A massless Weyl-invariant dynamics of a scalar, a Dirac spinor, and electromagnetic fields is formulated in a Weyl space, W4, allowing for conformal rescalings of the metric and of all fields with nontrivial Weyl weight together with the associated transformations of the Weyl vector fields κμ, representing the D(1) gauge fields, with D(1) denoting the dilatation group. To study the appearance of nonzero masses in the theory the Weyl symmetry is broken explicitly and the corresponding reduction of the Weyl space (...) W4 to a pseudo-Riemannian space V4 is investigated assuming the breaking to be determined by an expression involving the curvature scalar R of the W4 and the mass of the scalar, selfinteracting field. Thereby also the spinor field acquires a mass proportional to the modulus Φ of the scalar field in a Higgs-type mechanism formulated here in a Weyl-geometric setting with Φ providing a potential for the Weyl vector fields κμ. After the Weyl-symmetry breaking, one obtains generally covariant and U(1) gauge covariant field equations coupled to the metric of the underlying V4. This metric is determined by Einstein's equations, with a gravitational coupling constant depending on Φ, coupled to the energy momentum tensors of the now massive fields involved together with the (massless) radiation fields.

A new challenge for Bible translators A few decades ago the development of the dynamic-equivalent method of translation (which later became known as functional equivalence) broke radically away from the formal and traditional method of translation. Since then the functional-equivalent approach has undergone refinement, but the development can no longer be called revolutionary. However, research in the art of translation has now shifted from the method of translation to the format of the printed text (also called the paralinguistic features of (...) the text). In this article practical examples are given of how the employment of paralinguistic features can underscore the meaning of the text of the Bible, especially the Afrikaans Bible since it has become imperative to start working on a new translation.
