Lorentz invariance of the equation, there is a transformation, which together with the Lorenz transformation restores the invariance of the equation, in accordance with the conservation of the isotopic field-charge spin (Darvas, 2009). The paper discusses the conclusions derived from the extensions of the Dirac equation. It is shown that in semiclassical approximation the model provides the original Dirac equation, and at significantly relativistic velocities it approaches to the Schrödinger equation. Among other conclusions, the clue gives physical meaning to the electric moment. The closing section summarises a few further conclusions and shows a few developments to be discussed in detail in a next paper (Darvas, 2013). A J J A J A what demonstrates an analogy with our formula derived in [22] based on the findings in this paper. Note also that the potential (Coulomb) charges behave like corpuscles, while the kinetic (Lorentz type) charges like waves [16]. This complementary double behaviour (formulated first by Bohr in 1927, then discussed in 1937 [5]) became subject of studies again (cf., [41]).

Ta más Farkas has developed a series of sets of graphic units that can be used to model the different properties of physical particles. One of the sets is demonstrated in this paper, which is the result of years of collaboration between a physicist and a graphic artist.The inner structure of atoms and the classification of quarks and their properties are not easy subjects to understand. This difficulty stems from the impossibility of real visualization of quarks, which closes the doors before the imagination. Physics education struggles with this problem of visualization, since all visualizations are schematic and are unable to show all sides and details of a physical model. Although physics education is attempting to resolve the problem, so too does Farkas's work.Below is the artist's statement on the significance of his work for both physicists and laypeople, followed by a physics-based discussion of the properties of quarks and how their properties can be seen as modeled in Farkas's work. TAMÁS F. FARKAS: INSIGHT INTO THE PROCESS OF VISUALIZATIONMy works have opened new insight into an impossible world and free vistas for artistic imagination [1], partly in higher dimensions and partly in geometric structures not realizable even in higher dimensions. Making visible spaces that are non-Euclidean, beyond traditional geometries, multidimensional and not realizable in the real world, these are also works that attract the interest of physicists studying the structure of matter. Application of colors and color-shades in the visualization may multiply the manifold of mutually perpendicular-or, through the use of straight lines, at least apparently perpendicular-(abstract) spatial dimensions.Moreover, these works make these conceptions visible and perceivable for those observers who are unfamiliar with abstract physical structures. Figures drawn by physicists are schematic, suitable only for illustrating dry physical facts. The world of sub-elementary particles is often too complex and difficult for non-physicist observers to grasp. Flavors, colors and other physical properties of the sub-elementary particles [2] can be interpreted only in multidimensional abstract fields (abstract even for physicists). These abstract fields themselves have complex, multidimensional structures. Therefore, physicists strive to represent the objects manifested in these fields with the simplest symbols possible (such as dots, arrows or wavy lines directed toward a given spatial axis).According to common belief, this world is too complicated to be represented simply, not even to attribute an internal structure to the represented objects. My pictorial world breaks this taboo. For three decades I have been investigating how to make visible the spatial world not perceivable by the everyday senses. The roots of my graphical world are partly in the arts and partly in the sciences (e.g. multidimensional geometry and the world of abstract symmetries). My graphical research into scientific profundities strives to create a harmony rooted in the...

This paper is a continuation of the article "The Isotopic Field-Charge Assumption Applied to the Electromagnetic Interaction". It continues the discussion and consequences of the extended Dirac equation in the presence of isotopic mass and electric charges, and a kinetic gauge field. In compliance with the author's previous papers (Darvas 2009, IJTP 2011, IJTP 2013), there appears a second conserved Noether current in the interaction between two electric charges in the presence of isotopic electric charges and a kinetic field.This second conserved current involves the conservation of the isotopic electric charge spin, and that predicts the existence of quanta of the kinetic field (dions associated with the photons). It is concluded that with the discussed conditions, the electromagnetic interaction should be mediated by photons and their dion partners together. The conclusions give physical meaning, among others, to the electric moment and to a virtual coupling spin.
