Why the Bradley aberration cannot be used to measure absolute speeds. A comment

In a recent article in this journal [G. Sardin, Measure of the absolute speed through the Bradley aberration of light beams on a three-axis frame, Europhys. Lett. 53 (2001) 310], Sardin proposed to use the Bradley aberration of light for the construction of a speedometer capable of measuring absolute speeds. The purpose of this comment is to show that the device would not work.Comment: 2 pages, LaTeX, accepted for Europhysics Letter

Fundamentals of the Orbital Conception of Elementary Particles and of their Application to the Neutron and Nuclear Structure

An alternative approach to the Standard Model is outlined, being motivated by the increasing theoretical and experimental difficulties encountered by this model, which furthermore fails to be unitary. In particular, the conceptual uneasiness generated by the excessive multiplicity of fundamental elements of the Quark Model, 36 different quarks whose cohesion needs 8 different types of gluons, has logically led some physicists to propose a variety of quark substructures in an effort to reach unity. In order to avoid the forward escape corresponding to the attribution of a substructure to quarks and to stand away from the conceptual strangling to which the Standard model has led, we have instead opted for different fundamentals. These, in contrast to those of the Standard Model, are extremely simple and based on the assumption of a single fundamental corpuscle, of dual manifestation as corpuscle and anticorpuscle, to which is always associated an orbital that determines the structure of particles. In such a frame particles differentiate through the diversity of quantum states of their structuring orbital, in contrast to the strategy used by the Standard Model based instead on the particle's multiplicity of composition through the variety of the quark's content, furthermore limited to hadrons. Instead the orbital conception of particles is unitary, unifying all of them as well as their interactions. As an outstanding feature, nuclear forces derive from the neutron orbital structure, based on a proton core and a shell. This shell constitutes the cohesive element of nuclear structure.Comment: PDF 194 KB. You may get more information at http://www.sardin.co
