Contra $beta^{*}$-continuous and almost contra $beta^{*}$-continuous functions

The notion of contra continuous functions was introduced and investigated by Dontchev. In this paper, we apply the notion of $beta^{*}$-closed sets in topological space to present and study a new class of functions called contra $beta^{*}$-continuous and almost contra $beta^{*}$-continuous functions as a new generalization of contra continuity.

Complexity: Order contra Chaos

A concise commentary on observing and modeling complexity within the framework of dynamical systems, information, and computation theories. Deterministic chaos, randomness, order, predictability, uncertainty, and complexity are contrasted. The descriptive abstraction of state is seen to be a natural extension of the symbolization necessary for language and of the number concept. Philosophical c...

The Wilson-Wilson Experiment

An example of unipolar induction is a slab of material with (relative) permittivity and (relative) permeability μ that is immersed in a uniform external magnetic field H0 parallel to the plane of the slab, such that if the slab has velocity v perpendicular to H0 but also in the plane of the slab, a nonzero voltage difference V is detected between sliding contacts (fixed in the laboratory) on op...
