We know to some extent about the relationship between Galilean relativity and the Doppler Effect. In this paper, we will show the natural close relationship between these “two phenomena” in physics, from which we conclude that there are not two, but only one phenomenon—the relative motion expressed by different quantities.

The object of this article is to present a new theory based on the introduction of a non-material medium which makes it possible to obtain a Preferred Frame of Reference (in the context of special relativity) or a Reference (in the context of general relativity), that is to say a dynamic medium of reference. The theory of the dynamic medium of reference is an extension of Lorentz‐Poincaré’s theory in the domain of gravitation in which instruments (clocks, rulers) are perturbed by gravitation and where only the measure of the speed of light always gives the same result. The presence of a massive body creates a centripetal flux of the medium, which has three fundamental effects: the dilatation of the period of material clocks, the contraction of the length of material rulers, and the slowdown of light. Thanks to the centripetal flux of the medium and these three effects, it is possible to find the correct expression of the deflection of a ray of light and the Shapiro delay. The dynamic medium of reference allows to establish a gravitational transformation and to find the fundamental equations of movement for light and matter. Hence, the theory of the dynamic medium of reference allows to find the main results of general relativity, but with important differences: The simultaneity is absolute, existence of the Preferred Frame of Reference, the physical reality is the universal present moment and not a global space-time (block-universe), light is slowed down by a gravitational field.

Xenon plus a molecular solid solute that yields a positive excess enthalpy of solution reaction form the working fluid for a transcritical power cycle. Xenon exhibits large changes in induced polarities with the change in density in the temperature and pressure range of the cycle described. A difference in excess enthalpy of solution between the reaction in xenon’s dense liquid state and expanded supercritical fluid state affects the cycle’s efficiency by internally elevating the temperature of heat input from near the cycle’s T2 to near its T1 before that energy affects gas expansion. This positive excess enthalpy differential establishes conditions in the cycle that allows for complete exhaust heat regeneration. The energy transfer invalidates Carnot’s and Clausius’s original assumption that the rate an ideal gas can convert heat energy to work by its expansion and contraction establishes heat as the lowest form of energy to which all other forms degrade.

We explore computational geometry, particularly the three-dimensional (3D) contours of the electrostatic potential due to electrical charges with similar and also opposite polarity. We also explore the 3D contours of the gravitational potential by computational geometry. The noticeable outcome of these exercises is that electrostatic interaction affects the geometry of the space as does the gravitational interaction but with the difference that electrostatic interaction affects the geometry of the space differently for charges with different polarity and at different distance scales.
