In [16, Theorem 3.12, p. 397], Ungar answered a question of Burgess [2] by showing that every 2-homogeneous metric continuum is locally connected. A short, elementary and elegant proof of this result has been given by Whittington [17] who has omitted a powerful result of Effros (viz. Theorem 2.1 of [4, p. 39]) used by Ungar. It is observed in this note that Whittington's proof can be applied to...
This report extends the scope of computation with a non standard × to the more basic case of a non standard +, where standard means associative and commutative. Two physically meaningful examples of a nonstandard + are provided by the observation of motion in Special Relativity, from either outside (3D) or inside (2D or more), We revisit the “gyro”-theory of Ungar to present the polymorphic inf...
In general, D = E + 4πP and H = B − 4πM, where P and M are the densities of electric and magnetic polarization, respectively, while Abraham (and Minkowski) considered only linear media, where D = E and B = μH. All media except vacuum have both and μ different from unity. However, most media have μ , and most discussion [2] of the Abraham and Minkowski momenta assume that μ = 1. In this idealize...

BACKGROUND Calculating Abraham descriptors from solubility values requires that the solute have the same form when dissolved in all solvents. However, carboxylic acids can form dimers when dissolved in non-polar solvents. For such compounds Abraham descriptors can be calculated for both the monomeric and dimeric forms by treating the polar and non-polar systems separately. We illustrate the met...

The Abraham-Minkowski dilemma relates to the disputed value of the optical momentum within a dielectric medium and whether the free-space value should be divided (Abraham) or multiplied (Minkowski) by the refractive index. Although undoubtedly simplistic, these two approaches provide intuitive insight to many subtle problems in optical physics. This paper reviews a modified version of the Einst...
